[0089] 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.

[0090] 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 element. 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. "Including" 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.

[0091] 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.

[0092] For a better understanding, some explanations are given before going into detail:

[0093] 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.

[0094] 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.

[0095] 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.

[0096] FMM (Fine Metal Mask): also known as a high-precision metal mask, used in the OLED evaporation process.

[0097] At present, display devices integrate more and more functional structures. In order to enable users to protect the information of the display content of the display device, the display device is encrypted and the fingerprint information is identified. The OLED display panel is integrated with the light sensing unit to form a display device with a fingerprint recognition function for users to use. However, the existing light sensing unit requires a higher detection sensitivity. When it is interfered by the light signal, its signal recognition will be reduced, affecting the fingerprint recognition effect of the display device.

[0098] In order to reduce the interference of the light signal received by the light sensing unit, thereby improving the effect of fingerprint recognition of the display device, in the related technology, a light shielding layer is set to reduce the interference of stray light (here stray light is the light that affects the detection of the light sensing unit) on the light sensing unit, thereby improving the effect of fingerprint recognition of the display device.

[0099] However, on the one hand, setting up a light shielding layer requires adding additional functional structural layers, which increases the complexity and difficulty of designing and manufacturing the display device; on the other hand, the positions of the light sensing unit and the light shielding layer affect the spatial position borrowing of the sub-pixels, which may cause white light recombination problems in the display device, affecting the normal display of the display device.

[0100] It should be noted that the display panel is used as a display structure of a display device to display information such as images, pictures, text, and videos. The light sensing unit is a photodetector that can convert light into a current or voltage signal according to the mode of use. The light sensing unit is very sensitive to changes in light, and the electrical characteristics will change when the light intensity is different. The light intensity can be used to change the current in the circuit. Exemplarily, the light sensing unit can be a photosensitive diode. Here, only a photosensitive diode is used as an example of a light sensing unit. Of course, the type of light sensing unit is not limited to this.

[0101] First, refer to Figure 1 and Figure 2As shown, the embodiment of the present application provides a pixel arrangement structure 11, including a plurality of pixel groups 111, each pixel group 111 includes at least one first sub-pixel 111a, at least one second sub-pixel 111b, at least one third sub-pixel 111c and a plurality of light sensing units 111d. The first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c are respectively used to emit light of different colors; the light sensing unit 111d is configured to receive the light emitted by the first sub-pixel 111a reflected by the sensed object. Among them, the light sensing unit 111d and the first sub-pixel 111a are both polygonal, the light sensing unit 111d includes a first side 111d1, the length of the first side 111d1 is greater than the length of the other side of the light sensing unit 111d, the first sub-pixel 111a includes a second side 111a1, the length of the second side 111a1 is greater than the length of the other side of the first sub-pixel 111a; the first side 111d1 is adjacent to the second side 111a1.

[0102] The pixel arrangement structure 11 provided in the embodiment of the present application is provided with a first sub-pixel 111a, a second sub-pixel 111b, a third sub-pixel 111c and a light sensing unit 111d. The first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c are respectively used to emit light of different colors; the light sensing unit 111d is configured to receive the light emitted by the first sub-pixel 111a reflected by the sensed object, and the first side 111d1 of the light sensing unit 111d is adjacent to the second side 111a1 of the first sub-pixel 111a. In this way, the first side 111d1 and the second side 111a1 can be adjacent to each other, so that the light sensing unit 111d and the first sub-pixel 111a have a larger adjacent area, so that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a, and the light sensing unit 111d can maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0103] It should be noted that the light sensing unit 111d is configured to receive the light emitted by the first sub-pixel 111a reflected by the sensed object, that is, at this time, the light emitted by the second sub-pixel 111b and the third sub-pixel 111c is stray light relative to the light sensing unit 111d, which will interfere with the signal detection of the light sensing unit 111d. Exemplarily, the first sub-pixel 111a is green light, the second sub-pixel 111b is red light, and the third sub-pixel 111c is blue light.

[0104] Specifically, since the length of the first side 111d1 of the light sensing unit 111d is greater than the lengths of the other sides of the light sensing unit 111d, the length of the second side 111a1 of the first sub-pixel 111a is greater than the lengths of the other sides of the first sub-pixel 111a, and the first side 111d1 is adjacent to the second side 111a1, the light sensing unit 111d and the first sub-pixel 111a have a larger adjacent area.

[0105] It can be understood that since the first side 111d1 is adjacent to the second side 111a1, the second sub-pixel 111b and / or the third sub-pixel 111c can only be adjacent to the other side of the light sensing unit 111d, and the length of the first side 111d1 is greater than the length of the other side of the light sensing unit 111d, so that the area of ​​the second sub-pixel 111b and / or the third sub-pixel 111c adjacent to the light sensing unit 111d is smaller than the area of ​​the first sub-pixel 111a adjacent to the light sensing unit 111d.

[0106] Furthermore, since the light sensing unit 111d is configured to receive light emitted by the first sub-pixel 111a reflected by the sensed object, at this time, the interference effect of the second sub-pixel 111b and the third sub-pixel 111c on the light sensing unit 111d is smaller than the identification signal of the light sensing unit 111d detecting the first sub-pixel 111a, thereby enabling the light sensing unit 111d to maintain a high detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0107] In addition, since the embodiment of the present application only needs to arrange the position of the light sensing unit 111d relative to the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c, and does not need to add other functional structures, it can simplify the design difficulty of designers and reduce the manufacturing difficulty of production personnel, thereby facilitating the production of the display device 1.

[0108] In one embodiment, referring to Figure 3 As shown, the number of the light sensing units 111d is greater than the number of the second sub-pixels 111b, and the number of the light sensing units 111d is greater than the number of the third sub-pixels 111c.

[0109] In this way, the ability of the light sensing unit 111d to receive the light signal emitted by the first sub-pixel 111a reflected by the sensed object can be improved. At the same time, the interference of the second sub-pixel 111b and the third sub-pixel 111c to the light sensing unit 111d can be reduced, thereby improving the detection sensitivity of the light sensing unit 111d and further improving the fingerprint recognition effect of the display device 1.

[0110] In one embodiment, referring to Figure 4As shown, the number of the light sensing units 111 d is greater than or equal to the number of the first sub-pixels 111 a .

[0111] In this way, the light emitted by the first sub-pixel 111a reflected by the sensed object can be simultaneously received by multiple light sensing units 111d, which can increase the intensity of the light emitted by the first sub-pixel 111a reflected by the sensed object received by the light sensing unit 111d, thereby increasing the detection sensitivity of the light sensing unit 111d and further improving the fingerprint recognition effect of the display device 1.

[0112] In one embodiment, referring to Figure 4 , Figure 5 and Figure 6 As shown, the number of the first sub-pixels 111a is greater than or equal to the number of the second sub-pixels 111b, and the number of the first sub-pixels 111a is greater than or equal to the number of the third sub-pixels 111c.

[0113] In this way, on the one hand, the optical signal required for the light sensing unit 111d can be increased by the first sub-pixels 111a with a larger number, and accordingly, the interference of the second sub-pixels 111b and / or the third sub-pixels 111c with a smaller number on the light sensing unit 111d can be reduced, thereby improving the detection sensitivity of the light sensing unit 111d and improving the fingerprint recognition effect of the display device 1; on the other hand, the first sub-pixels 111a, the second sub-pixels 111b and the third sub-pixels 111c can be borrowed by adjacent pixels, so that the display device 1 can have a higher PPI and aperture ratio. At the same time, the display device 1 can have a better display effect and the service life of the display device 1 can be improved.

[0114] In one embodiment, referring to Figure 6 As shown, the number of the first sub-pixels 111 a is greater than or equal to the sum of the number of the second sub-pixels 111 b and the number of the third sub-pixels 111 c .

[0115] In this way, it can be understood that at this time, the number of first sub-pixels 111a must be greater than the number of second sub-pixels 111b, and greater than the number of third sub-pixels 111c. On the one hand, the detection sensitivity of the light sensing unit 111d can be better improved, and the fingerprint recognition effect of the display device 1 can be improved; on the other hand, the display device 1 can have a higher PPI and aperture ratio.

[0116] In one embodiment, the number of the second sub-pixels 111 b is equal to the number of the third sub-pixels 111 c .

[0117] In this way, the interferences of the second sub-pixel 111b and the third sub-pixel 111c on the light sensing unit 111d can be the same, and both are smaller than the light signal provided by the first sub-pixel 111a to the light sensing unit 111d, which can ensure that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a, and can enable the light sensing unit 111d to maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0118] In addition, it can ensure that the light emitted by the first subpixel 111a, the second subpixel 111b and the third subpixel 111c is relatively uniform, so that the display device 1 has a higher PPI and aperture ratio, and avoids wasting space and position on the second subpixel 111b or the third subpixel 111c.

[0119] In one embodiment, referring to Figure 3 As shown, the ratio of the number of the light sensing unit 111d, the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c is 2:1:1:1.

[0120] In this way, the pixel groups 111 can be kept at a minimum proportion, so that on the basis of improving the fingerprint recognition effect of the display device 1 , the number of pixel groups 111 in the display panel 10 is increased, thereby improving the display effect of the display device 1 .

[0121] In one embodiment, referring to Figure 4 and Figure 5 As shown, the ratio of the number of the light sensing unit 111d, the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c is 2:2:1:1.

[0122] In this way, on the one hand, by increasing the number of first sub-pixels 111a, more light signals can be provided to the light sensing unit 111d, thereby improving the detection sensitivity of the light sensing unit 111d, thereby improving the fingerprint recognition effect of the display device 1; on the other hand, by increasing the number of first sub-pixels 111a, adjacent pixels between the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c can be borrowed, so that the display device 1 has a higher PPI and aperture ratio.

[0123] In one embodiment, the ratio of the number of the light sensing unit 111d, the number of the first sub-pixel 111a, the number of the second sub-pixel 111b and the number of the third sub-pixel 111c is 3:3:2:1.

[0124] In this way, since the number of light sensing units 111d and the first sub-pixel 111a are respectively greater than the number of the second sub-pixel 111b and the third sub-pixel 111c, and are equal to the sum of the number of the second sub-pixel 111b and the third sub-pixel 111c, the light sensing unit 111d can receive the light signal more effectively through the larger number of light sensing units 111d and the first sub-pixel 111a. At the same time, the interference to the light sensing unit 111d can be reduced through the smaller number of second sub-pixels 111b and the third sub-pixel 111c. The light sensing unit 111d can maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0125] In one embodiment, referring to Figure 6 As shown, the ratio of the number of the light sensing unit 111d, the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c is 3:3:1:1.

[0126] In this way, since the number of second sub-pixels 111b is further reduced, the interference of the second sub-pixels 111b on the optical signal of the light sensing unit 111d is further reduced, so that the light sensing unit 111d can maintain a high detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0127] In one embodiment, referring to Figure 7 As shown, the ratio of the number of the light sensing unit 111d, the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c is 3:2:1:1.

[0128] In this way, although the number of first sub-pixels 111a is further reduced, the number of light sensing units 111d at this time far exceeds the number of first sub-pixels 111a, second sub-pixels 111b and third sub-pixels 111c, so that the interference of the second sub-pixel 111b and the third sub-pixel 111c on the light sensing unit 111d is relatively low. At the same time, the number of first sub-pixels 111a is still greater than the number of second sub-pixels 111b and the third sub-pixel 111c, that is, the ability of the first sub-pixel 111a to provide light signals to the light sensing unit 111d is stronger than the interference ability of the second sub-pixel 111b and the third sub-pixel 111c on the light sensing unit 111d, that is, it can be ensured that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a, which can enable the light sensing unit 111d to maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0129] In addition, by having more first sub-pixels 111a than second sub-pixels 111b and third sub-pixels 111c, adjacent sub-pixels of the first sub-pixels 111a, the second sub-pixels 111b and the third sub-pixels 111c can be borrowed, so that the display device 1 has a higher PPI and aperture ratio.

[0130] In one embodiment, referring to Figure 8 As shown, the distance between the center of the light sensing unit 111d and the center of the first sub-pixel 111a is L1, and the distance between the center of the light sensing unit 111d and the center of the second sub-pixel 111b is L2; ​​wherein L1<L2.

[0131] In this way, the area adjacent to the light sensing unit 111d and the first sub-pixel 111a is larger than the area adjacent to the light sensing unit 111d and the second sub-pixel 111b, which can ensure that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a. At the same time, it can ensure that the light sensing unit 111d can maintain a smaller receiving area with the second sub-pixel 111b, thereby reducing the interference of the second sub-pixel 111b on the light sensing unit 111d, and can enable the light sensing unit 111d to maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0132] In one embodiment, referring to Figure 8 As shown, the distance between the center of the light sensing unit 111d and the center of the third sub-pixel 111c is L3; wherein L1<L3.

[0133] In this way, the area adjacent to the light sensing unit 111d and the first sub-pixel 111a is larger than the area adjacent to the light sensing unit 111d and the third sub-pixel 111c, which can ensure that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a. At the same time, it can ensure that the light sensing unit 111d can maintain a smaller receiving area with the third sub-pixel 111c, thereby reducing the interference of the third sub-pixel 111c on the light sensing unit 111d, and can enable the light sensing unit 111d to maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0134] In one embodiment, part of the light sensing unit 111d is disposed on a side of the first sub-pixel 111a away from the second sub-pixel 111b, and part of the light sensing unit 111d is disposed on a side of the first sub-pixel 111a away from the third sub-pixel 111c.

[0135] In this way, part of the light sensing unit 111d and the second sub-pixel 111b can maintain a small receiving area, and at the same time, part of the light sensing unit 111d and the third sub-pixel 111c can maintain a small receiving area, thereby further reducing the interference of the second sub-pixel 111b and the third sub-pixel 111c on the light sensing unit 111d, and maintaining a high detection sensitivity of the light sensing unit 111d, thereby improving the fingerprint recognition effect of the display device 1.

[0136] In one embodiment, some light sensing units 111d are disposed on a side of the first sub-pixel 111a away from the second sub-pixel 111b, and the remaining light sensing units 111d are disposed on a side of the first sub-pixel 111a away from the third sub-pixel 111c.

[0137] In this way, part of the light sensing unit 111d and the second sub-pixel 111b can maintain a small receiving area, while the remaining light sensing units 111d and the third sub-pixel 111c can maintain a small receiving area, so that the interference of the second sub-pixel 111b and the third sub-pixel 111c to the light sensing unit 111d can be minimized, and the light sensing unit 111d can maintain a high detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0138] In one embodiment, the light sensing units 111d and the first sub-pixels 111a are arranged in pairs in a one-to-one correspondence. In the paired light sensing units 111d and the first sub-pixels 111a, the light sensing units 111d and the first sub-pixels 111a are arranged at intervals along the first direction.

[0139] It should be noted that the first direction is Figure 4 , Fig. 9 The X direction in the second direction is Figure 4 , Fig. 9 in the Y direction.

[0140] In this way, the light sensing unit 111d and the first sub-pixel 111a are arranged in pairs, so that the light signal received by the light sensing unit 111d can be improved, and the ability of the light sensing unit 111d to receive the light signal emitted by the first sub-pixel 111a reflected by the sensed object can be improved, thereby improving the detection sensitivity of the light sensing unit 111d and further improving the fingerprint recognition effect of the display device 1.

[0141] In one embodiment, along the first direction, the second sub-pixel 111 b is disposed on a side of the pair of first sub-pixels 111 a away from the light sensing unit 111 d .

[0142] Thus, the area adjacent to the light sensing unit 111d and the first sub-pixel 111a is larger than the area adjacent to the light sensing unit 111d and the second sub-pixel 111b, so that the light sensing unit 111d can maintain a high detection sensitivity and improve the fingerprint recognition effect of the display device 1.

[0143] In one embodiment, referring to Figure 4 and Figure 5 As shown, along the first direction, the third sub-pixel 111c is disposed on a side of the other pair of first sub-pixels 111a away from the light sensing unit 111d.

[0144] Thus, the area adjacent to the light sensing unit 111d and the first sub-pixel 111a is larger than the area adjacent to the light sensing unit 111d and the third sub-pixel 111c, so that the light sensing unit 111d can maintain a high detection sensitivity and improve the fingerprint recognition effect of the display device 1.

[0145] In one embodiment, referring to Figure 4 and Figure 5 As shown, along the second direction, the second sub-pixel 111b is adjacent to the third sub-pixel 111c; wherein the first direction intersects the second direction.

[0146] In this way, on the one hand, the area adjacent to the light sensing unit 111d and the first sub-pixel 111a is larger than the area adjacent to the light sensing unit 111d and the second sub-pixel 111b and the third sub-pixel 111c, so that the light sensing unit 111d can maintain a high detection sensitivity, and the fingerprint recognition effect of the display device 1 can be improved; on the other hand, the second sub-pixel 111b and the third sub-pixel 111c are adjacent, and both are adjacent to the first sub-pixel 111a, which is conducive to the mixing of light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c, thereby improving the display effect of the display device 1.

[0147] In one embodiment, the first direction is perpendicular to the second direction.

[0148] In this way, the first sub-pixel 111a, the second sub-pixel 111b, the third sub-pixel 111c and the light sensing unit 111d can be arranged evenly, and within a single pixel group 111, the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c is relatively uniform, which is beneficial to the mixing of the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c, thereby improving the display effect of the display device 1.

[0149] In one embodiment, referring to Figure 4 and Figure 5As shown, the number of light sensing units 111d and the number of first sub-pixels 111a are both two, and the number of second sub-pixels 111b and third sub-pixels 111c are both one; along the first direction, the second sub-pixel 111b is arranged on a side of one pair of first sub-pixels 111a away from the light sensing unit 111d, and the third sub-pixel 111c is arranged on a side of the other pair of first sub-pixels 111a away from the light sensing unit 111d, and along the second direction, the second sub-pixel 111b and the third sub-pixel 111c are adjacent.

[0150] In this way, similarly, on the one hand, the light sensing unit 111d can maintain a high detection sensitivity, which can improve the fingerprint recognition effect of the display device 1; on the other hand, it is beneficial to mix the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c, thereby improving the display effect of the display device 1.

[0151] In one embodiment, referring to Fig. 9 As shown, at least one first sub-pixel 111a, at least one second sub-pixel 111b, at least one third sub-pixel 111c and a plurality of light sensing units 111d are arranged in columns along a first direction and in rows along a second direction intersecting the first direction.

[0152] In this way, the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c can be located in different rows and columns, and the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c can be better mixed, thereby improving the display effect of the display device 1. In addition, the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c can be borrowed by adjacent pixels, so that the display device 1 can have a higher PPI and aperture ratio.

[0153] In one embodiment, referring to Fig. 9 As shown, at least one first sub-pixel 111a, at least one second sub-pixel 111b, at least one third sub-pixel 111c and a plurality of light sensing units 111d are arranged in M ​​columns along a first direction and in N rows along a second direction intersecting the first direction; wherein N=M+1, or N=M-1.

[0154] In this way, based on the above description, it can be ensured that the length and width of the rows and columns of the pixel group 111 are similar, so that the distance between the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c is not too far apart, which is beneficial to the mixing of the light emitted by the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c, thereby improving the display effect of the display device 1.

[0155] In one embodiment, referring to Fig. 9 As shown, N=M.

[0156] In this way, the length and width of the rows and columns of the pixel group 111 can be ensured to be the same, which is more conducive to mixing the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c, thereby further improving the display effect of the display device 1.

[0157] In one embodiment, the first direction is perpendicular to the second direction.

[0158] In this way, the first sub-pixel 111a, the second sub-pixel 111b, the third sub-pixel 111c and the light sensing unit 111d can be arranged evenly, and within the single pixel group 111, it is beneficial to mix the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c, thereby improving the display effect of the display device 1.

[0159] In one embodiment, referring to Fig.10 As shown, the first direction and the second direction are inclined.

[0160] It should be noted that the first direction is Fig.10 The second direction is Fig.10 in the Y direction.

[0161] In this way, when multiple pixel groups 111 are arranged to form a display panel 10, the pixel group 111 located on the side of the display panel 10 must be inclined to the side of the display panel 10. At this time, another partial pixel group 111 can be set in the space where the pixel group 111 is inclined to the side of the display panel 10, so that the display device 1 can have a higher PPI and aperture ratio by borrowing sub-pixels in the partial pixel group 111.

[0162] In one embodiment, a line connecting the center of the first sub-pixel 111 a and the center of the second sub-pixel 111 b is collinear with the first direction.

[0163] In this way, the positions of the first sub-pixel 111a and the second sub-pixel 111b can be arranged evenly, and the positions of the first sub-pixel 111a and the second sub-pixel 111b are close to each other, which is conducive to mixing the light emitted by the first sub-pixel 111a and the second sub-pixel 111b, and can improve the display effect of the display device 1.

[0164] In one embodiment, the center of the light sensing unit 111 d , the center of the first sub-pixel 111 a , and the center of the second sub-pixel 111 b are collinear.

[0165] In this way, the positions of the first sub-pixel 111a and the third sub-pixel 111c can be arranged evenly, and the positions of the first sub-pixel 111a and the third sub-pixel 111c are close to each other, which is beneficial to the mixing of the light emitted by the first sub-pixel 111a and the third sub-pixel 111c, and the display effect of the display device 1 can be improved.

[0166] In one embodiment, the light sensing unit 111d and the first sub-pixel 111a are arranged in pairs in a one-to-one correspondence; a line connecting the centers of a pair of light sensing units 111d, the centers of the first sub-pixel 111a, and the centers of the second sub-pixel 111b is inclined to the second direction; a line connecting the centers of a pair of light sensing units 111d, the centers of the first sub-pixel 111a, and the centers of the third sub-pixel 111c is inclined to the second direction.

[0167] In this way, the positions of the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c can be arranged evenly, and the positions of the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c are close to each other, which is beneficial to the mixing of the light emitted by the first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c, and can improve the display effect of the display device 1.

[0168] In one embodiment, the angle between the line connecting the center of any pair of light sensing units 111 d and the center of the first sub-pixel 111 a and the second direction is 135°.

[0169] In this way, the borrowing of sub-pixels between one pixel group 111 and an adjacent pixel group 111 can be maximized, and the PPI and aperture ratio of the display device 1 can be maximized.

[0170] In one embodiment, the angle between the center of the first sub-pixel 111 a and the center of the second sub-pixel 111 b and the second direction is 135°.

[0171] In this way, similarly, the borrowing of sub-pixels between one pixel group 111 and an adjacent pixel group 111 can be maximized, and the PPI and aperture ratio of the display device 1 can be maximized.

[0172] In one embodiment, the light sensing unit 111d further includes a third side 111d2 , and the length of the first side 111d1 is greater than the length of the third side 111d2 ; the third side 111d2 is adjacent to the second sub-pixel 111b and / or the third sub-pixel 111c .

[0173] In this way, the light sensing unit 111d can have a larger adjacent area with the first sub-pixel 111a, and a smaller adjacent area with the second sub-pixel 111b and / or the third sub-pixel 111c, which can ensure that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a, and can enable the light sensing unit 111d to maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0174] In one embodiment, the area of ​​the light sensing unit 111 d adjacent to the first sub-pixel 111 a is A; the area of ​​the light sensing unit 111 d adjacent to the second sub-pixel 111 b is B; wherein A>B.

[0175] In this way, it can be ensured that the area adjacent to the first sub-pixel 111a of the light sensing unit 111d is larger than the area adjacent to the second sub-pixel 111b, and it can be ensured that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a, and at the same time, the interference of the second sub-pixel 111b to the light sensing unit 111d can be reduced, so that the light sensing unit 111d can maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0176] In one embodiment, the area adjacent to the light sensing unit 111 d and the third sub-pixel 111 c is C; wherein A>C.

[0177] In this way, it can be ensured that the area adjacent to the first sub-pixel 111a of the light sensing unit 111d is larger than the area adjacent to the third sub-pixel 111c, and it can be ensured that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a, and at the same time, the interference of the third sub-pixel 111c to the light sensing unit 111d can be reduced, so that the light sensing unit 111d can maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0178] In one embodiment, a vertical distance between the first side 111d1 and the center of the first sub-pixel 111a is smaller than a vertical distance between the second side 111a1 and the center of the second sub-pixel 111b or the third sub-pixel 111c.

[0179] In this way, the adjacent area of ​​the light sensing unit 111d and the second sub-pixel 111b or the third sub-pixel 111c can be further reduced, thereby further reducing the interference of the second sub-pixel 111b or the third sub-pixel 111c on the light sensing unit 111d, and further enabling the light sensing unit 111d to maintain a high detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0180] In one embodiment, along the first direction, the light sensing unit 111d and the second sub-pixel 111b are respectively disposed on two sides of the first sub-pixel 111a.

[0181] In this way, along the first direction, the light sensing unit 111d and the second sub-pixel 111b have no adjacent area, and the light sensing unit 111d can only be adjacent to part of the side of the second sub-pixel 111b in other directions, thereby further reducing the interference of the second sub-pixel 111b on the light sensing unit 111d, thereby enabling the light sensing unit 111d to maintain a high detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0182] In one embodiment, the third sub-pixel 111 c is disposed on a side of the first sub-pixel 111 a away from the light sensing unit 111 d .

[0183] In this way, along the first direction, the light sensing unit 111d and the third sub-pixel 111c have no adjacent areas, and the light sensing unit 111d can only be adjacent to part of the side of the third sub-pixel 111c in other directions, thereby further reducing the interference of the third sub-pixel 111c on the light sensing unit 111d, thereby enabling the light sensing unit 111d to maintain a high detection sensitivity, and ultimately improving the fingerprint recognition effect of the display device 1.

[0184] In one embodiment, the third side 111d2 is collinear with the first direction, and the first side 111d1 is collinear with the second direction; wherein the first direction intersects with the second direction.

[0185] In this way, since the light sensing unit 111d and the first sub-pixel 111a are arranged at intervals along the first direction, the length of the first side 111d1 is greater than the length of the third side 111d2, thereby ensuring that the area adjacent to the light sensing unit 111d and the first sub-pixel 111a is greater than the area adjacent to the second sub-pixel 111b and / or the third sub-pixel 111c, and ensuring that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a, and at the same time reducing the interference of the second sub-pixel 111b and / or the third sub-pixel 111c to the light sensing unit 111d, so that the light sensing unit 111d can maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0186] In one embodiment, the first direction is perpendicular to the second direction.

[0187] In this way, the first sub-pixel 111a, the second sub-pixel 111b, the third sub-pixel 111c and the light sensing unit 111d can be arranged evenly, and within a single pixel group 111, the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c is relatively uniform, which is beneficial to the mixing of the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c, thereby improving the display effect of the display device 1.

[0188] In one embodiment, referring to Figure 4 , Figure 6 and Fig.10 As shown, the shape of the light sensing unit 111d is the same as that of the first sub-pixel 111a.

[0189] In this way, on the one hand, a larger adjacent area can be provided between the light sensing unit 111d and the first sub-pixel 111a, thereby increasing the optical signal provided by the first sub-pixel 111a to the light sensing unit 111d, and ultimately improving the fingerprint recognition effect of the display device 1; on the other hand, the light sensing unit 111d and the first sub-pixel 111a can share the FMM, which can reduce the mold opening cost and save the FMM mold opening fee.

[0190] In one embodiment, referring to Fig.11 As shown, the light sensing unit 111d is in an octagonal shape.

[0191] In this way, part of the side edges of the light sensing unit 111d can maintain a larger adjacent area with the first sub-pixel 111a, part of the side edges can maintain a smaller adjacent area with the second sub-pixel 111b, and part of the side edges can maintain a smaller adjacent area with the third sub-pixel 111c, thereby ensuring that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a. At the same time, it can be ensured that the light sensing unit 111d can maintain a smaller receiving area with the third sub-pixel 111c, thereby reducing the interference of the third sub-pixel 111c on the light sensing unit 111d, and enabling the light sensing unit 111d to maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0192] In one embodiment, referring to Fig.11 As shown, the shape of the second sub-pixel 111b is a polygon, a triangle or a sector.

[0193] In this way, part of the side of the second sub-pixel 111b can have a larger adjacent area with the first sub-pixel 111a, part of the side can have a larger adjacent area with the third sub-pixel 111c, and part of the side can have a smaller adjacent area with the light sensing unit 111d. On the one hand, the interference with the light sensing unit 111d can be reduced, so that the light sensing unit 111d maintains a higher detection sensitivity; on the other hand, it is conducive to the mixing of the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c, thereby improving the display effect of the display device 1. In addition, the influence of the lateral light crosstalk and leakage of the second sub-pixel 111b and the third sub-pixel 111c on the signal detection of the light sensing unit 111d can also be reduced.

[0194] In one embodiment, referring to Fig.11 As shown, the shape of the second sub-pixel 111b is circular.

[0195] In this way, the area adjacent to the second sub-pixel 111b and the light sensing unit 111d can be further reduced, thereby further reducing the interference of the second sub-pixel 111b on the light sensing unit 111d, thereby further improving the detection sensitivity of the light sensing unit 111d.

[0196] In one embodiment, the third sub-pixel 111 c is in a polygonal, triangular or fan-shaped shape.

[0197] In this way, part of the side of the third sub-pixel 111c can have a larger adjacent area with the first sub-pixel 111a, part of the side can have a larger adjacent area with the second sub-pixel 111b, and part of the side can have a smaller adjacent area with the light sensing unit 111d. On the one hand, the interference with the light sensing unit 111d can be reduced, so that the light sensing unit 111d maintains a high detection sensitivity; on the other hand, it is conducive to the mixing of the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c, thereby improving the display effect of the display device 1. In addition, the influence of the lateral light crosstalk and leakage of the second sub-pixel 111b and the third sub-pixel 111c on the signal detection of the light sensing unit 111d can also be reduced.

[0198] In one embodiment, the third sub-pixel 111 c is circular in shape.

[0199] In this way, the area adjacent to the third sub-pixel 111c and the light sensing unit 111d can be further reduced, thereby further reducing the interference of the third sub-pixel 111c on the light sensing unit 111d, thereby further improving the detection sensitivity of the light sensing unit 111d.

[0200] In one embodiment, the plurality of pixel groups 111 are arranged in columns along a first direction, and are arranged in rows along a second direction intersecting the first direction.

[0201] In this way, through the joint action of multiple pixel groups 111, on the one hand, it is beneficial to mix the light emitted by the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c, thereby improving the display effect of the display device 1; on the other hand, it can improve the detection sensitivity of the light sensing unit 111d, thereby improving the fingerprint recognition effect of the display device 1.

[0202] In one embodiment, in any two adjacent pixel groups 111, a second sub-pixel 111b in one pixel group 111 is adjacent to a light sensing unit 111d in another pixel group 111, and a third sub-pixel 111c in the pixel group 111 is adjacent to another light sensing unit 111d in the other pixel group 111.

[0203] In this way, the different first sub-pixels 111a, second sub-pixels 111b and third sub-pixels 111c of two adjacent pixel groups 111 can borrow sub-pixels between adjacent pixel groups 111, thereby further improving the PPI and aperture ratio of the display device 1.

[0204] In one embodiment, the first direction is perpendicular to the second direction.

[0205] In this way, the sub-pixels in the same pixel group 111 and the sub-pixels in different pixel groups 111 can be arranged evenly, thereby improving the display effect of the display device 1 .

[0206] Second, refer to Fig.12 As shown, an embodiment of the present application provides a display panel 10, and the display panel 10 includes the pixel arrangement structure 11 in the first aspect.

[0207] The display panel 10 provided by the embodiment of the present application is provided with a first sub-pixel 111a, a second sub-pixel 111b, a third sub-pixel 111c and a light sensing unit 111d. The first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c are respectively used to emit light of different colors; the light sensing unit 111d is configured to receive the light emitted by the first sub-pixel 111a reflected by the sensed object, and the first side 111d1 of the light sensing unit 111d is adjacent to the second side 111a1 of the first sub-pixel 111a. In this way, the first side 111d1 and the second side 111a1 can be adjacent to each other, so that the light sensing unit 111d and the first sub-pixel 111a have a larger adjacent area, so that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a, and the light sensing unit 111d can maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0208] In one embodiment, referring to Fig.13 As shown, the display panel 10 further includes a substrate 12 and an isolation structure 13. The isolation structure 13 is disposed on the substrate 12; the isolation structure 13 has a plurality of isolation opening groups 13a; the plurality of isolation opening groups 13a are arranged in columns along a first direction and arranged in rows along a second direction intersecting the first direction; each isolation opening group 13a includes a first opening 13a1, a second opening 13a2, and a third opening 13a3 that are arranged at intervals, the first sub-pixel 111a is disposed in the first opening 13a1, the second sub-pixel 111b is disposed in the second opening 13a2, and the third sub-pixel 111c is disposed in the third opening 13a3.

[0209] It should be noted that the isolation structure 13 refers to a structure that can isolate the light-emitting materials of adjacent sub-pixels when the pixel material of the sub-pixel is evaporated. By setting the isolation structure 13, a graphic lithography process can be used for the sub-pixels, thereby eliminating FMM, which is beneficial to improve PPI. Furthermore, since the sub-pixels are made by a graphic lithography process, compared with the display panel 10 that uses FMM to evaporate the sub-pixels, the embodiment of the present application can make the sub-pixels richer in shape and more optimized in arrangement, which can overcome the display shortcomings in the related art to further improve the display effect.

[0210] In addition, the isolation structure 13 can reduce the influence of leakage current and lateral optical crosstalk on the light sensing unit 111 d without adding additional process steps.

[0211] In one embodiment, the first sub-pixel 111 a , the second sub-pixel 111 b , and the third sub-pixel 111 c each include a first electrode 1111 , a light emitting functional portion 1112 , and a second electrode 1113 which are stacked.

[0212] Thus, the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c all include a first electrode 1111, a light-emitting functional portion 1112, and a second electrode 1113 that are stacked. The second electrodes 1113 of at least a portion of the first sub-pixel 111a, the second sub-pixel 111b, and the third sub-pixel 111c are electrically connected to the isolation structure 13. In this way, it is convenient to connect the second electrodes 1113 of the sub-pixels to the pixel driving circuit through the isolation structure 13, thereby optimizing the wiring arrangement of the display area.

[0213] In a preferred embodiment, in the first sub-pixel 111 a , the second sub-pixel 111 b , and the third sub-pixel 111 c , the second electrodes 1113 of at least a portion of the sub-pixels are electrically connected to the isolation structure 13 .

[0214] It should be noted that the first electrode 1111 may be an anode, and the second electrode 1113 may be a cathode. The first electrode 1111 and the second electrode 1113 are both electrically connected to the pixel driving circuit. If the first electrode 1111 is a cathode, the isolation structure 13 transmits a VSS signal, and if the first electrode 1111 is an anode, the isolation structure 13 transmits a VDD signal.

[0215] The light-emitting functional part 1112 includes at least a light-emitting layer (Emission layer, EML), and may also include one or more of a hole injection layer (HIL), a hole transport layer (HTL), an electron injection layer (EIL), an electron transport layer (ETL), a hole blocking layer (HBL) and an electron blocking layer (EBL). Alternatively, the light-emitting functional part 1112 may also be a stacked light-emitting structure, that is, including at least two light-emitting layers and a charge generation layer (CGL) located between each adjacent light-emitting layer.

[0216] In one embodiment, the isolation structure 13 includes a conductive portion 131 and a blocking portion 132 stacked in a direction away from the substrate 12, and an end of the blocking portion 132 close to the sub-pixel extends toward the opening corresponding to the sub-pixel to protrude from the surface of the conductive portion 131 close to the sub-pixel. The second electrode 1113 is electrically connected to the conductive portion 131.

[0217] In this way, the isolation structure 13 can have both a "partitioning" function and a conductive function.

[0218] In one embodiment, the conductive part 131 includes at least one metal layer. In one example, the material of the conductive part 131 includes at least one of a metal and a metal oxide. Exemplarily, the metal may be silver, copper, titanium, aluminum, etc. The metal oxide may be tin oxide, zinc oxide, cadmium oxide, indium oxide, indium tin oxide, zinc indium oxide, zinc gallium oxide, zinc aluminum oxide, titanium tantalum oxide, etc.

[0219] In one embodiment, the isolation structure 13 further includes a supporting portion 133 , and the supporting portion 133 is disposed between the substrate 12 and the conductive portion 131 .

[0220] In one example, the carrier portion 133 includes a conductive material, which is beneficial to reduce the resistance of the isolation structure 13 and thus reduce the power consumption of the display panel 10 .

[0221] In one embodiment, the display panel 10 further includes a pixel defining layer 14 , which is disposed between the substrate 12 and the isolation structure 13 . The pixel defining layer 14 defines a pixel opening, which corresponds to the isolation opening.

[0222] Thirdly, refer to Fig.14 As shown, an embodiment of the present application provides a display device 1, which includes the display panel 10 in the second aspect.

[0223] The display device 1 provided by the embodiment of the present application is provided with a first sub-pixel 111a, a second sub-pixel 111b, a third sub-pixel 111c and a light sensing unit 111d. The first sub-pixel 111a, the second sub-pixel 111b and the third sub-pixel 111c are respectively used to emit light of different colors; the light sensing unit 111d is configured to receive the light emitted by the first sub-pixel 111a reflected by the sensed object, and the first side 111d1 of the light sensing unit 111d is adjacent to the second side 111a1 of the first sub-pixel 111a. In this way, the first side 111d1 and the second side 111a1 can be adjacent to each other, so that the light sensing unit 111d and the first sub-pixel 111a have a larger adjacent area, so that the light sensing unit 111d can maintain a larger receiving area within a smaller angle range, thereby identifying the light signal reflected by the first sub-pixel 111a, and the light sensing unit 111d can maintain a higher detection sensitivity, thereby improving the fingerprint recognition effect of the display device 1.

[0224] 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 TV 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.

To make the description concise, not all possible combinations of the technical features in the above 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.
