Background Art

[0002] The screen occupation ratio of a display panel refers to the ratio of the area of the display region of the display surface of the display panel to the total area of the display surface of the display panel. Seeking a large screen occupation ratio is one of the development trends in the field of display technologies. A full screen refers to a screen in which the area of the display region of the display surface of the display panel is equal to or approximately equal to the total area of the display surface of the display panel, and its screen occupation ratio is high.

Mode for Carrying Out the Invention

[0022] Hereinafter, with reference 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 herein 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., and the display device can be any device capable of displaying images such as videos (e.g., videos), still images (e.g., still images), characters, pictures, etc.

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

[0025] In some embodiments, the display device includes a sensing member. Taking the case where the terminal to which the display device is applied is a mobile phone as an example, the display device is provided with sensing members such as, for example, a front camera, a light sensor, a 3D sensing module, etc. These sensing members need to sense the light rays from the display surface side of the display device in order to realize the corresponding functions. For example, when the front camera of the mobile phone takes a picture, it is necessary to collect the light of the subject located in the front (i.e., the display surface side) of the mobile phone, thereby realizing imaging.

[0026] In one related art, as shown in FIGS. 1A and 1B, the display panel 11 of the display device 100 has a display area A1 and a non-display area B1. A hole is opened in the display panel 11, and the sensing member 2 (for example, a front camera) is embedded in the opened hole. In this way, the sensing member 2 can sense the light rays from the display surface side of the display panel 11.

[0027] In another related art, as shown in FIGS. 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 disposed on the non-display surface 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. In this way, the light rays from the display surface side of the display panel 12 are transmitted through the transparent area B2 and sensed by the sensing member 2.

[0028] In the above two arrangement methods of the sensing member 2, there are areas that cannot be displayed on the display surface of the display panel, resulting in a decrease in the screen occupancy rate of the display device. The ratio of the area of the display area of the display panel to the total area of the display panel does not reach 100%, and full-screen display cannot be realized.

[0029] To achieve a higher screen occupancy ratio, in some embodiments of the present disclosure, as shown in FIGS. 3A and 3B, the display device 300 includes a display panel 13 and a sensing member 2. The display panel 13 has a sensing member area C1 and a non-sensing member area C2. The non-sensing member area C2 can display an image. The non-sensing member area C2 may surround, for example, the sensing member area C1 that is transparent and capable of image display, or may surround half of the sensing member area C1. The sensing member 2 is disposed on the non-display surface side of the display panel 13, and the sensing member 2 faces the sensing member area C1 of the display panel 13, that is, the orthographic projection of the sensing member 2 on the display surface of the display panel 13 is within the sensing member area C1.

[0030] The sensing surface of the sensing member 2 faces the display panel 13. Since the sensing member area C1 is transparent, the sensing member 2 can sense the light rays from the display surface side of the display panel 13 through the sensing member area C1 and execute corresponding operations. Taking the case where the sensing member 2 is a front camera as an example, the front camera captures the light rays from the subject on the display surface side of the display panel 13 through the sensing member area C1, forms an image, and captures an image of the subject.

[0031] To increase the light transmittance of the sensing member area C1 and enable the sensing member 2 disposed on the non-display surface side of the display panel 13 to sense more light rays from the display surface side of the display panel 1 through the sensing member area C1, in some embodiments, as shown in FIGS. 4A and 4B, the display panel 13 is designed such that the display area of the display panel 13 (including the sensing member area C1 and the non-sensing member area C2) includes, for example, a plurality of pixel dots 10 arranged in an array.

[0032] To more clearly explain the technical solution of the present disclosure, hereinafter, region E is partitioned from the display surface of the display panel 13, and the structure in region E will be described. FIG. 4B is an enlarged structural view 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 that is adjacent to the sensitive member region C1 and located around the sensitive member region C1 within the non-sensitive member region C2. For the structure of the region of the non-sensitive member region C2 located outside region E, reference may be made to the structure of a partial region located within region E of the non-sensitive member region C2.

[0033] Adopt a method of reducing the PPI (Pixels Per Inch, pixel density) of the sensitive member region C1, that is, for the non-sensitive member region C2, by reducing the number of pixel dots 10 in the sensitive member region C1, the occupied space of the pixel dots 10 in the sensitive member region C1 is reduced, leaving space for light rays to pass through, so as to make the sensitive member region C1 have a high light transmittance.

[0034] However, through the research of the inventors of the present disclosure, the following have been discovered.

[0035] As shown in FIG. 4B, in the display region of the display panel 13 (for example, taking region E including a part of the non-sensitive member region C2 and the sensitive member region C1 as an example), a plurality of first wirings 20 extending in the first direction and a plurality of second wirings 30 extending in the second direction are provided. 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. Exemplarily, 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 wiring includes data lines (Data lines), initialization signal lines, first power supply lines (Vdd lines), second power supply lines (Vss lines), etc., and the second wiring includes 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 arrangement of the first wiring 20 is dense, and the interval between two adjacent first wirings 20 is small.

[0036] The arrangement density of the first wiring 20 in the sensitive member region C1 is the same as that in the non-sensitive member region C2. This is because, for each sub-pixel column in which a plurality of pixel dots 10 in the sensitive member region C1 are located, the PPI of the C22 region and the C24 region in the non-sensitive member region C2 among these sub-pixel columns is the same as 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 is the same as 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 sensitive member region C1 in these sub-pixel columns does not decrease due to the decrease in its PPI.

[0037] Thus, in the process where light rays pass through the sensitive member region C1 and propagate between the display surface side of the display panel 13 and the sensitive member 2, a plurality of the first wirings 20 in the sensitive member region C1 are arranged densely, and since the interval between two adjacent first wirings 20 is small, when the light rays pass through the gap between two adjacent first wirings 20 and propagate, a diffraction phenomenon 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 that when light hits an obstacle or a small hole during the propagation process, the light propagates around behind the obstacle from the straight 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 comparable to the light wavelength and is extremely small, the diffraction phenomenon of light is extremely intense, the diffraction phenomenon occurring when the light propagates becomes prominent, and the light rays become dim.

[0038] Taking the case where the sensitive member 2 is a front camera as an example, when the front camera acquires an image through the sensitive member region C1 of the display panel 13, the front camera needs to acquire the light rays of the subject located on the display surface side of the display panel 13 through the sensitive member region C1. However, since the first wiring 20 is arranged densely, light diffraction occurs when the light rays pass through the sensitive member region C1, and the light ray information collected by the front camera becomes inaccurate. As a result, the imaging effect of the front camera deteriorates, and problems such as low image brightness and poor resolution occur.

[0039] In view of the above, as shown in FIGS. 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. The sensitive member region C1 and the non-sensitive member region C2 both have a display function, and the non-sensitive member region C2 may, for example, surround the sensitive member region C1 or surround half of the sensitive member region C1.

[0040] The above 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, the light rays from the display surface side can pass through the sensitive member region C1 and be sensed by the sensitive member 2.

[0041] The above array substrate 131 includes a plurality of first wirings 20 extending in a first direction. The plurality of first wirings 20 are provided at intervals. Among the plurality of first wirings 20, the wiring passing through the sensitive member region C1 is the selected first wiring 201. The plurality of selected first wirings 201 are divided into at least one group, and each group of selected first wirings includes at least two adjacent selected first wirings 201. Each selected first wiring 201 of each group of selected first wirings converges in the sensitive member region C1 to form a first convergence portion 50.

[0042] Exemplarily, as shown in FIG. 5A, the first wirings numbered L 1 ~L 6 are the selected first wirings 201. The plurality of selected first wirings 201 may be divided into three groups. 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 sensitive member region C1 to form one first convergence portion 50. Thus, the three groups of selected first wirings 201 converge in the sensitive member region C1 to form three first convergence portions 50.

[0043] For example, as further shown in FIG. 5A, the selected first wirings 201 numbered L 1 and L 2 converge within the sensing member area C1 to form the first convergence portion 50 as the selected first wirings of one grape, and the selected first wirings 201 numbered L 3 and L 4 converge within the sensing member area C1 to form the first convergence portion 50 as the selected first wirings of one grape, and the selected first wirings 201 numbered L 5 and L 6 converge within the sensing member area C1 to form the first convergence portion 50 as the selected first wirings of one grape. Here, taking the two selected first wirings 201 numbered L 1 and L 2 as an example, the selected first wiring 201 numbered L 2 includes a first portion extending in the first direction and a second portion extending in the second direction. The first portion and the second portion are sequentially and alternately arranged and connected end to end. With this structure, the selected first wiring 201 numbered L 2 approaches the selected first wiring 201 numbered L 1 in the sensing member area C1 to form one first convergence portion 50. The first convergence portion 50 can be understood to include the portion of the selected first wiring 201 numbered L 1 located in the sensing member area C1 and the portion of the selected first wiring 201 numbered L 2 located in the sensing member area C1. Since the structures of the other two first convergence portions 50 are the same as the structure of the first convergence portion 50 described above, the description thereof is omitted here.

[0044] As shown in FIGS. 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 disposed on the side away from or close to the display surface side of the array substrate 131 of the plurality of selected first wirings 201. The orthographic projection of each first light shielding bar 40 on the display surface of the array substrate 131 (that is, when the array substrate 131 is applied to the display panel, it is disposed on the surface for display) covers the orthographic projection of one first convergence portion 50 on the display surface.

[0045] In an embodiment of the present disclosure, if the orthographic projection of each first light-shielding bar 40 on the display surface of the array substrate 131 covers the orthographic projection of the display surface of one first converging portion 50, the position of the at least one first light-shielding bar 50 with respect to the plurality of first arrangements 20 is not limited. Thereby, one first light-shielding bar 40 shields the gap between at least two adjacent selected first wirings 201 of one first converging portion 50, and diffraction caused by light rays passing through the gap between the selected first wirings 201 of the first converging portion 50 can be avoided.

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

[0047] In some embodiments, as shown in FIG. 6B, the at least one first light-shielding bar 40 is disposed on the side closer to the display surface side of the array substrate 131 of the plurality of selected first wirings 201, and the at least one first light-shielding bar 40 is disposed on the side away from the base substrate 80 of the plurality of selected first wirings 201. 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 transistor in the array substrate 131, without the need to separately provide a process for manufacturing the first light-shielding bar 40, and the manufacturing process of the array substrate 131 can be simplified.

[0048] As shown in FIG. 5B, the at least one first light-shielding bar 40 is disposed on the side away from or adjacent to the display surface side of the array substrate 131 of the plurality of selected first wirings 201, and the orthographic projection of each first light-shielding bar 50 on the display surface covers the orthographic 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.

[0049] In the array substrate 131 according to the embodiment of the present disclosure, the selected first wirings 201 in the sensing member region C1 are grouped, and each group of the selected first wirings 201 includes at least two adjacent selected first wirings 201. Each selected first wiring 201 of each group of the selected first wirings converges in the sensing member region C1 to form a first converging portion 50. This corresponds to bringing each selected first wiring 201 of each group of the selected first wirings closer to each other in the sensing member region C1. Thus, two adjacent selected first wirings 201 among each group of the selected first wirings are closer in the sensing member region C1, while the distance between two adjacent first converging portions 50 is farther, and the distance between two adjacent first converging portions 50 is made larger than the distance between two adjacent first wirings 20 in the non-sensing member region C2.

[0050] And by providing at least one first light-shielding bar 40, the gap between at least two adjacent selected first wirings 201 in the first converging portion 50 is blocked, the transmission of light rays from these gaps is blocked, and the occurrence of the light diffraction phenomenon due to the transmission of light rays from the gap between at least two selected first wirings 201 in the first converging portion 50 is prevented.

[0051] In this way, when the light beam 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 converging portions 50 is larger 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 plurality of first converging portions 50 (corresponding to the arrangement density of the plurality of first light-shielding bars 40) formed after each selected first wiring 201 of each group of selected first wirings converges is lower than the arrangement density when the plurality of first wirings 20 do not converge. Therefore, when the light beam passes through the transparent sensitive member region C1, the diffraction phenomenon is reduced, the influence of light diffraction on the light beam luminance is reduced, and the accuracy of the light beam information sensed by the sensitive member 2 is improved.

[0052] Taking the sensitive member 2 as a front camera as an example, since the diffraction phenomenon is reduced when the light beam passes through the transparent sensitive member region C1, the imaging effect of the front camera is improved, and the luminance and resolution of the obtained image are greatly improved.

[0053] In some embodiments, as shown in FIG. 5A, in the transparent sensitive member region C1 of the array substrate 131, the distance a between two adjacent first converging portions 50 is larger than the distance b between two adjacent first wirings in the non-sensitive member region C2. 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 in the non-sensitive member region C2.

[0054] In the above embodiments, 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. The distance a between two adjacent first converging portions 50 is the distance between two selected first wirings 201 that are located within two adjacent first converging portions 50 and are 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, when light rays pass through the transparent sensitive member region C1, the diffraction phenomenon is reduced.

[0055] Also, in each first converging portion 50, since 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, in each first converging portion 50, two adjacent selected first wirings 201 approach each other, and the dimension of the first converging portion 50 in the direction perpendicular to the extending direction of the first converging portion 50 (i.e., the width of the first converging portion 50) becomes smaller, ensuring that the distance between two adjacent first converging portions 50 is increased. Thereby, while reducing the diffraction phenomenon of light, in the first converging portion 50, the width of the first light-shielding bar 40 for blocking the gap between at least two adjacent selected first wirings 201 is narrowed, enabling more light rays to pass through the sensitive member region C1.

[0056] In some embodiments, the number of selected first wirings 201 included in each group of selected first wirings is not limited. Each group of selected first wirings may include two selected first wirings 201, and this situation is shown in FIGS. 5A, 5B, 6A - 6C. Alternatively, each group of selected first wirings may include two or more selected first wirings 201. For example, the number of selected first wirings 201 included in each group of selected first wirings 201 may be three, four, or five.

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

[0058] Exemplarily, the number of the first selected wirings 201 included in the first selected wiring of each group is two, or the number of the first selected wirings 201 included in the first selected wiring of each group is three, four, or other numbers. FIG. 5A shows a case where the first selected wiring of each group includes two first selected wirings 201. Thus, the widths of the plurality of first converging portions 50 corresponding to the first selected wirings of the plurality of groups can be all equal or substantially equal, the widths of the first light shielding bars 40 are equal or substantially equal, and in this way, in each region of the sensor member region C1, the degree of reduction of diffraction with respect to the light beam is equal or substantially equal, the light beam passing through each region of the sensor member region C1 becomes uniform, and thus, the accuracy of the light beam information sensed by the sensor member 2 is further improved.

[0059] In some embodiments, the intervals between two adjacent first converging portions 50 are equal. In each first converging portion 50, the gaps between two adjacent first selected wirings 201 are equal.

[0060] Exemplarily, as shown in FIG. 5A, the intervals between two adjacent first converging portions 50 are all a. In each first converging portion 50, when each first selected wiring includes three or more first selected wirings 201, the intervals between two adjacent first selected wirings 201 are equal.

[0061] With such a design, since the intervals between two adjacent first converging portions 50 are equal, the intervals between two adjacent first light shielding bars 40 are also equal or substantially equal. In each first converging portion 50, since the intervals between two adjacent first selected wirings 201 are equal, the widths of the plurality of first converging portions 50 are all equal, the widths of the plurality of first light shielding bars 40 are equal or substantially equal, and in this way, in each region of the sensor member region C1, the degree of reduction of diffraction of the light beam is equal or substantially equal, the light beam passing through each region of the sensor member region C1 becomes more uniform, and thus, the accuracy of the light beam information sensed by the sensor member 2 is further improved.

[0062] In some embodiments of the present disclosure, 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, the reduction effect of the light diffraction phenomenon can be further enhanced.

[0063] Note that, as shown in FIG. 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 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 in a direction perpendicular to the extending direction of the first light-shielding bar 40. Exemplarily, when 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 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.

[0064] Furthermore, the setting of the width of the first light-shielding bar 40 and the interval between two adjacent first light-shielding bars 40 can be realized by setting the width of the first converging portion 50, the interval between two adjacent first converging portions 50, and the number of the selected first wirings 201 among the selected first wirings corresponding to each converging portion 50.

[0065] 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 its lower limit value e1, it is possible to avoid the diffraction phenomenon of light that may occur when light rays pass through the gaps between multiple 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 situation where the number of first light-shielding bars 40 decreases because the interval e between two adjacent first light-shielding bars 40 is too large (when the area of the sensor 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 decrease), and the number of first converging portions 50 corresponding to the first light-shielding bars 40 will decrease. For the array substrate 131, the number of first wirings 20 is constant, and the number of selected first wirings 201 passing through the sensor member region C1 is also constant. Thus, the number of selected first wirings 201 in each group corresponding to each first converging portion 50 increases, and there is a possibility that the selected first wirings 201 in each group of selected first wirings will affect each other, resulting in fluctuations and inaccuracies in the transmitted signals.

[0066] 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 its lower limit value d1, it is possible to avoid the problem that the gap between two adjacent selected first wirings 201 in the first converging portion 50 cannot be effectively blocked because the width d of the first light-shielding bar 40 is too small. 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 the problems that the diffraction phenomenon of light occurs because the interval e between two adjacent first light-shielding bars 40 is too small or the amount of light rays passing through the sensor member region C1 decreases because the width d of the first light-shielding bar 40 is too large.

[0067] Based on this, in some embodiments, the ratio of the width d of one first light-shielding bar 40 to the interval 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 interval e between two adjacent first light-shielding bars 40 may be 1 / 2 or 7.5 / 16.125, etc.

[0068] 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 less than or equal to 0.5, the sum f of the width d of one first light-shielding bar 40 and the interval 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 interval e between two adjacent first light-shielding bars 40 may be 94.5 μm, 100 μm, or 200 μm, etc.

[0069] In addition, both sides of one first light-shielding bar 40 facing each other 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.

[0070] In the above-described embodiments of the present disclosure, by setting 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 to be greater than 0 and less than or equal to 0.5, and setting the sum of the width d of one first light-shielding bar 40 and the interval e between two adjacent first light-shielding bars 40 to be 94.5 μm or more and 200 μm or less, when the light passes through the sensitive member region C1, the diffraction phenomenon of light can be further reduced, and the light information sensed by the sensitive member 2 can be made more accurate.

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

[0072] In the array substrate 131 according to some embodiments of the present disclosure, along the extending direction of the first light-shielding bar 40, there are locations where thin-film transistors are arranged and locations where thin-film transistors are not arranged. Therefore, when designing the first light-shielding bar 40, in one embodiment, along the extending direction of the first light-shielding bar 40, the width of the first light-shielding bar 40 is different. For example, at the location where the thin-film transistor is arranged, the width of the first light-shielding bar 40 is wide, and at the location where the thin-film transistor is not arranged, the width of the first light-shielding bar 40 is narrow. In this way, at the position where the width of the first light-shielding bar 40 is narrow, the distance between two adjacent first light-shielding bars 40 becomes wider, so that more light rays can pass through the sensing member region C1 and be sensed by the sensing member 2.

[0073] Note that when the width of the first light-shielding bar 40 is different along the extending direction of the first light-shielding bar 40, the distance e between two adjacent first light-shielding bars 40 refers to the distance between the same positions of two adjacent first light-shielding bars 40 in the direction perpendicular to the extending direction of the first light-shielding bar 40.

[0074] In other embodiments, along the extending direction of the first light-shielding bar 40, the width of the same first light-shielding bar 40 is the same everywhere. Thus, 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 gaps 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 the plurality of first light-shielding bars 40 are all the same. Thereby, when manufacturing the first light-shielding bar 40, the process is simplified, and the difficulty level of the process can be reduced.

[0075] When the widths of the plurality of first light-shielding portions 40 are all the same, by equally setting the number of the plurality of selected first wirings 201 corresponding to each first converging portion 50 and equally setting the intervals between two adjacent selected first wirings 201 among the selected first wirings in each group, the degree of mutual influence among the plurality of selected first wirings 201 in each group of selected first wirings can be made the same. Thereby, the influence on the transmitted light rays of the plurality of groups of selected first wirings 201 in the sensitive member region C1 can be made the same, and the accuracy of the light ray information collected by the sensitive member 2 can be improved.

[0076] 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 a plurality of first sub-wirings 20a, the two adjacent first sub-wirings 20a are spaced apart from each other. Since the selected first wiring 201 is the wiring passing through the sensitive member region C1 among the plurality of first wirings 20 of the array substrate 131, the above-described embodiments are similarly applicable 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 a data line, an initialization signal line, a first power supply line (Vdd line), a second power supply line (Vss line), and the like. 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 a gate line, a control line, a common voltage signal line, and the like. Since the selected first wiring 201 is a wiring that passes through the sensitive member region C1 of the plurality of first wirings 20 of the array substrate 131, the above-described embodiments are similarly applicable to each selected first wiring 201.

[0078] In some embodiments, when one first wiring 20 includes a plurality of 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. Since the selected first wiring 201 is a wiring that passes through the sensitive member region C1 among the plurality of first wirings of the array substrate, the above-described embodiments are similarly applicable to each selected first wiring 201.

[0079] In some embodiments, one column of sub-pixels is coupled to one first sub-wiring 20a. In this case, when one pixel dot 10 includes at least one sub-pixel, one column of pixel dots corresponds to at least one first sub-wiring. For example, as shown in FIG. 5A, when one pixel dot 10 includes one sub-pixel, one column of pixel dots corresponds to one first sub-wiring 20a. Further, for example, as shown in FIG. 7, when one pixel dot 10 includes two sub-pixels, one column of pixel dots corresponds to two first sub-wirings 20a. Further, for example, when one pixel dot 10 includes three sub-pixels, one column of pixel dots corresponds to three first sub-wirings 20a. Since the selected first wiring 201 is a wiring that passes through the sensitive member region C1 among the plurality of first wirings 10 of the array substrate, the above-described embodiments are similarly applicable to each selected first wiring 201.

[0080] Exemplarily, when one first wiring 20 is connected to a column of sub-pixels, the number of sub-pixels included in one pixel dot 10 is related to the number of data lines included in the first wiring 20 connected to the pixel dot 10. For example, if one pixel dot 10 includes one sub-pixel, the first wiring 20 connected to the pixel dot 10 includes one data line; if one pixel dot 10 includes two sub-pixels, the first wiring 20 connected to the pixel dot 10 includes two data lines; if one pixel dot 10 includes three sub-pixels, the first wiring 20 connected to the pixel dot 10 includes three data lines.

[0081] In view of the above, as shown in FIG. 7, when a column of pixel dots corresponds to at least two first sub-wirings 20a, in each column of pixel dots passing through the sensor member region C1, each first sub-wiring 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 sensor member region C1 more regular and further reducing the diffraction degree of the light rays passing through the region.

[0082] As further shown in FIG. 4B, the array substrate further includes a plurality of second wirings 30 along a second direction intersecting the first direction. In the non-sensor 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. Particularly in a display device with a high PPI, the arrangement density of the second wirings 30 is higher. Thus, in the process of light propagating between the display surface side of the display panel 13 and the sensor member 2 after passing through the sensor member region C1, since the interval between two adjacent second wirings 30 is small, a diffraction phenomenon may occur when the light rays pass through the gap between two adjacent first wirings 30, which may affect the accuracy of the light ray information sensed by the sensor member 2.

[0083] In view of this, in some embodiments, as shown in FIGS. 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 the 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, the example is that the first direction and the second direction are perpendicular to each other.

[0084] The plurality of second wirings 30 are arranged at intervals. Among the plurality of second wirings 30, the wiring passing through the sensing member region C1 is the selected second wiring 301. The plurality of selected second wirings 301 are divided into at least one group. Each group of selected second wirings includes at least two adjacent selected second wirings 301. Each selected second wiring 301 of each group of selected second wirings converges in the sensing member region C1 to form a second convergence portion 70.

[0085] Exemplarily, as shown in FIG. 8A, the second wirings numbered T 1 ~T 4 are the selected second wirings 301. The plurality of selected second wirings 301 may be divided into two groups. Each group of selected second wirings includes two adjacent selected second wirings 301. 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 portion 70. Thus, the two groups of selected second wirings 301 converge in the sensing member region C1 to form two second convergence portions 70.

[0086] For example, as shown in FIG. 8A, the selected second wirings numbered T 1 and T 2 are converged as one group of selected second wirings to form one second convergence portion 70 in the sensing member region C1. The selected second wirings numbered T 3 and T 4 are converged as one group of selected second wirings to form one second convergence portion 70 in the sensing member region C1. Here, the selected second wirings numbered T 1 and T2 Taking two selected second wirings 301 with numbers as an example, the selected second wiring 301 with number T 2 The selected second wiring 301 includes a first portion extending in the second direction and a second portion extending in the first direction. The first portion and the second portion are sequentially arranged alternately and are connected end to end. With such a structure, the selected second wiring 301 with number T 2 The selected second wiring 301 approaches the selected second wiring 301 with number T in the sensing member region C1 and forms a second converging portion 70. The second converging portion 70 includes a portion of the selected second wiring 301 with number T located in the sensing member area C1 of the selected second wiring 301 with number T 1 The selected second wiring 301 approaches the selected second wiring 301 with number T in the sensing member region C1 and forms a second converging portion 70. The second converging portion 70 includes a portion of the selected second wiring 301 with number T located in the sensing member area C1 of the selected second wiring 301 with number T 1 The selected second wiring 301 approaches the selected second wiring 301 with number T in the sensing member region C1 and forms a second converging portion 70. The second converging portion 70 includes a portion of the selected second wiring 301 with number T located in the sensing member area C1 of the selected second wiring 301 with number T 2 The selected second wiring 301 approaches the selected second wiring 301 with number T in the sensing member region C1 and forms a second converging portion 70. The second converging portion 70 includes a portion of the selected second wiring 301 with number T located in the sensing member area C1 of the selected second wiring 301 with number T. It can be understood that the structure of the other second converging portion 70 is the same as that of the second converging portion 70 described above, so the description thereof is omitted here.

[0087] As shown in FIGS. 9A to 9C, at least one second light-shielding bar 60 is disposed on the side away from or close to the display surface side of the array substrate 131 of the plurality of selected second wirings 301. The orthographic projection on the display surface of each second light-shielding bar 60 (that is, the surface disposed on the surface for display when the array substrate 131 is applied to the display panel) covers the orthographic projection on the display surface of the second converging portion 70.

[0088] In the embodiment of the present disclosure, if 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 converging portion 70, the position of the at least one second light-shielding bar 60 with respect to the plurality of second arrangements 30 is not limited. Thereby, one second light-shielding bar 60 can shield the gap between at least two adjacent selected second wirings 301 of one second converging portion 70, and diffraction caused by light passing through the gap between the selected second wirings 301 of the second converging portion 70 can be avoided.

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

[0090] In some embodiments, as shown in FIG. 9B, the at least one second light-shielding bar 60 is disposed on the side closer to the display surface side of the array substrate 131 of the plurality of selected first wirings 201, and the at least one second light-shielding bar 60 is disposed on the side away from the base substrate 80 of the plurality of selected second wirings 301. 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 transistor in the array substrate 131, eliminating the need to separately provide a process for manufacturing the second light-shielding bar 60 and simplifying the manufacturing process of the array substrate 131.

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

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

[0093] Further, by providing at least one second light-shielding bar 60, the gap between at least two adjacent selected second wirings 301 in the second convergence portion 70 is blocked, the transmission of light rays from these gaps is blocked, and the occurrence of the light diffraction phenomenon due to the transmission of light rays from the gap between at least two selected second wirings 301 in the second convergence portion 70 is prevented.

[0094] Thus, when the light rays pass through the transparent sensing member region C1 of the array substrate 131, they pass through the space between two adjacent second light-shielding bars 60, and the distance between two adjacent second convergence portions 70 is larger than the distance between two adjacent second wirings 30 in the non-sensing member region C2. That is, in the transparent sensing member region C1, the arrangement density of a plurality of second convergence portions 70 (corresponding to the arrangement density of a plurality of second light-shielding bars 60) formed after each selected second wiring 301 in each group of selected second wirings converges is lower than the arrangement density when a plurality of second wirings 30 do not converge. Therefore, when the light rays pass through the transparent sensing member region C1, the diffraction phenomenon is further reduced, the influence of light diffraction on the light luminance is reduced, and the accuracy of the light ray information sensed by the sensing member 2 is further improved.

[0095] Taking the case where the sensing member 2 is a front camera as an example, when light passes through the transparent sensing member region C1, the diffraction phenomenon is further reduced, so that the imaging effect of the front camera is further improved, and the brightness and resolution of the obtained image are better.

[0096] In some embodiments, as shown in FIG. 8A, in the transparent sensing 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 wirings 30 in the non-sensing member region C2. In each second converging portion 70, the distance h between two adjacent selected second wirings 301 is smaller than the distance k between two adjacent second wirings 30 in the non-sensing member region C2.

[0097] 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-sensing member region C2. Here, the distance g between two adjacent second converging portions 70 is the distance between two closest selected second wirings 301 respectively located at two adjacent second converging portions 70. Thereby, the distance g between two adjacent second converging portions 70 becomes greater than the distance k between two adjacent second wirings 30 in the non-sensing member region C2. Correspondingly, the distance between two adjacent second light-shielding bars 60 becomes greater than the distance b between two adjacent second wirings 30 in the non-sensing member region C1. Thereby, when light passes through the transparent sensing member region C1, the diffraction phenomenon is reduced.

[0098] 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, two adjacent selected second wirings 301 approach 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) becomes smaller, ensuring that the interval between two adjacent second converging portions 70 can be increased. Thereby, the diffraction phenomenon of light is further reduced. Also, in the second converging portion 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 FIGS. 8A, 8B, 9A to 9C. Each group of selected second wirings may include two or more selected second wirings 301. Exemplarily, the number of selected second wirings 301 included in each group of selected second wirings 301 is three, four, or five.

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

[0101] Exemplarily, the number of the second selection wirings 301 included in the second selection wiring 301 of each group is two, or the number of the second selection wirings 301 included in the second selection wiring 301 of each group is three, four, or other numbers. The array substrate shown in FIG. 8A shows the case where the second selection wiring 301 of each group includes two second selection wirings 301. Thereby, the widths of the plurality of second converging portions 70 corresponding to the second selection wirings 301 of the plurality of groups can all be equal or substantially equal, and the width of the second light shielding bar 60 can be equal or substantially equal. Thereby, in each region of the sensor member region C1, the degree of reduction of the diffraction of the light beam is equal or substantially equal, and the light beam passing through each region of the sensor member region C1 becomes uniform, whereby the accuracy of the light beam information sensed by the sensor member 2 is further improved.

[0102] In some embodiments, the distance between two adjacent second converging portions 70 is equal, and the gap between two adjacent second selection wirings of each second converging portion 70 is equal.

[0103] Exemplarily, as shown in FIG. 8A, the distance between two adjacent second converging portions 70 is all g. In each second converging portion 70, when the second selection wiring of each group includes three or more second selection wirings 301, the distance between two adjacent second selection wirings 301 is equal.

[0104] With such a design, since the distance between two adjacent second converging portions 70 is equal, the distance between two adjacent second light shielding bars 60 is also equal or substantially equal, and in each second converging portion 70, the distance between two adjacent second selection wirings 301 is equal. Thus, the widths of the plurality of second converging portions 70 are all equal, and the width of the second light shielding bar 60 is equal or substantially equal. As a result, in each region of the sensor member region C1, the degree of reduction of the diffraction of the light beam is equal or substantially equal, the light beam passing through each region of the sensor member region C1 becomes more uniform, and the accuracy of the light beam information sensed by the sensor member 2 is further improved.

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

[0106] Note that, as shown in FIG. 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 extending 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 a direction perpendicular to the extending direction of the second light-shielding bar 60. Exemplarily, when the extending 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 interval p between two adjacent second light-shielding bars 60 refers to the interval between two adjacent second light-shielding bars 60 in a direction perpendicular to the first direction.

[0107] Furthermore, the setting of the width of the second light-shielding bar 60 and the interval between two adjacent second light-shielding bars 60 can be realized by setting the width of the second converging portion 70, the interval between two adjacent second converging portions 70, and the number of the selected first wirings 301 among the selected second wirings corresponding to each second converging portion 70 for one grape.

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

[0109] By setting the distance p between two adjacent second light-shielding bars 60 to be not less than its lower limit value p1, it is possible to avoid the light diffraction phenomenon that occurs when light passes through the space between a plurality of second light-shielding bars 60 because the distance p between two adjacent second light-shielding bars 60 is too small. By setting the distance p between two adjacent second light-shielding bars 60 to be not more than its upper limit value p2, it is possible to avoid the situation where the number of second light-shielding bars 60 decreases because the distance p between two adjacent second light-shielding bars 60 is too large (when the area of the sensing member region C1 is constant, if the distance p between two adjacent second light-shielding bars 60 is too large, the number of second light-shielding bars 60 will decrease), and it is possible to avoid the reduction in the number of second converging portions 70 corresponding to the second light-shielding bars 60. 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 sensing member region C1 is also constant. Thus, the number of selected second wirings 301 in each group corresponding to each second converging portion 70 increases, and therefore there is a possibility that the selected second wirings 301 in each group of selected second wirings affect each other, resulting in fluctuations and inaccuracies in the transmitted signals.

[0110] 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 not less than its lower limit value m1, it is possible to avoid the problem that the gap between two adjacent selected second wirings 301 of the second converging portion 70 cannot be effectively blocked because the width m of the second light-shielding bar 60 is too small. By setting the width m of one second light-shielding bar 60 to be not more than its upper limit value m2, it is possible to avoid the problem that the distance p between two adjacent second light-shielding bars 60 becomes too small, resulting in the occurrence of the light diffraction phenomenon and a decrease in the amount of light passing through the sensing member region C1 because the width m of the second light-shielding bar 60 is too large.

[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 not more than 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] 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 not more than 0.5, the sum (pitch) n of the width m of one second light-shielding bar 60 and the interval 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 interval p between two adjacent second light-shielding bars 60 may be 94.5 μm, 100 μm, 200 μm, etc.

[0113] Note that both opposite sides of one second light-shielding bar 60 in the first direction may cross the boundary defined by the outermost two selected second wirings 301 of its corresponding second converging portion 70, or may be aligned with the boundary defined by the outermost two selected second wirings 301 of its corresponding second converging portion 70.

[0114] In the above-described embodiments of the present disclosure, by setting 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 to be greater than 0 and not more than 0.5, and setting the sum of the width m of one second light-shielding bar 60 and the interval p between two adjacent second light-shielding bars 60 to be 94.5 μm or more and 200 μm or less, when the light beam passes through the sensitive member region C1, the diffraction phenomenon of light can be further reduced, and the light beam information sensed by the sensitive member 2 can be made more accurate.

[0115] 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 may not be equal. The sum n of the width m of one second light-shielding bar 60 and 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 and the interval e between two adjacent first light-shielding bars 40 may be equal or may not be equal. Exemplarily, 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 and the interval p between two adjacent second light-shielding bars 60 is larger than the sum f of the width d of one first light-shielding bar 40 and 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 light-shielding bar 60 and the interval 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 interval e between two adjacent first light-shielding bars 40 is 120 μm.

[0116] In the array substrate 131 according to some embodiments of the present disclosure, along the extending direction of the second light-shielding bar 60, there are locations where thin-film transistors are arranged and locations where thin-film transistors are not arranged. Therefore, when designing the second light-shielding bar 60, along the extending direction of the second light-shielding bar 60, the width of the second light-shielding bar 60 is different. For example, at the location where the thin-film transistor is arranged, the width of the second light-shielding bar 60 is wide, and at the location where the thin-film transistor is not arranged, the width of the second light-shielding bar 60 is narrow. In this way, at the position where the width of the second light-shielding bar 60 is narrow, the interval between two adjacent second light-shielding bars 60 becomes wide, so that more light rays can pass through the photosensitive member region C1 and be sensed by the photosensitive member 2.

[0117] It should be noted that when the width of the second light-shielding bar 60 is different 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 the same positions of two adjacent second light-shielding bars 60 in the direction perpendicular to the extending direction of the second light-shielding bar 60.

[0118] In other embodiments, along the extending direction of the second light-shielding bar 60, the width of the same second light-shielding bar 60 is the same everywhere. 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 intervals 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, when the width of each second light-shielding bar 60 is the same everywhere, the widths of the plurality of second light-shielding bars 60 are all the same. In this way, when manufacturing the second light-shielding bar 60, the process is simplified and the difficulty of the process can be reduced.

[0119] When the widths of the plurality of second light-shielding portions 60 are all the same, the number of selected second wirings 301 corresponding to each second converging portion 70 is set to be equal, and the intervals between two adjacent selected second wirings 301 among the selected second wirings in each group are set to be equal, whereby the mutual influence among the plurality of selected second wirings 301 in each group of selected second wirings can be made the same, and thus the influence on the transmitted light rays of the plurality of groups of selected second wirings 301 in the sensitive member region C1 can be made the same, and the accuracy of the light ray information collected by the sensitive member 2 can be improved.

[0120] 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 a plurality of second sub-wirings 30a, the two adjacent second sub-wirings 30a are spaced apart from each other. Since the second wiring 301 is the wiring passing through the sensitive member region C1 among the plurality of second wirings 30 of the array substrate 131, the above-described embodiments are similarly applicable 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 a gate line, a control line, a common signal line (Com line), and the like. 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 a data line, an initialization signal line, a first power supply line (Vdd line), a second power supply line (Vss line), and the like. Since the second wiring 301 is a wiring passing through the sensing member region C1 among the plurality of second wirings 30 of the array substrate 131, the above-described embodiments are similarly applicable to each selected second wiring 301.

[0122] In some embodiments, when one second wiring 30 includes a plurality of 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 passing through the sensing member region C1 among the plurality of second wirings 30 of the array substrate 131, the above-described embodiments are similarly applicable to each selected second wiring 301.

[0123] In some embodiments, the number of the plurality of first sub-wirings 20a included in one first wiring 20 is the same as the number of the plurality of second sub-wirings 30a included in one second wiring 30. For example, the number of the plurality of first sub-wirings 20a included in one first wiring 20 and the number of the plurality of second sub-wirings 30a included in one second wiring 30 are both two. In some other embodiments, the number of the plurality of first sub-wirings 20a included in one first wiring 20 is different from the number of the plurality of second sub-wirings 30a included in one second wiring 30.

[0124] In some embodiments, at least one first light-shielding bar 40 of the array substrate 131 is in the same film layer as at least one second light-shielding bar 60 and is made of the same material. 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. Further, 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 transistor in 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 to separately provide a process for manufacturing the at least one first light-shielding bar 40 and the at least one second light-shielding bar 60 and further simplifying the manufacturing process of the array substrate.

[0125] In embodiments of the present disclosure, the materials of the at least one first light-shielding bar 40 and the at least one second light-shielding bar 60 are not limited as long as they can serve the function of light shielding. Exemplarily, the materials of the at least one first light-shielding bar 40 and the at least one second light-shielding layer 60 are both one of light-non-transmissive materials such as black ink, black resin, or metal. When 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 a plurality of selected first wirings 201 of the array substrate 131 to avoid electrical conduction between the two. When 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 the two.

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

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

[0128] 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.

[0129] When the display panel 13 is an organic light-emitting display panel or a quantum dot light-emitting display panel, the display panel 13 includes an array substrate 131 and a sealing layer for sealing 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 sealing layer may be a thin film sealing layer or a substrate sealing layer.

[0130] As shown in FIG. 4A, the display panel 13 according to an 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 convergently designed so that the interval between two adjacent first converging portions 50 (or two adjacent first converging portions 50 and two adjacent second converging portions 70) increases. Thereby, the diffraction phenomenon of the light transmitted through the sensitive member region C1 is reduced, and the accuracy of the light ray information sensed by the sensitive member 2 is improved.

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

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

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

[0134] For example, when the sensing member 2 includes a front camera, the photosensitive surface of the front camera faces the display panel 13, and images of subjects located on the front side (i.e., the display surface side) of the display device 300 are captured through the sensing member area C1 of the display panel 13. For example, when the sensing member 2 includes a light sensor, the photosensitive surface of the light sensor faces the display panel 13, and light rays from the front (i.e., the display surface side) of the display device 300 are sensed through the sensing member area C1 of the display panel 13. For example, when the sensing member 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, light rays are emitted to an object located on the front (i.e., the display surface side) of the display device 300 through the sensing member area C1 of the display panel 13, and the light rays reflected from the object are received to realize the sensing of the three-dimensional space structure of the object.

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

[0136] In the above display device 300, for example, in the region facing the sensing member 2 such as a front camera, that is, the sensing member region C1 has a relatively high light transmittance and relatively small light diffraction. Therefore, when this display device 300 is applied to terminals such as mobile phones and tablets, the screen occupancy rate of the terminal can be greatly improved, full-screen display can be realized, and the photosensitive effect of the sensing member 2 is not affected by light diffraction or the influence of light diffraction is slight.

[0137] What has been described above is only specific embodiments of the present disclosure, and the protection scope of the present disclosure is not limited thereto. Any changes and substitutions that can be easily conceived by those skilled in the art within the technical scope of the present disclosure shall be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be based on the scope of rights described in the above patent claims.

[0138] This application claims priority based on a Chinese patent application with an application number of 201811185860.1 and an application title of "Display Panel and Display Device", which was filed with the Chinese Patent Office on October 11, 2018, and all of its content is incorporated herein by reference.
