The application relates to the technical field of display, in particular to a display panel and a display device.

Background

With the development of liquid crystal display technology, especially the development of full-screen technology, most manufacturers open holes in the backlight module of the display device to allow the cameras under the screen to be correspondingly placed, and thereby receive incident light from the external environment.

However, as shown in fig. 1, the panel body 500 of the display panel has a large number of metal traces 501, and the backlight 601 in the backlight module 600, which irradiates on the metal traces 501, is reflected to the under-screen camera 700 through the opening 602 of the backlight module 600, which affects the shooting effect of the under-screen camera 700. In the prior art, the light-shielding tape 800 is attached between the panel body 500 and the backlight module 600 to avoid reflection, but the substrate 502 attached to the light-shielding tape 800 in the panel body 500 has a certain thickness, and if the light-shielding tape 800 is narrow, the backlight 601 still irradiates the metal wire 501 through the substrate 502 to cause reflection, which affects the shooting effect of the under-screen camera 700.

The present application is further described below with reference to the accompanying drawings and examples.

Fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the present invention.

The display panel provided by the embodiment of the invention comprises a backlight module 1 and a panel main body 2, wherein the panel main body 2 is positioned on the backlight module 1.

The backlight module 1 includes a backlight unit 11 and a light source assembly 12. The backlight unit 11 is provided with a light transmitting portion 13, and the light transmitting portion 13 penetrates the backlight unit 11. The light-transmitting portion 13 may be a backlight hole, i.e., a backlight hole penetrating the backlight unit 11, and the backlight hole may be filled with a light-transmitting material. The backlight hole 13 may be a circular hole, and the light-transmitting material may be organic glass (PMMA). The panel main body 2 includes a light transmission region 200, and the light transmission portion 13 corresponds to the position of the light transmission region 200, that is, an orthographic projection of the light transmission portion 13 on the panel main body 2 completely coincides with the light transmission region 200. Through setting up light-transmitting area 200 and printing opacity portion 13, can increase display panel's luminousness, guarantee that more external light gets into display panel's bottom (the one side that backlight unit 11 deviates from panel main part 2 promptly) to improve display panel bottom camera shooting component's shooting effect.

Specifically, as shown in fig. 3, the backlight unit 11 may include a reflection sheet 112, a light guide plate 113, a diffusion sheet 114, a lower light-adding sheet 115, and an upper light-adding sheet 116, which are sequentially disposed. The reflective sheet 112 may be disposed on a back plate (not shown), the light guide plate 113 is disposed on the reflective sheet 112, the diffusion sheet 114 is disposed on the light guide plate 113, the lower brightness enhancement sheet 115 is disposed on the diffusion sheet 114, the upper brightness enhancement sheet 116 is disposed on the lower brightness enhancement sheet 115, and the panel body 2 may be disposed on the upper brightness enhancement sheet 116. The diffusion sheet 114 is used for diffusing light to provide a uniform surface light source, and the lower brightness enhancement sheet 115 and the upper brightness enhancement sheet 116 are used for enhancing the brightness of the light source. The light-transmitting portion 13 sequentially penetrates the reflection sheet 112, the light guide plate 113, the diffusion sheet 114, the lower light-adding sheet 115, and the upper light-adding sheet 116.

The light source assembly 12 serves to supply light to the panel main body 2 through the backlight unit 11. Specifically, the light source assembly 12 may include a first light source 121. The first light source 121 is located on the periphery of the backlight unit 11, and the first light source 121 may be disposed opposite to the light guide plate 113, so that the first light source 121 provides a uniform light source to the panel body 2 through the light guide plate 113. However, since the light-transmitting portion 13 penetrates the light guide plate 113, the first light source 121 cannot provide light to the light-transmitting region 200 corresponding to the light-transmitting portion 13, and thus the light-transmitting region 200 corresponding to the light-transmitting portion 13 cannot display normally. In order to ensure the normal display of the display panel, the light source assembly 12 may further include a second light source 122, and the second light source 122 may be located at a side of the backlight unit 11 facing away from the panel body 2, so that the second light source 122 may provide light to the light-transmitting region 200 of the panel body 2 through the light-transmitting portion 13 in the backlight unit 11.

Specifically, the second light source 122 may correspond to the position of the light-transmitting portion 13, that is, the orthographic projection of the second light source 122 on the backlight unit 11 is located in the light-transmitting portion 13, and the second light source 122 may be a transparent light source, so as to ensure that external light enters the bottom of the display panel through the second light source 122 when the camera module at the bottom of the display panel performs shooting, and the second light source 122 provides light to the light-transmitting area 200 of the panel main body 2 through the light-transmitting portion 13 when the display panel normally displays. The second light source 122 may also be located outside the light-transmitting portion 13, that is, the orthographic projection of the second light source 122 on the backlight unit 11 is located outside the light-transmitting portion 13, and by arranging a light guiding ring (not shown in the figure) between the second light source 122 and the backlight unit 11, the light beam emitted by the second light source 122 can enter the light-transmitting portion 13 through the light guiding ring, and then enter the light-transmitting area 200 of the panel main body 2 through the light-transmitting portion 13, and meanwhile, the arrangement of the second light source 122 does not affect the bottom of the display panel to receive external light.

As shown in fig. 2, the panel main body 2 includes a substrate 21, a light shielding layer 22, and metal wirings 23. The substrate 21 is close to one side of the backlight unit 11, the light shielding layer 22 is located at one side of the substrate 21 departing from the backlight unit 11, the metal wiring 23 is located at one side of the light shielding layer 22 departing from the substrate 21, namely, the substrate 21 is located between the backlight unit 11 and the light shielding layer 22, the light shielding layer 22 is located between the substrate 21 and the metal wiring 23, and the light shielding layer 22 shields the metal wiring 23. The substrate 21 may be a glass substrate, the metal wire 23 may be a data line, a signal line, or the like, and the metal wire 23 may be made of molybdenum Mo, titanium Ti, aluminum Al, or the like.

Since the reflectivity of the metal trace 23 is about 50%, the light beam irradiated onto the metal trace 23 is easily reflected to the bottom of the display panel through the light-transmitting portion 13, which affects the shooting effect of the camera module at the bottom of the display panel, the present embodiment thus provides the light-shielding layer 22 between the substrate 21 of the panel main body 2 and the metal wirings 23, and in the direction of the backlight module 1 pointing to the panel body 2, the light shielding layer 22 covers the metal traces 23, the light beam entering the panel main body 2 can be effectively prevented from being reflected to the bottom of the display panel through the metal wiring 23, the shooting effect of the camera component at the bottom of the display panel is improved, and the light shielding layer 22 is positioned between the substrate 21 and the metal wiring 23, i.e., the light-shielding layer 22 is close to the metal traces 23, so that the area covered by the light-shielding layer 22 can be sufficiently small, the light beam can be prevented from being reflected to the bottom of the display panel through the metal trace 23, so that the display effect of the display panel is not affected by the light shielding layer 22.

The panel main body 2 includes a color film substrate 2a and an array substrate 2b which are arranged oppositely, and the substrate 21, the light shielding layer 22 and the metal trace 23 are film layers in the color film substrate 2a and the array substrate 2 b.

In one embodiment, as shown in fig. 2, the color filter substrate 2a is located on the backlight unit 11, and the array substrate 2b is located on the color filter substrate 2a, that is, the color filter substrate 2a is located between the backlight unit 11 and the array substrate 2 b. The substrate 21 and the light-shielding layer 22 are located in the color film substrate 2a, and the metal trace 23 is located in the array substrate 2b, that is, the color film substrate 2a includes the substrate 21 and the light-shielding layer 22, the substrate 21 is close to one side of the backlight unit 11, the light-shielding layer 22 is located on one side of the substrate 21 away from the backlight unit 11, and the array substrate 2b includes the metal trace 23. The array substrate 2b may further include a substrate 27, the substrate 27 is located on a side of the metal trace 23 away from the color filter substrate 2a, and the substrate 27 may be a glass substrate.

The color filter substrate 2a further includes a plurality of color resistors 24 arranged at intervals, the light-shielding layer 22 includes a plurality of light-shielding blocks 211, and each color resistor 24 is located between two corresponding light-shielding blocks 211. The light shielding block 211 may be a black matrix. In this embodiment, the light-shielding blocks 211 around the color resistors 24 are used as light-shielding layers, which can avoid adding extra light-shielding layers in the color film substrate 2a, so that the light-shielding layers 22 can not only separate the adjacent color resistors 24 to prevent light leakage or color mixing, but also prevent light beams from being reflected to the bottom of the display panel through the metal traces 23.

The distribution density of the light shielding blocks 211 can be adjusted according to the route of the light beam reflected to the light transmitting portion 13 through the metal trace 23, that is, the distribution density of the light shielding blocks 211 in different areas of the panel main body 2 can be different.

Specifically, the panel body 2 may further include a display area 300 located outside the light transmission area 200, i.e., an area other than the light transmission area 200 may be the display area 300. The display region 300 may include a first sub-display region 301 and a second sub-display region 302, the first sub-display region 301 being disposed adjacent to the light-transmitting region 200, and the first sub-display region 301 being disposed around the light-transmitting region 200. The second sub-display area 302 is located outside the first sub-display area 301, that is, the other display areas except the first sub-display area 301 may be the second sub-display area 302. Wherein, as shown in fig. 4, a length D1 of the first sub-display region 301 in a direction a toward the center O of the light-transmitting region 200 is less than a length D2 of the second sub-display region 302 in the direction a toward the center O of the light-transmitting region 200.

The light beam entering the panel body 2 through the first sub-display area 301 can be reflected to the bottom of the display panel through the metal trace 23, so that the density of the light-shielding blocks 221 in the first sub-display area 301 can be increased on the basis of not affecting the display effect of the display panel, and the density of the light-shielding blocks 211 in the first sub-display area 301 is maximized, that is, the density of the light-shielding blocks 211 in the first sub-display area 301 is greater than that of the light-shielding blocks 211 in the light-transmitting area 200, and the density of the light-shielding blocks 211 in the first sub-display area 301 is greater than that of the light-shielding blocks 211 in the second sub-display area 302, so that the light beam entering the panel body 2 through the first sub-display area 301 is prevented from being irradiated onto the metal trace 23, and the light beam is prevented from being reflected to the bottom of the display panel through the metal trace 23.

The density of the light-shielding blocks 211 in the light-transmitting area 200 may be equal to the density of the light-shielding blocks 211 in the second sub-display area 302, or the density of the light-shielding blocks 211 in the light-transmitting area 200 may be less than the density of the light-shielding blocks 211 in the second sub-display area 302, or the density of the light-shielding blocks 211 in a partial area in the light-transmitting area 200 may be equal to the density of the light-shielding blocks 211 in the second sub-display area 302, and the density of the light-shielding blocks 211 in another partial area in the light-transmitting area 201 may be less than the density of the light-shielding blocks 211 in the second sub-display area 302.

In order to further increase the light transmittance of the light-transmitting area 200, improve the photographing effect of the bottom of the display panel, and reduce the density of the light-shielding blocks 211 in the light-transmitting area 200, the density of the light-shielding blocks 211 in the light-transmitting area 200 is minimized, that is, the density of the light-shielding blocks 211 in the light-transmitting area 200 is smaller than the density of the light-shielding blocks in the second sub-display area 302.

Specifically, as shown in fig. 4, the density of the light-shielding blocks 211 in the light-transmitting area 200 may gradually decrease in a direction a from the display area 300 toward the center O of the light-transmitting area 200. Wherein the density of the light-shielding blocks 211 in the light-transmitting region 200 near the display region 300 may be the same as the density of the light-shielding blocks 211 in the second sub-display region 302, and the density of the light-shielding blocks 211 located at the center O of the light-transmitting region 201 is the smallest. Alternatively, in the direction a from the display area 300 toward the center O of the light-transmitting area 201, the densities of the light-shielding blocks 211 in the first sub-display area 301 and the light-transmitting area 200 are gradually decreased, that is, the density of the light-shielding blocks 211 located in the first sub-display area 301 near the second sub-display area 302 is the largest, and the density of the light-shielding blocks 211 located at the center O of the light-transmitting area 200 is the smallest.

The density of the light shielding blocks 211 may be implemented in various ways. For example, when the width of the light-shielding block 211 (i.e., the length of the light-shielding block 211 in the direction B) is not changed, the pitch between the adjacent light-shielding blocks 211 (i.e., the length of the color resistor 24 in the direction B) becomes smaller, and the density of the light-shielding blocks 211 becomes larger; the pitch between the adjacent light shielding blocks 211 becomes larger, and the density of the light shielding blocks 211 becomes smaller. Or, when the pitch between the adjacent light shielding blocks 211 is not changed, the width of the light shielding block 211 is increased, and the density of the light shielding block 211 is increased; the width of the light-shielding block 211 becomes small and the density of the light-shielding block 211 becomes small. Or, when the pitch of the adjacent light shielding blocks 211 and the width of the light shielding block 211 are changed simultaneously, the pitch of the adjacent light shielding blocks 211 becomes smaller, the width of the light shielding block 211 becomes larger, and the density of the light shielding blocks 211 becomes larger; the pitch between the adjacent light shielding blocks 211 becomes larger, the width of the light shielding blocks 211 becomes smaller, and the density of the light shielding blocks 211 becomes smaller.

As shown in fig. 4, the width of the light-shielding blocks 211 in the first sub-display area 301 is the largest, and the width of the light-shielding blocks 211 in the light-transmitting area 200 is gradually reduced in a direction from the display area 300 toward the center O of the light-transmitting area 201, so that the density of the light-shielding blocks 211 in the light-transmitting area 200 is gradually reduced. Specifically, the width W2 of the light-shielding block 211 located in the first sub-display region 301 is greater than the width W4 of the light-shielding block 211 located at the center O of the light-transmitting region 200, while the width W3 of the light-shielding block 211 located therebetween (e.g., at the edge of the light-transmitting region 201) is smaller than W2 and greater than W4, i.e., W2 > W3 > W4. The width W1 of the shading block 211 in the second sub-display area 302 is greater than or equal to W4 and smaller than W2, i.e. W2 > W1 ≧ W4.

In order to ensure that the display effect of the panel main body 2 is not affected, the width of the first sub-display area 301 (i.e. the length of the first sub-display area 301 in the direction a) needs to be as small as possible, and the minimum width of the first sub-display area 301 is related to the thickness of the substrate 21, the distance between the backlight module 1 and the substrate 21, and the light-emitting angle range of the light source assembly 12. It should be noted that, because other film layers are further disposed between the backlight module 1 and the substrate 21, a gap is formed between the backlight module 1 and the substrate 21.

Specifically, the minimum width of the first sub-display area 301 is proportional to the thickness of the substrate 21, the distance between the backlight module 1 and the panel main body 2, and the light-emitting angle range of the light source assembly 12, that is, the larger the thickness of the substrate 21 is, the larger the minimum width of the first sub-display area 301 is; the larger the distance between the backlight module 1 and the substrate 21 is, the larger the minimum width of the first sub-display area 301 is; the larger the light-exiting angle range of the light source assembly 12, the larger the minimum width of the first sub-display region 301. The light-emitting angle range of the light source assembly 12 mainly refers to the light-emitting angle range of the first light source 121 in the light source assembly 12, that is, the larger the light-emitting angle range of the first light source 121 is, the larger the minimum width of the first sub-display area 301 is.

In order to further increase the light transmittance of the light-transmitting area 200 and improve the shooting effect of the camera module at the bottom of the display panel, a white color resistor W may be added in the light-transmitting area 200, i.e., the color resistors in the light-transmitting area 201 include a red color resistor R, a green color resistor G, a blue color resistor B and a white color resistor W, as shown in fig. 4. And the color resists in the first and second sub-display sections 301 and 302 may include only the red color resist R, the green color resist G, and the blue color resist B. It should be noted that the white color resists W of the light-transmitting regions 200 close to the display region 300 can be at least partially covered by the light-shielding blocks 211 to reduce the pixel aperture ratio, and at the same time, ensure the density of the light-shielding blocks 211 of the light-transmitting regions 201 close to the display region 300.

In another embodiment, as shown in fig. 5, the array substrate 2b is located on the backlight unit 11, and the color filter substrate 2a is located on the array substrate 2b, that is, the array substrate 2b is located between the backlight unit 11 and the color filter substrate 2 a. The substrate 21, the light-shielding layer 22 and the metal trace 23 are all located in the color film substrate 2a, that is, the array substrate 2b includes the substrate 21, the light-shielding layer 22 and the metal trace 23, the substrate 21 is close to one side of the backlight unit 11, the light-shielding layer 22 is located on one side of the substrate 21 departing from the backlight unit 11, and the metal trace 23 is located on one side of the light-shielding layer 22 departing from the substrate 21. The color filter substrate 2a may include a plurality of color resistors (not shown) and a plurality of light shielding blocks (not shown), and each color resistor is located between two corresponding light shielding blocks.

The light shielding layer 22 covers a side of the metal trace 23 close to the substrate 21. In order to ensure that the display effect of the display panel is not affected, the coverage area of the light shielding layer 22 needs to be as small as possible. The orthographic projection of the light shielding layer 22 on the substrate 21 is completely overlapped with the orthographic projection of the metal wiring 23 on the substrate 21, so that the display effect of the display panel 2 is not affected by the light shielding layer 22, meanwhile, the light beam is prevented from being reflected to the bottom of the display panel through the metal wiring 23, and the shooting effect of the camera shooting component at the bottom of the display panel is improved.

The material of the light shielding layer 22 is black metal. For example, if the metal trace 23 is Mo, the light-shielding layer 22 can be Mo oxide MoO_x. By using molybdenum oxide MoO_xThe low reflection performance of (2) can effectively prevent the light beam from irradiating the metal wiring 23 and then reflecting the light beam to the bottom of the display panel.

As shown in fig. 3, the backlight module 1 may further include a light reflecting layer 15, and the light reflecting layer 15 is located on the periphery of the light transmitting portion 13, that is, the light reflecting layer 15 covers the side wall of the light transmitting portion 13. The light reflecting layer 15 may be a metal film with high reflective performance, for example, the material of the light reflecting layer 15 may be aluminum.

Since the first light source 121 in the light source assembly 12 is located on the peripheral side of the backlight unit 11, and the light-transmitting portion 13 penetrates through the backlight unit 11, that is, the first light source 121 is located on the peripheral side of the light-transmitting portion 13, so that the light beam emitted by the first light source 121 can enter the bottom of the display panel through the side surface of the light-transmitting portion 13, which affects the shooting effect of the bottom of the display panel. Therefore, in the present embodiment, the light reflecting layer 15 covers the side wall of the light transmitting portion 13, so that the light beams irradiated from the first light source 121 to the side surface of the light transmitting portion 13 can be reflected back, thereby effectively preventing the light beams emitted from the first light source 121 from entering the bottom of the display panel through the side surface of the light transmitting portion 13, and improving the shooting effect of the bottom of the display panel.

In addition, since the light reflecting layer 15 is coated on the side wall of the light transmitting portion 13, the thickness of the light reflecting layer 15 can be thin, and a high reflection effect can be achieved. Therefore, the backlight unit 11 does not need to be provided with a light barrier film (the backlight unit in the prior art includes a light barrier film located on the periphery of the backlight hole, the light barrier film has a relatively thick thickness and does not guide light to the panel body, which may affect the display of the panel body region corresponding to the light barrier film), so as to prevent the light barrier film from affecting the display of the panel body region corresponding to the light barrier film, and the light reflection layer 15 is thin, and the panel body region affected by the light reflection layer 15 can be ignored, thereby improving the display effect of the panel body 2.

Further, as shown in fig. 2 and 5, the panel body 2 may further include a lower polarizer 25 and an upper polarizer 26, the lower polarizer 25 is located between the backlight unit 11 and the substrate 21, and the upper polarizer 26 is located on a side of the metal trace 23 facing away from the substrate 21. When the color filter substrate 2a of the panel body 2 is close to the backlight unit 11, that is, when the color filter substrate 2a is located between the backlight unit 11 and the array substrate 2b, the lower polarizer 25 is located between the backlight unit 11 and the color filter substrate 2a, and the upper polarizer 26 is located on a side of the array substrate 2b away from the color filter substrate 2 a. When the array substrate 2b of the panel body 2 is close to the backlight unit 11, that is, when the array substrate 2b is located between the backlight unit 11 and the color filter substrate 2a, the lower polarizer 25 is located between the backlight unit 11 and the array substrate 2b, and the upper polarizer 26 is located on a side of the color filter substrate 2a away from the array substrate 2 b.

Through holes (not shown) can be respectively arranged in the lower polarizer 25 and the upper polarizer 26, and the through holes correspond to the backlight holes 13, so that the light transmittance of the panel body 2 can be further improved by the arrangement of the through holes, and the shooting effect at the bottom of the display panel can be further improved.

The light source assembly is provided with a light shielding layer between the substrate and the metal wiring of the panel main body, so that when the light source assembly provides a light source to the panel main body through the backlight unit, light beams entering the panel main body are prevented from being reflected to the bottom of the display panel through the metal wiring, and the shooting effect at the bottom of the display panel is improved.

Correspondingly, the embodiment of the invention also provides a display device.

As shown in fig. 6, the display device according to the embodiment of the present invention includes a camera module 3 and a display panel 100, where the display panel 100 is the display panel in the above embodiment and is not described in detail herein.

The image pickup assembly 3 is located on a side of the backlight unit 11 away from the panel body 2, and corresponds to the light-transmitting portion 13, that is, an orthographic projection of the image pickup assembly 3 on the backlight unit 11 is located in the light-transmitting portion 13. When the camera in the camera module 3 is turned on, the second light source 122 may be turned off to ensure that the photoreceptor of the camera module 3 can receive external light, thereby ensuring normal shooting of the camera module; when the camera in the camera module 3 is not turned on, the second light source 122 may be turned on to ensure normal display of the display panel.

The display device in this embodiment may be any product or component having a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, and a navigator.

To sum up, this application embodiment sets up the light shield layer through lining between the line at the substrate of panel main part and metal to when the light source subassembly provides the light source to the panel main part through the unit in a poor light, avoid entering into the light beam of panel main part and walk the bottom that the line reflects to display panel through the metal, improve the shooting effect of the subassembly of making a video recording of display panel bottom.
