The LED full-color display screen is widely used in many occasions at present, can be freely spliced, is suitable for large screens of different sizes to display seamlessly, is used for displaying advertisements and publicity phrases such as video images, can be suitable for various occasions, and is deeply popular with various users. With the wider and wider use of human-computer interaction scenes, 3D films can be watched on large LED display screens more and more. An LED display system for playing 2D video is upgraded to an LED display system supporting 3D video playing, which is an industry trend.

Detailed Description

The following description of the embodiments of the present application is provided by way of specific examples, and other advantages and effects of the present application will be readily apparent to those skilled in the art from the disclosure herein. The present application is capable of other and different embodiments and its several details are capable of modifications and/or changes in various respects, all without departing from the spirit of the present application. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only schematic and illustrate the basic idea of the present application, and although the drawings only show the components related to the present application and are not drawn according to the number, shape and size of the components in actual implementation, the type, quantity and proportion of the components in actual implementation may be changed at will, and the layout of the components may be more complex.

At present, 3D display schemes are various, and an active shutter type 3D display scheme is generally adopted, a 120Hz left eye picture and a 120Hz right eye picture are alternately displayed on an LED display screen, and active shutter glasses switch shutters at 120Hz, so that left and right eyes can see corresponding left and right eye pictures, and thus, a stereoscopic 3D picture can be seen. The existing LED screen display system supporting the 3D function adopts the technical scheme that an upper computer or a sending card directly sends a left eye picture and a right eye picture to a scanning card at the frequency of 120Hz, the scanning card caches the left eye picture and the right eye picture, then the left eye picture and the right eye picture are alternately sent to an LED display screen, and the display screen alternately displays the pictures corresponding to the left eye and the right eye. But this way of sending directly to the scan card at 120Hz increases the transmission bandwidth considerably.

In addition, as mentioned in the system of application No. CN201520296835.6 for realizing 3D display on LED display screen: the left-eye data and the right-eye data are fused into 3D video data of 100HZ or 120HZ and transmitted, but the number of video controllers required in such a 3D display mode is twice that of 2D video.

In order to solve the above problems, the present application provides a method, an apparatus, a device, a system, and a medium for 3D display on an LED display screen, which do not require an increase in the number of transmitting cards and transmission bandwidth compared to the prior art, and can efficiently utilize the storage space of a conventional 3D display system.

The LED display screen 3D display method is applied to an LED display screen system comprising a sending card and a scanning card, wherein the sending card in the LED display screen mainly packs image information and then sends the packed image information to the scanning card (or a receiving card), and the scanning card is used for unpacking and then carrying out image processing.

Fig. 1 is a schematic flow chart of a 3D display method of an LED display screen according to an embodiment of the present invention. As shown, the method comprises:

step S101: acquiring 2D video data, and enabling a sending card to send the 2D video data to a scanning card at an image display frame rate of 50Hz or 60 Hz; wherein the 2D video data comprises right eye video data and left eye video data.

The left-eye video data generally refers to image data for displaying on an LED display screen for the left eye in the 3D field, and correspondingly, the right-eye video data refers to image data for displaying on the LED display screen for the right eye, and then the shutter is switched at a frequency of 120hz by means of active shutter glasses, so that the left and right eyes can see corresponding left and right eye pictures, and thus, a stereoscopic 3D picture can be seen.

It should be noted that the image display frame rate of 50Hz or 60Hz is a frequency common in the art for synthesizing 3D video, but the application is not limited to these two frequencies, and the frequencies below 50Hz, or between 50Hz and 60Hz, or above 60Hz also belong to the protection scope of the application; accordingly, the synthesized 3D video frequency is not clipped to 100Hz or 120Hz, and frequencies below 100Hz, or between 50Hz and 60Hz, or above 120Hz are also within the scope of the present application.

Step S102: order the scanning cardSecond orSequentially and alternately storing the right eye video data and the left eye video data into a storage space within seconds; and after buffering the right eye video data or the next one of the left eye video dataSecond orWithin a secondAnd transmitting right eye video data or left eye video data with an image display frame rate of 100Hz or 120Hz to a display screen within the time so as to watch the 3D picture through active shutter glasses.

Compared with the prior art, the method and the device have the advantages that the technical effect of the storage space of the conventional 3D display system can be effectively utilized without increasing the number of sending cards and the transmission bandwidth, and the technical means in the step S102 is mainly embodied.

First embodiment

The specific steps of the present embodiment corresponding to the step S102 include the following, which can refer to the example table corresponding to the process of the present method shown in table 1 below. In addition, in the present embodiment, 2D video data is taken as an example of image display frame rates of 60Hz and 120Hz, and correspondinglySecond andtime in seconds is an example.

Table 1 example table corresponding to the flow of the method of the present application

1) The scanning card is at time t1 (Second) stores the first picture R1 of the right-eye video data into the first storage space B1; preferably, the SDRAM memory space of the scan card includes: the storage device comprises a first storage space, a second storage space and a third storage space.

2) The scan card is at time t2 (next)Second) stores the first picture L1 of the left-eye video data into the second storage space B2; wherein, during the latter half of t2 (i.e., during the second half of t 2)After secondSecond), the scanning card also reads a first picture R1 of the right-eye video data of the first storage space B1 and sends the first picture to the display screen; here, the image display frame rate of the first picture R1 of the right-eye video data sent to the display screen here is 120 Hz.

3) The scan card is at t3 (next to next)Seconds) to store the second picture R2 of the right-eye video data into the third storage space B3; wherein during the first half of t3 (i.e., during the first half of t 3)First in secondsSecond), the scanning card also reads a first picture L1 of the left eye video data of the second storage space B2 and sends the first picture to a display screen; the latter half of time (i.e. t 3)After secondSecond), the scanning card also reads a first picture R0 of the right-eye video data of the first storage space B1 and sends the first picture to the display screen;

4) the scan card stores the second picture L2 of the left-eye video data into the first storage space B1 within t4 to overwrite the first picture R1 of the right-eye video data; during the first half of t4, the scanning card simultaneously reads the first picture L1 of the left-eye video data in the second storage space B2, stores the first picture and sends the first picture to the display screen; during the latter half of t4, the scanner card also reads the second picture R2 of the video data for the right eye in the third storage space B3 and sends it to the display.

In one embodiment of the present application, it is understood that only 120Hz is illustrated in this embodiment, and in this application, the embodiment is described in the followingEach picture of the right-eye video data or the left-eye video data sent to the display screen within time is 100Hz or 120 Hz.

In an embodiment of the present application, the first frame R1 of the right-eye video data is transmitted twice and the first frame L1 of the left-eye video data is transmitted twice to form a complete first frame of the 3D video data.

In order to clearly understand the technical effects brought by the steps adopted in the present application, the present application further exemplifies example tables of flows corresponding to two prior art schemes, so as to provide a visual comparison with the schemes described in the present application.

Second embodiment

The technical scheme exemplified in the embodiment has the characteristics that: the sending card transmits the 3D video with the frame changing frequency of 60Hz images to the scanning card; the scanning card buffers the 60Hz video and then alternately sends the left eye picture and the right eye picture to the LED display screen at the frequency of 120 Hz. Thus, the amount of video data sent by the sending card to the scanning card is unchanged compared with the 2D video with normal 60Hz transmission, namely the transmission bandwidth is not increased. But the storage space on the scan card takes up more than in conventional 3D display systems. An example table of the process flow of the second embodiment is shown in table 2 below. In addition, in the present embodiment, the 2D video data is still exemplified by the image display frame rates of 60Hz and 120 Hz.

Table 2 example table corresponding to the flow of the method of the second embodiment

As can be seen from table 2, although the second embodiment is also to transmit 3D video of 60Hz image framing frequency to the scan card; the scanning card buffers 60Hz video and then alternately sends left and right eye pictures to the LED display screen at the frequency of 120Hz, however, 3D display of a complete picture is completed, and the storage space of the scanning card is increased by one storage space B4 compared with that of Table 1.

This is because, during time t3 of table 2, R1 and L1, which need to be transmitted for the second time, are not yet completed, and therefore, during time t4, a storage space of B4 is also needed to store new L2.

In table 1, because the task of sending R1 for the second time is completed within time t3 due to the offset of sending time, R1 may not be reserved in the storage space, and thus new L2 may be stored in storage space B1 in a manner of replacing R1 within time t 4. And because the R0 is buffered within the time t2, the condition of sending to the display screen is met, and therefore the buffered R0 is allowed to be sent to the display screen within the time t 2.

Note that, in the present application, the reason why the transmission of R0 to the display screen is set in the latter half of t2 is that: if the transmission R0 is set in the first half of t2, the second half of t2 cannot transmit L0 data, so that L0 is buffering during the whole time of t2, and cannot transmit L0 to the display screen when the buffering is not completed. Thus, the present application advances the R0 data by halfSecond (i.e. theSeconds) is not easily imaginable to the skilled person in comparison with the second embodiment.

Compared with the method shown in the table 2, the method does not occupy more memory space of the scanning card, and can realize the efficient utilization of the memory space of the conventional 3D display system. When an LED display system which is about to play 2D video is upgraded to an LED display system which supports 3D video playing, the number of sending cards is increased along with the original number of sending cards, the number of wires is not increased, the number of wires is correspondingly reduced, and the reduction of the number of wires means the reduction of failure rate.

Third embodiment

The prior art scheme exemplified in this embodiment has the following features: the upper computer or the sending card directly sends the left eye picture and the right eye picture to the scanning card at the frequency of 120Hz, the scanning card caches the left eye picture and the right eye picture, then the left eye picture and the right eye picture are alternately sent to the LED display screen, and the display screen alternately displays the pictures corresponding to the left eye and the right eye. That is, compared with normal 2D video playing, the number of sending cards is doubled, the data transmission amount is doubled accordingly, that is, a transmission line is doubled, so that the cost of the whole system is increased greatly.

An example table of the process flow of the second embodiment is shown in table 3 below. In the present embodiment, 2D video data is taken as an example at an image display frame rate of 120 Hz.

Table 3 shows an example of a flow chart of the method according to the third embodiment

As can be seen from table 3, the third embodiment adopts a manner of directly transmitting 120Hz video data, which requires 1 times more data transmission amount compared to table 1 or 2D video; and the storage space is only used for B0 and B1, but the storage space is left and is not used efficiently. Not only has high cost but also has low space utilization rate.

To sum up, the method of the present application not only realizes that the sending card transmits the video at 60Hz, and plays the 3D video at the image display frame rate of 120Hz after the card is scanned for buffering, but also can save a storage space. In addition, the storage space can be efficiently utilized.

Fig. 2 is a schematic block diagram of an LED screen 3D display device according to an embodiment of the present invention. As shown, the apparatus 200 includes:

a sending module 201, configured to obtain 2D video data, and enable a sending card to send the 2D video data to a scanning card at an image display frame rate of 50Hz or 60 Hz; wherein the 2D video data comprises right eye video data and left eye video data;
