[0076] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0077] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, they do not represent any order, quantity or importance, but are only used to distinguish different components. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present application, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element. "Include" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0078] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0079] In the relevant OLED display technology, the fingerprint recognition function is realized by integrating the OPD (Organic Photodiode) unit into the OLED display panel. The main principle is: the finger reflects the light emitted by the OLED light-emitting unit to the OPD unit, and the OPD unit converts the optical signal into an electrical signal, thereby realizing the recognition of the user's fingerprint information. However, on the one hand, the OPD unit can only receive light of a specific wavelength. During the fingerprint recognition process, due to the weak light received by the OPD unit and the interference of stray light and other factors, the OLED display panel has the problem of low fingerprint recognition sensitivity; on the other hand, the OPD unit occupies the light-emitting area, resulting in a decrease in the aperture ratio of the OLED display panel, which is not only not conducive to improving the PPI, but also reduces the display effect.

[0080] In view of at least one of the above problems, the embodiments of the present application provide a pixel arrangement structure, a display panel, and a display device, wherein the first sub-pixel and the light sensing unit are arranged in pairs, and the first sub-pixel and the light sensing unit are located within a first virtual polygon, and the adjacent sides of the first sub-pixel and the light sensing unit are parallel to each other. In this way, the first sub-pixel and the light sensing unit are arranged more compactly, thereby improving the aperture ratio, and further improving the display effect.

[0081] For a better understanding, some explanations are given before going into detail:

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] First, refer to Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a pixel arrangement structure 11, which includes a plurality of pixel groups 11a. The plurality of pixel groups 11a are arranged in rows along a first direction X, and arranged in columns along a second direction Y intersecting the first direction X. The pixel group 11a includes at least one first sub-pixel 111 and at least one light sensing unit 112, and the first sub-pixel 111 and the light sensing unit 112 correspond to each other one by one and are arranged in pairs, that is, one first sub-pixel 111 and one light sensing unit 112 constitute a pair.

[0087] In the first sub-pixel 111 and the light sensing unit 112 arranged in pairs, the first sub-pixel 111 and the light sensing unit 112 are arranged at intervals along the second direction Y, the first sub-pixel 111 has a first side 1111 and a second side 1112 intersecting the second direction Y, and the light sensing unit 112 has a third side 1121 and a fourth side 1122 intersecting the second direction Y.

[0088] The first side 1111, the second side 1112, the third side 1121 and the fourth side 1122 overlap with the four sides of a first virtual polygon 121. In other words, four virtual straight lines respectively overlapping with the first side 1111, the second side 1112, the third side 1121 and the fourth side 1122 constitute the four sides of the first virtual polygon 121. The first sub-pixel 111 and the light sensing unit 112 arranged in pairs are located in the first virtual polygon 121, and the adjacent sides of the first sub-pixel 111 and the light sensing unit 112 are parallel to each other.

[0089] It is understandable that the first virtual polygon 121 can be a virtual quadrilateral, a virtual pentagon, a virtual hexagon, etc. It should be noted that the pixel group 11a refers to: the smallest repeating unit of the repeated arrangement in the pixel arrangement structure 11. The first sub-pixel 111 can be one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel. Of course, in some other embodiments, the first sub-pixel 111 can also be a sub-pixel that emits other colors of light besides red, green, and blue, for example, white or yellow, which is not limited in the embodiments of the present application.

[0090] In the embodiment of the present application, the first sub-pixel 111 and the light sensing unit 112 are arranged in pairs in a one-to-one correspondence, and a pair of the first sub-pixel 111 and the light sensing unit 112 are located within the first virtual polygon 121. In this way, the first sub-pixel 111 and the light sensing unit 112 are arranged compactly, which is beneficial to improve the PPI. By making the adjacent sides of the first sub-pixel 111 and the light sensing unit 112 parallel to each other, the distance between the first sub-pixel 111 and the light sensing unit 112 can be made close enough, which is beneficial to reduce the space between the first sub-pixel 111 and the light sensing unit 112, thereby improving the aperture ratio.

[0091] In one embodiment, the pixel group 11a further includes at least one second sub-pixel 113, and the second sub-pixel 113 and the first sub-pixel 111 emit light of different colors, and the light sensing unit 112 is configured to receive the light emitted by the second sub-pixel 113 reflected by the sensed object. Exemplarily, the light sensing unit 112 may be an OPD (Organic Photodiode), and the sensed object may be a user's finger. The second sub-pixel 113 may be one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel. Of course, in some other embodiments, the second sub-pixel 113 may also be a sub-pixel that emits light of other colors besides red, green, and blue, for example, white or yellow, which is not limited in the embodiments of the present application.

[0092] In the same pixel group 11a, at least one light sensing unit 112 is disposed adjacent to at least one second sub-pixel 113. Here, the light sensing unit 112 and the second sub-pixel 113 being adjacent means that there is no other sub-pixel between the light sensing unit 112 and the second sub-pixel 113.

[0093] The above configuration can increase the amount of identifiable light reflected by the sensed object (such as the light emitted by the first sub-pixel 111 ) received by the light sensing unit 112 , thereby improving the sensing accuracy (fingerprint recognition sensitivity).

[0094] In one embodiment, the pixel group 11a includes a plurality of second sub-pixels 113. In the same pixel group 11a, at least one light sensing unit 112 is disposed adjacent to the plurality of second sub-pixels 113. In this way, the amount of identifiable light reflected by the sensed object (such as light emitted by the first sub-pixel 111) received by the light sensing unit 112 can be further increased, thereby improving the sensing accuracy (fingerprint recognition sensitivity).

[0095] In one embodiment, referring to Figure 2As shown, in the same pixel group 11a, at least one light sensing unit 112 has second sub-pixels 113 on two opposite sides along the first direction X. For example, the light sensing unit 112 at the lower right has second sub-pixels 113 on two opposite sides along the first direction X.

[0096] Furthermore, the third side 1121 of the light sensing unit 112 is adjacent to and parallel to one side of a second sub-pixel 113, and the fourth side 1122 of the light sensing unit 112 is adjacent to and parallel to one side of another second sub-pixel 113. In this way, on the one hand, the light sensing unit 112 and the second sub-pixel 113 can have a larger adjacent area, ensuring that the light sensing unit 112 can receive the light emitted from the adjacent second sub-pixel 113 to the greatest extent; on the other hand, the distance between the second sub-pixel 113 and the light sensing unit 112 can be made close enough, which is conducive to reducing the space between the second sub-pixel 113 and the light sensing unit 112, thereby improving the aperture ratio.

[0097] In one embodiment, the pixel group 11a further includes at least one third sub-pixel 114, and the colors of light emitted by the third sub-pixel 114, the first sub-pixel 111, and the second sub-pixel 113 are different. Exemplarily, the third sub-pixel 114 can be one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel. Of course, in some other embodiments, the third sub-pixel 114 can also be a sub-pixel that emits other colors of light besides red, green, and blue, for example, white or yellow, which is not limited in the embodiments of the present application.

[0098] Furthermore, in the same pixel group 11a, the number ratio of the first sub-pixel 111, the second sub-pixel 113, the third sub-pixel 114 and the light sensing unit 112 is 1:2:1:1. In this way, the first sub-pixel 111, the second sub-pixel 113 and the third sub-pixel 114 can satisfy the pixel borrowing relationship, thereby achieving a higher aperture ratio and PPI through the pixel borrowing relationship, achieving a more delicate display effect, and improving the display life.

[0099] In one embodiment, the pixel group 11a includes two first sub-pixels 111, four second sub-pixels 113, two third sub-pixels 114, and two light sensing units 112. In this way, on the one hand, the first sub-pixel 111, the second sub-pixel 113, and the third sub-pixel 114 can satisfy the pixel borrowing relationship, thereby achieving a higher aperture ratio and PPI through the pixel borrowing relationship, achieving a more delicate display effect, and improving the display life; on the other hand, the number of light sensing units 112 can be increased to the maximum extent, thereby improving the fingerprint recognition sensitivity of the display panel 10.

[0100] In one embodiment, in the same pixel group 11a, each first sub-pixel 111 is adjacent to at least one second sub-pixel 113, and each third sub-pixel 114 is adjacent to at least one second sub-pixel 113. This is conducive to borrowing between pixels, so that a higher aperture ratio and PPI can be achieved through the pixel borrowing relationship, a more delicate display effect can be achieved, and the display life can be improved.

[0101] In one embodiment, referring to Figure 1 and Figure 2 As shown, in the same pixel group 11a, one first sub-pixel 111 is adjacent to two second sub-pixels 113, and another first sub-pixel 111 is adjacent to one second sub-pixel 113. Specifically, the first sub-pixel 111 located at the lower right is adjacent to two second sub-pixels 113, and the first sub-pixel 111 located at the upper left is adjacent to one second sub-pixel 113.

[0102] This is conducive to borrowing between pixels, thereby achieving a higher aperture ratio and PPI through the pixel borrowing relationship, achieving a more delicate display effect, and improving the display life.

[0103] In one embodiment, referring to Figure 1 and Figure 2 As shown, in the same pixel group 11 a , each third sub-pixel 114 is adjacent to two second sub-pixels 113 .

[0104] This is conducive to borrowing between pixels, thereby achieving a higher aperture ratio and PPI through the pixel borrowing relationship, achieving a more delicate display effect, and improving the display life.

[0105] In one embodiment, in the same pixel group 11a, the center line connecting the four second sub-pixels 113 forms a quadrilateral. For example, the quadrilateral may be a rectangle, a parallelogram, or a trapezoid.

[0106] In one embodiment, in the same pixel group 11a, the center line connecting the four second sub-pixels 113 is a regular quadrilateral, so that the second sub-pixels 113 can be easily arranged, which is beneficial to improving the display effect.

[0107] In one embodiment, in the same pixel group 11a, the center line connecting the two first virtual polygons 121 and the two third sub-pixels 114 is a quadrilateral. For example, the quadrilateral may be a rectangle, a parallelogram, or a trapezoid.

[0108] In one embodiment, in the same pixel group 11a, the center line connecting the two first virtual polygons 121 and the two third sub-pixels 114 is a regular quadrilateral. In this way, the arrangement of the first sub-pixel 111, the light sensing unit 112 and the third sub-pixel 114 can be more regular, which is convenient for borrowing between sub-pixels, and is conducive to achieving a higher aperture ratio and PPI through the pixel borrowing relationship, and can achieve a more delicate display effect.

[0109] In one embodiment, in the same pixel group 11 a , a line connecting the centers of four second sub-pixels 113 forms a second virtual quadrilateral 122 , and the center of a first virtual polygon 121 coincides with the center of the second virtual quadrilateral 122 .

[0110] This helps to make the sub-pixel arrangement more regular, facilitates borrowing between sub-pixels, and helps to achieve a higher aperture ratio and PPI through pixel borrowing relationships, thereby achieving a more delicate display effect.

[0111] In one embodiment, in the same pixel group 11 a , a line connecting the centers of two first virtual polygons 121 and two third sub-pixels 114 forms a third virtual quadrilateral 123 , and the center of a second sub-pixel 113 coincides with the center of the third virtual quadrilateral 123 .

[0112] This helps to make the sub-pixel arrangement more regular, facilitates borrowing between sub-pixels, and helps to achieve a higher aperture ratio and PPI through pixel borrowing relationships, thereby achieving a more delicate display effect.

[0113] In one embodiment, in the pixel arrangement structure 11 , all the light sensing units 112 are arranged in rows along the first direction X and in columns along the second direction Y. In this way, the light sensing units 112 can be arranged more evenly, which is beneficial to improving sensing uniformity.

[0114] In one embodiment, in the pixel arrangement structure 11, the third side 1121 of each light sensing unit 112 is adjacent to and parallel to one side of a second sub-pixel 113, and the fourth side 1122 of the light sensing unit 112 is adjacent to and parallel to one side of another second sub-pixel 113. In this way, on the one hand, the light sensing unit 112 and the second sub-pixel 113 can have a larger adjacent area, ensuring that the light sensing unit 112 can receive the light emitted from the adjacent second sub-pixel 113 to the greatest extent; on the other hand, the distance between the second sub-pixel 113 and the light sensing unit 112 can be made close enough, which is conducive to reducing the space between the second sub-pixel 113 and the light sensing unit 112, thereby improving the aperture ratio.

[0115] In one embodiment, in the pixel arrangement structure 11, all first sub-pixels 111 are arranged in rows along the first direction X and in columns along the second direction Y. In this way, when performing pure color display, not only can the linearity of the display be improved, but also the color edge phenomenon during pure color display can be improved.

[0116] In one embodiment, in the pixel arrangement structure 11, all the second sub-pixels 113 are arranged in rows along the first direction X and in columns along the second direction Y. In this way, when performing pure color display, not only can the linearity of the display be improved, but also the color edge phenomenon during pure color display can be improved.

[0117] In one embodiment, in the pixel arrangement structure 11, all the third sub-pixels 114 are arranged in rows along the first direction X and in columns along the second direction Y. In this way, when performing pure color display, not only can the linearity of the display be improved, but also the color edge phenomenon during pure color display can be improved.

[0118] Reference Figure 1 As shown, by arranging the paired first sub-pixels 111 and light sensing units 112 at intervals along the second direction Y, the first sub-pixels 111, the second sub-pixels 113 and the third sub-pixels 114 are conveniently used in the horizontal direction. Figure 1 The triangles in represent the borrowing relationship between the sub-pixels in the horizontal direction.

[0119] Reference Figure 4 As shown, Figure 2 The pixel group 11a shown is rotated 90° counterclockwise and arranged along the first direction X and the second direction Y, forming Figure 4 The pixel arrangement structure 11 shown in the figure. In this structure, each sub-pixel borrows from each other in the horizontal direction, and the first sub-pixel 111 and the light sensing unit 112 are arranged at intervals along the first direction X. The light sensing unit 112 is likely to affect the borrowing of each pixel in the horizontal direction. It can be understood that in Figure 4 In the pixel arrangement structure 11 shown, when each sub-pixel borrows in the vertical direction, the light sensing unit 112 will not affect the borrowing relationship of each sub-pixel.

[0120] In one embodiment, referring to Figure 3 As shown, the lengths of the first side 1111 and the second side 1112 are equal. Figure 3 Taking the orientation shown as an example, in this way, the first sub-pixel 111 can have equal lengths on the left and right sides, so that when the first sub-pixel 111 borrows from the sub-pixels on the left and right sides respectively, the luminous effects on the left and right sides can be consistent, which is beneficial to improving display uniformity and display effect.

[0121] In one embodiment, the first side 1111 and the second side 1112 both intersect with the second direction Y.

[0122] In one embodiment, the first virtual polygon 121 is defined to have a first center line a parallel to the second direction Y. The first sub-pixel 111 further includes a fifth side 1113, the fifth side 1113 is located at a side of the first sub-pixel 111 close to the light sensing unit 112, and the first side 1111 and the second side 1112 are respectively located at two sides of the first center line a along the first direction X.

[0123] In one embodiment, the angle between the first side 1111 and the fifth side 1113 is equal to the angle between the second side 1112 and the fifth side 1113. For example, the angle between the first side 1111 and the fifth side 1113 is 45°, and the angle between the second side 1112 and the fifth side 1113 is 45°. In this way, the first sub-pixels 111 can be arranged more evenly, which is conducive to improving the display effect.

[0124] In one embodiment, the shape of the first sub-pixel 111 is an isosceles triangle. In this way, the two waists of the first sub-pixel 111 are respectively adjacent to a second sub-pixel 113, which is convenient for borrowing between sub-pixels, and is conducive to achieving a higher aperture ratio and PPI through the pixel borrowing relationship, and can achieve a more delicate display effect.

[0125] In one embodiment, referring to Figure 5 , Figure 6 and Figure 7 As shown, the first sub-pixel 111 further includes a sixth edge 1114 , which is located on a side of the first sub-pixel 111 away from the light sensing unit 112 , and two ends of the sixth edge 1114 are respectively connected to the first edge 1111 and the second edge 1112 .

[0126] In one embodiment, the shape of the first sub-pixel 111 is an isosceles trapezoid, so that the shape of the first sub-pixel 111 can be more diverse, which is helpful to reduce the manufacturing difficulty.

[0127] In one embodiment, referring to Figure 8 , Fig. 9 and Fig.10 As shown, the first sub-pixel 111 also includes a seventh side 1115 and an eighth side 1116, and the seventh side 1115 and the eighth side 1116 are respectively located on both sides of the first center line a along the first direction X; one end of the seventh side 1115 is connected to the fifth side 1113, and the other end is connected to the first side 1111; one end of the eighth side 1116 is connected to the fifth side 1113, and the other end is connected to the second side 1112.

[0128] It should be noted that the light sensing unit 112 is a light absorbing material. When the light sensing unit 112 is evaporated, the material of the light sensing unit 112 is evaporated to the adjacent sub-pixel, which easily leads to quenching of the light emitting material. By setting the seventh side 1115 and the eighth side 1116, it is helpful to expand the occupied space of the first sub-pixel 111 in the first virtual polygon 121, thereby reducing the occupied space of the light sensing unit 112, thereby helping to reduce the impact of the light sensing unit 112 on the first sub-pixel 111 and prolonging the service life of the first sub-pixel 111.

[0129] In one embodiment, referring to Figure 3 and Figure 7 As shown, the shape of the first sub-pixel 111 is the same as the shape of the light sensing unit 112. In this way, the openings on the mask can be made more uniform, which is beneficial to improving the uniformity of the structural strength of the mask.

[0130] In one embodiment, if Figure 3 As shown, the lengths of the third side 1121 and the fourth side 1122 are equal. Figure 3 Taking the orientation shown as an example, the light sensing unit 112 can have equal lengths on the left and right sides, so that the light sensing unit 112 and the second sub-pixels 113 on the left and right sides have equal adjacent areas, which is beneficial to improving the uniformity of sensing.

[0131] In one embodiment, the third side 1121 and the fourth side 1122 both intersect with the second direction Y.

[0132] In one of the embodiments, the first virtual polygon 121 is defined to have a first center line a parallel to the second direction Y. The light sensing unit 112 further includes a ninth side 1123, the ninth side 1123 is located on a side of the light sensing unit 112 close to the first sub-pixel 111, and the third side 1121 and the fourth side 1122 are respectively located on both sides of the first center line a along the first direction X. Further, the ninth side 1123 of the light sensing unit 112 is adjacent to and parallel to the fifth side 1113 of the first sub-pixel 111. The distance between the first sub-pixel 111 and the light sensing unit 112 can be made close enough, which is conducive to reducing the space between the first sub-pixel 111 and the light sensing unit 112, thereby improving the aperture ratio.

[0133] In one embodiment, the angle between the third side 1121 and the ninth side 1123 is equal to the angle between the fourth side 1122 and the ninth side 1123. For example, the angle between the third side 1121 and the ninth side 1123 is 45°, and the angle between the fourth side 1122 and the ninth side 1123 is 45°. In this way, the light sensing units 112 can be arranged more evenly, which is conducive to improving the fingerprint recognition performance.

[0134] In one embodiment, the light sensing unit 112 is in the shape of an isosceles triangle. Thus, the two waists of the light sensing unit 112 are respectively adjacent to a second sub-pixel 113. Thus, on the one hand, the light sensing unit 112 and the second sub-pixel 113 can have a larger adjacent area, ensuring that the light sensing unit 112 can receive the light emitted from the adjacent second sub-pixel 113 to the greatest extent; on the other hand, the distance between the second sub-pixel 113 and the light sensing unit 112 can be made close enough, which is conducive to reducing the space between the second sub-pixel 113 and the light sensing unit 112, thereby improving the aperture ratio.

[0135] In one embodiment, referring to Figure 7 and Fig.10 As shown, the light sensing unit 112 further includes a tenth side 1124, which is located on the side of the light sensing unit 112 away from the first sub-pixel 111, and the two ends of the tenth side 1124 are respectively connected to the third side 1121 and the fourth side 1122. In this way, it is helpful to reduce the space occupied by the light sensing unit 112, thereby helping to reduce the impact of the light sensing unit 112 on the first sub-pixel 111 during evaporation, and improving the service life of the first sub-pixel 111.

[0136] In one embodiment, the shape of the light sensing unit 112 is an isosceles trapezoid, so that the shape of the light sensing unit 112 can be more diverse, which is helpful to reduce the manufacturing difficulty.

[0137] In one embodiment, referring to Fig.11 , Fig.12 and Fig.13 As shown, the light sensing unit 112 further includes an eleventh side 1125 and a twelfth side 1126, and the eleventh side 1125 and the twelfth side 1126 are respectively located on both sides of the first center line a along the first direction X. One end of the eleventh side 1125 is connected to the ninth side 1123, and the other end is connected to the third side 1121. One end of the twelfth side 1126 is connected to the ninth side 1123, and the other end is connected to the fourth side 1122. In this way, it is beneficial to reduce the occupied space of the light sensing unit 112, and further to reduce the influence of the light sensing unit 112 on the first sub-pixel 111 during evaporation, thereby improving the service life of the first sub-pixel 111.

[0138] In one embodiment, the first virtual polygon 121 is a quadrilateral. For example, the quadrilateral may be a rectangle, a parallelogram, or a trapezoid.

[0139] In one embodiment, the first virtual polygon 121 is a regular quadrilateral, so that the first sub-pixel 111 and the light sensing unit 112 can be arranged more compactly and regularly, which is beneficial to improving the aperture ratio.

[0140] In one embodiment, the adjacent sides of the first sub-pixel 111 and the second sub-pixel 113 are straight sides and parallel to each other. In this way, the distance between the first sub-pixel 111 and the second sub-pixel 113 can be made close enough, which is conducive to reducing the space between the first sub-pixel 111 and the second sub-pixel 113, thereby improving the aperture ratio.

[0141] In one embodiment, the adjacent sides of the second sub-pixel 113 and the third sub-pixel 114 are straight sides and parallel to each other. In this way, the distance between the second sub-pixel 113 and the third sub-pixel 114 can be made close enough, which is conducive to reducing the space between the second sub-pixel 113 and the third sub-pixel 114, thereby improving the aperture ratio.

[0142] In one embodiment, the second sub-pixel 113 is in the shape of a quadrilateral. For example, the quadrilateral may be a rectangle, a parallelogram, or a trapezoid.

[0143] In one embodiment, the second sub-pixel 113 is in the shape of a regular quadrilateral.

[0144] In one embodiment, the third sub-pixel 114 is in the shape of a quadrilateral. For example, the quadrilateral may be a rectangle, a parallelogram, or a trapezoid.

[0145] In one embodiment, the third sub-pixel 114 is in the shape of a regular quadrilateral.

[0146] It should be noted that, in the embodiment of the present application, the first sub-pixel 111 is an R pixel, the second sub-pixel 113 is a G pixel, and the third sub-pixel 114 is a B pixel. Fig.14 As shown, the present application lists two pixel arrangement methods, namely method a and method b. In method a, the third sub-pixel 114 is a square, the light sensing unit 112 and the first sub-pixel 111 are arranged in pairs and are located in a virtual square, and the adjacent sides of the light sensing unit 112 and the first sub-pixel 111 are parallel to each other. In method b, the first sub-pixel 111 is a square, the light sensing unit 112 and the third sub-pixel 114 are arranged in pairs and are located in a virtual square, and the adjacent sides of the light sensing unit 112 and the third sub-pixel 114 are parallel to each other.

[0147] Furthermore, combined with Fig.14 and Fig.15 , compare the luminous area of ​​method a and method b, from Fig.15As can be seen from the figure, when the light sensing unit 112 and the third sub-pixel 114 are arranged in pairs, the third sub-pixel 114 changes from a quadrilateral to a pentagon, resulting in an additional corner for the third sub-pixel 114. Generally, chamfers are usually set at the corners of sub-pixels. Therefore, the third sub-pixel 114 in the b method has two more chamfers with larger angles than the third sub-pixel 114 in the a method, resulting in a loss of light-emitting area, such as Fig.15 In summary, compared with the method of arranging the light sensing unit 112 and the third sub-pixel 114 in a first virtual polygon 121, and making the adjacent sides of the two parallel to each other, the embodiment of the present application arranges the light sensing unit 112 and the first sub-pixel 111 in a first virtual polygon 121, and makes the adjacent sides of the two parallel to each other, which is beneficial to maximize the pixel opening area when a large number of light sensing units 112 are introduced into the pixel arrangement structure 11, and reduces the risk of reducing the opening area.

[0149] Specifically, the display panel 10 may be an organic light emitting diode display (Organic Light Emitting Diode, OLED) or a quantum dot electroluminescent display (Quantum Dot Light Emitting Diodes, QLED).

In this way, the first sub-pixel 111 and the light sensing unit 112 are arranged more compactly, thereby improving the aperture ratio and further improving the display effect.

[0151] Thirdly, refer to Fig.16 As shown, an embodiment of the present application provides a display device 1, comprising the display panel 10 in the second aspect.

[0152] The display device 1 can be a laptop computer, a mobile phone, a wireless device, a personal digital assistant (PDA), a handheld or portable computer, a GPS receiver / navigator, a camera, an MP4 video player, a camcorder, a game console, a watch, a clock, a calculator, a television monitor, a flat-panel display, a computer monitor, a car display (e.g., an odometer display, etc.), a navigator, a cockpit controller and / or display, a display of a camera view (e.g., a display of a rearview camera in a vehicle), an electronic photo, an electronic billboard or sign, a projector, etc.

[0153] The display device 1 provided in the embodiment of the present application arranges the first sub-pixel 111 and the light sensing unit 112 in pairs, places the first sub-pixel 111 and the light sensing unit 112 in the first virtual polygon 121, and makes the adjacent sides of the first sub-pixel 111 and the light sensing unit 112 parallel to each other. In this way, the first sub-pixel 111 and the light sensing unit 112 are arranged more compactly, thereby improving the aperture ratio and further improving the display effect.
