Mode for Carrying Out the Invention

[0022] Hereinafter, referring to the drawings, the technical solutions in the embodiments of the present disclosure will be clearly and completely described. Of course, it should be understood that the embodiments described here are only a part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art shall be included within the scope of the present disclosure.

[0023] The display device according to the embodiment of the present disclosure is applicable to any terminal having a display function such as a mobile phone, a flat panel display, a computer, a television monitor, etc. The display device can be any device capable of displaying images such as videos (for example, videos), still images (for example, still images), characters, pictures, etc.

[0024] Hereinafter, the so-called "display surface side" means the side where the display device or the display panel performs image display, and the "non-display panel side" means the opposite side of the display surface side of the display device or the display panel.

[0025] In some embodiments, the display device includes a sensing element, and taking the case where the terminal to which the display device is applied is a mobile phone as an example, the display device includes a sensing element such as a front camera, a light sensor, and a 3D sensing module, and these sensing elements need to sense light rays from the display surface side of the display device in order to realize their corresponding functions. For example, when taking an image, the front camera of a mobile phone needs to collect light from a subject located in front of the mobile phone (i.e., on the display surface side), thereby enabling image capture.

[0026] In one related technology, as shown in Figures 1A and 1B, the display panel 11 of the display device 100 has a display area A1 and a non-display area B1, and a hole is made in the display panel 11 and a sensing member 2 (e.g., a front camera) is embedded in the hole, so that the sensing member 2 can sense light rays from the display surface side of the display panel 11.

[0027] In other related technologies, as shown in Figures 2A and 2B, the display panel 12 of the display device 200 has a display area A2 and a transparent area B2, the sensing member 2 is positioned on the non-display side of the display panel 12 of the display device 200, and the sensing member 2 faces the transparent area B2 of the display panel 12, that is, the orthographic projection of the sensing member 2 on the display surface of the display panel 12 is within the transparent area B2. Thus, light rays from the display surface side of the display panel 12 pass through the transparent area B2 and are detected by the sensing member 2.

[0028] In the two arrangement methods of the sensing element 2 described above, there are areas on the display surface of the display panel that cannot be displayed, reducing the screen occupancy rate of the display device. As a result, the ratio of the display area of ​​the display panel to the total area of ​​the display panel does not reach 100 percent, and full-screen display cannot be achieved.

[0029] To achieve a higher screen-to-body ratio, in some embodiments of this disclosure, as shown in Figures 3A and 3B, the display device 300 comprises a display panel 13 and a sensitive member 2. The display panel 13 has a sensitive member area C1 and a non-sensitive member area C2, the non-sensitive member area C2 being capable of displaying images, and the non-sensitive member area C2 may, for example, surround a transparent, image-displayable sensitive member area C1, or it may surround half of the sensitive member area C1. The sensitive member 2 is positioned on the non-display side of the display panel 13, and the sensitive member 2 faces the sensitive member area C1 of the display panel 13, that is, the orthographic projection of the sensitive member 2 on the display surface of the display panel 13 is within the sensitive member area C1.

[0030] The sensing surface of the sensing element 2 is directed toward the display panel 13. Since the sensing element region C1 is transparent, the sensing element 2 can sense light rays from the display surface side of the display panel 13 by passing through the sensing element region C1 and perform the corresponding operation. Taking the case where the sensing element 2 is a front camera as an example, the front camera takes in light rays from a subject on the display surface side of the display panel 13 through the sensing element region C1, forms an image, and captures an image of the subject.

[0031] In order to increase the light transmittance of the sensitive member area C1 and allow the sensitive member 2, which is located on the non-sensitive side of the display panel 13, to transmit light rays from the display side of the display panel 1 through the sensitive member area C1, in some embodiments, as shown in Figures 4A and 4B, the display panel 13 is designed such that the display area of ​​the display panel 13 (including the sensitive member area C1 and the non-sensitive member area C2) includes, for example, a plurality of pixel dots 10 arranged in an array.

[0032] To more clearly explain the proposed technology of this disclosure, the following describes the configuration of region E, which is defined from the display surface of the display panel 13, and Figure 4B is an enlarged structural diagram of region E. Region E includes a part of the non-sensitive member region C2 and the sensitive member region C1. The "part of the non-sensitive member region C2" refers to the region of the non-sensitive member region C2 that is adjacent to the sensitive member region C1 and located around the sensitive member region C1. The structure of the region of the non-sensitive member region C2 located outside of region E can be described by referring to the structure of a part of the region located within region E of the non-sensitive member region C2.

[0033] A method is employed to reduce the PPI (Pixels Per Inch, pixel density) of the sensitive element region C1. That is, by reducing the number of pixel dots 10 in the sensitive element region C1 compared to the non-sensitive element region C2, the space occupied by the pixel dots 10 in the sensitive element region C1 is reduced, creating space for light rays to pass through and thereby achieving high light transmittance in the sensitive element region C1.

[0034] However, the inventors of this disclosure have discovered the following through their research.

[0035] As shown in Figure 4B, the display area of ​​the display panel 13 (for example, area E including a part of the non-sensitive member area C2 and the sensitive member area C1) is provided with a plurality of first wires 20 extending in a first direction and a plurality of second wires 30 extending in a second direction, with the plurality of first traces 20 and the plurality of second traces 30 being spaced apart. The first direction and the second direction intersect, and exemplary, the first direction is the column direction in which a plurality of pixel dots 10 are arranged, and the second direction is the row direction in which a plurality of pixel dots 10 are arranged. When the first direction is the column direction and the second direction is the row direction, the first wires include data lines, initialization signal lines, first power lines (Vdd lines), second power lines (Vss lines), etc., and the second wires include gate lines, control lines, common voltage signal lines (Com lines), etc. Because the PPI of the non-sensitive member region C2 is high, the arrangement of the first wiring 20 is dense, and the spacing between two adjacent first wirings 20 is small.

[0036] The arrangement density of the first wiring 20 in the sensitive element region C1 is the same as that of the non-sensitive element region C2. This is because, for each sub-pixel row where multiple pixel dots 10 in the sensitive element region C1 are located, the PPI of the C22 and C24 regions in the non-sensitive element region C2 matches that of the C21 and C23 regions in the non-sensitive element region C2. Therefore, the arrangement density of the first wiring 20 and second wiring 30 in the C22 and C24 regions in the non-sensitive element region C2 matches that of the first wiring 20 and second wiring 30 in the C21 and C23 regions in the non-sensitive element region C2. As a result, the wiring density of these sub-pixel rows in the sensitive element region C1 does not decrease due to a decrease in their PPI.

[0037] Thus, in the process in which a light ray passes through the sensitive member region C1 and propagates between the display surface side of the display panel 13 and the sensitive member 2, the multiple first wires 20 in the sensitive member region C1 are densely arranged, and the spacing between two adjacent first wires 20 is small. As a result, when a light ray propagates through the gap between two adjacent first wires 20, diffraction occurs, which may affect the accuracy of the light ray information sensed by the sensitive member. Here, the diffraction phenomenon of light refers to the phenomenon in which, when light hits an obstacle or small hole during its propagation, the light deviates from its linear propagation path and propagates behind the obstacle. The smaller the spacing between obstacles and the smaller the small hole, the more pronounced the diffraction phenomenon becomes. When the linearity of the small hole is as small as the wavelength of light, the diffraction phenomenon of light is extremely intense, the diffraction phenomenon that occurs when light propagates becomes prominent, and the light ray becomes dimmer.

[0038] Taking the example that the sensing element 2 is a front camera, when the front camera acquires an image via the sensing element area C1 of the display panel 13, the front camera needs to acquire light rays from a subject located on the display surface side of the display panel 13 via the sensing element area C1. However, because the first wiring 20 is densely arranged, light diffraction occurs when the light rays pass through the sensing element area C1, resulting in inaccurate light ray information collected by the front camera. This reduces the imaging effectiveness of the front camera, leading to problems such as low image brightness and poor resolution.

[0039] In view of the above, as shown in Figures 5A and 5B, some embodiments of the present disclosure provide an array substrate 131 having a non-sensitive member region C2 and a transparent sensitive member region C1. Both the sensitive member region C1 and the non-sensitive member region C2 have a display function, and the non-sensitive member region C2 may, for example, surround the sensitive member region C1 or partially surround the sensitive member region C1.

[0040] The array substrate 131 has a non-sensitive member region C2 and a transparent sensitive member region C1. When the array substrate 131 is applied to a display device including a sensitive member 2, light rays can pass through the transparent sensitive member region C1 and propagate between the display surface side of the array substrate 131 and the sensitive element 2. That is, light rays from the display surface side can pass through the sensitive member region C1 and be detected by the sensitive member 2.

[0041] The array substrate 131 includes a plurality of first wirings 20 extending in a first direction. The plurality of first wirings 20 are spaced apart, and among the plurality of first wirings 20, the wiring that passes through the sensing member region C1 is a selected first wiring 201, and the plurality of selected first wirings 201 are divided into at least one group, and each selected first wiring in each group includes at least two adjacent selected first wirings 201, and each selected first wiring 201 of each group converges in the sensing member region C1 to form a first convergence portion 50.

[0042] For example, as shown in Figure 5A, the first wirings numbered L1 to L6 are selected first wirings 201. Multiple selected first wirings 201 may be divided into three groups, and each group of selected first wirings includes two adjacent selected first wirings 201. The two selected first wirings 201 included in each group of selected first wirings converge in the sensing member region C1 to form one first convergence section 50, thereby the three groups of selected first wirings 201 converge in the sensing member region C1 to form three first convergence sections 50.

[0043] For example, as further shown in Figure 5A, the selected first wirings 201 numbered L1 and L2 converge within the sensing member area C1 as the selected first wirings of one grape to form the first convergence section 50, the selected first wirings 201 numbered L3 and L4 converge within the sensing member area C1 as the selected first wirings of one grape to form the first convergence section 50, and the selected first wirings 201 numbered L5 and L6 converge within the sensing member area C1 as the selected first wirings of one grape to form the first convergence section 50. Here, taking two selected first wirings 201 numbered L1 and L2 as an example, the selected first wiring 201 numbered L2 includes a first portion extending in a first direction and a second portion extending in a second direction. The first and second portions are arranged sequentially alternately and are co-connected. This structure causes the selected first wiring 201 numbered L2 to approach the selected first wiring 201 numbered L1 in the sensing member area C1, forming a first convergence section 50. The first convergence section 50 can be understood to include the portion of the selected first wiring 201 numbered L1 located in the sensing member area C1, and the portion of the selected first wiring 201 numbered L2 located in the sensing member area C1. The structures of the other two first convergence sections 50 are similar to those of the first convergence sections 50 described above, so their explanation is omitted here.

[0044] As shown in Figures 6A to 6C, the array substrate 131 further includes at least one light-shielding bar 40. The at least one first light-shielding bar 40 is positioned on the side of the array substrate 131 away from or adjacent to the display surface side of the plurality of selected first wirings 201, and the orthographic projection of each first light-shielding bar 40 on the display surface of the array substrate 131 (i.e., positioned on the display surface when the array substrate 131 is applied to a display panel) covers the orthographic projection of one first convergence section 50 on the display surface.

[0045] The embodiments of this disclosure do not limit the position of the at least one first light-shielding bar 50 relative to the plurality of first arrangements 20, as long as the orthographic projection of each first light-shielding bar 40 on the display surface of the array substrate 131 covers the orthographic projection on the display surface of one first convergence section 50. This allows one first light-shielding bar 40 to shield the gap between at least two adjacent selected first wirings 201 of one first convergence section 50, thereby avoiding diffraction caused by light rays passing through the gap between the selected first wirings 201 of the first convergence section 50.

[0046] Illustratively, Figure 6B shows a case where the at least one first light-shielding bar 40 is positioned on the side of the array substrate 131 of the plurality of selected first wirings 201 that is close to the display surface side, and the at least one first light-shielding bar 40 is positioned on the side of the plurality of selected first wirings 201 that is away from the base substrate 80. Figure 6C shows a case where the at least one first light-shielding bar 40 is positioned on the side of the array substrate 131 of the plurality of selected first wirings 201 that is away from the display surface side, and the at least one first light-shielding bar 40 is positioned on the side of the plurality of selected first wirings 201 that is close to the base substrate 80.

[0047] In some embodiments, as shown in Figure 6B, the at least one first light-shielding bar 40 is positioned on the side of the array substrate 131 adjacent to the display surface side of the plurality of selected first wirings 201, and the at least one first light-shielding bar 40 is positioned on the side of the plurality of selected first wirings 201 away from the base substrate 80. Thus, the manufacturing of the first light-shielding bar 40 can utilize the manufacturing process of the light-shielding pattern for blocking the active layer of the thin-film transistors on the array substrate 131, eliminating the need to provide a separate process for manufacturing the first light-shielding bar 40 and simplifying the manufacturing process of the array substrate 131.

[0048] As shown in Figure 5B, the at least one first light-shielding bar 40 is positioned on the side of the array substrate 131 of the plurality of selected first wirings 201 that is away from or close to the display surface, and the orthographic projection of each first light-shielding bar 50 on the display surface covers the orthographic projection of the first convergence section 50 on the display surface. This means that the number of first light-shielding bars 50 is the same as the number of first convergence sections 50.

[0049] In the array substrate 131 according to the embodiment of the present disclosure, the selected first wirings 201 of the sensitive member region C1 are grouped, and each group of selected first wirings 201 includes at least two adjacent selected first wirings 201, and each selected first wiring 201 of each group converges in the sensitive member region C1 to form a first convergence portion 50. This corresponds to bringing each selected first wiring 201 of each group of selected first wirings closer to each other in the sensitive member region C1, so that two adjacent selected first wirings 201 of each group become closer in the sensitive member region C1, while the distance between two adjacent first convergence portions 50 becomes greater, and the distance between two adjacent first convergence portions 50 is greater than the distance between two adjacent first wirings 20 in the non-sensitive member region C2.

[0050] Furthermore, by providing at least one first light-shielding bar 40, the gaps between at least two adjacent selected first wirings 201 in the first convergence section 50 are blocked, preventing light rays from passing through these gaps and preventing the occurrence of light diffraction phenomena caused by light rays passing through the gaps between at least two selected first wirings 201 in the first convergence section 50.

[0051] Thus, when a light ray passes through the transparent sensitive member region C1 of the array substrate 131, it passes through the space between two adjacent first light-shielding bars 40. The distance between two adjacent first convergence sections 50 is greater than the distance between two adjacent first wirings 20 in the non-sensitive member region C2. That is, in the transparent sensitive member region C1, the arrangement density of the multiple first convergence sections 50 formed after each selected first wiring 201 of each group of selected first wirings converges (corresponding to the arrangement density of the multiple first light-shielding bars 40) is lower than the arrangement density when the multiple first wirings 20 do not converge. Therefore, when a light ray passes through the transparent sensitive member region C1, diffraction is reduced, the influence of light diffraction on ray brightness is reduced, and the accuracy of the ray information sensed by the sensitive member 2 is improved.

[0052] Taking the example that the sensing element 2 is a front camera, the diffraction phenomenon is reduced when light rays pass through the transparent sensing element region C1, thereby improving the imaging effect of the front camera and significantly improving the brightness and resolution of the resulting image.

[0053] In some embodiments, as shown in Figure 5A, in the transparent sensitive member region C1 of the array substrate 131, the spacing a between two adjacent first convergence sections 50 is greater than the spacing b between two adjacent first wirings in the non-sensitive member region C2. In each first convergence section 50, the spacing c between two adjacent selected first wirings 201 is smaller than the spacing b between two adjacent first wirings in the non-sensitive member region C2.

[0054] In the above embodiment, the spacing a between two adjacent first convergence sections 50 is greater than the spacing b between two adjacent first wirings 20 in the non-sensitive member region C2. The spacing a between two adjacent first convergence sections 50 is the distance between the two closest selected first wirings 201 located within the two adjacent first convergence sections 50. Thus, the spacing a between two adjacent first convergence sections 50 is greater than the spacing b between two adjacent first wirings 20 located in the non-sensitive member region C2. Correspondingly, the spacing between two adjacent first light-shielding bars 40 is greater than the spacing b between two adjacent first wirings 20 in the non-sensitive member region C2. As a result, diffraction is reduced when light rays pass through the transparent sensitive member region C1.

[0055] Furthermore, in each first convergence section 50, the distance c between two adjacent selected first wirings 201 is smaller than the distance b between two adjacent first wirings 20 in the non-sensitive member region C2. As a result, in each first convergence section 50, two adjacent selected first wirings 201 are closer to each other, reducing the dimensions of the first convergence section 50 in the direction perpendicular to the extending direction of the first convergence section 50 (i.e., the width of the first convergence section 50), thereby ensuring a larger distance between two adjacent first convergence sections 50. This reduces the diffraction phenomenon of light, and also allows the width of the first light-shielding bar 40, which blocks the gap between at least two adjacent selected first wirings 201 in the first convergence section 50, to be narrowed, allowing more light rays to pass through the sensitive member region C1.

[0056] In some embodiments, the number of selected first wires 201 included in each group's selected first wire is not limited, and each group's selected first wire may include two selected first wires 201, as shown in Figures 5A, 5B, and 6A to 6C. Alternatively, each group's selected first wire may include two or more selected first wires 201, for example, the number of selected first wires 201 included in each group's selected first wire 201 may be three, four, or five.

[0057] In some embodiments, the number of selected first wirings 201 included in the selected first wiring of each group is the same.

[0058] For example, the number of selected first wirings 201 included in the selected first wiring of each group is 2, or the number of selected first wirings 201 included in the selected first wiring of each group is 3, 4, or some other number. Figure 5A shows the case where each selected first wiring of each group includes 2 selected first wirings 201, which allows the widths of the multiple first convergence sections 50 corresponding to the selected first wiring of multiple groups to be all equal or nearly equal, and the widths of the first light-shielding bars 40 to be equal or nearly equal. In this way, the degree of diffraction reduction for light rays becomes equal or nearly equal in each region of the sensitive member region C1, and the light rays transmitted through each region of the sensitive member region C1 become uniform, thereby further improving the accuracy of the light ray information sensed by the sensitive member 2.

[0059] In some embodiments, the distance between two adjacent first convergence sections 50 is equal. In each first convergence section 50, the gap between each adjacent pair of selected first wirings 201 is equal.

[0060] For example, as shown in Figure 5A, the distance between two adjacent first convergence sections 50 is a in both cases. In each first convergence section 50, if each selected first wiring contains three or more selected first wirings 201, the distance between each pair of adjacent selected first wirings 201 is equal.

[0061] With this design, the spacing between two adjacent first convergence sections 50 is equal, and therefore the spacing between two adjacent first light-shielding bars 40 is also equal or nearly equal. In each first convergence section 50, the spacing between each adjacent pair of selected first wirings 201 is equal, so the widths of all the first convergence sections 50 are equal, and the widths of all the first light-shielding bars 40 are equal or nearly equal. Thus, the degree of reduction in light ray diffraction is equal or nearly equal in each region of the sensitive member region C1, and the light rays transmitted through each region of the sensitive member region C1 become more uniform, thereby improving the accuracy of the light ray information sensed by the sensitive member 2.

[0062] In some embodiments of this disclosure, the effect of reducing the diffraction phenomenon of light can be further enhanced by setting the width of the first light-shielding bar 40 and the distance between two adjacent first light-shielding bars 40 to an appropriate range.

[0063] Note that the width d of the first light-shielding bar 40 refers to the dimension of one first light-shielding bar 40 in a direction perpendicular to the extending direction of the first light-shielding bar 40, as shown in Figure 6A. The spacing e between two adjacent first light-shielding bars 40 refers to the spacing between two adjacent first light-shielding bars 40 in a direction perpendicular to the extending direction of the first light-shielding bar 40. For example, if the extending direction of the first light-shielding bar 40 is the first direction, the width d of the first light-shielding bar 40 refers to the dimension of one first light-shielding bar 40 in a direction perpendicular to the first direction. The spacing e between two adjacent first light-shielding bars 40 refers to the spacing between two adjacent first light-shielding bars 40 in a direction perpendicular to the first direction.

[0064] Furthermore, the width of the first light-shielding bar 40 and the spacing between two adjacent first light-shielding bars 40 can be set by setting the width of the first convergence section 50, the spacing between two adjacent first convergence sections 50, and the number of selected first wirings 201 among the selected first wirings of one grape corresponding to each first convergence section 50.

[0065] Let's assume that the lower limit of the distance e between two adjacent first light-shielding bars 40 is e1 and the upper limit is e2. By setting the distance e between two adjacent first light-shielding bars 40 to be greater than or equal to its lower limit e1, it is possible to avoid the diffraction phenomenon of light that can occur when light rays pass through the gaps between multiple first light-shielding bars 40 due to the distance e between two adjacent first light-shielding bars 40 being too small. By setting the distance e between two adjacent first light-shielding bars 40 to be less than or equal to its upper limit e2, it is possible to avoid a decrease in the number of first light-shielding bars 40 due to the distance e between two adjacent first light-shielding bars 40 being too large (if the area of ​​the sensing member region C1 is constant, the number of first light-shielding bars 40 decreases when the distance e between two adjacent first light-shielding bars 40 is too large), and thus avoid a decrease in the number of first convergence sections 50 corresponding to the first light-shielding bars 40. For the array substrate 131, the number of first wirings 20 is constant, and the number of selected first wirings 201 passing through the sensitive member region C1 is also constant. As a result, the number of selected first wirings 201 in each group corresponding to each first convergence section 50 increases, and the selected first wirings 201 in each group influence each other, which may cause fluctuations or inaccuracies in the transmitted signal.

[0066] Furthermore, let's assume that the lower limit of the width d of one first light-shielding bar 40 is d1 and the upper limit is d2. By setting the width d of one first light-shielding bar 40 to be greater than or equal to its lower limit d1, it is possible to avoid the problem that the width d of the first light-shielding bar 40 is too small, and therefore the gap between two adjacent selected first wirings 201 in the first convergence section 50 cannot be effectively blocked. By setting the width d of one first light-shielding bar 40 to be less than or equal to its upper limit d2, it is possible to avoid the problem that the width d of the first light-shielding bar 40 is too large, and therefore the distance e between two adjacent first light-shielding bars 40 is too small, causing light diffraction phenomena or a decrease in the amount of light passing through the sensitive member region C1.

[0067] Based on this, in some embodiments, the ratio of the width d of one first light-shielding bar 40 to the distance e between two adjacent first light-shielding bars is greater than 0 and less than or equal to 0.5. For example, the ratio of the width d of one first light-shielding bar 40 to the distance e between two adjacent first light-shielding bars 40 may be 1 / 2 or 7.5 / 16.125, etc.

[0068] For example, if the ratio of the width d of one first light-shielding bar 40 to the distance e between two adjacent first light-shielding bars 40 is greater than 0 and less than or equal to 0.5, then the sum f of the width d of one first light-shielding bar 40 and the distance e between two adjacent first light-shielding bars 40 is 94.5 μm or more and 200 μm or less. For example, the sum f of the width d of one first light-shielding bar 40 and the distance e between two adjacent first light-shielding bars 40 may be 94.5 μm, 100 μm, or 200 μm, etc.

[0069] Furthermore, one first light-shielding bar 40 may extend beyond the boundary defined by the two outermost selected first wirings 201 in its corresponding first convergence section 50 on both opposing sides in the second direction, or it may align with the boundary defined by the two outermost selected first wirings 201 in its corresponding first convergence section 50.

[0070] In the embodiments described above in this disclosure, the ratio of the width d of one first light-shielding bar 40 to the distance e between two adjacent first light-shielding bars 40 is set to be greater than 0 and 0.5 or less, and the sum of the width d of one first light-shielding bar 40 to the distance e between two adjacent first light-shielding bars 40 is set to be 94.5 μm or more and 200 μm or less. This makes it possible to further reduce the diffraction phenomenon of light when a light ray passes through the sensitive member region C1, and to make the light ray information that the sensitive member 2 senses more accurate.

[0071] When the sensing element 2 is a front camera, the inventors of this disclosure have confirmed through testing and verification that when acquiring an image with the front camera, setting the ratio of the width d of one first light-shielding bar 40 to the distance e between two adjacent first light-shielding bars 40 to 7.5 / 16.125, and setting the sum of the width d of one first light-shielding bar 40 to the distance e between two adjacent first light-shielding bars 40 to 94.5 μm, the diffraction phenomenon caused by light rays is effectively reduced, and the resolution of the captured image is high.

[0072] In some embodiments of the present disclosure, the array substrate 131 has areas along the extending direction of the first light-shielding bar 40 where thin-film transistors are located and areas where thin-film transistors are not located. Therefore, when designing the first light-shielding bar 40, in some embodiments, the width of the first light-shielding bar 40 varies along the extending direction of the first light-shielding bar 40. For example, the width of the first light-shielding bar 40 is wider where thin-film transistors are located, and narrower where thin-film transistors are not located. In this way, the spacing between two adjacent first light-shielding bars 40 is increased at the locations where the width of the first light-shielding bar 40 is narrow, allowing more light rays to pass through the sensitive member region C1 and be detected by the sensitive member 2.

[0073] Furthermore, if the width of the first light-shielding bar 40 differs along the extending direction of the first light-shielding bar 40, the interval e between two adjacent first light-shielding bars 40 refers to the interval between two adjacent first light-shielding bars 40 at the same position in a direction perpendicular to the extending direction of the first light-shielding bar 40.

[0074] In other embodiments, the width of the same first light-shielding bar 40 is the same everywhere along the extending direction of the first light-shielding bar 40. This simplifies the manufacturing process of the first light-shielding bar 40 and improves manufacturing efficiency. In some examples, when the width of the same first light-shielding bar 40 is the same everywhere, the gap between two adjacent first light-shielding bars 40 along the extending direction of the first light-shielding bar 40 may be the same or different. In some other examples, when the width of each first light-shielding bar 40 is the same everywhere, the widths of multiple first light-shielding bars 40 are all the same, which simplifies the process and reduces the difficulty of the manufacturing process when producing the first light-shielding bars 40.

[0075] If the widths of the multiple first light-shielding sections 40 are all the same, by setting the number of multiple selected first wirings 201 corresponding to each first convergence section 50 to be the same and setting the spacing between two adjacent selected first wirings 201 in each group to be the same, the degree to which multiple selected first wirings 201 in each group influence each other can be made the same. This makes the influence of multiple groups of selected first wirings 201 on the transmitted light rays within the sensing member region C1 the same, and improves the accuracy of the light ray information collected by the sensing member 2.

[0076] In some embodiments, a single first wiring 20 includes one or more first sub-wirings 20a. Exemplarily, as shown in Figure 5A, a single first wiring 20 includes one first sub-wiring 20a. As shown in Figure 7, a single first wiring 20 includes two first sub-wirings 20a. When a single first wiring 20 includes multiple first sub-wirings 20a, the two adjacent first sub-wirings 20a are spaced apart from each other. Since the selected first wiring 201 is a wiring that passes through the sensitive member region C1 among the multiple first wirings 20 of the array substrate 131, the above embodiments also apply to each selected first wiring 201.

[0077] In some embodiments, when the first direction is the column direction, the first sub-wiring 20a included in one first wiring 20 is at least one of the following: a data line, an initialization signal line, a first power line (Vdd line), a second power line (Vss line), etc. In some embodiments, when the first direction is the row direction, the first sub-wiring 20a included in one first wiring 20 is at least one of the following: a gate line, a control line, a common voltage signal line, etc. Since the selected first wiring 201 is wiring that passes through the sensitive member area C1 of multiple first wirings 20 on the array substrate 131, the above embodiments also apply to each selected first wiring 201.

[0078] In some embodiments, when a single first wiring 20 includes multiple first sub-wirings 20a, the types of first sub-wirings 20a included in the first wiring 20 may be the same or different. For example, a single first wiring 20 may include two data lines. For example, a single first wiring 20 may include one data line and one Vdd line. Since the selected first wiring 201 is a wiring among multiple first wirings of the array substrate that passes through the sensitive member region C1, the above embodiments also apply to each selected first wiring 201.

[0079] In some embodiments, a row of subpixels is coupled to a first subwiring 20a. In this case, if a pixel dot 10 contains at least one subpixel, a row of pixel dots corresponds to at least one first subwiring. For example, as shown in Figure 5A, if a pixel dot 10 contains one subpixel, a row of pixel dots corresponds to one first subwiring 20a. Furthermore, for example, as shown in Figure 7, if a pixel dot 10 contains two subpixels, a row of pixel dots corresponds to two first subwirings 20a. Furthermore, for example, if a pixel dot 10 contains three subpixels, a row of pixel dots corresponds to three first subwirings 20a. Since the selected first wiring 201 is a wiring that passes through the sensitive member region C1 among a plurality of first wirings 10 of the array substrate, the above embodiments also apply to each selected first wiring 201.

[0080] For example, when one first wiring 20 is connected to a row of subpixels, the number of subpixels contained in a pixel dot 10 is related to the number of data lines contained in the first wiring 20 connected to that pixel dot 10. For instance, if a pixel dot 10 contains one subpixel, the first wiring 20 connected to that pixel dot 10 contains one data line; if a pixel dot 10 contains two subpixels, the first wiring 20 connected to that pixel dot 10 contains two data lines; and if a pixel dot 10 contains three subpixels, the first wiring 20 connected to that pixel dot 10 contains three data lines.

[0081] In view of the above, as shown in Figure 7, when a row of pixel dots corresponds to at least two first sub-wirings 20a, in each row of pixel dots passing through the sensing member region C1, each first sub-wiring 20a corresponding to the same row of pixel dots can be converged to the same convergence section 50. This makes the wiring arrangement within the sensing member region C1 more regular and further reduces the degree of diffraction of light rays passing through the region.

[0082] As further shown in Figure 4B, the array substrate further includes a plurality of second wirings 30 along a second direction intersecting the first direction. In the non-sensitive member region C2, the arrangement of the plurality of second wirings 30 extending in the second direction is also dense, and the spacing between two adjacent second wirings 30 is small. In particular, in display devices with high PPI, the arrangement density of the second wirings 30 is even higher. Thus, in the process in which light passes through the sensitive member region C1 and propagates between the display surface side of the display panel 13 and the sensitive member 2, because the spacing between two adjacent second wirings 30 is small, diffraction occurs when the light ray propagates through the gap between two adjacent first wirings 30, which may affect the accuracy of the light ray information sensed by the sensitive member 2.

[0083] In view of this, in some embodiments, as shown in Figures 8A and 8B, the array substrate 131 according to some embodiments of the present disclosure further includes a plurality of second wirings 30 extending in a second direction and at least one second light-shielding bar 60. Here, the first direction and the second direction intersect, for example, the first direction and the second direction are perpendicular to each other, and for example, the angle between the first direction and the second direction is acute. In the drawings of the present disclosure, the case where the first direction and the second direction are perpendicular to each other is used as an example.

[0084] The plurality of second wirings 30 are arranged with intervals between them, and of the plurality of second wirings 30, the wiring that passes through the sensing member region C1 is the selected second wiring 301, and the plurality of selected second wirings 301 are divided into at least one group, and the selected second wirings in each group include at least two adjacent selected second wirings 301, and each selected second wiring 301 of the selected second wirings in each group converges in the sensing member region C1 to form a second convergence section 70.

[0085] For example, as shown in Figure 8A, the second wirings numbered T1 to T4 are selected second wirings 301. Multiple selected second wirings 301 may be divided into two groups, each group of selected second wirings containing two adjacent selected second wirings 301, and the two selected second wirings 301 included in each group of selected second wirings converge in the sensing member region C1 to form one second convergence section 70, and thus the two groups of selected second wirings 301 converge in the sensing member region C1 to form two second convergence sections 70.

[0086] For example, as shown in Figure 8A, the selected second wirings 301 numbered T1 and T2 are converged as a group of selected second wirings to form one second convergence section 70 in the sensing member region C1, and the selected second wirings 301 numbered T3 and T4 are converged as a group of selected second wirings to form one second convergence section 70 in the sensing member region C1. Here, taking two selected second wirings 301 numbered T1 and T2 as an example, the selected second wiring 301 numbered T2 includes a first portion extending in the second direction and a second portion extending in the first direction, and the first and second portions are arranged alternately in sequence and are connected at the end. With this structure, the selected second wiring 301 numbered T2 approaches the selected second wiring 301 numbered T1 in the sensing member region C1 and forms a second convergence section 70. The second convergence section 70 can be understood to include a portion located in the sensitive member area C1 of the selected second wiring 301 numbered T1, and a portion located in the sensitive member area C1 of the selected second wiring 301 numbered T2. The structure of the other second convergence section 70 is the same as that of the second convergence section 70 described above, so its explanation is omitted here.

[0087] As shown in Figures 9A to 9C, at least one second light-shielding bar 60 is positioned on the side of the array substrate 131 away from or adjacent to the display surface side of the plurality of selected second wirings 301, and the orthographic projection on the display surface of each second light-shielding bar 60 (i.e., positioned on the display surface when the array substrate 131 is applied to the display panel) covers the orthographic projection on the display surface of the second convergence section 70.

[0088] In embodiments of the present disclosure, the position of at least one second light-shielding bar 60 relative to the plurality of second arrangements 30 is not limited, as long as the orthographic projection of each second light-shielding bar 60 on the display surface of the array substrate 131 covers the orthographic projection on the display surface of one second convergence section 70. This allows one second light-shielding bar 60 to shield the gap between at least two adjacent selected second wirings 301 of one second convergence section 70, thereby avoiding diffraction caused by light rays passing through the gap between the selected second wirings 301 of the second convergence section 70.

[0089] Illustratively, Figure 9B shows a case where at least one second light-shielding bar 60 is positioned on the side of the array substrate 131 of the plurality of selected second wirings 301 that is close to the display surface side, and at least one second light-shielding bar 60 is positioned on the side of the plurality of selected second wirings 301 that is away from the base substrate 80. Figure 9C shows a case where at least one second light-shielding bar 60 is positioned on the side of the array substrate 131 of the plurality of selected second wirings 301 that is away from the display surface side, and at least one second light-shielding bar 60 is positioned on the side of the plurality of selected second wirings 301 that is close to the base substrate 80.

[0090] In some embodiments, as shown in Figure 9B, the at least one second light-shielding bar 60 is positioned on the side of the array substrate 131 closest to the display surface side of the plurality of selected first wirings 201, and the at least one second light-shielding bar 60 is positioned on the side of the plurality of selected second wirings 301 away from the base substrate 80. Thus, the manufacturing of the second light-shielding bar 60 can utilize the manufacturing process of the light-shielding pattern for blocking the active layer of the thin-film transistors on the array substrate 131, eliminating the need to provide a separate process for manufacturing the second light-shielding bar 60 and simplifying the manufacturing process of the array substrate 131.

[0091] As shown in Figure 8B, at least one second light-shielding bar 60 is positioned on the side of the array substrate 131 away from or adjacent to the display surface side of the plurality of second wirings 301, and the orthographic projection of each second light-shielding bar 60 on the display surface covers the orthographic projection of the second convergence section 70 on the display surface. This means that the number of second light-shielding bars 60 is the same as the number of second convergence sections 70.

[0092] In the array substrate 131 according to the embodiment of the present disclosure, the selected second wirings 301 of the sensitive member region C1 are grouped together, and each group of selected second wirings includes at least two adjacent selected second wirings 301, and each selected second wiring 301 of each group of selected second wirings converges in the sensitive member region C1 to form a second convergence portion 70. This corresponds to bringing each selected second wiring 301 of each group of selected second wirings closer to each other in the sensitive member region, so that two adjacent selected second wirings 301 of each group become closer in the sensitive member region C1, while the distance between two adjacent second convergence portions 70 becomes greater, and the distance between two adjacent second convergence portions 70 is greater than the distance between two adjacent second wirings 30 in the non-sensitive member region C2.

[0093] Furthermore, by providing at least one second light-shielding bar 60, the gaps between at least two adjacent selected second wirings 301 in the second convergence section 70 are blocked, preventing light rays from passing through these gaps and preventing the occurrence of light diffraction phenomena caused by light rays passing through the gaps between at least two selected second wirings 301 in the second convergence section 70.

[0094] Thus, when a light ray passes through the transparent sensitive member region C1 of the array substrate 131, it passes through the space between two adjacent second light-shielding bars 60, and the distance between two adjacent second convergence sections 70 is greater than the distance between two adjacent second wirings 30 in the non-sensitive member region C2. In other words, in the transparent sensitive member region C1, the arrangement density of the multiple second convergence sections 70 formed after each selected second wiring 301 of each group converges (corresponding to the arrangement density of the multiple second light-shielding bars 60) is lower than the arrangement density when the multiple second wirings 30 do not converge. Therefore, when a light ray passes through the transparent sensitive member region C1, the diffraction phenomenon is further reduced, the influence of light diffraction on the brightness of the light is reduced, and the accuracy of the light ray information sensed by the sensitive member 2 is further improved.

[0095] Taking the example that the sensing element 2 is a front camera, the diffraction phenomenon is further reduced when light rays pass through the transparent sensing element region C1, thus further improving the imaging effect of the front camera and resulting in better brightness and resolution of the obtained image.

[0096] In some embodiments, as shown in Figure 8A, in the transparent sensitive member region C1 of the array substrate 131, the distance g between two adjacent second convergence sections 70 is greater than the distance k between two adjacent second wirings 30 in the non-sensitive member region C2. In each second convergence section 70, the distance h between two adjacent selected second wirings 301 is less than the distance k between two adjacent second wirings 30 in the non-sensitive member region C2.

[0097] In the above embodiment, the distance g between two adjacent second convergence sections 70 is greater than the distance k between two adjacent second wirings 30 in the non-sensitive member region C2. Here, the distance g between two adjacent second convergence sections 70 is the distance between the two closest selected second wirings 301 located in each of the two adjacent second convergence sections 70. As a result, the distance g between two adjacent second convergence sections 70 is greater than the distance k between two adjacent second wirings 30 in the non-sensitive member region C2, and accordingly, the distance between two adjacent second light-shielding bars 60 is greater than the distance b between two adjacent second wirings 30 in the non-sensitive member region C1, thereby reducing the diffraction phenomenon when light rays pass through the transparent sensitive member region C1.

[0098] Furthermore, in each second convergence section 70, the distance h between two adjacent selected second wirings 301 is smaller than the distance k between two adjacent selected second wirings 30 in the non-sensitive member region C2. As a result, in each second convergence section 70, two adjacent selected second wirings 301 are closer to each other, reducing the dimensions of the second convergence section 70 in the direction perpendicular to the extending direction of the second convergence section 70 (i.e., the width of the second convergence section 70), and ensuring that the distance between two adjacent second convergence sections 70 can be increased. This further reduces the diffraction phenomenon of light, and in the second convergence section 70, the width of the second light-shielding bar 60 for blocking the gap between at least two adjacent selected second wirings 301 can be narrowed, allowing more light rays to pass through.

[0099] In some embodiments, the number of selected second wirings 301 included in each group of selected second wirings is not limited, and each group of selected second wirings may include two selected second wirings 301, as shown in Figures 8A, 8B, and 9A to 9C. Each group of selected second wirings may include two or more selected second wirings 301, and exemplary, the number of selected second wirings 301 included in each group of selected second wirings 301 may be three, four, or five.

[0100] In some embodiments, the number of selected second wirings 301 included in the selected second wiring of each group is the same.

[0101] For example, the number of selected second wirings 301 included in each group of selected second wirings 301 is 2, or the number of selected second wirings 301 included in each group of selected second wirings 301 is 3, 4, or another number. The array substrate shown in Figure 8A shows the case where each group of selected second wirings 301 includes 2 selected second wirings 301, which makes it possible to make the widths of the multiple second convergence sections 70 corresponding to the multiple groups of selected second wirings 301 equal or nearly equal, and the widths of the second light-shielding bars 60 equal or nearly equal. As a result, the degree of reduction in light ray diffraction is made equal or nearly equal in each region of the sensitive member region C1, the light rays transmitted through each region of the sensitive member region C1 become uniform, and the accuracy of the light ray information sensed by the sensitive member 2 is further improved.

[0102] In some embodiments, the distance between two adjacent second convergence sections 70 is equal, and the gap between each adjacent pair of selected second wirings in each second convergence section 70 is equal.

[0103] For example, as shown in Figure 8A, the distance between two adjacent second convergence sections 70 is g in both cases. In each second convergence section 70, if each group of selected second wirings includes three or more selected second wirings 301, the distance between each pair of adjacent selected second wirings 301 is equal.

[0104] With this design, the spacing between two adjacent second convergence sections 70 is equal, so the spacing between two adjacent second light-shielding bars 60 is also equal or nearly equal, and in each second convergence section 70, the spacing between each adjacent pair of selected second wirings 301 is equal. In this way, the widths of all the second convergence sections 70 are equal, and the widths of the second light-shielding bars 60 are equal or nearly equal. As a result, the degree of reduction in light ray diffraction is equal or nearly equal in each region of the sensitive member region C1, the light rays transmitted through each region of the sensitive member region C1 become more uniform, and the accuracy of the light ray information sensed by the sensitive member 2 is further improved.

[0105] In some embodiments of this disclosure, the effect of reducing the diffraction phenomenon of light can be further enhanced by setting the width of one second light-shielding bar 60 and the distance between two adjacent second light-shielding bars 60 to an appropriate range.

[0106] Note that the width m of the second light-shielding bar 60 refers to the dimension of one second light-shielding bar 60 in a direction perpendicular to the extension direction of the second light-shielding bar 60, as shown in Figure 9A, and the spacing p between two adjacent second light-shielding bars 60 refers to the spacing between two adjacent second light-shielding bars 60 in a direction perpendicular to the extension direction of the second light-shielding bar 60. For example, if the extension direction of the second light-shielding bar 60 is the second direction, the width d of the second light-shielding bar 60 refers to the dimension of one second light-shielding bar 60 in a direction perpendicular to the first direction. The spacing p between two adjacent second light-shielding bars 60 refers to the spacing between two adjacent second light-shielding bars 60 in a direction perpendicular to the first direction.

[0107] Furthermore, the width of the second light-shielding bar 60 and the spacing between two adjacent second light-shielding bars 60 can be set by setting the width of the second convergence section 70, the spacing between two adjacent second convergence sections 70, and the number of selected first wirings 301 among the selected second wirings for one grape corresponding to each second convergence section 70.

[0108] Let p1 be the lower limit and p2 be the upper limit of the interval p between two adjacent second light-shielding bars 60.

[0109] By setting the distance p between two adjacent second light-shielding bars 60 to be greater than or equal to its lower limit p1, the diffraction phenomenon of light that occurs when light rays pass through the space between multiple second light-shielding bars 60 due to the distance p between two adjacent second light-shielding bars 60 being too small can be avoided. By setting the distance p between two adjacent second light-shielding bars 60 to be less than or equal to its upper limit p2, it is possible to avoid a decrease in the number of second light-shielding bars 60 due to the distance p between two adjacent second light-shielding bars 60 being too large (when the area of ​​the sensing member region C1 is constant, the number of second light-shielding bars 60 decreases if the distance p between two adjacent second light-shielding bars 60 is too large), and thus avoid a decrease in the number of second converging sections 70 corresponding to the second light-shielding bars 60. In the case of the array substrate 131, if the number of second wirings 30 is constant, the number of selected second wirings 301 passing through the sensitive member region C1 is also constant. Thus, the number of selected second wirings 301 in each group corresponding to each second convergence section 70 increases, and therefore the selected second wirings 301 in each group influence each other, which may cause fluctuations or inaccuracies in the transmitted signal.

[0110] Furthermore, let's assume that the lower limit of the width m of one second light-shielding bar 60 is m1 and the upper limit is m2. By setting the width m of one second light-shielding bar 60 to be greater than or equal to its lower limit m1, it is possible to avoid the problem that the width m of the second light-shielding bar 60 is too small, and therefore the gap between two adjacent selected second wirings 301 of the second convergence section 70 cannot be effectively blocked. By setting the width m of one second light-shielding bar 60 to be less than or equal to its upper limit m2, it is possible to avoid the problem that the width m of the second light-shielding bar 60 is too large, causing the distance p between two adjacent second light-shielding bars 60 to become too small, resulting in the occurrence of light diffraction and a decrease in the amount of light passing through the sensitive member region C1.

[0111] In view of this, in some embodiments, the ratio of the width m of one second light-shielding bar 60 to the distance p between two adjacent second light-shielding bars 60 is greater than 0 and less than or equal to 0.5. For example, the ratio of the width m of one second light-shielding bar 60 to the distance p between two adjacent second light-shielding bars 60 may be 1 / 2 or 7.5 / 16.125, etc.

[0112] For example, if the ratio of the width m of one second light-shielding bar 60 to the distance p between two adjacent second light-shielding bars 60 is greater than 0 and less than or equal to 0.5, then the sum (pitch) n of the width m of one second light-shielding bar 60 and the distance p between two adjacent second light-shielding bars 60 is 94.5 μm or more and 200 μm or less. For example, the sum n of the width m of one second light-shielding bar 60 and the distance p between two adjacent second light-shielding bars 60 may be 94.5 μm, 100 μm, 200 μm, etc.

[0113] Furthermore, one second light-shielding bar 60 may extend beyond the boundary defined by the two outermost selected second wirings 301 of its corresponding second convergence section 70 on both opposing sides in the first direction, or it may align with the boundary defined by the two outermost selected second wirings 301 of its corresponding second convergence section 70.

[0114] In the embodiments described above in this disclosure, the ratio of the width m of one second light-shielding bar 60 to the distance p between two adjacent second light-shielding bars 60 is greater than 0 and 0.5 or less, and the sum of the width m of one second light-shielding bar 60 and the distance p between two adjacent second light-shielding bars 60 is 94.5 μm or more and 200 μm or less. This makes it possible to further reduce the diffraction phenomenon of light when a light ray passes through the sensitive member region C1, and to make the light ray information sensed by the sensitive member 2 more accurate.

[0115] In some embodiments, the ratio of the width m of one second light-shielding bar 60 to the spacing p between two adjacent second light-shielding bars 60 is equal to the ratio of the width d of one first light-shielding bar 40 to the spacing e between two adjacent first light-shielding bars 40, and the sum n of the width m of one second light-shielding bar 60 and the spacing p between two adjacent second light-shielding bars 60 is equal to the sum f of the width d of one first light-shielding bar 40 and the spacing e between two adjacent first light-shielding bars 40, and the sum f of the width d of one first light-shielding bar 40 and the spacing e between two adjacent first light-shielding bars 40, and the sum n of the width m of one second light-shielding bar 60 and the spacing p between two adjacent second light-shielding bars 60 is greater than the sum f of the width d of one first light-shielding bar 40 and the spacing e between two adjacent first light-shielding bars 40. For example, in this case, the sum n of the width m of one second light-shielding bar 60 and the distance p between two second light-shielding bars 60 is 180 μm, and the sum f of the width d of one first light-shielding bar 40 and the distance e between two adjacent first light-shielding bars 40 is 120 μm.

[0116] In the array substrate 131 according to some embodiments of this disclosure, there are areas along the extending direction of the second light-shielding bar 60 where thin-film transistors are located and areas where thin-film transistors are not located. Therefore, when designing the second light-shielding bar 60, the width of the second light-shielding bar 60 varies along its extending direction. For example, the width of the second light-shielding bar 60 is wider where thin-film transistors are located, and narrower where thin-film transistors are not located. In this way, at positions where the width of the second light-shielding bar 60 is narrow, the spacing between two adjacent second light-shielding bars 60 is increased, allowing more light rays to pass through the sensitive member region C1 and be detected by the sensitive member 2.

[0117] Furthermore, if the width of the second light-shielding bar 60 differs along the extending direction of the second light-shielding bar 60, the interval e between two adjacent second light-shielding bars 60 refers to the interval between two adjacent second light-shielding bars 60 at the same position in a direction perpendicular to the extending direction of the second light-shielding bar 60.

[0118] In another embodiment, the width of the same second light-shielding bar 60 is the same everywhere along the extending direction of the second light-shielding bar 60. This simplifies the manufacturing process of the second light-shielding bar 60 and improves manufacturing efficiency. Exemplaryly, if the width of the same second light-shielding bar 60 is the same everywhere, the spacing between two adjacent second light-shielding bars 60 along the extending direction of the second light-shielding bar 60 may be the same or different. For example, if the width of each second light-shielding bar 60 is the same everywhere, then the widths of multiple second light-shielding bars 60 are all the same. In this way, the manufacturing process of the second light-shielding bar 60 is simplified and the difficulty of the process is reduced.

[0119] If the widths of the multiple second light-shielding sections 60 are all the same, by setting the number of multiple selected second wirings 301 corresponding to each second convergence section 70 to be the same and setting the spacing between two adjacent selected second wirings 301 in each group to be the same, the mutual influence between multiple selected second wirings 301 in each group can be made to be the same. This makes the influence of multiple groups of selected second wirings 301 within the sensing member region C1 on the transmitted light rays the same, and improves the accuracy of the light ray information collected by the sensing member 2.

[0120] In some embodiments, one second wiring 30 includes one or more second sub-wirings 30a. Exemplarily, as shown in Figure 8A, one second wiring 30 includes one second sub-wiring 30a. As shown in Figure 7A, one second wiring 30 includes two second sub-wirings 30a. When one second wiring 30 includes multiple second sub-wirings 30a, the two adjacent second sub-wirings 30a are spaced apart from each other. Since the second wiring 301 is a wiring that passes through the sensitive member region C1 among the multiple second wirings 30 of the array substrate 131, the above embodiments also apply to each selected second wiring 301.

[0121] In some embodiments, when the second direction is the row direction, the second sub-wiring 30a included in one second wiring 30 is at least one of the following: gate lines, control lines, common signal lines (Com lines), etc. In some other embodiments, when the second direction is the column direction, the second sub-wiring 30a included in one second wiring 30 is at least one of the following: data lines, initialization signal lines, first power lines (Vdd lines), second power lines (Vss lines), etc. Since the second wiring 301 is a wiring that passes through the sensitive member region C1 among the plurality of second wirings 30 of the array substrate 131, the above embodiments also apply to each selected second wiring 301.

[0122] In some embodiments, when a single second wiring 30 includes multiple second sub-wirings 30a, the types of second sub-wirings 30a included in the second wiring 30 may be the same or different. For example, a single second wiring 30 may include two gate lines. Alternatively, for example, a single second wiring 30 may include one gate line and one Vss line. Since the first wiring 201 is a wiring that passes through the sensitive member region C1 among the multiple second wirings 30 of the array substrate 131, the above embodiments also apply to each selected second wiring 301.

[0123] In some embodiments, the number of first sub-wires 20a included in one first wire 20 is the same as the number of second sub-wires 30a included in one second wire 30. For example, the number of first sub-wires 20a included in one first wire 20 is the same as the number of second sub-wires 30a included in one second wire 30 is the same as two. In some other embodiments, the number of first sub-wires 20a included in one first wire 20 is different from the number of second sub-wires 30a included in one second wire 30.

[0124] In some embodiments, at least one first light-shielding bar 40 of the array substrate 131 is in the same film layer and made of the same material as at least one second light-shielding bar 60. Thus, the at least one first light-shielding bar 40 and the at least one second light-shielding bar 60 can be formed in the same manufacturing process, simplifying the manufacturing process and saving steps. Furthermore, the at least one first light-shielding bar 40 and the at least one second light-shielding bar 60 may be formed in the same layer as the light-shielding pattern for blocking the active layer of the thin-film transistors on the array substrate 131. Thus, the manufacturing of the at least one first light-shielding bar 40 and the at least one second light-shielding bar 60 can utilize the manufacturing process of the light-shielding pattern, eliminating the need for a separate process for manufacturing the at least one first light-shielding bar 40 and the at least one second light-shielding bar 60, further simplifying the manufacturing process of the array substrate.

[0125] In embodiments of this disclosure, the material of the at least one first light-shielding bar 40 and the at least one second light-shielding bar 60 is not limited as long as it can perform the function of light shielding. Exemplaryly, the material of the at least one first light-shielding bar 40 and the at least one second light-shielding layer 60 is one of a light-impermeable material such as black ink, black resin, or metal. If the material of the at least one first light-shielding bar 40 is a conductive material such as metal, an insulating layer is provided between the at least one first light-shielding bar 40 and the plurality of selected first wirings 201 of the array substrate 131 to prevent electrical conduction between them. If the material of the at least one second light-shielding bar 60 is a conductive material such as metal, an insulating layer is provided between the at least one second light-shielding bar 60 and the plurality of selected second wirings 301 to prevent electrical conduction between them.

[0126] As shown in Figures 3A and 3B, some embodiments of the present disclosure provide a display panel 13 comprising an array substrate 131 as described in any of the embodiments described above.

[0127] The display panel 13 according to the embodiment of this disclosure may be a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), or a quantum dot light-emitting display panel (QLED).

[0128] If the display panel 300 is a liquid crystal display panel, the display panel 13 includes an array substrate 131, a color filter substrate, and a liquid crystal layer disposed between the color filter substrate and the array substrate 131.

[0129] If the display panel 13 is an organic electroluminescent display panel or a quantum dot electroluminescent display panel, the display panel 13 includes an array substrate 131 and a sealing layer that seals the array substrate 131. The array substrate 131 comprises thin-film transistors and light-emitting elements including an ANO, an emissive layer, and a cathode. The sealing layer may be a thin-film sealing layer or a substrate sealing layer.

[0130] As shown in Figure 4A, the display panel 13 according to the embodiment disclosed herein has a sensitive member area C1 and a non-sensitive member area C2. The non-sensitive member area C2 has a display function, and the sensitive member area C1 is transparent and has a display function. As can be seen from each of the embodiments described above, in the sensitive member area C1 of the array substrate 131 of the display panel 13, the first wiring 20 (or the first wiring 20 and the second wiring 30) passing through the sensitive member area C1 is designed to converge such that the distance between two adjacent first convergence sections 50 (or two adjacent first convergence sections 50 and two adjacent second convergence sections 70) is large, thereby reducing the diffraction phenomenon of light transmitted through the sensitive member area C1 and improving the accuracy of the light ray information sensed by the sensitive member 2.

[0131] As shown in Figure 4A, in some embodiments, the display panel 13 may further have a non-display area D, which may be, for example, an outer frame.

[0132] As shown in Figures 3A and 3B, some embodiments of the present disclosure provide a display device 300 comprising a display panel 13 and at least one sensitive member 2, where the display panel 13 is the display panel 13 provided in the above embodiments.

[0133] The at least one sensing element 2 is positioned on the non-display side of the display panel 13, and the orthographic projection of the at least one sensing element 2 on the display panel 13 is within the sensing element area C1 of the display panel 13. The sensing surface of each sensing element 2 is oriented toward the display panel 13. Exemplarily, the at least one sensing element 2 includes one or more of the following: a front camera, a light sensor, a 3D sensing module, etc.

[0134] For example, if the sensing element 2 is equipped with a front camera, the photosensitive surface of the front camera is directed towards the display panel 13, and an image of a subject located on the front side (i.e., the display surface side) of the display device 300 is captured via the sensing element area C1 of the display panel 13. For example, if the sensing element 2 is equipped with a light sensor, the photosensitive surface of the light sensor is directed towards the display panel 13, and light rays from the front side (i.e., the display surface side) of the display device 300 are detected via the sensing element area C1 of the display panel 13. For example, if the sensing element 2 is equipped with a 3D sensing module, the light-emitting surface and photosensitive surface of the 3D sensing module are directed towards the display panel 13, and light rays are emitted from the object located on the front side (i.e., the display surface side) of the display device 300 via the sensing element area C1 of the display panel 13, and the light rays reflected from the object are received to realize the detection of the object's 3D spatial structure.

[0135] In the above-described display device 300, when a light ray passes through the sensitive member area C1 of the display panel 13, it is not diffracted, or the degree of diffraction is relatively light, so the accuracy of the light ray information sensed by the at least one sensitive member 2 is improved. For example, if the at least one sensitive member 2 includes a front camera, the captured image has high brightness and good resolution.

[0136] In the above-described display device 300, the region facing the sensitive element 2, such as a front camera, i.e., the sensitive element region C1, has a relatively high light transmittance and relatively small light diffraction. Therefore, when this display device 300 is applied to a terminal such as a mobile phone or tablet, the screen occupancy rate of the terminal can be greatly improved, full-screen display can be achieved, and the photosensitive effect of the sensitive element 2 is not affected by light diffraction, or is only slightly affected by light diffraction.

[0137] The above description represents only specific embodiments of the Disclosure, and the scope of protection of the Disclosure is not limited to these. Any modifications or substitutions that a person skilled in the art can easily conceive of within the technical scope of the Disclosure shall be included within the scope of protection of the Disclosure. Accordingly, the scope of protection of the Disclosure shall be governed by the scope of rights set forth in the claims.

[0138] This application claims priority based on a Chinese patent application filed with the China National Patent Office on October 11, 2018, with application number 201811185860.1 and title "Display Panels and Display Devices," the entire contents of which are incorporated into this application by reference.
