[0002] This invention relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0003] Under-display camera solutions effectively increase the screen-to-body ratio of displays, which is conducive to realizing full-screen designs and thus provides users with a better visual experience.

[0004] In current under-display camera solutions, a portion of the display area is reused as a camera pre-installation area. The camera is positioned within this pre-installed area, on the side of the display furthest from its light-emitting surface. Specifically, the camera receives light passing through the display within its pre-installed area to capture images. Sufficient light directly affects the camera's image quality. Therefore, improving the light transmittance of the pre-installed area to enhance image quality is a pressing issue that needs to be addressed in under-display camera solutions.

[0038] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes in detail the specific implementation, structure, features and effects of a display panel and display device proposed according to the present invention.

[0039] This invention provides a display panel, including a display area, wherein a plurality of sub-pixels are disposed in the display area, the plurality of sub-pixels are arranged in a plurality of sub-pixel rows, and the extension direction of the sub-pixel rows is a first direction;

[0040] The display area includes a first display area and a second display area, wherein the density of the sub-pixels in the first display area is less than the density of the sub-pixels in the second display area; the first display area includes a plurality of island-shaped first sub-display areas and a first sub-non-display area surrounding the first sub-display areas, wherein the plurality of sub-pixels in the first display area are located in the first sub-display areas;

[0041] The display panel further includes multiple signal lines extending along the first direction; the multiple signal lines include multiple first signal lines; within the first sub-display area, every n adjacent rows of sub-pixels are electrically connected to the same first signal line, where n is a positive integer greater than 1;

[0042] Multiple first connecting wires for electrically connecting the sub-pixel to the corresponding first signal line are located in the first sub-display area.

[0043] The display panel provided in this embodiment of the invention includes a display area, which includes a first display area and a second display area. The density of sub-pixels in the first display area is less than the density of sub-pixels in the second display area. The first display area includes a plurality of first sub-display areas and a first sub-non-display area arranged around the first sub-display area. In the first sub-display area, every n adjacent rows of sub-pixels are electrically connected to the same first signal line. Multiple first connecting wires for electrically connecting sub-pixels and corresponding first signal lines are located in the first sub-display area, so that every n adjacent rows of sub-pixels correspond to one first signal line in the first sub-non-display area, instead of n first signal lines in the prior art. This effectively reduces the total number of first signal lines in the first sub-non-display area, thereby increasing the light transmittance of the first display area.

[0044] The above is the core idea of ​​this application. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0046] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention, for ease of explanation, the schematic diagrams illustrating the structure of the device are not locally enlarged to scale, and the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. Furthermore, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and height should be included.

[0047] Figure 1 This is a schematic diagram of the structure of a display panel in the prior art. For example... Figure 1 As shown, the display panel includes a display area 1 and a non-display area 2 surrounding the display area. The display area 1 includes a first display area 11 and a second display area 12. The density of sub-pixels 30 in the first display area 11 is less than the density of sub-pixels 30 in the second display area 12. The display panel also includes multiple signal lines 20, which include multiple first signal lines 21, multiple second signal lines 22, and multiple third signal lines 23. Each row of sub-pixels 30 is electrically connected to one first signal line 21, one second signal line 22, and one third signal line 23. Every n adjacent first signal lines 21 are electrically connected in the non-display area 2, every n adjacent second signal lines 22 are electrically connected in the non-display area 2, and every n adjacent third signal lines 23 are electrically connected in the non-display area 2. The first signal lines 21, second signal lines 22, and third signal lines 23 passing through the first display area 11 cause a decrease in the light transmittance of the first display area 11.

[0048] Figure 2 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of another display panel provided in an embodiment of the present invention. For example... Figure 2 and Figure 3 As shown, the display panel includes a display area 100, and a plurality of sub-pixels 300 are provided in the display area 100. The plurality of sub-pixels 300 are arranged in a plurality of sub-pixel rows 310, and the extension direction of the sub-pixel rows 310 is a first direction X.

[0049] Display area 100 includes a first display area 110 and a second display area 120. The density of sub-pixels 300 in the first display area 110 is less than the density of sub-pixels 300 in the second display area 120. The first display area 110 includes a plurality of island-shaped first sub-display areas 111 and a first sub-non-display area 112 arranged around the first sub-display areas 111. The plurality of sub-pixels 300 in the first display area 110 are located in the first sub-display areas 111.

[0050] The display panel also includes multiple signal lines 200 extending along a first direction X. The multiple signal lines 200 include multiple first signal lines 210. Within the first sub-display area 111, every n adjacent rows of sub-pixels 300 are electrically connected to the same first signal line 210, where n is a positive integer greater than 1. For example... Figure 2 In the first sub-display area 111, n equals 2 and multiple first connecting wires 410 used to electrically connect the sub-pixel 300 to the corresponding first signal line 210 are located.

[0051] It should be noted that in a full-screen design, optical elements can be placed in the first display area 110, where the sub-pixel density is lower, so that the optical elements can receive more light and thus achieve better device performance.

[0052] It should also be noted that, in order to simplify the structure of the attached diagrams, Figure 2 and Figure 3 Only the first connecting wire 410 between the sub-pixel 300 and the corresponding first signal line 210 in the first display area 110 is shown; the connecting wire between the sub-pixel 300 and the corresponding first signal line 210 in the second display area 120 is not shown. Specifically, in Figure 2 and Figure 3 In the indicated orientation, the sub-pixel 300 within the second display area 120 is electrically connected to the first signal line 210 below it.

[0053] For example, the first connecting wire 410 within the first display area 110 may include at least two different configuration methods, respectively as follows: Figure 2 and Figure 3 As shown. In Figure 2 In the first sub-display area 111, the sub-pixels 300 arranged in the same row are electrically connected to the corresponding first signal lines 210 through a common conductor; Figure 3 In this embodiment, each sub-pixel 300 within the first sub-display area 111 is electrically connected to its corresponding first signal line 210 via an independent wire. The aforementioned arrangement of the first connecting wire 410 is merely an example and not a limitation. In other embodiments of this example, the first connecting wire 410 may employ other arrangements capable of electrically connecting the sub-pixel 300 to its corresponding first signal line 210. For example, such as... Figure 4 As shown, in Figure 2Based on the setup shown, the common wire that is electrically connected to the row sub-pixels 300 in the first sub-display area 111 can also be electrically connected to the corresponding first signal line 210 at both ends to reduce the impact of voltage drop on the brightness uniformity of the row sub-pixels 300.

[0054] Within the first display area 110, sub-pixels 300 are concentrated in the first sub-display area 111. The first non-sub-display area 112 does not include sub-pixels 300, but only has connecting lines between adjacent sub-pixels 300. Therefore, the first non-display area 112 is the main light-transmitting area of ​​the first display area 110. The fewer light-blocking structures in the first non-display area 112, the higher the light transmittance of the first display area 110. In this embodiment, n rows of sub-pixels 300 within the first sub-display area 111 are electrically connected to a first signal line 210, and a first connecting wire 410 is disposed within the first sub-display area 111. This ensures that each row of sub-pixels 300 within the first sub-display area 111 corresponds to only one first signal line 210 in the first sub-non-display area 112. Compared to the prior art where each row of sub-pixels 300 within the first sub-display area 111 corresponds to one first signal line 210 in the first sub-non-display area 112, the number of first signal lines 210 in the first sub-non-display area 112 is significantly reduced, the light-blocking structure in the first sub-non-display area 112 is reduced, and the light transmittance of the first display area 110 is increased. It is understood that the first connecting wire 410 is a necessary configuration for electrically connecting each n rows of sub-pixels 300 to the same first signal line 210. Distributing the light-blocking first connecting wire 410 within the first sub-display area 111 avoids its impact on the light transmittance of the first sub-non-display area 112.

[0055] This embodiment does not limit the specific arrangement of the sub-pixels 300 within the display area 100. For example, such as... Figures 2 to 4 As shown, odd-numbered subpixel rows and even-numbered subpixel rows can be staggered; as... Figures 5 to 7 As shown, the sub-pixels 300 within the display area 100 can also be arranged in a matrix.

[0056] Figures 1 to 7 The structure of the display panel shown is for illustrative purposes only and is not a limitation on the number of first sub-display areas 111, the positional relationship between each first sub-non-display area 111, the number of sub-pixels 300 within the first sub-non-display area 111, or their setting method.

[0057] Figure 8 This is a schematic diagram of the structure of another display panel provided in an embodiment of the present invention. Figure 2 Based on the display panel shown, Figure 8The display panel shown includes multiple signal lines 200 and multiple second signal lines 220. Multiple sub-pixels 300 electrically connected to the same first signal line 210 are electrically connected to the same second signal line 220. Multiple second connecting wires 420 for electrically connecting the sub-pixels 300 and the corresponding second signal lines 220 are located in the first sub-display area 111.

[0058] also, Figures 3 to 7 The multiple signal lines 200 in the display panel shown may also include multiple second signal lines 220; for specific structures, please refer to [reference needed]. Figures 9 to 13 .

[0059] It should be noted that the above configuration allows the n rows of sub-pixels 300 in the first sub-display area 111 to be electrically connected to a second signal line 220 in addition to being electrically connected to a first signal line 210. Furthermore, the second connecting wire 420 is disposed in the first sub-display area 111. Consequently, the n rows of sub-pixels 300 in the first sub-display area 111 correspond to only one second signal line 220 in the first sub-non-display area 112. Compared to the prior art where each row of sub-pixels 300 in the first sub-display area 111 corresponds to one second signal line 220 in the first sub-non-display area 112, the number of second signal lines 220 in the first sub-non-display area 112 is significantly reduced in the technical solution provided in this embodiment. The light-blocking structure in the first sub-non-display area 112 is further reduced, and the light transmittance of the first display area 110 is further increased. It is understandable that the second connecting wire 420 is a necessary setting to realize that every n rows of sub-pixels 300 are electrically connected to the same second signal line 220. Setting the light-shielding second connecting wire 420 in the first sub-display area 111 can prevent it from affecting the light transmittance of the first sub-non-display area 112.

[0060] Furthermore, in Figures 8 to 13 Based on the display panel structure shown, the multiple signal lines 200 also include multiple third signal lines 230. Multiple sub-pixels 300 electrically connected to the same first signal line 210 are electrically connected to the same third signal line 230. Multiple third connecting wires 430 for electrically connecting the sub-pixels 300 and the corresponding third signal lines 230 are located in the first sub-display area 111. For specific structures, please refer to [reference needed]. Figures 14 to 19 .

[0061] It should be noted that the above configuration allows the n rows of sub-pixels 300 in the first sub-display area 111 to be electrically connected to a third signal line 230 in addition to being electrically connected to a first signal line 210 and a second signal line 220. The third connecting wire 430 is disposed in the first sub-display area 111. As a result, the n rows of sub-pixels 300 in the first sub-display area 111 correspond to only one third signal line 230 in the first sub-non-display area 112. Compared with the prior art, where each row of sub-pixels 300 in the first sub-display area 111 corresponds to one third signal line 230 in the first sub-non-display area 112, the number of third signal lines 230 in the first sub-non-display area 112 is significantly reduced in the technical solution provided in this embodiment, the light-blocking structure in the first sub-non-display area 112 is further reduced, and the light transmittance of the first display area 110 is further increased. It is understandable that the third connecting wire 430 is a necessary setting to realize that every n rows of sub-pixels 300 are electrically connected to the same third signal line 230. Setting the light-shielding third connecting wire 430 in the first sub-display area 111 can prevent it from affecting the light transmittance of the first sub-non-display area 112.

[0062] For example, the first signal line 210, the second signal line 220 and the third signal line 230 are each a scan line, a light-emitting drive signal line and a reset signal line, and they are all different.

[0063] It should be noted that in organic light-emitting display panels, driving circuits such as 7T1C are typically used to drive the corresponding sub-pixels 300 to emit light. Adjacent n rows of sub-pixels 300 can share the same scan signal, light-emitting driving signal, and reset signal. Therefore, in this embodiment, the first signal line 210, the second signal line 220, and the third signal line 230 are set to be any one of the scan line, the light-emitting driving signal line, and the reset signal line, respectively, and each is different. On the basis of ensuring the normal operation of the driving circuit, the sharing of the three different signals can also achieve the beneficial effect of simplifying the driving signal.

[0064] It is understood that, depending on the sub-pixel driving circuit, the number and type of signal lines that can be shared by each adjacent n rows of sub-pixels 300 are different. This embodiment only uses the example of each adjacent n rows of sub-pixels 300 sharing the first signal line 210, the second signal line 220, and the third signal line 230, where the first signal line 210, the second signal line 220, and the third signal line 230 are any one of the scan line, the light emission driving signal line, and the reset signal line, and each is different, to illustrate rather than limit. Designers can reasonably set the number and type of signal lines that can be shared by each adjacent n rows of sub-pixels 300 according to actual needs.

[0065] like Figure 18As shown, within the first sub-display area 111, each sub-pixel 300 is connected to the corresponding first signal line 210, second signal line 220, and third signal line 230 via a first connecting wire 410, a second connecting wire 420, and a third connecting wire 430, respectively.

[0066] It should be noted that the above-mentioned configuration method has low manufacturing difficulty, and the lengths of the first connecting wire 410, the second connecting wire 420 and the third connecting wire 430 are small, occupying a small area of ​​the first sub-display area 111, which is conducive to increasing the area of ​​the first sub-non-display area 112, and thus conducive to increasing the light transmittance of the first display area 110.

[0067] See also Figure 17 and Figure 19 Multiple first connecting wires 410 include multiple first common wires 411 and multiple first single wires 412; multiple second connecting wires 420 include multiple second common wires 421 and multiple second single wires 422; and multiple third connecting wires 430 include multiple third common wires 431 and multiple third single wires 432. Any row of sub-pixels 300 in every n adjacent rows of sub-pixels 300 constitutes a first sub-pixel row 311, and the remaining sub-pixels constitute n-1 second sub-pixel rows 312. In each first sub-pixel row 311, each sub-pixel 300 is connected to the corresponding first signal line 210, second signal line 220, and third signal line 230 via a first single wire 412, a second single wire 422, and a third single wire 432, respectively. Each second sub-pixel row 312 corresponds to a first common wire 411, a second common wire 421, and a third common wire 431. The first common wire 411, the second common wire 421, and the third common wire 431 are respectively connected to the corresponding first signal line 210, the second signal line 220, and the third signal line 230. In the second sub-pixel row 312, the sub-pixel 300 is connected to the corresponding first common wire 411, the second common wire 421, and the third common wire 431 through a first single wire 412, a second single wire 422, and a third single wire 432.

[0068] It should be noted that this configuration allows the first single wire 412, second single wire 422, and third single wire 432 corresponding to each sub-pixel 300 in the first display area 110 to be configured in the same way. This enables them to be formed using the same processes and parameters, eliminating the need for special design for specific sub-pixels 300, thus reducing the design and manufacturing complexity of the display panel. Furthermore, the first common wire 411, second common wire 421, and third common wire 431 facilitate routing between adjacent sub-pixels 300 without reducing the pixel aperture ratio of the display panel.

[0069] In this embodiment, the display panel may further include multiple driving circuits, each driving circuit being electrically connected to a sub-pixel. Each driving circuit includes a thin-film transistor and a storage capacitor. Specifically, Figure 20 This is a cross-sectional structural diagram of a display panel provided in an embodiment of the present invention. Figure 20 As shown, in the driving circuit, the gate 510 of the thin-film transistor 500 is located in the first metal layer, and the electrode 600 of the storage capacitor, which is farthest from the corresponding sub-pixel 300, is located in the second metal layer. Any two adjacent signal lines among the multiple first signal lines 210, multiple second signal lines 220, and multiple third signal lines 230 are respectively disposed in the first metal layer and the second metal layer.

[0070] It should be noted that the first signal line 210, the second signal line 220, and the third signal line 230 corresponding to each sub-pixel row 310 are disposed within the gap between the sub-pixel row 310 and its adjacent sub-pixel rows 310. It is worth noting that any two adjacent signal lines include two signal lines located on opposite sides of the same sub-pixel row 310. For example, in... Figure 20 In the above, the third signal line 230 located between the first sub-pixel 301 and the second sub-pixel 302 and the first signal line 210 located between the second sub-pixel 302 and the third sub-pixel 303 are two adjacent signal lines.

[0071] It should also be noted that setting any two adjacent signal lines on the first metal layer and the second metal layer respectively helps to reduce the distance between the two adjacent signal lines, avoids the signal interference problem that occurs when adjacent signal lines are set on the same layer, and can reduce the width of the space occupied by multiple signal lines in the signal line arrangement direction, thereby reducing the impact of the signal lines on the area of ​​the first sub-non-display area 112, which is conducive to improving the light transmittance of the first display area 110.

[0072] Figure 21 This is a schematic diagram of another display panel provided in an embodiment of the present invention. For example... Figure 21 As shown, in Figures 1 to 20 Based on the signal line setting method, the display panel also includes multiple power lines 700. The power lines 700 extend along the second direction Y, which is perpendicular to the first direction X. All sub-pixels 300 in the multiple first sub-display areas 111 arranged along the second direction Y are electrically connected to the same power line 700. The electrical connection line 710 between the sub-pixel 300 and the power line 700 is located in the first sub-display area 111.

[0073] It should be noted that in the prior art, multiple sub-pixels 300 arranged along the second direction Y in the first sub-display area 111 are electrically connected to a power line 700. However, in the technical solution provided in this embodiment, multiple columns of sub-pixels 300 in the first sub-display area 111 are all electrically connected to a power line 700, which effectively reduces the number of power lines 700 in the first sub-non-display area 112 and reduces the number of light-blocking structures in the first sub-non-display area 112, which is beneficial to improving the light transmittance in the first display area 110.

[0074] Figure 22 This is a schematic diagram of the structure of another display panel provided in an embodiment of the present invention. Figure 21 Based on the display panel shown, as Figure 22 As shown, the display panel also includes multiple data lines 800, which extend along a second direction Y. Multiple sub-pixels 300 arranged along the second direction Y are electrically connected to a single data line 800. Among the multiple data lines 800 passing through the same first sub-display area 111, the gap between any two adjacent data lines 800 is a first gap. The minimum distance of the first gap in the first sub-non-display area 112 is D1, and the minimum distance of the first gap in the first sub-display area 111 is D2, where D1 is less than D2.

[0075] It should be noted that the above configuration allows multiple data lines 800 passing through the same first sub-display area 111 to be more concentratedly distributed in the first sub-non-display area 112, and the concentrated distribution area is located in the line distribution area between adjacent sub-pixels 300 in the first sub-non-display area 112, thereby effectively reducing the impact of the data lines 800 on the light transmittance of the first display area 110.

[0076] Figure 23 It is along Figure 22 A cross-sectional structural diagram of the dashed line AB. The display panel may also include multiple driving circuits, each electrically connected to a sub-pixel. The driving circuits include thin-film transistors and storage capacitors. (Example...) Figure 23 As shown, in the driving circuit, the source 520 and drain 530 of the thin film transistor 500 are located in the third metal layer, and the power line 700 and the portions of multiple data lines 800 located in the first sub-display area 111 are located in the third metal layer. Along the first direction X, the portions of each data line 800 located in the first sub-non-display area 112 are alternately arranged in the first metal layer and the second metal layer.

[0077] It should be noted that the above arrangement allows the power lines 700 and data lines 800 in the first sub-display area 111 to be arranged in the same layer, facilitating the use of the same material in the same process and simplifying the manufacturing process. Simultaneously, it ensures that the power lines 700 and data lines 800 can be arranged in different layers from the signal lines 200 extending along the first direction X, avoiding signal interference caused by intersections with the signal lines. Furthermore, the alternating arrangement of the data lines 800 in the first sub-non-display area 112 along the first direction X on the first metal layer and the second metal layer reduces the distance between adjacent data lines 800 while ensuring that the intersections between the data lines 800 and the power lines 700 do not electrically connect. This also reduces signal interference between adjacent data lines 800 in the first sub-non-display area 112 and the width of the space occupied by multiple data lines 800 in the data line arrangement direction, thereby reducing the impact of the data lines 800 on the area of ​​the first sub-non-display area 112 and improving the light transmittance of the first display area 110.

[0078] Figure 24 This is a schematic diagram of another display panel provided in an embodiment of the present invention. For example... Figure 24 As shown, the display panel also includes a main non-display area 101, which surrounds the display area 100. Along the first direction X, a first gate driving circuit 910 and a second gate driving circuit 920 are respectively disposed within the main non-display areas 101 located on opposite sides of the display area 100. A first signal line 210, a second signal line 220, and a third signal line 230 electrically connected only to the sub-pixels 300 within the first display area 110 are designated as target signal lines. Each target signal line includes a first sub-section 201 and a second sub-section 202 located on opposite sides of the first display area 110 within the second display area 120. The first sub-section 201 is disposed near the first gate driving circuit 910, and the second sub-section 202 is disposed near the second gate driving circuit 920. The first sub-section 201 is electrically connected to the first gate driving circuit 910, and the second sub-section 202 is electrically connected to the second gate driving circuit 920.

[0079] It should be noted that the technical solution provided in this embodiment ensures that the target signal line can drive the corresponding sub-pixel 300 normally, while preventing the target signal line from passing through the first display area 110, thereby avoiding the target signal line from reducing the light transmittance of the first display area 110.

[0080] See also Figure 24Multiple sub-pixels 300 in the second display area 120 are arranged in a first matrix, multiple sub-pixels 300 in the first sub-display area 111 are arranged in a second matrix, and multiple first sub-display areas 111 are arranged in a third matrix. The row and column directions of the first, second, and third matrices are the same, so that the pixel array in the display panel is more organized and easier to design and apply.

[0081] Furthermore, the sub-pixels 300 within the first sub-display area 111 are arranged in p rows and q columns, where p and q are both positive integers, and q is a multiple of 3. For example, as shown... Figure 24 As shown, p equals 2 and q equals 3. It can be understood that in other embodiments of this example, p and q can be other values, provided that p and q are both positive integers and q is an integer multiple of 3.

[0082] It should be noted that a conventional display panel includes sub-pixels of three colors: red, green, and blue. A pixel unit is composed of red, blue, and green sub-pixels. In a pixel unit, the red, green, and blue light emitted by the three different colored sub-pixels are mixed to obtain the target white light. In this embodiment, the distance between adjacent first sub-display areas 111 is relatively large. It is difficult for the light emitted by a sub-pixel 300 in any one first sub-display area 111 to mix with the light emitted by the sub-pixels 300 in adjacent first sub-display areas 111 to obtain the target white light. Therefore, to avoid color cast, the number of columns of sub-pixels 300 in the first sub-display area 111 is set to a multiple of 3, so that each first sub-display area 111 includes an integer number of pixel units.

[0083] In addition, the total number of sub-pixel rows 310 in the display panel can be an integer multiple of p, so that the connection method of each adjacent n rows of sub-pixels 300 is exactly the same, which is convenient for design.

[0084] Figure 25 This is a schematic diagram of the structure of a display device provided in an embodiment of the present invention. Figure 25 As shown, the display device 40 includes the display panel 41 described in any embodiment of the present invention. Since the display device 40 provided in this embodiment includes the display panel 41 as described in any embodiment of the present invention, it has the same or corresponding beneficial effects as the display panel 41 it includes, and will not be described again here.

[0085] See also Figure 25 The display device 40 also includes an optical electronic element 50, which is disposed on the side of the display panel 41 in the first display area 110 away from its light-emitting surface.

[0086] It should be noted that since the reserved area for optical electronic components (first display area 110) can also be used for display, the display surface of the display device 40 facing the user side can be used for full-screen display, thus obtaining a full-screen display device.

[0087] For example, the optical electronic component 41 may include one or more of a camera module, a light sensor, and an ultrasonic distance sensor.

[0088] For example, if the display device 40 is a mobile phone or tablet, and the optical electronic component 41 is a camera module, the first display area 110 corresponds to the area where the front-facing camera of the mobile phone or tablet is located. The first sub-display area is used for display, and the first sub-non-display area is used to allow incident light to enter the front-facing camera for the front-facing camera to capture external images. When the optical electronic component 41 is a light sensor, the light sensor can be used to sense external light and adjust the brightness of the display device 40, or it can be used to sense whether there is a fingerprint outside, thereby performing fingerprint recognition. The light sensor also receives external light through the first sub-non-display area of ​​the first display area 110 and then performs sensing. The first sub-display area is used to display images together with the second display area.

[0089] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
