[0023] Hereinafter, the technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the drawings. Of course, it should be understood that the embodiments described herein are only a part of the embodiments of the present disclosure, and are not all of the embodiments. All other embodiments that a person skilled in the art can obtain based on the embodiments in the present disclosure shall be within the scope of the present disclosure.

[0024] The display device according to the embodiments of the present disclosure may be applicable to any terminal having a display function, such as a mobile phone, a flat panel display, a computer, or a television monitor, and the display device may be any device capable of displaying images such as moving images (e.g., video), still images (e.g., still images), text, pictures, etc.

[0025] Hereinafter, the term "display surface side" refers to the side of a display device or display panel that displays images, and the term "non-display panel side" refers to the side opposite to the display surface side of the display device or display panel.

[0026] In some embodiments, the display device includes a sensor, and the terminal to which the display device is applied is a mobile phone as an example. The display device includes a sensor such as a front camera, a light sensor, a 3D sensing module, etc., and these sensor elements need to sense light from the display surface side of the display device to realize corresponding functions. For example, when taking an image, the front camera of a mobile phone needs to collect light from an object located in front of the mobile phone (i.e., the display surface side) to realize the image.

[0027] In one related technology, as shown in Figures 1A and 1B, a display panel 11 of a display device 100 has a display area A1 and a non-display area B1, a hole is drilled in the display panel 11, and a sensor member 2 (e.g., a front camera) is embedded in the drilled hole, so that the sensor member 2 can sense light rays from the display surface side of the display panel 11.

[0028] 2A and 2B, in another related technology, the display panel 12 of the display device 200 has a display area A2 and a transparent area B2, and the sensitive member 2 is disposed on the non-display side of the display panel 12 of the display device 200, and the sensitive member 2 faces the transparent area B2 of the display panel 12, that is, the orthogonal projection of the sensitive member 2 on the display surface of the display panel 12 is within the transparent area B2. Thus, light from the display surface side of the display panel 12 is transmitted through the transparent area B2 and sensed by the sensitive member 2.

[0029] In both of the above-mentioned two arrangement methods of the sensor member 2, there are areas on the display surface of the display panel that cannot be displayed, the screen occupancy rate of the display device is reduced, and the ratio of the area of ​​the display area of ​​the display panel to the total area of ​​the display panel is not 100 percent, making it impossible to realize full-surface display.

[0030] In order to achieve a higher screen occupancy rate, in some embodiments of the present disclosure, as shown in Figures 3A and 3B, a display device 300 includes 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, and the non-sensitive member area C2 is capable of displaying an image; the non-sensitive member area C2 may, for example, be transparent and surround the sensitive member area C1 capable of displaying an image, or may surround half of the sensitive member area C1. The sensitive member 2 is disposed on the non-display side of the display panel 13, and faces the sensitive member area C1 of the display panel 13, that is, the orthogonal projection of the sensitive member 2 on the display surface of the display panel 13 is within the sensitive member area C1.

[0031] The sensitive surface of the sensitive member 2 faces the display panel 13. Since the sensitive member area C1 is transparent, the sensitive member 2 can sense light rays from the display surface side of the display panel 13 through the sensitive member area C1 and perform a corresponding operation. For example, in the case where the sensitive member 2 is a front camera, the front camera captures light rays from an object on the display surface side of the display panel 13 through the sensitive member area C1, forms an image, and captures an image of the object.

[0032] In order to increase the light transmittance of the sensitive member area C1 and allow the sensitive member 2 arranged on the non-display side of the display panel 13 to transmit through the sensitive member area C1 and sense more light from the display surface side of the display panel 1, as shown in Figures 4A and 4B, in some embodiments, the display panel 13 is designed so 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.

[0033] In order to more clearly explain the technical solution of the present disclosure, a region E is defined from the display surface of the display panel 13, and the configuration in region E is described below, with FIG. 4B being an enlarged structural diagram of region E. Region E includes a part of non-sensitive member region C2 and sensitive member region C1. The "part of non-sensitive member region C2" refers to a region of non-sensitive member region C2 that is adjacent to sensitive member region C1 and located around sensitive member region C1. The structure of the region of non-sensitive member region C2 located outside region E may be understood by reference to the structure of a part of non-sensitive member region C2 located within region E.

[0034] A method is adopted to reduce the PPI (Pixels Per Inch) of the sensitive member area C1, that is, by reducing the number of pixel dots 10 in the sensitive member area C1 compared to the non-sensitive member area C2, the space occupied by the pixel dots 10 in the sensitive member area C1 is reduced, leaving space for light to pass through, thereby giving the sensitive member area C1 a high light transmittance.

[0035] However, through research by the inventors of the present disclosure, the following was discovered.

[0036] As shown in FIG. 4B, in the display area of ​​the display panel 13 (for example, the area E including a part of the non-sensitive member area C2 and the sensitive member area C1), a plurality of first wirings 20 extending in a first direction and a plurality of second wirings 30 extending in a second direction are provided, and the plurality of first traces 20 are provided at intervals, and the plurality of second traces 30 are also provided at intervals. The first direction and the second direction intersect, and for example, the first direction is the column direction in which the plurality of pixel dots 10 are arranged, and the second direction is the row direction in which the 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 wirings include data lines (Data lines), initialization signal lines, first power lines (Vdd lines), second power lines (Vss lines), etc., and the second wirings include gate lines (Gate lines), control lines, common voltage signal lines (Com lines), etc. Since the PPI of the non-sensitive member region C2 is high, the first wirings 20 are arranged densely and the interval between two adjacent first wirings 20 is small.

[0037] The arrangement density of the first wiring 20 in the sensory member region C1 is the same as that in the non-sensitive member region C2. This is because, for each subpixel row in which a plurality of pixel dots 10 in the sensory member region C1 are located, the PPI of the C22 region and the C24 region in the non-sensitive member region C2 of the subpixel row matches the PPI of the C21 region and the C23 region in the non-sensitive member region C2. Therefore, since the arrangement density of the first wiring 20 and the second wiring 30 in the C22 region and the C24 region in the non-sensitive member region C2 matches the arrangement density of the first wiring 20 and the second wiring 30 in the C21 region and the C23 region in the non-sensitive member region C2, the wiring density in the sensory member region C1 of these subpixel rows does not decrease due to a decrease in the PPI.

[0038] Thus, in the process of light passing through the sensor region C1 and propagating between the display surface side of the display panel 13 and the sensor region 2, the multiple first wirings 20 in the sensor region C1 are densely arranged and the interval between two adjacent first wirings 20 is small, so that when the light passes through the gap between the two adjacent first wirings 20 and propagates, a diffraction phenomenon occurs, which may affect the accuracy of the light information sensed by the sensor region. Here, the light diffraction phenomenon refers to the phenomenon in which, when light hits an obstacle or a small hole during the propagation process, the light propagates around the obstacle instead of the linear propagation path. The smaller the interval between the obstacles and the smaller the small hole, the more prominent the diffraction phenomenon becomes. When the linearity of the small hole is small enough to be comparable to the light wavelength, the light diffraction phenomenon becomes extremely severe, and the diffraction phenomenon occurring during the propagation of light becomes prominent, causing the light to become dark.

[0039] For example, taking the sensor element 2 as a front camera, when the front camera captures an image through the sensor element area C1 of the display panel 13, the front camera needs to capture the light beam of the subject located on the display surface side of the display panel 13 through the sensor element area C1. However, because the first wiring 20 is densely arranged, optical diffraction occurs when the light beam passes through the sensor element area C1, and the light beam information collected by the front camera becomes inaccurate, thereby reducing the imaging effect of the front camera, resulting in problems such as low image brightness and poor resolution.

[0040] In view of the above, some embodiments of the present disclosure provide an array substrate 131 having a non-sensitive member area C2 and a transparent sensitive member area C1, as shown in Figures 5A and 5B. The sensitive member area C1 and the non-sensitive member area C2 all have display functions, and the non-sensitive member area C2 may, for example, surround the sensitive member area C1 or half surround the sensitive member area C1.

[0041] The array substrate 131 has a non-sensitive member region C2 and a transparent sensitive member region C1, and when the array substrate 131 is applied to a display device including a sensitive member 2, light can pass through the transparent sensitive member region C1 to propagate between the display surface side of the array substrate 131 and the sensitive element 2, i.e., light from the display surface side can pass through the sensitive member region C1 and be sensed by the sensitive member 2.

[0042] 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 from one another, and among the plurality of first wirings 20, the wirings passing through the sensitive member region C1 are selected first wirings 201; the plurality of selected first wirings 201 are divided into at least one group, and each selected first wiring of each group includes at least two adjacent selected first wirings 201, and each selected first wiring of each group converges in the sensitive member region C1 to form a first convergence portion 50.

[0043] 5A, the first wirings with numbers L1 to L6 are selected first wirings 201. The selected first wirings 201 may be divided into three groups, and each group of selected first wirings includes two adjacent selected first wirings 201, and the two selected first wirings 201 included in each group of selected first wirings converge in the sensitive member region C1 to form one first convergence portion 50, so that the three groups of selected first wirings 201 converge in the sensitive member region C1 to form three first convergence portions 50.

[0044] For example, as further shown in FIG. 5A, the selected first wirings 201 numbered L1 and L2 converge as the selected first wirings of one grape within the sensitive member area C1 to form the first converging portion 50; the selected first wirings 201 numbered L3 and L4 converge as the selected first wirings of one grape within the sensitive member area C1 to form the first converging portion 50; and the selected first wirings 201 numbered L5 and L6 converge as the selected first wirings of one grape within the sensitive member area C1 to form the first converging portion 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, and the first portion and the second portion are arranged alternately and connected in sequence, and with this structure, the selected first wiring 201 numbered L2 approaches the selected first wiring 201 numbered L1 in the sensitive member area C1 to form one first convergence portion 50. It can be understood that the first convergence portion 50 includes a portion of the selected first wiring 201 numbered L1 located in the sensitive member area C1 and a portion of the selected first wiring 201 numbered L2 located in the sensitive member area C1. The structures of the other two first convergence portions 50 are similar to the structure of the first convergence portion 50 described above, and therefore will not be described here.

[0045] 6A to 6C, the array substrate 131 further includes at least one first light-shielding bar 40. The at least one first light-shielding bar 40 is disposed on a side of the plurality of selected first wirings 201 that is away from or close to the display surface side of the array substrate 131, and the orthogonal projection of each first light-shielding bar 40 on the display surface of the array substrate 131 (i.e., when the array substrate 131 is applied to a display panel, it is disposed on the surface on which display is performed) covers the orthogonal projection of one first converging portion 50 on the display surface.

[0046] The embodiment of the present disclosure does 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 orthogonal projection of each first light-shielding bar 40 on the display surface of the array substrate 131 covers the orthogonal projection of one first converging portion 50 on the display surface. In this way, one first light-shielding bar 40 can shield the gap between at least two adjacent selected first wirings 201 of one first converging portion 50, and avoid diffraction caused by light transmitting through the gap between the selected first wirings 201 of the first converging portion 50.

[0047] 6B illustrates a case where the at least one first light-shielding bar 40 is disposed on a side of the selected first wirings 201 that is close to the display surface side of the array substrate 131, and the at least one first light-shielding bar 40 is disposed on a side of the selected first wirings 201 that is away from the base substrate 80. FIG. 6C illustrates a case where the at least one first light-shielding bar 40 is disposed on a side of the selected first wirings 201 that is away from the display surface side of the array substrate 131, and the at least one first light-shielding bar 40 is disposed on a side of the selected first wirings 201 that is close to the base substrate 80.

[0048] In some embodiments, as shown in FIG. 6B , the at least one first shading bar 40 is arranged on a side of the plurality of selected first wirings 201 that is close to the display surface side of the array substrate 131, and the at least one first shading bar 40 is arranged on a side of the plurality of selected first wirings 201 that is away from the base substrate 80. Thus, the manufacturing process of the shading pattern for blocking the active layer of the thin film transistor in the array substrate 131 can be reused for manufacturing the first shading bar 40, and there is no need to set up a separate process for manufacturing the first shading bar 40, which can simplify the manufacturing process of the array substrate 131.

[0049] 5B, the at least one first light-shielding bar 40 is disposed on a side of the selected first wirings 201 that is away from or close to the display surface side of the array substrate 131, and the orthogonal projection of each first light-shielding bar 50 on the display surface covers the orthogonal projection of the first converging portion 50 on the display surface. This means that the number of the first light-shielding bars 50 is the same as the number of the first converging portions 50.

[0050] In the array substrate 131 according to the embodiment of the present disclosure, the selected first wirings 201 in the sensitive member region C1 are grouped, and each group of the selected first wirings 201 includes at least two adjacent selected first wirings 201, and each selected first wiring 201 of the selected first wirings in each group converges in the sensitive member region C1 to form a first convergent portion 50. This corresponds to each selected first wiring 201 of the selected first wirings in each group approaching each other in the sensitive member region C1, so that two adjacent selected first wirings 201 of the selected first wirings in each group are closer to each other in the sensitive member region C1, while the distance between two adjacent first convergent portions 50 is greater, and the distance between two adjacent first convergent portions 50 is greater than the distance between two adjacent first wirings 20 in the non-sensitive member region C2.

[0051] 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 converging portion 50 are blocked, blocking the transmission of light through these gaps, and preventing the occurrence of the light diffraction phenomenon due to the transmission of light through the gaps between the at least two selected first wirings 201 in the first converging portion 50.

[0052] Thus, when the light passes through the transparent sensor region C1 of the array substrate 131, it passes through the space between two adjacent first light-shielding bars 40. The interval between two adjacent first converging portions 50 is greater than the interval between two adjacent first wires 20 in the non-sensitive member region C2, that is, in the transparent sensor region C1, the arrangement density of the first converging portions 50 (corresponding to the arrangement density of the first light-shielding bars 40) formed after the selected first wires 201 of each group of the selected first wires converge is lower than the arrangement density when the first wires 20 do not converge, so that the diffraction phenomenon is reduced when the light passes through the transparent sensor region C1, the effect of the diffraction of light on the light brightness is reduced, and the accuracy of the light information sensed by the sensor 2 is improved.

[0053] For example, taking the sensor element 2 as a front camera, when light passes through the transparent sensor element area C1, the diffraction phenomenon is reduced, improving the imaging effect of the front camera and greatly improving the brightness and resolution of the obtained image.

[0054] 5A, in the transparent sensitive member region C1 of the array substrate 131, the distance a between two adjacent first converging portions 50 is greater than the distance b between two adjacent first wires in the non-sensitive member region C2. In each first converging portion 50, the distance c between two adjacent selected first wires 201 is less than the distance b between two adjacent first wires in the non-sensitive member region C2.

[0055] In the above embodiment, the distance a between two adjacent first converging portions 50 is greater than the distance b between two adjacent first wirings 20 in the non-sensitive member region C2, and the distance a between two adjacent first converging portions 50 is the distance between two selected first wirings 201 located in the two adjacent first converging portions 50 and closest to each other. Thus, the distance a between two adjacent first converging portions 50 is greater than the distance b between two adjacent first wirings 20 located in the non-sensitive member region C2. Correspondingly, the distance between two adjacent first light-shielding bars 40 is greater than the distance b between two adjacent first wirings 20 in the non-sensitive member region C2. As a result, the diffraction phenomenon is reduced when the light passes through the transparent sensitive member region C1.

[0056] In addition, in each first converging portion 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. Therefore, in each first converging portion 50, the two adjacent selected first wirings 201 are closer to each other, and the dimension of the first converging portion 50 in the direction perpendicular to the extension direction of the first converging portion 50 (i.e., the width of the first converging portion 50) is reduced, ensuring that the distance between the two adjacent first converging portions 50 is increased. This reduces the light diffraction phenomenon and narrows the width of the first light-shielding bar 40 for blocking the gap between at least two adjacent selected first wirings 201 in the first converging portion 50, allowing more light to pass through the sensitive member region C1.

[0057] In some embodiments, the number of selected first wirings 201 included in the selected first wirings of each group is not limited, and the selected first wirings of each group may include two selected first wirings 201, as shown in Figures 5A, 5B, and 6A to 6C. Alternatively, the selected first wirings of each group may include two or more selected first wirings 201, and for example, the number of selected first wirings 201 included in the selected first wirings 201 of each group is three, four, or five.

[0058] In some embodiments, the number of selected first wirings 201 included in the selected first wirings of each group is the same.

[0059] For example, the number of the selected first wirings 201 included in the selected first wirings of each group is two, or the number of the selected first wirings 201 included in the selected first wirings of each group is three, four, or other numbers. Fig. 5A shows a case where the selected first wirings of each group include two selected first wirings 201, so that the widths of the multiple first converging parts 50 corresponding to the selected first wirings of multiple groups are all equal or approximately equal, and the widths of the first light-shielding bars 40 are equal or approximately equal, so that the degree of diffraction reduction of the light beam in each region of the sensitive member region C1 is equal or approximately equal, and the light beam passing through each region of the sensitive member region C1 is uniform, thereby further improving the accuracy of the light beam information sensed by the sensitive member 2.

[0060] In some embodiments, the intervals between two adjacent first convergent portions 50 are equal. In each first convergent portion 50, the gaps between each two adjacent selected first wirings 201 are equal.

[0061] 5A, the interval between any two adjacent first convergence portions 50 is a. In each first convergence portion 50, when each selected first wiring includes three or more selected first wirings 201, the interval between each two adjacent selected first wirings 201 is equal.

[0062] With this design, the intervals between two adjacent first converging portions 50 are equal, and therefore the intervals between two adjacent first shading bars 40 are equal or nearly equal. In each first converging portion 50, the intervals between each two adjacent selected first wirings 201 are equal, so that the widths of the first converging portions 50 are all equal, and the widths of the first shading bars 40 are equal or nearly equal, so that the degree of reduction in the diffraction of the light beam in each region of the sensitive member region C1 is equal or nearly equal, and the light beam passing through each region of the sensitive member region C1 is more uniform, thereby improving the accuracy of the light beam information sensed by the sensitive member 2.

[0063] In some embodiments of the present disclosure, the effect of reducing the light diffraction phenomenon can be further improved by setting the width of the first light-shielding bar 40 and the interval between two adjacent first light-shielding bars 40 within an appropriate range.

[0064] 6A, 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 extension 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 in a direction perpendicular to the extension direction of the first light-shielding bars 40. Exemplarily, when the extension direction of the first light-shielding bars 40 is a 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 interval e between two adjacent first light-shielding bars 40 refers to the interval between two adjacent first light-shielding bars 40 in a direction perpendicular to the first direction.

[0065] Furthermore, the width of the first shading bar 40 and the spacing between two adjacent first shading bars 40 can be set by setting the width of the first converging portion 50, the spacing between two adjacent first converging portions 50, and the number of selected first wirings 201 among the selected first wirings of one grape corresponding to each converging portion 50.

[0066] Assume that the lower limit value of the interval e between two adjacent first light-shielding bars 40 is e1 and the upper limit value is e2. By setting the interval e between two adjacent first light-shielding bars 40 to be equal to or greater than the lower limit value e1, it is possible to avoid the light diffraction phenomenon that may occur when light passes through the gaps between the first light-shielding bars 40 because the interval e between two adjacent first light-shielding bars 40 is too small. By setting the interval e between two adjacent first light-shielding bars 40 to be equal to or less than the upper limit value e2, it is possible to avoid the number of first light-shielding bars 40 being reduced because the interval e between two adjacent first light-shielding bars 40 is too large (when the area of ​​the sensitive member region C1 is constant, if the interval e between two adjacent first light-shielding bars 40 is too large, the number of first light-shielding bars 40 will be reduced), and thus the number of first converging portions 50 corresponding to the first light-shielding bars 40 will be reduced. For the array substrate 131, the number of first wirings 20 is fixed, and the number of selected first wirings 201 passing through the sensitive member area C1 is also fixed. Thus, the number of selected first wirings 201 in each group corresponding to each first converging portion 50 becomes large, and the selected first wirings 201 of each group may affect each other, which may cause fluctuations or inaccuracies in the transmitted signals.

[0067] Also, assume that the lower limit value of the width d of one first light-shielding bar 40 is d1 and the upper limit value is d2. By setting the width d of one first light-shielding bar 40 to be equal to or greater than the lower limit value d1, it is possible to avoid a problem in which the width d of the first light-shielding bar 40 is too small and therefore the gap between two adjacent selected first wirings 201 cannot be effectively blocked in the first converging portion 50. By setting the width d of one first light-shielding bar 40 to be equal to or less than the upper limit value d2, it is possible to avoid a problem in which the width d of the first light-shielding bar 40 is too large and therefore the interval e between two adjacent first light-shielding bars 40 is too small, resulting in light diffraction phenomenon and a decrease in the amount of light passing through the sensitive member region C1.

[0068] Based on this, in some embodiments, the ratio of the width d of one first light-shielding bar 40 to the spacing 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 spacing e between two adjacent first light-shielding bars 40 may be 1 / 2 or 7.5 / 16.125, etc.

[0069] Exemplarily, when the ratio of the width d of one first light-shielding bar 40 to the interval e between two adjacent first light-shielding bars 40 is greater than 0 and equal to or less than 0.5, the sum f of the width d of one first light-shielding bar 40 to the interval e between two adjacent first light-shielding bars 40 is equal to or greater than 94.5 μm and equal to or less than 200 μm. For example, the sum f of the width d of one first light-shielding bar 40 to the interval e between two adjacent first light-shielding bars 40 may be 94.5 μm, 100 μm, or 200 μm, etc.

[0070] In addition, both opposing sides of one first shading bar 40 in the second direction may extend beyond the boundary defined by the two outermost selected first wirings 201 in its corresponding first converging portion 50, or may be aligned with the boundary defined by the two outermost selected first wirings 201 in its corresponding first converging portion 50.

[0071] In the above-mentioned embodiments of the present disclosure, the ratio of the width d of one first shading bar 40 to the spacing e between two adjacent first shading bars 40 is greater than 0 and not more than 0.5, and the sum of the width d of one first shading bar 40 and the spacing e between two adjacent first shading bars 40 is greater than 94.5 μm and not more than 200 μm, so that the light diffraction phenomenon can be further reduced when the light passes through the sensitive member area C1, and the light information sensed by the sensitive member 2 can be more accurate.

[0072] When the sensor member 2 is a front camera, the inventors of the present disclosure have confirmed through testing and verification that when capturing an image with a front camera, by setting the ratio of the width d of one first shading bar 40 to the distance e between two adjacent first shading bars 40 to 7.5 / 16.125, and setting the sum of the width d of one first shading bar 40 to the distance e between two adjacent first shading bars 40 to 94.5 μm, the diffraction phenomenon caused by light can be effectively reduced, and the resolution of the captured image can be high.

[0073] In the array substrate 131 according to some embodiments of the present disclosure, there are areas along the extension direction of the first light-shielding bar 40 where thin film transistors are arranged and areas where thin film transistors are not arranged, so when designing the first light-shielding bar 40, in some embodiments, the width of the first light-shielding bar 40 is different along the extension direction of the first light-shielding bar 40, for example, the width of the first light-shielding bar 40 is wide at the areas where thin film transistors are arranged and the width of the first light-shielding bar 40 is narrow at the areas where thin film transistors are not arranged. Thus, at the areas where the width of the first light-shielding bar 40 is narrow, the gap between two adjacent first light-shielding bars 40 is wide, so that more light can pass through the sensitive member area C1 and be sensed by the sensitive member 2.

[0074] In addition, when the width of the first shading bars 40 varies along the extension direction of the first shading bars 40, the distance e between two adjacent first shading bars 40 refers to the distance between the same positions of two adjacent first shading bars 40 in a direction perpendicular to the extension direction of the first shading bars 40.

[0075] In another embodiment, the width of the same first light-shielding bar 40 is the same everywhere along the extension direction of the first light-shielding bar 40. In this way, the manufacturing process of the first light-shielding bar 40 can be simplified and the manufacturing efficiency can be improved. 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 extension direction of the first light-shielding bar 40 can be the same or different. In other examples, when the width of each first light-shielding bar 40 is the same everywhere, the widths of the multiple first light-shielding bars 40 are all the same, so that the process of manufacturing the first light-shielding bar 40 can be simplified and the difficulty of the process can be reduced.

[0076] When the multiple first light-shielding portions 40 all have the same width, the number of multiple selected first wirings 201 corresponding to each first converging portion 50 can be set to be equal, and the distance between two adjacent selected first wirings 201 among the selected first wirings of each group can be set to be equal, so that the degree to which the multiple selected first wirings 201 among the selected first wirings of each group influence each other can be made equal, thereby making the influence of the multiple groups of selected first wirings 201 on the transmitted light in the sensory member area C1 equal, and improving the accuracy of the light information collected by the sensory member 2.

[0077] In some embodiments, one first wiring 20 includes one or more first sub-wirings 20a. Exemplarily, as shown in FIG. 5A, one first wiring 20 includes one first sub-wiring 20a. As shown in FIG. 7, one first wiring 20 includes two first sub-wirings 20a. When one 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-mentioned embodiment is similarly applied to each selected first wiring 201.

[0078] In some embodiments, when the first direction is the column direction, the first sub-wire 20a included in one first wiring 20 is at least one of a data line, an initialization signal line, a first power supply line (Vdd line), a second power supply line (Vss line), etc. In some embodiments, when the first direction is the row direction, the first sub-wire 20a included in one first wiring 20 is at least one of a gate line, a control line, a common voltage signal line, etc. Since the selected first wiring 201 is a wiring passing through the sensitive member region C1 of the multiple first wirings 20 of the array substrate 131, the above-mentioned embodiments are similarly applied to each selected first wiring 201.

[0079] In some embodiments, when one first wiring 20 includes multiple first sub-wirings 20a, the types of the first sub-wirings 20a included in the first wiring 20 may be the same or different. For example, one first wiring 20 includes two data lines. For example, one first wiring 20 includes one data line and one Vdd line. The selected first wiring 201 is a wiring that passes through the sensitive member region C1 among the multiple first wirings of the array substrate, so the above-mentioned embodiments are similarly applied to each selected first wiring 201.

[0080] In some embodiments, the sub-pixels in one column are coupled to one first sub-wire 20a. In this case, when one pixel dot 10 includes at least one sub-pixel, the pixel dots in one column correspond to at least one first sub-wire. For example, as shown in FIG. 5A, when one pixel dot 10 includes one sub-pixel, the pixel dots in one column correspond to one first sub-wire 20a. For example, as shown in FIG. 7, when one pixel dot 10 includes two sub-pixels, the pixel dots in one column correspond to two first sub-wires 20a. For example, when one pixel dot 10 includes three sub-pixels, the pixel dots in one column correspond to three first sub-wires 20a. The selected first wire 201 is a wire that passes through the sensitive member region C1 among the multiple first wires 10 of the array substrate, so the above-mentioned embodiment is similarly applied to each selected first wire 201.

[0081] For example, when one first wiring 20 is coupled to one column of subpixels, the number of subpixels included in one pixel dot 10 is related to the number of data lines included in the first wiring 20 coupled to the pixel dot 10. For example, when one pixel dot 10 includes one subpixel, the first wiring 20 coupled to the pixel dot 10 includes one data line; when one pixel dot 10 includes two subpixels, the first wiring 20 coupled to the pixel dot 10 includes two data lines; when one pixel dot 10 includes three subpixels, the first wiring 20 coupled to the pixel dot 10 includes three data lines.

[0082] In view of the above, as shown in FIG. 7, when a column of pixel dots corresponds to at least two first sub-wires 20a, in each column of pixel dots passing through the sensory member region C1, each first sub-wire 20a corresponding to the pixel dots in the same column can be converged to the same converging portion 50, thereby making the wiring arrangement in the sensory member region C1 more regular and further reducing the degree of diffraction of light passing through the region.

[0083] As further shown in FIG. 4B, the array substrate further includes a plurality of second wirings 30 along a second direction intersecting with 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 interval between two adjacent second wirings 30 is small. In particular, in a display device with a high PPI, the arrangement density of the second wirings 30 is 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, the interval between the two adjacent second wirings 30 is small, so that a diffraction phenomenon occurs when the light propagates through the gap between the two adjacent first wirings 30, which may affect the accuracy of the light information sensed by the sensitive member 2.

[0084] In view of this, in some embodiments, as shown in Figures 8A and 8B, an 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 an acute angle. In the drawings of the present disclosure, it is taken as an example that the first direction and the second direction are perpendicular to each other.

[0085] The plurality of second wirings 30 are arranged at intervals, and among the plurality of second wirings 30, those that pass through the sensory member region C1 are selected second wirings 301, and the plurality of selected second wirings 301 are divided into at least one group, and the selected second wirings of each group include at least two adjacent selected second wirings 301, and each selected second wiring 301 of the selected second wirings of each group converges in the sensory member region C1 to form a second convergence portion 70.

[0086] 8A, the second wirings numbered T1 to T4 are selected second wirings 301. The selected second wirings 301 may be divided into two groups, and the selected second wirings of each group include two adjacent selected second wirings 301, and the two selected second wirings 301 included in the selected second wirings of each group converge in the sensitive member region C1 to form one second convergence portion 70, and thus the selected second wirings 301 of the two groups converge in the sensitive member region C1 to form two second convergence portions 70.

[0087] For example, as shown in FIG. 8A, the selected second wires 301 with numbers T1 and T2 are converged to form one second convergent portion 70 in the sensitive member region C1 as one group of selected second wires, and the selected second wires 301 with numbers T3 and T4 are converged to form one second convergent portion 70 in the sensitive member region C1 as one group of selected second wires. Here, taking two selected second wires 301 with numbers T1 and T2 as an example, the selected second wire 301 with number T2 includes a first portion extending in the second direction and a second portion extending in the first direction, and the first portion and the second portion are alternately arranged in sequence and are connected to each other. With this structure, the selected second wire 301 with number T2 approaches the selected second wire 301 with number T1 in the sensitive member region C1 to form the second convergent portion 70. The second converging portion 70 can be understood to include a portion of the selected second wiring 301 numbered T1 located in the sensitive member region C1 and a portion of the selected second wiring 301 numbered T2 located in the sensitive member region C1. The structure of the other second converging portion 70 is similar to the structure of the second converging portion 70 described above, and therefore a description thereof will be omitted here.

[0088] As shown in Figures 9A to 9C, at least one second shading bar 60 is arranged on the side away from or close to the display surface side of the array substrate 131 of the multiple selected second wirings 301, and the orthogonal projection of each second shading bar 60 on the display surface (i.e., arranged on the surface that displays when the array substrate 131 is applied to a display panel) covers the orthogonal projection of the second converging portion 70 on the display surface.

[0089] In the embodiment of the present disclosure, as long as the orthogonal projection of each second shading bar 60 on the display surface of the array substrate 131 covers the orthogonal projection of one second converging portion 70 on the display surface, the position of the at least one second shading bar 60 relative to the plurality of second arrangements 30 is not limited. In this way, one second shading bar 60 can shield the gap between at least two adjacent selected second wirings 301 of one second converging portion 70, and can avoid diffraction caused by light transmitting through the gap between the selected second wirings 301 of the second converging portion 70.

[0090] 9B illustrates a case where the at least one second light-shielding bar 60 is disposed on a side of the selected second wirings 301 that is close to the display surface side of the array substrate 131, and the at least one second light-shielding bar 60 is disposed on a side of the selected second wirings 301 that is away from the base substrate 80. FIG. 9C illustrates a case where the at least one second light-shielding bar 60 is disposed on a side of the selected second wirings 301 that is away from the display surface side of the array substrate 131, and the at least one second light-shielding bar 60 is disposed on a side of the selected second wirings 301 that is close to the base substrate 80.

[0091] 9B , the at least one second light-shielding bar 60 is disposed on a side of the plurality of selected first wirings 201 that is close to the display surface side of the array substrate 131, and the at least one second light-shielding bar 60 is disposed on a side of the plurality of selected second wirings 301 that is away from the base substrate 80. In this way, the second light-shielding bar 60 can be manufactured by utilizing the manufacturing process of a light-shielding pattern for blocking the active layer of a thin film transistor in the array substrate 131, and there is no need to provide a separate process for manufacturing the second light-shielding bar 60, which can simplify the manufacturing process of the array substrate 131.

[0092] 8B, the at least one second light-shielding bar 60 is disposed on a side of the plurality of second wirings 301 that is away from or close to the display surface side of the array substrate 131, and the orthogonal projection of each second light-shielding bar 60 on the display surface covers the orthogonal projection of the second converging portion 70 on the display surface. This means that the number of the second light-shielding bars 60 is the same as the number of the second converging portions 70.

[0093] In the array substrate 131 according to the embodiment of the present disclosure, the selected second wirings 301 in the sensitive member region C1 are grouped, 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 convergent portion 70. This corresponds to each selected second wiring 301 of each group of selected second wirings approaching each other in the sensitive member region, so that two adjacent selected second wirings 301 of each group of selected second wirings are closer to each other in the sensitive member region C1, while the distance between two adjacent second convergent portions 70 is greater, and the distance between two adjacent second convergent portions 70 is greater than the distance between two adjacent second wirings 30 in the non-sensitive member region C2.

[0094] In addition, by providing at least one second light-shielding bar 60, the gaps between at least two adjacent selected second wirings 301 in the second converging section 70 are blocked, blocking the transmission of light through these gaps, and preventing the occurrence of the light diffraction phenomenon due to the transmission of light through the gaps between the at least two selected second wirings 301 in the second converging section 70.

[0095] Thus, when a light ray passes through the transparent sensor 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 converging portions 70 is greater than the distance between two adjacent second wires 30 in the non-sensitive member region C2. That is, in the transparent sensor region C1, the arrangement density of the multiple second converging portions 70 (corresponding to the arrangement density of the multiple second light-shielding bars 60) formed after each selected second wire 301 of each group of selected second wires converges is lower than the arrangement density when the multiple second wires 30 do not converge. Therefore, when the light ray passes through the transparent sensor region C1, the diffraction phenomenon is further reduced, the impact of light diffraction on the brightness of light is reduced, and the accuracy of the light ray information sensed by the sensor region 2 is further improved.

[0096] For example, taking the sensor element 2 as a front camera, the diffraction phenomenon is further reduced when the light passes through the transparent sensor element area C1, so that the imaging effect of the front camera is further improved, and the brightness and resolution of the obtained image are better.

[0097] 8A, in the transparent sensitive member region C1 of the array substrate 131, the distance g between two adjacent second converging portions 70 is greater than the distance k between two adjacent second wires 30 in the non-sensitive member region C2. In each second converging portion 70, the distance h between two adjacent selected second wires 301 is less than the distance k between two adjacent second wires 30 in the non-sensitive member region C2.

[0098] In the above embodiment, the distance g between two adjacent second converging portions 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 converging portions 70 is the distance between two selected second wirings 301 located in the two adjacent second converging portions 70, respectively, and closest to each other. Thus, the distance g between two adjacent second converging portions 70 is greater than the distance k between two adjacent second wirings 30 in the non-sensitive member region C2, and correspondingly, 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 passes through the transparent sensitive member region C1.

[0099] Also, in each second converging portion 70, the interval h between two adjacent selected second wirings 301 is smaller than the interval k between two adjacent selected second wirings 30 in the non-sensitive member region C2. As a result, in each second converging portion 70, the two adjacent selected second wirings 301 are closer to each other, and the dimension of the second converging portion 70 in the direction perpendicular to the extending direction of the second converging portion 70 (i.e., the width of the second converging portion 70) is reduced, ensuring that the interval between the two adjacent second converging portions 70 can be increased, thereby further reducing the light diffraction phenomenon and narrowing the width of the second light shielding bar 60 for blocking the gap between at least two adjacent selected second wirings 301 in the second converging portion 70, allowing more light rays to pass through.

[0100] In some embodiments, the number of selected second wirings 301 included in the selected second wirings of each group is not limited, and the selected second wirings of each group may include two selected second wirings 301, as shown in Figures 8A, 8B, and 9A to 9C. The selected second wirings of each group may include two or more selected second wirings 301, and illustratively the number of selected second wirings 301 included in the selected second wirings 301 of each group is three, four, or five.

[0101] In some embodiments, the number of selected second wirings 301 included in the selected second wirings of each group is the same.

[0102] Illustratively, the number of the selected second wirings 301 included in the selected second wirings 301 of each group is two, or the number of the selected second wirings 301 included in the selected second wirings 301 of each group is three, four, or other numbers. The array substrate shown in FIG. 8A shows a case where the selected second wirings 301 of each group include two selected second wirings 301, so that the widths of the multiple second converging parts 70 corresponding to the selected second wirings 301 of the multiple groups can be all equal or approximately equal, and the widths of the second light-shielding bars 60 can be all equal or approximately equal. This makes the degree of reduction of the diffraction of the light beam in each region of the sensitive member region C1 equal or approximately equal, and the light beams passing through each region of the sensitive member region C1 are uniform, thereby further improving the accuracy of the light beam information sensed by the sensitive member 2.

[0103] In some embodiments, the spacing between two adjacent second convergent portions 70 is equal, and the gap between each two adjacent selected second traces of each second convergent portion 70 is equal.

[0104] 8A, the interval between any two adjacent second convergence portions 70 is g. In each second convergence portion 70, when the selected second wiring of each group includes three or more selected second wirings 301, the interval between each two adjacent selected second wirings 301 is equal.

[0105] With this design, the intervals between two adjacent second converging portions 70 are equal, so the intervals between two adjacent second shading bars 60 are also equal or nearly equal; in each second converging portion 70, the intervals between each two adjacent selected second wirings 301 are equal. Thus, the widths of the multiple second converging portions 70 are all equal, and the widths of the second shading bars 60 are equal or nearly equal. As a result, the degree of reduction in the diffraction of the light beam is equal or nearly equal in each region of the sensitive member region C1, so that the light beam passing through each region of the sensitive member region C1 is more uniform, and the accuracy of the light beam information sensed by the sensitive member 2 is further improved.

[0106] In some embodiments of the present disclosure, the effect of reducing the light diffraction phenomenon can be further enhanced by setting the width of one second light-shielding bar 60 and the spacing between two adjacent second light-shielding bars 60 within an appropriate range.

[0107] 9A, 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, and the interval p between two adjacent second light-shielding bars 60 refers to the interval between two adjacent second light-shielding bars 60 in the direction perpendicular to the extension direction of the second light-shielding bars 60. Illustratively, when the extension direction of the second light-shielding bars 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 interval p between two adjacent second light-shielding bars 60 refers to the interval between two adjacent second light-shielding bars 60 in the direction perpendicular to the first direction.

[0108] Furthermore, the width of the second shading bar 60 and the spacing between two adjacent second shading bars 60 can be set by setting the width of the second converging portion 70, the spacing between two adjacent second converging portions 70, and the number of selected first wirings 301 among the selected second wirings of one grape corresponding to each second converging portion 70.

[0109] The lower limit of the interval p between two adjacent second light-shielding bars 60 is set to p1, and the upper limit to p2.

[0110] By setting the interval p between two adjacent second light-shielding bars 60 to the lower limit p1 or more, it is possible to avoid the light diffraction phenomenon that occurs when light passes through the space between the second light-shielding bars 60 because the interval p between two adjacent second light-shielding bars 60 is too small. By setting the interval p between two adjacent second light-shielding bars 60 to the upper limit p2 or less, it is possible to avoid a decrease in the number of second light-shielding bars 60 due to the interval p between two adjacent second light-shielding bars 60 being too large (when the area of ​​the sensitive member region C1 is constant, if the interval p between two adjacent second light-shielding bars 60 is too large, the number of second light-shielding bars 60 will be reduced), and thus a decrease in the number of second converging portions 70 corresponding to the second light-shielding bars 60 will be avoided. In the case of the array substrate 131, when the number of second wirings 30 is constant, the number of selected second wirings 301 passing through the sensitive member area C1 is also constant, and thus the number of selected second wirings 301 in each group corresponding to each second converging portion 70 becomes large. As a result, the selected second wirings 301 of the selected second wirings in each group may affect each other, which may cause fluctuations or inaccuracies in the transmitted signals.

[0111] Also, assume that the lower limit value of the width m of one second light-shielding bar 60 is m1 and the upper limit value is m2. By setting the width m of one second light-shielding bar 60 to be equal to or greater than the lower limit value m1, it is possible to avoid a problem in which 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 converging portion 70 cannot be effectively blocked. By setting the width m of one second light-shielding bar 60 to be equal to or less than the upper limit value m2, it is possible to avoid a problem in which the width m of the second light-shielding bar 60 is too large and therefore the interval p between two adjacent second light-shielding bars 60 becomes too small, which causes light diffraction and reduces the amount of light passing through the sensitive member region C1.

[0112] In view of this, 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 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 spacing p between two adjacent second light-shielding bars 60 may be 1 / 2 or 7.5 / 16.125, etc.

[0113] Exemplarily, when the ratio of the width m of one second light-shielding bar 60 to the interval p between two adjacent second light-shielding bars 60 is greater than 0 and less than or equal to 0.5, the sum (pitch) n of the width m of one second light-shielding bar 60 to the interval p between two adjacent second light-shielding bars 60 is greater than or equal to 94.5 μm and less than or equal to 200 μm. For example, the sum n of the width m of one second light-shielding bar 60 to the interval p between two adjacent second light-shielding bars 60 may be 94.5 μm, 100 μm, 200 μm, etc.

[0114] In addition, the opposing sides of one second shading bar 60 in the first direction may extend beyond the boundary defined by the two outermost selected second wirings 301 of its corresponding second converging portion 70, or may be aligned with the boundary defined by the two outermost selected second wirings 301 of its corresponding second converging portion 70.

[0115] In the above-mentioned embodiments of the present disclosure, the ratio of the width m of one second shading bar 60 to the spacing p between two adjacent second shading bars 60 is greater than 0 and less than 0.5, and the sum of the width m of one second shading bar 60 and the spacing p between two adjacent second shading bars 60 is greater than 94.5 μm and less than 200 μm, so that the light diffraction phenomenon can be further reduced when the light passes through the sensory member area C1, and the light information sensed by the sensory member 2 can be more accurate.

[0116] In some embodiments, the ratio of the width m of one second light-shielding bar 60 to the interval p between two adjacent second light-shielding bars 60 and the ratio of the width d of one first light-shielding bar 40 to the interval e between two adjacent first light-shielding bars 40 may be equal or unequal; the sum n of the width m of one second light-shielding bar 60 to the interval p between two adjacent second light-shielding bars 60 and the sum f of the width d of one first light-shielding bar 40 to the interval e between two adjacent first light-shielding bars 40 may be equal or unequal. Illustratively, when the dimension of the pixel region of the array substrate 131 in the first direction is smaller than the dimension in the second direction, the sum n of the width m of one second light-shielding bar 60 to the interval 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 to the interval e between two adjacent first light-shielding bars 40. For example, in this case, the sum n of the width m of one second shading bar 60 and the spacing p between two second shading bars 60 is 180 μm, and the sum f of the width d of one first shading bar 40 and the spacing e between two adjacent first shading bars 40 is 120 μm.

[0117] In the array substrate 131 according to some embodiments of the present disclosure, there are areas along the extension direction of the second light-shielding bar 60 where thin film transistors are arranged and areas where thin film transistors are not arranged, so when designing the second light-shielding bar 60, the width of the second light-shielding bar 60 is different along the extension direction of the second light-shielding bar 60, for example, the width of the second light-shielding bar 60 is wide at the area where thin film transistors are arranged, and the width of the second light-shielding bar 60 is narrow at the area where thin film transistors are not arranged. Thus, at the area where the width of the second light-shielding bar 60 is narrow, the interval between two adjacent second light-shielding bars 60 is wide, so that more light can pass through the sensitive member area C1 and be sensed by the sensitive member 2.

[0118] In addition, when the width of the second shading bars 60 varies along the extension direction of the second shading bars 60, the distance e between two adjacent second shading bars 60 refers to the distance between the same positions of two adjacent second shading bars 60 in a direction perpendicular to the extension direction of the second shading bars 60.

[0119] In another embodiment, the width of the same second light-shielding bar 60 is the same everywhere along the extension direction of the second light-shielding bar 60. In this way, the manufacturing process of the second light-shielding bar 60 can be simplified and the manufacturing efficiency can be improved. Exemplarily, when the width of the same second light-shielding bar 60 is the same everywhere, the interval between two adjacent second light-shielding bars 60 along the extension direction of the second light-shielding bar 60 may be the same or different. For example, when the width of each second light-shielding bar 60 is the same everywhere, the widths of the multiple second light-shielding bars 60 are all the same. In this way, when manufacturing the second light-shielding bar 60, the process can be simplified and the difficulty of the process can be reduced.

[0120] When the widths of the multiple second light-shielding portions 60 are all the same, the number of the multiple selected second wirings 301 corresponding to each second converging portion 70 can be set to be equal, and the distance between two adjacent selected second wirings 301 among the selected second wirings of each group can be set to be equal, so that the mutual influence between the multiple selected second wirings 301 among the selected second wirings of each group can be made to be the same, thereby making the influence of the multiple groups of selected second wirings 301 in the sensory member area C1 on the transmitted light rays the same, and improving the accuracy of the light ray information collected by the sensory member 2.

[0121] In some embodiments, one second wiring 30 includes one or more second sub-wirings 30a. Exemplarily, as shown in FIG. 8A, one second wiring 30 includes one second sub-wiring 30a. As shown in FIG. 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. 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, so the above-mentioned embodiment is also applicable to each selected second wiring 301.

[0122] 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 a gate line, a control line, a common signal line (Com line), etc. In 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 a data line, an initialization signal line, a first power supply line (Vdd line), a second power supply line (Vss line), etc. 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-mentioned embodiments are similarly applied to each selected second wiring 301.

[0123] In some embodiments, when one second wiring 30 includes multiple second sub-wirings 30a, the types of the second sub-wirings 30a included in the second wiring 30 may be the same or different. For example, one second wiring 30 includes two gate lines. Also, for example, one second wiring 30 includes one gate line and one Vss line. Since the first wiring 201 is a wiring that passes through the sensor region C1 among the multiple second wirings 30 of the array substrate 131, the above-mentioned embodiment is also applicable to each selected second wiring 301.

[0124] In some embodiments, the number of the first sub-wirings 20a included in one first wiring 20 is the same as the number of the second sub-wirings 30a included in one second wiring 30. For example, the number of the first sub-wirings 20a included in one first wiring 20 and the number of the second sub-wirings 30a included in one second wiring 30 are both two. In other embodiments, the number of the first sub-wirings 20a included in one first wiring 20 and the number of the second sub-wirings 30a included in one second wiring 30 are different.

[0125] In some embodiments, the at least one first light-shielding bar 40 of the array substrate 131 is in the same film layer and is made of the same material as the 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 process 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 a light-shielding pattern for blocking the active layer of a thin film transistor in the array substrate 131, so that the manufacturing process of the light-shielding pattern can be reused for the manufacturing of the at least one first light-shielding bar 40 and the at least one second light-shielding bar 60, so that there is no need to provide a separate process for manufacturing the at least one first light-shielding bar 40 and the at least one second light-shielding bar 60, and the manufacturing process of the array substrate can be further simplified.

[0126] In the embodiment of the present 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 play a role of light-shielding. Exemplarily, 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 light-impermeable materials 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 disposed between the at least one first light-shielding bar 40 and the plurality of selected first wirings 201 of the array substrate 131 to avoid 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 disposed between the at least one second light-shielding bar 60 and the plurality of selected second wirings 301 to avoid electrical conduction between them.

[0127] As shown in FIGS. 3A and 3B, some embodiments of the present disclosure provide a display panel 13 including an array substrate 131 according to any of the above-mentioned embodiments.

[0128] The display panel 13 according to the embodiment of the present disclosure may be a liquid crystal display panel (abbreviated as LCD), an organic electroluminescent display panel (abbreviated as OLED), or a quantum dot electroluminescent display panel (abbreviated as Quantum Dot Light-Emitting Display, QLED).

[0129] When 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 .

[0130] When 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 an encapsulation layer that encapsulates the array substrate 131. The array substrate 131 includes a thin film transistor and a light emitting element including an anode, a light emitting layer and a cathode. The encapsulation layer may be a thin film encapsulation layer or a substrate encapsulation layer.

[0131] As shown in FIG. 4A, the display panel 13 according to the embodiment of the present disclosure has a sensitive member region C1 and a non-sensitive member region C2. The non-sensitive member region C2 has a display function, and the sensitive member region C1 is transparent and has a display function. As can be seen from the above embodiments, in the sensitive member region 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 region C1 is designed to converge so that the distance between two adjacent first converging portions 50 (or two adjacent first converging portions 50 and two adjacent second converging portions 70) is increased, thereby reducing the diffraction phenomenon of light passing through the sensitive member region C1 and improving the accuracy of the light information sensed by the sensitive member 2.

[0132] As shown in FIG. 4A, in some embodiments, the display panel 13 may further comprise a non-display area D, which may be, for example, an outer frame.

[0133] 3A and 3B, some embodiments of the present disclosure provide a display device 300 including a display panel 13 and at least one sensitive member 2. Here, the display panel 13 is the display panel 13 provided in the above embodiments.

[0134] The at least one sensitive member 2 is disposed on the non-display side of the display panel 13, and the orthogonal projection of the at least one sensitive member 2 on the display panel 13 is within a sensitive member area C1 of the display panel 13. A sensitive surface of each sensitive member 2 faces the display panel 13. Exemplarily, the at least one sensitive member 2 includes one or more of a front camera, an optical sensor, a 3D sensing module, and the like.

[0135] For example, when the sensor 2 includes a front camera, the photosensitive surface of the front camera faces the display panel 13 and captures an image of a subject located on the front side (i.e., display surface side) of the display device 300 through the sensor region C1 of the display panel 13. For example, when the sensor 2 includes a light sensor, the photosensitive surface of the light sensor faces the display panel 13 and senses light rays from the front side (i.e., display surface side) of the display device 300 through the sensor region C1 of the display panel 13. For example, when the sensor 2 includes a three-dimensional sensing module, the light-emitting surface and the photosensitive surface of the three-dimensional sensing module face the display panel 13 and emit light rays to an object located on the front side (i.e., display surface side) of the display device 300 through the sensor region C1 of the display panel 13, and receive light rays reflected from the object to realize sensing of the three-dimensional spatial structure of the object.

[0136] In the above-mentioned display device 300, when light passes through the sensor area C1 of the display panel 13, it is not diffracted or the degree of diffraction is relatively small, so that the accuracy of the light information sensed by the at least one sensor 2 is improved. For example, when the at least one sensor 2 includes a front camera, the captured image has high brightness and good resolution.

[0137] In the above-mentioned display device 300, the area directly facing the sensor 2 such as a front camera, i.e., the sensor area C1, has a relatively high light transmittance and a relatively small amount of 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 realized, and the photosensitive effect of the sensor 2 is not affected by light diffraction or is only slightly affected by light diffraction.

[0138] The above description is only specific embodiments of the present disclosure, and the scope of protection of the present disclosure is not limited thereto. Any modifications or replacements that a person skilled in the art can easily conceive within the technical scope of the present disclosure shall be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure shall be governed by the scope of rights described in the claims.
