Technical Field

The present disclosure relates to a display apparatus forming a wall-mounted display and a control method thereof, and more particularly, to a display apparatus connected to at least one display apparatus for forming a wall-mounted display and a control method thereof.

Background

A wall-mounted display is a display in which a plurality of display devices for outputting images are arranged in a plane and each of the arranged plurality of display devices outputs a part of one image, so that the plurality of display devices operate like one display device having a large screen.

Such a wall-mounted screen displays a high-resolution image on a large screen, thereby providing visual satisfaction to a user.

Recently, wall-mounted displays are installed in various places such as malls, show halls, exhibition halls, trade fairs, and the like, and thus technologies related to the wall-mounted displays are also increasing.

In particular, one image is displayed on a plurality of display devices included in a wall-mounted display, and thus, a technology related to a method of transmitting an image to a plurality of display devices is required.

In this regard, recently, in order to transmit images to a plurality of display devices in a wall-mounted display in a stable manner, a redundancy technique is used, in which the same image is transmitted in a direction opposite to a direction in which the image is transmitted in the wall-mounted display.

Specifically, if a display device in a wall-mounted display does not receive an image or there is an error in the received image, the display device may display the image using a redundant image.

The above information is presented merely as background information to aid in understanding the present disclosure. As to whether any of the above information is applicable as prior art for the present disclosure, no determination has been made and no statement has been made.

Fig. 1A to 1C are diagrams provided to explain a display device according to an embodiment.

The display apparatus 100 according to the embodiment is a modular display forming a wall-mounted display, and may be a cabinet. The display apparatus 100 according to the embodiment may include at least one display module.

For example, referring to fig. 1A, a display apparatus 100 according to an embodiment may include six display modules 101, 102, 103, 104, 105, and 106. Here, each of the display modules 101, 102, 103, 104, 105, and 106 may be physically connected.

For example, as shown in fig. 1A, the display apparatus 100 may be configured such that a plurality of display modules 101, 102, 103, 104, 105, and 106 are connected in a 2 × 3 arrangement.

Here, the Light Emitting Diode (LED) display modules in the 2 × 3 arrangement are merely examples, and the arrangement pattern and the number of the LED display modules may be changed in various ways.

The display apparatus 100 may include a substrate (not shown), wherein each of the display modules 101, 102, 103, 104, 105, and 106 may be mounted on the substrate (not shown). Here, the substrate (not shown) may be implemented in a form in which each display module is mounted on the front surface of the substrate.

Further, the display apparatus 100 according to the embodiment may include a plurality of connection parts 11-1, 11-2, and 11-3 that may be combined with other display apparatuses (not shown). Further, the positions and the number of the connection portions in fig. 1A are merely examples, and the positions and the number of the connection portions may be changed in various ways.

Accordingly, the display apparatus 100 according to the embodiment may be implemented as a modular display apparatus, such as a wall-mounted display, by being combined with other display apparatuses.

Referring to fig. 1B, a plurality of display devices 100-1 to 100-16 may be combined in a 4 × 4 form to implement a wall-mounted display 1000. Here, the wall-mounted display of the 4 × 4 arrangement is merely an example, and the arrangement pattern and the number of display devices may be changed in various ways.

The wall-mounted display 1000 may display an image through a plurality of display modules included in each of the plurality of display devices 100-1 to 100-16. Here, the image may be an image input from an external device (not shown) to one of the display apparatuses 100 in the wall-mounted display 1000, or may be an image previously stored in the wall-mounted display 1000.

In order for the plurality of display devices 100-1 to 100-16 of the wall-mounted display 1000 to display images, the plurality of display devices 100-1 to 100-16 may transmit image signals to each other. Here, the image signal may include a video signal, an audio signal, and a synchronization signal for synchronizing the plurality of display devices. Further, the plurality of display devices 100-1 to 100-16 may transmit not only an image signal but also a control signal for controlling the display devices, and the like.

Specifically, at least one display device 100 included in the wall-mounted display 1000 may simultaneously transmit an image signal to a plurality of display devices.

For example, the display apparatus 100-13 in fig. 1B may transmit the image signal to the display apparatus 100-9 and the display apparatus 100-14 at the same time. Also, the display apparatus 100-14 may transmit the image signal to the display apparatus 100-10 and the display apparatus 100-15.

In this way, each of the plurality of display devices 100-1 to 100-16 forming the wall-mounted display may transmit an image to a display device in the wall-mounted display, and a display device receiving the image may display the received image.

In this regard, fig. 1C is a diagram illustrating an image displayed by a display device in a wall-mounted display according to an embodiment.

The display apparatus 100 may display a portion of an image displayed on the wall-mounted display 1000 in consideration of the position of the display apparatus 100 in the wall-mounted display 1000.

For example, as shown in fig. 1C, if the wall-mounted display 1000 displays an image through a plurality of display devices, the display device 100 may display a lower left portion of the image displayed on the wall-mounted display 1000.

To this end, each of the plurality of display devices 100-1 to 100-16 in the wall-mounted display 1000 may have position information, such as coordinate information, of the display device in the wall-mounted display. In addition, the image signals transmitted to the plurality of display devices in the wall-mounted display 1000 may include location information of each of the plurality of display devices.

The display apparatus receiving the image signal including the location information of the plurality of display apparatuses 100 forming the wall-mounted display may display an image corresponding to the location of the display in consideration of the location information of the display apparatus.

Fig. 2 is a block diagram provided to explain a display apparatus according to an embodiment.

Referring to fig. 2, the display apparatus according to the embodiment may include a display module 110, a first input interface 120, a first output interface 130, a second output interface 140, and a processor 150.

The display module 110 is configured to display an image corresponding to an image signal received by the display apparatus 100.

The display device 100 may include a plurality of display modules.

The display module 110 may be implemented as an LED display module including inorganic light emitting diodes.

In particular, the display module 110 may be implemented as an LED display module including a plurality of LEDs in which sub-pixels of red, green, and blue LEDs are implemented as one pixel.

Here, the plurality of pixels may be arranged in the form of a matrix (e.g., M × N, where M and N are natural numbers). Specifically, the matrix may be in the form of the same arrangement (e.g., an arrangement where M is N, 16 × 16, 24 × 24, etc., where M and N are natural numbers), or may be in the form of a different arrangement (e.g., M where M and N are natural numbers).

Further, the LEDs of the display module according to the embodiment may be implemented as micro LEDs. Here, the micro LED is an LED having a size of about 5 to 100 micrometers, and refers to a small light emitting device emitting light without a color filter.

Accordingly, since the display module 110 is composed of the micro LEDs, the wall-mounted display 1000 according to the embodiment may be implemented without a bezel, and may display images seamlessly between display devices when displaying images.

However, such an LED display module is an example, and the display module may be implemented as a flat display panel such as a Liquid Crystal Panel (LCP), an organic LED (oled), an active matrix oled (amoled) panel, a Plasma Display Panel (PDP), and the like.

In the present disclosure, it is assumed that the display module according to the embodiment is an LED display module for convenience of explanation.

The first input interface 120 is a component that the display apparatus 100 receives an image signal.

Specifically, the first input interface 120 may receive an image signal from a display apparatus adjacent to the display apparatus 100 or an external device. Here, the external device may be an electronic apparatus (such as a media box, a server, etc.) capable of transmitting an image signal to a display apparatus forming a wall-mounted display.

The first input interface 120 may include a Digital Video Interface (DVI) that may receive a video signal or an audio signal, a Display Port (DP), a High Definition Multimedia Interface (HDMI), a component, and the like. Further, the first input interface 120 may include an input port for controlling the display apparatus and the like, for receiving a control signal for controlling the display apparatus 100. In addition, the first input interface 120 may include a detection port for checking connection with a peripheral display device, and may include various other input ports, if necessary.

The first input interface 120 may be connected to an adjacent display apparatus or an external device through a cable connected to the various ports described above. Here, the cable may be a DVI cable, a DP cable, or an HDMI cable, depending on the port. However, this is merely an example, and various cables may be connected to the first input interface 120.

Further, in some cases, the display device 100 may include multiple input interfaces. In other words, the display apparatus 100 may include the second input interface and the third input interface.

The first output interface 130 and the second output interface 140 are components of the display apparatus 100 that transmit image signals.

Specifically, the display apparatus 100 may transmit the image signal to a display apparatus adjacent to the display apparatus 100 through the first output interface 130 and the second output interface 140.

The first output interface 130 and the second output interface 140 may include a Digital Video Interface (DVI), a Display Port (DP), a High Definition Multimedia Interface (HDMI), a component, etc. in order to transmit a video signal or an audio signal. In addition, the first output interface 130 and the second output interface 140 may include an input port for controlling the display apparatus in order to transmit a control signal for controlling the display apparatus 100 to another display apparatus. In addition, the first output interface 130 and the second output interface 140 may include a detection port capable of checking connection with a peripheral display device, and may include various other output ports if necessary.

The first output interface 130 and the second output interface 140 may be connected to adjacent display apparatuses or external devices through cables connected to the various ports described above. Like the first input interface 120, the cables connected to the first output interface 130 and the second output interface 140 may be DVI cables, DP cables, or HDMI cables according to ports. However, this is merely an example, and various cables may be connected to the first output interface 130 and the second output interface 140.

In addition, the first output interface 130 and the second output interface 140 may be connected to different display devices in the wall-mounted display 1000. Accordingly, the display apparatus 100 may receive an image signal and simultaneously transmit it to a plurality of display apparatuses.

The first output interface 130 may be connected to a first display device arranged adjacent to a first side of the display device 100. In this case, the display apparatus 100 may transmit the image signal to the first display apparatus.

The second output interface 140 may be connected to a second display device arranged adjacent to a second side of the display device 100. In this case, the display apparatus 100 may transmit the image signal to the second display apparatus.

For example, if the first output interface 130 is located at a lower portion of the display apparatus 100, the first output interface 130 may transmit an image signal to a display apparatus disposed adjacent to the lower portion of the display apparatus 100. If the second output interface 140 is located at an upper portion of the display apparatus 100, the second output interface 140 may transmit an image signal to the display apparatus disposed adjacent to an upper port of the display apparatus 100, which will be described in detail with reference to fig. 3.

Further, in some cases, the display device 100 may include additional output interfaces. In other words, the display apparatus 100 may include a third output interface and a fourth output interface.

The processor 150 controls the overall operation of the display apparatus 100. To this end, the processor 150 may include one or more of a Central Processing Unit (CPU), an Application Processor (AP), or a Communication Processor (CP). Further, processor 150 may be implemented as a system on a chip (SoC).

The processor 150 may receive the image signal through the first input interface. As described above, the first input interface may be connected to an external device or an output interface of another display apparatus forming the wall-mounted display 1000.

In other words, the processor 150 may receive the image signal through the first input interface 120 connected to the external device, or may receive the image signal through the first input interface connected to the output interface of another display apparatus in the wall-mounted display 1000.

Upon receiving the image signal through the first input interface, the processor 150 may display an image corresponding to a position of the display apparatus 100 in the wall-mounted display 1000 through the plurality of display modules based on the received image signal.

Further, as described above, the image signal may include not only data related to an image displayed on the wall-mounted display 1000 but also position information of the plurality of display devices 100-1 to 100-16 forming the wall-mounted display 1000.

The processor 150 may extract an image signal corresponding to the position of the display apparatus 100 from the received image signal using the position information of the display apparatus 100 and display the corresponding image through the plurality of display modules.

The processor 150 may transmit the received image signal to a first display device and a second display device forming the wall-mounted display 1000 through a first output interface and a second output interface, respectively.

Specifically, the processor 150 may transmit the received image signal to a first display apparatus disposed adjacent to a first side of the display apparatus 100 through the first output interface 130, and may transmit the received image signal to a second display apparatus disposed adjacent to a second side of the display apparatus 100 through the second output interface 140.

To this end, a plurality of display devices forming the wall-mounted display 1000 are interconnected, and each display device may transmit/receive an image signal through a first input interface, a first output interface, and a second output interface of the display device.

Fig. 3 is a diagram provided to explain a connection structure between a display device and a transmission structure of an image signal in a wall-mounted display according to an embodiment.

In fig. 3, for convenience of explanation, a wall-mounted display 1000 is shown to include four display devices 100-1, 100-2, 100-3, and 100-4.

The display device 100 may be a display device disposed at an edge region in the wall-mounted display 1000. In other words, the display device 100 according to the embodiment may be one of four display devices 100-1, 100-2, 100-3, and 100-4. Further, this is merely an example, and the display apparatus 100 according to the embodiment may be arranged regardless of a position in the wall-mounted display 1000.

The processor 150-3 of the display apparatus 100-3 may receive an image signal from the external device 2000 through the first input interface 120-3, and the processor 150-3 may transmit the received image to the display apparatus 100-4 through the first output interface 130-3. In addition, the processor 150-3 may transmit the received image signal to the display apparatus 100-1 through the second output interface 140-3.

The processor 150-4 of the display device 100-4 may receive the image signal from the display device 100-3 through the first input interface 120-4. Here, the first input interface 120-4 of the display apparatus 100-4 may be connected to the first output interface 130-3 of the display apparatus 100-3.

The processor 150-4 may transmit the received image to the display apparatus 100-2 through the second output interface 140-4.

In addition, since there is no display device adjacent to the right side of the display device 100-4, the processor 150-4 may not output the image signal through the first output interface 130-4.

On the other hand, if there is a display device adjacent to the display device 100-4 on the right side of the display device 100-4, the processor 150-4 may transmit an image signal to the display device existing on the right side of the display device 100-4 through the first output interface 130-4, which will be described with reference to fig. 4.

The processor 150-1 of the display device 100-1 may receive an image signal from the display device 100-3 through the first input interface 120-1. Here, the first input interface 120-1 of the display apparatus 100-1 may be connected to the second output interface 140-3 of the display apparatus 100-3.

If there is a display device adjacent to the upper side of the display device 100-1, the processor 150-1 may transmit an image signal to a display device (not shown) adjacent to the upper side through the second output interface 140-1 as the processor 150-3.

However, as shown in fig. 3, if there is no display device adjacent to the display device 100-1 on the upper side of the display device 100-1, the processor 150-1 may transmit an image signal to the adjacent display device 100-2.

In this case, the image signal transmitted by the processor 150-1 through the second output interface 140-1 may be input to the display apparatus 100-2 through the second input interface 160-2 of the display apparatus 100-2.

In this regard, the display devices 100-1, 100-2, 100-3, and 100-4 may further include a second input interface 160-1, 160-2, 160-3, and 160-4 for redundancy of the display devices. In this case, the second input interface may be connected to other display devices 100-1, 100-2, 100-3, and 100-4 different from the display devices connected to the first input interfaces 120-1, 120-2, 120-3, and 120-4. In other words, the display devices 100-1, 100-2, 100-3, and 100-4 including the first input interfaces 120-1, 120-2, 120-3, and 120-4 and the second input interfaces 160-1, 160-2, 160-3, and 160-4 may receive image signals from a plurality of adjacent display devices. Here, the image signals input through the second input interfaces 160-1, 160-2, 160-3, and 160-4 may be the same as the image signals input through the first input interfaces 120-1, 120-2, 120-3, and 120-4.

If the display devices 100-1 and 100-2 are adjacent to the upper sides of the display devices 100-3 and 100-4, the processors 150-3 and 150-4 may receive image signals from the display devices 100-1 and 100-2 of the upper sides through the second input interfaces 160-3 and 160-4.

The processor 150-2 may receive an image signal from the display device 100-4 through the first input interface 120-2. In this case, the first input interface 120-2 of the display apparatus 100-2 may be connected to the second output interface 140-4 of the display apparatus 100-4.

As in the case of the display device 100-3, there is no display device adjacent to the upper side of the display device 100-2, and the received image may be transmitted to the display device 100-1 through the second output interface 140-2.

The image signal input through the second input interface 160-1 of the display apparatus 100-1 and the second input interface 160-2 of the display apparatus 100-2 may be transmitted to the display apparatuses 100-3 and 100-4 adjacent to the lower sides of the display apparatuses 100-1 and 100-2 through the first output interface 130-1 of the display apparatus 100-1 and the first output interface 130-2 of the display apparatus 100-2.

In short, the processor 150-3 may first receive an image signal from the external device 2000. Subsequently, the processor 150-3 may transmit the received image signals to the display apparatus 100-1 and the display apparatus 100-4, respectively.

In this case, the image signal transmitted from the display apparatus 100-3 to the display apparatus 100-1 may be sequentially transmitted to the display apparatus 100-2 and the display apparatus 100-4. The image signal transmitted from the display apparatus 100-3 to the display apparatus 100-4 may be sequentially transmitted to the display apparatus 100-2, the display apparatus 100-1, and the display apparatus 100-3.

In this way, the display apparatus can receive image signals from a plurality of display apparatuses. In this case, the image signal is an image signal transmitted by the display apparatus 100-3 receiving the image signal from the external device 2000, and thus, it may be the same image signal.

In other words, the wall-mounted display including the display device according to the embodiment may not transmit the same image signal a plurality of times for redundancy of the display device.

Further, in fig. 3, the second output interfaces 140-1, 140-2, 140-3, and 140-4 and the second input interfaces 160-1, 160-2, 160-3, and 160-4 are separately illustrated, but the second input interface and the second output interface may be implemented as one interface that performs an input/output function at the same time. The first input interfaces 120-1, 120-2, 120-3, and 120-4 and the first output interfaces 130-1, 130-2, 130-3, and 130-4 may also be implemented as one interface that performs input/output functions simultaneously.

The connection structure and the data transmission structure of the plurality of display devices of fig. 3 are only examples, and the connection structure and the data transmission structure of the display devices may vary between the display devices in a cable connection form.

Referring back to fig. 2, as described above, the processor 150 may receive the image signal through the first input interface 120 and the second input interface. If there is an error in the image signal received through the first input interface 120, the processor 150 may display an image corresponding to the position of the display apparatus 100 in the wall-mounted display 1000 through the plurality of display modules 110 based on the image signal received through the second input interface.

In this way, even if there is an error in the image signal received by the display apparatus 100, an image can be displayed using the redundant image signal, and thus, the stability of the wall-mounted display 1000 including the display apparatus 100 can be maintained.

Further, unlike the wall-mounted display 1000 of fig. 3, if a plurality of display apparatuses are arranged in one direction of the display apparatus 100, an image signal may be sequentially transmitted in the one direction.

In this regard, fig. 4 and 5 are diagrams provided to explain a wall-mounted display sequentially transmitting image signals according to an embodiment.

Referring to fig. 4 and 5, the wall-mounted display may include a total of 16 display devices of 4 in the horizontal direction and 4 in the vertical direction. However, this is merely an example, and in some cases, a wall-mounted display may include more display devices.

Also, for convenience of explanation, the first and second interfaces and the first and second output interfaces included in the display apparatus 100 will not be shown.

As described above in fig. 3, if the display apparatuses 100-13 receive the image signal from the external device 2000, the processor of the display apparatuses 100-13 may transmit the image signal to the display apparatuses 100-14 and 100-9.

In particular, the processor of the display device 100-13 may transmit the received image signal to the display device 100-14 disposed adjacent to the first side of the display device 100-13 through the first output interface of the display device 100-13. Further, the processor of the display apparatus 100-13 may transmit the received image signal to the display apparatus 100-9 arranged adjacent to the second side of the display apparatus 100-13 through the second output interface of the display apparatus 100-13.

The image signals transmitted to the display apparatuses 100-14 through the first output interfaces of the display apparatuses 100-13 may be sequentially transmitted to at least one display apparatus arranged in the first direction of the display apparatuses 100-14. For example, the image signal may be sequentially transmitted to the display devices 100-15 and 100-16 after passing through the display devices 100-14.

To this end, the display apparatus 100-14 receiving the image signal from the display apparatus 100-13 transmits the received image signal to the display apparatus 100-15, and the display apparatus 100-15 again transmits the received image signal to the display apparatus 100-16.

The image signals transmitted to the display apparatus 100-9 through the second output interface of the display apparatus 100-13 may be sequentially transmitted to at least one display apparatus arranged in the second direction of the display apparatus 100-13. For example, the image signal received by the display apparatus 100-13 may be sequentially transmitted to the display apparatus 100-5 and the display apparatus 100-1 after passing through the display apparatus 100-9.

To this end, the display apparatus 100-9 receiving the image signal from the display apparatus 100-13 may transmit the received image signal to the display apparatus 100-5, and the display apparatus 100-5 may transmit the received image signal to the display apparatus 100-1 again.

In addition, the display apparatus 100-14 receiving the image signal also transmits the image signal to the display apparatus 100-10. In this case, the image signal is sequentially transmitted to the display apparatus 100-10, the display apparatus 100-6, and the display apparatus 100-2. Also, the image signals may be sequentially transmitted from the display devices 100-15 and 100-16 in the column direction. In other words, the image signals may be transmitted from the display devices 100-13, 100-14, 100-15, and 100-16 in the direction of solid arrows in the column direction.

Further, as described above with reference to fig. 3, the display devices 100-1, 100-2, 100-3, and 100-4 having no display device adjacent to the upper side may transmit the image signal to the adjacent display devices.

Specifically, the display apparatus 100-1 may transmit an image signal to the display apparatus 100-2, and the display apparatus 100-2 may transmit the received image signal to the display apparatus 100-6. In addition, the display apparatus 100-2 may transmit an image signal to the display apparatus 100-1, and the display apparatus 100-1 may transmit the received image signal to the display apparatus 100-5. This is the same for the display device 100-3 and the display device 100-4. In other words, the image signals may be transmitted from the display devices 100-1, 100-2, 100-3, and 100-4 in the direction of the dotted arrow in the column direction.

Further, referring to fig. 5, the display apparatus 100-13 receiving the image signal from the external device 2000 transmits the image signal to the display apparatus 100-9 and the display apparatus 100-14, and the received image signal is sequentially transmitted to the display apparatus 100-9, the display apparatus 100-5, and the display apparatus 100-1, which is the same as the case of fig. 4.

However, referring to fig. 5, the first output interfaces of the display devices 100-1, 100-5, 100-9, and 100-13 are connected to the display devices 100-2, 100-6, 100-10, and 100-14, respectively, and may transmit image signals to the display devices 100-2, 100-6, 100-10, and 100-14.

When the plurality of display apparatuses 100 in the wall-mounted display transmit the image signals by the above-described method, the image signals may be transmitted from the display apparatuses 100-1, 100-5, 100-9, and 100-13 in the direction of solid arrows in the row direction. Further, image signals may be transmitted from the display devices 100-4, 100-8, 100-12, and 100-16 again in the direction of the dotted arrows in the row direction.

Since the transmission structure of the image signal of fig. 5 is the same as that of fig. 4, differing only in direction, a detailed description thereof will be omitted.

In addition, the wall mounted display 1000 according to an embodiment may add a display device.

Fig. 6 is a diagram illustrating a case where a new display device is added to a wall-mounted display 1000 including a display device according to an embodiment, so that the wall-mounted display 1000 is expanded.

If a new display device is added to the wall-mounted display and the first input interface 120 is connected to the output interface of the added display device, the processor 150 may receive an image signal from the added display device through the first input interface.

For example, if the display apparatuses 100-17, 100-18, 100-19, and 100-20 are added to the left side of the wall-mounted display (i.e., the left side of the display apparatuses 100-13), the first input interface of the display apparatuses 100-13 may be connected to the first output interface of the display apparatuses 100-20 instead of the external device 2000.

In this case, the external device 2000 may transmit the image signal to the display apparatuses 100 to 20, and the display apparatuses 100 to 20 may transmit the image signal to the display apparatuses 100 to 19 and 100 to 13. In addition, the display apparatus 100-13 may receive an image signal from the display apparatus 100-20 through the first input interface of the display apparatus 100-13.

Further, if a new display device is added to the wall-mounted display and the second output interface 140 is added to the input interface of the added display device, the processor 150 may transmit an image signal to the added display device through the second output interface 140.

For example, if the display devices 100-21, 100-22, 100-23, and 100-24 are added to the upper side of the wall-mounted display (i.e., the display devices 100-1, 100-2, 100-3, and 100-4), the second output interface of the display devices 100-1, 100-2, 100-3, and 100-4 may be connected to the first input interface of the display devices 100-21, 100-22, 100-23, and 100-24. In this case, the image signal may be transmitted to each of the display devices 100-21, 100-22, 100-23, and 100-24 through the second output interface included in each of the display devices 100-1, 100-2, 100-3, and 100-4.

The same is true when display devices 100-25, 100-26, 100-27, and 100-28 are added to the right side of the wall mounted display (i.e., display devices 100-4, 100-8, 100-12, and 100-16).

As described above, if a display device is newly added to the wall-mounted display 1000 including the display device 100, only the connection of the display device connected to the added display device needs to be readjusted, and the connection between the display devices in the existing wall-mounted display 1000 does not need to be readjusted. Accordingly, the scalability of a wall-mounted display including a display device can be improved.

In addition, the wall-mounted display apparatus according to the embodiment may have various forms.

In this regard, fig. 7 and 8 are diagrams provided to explain wall-mounted displays having various forms beyond conventional rectangular wall-mounted displays. In addition, fig. 7 and 8 illustrate a Ψ -shaped wall-mounted display. However, the shape of the wall-mounted display is not limited thereto, and may have various forms.

The display apparatus 100-4 forming the wall-mounted display 1000, which receives the image signal from the external device 2000, may transmit the image signal to the display apparatus 100-3 and the display apparatus 100-5.

In this case, the image signal may be sequentially transmitted to the display apparatus 100-3, the display apparatus 100-2, and the display apparatus 100-1.

Further, the image signal may be sequentially transmitted to the display apparatus 100-5, the display apparatus 100-6, the display apparatus 100-10, the display apparatus 100-11, the display apparatus 100-12, and the display apparatus 100-16.

In this case, the display apparatus 100-10 may transmit the image signal to the display apparatus 100-11 and the display apparatus 100-9. The image signal transmitted from the display apparatus 100-10 to the display apparatus 100-9 may be sequentially transmitted to the display apparatus 100-8 and the display apparatus 100-7.

Further, the image signal may be sequentially transmitted to a plurality of display devices in the wall-mounted display as shown in fig. 7, but this is merely an example.

In other words, as shown in fig. 8, the image signals may not be sequentially transmitted.

For example, referring to fig. 8, although the display devices 100-10, 100-9, 100-8, and 100-7 are sequentially arranged in the wall-mounted display 1000, image signals may be transmitted in the order of the display devices 100-10, 100-9, 100-7, and 100-8 regardless of the physical arrangement of the display devices.

In this way, the display device 100 includes a plurality of output interfaces, and images can be simultaneously transmitted to a plurality of display devices, and therefore, the structure of transmitting image signals to a plurality of display devices can be diversified. In addition, the shape of a wall-mounted display including the display apparatus 100 may be diversified.

Further, fig. 9 is a block diagram provided to explain a wall-mounted display according to an embodiment.

Referring to fig. 9, a wall-mounted display 1000 according to an embodiment may include a first display device 100-1 and second through nth display devices 100-2 through 100-n, a memory 200, an interface 300, a communicator 400, a microphone 500, a speaker 600, a manipulator 700, and a processor 800. Hereinafter, portions overlapping with the above description will be omitted or summarized.

The memory 200 may store an Operating System (OS) for controlling overall operations of elements of the wall-mounted display 1000 and commands or data related to the elements of the wall-mounted display 1000.

Thus, the processor 800 may control a plurality of hardware elements or software elements of the wall-mounted display 1000 using various commands or data stored in the memory 200, load and process commands or data received from at least one of the other elements onto the volatile memory, and store various data in the non-volatile memory.

In addition, the memory 200 may be implemented as various types of storage media. For example, the memory 200 may be implemented as a storage device such as a Read Only Memory (ROM), a Programmable Read Only Memory (PROM), an Erasable Programmable Read Only Memory (EPROM), a non-volatile memory element such as a flash memory or a volatile memory element such as a Random Access Memory (RAM), a hard disk, an optical disk, or the like.

The communicator 400 may transmit/receive various data by performing communication with an external device (not shown). For example, the communicator 400 may perform communication with an external device such as a smart phone or the like to receive a background image, a signal for controlling the wall-mounted display 1000, or a signal for controlling the external device. To this end, the communicator 400 may include a wireless communication chip, a Wi-Fi chip, a Bluetooth chip, and the like.

The microphone 500 may receive a user voice. Here, the user voice may be a voice for performing a specific function of the wall-mounted display 1000.

Upon receiving a user voice for performing a specific function through the microphone 500, the processor 800 may convert the user voice into a digital signal through a voice to text (STT) algorithm and provide response information corresponding to the user voice. Here, the response information may be not only received through an external server but also generated by the wall-mounted display 1000 itself.

The speaker 600 may output various audio signals on which various processes such as decoding, amplification, and noise filtering are performed by an audio processor (not shown). In addition, the speaker 600 may output various notification sounds or voice messages. According to an embodiment, the speaker 600 may output an audio signal when the resolution of an image to be displayed on the wall-mounted display 1000 is changed.

The manipulator 700 may be implemented as a touch screen, a touch pad, buttons, a keypad, and the like.

The processor 800 controls the overall operation of the wall-mounted display 1000.

Specifically, the processor 800 may control hardware components or software components connected to the processor 800 by driving an operating system or an application program, and may perform various data processing and operations. Further, the processor 800 may load a command or data received from at least one of the other components onto the volatile memory and process the command or data received from the at least one of the other components and store various data in the non-volatile memory.

To this end, the processor 800 may be implemented as a general-purpose processor (e.g., a CPU or an application processor) capable of performing corresponding operations by executing a special-purpose processor (e.g., an embedded processor) or one or more software programs stored in a memory device.

The processor 800 may control the processor (or the T controller) included in each of the plurality of display apparatuses to display an image received from an external device (not shown) through each of the plurality of display modules, or control the processor included in each of the plurality of display apparatuses to display a pre-stored image through each of the plurality of display modules.

In addition, the wall-mounted display 1000 may further include a USB port connectable to a USB connector, various external input ports for connecting to various external terminals such as an earphone, a mouse, a LAN, etc., a Digital Multimedia Broadcasting (DMB) chip for receiving and processing DMB signals, etc.

In addition, the wall-mounted display 1000 may further include a broadcast receiver (not shown) receiving a broadcast signal from a broadcasting station or a satellite through wire or wirelessly, a signal divider (not shown) dividing the broadcast signal received from the broadcast receiver (not shown) into an image signal, an audio signal, and an additional information signal, and an a/V processor (not shown) performing video decoding and video scaling on the image signal and performing audio decoding on the audio signal.

Fig. 10 is a flowchart provided to explain a control method of a display apparatus according to an embodiment.

The display apparatus forming a wall-mounted display according to an embodiment may receive an image signal through a first input interface (S1010).

In this case, the image signal may be received through the first input interface of the display apparatus connected to the external device, or may be received through the first input interface connected to the output interface of another display apparatus forming the wall-mounted display.

Here, the display device may be disposed on an edge area of the wall-mounted display.

In addition, an image corresponding to a position of the display apparatus in the wall-mounted display may be displayed through a plurality of display modules based on the received image signal (S1020).

The received image signals may be transmitted to first and second display apparatuses forming a wall-mounted display through first and second output interfaces, respectively (S1030).

Specifically, the electronic apparatus may transmit the received image signal to a first display device disposed adjacent to a first side of the display device through the first output interface, and may transmit the received image signal to a second display device disposed adjacent to a second side of the display device through the second output interface.

In this case, the image transmitted to the first display device through the first output interface may be sequentially transmitted to the at least one display device disposed in the first direction of the first display device, and the image transmitted to the second display device through the second output interface may be sequentially transmitted to the at least one display device disposed in the second direction of the second housing.

Further, if a new display device is added to the wall-mounted display and the first input interface is connected to the output interface of the added display device, an image signal may be received from the added display device through the first input interface.

Further, if a new display device is added to the wall-mounted display and the second output interface is connected to the input interface of the added display device, the image signal may be transmitted to the added display device through the second output interface.

In addition, the electronic device can receive the image signal through the second input interface.

Specifically, if there is an error in the image signal received through the first input interface, an image corresponding to the position of the display apparatus in the wall-mounted display may be displayed through the plurality of display modules based on the image signal received through the second input interface.

Further, a non-transitory computer readable medium may be provided, in which a program for sequentially performing a control method of a display apparatus forming a wall-mounted display according to an embodiment is stored.

Non-transitory computer-readable media refer to media that store data semi-permanently and that are readable by a machine, and not media that store data for short periods of time (such as registers, caches, and memory). Specifically, the various applications or programs described above may be stored and set in a CD, DVD, hard disk, blu-ray disc, USB, memory card, ROM, or the like.

While the embodiments of the present disclosure have been shown and described with reference to the drawings, the embodiments are provided for the purpose of illustration, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments may be made from the present disclosure. Therefore, the true technical scope of the present disclosure is defined by the technical spirit of the appended claims.
