[0062] 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.

These terms are only used to distinguish one element from another element.

[0064] 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.

[0065] 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.

[0066] 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 that the finger reflects the light emitted by the OLED light-emitting unit to the OPD unit, and the OPD unit converts the light signal into an electrical signal, thereby realizing the recognition of the user's fingerprint information. However, the current OLED display panel has the problem of poor display effect and fingerprint recognition effect.

[0067] 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, by making the number ratio of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the light sensing unit in the pixel group 2:1:1:1, and making the light sensing unit adjacent to at least one first sub-pixel. In this way, on the one hand, it is conducive to making the sub-pixels in the pixel group satisfy the pixel borrowing relationship, and a high PPI can be achieved through the pixel borrowing relationship, thereby improving the display effect; on the other hand, it is conducive to increasing the number of preset wavelengths of light reflected by the sensed object (the light emitted by the first sub-pixel), so that the light sensing unit can receive more preset wavelengths of light, thereby improving the fingerprint recognition sensitivity.

[0068] For a better understanding, some explanations are given before going into detail:

[0069] 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.

[0070] 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.

[0071] 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.

[0072] Sub-pixel rendering technology: Sub-pixel rendering (SPR) technology can use the difference in the human eye's resolution of sub-pixels of different colors to change the conventional red, green, and blue sub-pixels that simply define a pixel mode. By sharing certain sub-pixels of resolution-insensitive colors between different pixel groups, relatively fewer sub-pixels can be used to simulate the same pixel resolution performance.

[0073] First, refer to Figure 1 and Figure 2 As shown, the embodiment of the present application provides a pixel arrangement structure 11, which includes a plurality of pixel groups 11a, each pixel group 11a includes a first sub-pixel 111, a second sub-pixel 112, a third sub-pixel 113 and a light sensing unit 114. In the same pixel group 11a, the ratio of the number of the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113 and the light sensing unit 114 is 2:1:1:1.

[0074] The first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 are respectively used to emit light of different colors, and the light sensing unit 114 is configured to receive the light emitted by the first sub-pixel 111 reflected by the sensed object. Exemplarily, the light sensing unit 114 may be an OPD (Organic Photodiode), and the sensed object may be a user's finger.

[0075] In the same pixel group 11 a , the light sensing unit 114 is disposed adjacent to at least one first sub-pixel 111 .

[0076] It should be noted that "the light sensing unit 114 is arranged adjacent to the first sub-pixel 111" means: there are no other sub-pixels between the light sensing unit 114 and the first sub-pixel 111, and the two are directly adjacent. The pixel group 11a refers to: the smallest repeating unit repeatedly arranged in the pixel arrangement structure 11. The first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 can 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 can also be sub-pixels that emit 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.

[0077] In a specific embodiment, the first sub-pixel 111 emits green light, the second sub-pixel 112 emits red light, and the third sub-pixel 113 emits blue light.

[0078] The pixel arrangement structure 11 provided in the embodiment of the present application makes the number ratio of the first sub-pixel 111, the second sub-pixel 112, the third sub-pixel 113 and the light sensing unit 114 in the pixel group 11a to be 2:1:1:1, and the light sensing unit 114 is arranged adjacent to at least one first sub-pixel 111. In this way, on the one hand, the SPR (Sub-pixel Rendering) algorithm can be applied to realize the borrowing between adjacent sub-pixels, and a high PPI can be achieved through the pixel borrowing relationship to improve the display effect. Further, referring to Figure 3 As shown, Figure 3 for Figure 1 A schematic diagram of pixel borrowing in the pixel arrangement structure 11 shown; on the other hand, the distance between the light sensing unit 114 and the first sub-pixel 111 can be made closer, which is beneficial to increase the amount of light of a preset wavelength reflected by the sensed object (the light emitted by the first sub-pixel 111), thereby making the light sensing unit 114 receive a larger amount of light of a preset wavelength, thereby improving the fingerprint recognition sensitivity.

[0079] In one embodiment, referring to Figure 2 As shown, in the same pixel group 11a, the light sensing unit 114 is disposed adjacent to a plurality of first sub-pixels 111. In this way, the number of first sub-pixels 111 near the light sensing unit 114 can be increased, which is beneficial to increase the number of light rays of a preset wavelength reflected by the sensed object (light rays emitted by the first sub-pixels 111), thereby increasing the number of light rays of a preset wavelength received by the light sensing unit 114, thereby improving the fingerprint recognition sensitivity.

[0080] In a preferred embodiment, referring to Figure 2 As shown, in the same pixel group 11 a , the light sensing unit 114 is disposed adjacent to all the first sub-pixels 111 .

[0081] In one embodiment, in combination Figure 1 and Figure 2 As shown, in two adjacent pixel groups 11a, the light sensing unit 114 in one pixel group 11a is arranged adjacent to a first sub-pixel 111 in the other pixel group 11a. In this way, the number of first sub-pixels 111 near the light sensing unit 114 can be increased, which is beneficial to increase the number of light rays of a preset wavelength reflected by the sensed object (light rays emitted by the first sub-pixel 111), and further the number of light rays of a preset wavelength received by the light sensing unit 114 can be increased, thereby improving the fingerprint recognition sensitivity.

[0082] In one embodiment, the pixel group 11a includes two first sub-pixels 111, a second sub-pixel 112, a third sub-pixel 113 and a light sensing unit 114. In this way, the SPR (Sub-pixel Rendering) algorithm can be applied to achieve borrowing between adjacent sub-pixels, and a high PPI can be achieved through the pixel borrowing relationship to improve the display effect.

[0083] In one embodiment, in combination Figure 1 and Figure 2 As shown, in the same pixel group 11a, the light sensing unit 114 is disposed adjacent to the two first sub-pixels 111. In this way, the number of first sub-pixels 111 near the light sensing unit 114 can be increased, which is beneficial to increase the number of light rays of a preset wavelength reflected by the sensed object (light rays emitted by the first sub-pixels 111), and further the number of light rays of a preset wavelength received by the light sensing unit 114 can be increased, thereby improving the fingerprint recognition sensitivity.

[0084] In one embodiment, in the same pixel group 11a, the second sub-pixel 112 is disposed adjacent to the two first sub-pixels 111. This is beneficial to the borrowing between sub-pixels, so that a high PPI can be achieved through the pixel borrowing relationship, thereby improving the display effect.

[0085] In one embodiment, in the same pixel group 11a, the third sub-pixel 113 is disposed adjacent to a first sub-pixel 111. This is beneficial to the borrowing between sub-pixels, so that a high PPI can be achieved through the pixel borrowing relationship, thereby improving the display effect. It is understandable that in the same pixel group 11a, the third sub-pixel 113 is not adjacent to another first sub-pixel 111.

[0086] In one embodiment, the plurality of pixel groups 11 a are arranged in rows along a first direction X, and in columns along a second direction Y intersecting the first direction X.

[0087] In a preferred embodiment, the first direction X and the second direction Y are perpendicular to each other.

[0088] In one embodiment, the first direction X intersects with the long side of the display panel 10 , and the second direction Y intersects with the long side of the display panel 10 .

[0089] In one embodiment, the angle between the first direction X and the long side of the display panel 10 is 45°, and the angle between the second direction Y and the long side of the display panel 10 is 45°.

[0090] In one embodiment, referring to Figure 2As shown, in the same pixel group 11a, one first sub-pixel 111 is disposed on one side of the second sub-pixel 112 along the first direction X, and another first sub-pixel 111 is disposed on one side of the second sub-pixel 112 along the second direction Y. This is beneficial to borrowing between sub-pixels, so that a high PPI can be achieved through the pixel borrowing relationship, thereby improving the display effect.

[0091] In one embodiment, in the same pixel group 11a, one first sub-pixel 111 is disposed on one side of the third sub-pixel 113 along the first direction X, and another first sub-pixel 111 is disposed on one side of the third sub-pixel 113 along the second direction Y. This is beneficial to borrowing between sub-pixels, so that a high PPI can be achieved through the pixel borrowing relationship, thereby improving the display effect.

[0092] In one embodiment, in the same pixel group 11a, the light sensing unit 114 is disposed on one side of a first sub-pixel 111 along the first direction X, and is disposed on one side of another first sub-pixel 111 along the second direction Y. In this way, on the one hand, the light sensing unit 114 can receive more light of a preset wavelength, thereby improving the fingerprint recognition sensitivity; on the other hand, the light sensing unit 114 and the light-emitting sub-pixels in the pixel group 11a can be arranged more regularly, thereby minimizing the adverse effects of the light sensing unit 114 on the display effect.

[0093] In one embodiment, in the same pixel group 11a, the second sub-pixel 112, the third sub-pixel 113, and the one first sub-pixel 111 are arranged alternately along the second direction Y, and the second sub-pixel 112 is disposed between the third sub-pixel 113 and the one first sub-pixel 111. Another first sub-pixel 111 is disposed on one side of the second sub-pixel 112 along the first direction X, and is disposed on one side of the third sub-pixel 113 along the first direction X.

[0094] Please refer to Figure 2 and Figure 3 As shown, the above arrangement is conducive to borrowing between sub-pixels, so that a high PPI can be achieved through the pixel borrowing relationship, thereby improving the display effect.

[0095] In one embodiment, referring to Figure 1 and Figure 2 As shown, in two adjacent pixel groups 11a along the first direction X, the first sub-pixel 111 in one pixel group 11a is arranged adjacent to the second sub-pixel 112 and the third sub-pixel 113 in the other pixel group 11a. Specifically, in two adjacent pixel groups 11a, the first sub-pixel 111 in the pixel group 11a located at the lower left is arranged adjacent to the second sub-pixel 112 and the third sub-pixel 113 in the pixel group 11a located at the upper right.

[0096] This is beneficial to borrowing between sub-pixels, so that a high PPI can be achieved through the pixel borrowing relationship, thereby improving the display effect.

[0097] In one embodiment, referring to Figure 1 and Figure 2 As shown, in two adjacent pixel groups 11a along the first direction X, the light sensing unit 114 in one pixel group 11a is disposed adjacent to the first sub-pixel 111 in the other pixel group 11a. Specifically, in two adjacent pixel groups 11a, the light sensing unit 114 in the pixel group 11a located at the lower left is disposed adjacent to the first sub-pixel 111 in the pixel group 11a located at the upper right.

[0098] In this way, the number of first sub-pixels 111 near the light sensing unit 114 can be increased, which is beneficial to increasing the amount of light of a preset wavelength reflected by the sensed object (the light emitted by the first sub-pixel 111), and further the amount of light of a preset wavelength received by the light sensing unit 114 can be increased, thereby improving the fingerprint recognition sensitivity.

[0099] In one embodiment, referring to Figure 1 and Figure 2 As shown, in two adjacent pixel groups 11a along the second direction Y, the first sub-pixel 111 in one pixel group 11a is disposed adjacent to the light sensing unit 114 in the other pixel group 11a. Specifically, in two adjacent pixel groups 11a, the light sensing unit 114 in the pixel group 11a located at the lower right is disposed adjacent to the first sub-pixel 111 in the pixel group 11a located at the upper left.

[0100] In this way, the number of first sub-pixels 111 near the light sensing unit 114 can be increased, which is beneficial to increasing the amount of light of a preset wavelength reflected by the sensed object (the light emitted by the first sub-pixel 111), and further the amount of light of a preset wavelength received by the light sensing unit 114 can be increased, thereby improving the fingerprint recognition sensitivity.

[0101] In one embodiment, in two adjacent pixel groups 11a along the second direction Y, the first sub-pixel 111 in one pixel group 11a is disposed adjacent to the third sub-pixel 113 in the other pixel group 11a. Specifically, in two adjacent pixel groups 11a, the first sub-pixel 111 in the pixel group 11a located at the lower right is disposed adjacent to the third sub-pixel 113 in the pixel group 11a located at the upper left.

[0102] In one embodiment, referring to Figure 1 and Figure 4As shown, in all pixel groups 11a, first sub-pixels 111 are provided on both sides of the light sensing unit 114 along the first direction X, and on both sides of the light sensing unit 114 along the second direction Y. Thus, first sub-pixels 111 are provided on four directions of the light sensing unit 114, that is, the light sensing unit 114 is surrounded by first sub-pixels 111 of the same color.

[0103] In this way, on the one hand, the consistency of the signal around the light sensing unit 114 can be ensured, and the interference of stray light emitted by other color sub-pixels on the signal detection of the light sensing unit 114 can be reduced; on the other hand, the number of first sub-pixels 111 near the light sensing unit 114 can be increased, which is beneficial to increase the number of preset wavelengths of light reflected by the sensed object (light emitted by the first sub-pixels 111), thereby increasing the number of preset wavelengths of light received by the light sensing unit 114, thereby improving the fingerprint recognition sensitivity.

[0104] In one embodiment, referring to Figure 5 and Figure 6 As shown, in the same pixel group 11a, the light sensing unit 114, the third sub-pixel 113 and one first sub-pixel 111 are arranged at intervals along the second direction Y, and the light sensing unit 114 is arranged between the third sub-pixel 113 and the one first sub-pixel 111; another first sub-pixel 111 is arranged on one side of the light sensing unit 114 along the first direction X, and is arranged on one side of the third sub-pixel 113 along the first direction X.

[0105] In this way, on the one hand, it is beneficial to borrow between sub-pixels, so that a high PPI can be achieved through the pixel borrowing relationship, thereby improving the display effect; on the other hand, the number of first sub-pixels 111 near the light sensing unit 114 can be increased, which is beneficial to increase the number of preset wavelengths of light reflected by the sensed object (light emitted by the first sub-pixel 111), thereby increasing the number of preset wavelengths of light received by the light sensing unit 114, thereby improving the fingerprint recognition sensitivity.

[0106] In one embodiment, the second sub-pixel 112 is disposed on one side of a first sub-pixel 111 along the first direction X, and is disposed on one side of another first sub-pixel 111 along the second direction Y.

[0107] This is beneficial to borrowing between sub-pixels, so that a high PPI can be achieved through the pixel borrowing relationship, thereby improving the display effect.

[0108] In one embodiment, referring to Figure 5 and Figure 6As shown, in two adjacent pixel groups 11a along the first direction X, the first sub-pixel 111 in one pixel group 11a is disposed adjacent to the light sensing unit 114 in the other pixel group 11a. Specifically, in two adjacent pixel groups 11a, the first sub-pixel 111 in the pixel group 11a located at the lower left is disposed adjacent to the light sensing unit 114 in the pixel group 11a located at the upper right.
