[0084] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0085] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0088] Organic Light-Emitting Diode (OLED) display devices have been listed as a display technology with great development prospects due to their advantages such as thinness, lightness, wide viewing angle, active light emission, continuously adjustable light color, low cost, fast response speed, low energy consumption, low driving voltage, wide operating temperature range, simple production process, high light emission efficiency and flexible display.

[0089] Photosensitive elements can convert light of different intensities into photocurrents of different sizes. Therefore, photosensitive elements are widely used in fields such as obtaining light intensity parameters and obtaining patterns through different light intensities, such as fingerprint recognition in display panels. In fingerprint recognition applications, when a finger is placed above the photosensitive element in the fingerprint recognition element, the light emitted by the light source is incident on the valleys and ridges of the finger, and after reflection, it is incident on the photosensitive element. Since the light intensities reflected from the valleys and ridges of the finger to the photosensitive element are different, the photocurrents generated by the photosensitive element are different, and then the processing circuit can obtain the fingerprint pattern of the finger based on different photoelectric signals.

[0090] However, the photosensitive elements in the related prior art are easily interfered by other stray light, which affects the efficiency and progress of photosensitivity recognition.

[0091] For a better understanding, some explanations are given before going into detail:

[0092] Sub-pixels: Sub-pixels are composed of small grids that display images. These small grids have a clear position and assigned color values, and the clear position is determined by the pixel arrangement, and the assigned color value is determined by the pixel circuit. The color and position of these small grids determine the appearance of the displayed image.

[0093] Resolution: Display resolution refers to the precision of the displayed image, specifically, how many sub-pixels the display can display. For example, common resolutions are HD: 720*1280, FHD: 1080*1920, QHD: 1440*2560, and UHD (2K\4K): 2160*3840. Taking FHD as an example, it means that there are 1080 R sub-pixels, 1080 G sub-pixels, and 1080 B sub-pixels in one direction, and 1920 R sub-pixels, 1920 G sub-pixels, and 1920 B sub-pixels in the other direction.

[0094] PPI (Pixels Per Inch): Also known as pixel density, it indicates the number of pixels in one inch. For example, FHD resolution and 5-inch size have 441 PPI. Therefore, it can be considered that under the premise that the size of the display is certain, the higher the resolution, the higher the PPI.

[0095] Aperture ratio: Aperture ratio refers to the ratio of the effective light-transmitting area to the total area of ​​a pixel, that is, the ratio between the area of ​​the part through which light passes after removing the wiring and transistor parts of each sub-pixel and the overall area of ​​each sub-pixel. The higher the aperture ratio, the more efficient the light passing through.

[0096] It should be pointed out that those skilled in the art should know that based on the pixel arrangement structure of the present application, each sub-pixel should be distributed as evenly as possible.

[0097] Figure 1 FIG. 1 shows a cross-sectional view of the overall structure of a display panel 100 provided in one embodiment of the present application. Figure 2 A schematic diagram of the arrangement of the repeating units 110 in the display panel 100 provided in one embodiment of the present application is shown.

[0098] In order to at least partially solve the technical problems in the related art, please refer to Figure 1 to Figure 2 The embodiment of the present application provides a display panel 100, which includes a substrate 120 and a plurality of repeating units 110. The repeating unit 110 is arranged on the substrate 120. The repeating unit 110 includes a first sub-pixel 111, a second sub-pixel 112, a third sub-pixel 113 and a photosensitive unit 114. In any repeating unit 110, the first sub-pixel 111 and the photosensitive unit 114 are located in the same row, the second sub-pixel 112 and the third sub-pixel 113 are located in another adjacent row, and at least a portion of the photosensitive unit 114 is arranged adjacent to the third sub-pixel 113; wherein the photosensitive unit 114 is configured to be able to receive light emitted by the third sub-pixel 113 and reflected by an object above the display panel 100.

[0099] The display panel 100 includes a display area and a non-display area, and the display area displays an image by arranging a plurality of sub-pixels located in the display area. Specifically, the display area may be a rectangle, and the non-display area is arranged around the display area. Of course, the shape and arrangement of the display area and the non-display area include but are not limited to the above examples. For example, when the display panel 100 is used for a wearable device worn on a user, the display area may have a circular shape like a watch; when the display panel 100 is used for display on a vehicle, the display area and the non-display area may adopt, for example, a circular, polygonal or other shape. The display area is provided with a plurality of sub-pixels emitting light of different colors, and a sub-pixel is characterized as the smallest unit for emitting light.

[0100] The substrate 120 is a structure used to support and carry other film layers in the display panel 100. For example, the substrate 120 can be made of materials such as glass and polyimide (PI). A driving circuit can be set in the substrate 120 to drive the sub-pixels to emit light. The display panel 100 provided in the embodiment of the present application can be an organic light-emitting display panel 100. The sub-pixels at least include an anode and a cathode, and a light-emitting area 116 located between the anode and the cathode. The driving circuit applies a voltage between the anode and the cathode to stimulate carrier migration and act on the light-emitting area 116 to emit light. The light-emitting area 116 of the sub-pixel may include a multi-layer structure. For example, each light-emitting area 116 includes a stacked hole injection part, a hole transport part, a light-emitting part, an electron transport part, an electron injection part, etc. (not shown in the figure).

[0101] The arrangement of the multiple repeating units 110 on the substrate 120 is not limited here. In some embodiments, the multiple repeating units 110 can be arranged in an array, that is, the centers of the multiple repeating units 110 are staggered along at least two directions to form an array.

[0102] Each repeating unit 110 includes at least one first sub-pixel 111, at least one second sub-pixel 112, at least one third sub-pixel 113, and at least one photosensitive unit 114, wherein the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 may be one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel, respectively. Of course, in some other embodiments, the first sub-pixel 111, the second sub-pixel 112, and the third sub-pixel 113 may also be sub-pixels that emit light of other colors besides red, green, and blue, such as white or yellow, which is not limited here. In any repeating unit 110, the first sub-pixel 111 and the photosensitive unit 114 are located in the same row, the second sub-pixel 112 and the third sub-pixel 113 are located in another adjacent row, and at least a portion of the photosensitive unit 114 is arranged adjacent to the third sub-pixel 113. That is, in the repeating unit 110, the first sub-pixel 111 and the photosensitive unit 114 are alternately arranged in different rows with the second sub-pixel 112 and the third sub-pixel 113, so that at least a portion of the photosensitive unit 114 can be conveniently arranged adjacent to the third sub-pixel 113, that is, at least a portion of the structure of the photosensitive unit 114 and the third sub-pixel 113 is not blocked by other sub-pixels in the repeating unit 110.

[0103] In this embodiment, by setting the arrangement position between the third sub-pixel 113 and the photosensitive unit 114 in the display panel 100, at least a portion of the photosensitive unit 114 is arranged adjacent to the third sub-pixel 113, the third sub-pixel 113 can be used as a signal light source of the photosensitive unit 114, so that the photosensitive unit 114 can receive the light emitted by the third sub-pixel 113 and reflected by the object above the display panel 100, thereby realizing its sensing, recognition and other functions.

[0104] Therefore, the display panel 100 of the embodiment of the present application improves the aperture ratio of the display panel 100 by staggering the first sub-pixel 111 and the photosensitive unit 114 in any repeating unit 110 with the second sub-pixel 112 and the third sub-pixel 113 in different rows, and arranges at least a portion of the photosensitive unit 114 adjacent to the third sub-pixel 113, so that the photosensitive unit 114 can easily receive the light emitted by the third pixel and reflected by the object above the display panel 100, thereby reducing the stray light interference to the photosensitive unit 114 and improving the performance of the photosensitive unit 114.

[0105] Figure 3A schematic structural diagram of a repeating unit 110 in a display panel 100 provided in an embodiment of the present application is shown.

[0106] The plurality of repeating units 110 may be arranged in an array. For example, the plurality of repeating units 110 may be arranged in an array by staggering along a first direction x and a second direction y that intersect each other. Figure 2 Also see Figure 3 , in this case, a plurality of repeating units 110 are arranged in rows along a first direction x, and in columns along a second direction y intersecting the first direction x. The rows and columns in which the repeating units 110 are arranged are relative, and the repeating units 110 arranged in rows may be repeating units 110 arranged in columns in other embodiments. The angle between the first direction x and the second direction y is not limited, and in some embodiments, in particular, the first direction x may be perpendicular to the second direction y.

[0107] And, in some embodiments, as Figure 3 As shown, each repeating unit 110 includes a first sub-pixel 111, a second sub-pixel 112, a third sub-pixel 113 and a photosensitive unit 114, that is, the number ratio of the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113 and the photosensitive unit 114 is 1:1:1:1. In this embodiment, the first sub-pixel 111 and the photosensitive unit 114 are arranged in the same row along the first direction x, and the second sub-pixel 112 and the third sub-pixel 113 are arranged in another adjacent row along the first direction x, and the first sub-pixel 111 is at least partially located between the second sub-pixel 112 and the third sub-pixel 113, and the third sub-pixel 113 is at least partially located between the first sub-pixel 111 and the photosensitive unit 114. Figure 3 As shown, exemplarily, the first sub-pixel 111 and the photosensitive unit 114 are interlaced with the second sub-pixel 112 and the third sub-pixel 113 in two adjacent rows to achieve the above arrangement.

Specifically, the light-emitting area of ​​the first sub-pixel 111, the light-emitting area of ​​the second sub-pixel 112 and the light-emitting area of ​​the third sub-pixel 113 all have a first symmetry axis L1 parallel to the first direction x, and the photosensitive unit 114 has a third symmetry axis L3 parallel to the first direction x. In any repeating unit 110, the first symmetry axis L1 of the first sub-pixel 111 is collinear with the third symmetry axis L3 of the photosensitive unit 114. In any repeating unit 110, the first symmetry axis L1 of the second sub-pixel 112 is collinear with the first symmetry axis L1 of the third sub-pixel 113. In this way, by setting the arrangement of multiple repeating units 110 in the display panel 100, and the relative positions of the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113 and the photosensitive unit 114, the photosensitive unit 114 is arranged adjacent to the third sub-pixel 113, and the first sub-pixel 111 and the second sub-pixel 112 are relatively far away from the photosensitive unit 114. The third sub-pixel 113 can be used as a signal light source for the photosensitive unit 114, so that the photosensitive unit 114 can receive the light emitted by the third sub-pixel 113 and reflected by the object above the display panel 100, thereby realizing its sensing, recognition and other functions, and avoiding the light of other colors from causing stray light interference to the photosensitive unit 114.

[0110] On the basis of the above embodiment, two adjacent repeating units 110 in the same row are further arranged symmetrically about a symmetry axis parallel to the second direction y, and the repeating units 110 in the same column are arranged in a linear array along the second direction y. In this way, the arrangement of the multiple repeating units 110 of the display panel 100 is more regular, and the gap between adjacent repeating units 110 is smaller, which is convenient for the processing and manufacturing of the display panel 100, and can also improve the PPI of the display panel 100, thereby improving the display effect.

[0111] In the present application, the specific shapes of the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113 and the photosensitive unit 114 are not limited.

[0112] Further, the shape of the first sub-pixel 111 is a polygon, and the number of sides of the polygon is greater than or equal to 6, and further, the shape of the first sub-pixel 111 is a hexagon. Similarly, the shape of the second sub-pixel 112 is a polygon, and the number of sides of the polygon is greater than or equal to 6, and further, the shape of the second sub-pixel 112 is a hexagon. Similarly, the shape of the third sub-pixel 113 is a polygon, and the number of sides of the polygon is greater than or equal to 6, and further, the shape of the third sub-pixel 113 is a hexagon. Similarly, the shape of the photosensitive unit 114 is a trapezoid. The shapes of the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113 and the photosensitive unit 114 can also be octagons, nonagons, dodecagons, etc. It can be understood that the number of sides of the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113 and the photosensitive unit 114 varies according to their shapes, and is not specifically limited here.

[0113] In summary, by setting the shapes of the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113 and the photosensitive unit 114, their arrangement in the repeating unit 110 is made more reasonable, ensuring that the photosensitive unit 114 can evenly receive the reflected light from the third sub-pixel 113 within the maximum range, thereby improving its performance.

[0114] As described above, the shape of the first sub-pixel 111 can be polygonal, elliptical or circular. Figure 4 In the embodiment shown, the shape of the first sub-pixel 111 is a hexagon. Figure 3 And continue to read Figure 4 , the first sub-pixel 111 has a first side 1111 and a second side 1112, the first side 1111 is disposed adjacent to the second sub-pixel 112 in the same repeating unit 110, and the second side 1112 is disposed adjacent to the third sub-pixel 113 in the same repeating unit 110. Specifically, the light-emitting region of the first sub-pixel 111 has a first side 1111 and a second side 1112, the first side 1111 is disposed adjacent to the light-emitting region of the second sub-pixel 112 in the same repeating unit 110, and the second side 1112 is disposed adjacent to the light-emitting region of the third sub-pixel 113 in the same repeating unit 110, and further, the first side 1111 and the second side 1112 are disposed symmetrically about a symmetry axis parallel to the second direction y.

[0115] Furthermore, the first sub-pixel 111 also has a third side 1113 and a fourth side 1114. Specifically, the light-emitting area of ​​the first sub-pixel 111 also has a third side 1113 and a fourth side 1114. In two adjacent repeating units 110 along the second direction y, the third side 1113 of the first sub-pixel 111 of one repeating unit 110 is arranged adjacent to the second sub-pixel 112 in the other repeating unit 110; in two adjacent repeating units 110 along the second direction y, the fourth side 1114 of the first sub-pixel 111 of one repeating unit 110 is arranged adjacent to the third sub-pixel 113 in the other repeating unit 110.

[0116] Further, the third side 1113 and the fourth side 1114 are symmetrically arranged about a symmetry axis parallel to the second direction y, further, the first side 1111 and the fourth side 1114 are arranged opposite to and in parallel with each other, further, the second side 1112 and the third side 1113 are arranged opposite to and in parallel with each other.

[0117] Thus, by setting the shape and arrangement of the first sub-pixel 111, the gap between the first sub-pixel 111 and the second sub-pixel 112 and the third sub-pixel 113 can be reduced, thereby increasing the pixel density of the sub-pixels in the display panel 100 and improving the display effect.

[0118] As described above, the shape of the second sub-pixel 112 can be polygonal, elliptical or circular. Figure 5 In the embodiment shown, the shape of the second sub-pixel 112 is a hexagon. Figure 3 And continue to read Figure 5 In some embodiments, optionally, the second sub-pixel 112 has a fifth side 1121, and the fifth side 1121 is arranged adjacent to the first sub-pixel 111 in the same repeating unit 110. Specifically, the light-emitting area of ​​the second sub-pixel 112 has a fifth side 1121, and the fifth side 1121 is arranged adjacent to the light-emitting area of ​​the first sub-pixel 111 in the same repeating unit 110. Further, the fifth side 1121 and the first side 1111 are arranged opposite to and parallel to each other.

[0119] Furthermore, the second sub-pixel 112 also has a sixth side 1122. Specifically, the light-emitting area of ​​the second sub-pixel 112 also has a sixth side 1122. In two adjacent repeating units 110 along the second direction y, the sixth side 1122 of the second sub-pixel 112 of one repeating unit 110 is arranged adjacent to the first sub-pixel 111 in the other repeating unit 110.

[0120] Further, the sixth side 1122 and the third side 1113 are arranged opposite to each other and in parallel. Further, the fifth side 1121 and the sixth side 1122 are arranged symmetrically about a symmetry axis parallel to the first direction x.

[0121] By setting the shape and arrangement of the second sub-pixel 112 in this way, the gap between the second sub-pixel 112 and the first sub-pixel 111 and between multiple repeating units 110 can be reduced, thereby increasing the pixel density of the sub-pixels in the display panel 100 and improving the display effect.

[0122] As described above, the shape of the third sub-pixel 113 can be polygonal, elliptical or circular. Figure 6 In the embodiment shown, the shape of the second sub-pixel 112 is a hexagon. Figure 3 And continue to read Figure 6 In some embodiments, optionally, the third sub-pixel 113 has a seventh side 1131, and the seventh side 1131 is arranged adjacent to the first sub-pixel 111 in the same repeating unit 110. Specifically, the light-emitting area of ​​the third sub-pixel 113 has a seventh side 1131, and the seventh side 1131 is arranged adjacent to the light-emitting area of ​​the first sub-pixel 111 in the same repeating unit 110. Further, the seventh side 1131 and the second side 1112 are arranged opposite to and parallel to each other.

[0123] Furthermore, the third sub-pixel 113 also has an eighth side 1132. Specifically, the light-emitting area of ​​the third sub-pixel 113 also has an eighth side 1132. In two adjacent repeating units 110 along the second direction y, the eighth side 1132 of the third sub-pixel 113 of one repeating unit 110 is arranged adjacent to the first sub-pixel 111 in the other repeating unit 110.

[0124] Further, the eighth side 1132 and the fourth side 1114 are arranged opposite to each other and in parallel. Further, the seventh side 1131 and the eighth side 1132 are arranged symmetrically about a symmetry axis parallel to the first direction x.

[0125] Furthermore, the third sub-pixel 113 also has a ninth side 1133 . Specifically, the light-emitting region of the third sub-pixel 113 also has a ninth side 1133 . The ninth side 1133 is disposed adjacent to the photosensitive unit 114 in the same repeating unit 110 .

[0126] Further, the third sub-pixel 113 also has a tenth side 1134. Specifically, the light-emitting area of ​​the third sub-pixel 113 also has a tenth side 1134. The tenth side 1134 is arranged adjacent to the photosensitive unit 114 in the repeating unit 110 in the adjacent row. Further, the ninth side 1133 and the tenth side 1134 are symmetrically arranged about a symmetry axis parallel to the first direction x.

[0127] In this way, by setting the shape and arrangement of the third sub-pixel 113, the gap between the third sub-pixel 113 and the first sub-pixel 111 and the photosensitive unit 114 can be reduced, the pixel density of the sub-pixels in the display panel 100 is increased, and the display effect is improved.

[0128] As described above, the shape of the photosensitive unit 114 can be polygonal, elliptical or circular. Figure 7 In the embodiment shown, the shape of the photosensitive unit 114 is a hexagon. Figure 3 And continue to read Figure 7 In some embodiments, optionally, the photosensitive unit 114 has an eleventh side 1141, and the eleventh side 1141 is arranged adjacent to the third sub-pixel 113 in the same repeating unit 110. Further, the eleventh side 1141 and the ninth side 1133 are arranged opposite to and in parallel with each other. Further, the photosensitive unit 114 also has a twelfth side 1142, and the twelfth side 1142 is arranged adjacent to the light-emitting area of ​​the third sub-pixel 113 in the repeating unit 110 in an adjacent row. Further, the twelfth side 1142 and the tenth side 1134 are arranged opposite to and in parallel with each other. Further, the eleventh side 1141 and the twelfth side 1142 are arranged symmetrically about a symmetry axis parallel to the first direction x.

[0129] By setting the shape and arrangement of the photosensitive unit 114 in this way, the arrangement tightness between the photosensitive unit 114 and the third sub-pixel 113 can be improved, so that the photosensitive unit 114 can receive more light emitted by the third sub-pixel 113 and reflected by objects above the display panel 100.

[0130] Please continue reading Figure 2In order to improve the uniformity and linearity of the arrangement of each repeating unit 110 in the display panel 100, in some embodiments, optionally, the line connecting the corresponding positions of the light-emitting areas of the same-color sub-pixels in the same row is parallel to the first direction x, the line connecting the corresponding positions of the photosensitive units 114 in the same row is parallel to the first direction x, the line connecting the corresponding positions of the light-emitting areas of the same-color sub-pixels in the same column is parallel to the second direction y, the line connecting the corresponding positions of the photosensitive units 114 in the same column is parallel to the second direction y, the light-emitting area of ​​the first sub-pixel 111, the light-emitting area of ​​the second sub-pixel 112 and the light-emitting area of ​​the third sub-pixel 113 all have a second symmetry axis L2 parallel to the second direction y, the second symmetry axes L2 of the same-color sub-pixels in the same column are collinear, and the second direction y is perpendicular to the first direction x. This design makes the arrangement of the repeating unit 110 more uniform and linear, and the same-color sub-pixels are uniformly and regularly arranged, which is conducive to improving the overall display uniformity of the display panel 100.

[0131] In some embodiments, a plurality of third sub-pixels 113 are disposed at intervals around at least one photosensitive unit 114 .

[0132] Optionally, a plurality of third sub-pixels 113 are arranged at intervals around two photosensitive units 114 .

[0133] Optionally, the plurality of third sub-pixels 113 are disposed at intervals around at least one photosensitive unit 114. For example, the plurality of third sub-pixels 113 are disposed at intervals around two photosensitive units 114.

[0134] Taking the third sub-pixel 113 as a green sub-pixel as an example, the photosensitive unit 114 can be tightly surrounded by multiple third sub-pixels 113 (green sub-pixels), avoiding stray light interference from other colors to the photosensitive unit 114, and improving the signal-to-noise ratio of the photosensitive unit 114.

[0135] In some embodiments, two third sub-pixels 113 adjacent to each other along the first direction x among the plurality of third sub-pixels 113 surrounding at least one photosensitive unit 114 may be symmetrically arranged about a symmetry axis parallel to the second direction y; or two third sub-pixels 113 adjacent to each other along the second direction y among the plurality of third sub-pixels 113 surrounding at least one photosensitive unit 114 may be symmetrically arranged about a symmetry axis parallel to the first direction x; the first direction x and the second direction y are perpendicular to each other. Alternatively, two third sub-pixels 113 adjacent to each other along the first direction x among the plurality of third sub-pixels 113 surrounding at least one photosensitive unit 114 may be symmetrically arranged about a symmetry axis parallel to the second direction y, and two third sub-pixels 113 adjacent to each other along the second direction y among the plurality of third sub-pixels 113 surrounding at least one photosensitive unit 114 may be symmetrically arranged about a symmetry axis parallel to the first direction x.

[0136] In this way, the plurality of third sub-pixels 113 (green sub-pixels) can be uniformly surrounded by the photosensitive unit 114, thereby preventing light of other colors from causing stray light interference to the photosensitive unit 114. At the same time, the photosensitive unit 114 can uniformly receive light emitted by the plurality of third pixels and reflected by objects above the display panel 100, thereby improving the consistency of sensing signals around the photosensitive unit 114.

[0137] In some embodiments, in two adjacent repeating units 110 along the first direction x, the second sub-pixel 112 in one repeating unit 110 is disposed adjacent to the second sub-pixel 112 in the other repeating unit 110 .

[0138] It can be understood that the second sub-pixels 112 of the same color are arranged in the same row and adjacent to each other, so as to facilitate the use of the same mask to manufacture multiple second sub-pixels 112 .

[0139] In some embodiments, in two adjacent repeating units 110 along the second direction y, the second sub-pixel 112 in one repeating unit 110 is disposed adjacent to the second sub-pixel 112 in the other repeating unit 110 .

[0140] It can be understood that the second sub-pixels 112 of the same color are arranged in the same column, which is beneficial to the delicacy and linearity of the display effect.

[0141] In some embodiments, two adjacent photosensitive units 114 along the first direction x are spaced apart from each other.

[0142] Optionally, two photosensitive units 114 adjacent to each other along the first direction x are symmetrically arranged about a fourth symmetry axis parallel to the second direction y.

[0143] Optionally, two third sub-pixels 113 adjacent to each other along the first direction x are symmetrically arranged about the fourth symmetry axis L4 corresponding to the adjacent photosensitive units 114 (eg, Figure 8 As shown); two third sub-pixels 113 adjacent to each other along the second direction y are symmetrically arranged about the third symmetry axis L3 of the adjacent photosensitive unit 114.

[0144] In this way, the multiple third sub-pixels 113 (green sub-pixels) are symmetrically arranged with respect to the adjacent photosensitive units 114, which can prevent light of other colors from causing stray light interference to the photosensitive units 114, and also enable the photosensitive units 114 to uniformly receive light emitted by the multiple third pixels and reflected by objects above the display panel 100, thereby improving the consistency of the sensing signals around the photosensitive units 114.

[0145] In order to further reduce the stray light interference to the photosensitive unit 114, please combine Figure 1In some embodiments, optionally, the display panel 100 further includes an isolation structure 130 disposed on the substrate 120 , and the isolation structure 130 is disposed between at least a portion of the sub-pixels and the photosensitive unit 114 .

[0146] The isolation structure 130 can be made of opaque material, that is, in the display panel 100, an isolation structure 130 is provided between a portion of the photosensitive unit 114 and the sub-pixel adjacent thereto. Exemplarily, the isolation structure 130 is arranged between the photosensitive unit 114 and the third sub-pixel 113, or the isolation structure 130 is arranged between the photosensitive unit 114 and the first sub-pixel 111, or the isolation structure 130 is arranged between the photosensitive unit 114 and the second sub-pixel 112, or the isolation structure 130 is arranged between the photosensitive unit 114 and the first sub-pixel 111, and between the photosensitive unit 114 and the third sub-pixel 113 at the same time.

[0147] In some other embodiments, an isolation structure 130 is provided between a portion of two adjacent sub-pixels, or an isolation structure 130 is provided between each photosensitive unit 114 and its adjacent sub-pixel, or an isolation structure 130 is provided between every two adjacent sub-pixels.

[0148] like Figure 1 As shown, a portion of the light emitted by the sub-pixel, as shown by the dotted line with an arrow in the figure, is blocked by the isolation structure 130 and cannot irradiate the photosensitive unit 114, and another portion of the light emitted by the sub-pixel, as shown by the solid line with an arrow in the figure, passes through the isolation structure 130 and is reflected by an object above the display panel 100, such as a finger, and thus irradiates the photosensitive unit 114 and is received by it.

[0149] Due to the existence of the isolation structure 130, the photosensitive unit 114 and the sub-pixel located on both sides thereof are separated, or the two sub-pixels located on both sides thereof are separated, so that part of the light emitted by the sub-pixel is blocked by the isolation structure 130 and cannot be received by the photosensitive unit 114, thereby reducing stray light interference to the photosensitive unit 114.

[0150] It should be noted that the isolation structure 130 is only Figure 1 The isolation structure 130 is shown in the overall structure of the display panel 100, while in other structural schematic diagrams of the repeating unit 110 and the structural schematic diagrams of the sub-pixel, the isolation structure 130 is not shown, but it does not mean that the isolation structure 130 does not exist.

[0151] In addition, during the manufacturing process of the display panel 100 with the isolation structure 130, the formation of its sub-pixels does not need to be carried out by evaporation with the help of a mask plate. The isolation structure 130 can replace the role of the mask plate. With the help of the separation of the isolation structure 130, the distance between two adjacent sub-pixels or two repeating units 110 can be shortened, making the arrangement between sub-pixels or repeating units 110 more compact, achieving a higher PPI, thereby improving the manufacturing accuracy of sub-pixels or repeating units 110. It is also convenient to manufacture sub-pixels or photosensitive units 114 of different shapes and structures according to different usage requirements.

[0152] As described above, the isolation structure 130 is provided in the display panel 100 so that the photosensitive unit 114 and the sub-pixel located on both sides thereof are isolated, or the two sub-pixels located on both sides thereof are isolated, so that the light emitted by the sub-pixel is partially blocked by the isolation structure 130 and cannot be received by the photosensitive unit 114, thereby reducing the stray light interference to the photosensitive unit 114. On this basis, the isolation structure 130 can be an integrated structure, or the isolation structure 130 can include relatively independent multi-segment structures, such as Figure 1 As shown, optionally, the isolation structure 130 includes an isolation spacer 131 and a blocking portion 132, the blocking portion 132 is located on the side of the isolation spacer 131 away from the substrate 120, and the orthographic projection of the isolation spacer 131 on the substrate 120 is located within the orthographic projection of the blocking portion 132 on the substrate 120, that is, the orthographic projection of the blocking portion 132 on the substrate 120 covers a larger area, while the orthographic projection of the isolation spacer 131 on the substrate 120 covers a relatively small area, so that the orthographic projection of the blocking portion 132 on the substrate 120 can cover the orthographic projection of the isolation spacer 131 on the substrate 120. The cross-sectional shapes of the isolation spacer 131 and the blocking portion 132 can be regular shapes, such as rectangles, triangles, etc., or irregular shapes.

[0153] Optionally, the display panel 100 further includes a pixel defining layer 140, the pixel defining layer 140 defines a plurality of pixel openings 141 spaced apart from each other, the sub-pixel is at least partially located in the pixel opening 141, and the isolation structure 130 is disposed on the pixel defining layer 140. The sub-pixel includes a first electrode 115, a light-emitting region 116, and a second electrode 117 stacked in sequence, and the first electrode 115 is at least partially exposed by the pixel opening 141. The pixel defining layer 140 of the display panel 100 can be disposed in the same layer as the first electrode 115 of the sub-pixel, and the first electrode 115 of the sub-pixel is at least partially exposed by the pixel opening 141, so as to facilitate normal light emission of the sub-pixel. The light-emitting region 116 of the sub-pixel is disposed in the pixel opening 141 to avoid cross-color or interference between adjacent sub-pixels. The light-emitting region 116 and the first electrode 115 in the sub-pixel are separated by the isolation structure 130, wherein the first electrode 115 may be an anode layer or a cathode layer, and the first electrode 115 is disposed on the light-emitting region 116, and the light-emitting region 116 is covered by the first electrode 115 and does not contact the isolation structure 130. Therefore, in some embodiments, the pixel edge of the sub-pixel is the boundary of the pixel opening 141 of the pixel defining layer 140, and the area of ​​the pixel opening 141 is the light-emitting area of ​​the sub-pixel.

[0154] The display panel 100 provided in the embodiment of the present application may further include an encapsulation layer, a module structure and a cover plate arranged on a side of the second electrode 117 away from the substrate 120 .

[0155] Fig. 9 A schematic diagram of the overall structure of a display device 10 provided in one embodiment of the present application is shown.

[0156] Please combine Figure 1 Also see Fig. 9 The embodiment of the present application further provides a display device 10 , which includes a display panel 100 and an identification circuit as in any of the above embodiments, and the identification circuit is electrically connected to a photosensitive unit 114 .

[0157] The display panel 100 disclosed in any of the above embodiments of the present application is applied to a display device 10 to provide a screen display function. The display device 10 may be any product or component with a display function, including but not limited to a mobile phone, a tablet computer, a laptop computer, an e-reader, a wearable device, a remote control, a television, a desktop computer, a vehicle-mounted device, etc. In the display device 10, when a finger is placed above the photosensitive element in the fingerprint recognition element, the light emitted by the light source is incident on the valleys and ridges of the finger, and is incident on the photosensitive element after reflection. Since the light intensities reflected from the valleys and ridges of the finger to the photosensitive element are different, the photocurrent generated by the photosensitive element is different, and then the recognition circuit can obtain the fingerprint pattern of the finger according to different photoelectric signals.

[0158] The display device 10 of the embodiment of the present application improves the aperture ratio of the display panel 100 by staggering the first sub-pixel 111 and the photosensitive unit 114 in any repeating unit 110 in the display panel 100 with the second sub-pixel 112 and the third sub-pixel 113 in different rows, and arranges at least a portion of the photosensitive unit 114 adjacent to the third sub-pixel 113, so that the photosensitive unit 114 can easily receive the light emitted by the third pixel and reflected by the object above the display panel 100, thereby reducing the stray light interference to the photosensitive unit 114 and improving the performance of the photosensitive unit 114.

[0159] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0160] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
