[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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, since the OPD unit occupies the area of ​​the pixel light-emitting area, the pixel light-emitting area ratio is reduced, the aperture ratio is reduced, and thus the display effect is reduced.

[0139] 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 method for manufacturing the same, and a display device, by arranging at least some of the sub-pixels in the first pixel group around the center of the first pixel group, and making the straight line where the edge of each sub-pixel in at least some of the sub-pixels is away from the center of the first pixel group to form a first polygon, so that the first light sensing unit and the adjacent edges of the first polygon are parallel to each other. In this way, space can be effectively utilized, and the sub-pixels and the first light sensing unit can be arranged compactly, which is conducive to improving the aperture ratio and display effect.

[0140] First, refer to Figure 1-Figure 8 As shown, an embodiment of the present application provides a pixel arrangement structure 12 , which includes a plurality of first pixel groups and a plurality of first light sensing units 124 .

[0141] The plurality of first pixel groups are arranged at intervals along a first direction X. Each first pixel group includes a plurality of first pixel groups 12a arranged at intervals along a second direction Y. Each first pixel group 12a includes a plurality of sub-pixels. The first direction X intersects with the second direction Y. Exemplarily, the plurality of sub-pixels may include at least one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel. The first direction X may be perpendicular to the second direction Y.

[0142] Furthermore, at least one first light sensing unit 124 is provided between two adjacent first pixel groups 12a. In the same first pixel group 12a, at least some of the sub-pixels are arranged around the center of the first pixel group 12a. And in at least some of the sub-pixels, the straight lines where the edges of each sub-pixel away from the center of the first pixel group 12a are located form a first polygon, and the first light sensing unit 124 and the adjacent edges of the first polygon are parallel to each other. Exemplarily, the first light sensing unit 124 can be an OPD (Organic Photodiode).

[0143] Here, it can be understood that: the outer contour line of the first pixel group 12a is a first polygon. The center of the first pixel group 12a can be the geometric center of the first pixel group 12a.

[0144] Here, by arranging at least some of the sub-pixels in the same first pixel group 12a around the center of the first pixel group 12a, the sub-pixels in the first pixel group 12a can be arranged more evenly and compactly. By making the adjacent sides of the first light sensing unit 124 and the first polygon parallel to each other, the first light sensing unit 124 and the first polygon can each have a larger occupied space under the condition of equal spacing, which is conducive to increasing the occupied space of the first pixel group 12a, thereby facilitating the improvement of the aperture ratio, and further facilitating the improvement of the display effect.

[0145] In one embodiment, one first light sensing unit 124 or two first light sensing units 124 may be provided between two adjacent first pixel groups 12a. The embodiment of the present application does not limit the number of first light sensing units 124 between two first pixel groups 12a.

[0146] In one embodiment, the pixel arrangement structure 12 further includes a plurality of second pixel groups, and the plurality of second pixel groups and the plurality of first pixel groups are alternately arranged in sequence along the first direction X, that is, a second pixel group is provided between two adjacent first pixel groups, and a first pixel group is provided between two adjacent second pixel groups.

[0147] Each second pixel group row includes a plurality of second pixel groups 12b arranged at intervals along the second direction Y. The first pixel groups 12a in the first pixel group row and the second pixel groups 12b in the second pixel group row are staggered.

[0148] Here, reference Figure 1 , Figure 2 and Figure 4 As shown, in Figure 1In the figure, the first row and the third row from top to bottom are the first pixel group row, and the second row is the second pixel group row. The second pixel group 12b in the second pixel group row is located obliquely below the two adjacent first pixel groups 12a, that is, the second pixel group 12b is located directly below the middle position of the two adjacent first pixel groups 12a. In this way, a mosaic arrangement can be achieved, so that the pixel arrangement structure 12 is relatively compact, the space utilization rate is improved, and it is beneficial to improve the aperture ratio.

[0149] In one embodiment, referring to Figure 1 and Figure 4 As shown, in the same second pixel group 12b, at least some of the sub-pixels are arranged around the center of the second pixel group 12b, and in the at least some of the sub-pixels, the straight lines where the edges of each sub-pixel away from the center of the second pixel group 12b are located form a second polygon. The adjacent edges of the first light sensing unit 124 and the second polygon are parallel to each other.

[0150] Here, it can be understood that: the outer contour line of the second pixel group 12b is a second polygon. The center of the second pixel group 12b can be the geometric center of the second pixel group 12b. By arranging at least part of the sub-pixels in the same second pixel group 12b around the center of the second pixel group 12b, the sub-pixels in the second pixel group 12b can be arranged more uniformly and compactly.

[0151] In one embodiment, the first polygon is a regular polygon. For example, the first polygon can be a regular quadrilateral, a regular pentagon, a regular hexagon, a regular heptagon, a regular octagon, etc. Figure 3 The dotted line in the figure is the first polygon.

[0152] In one embodiment, the first polygon is a regular octagon. This is conducive to realizing a mosaic arrangement of the first pixel group 12a and the second pixel group 12b, thereby making the pixel arrangement structure 12 more compact, improving space utilization, and further facilitating improving the aperture ratio.

[0153] In one embodiment, the second polygon is a regular polygon. For example, the second polygon can be a regular quadrilateral, a regular pentagon, a regular hexagon, a regular heptagon, a regular octagon, etc. Figure 5 The dotted line in the figure is the second polygon.

[0154] In one embodiment, the second polygon is a regular octagon. This is conducive to realizing a mosaic arrangement of the first pixel group 12a and the second pixel group 12b, thereby making the pixel arrangement structure 12 more compact, improving space utilization, and further facilitating improving the aperture ratio.

[0155] In one embodiment, referring to Figure 2 and Figure 3As shown, the first pixel group 12a includes a first sub-pixel 121, a second sub-pixel 122 and a third sub-pixel 123.

The first light sensing unit 124 and the second light sensing unit 126 are both OPDs. Figure 1 and Figure 6 In the pixel arrangement structure 12 shown. OPD is surrounded by four groups of G pixels, and each group of G pixels includes two G pixels. Among them, in the figure, the two groups of G pixels on the left and right sides of OPD are display pixels, and the two groups of G pixels on the upper and lower sides of OPD are compensation pixels 125. In RGB display, the display pixels can provide light source signals for OPD. When the screen brightness is low and the light source signal is weak, the compensation pixels 125 can be turned on to provide light source signals for OPD. Furthermore, the compensation pixels 125 can also be turned on under other special display conditions. In summary, the compensation pixels 125 have at least two functions: First, in the screen-off state, when OPD is recognized, only the compensation pixels 125 are lit, and the entire screen does not need to be lit. Second, in the outdoor state, when OPD is recognized, the four groups of G pixels around OPD can be lit to improve the signal recognition strength.

In this way, the first light sensing units 124 can be arranged more evenly, which is beneficial to improving the fingerprint recognition sensitivity.

[0243] Second, combining Fig. 20 , Fig.21 and Fig.23As shown, the embodiment of the present application provides a display panel 10, including a substrate 11 and a pixel arrangement structure 12 as in any embodiment of the first aspect, and the pixel arrangement structure 12 is disposed on the substrate 11. Exemplarily, the substrate 11 may include a substrate 112 and a driving structure layer 111.

[0244] In one embodiment, the display panel 10 further includes a reflective structure 14 disposed on the substrate 11, wherein the reflective structure 14 is disposed around the outer periphery of the first sub-pixel 121 of the pixel arrangement structure 12. Since the stray light emitted by the pixels around the OPD (the first light sensing unit 124 or the second light sensing unit 126) will affect the OPD signal recognition sensitivity, by arranging the reflective structure 14 around the first sub-pixel 121, the stray light emitted by the first sub-pixel 121 can be reflected by the reflective structure 14, which not only reduces the influence of the stray light on the OPD signal recognition, but also improves the light extraction efficiency.

[0245] Furthermore, the reflective structure 14 in the embodiment of the present application can also replace the support column in the evaporation process to isolate the mask from contacting the substrate 11 and prevent the substrate 11 from being scratched.

[0246] In one embodiment, a reflective structure 14 is provided around the outer periphery of the compensation pixel 125 of the pixel arrangement structure 12. In this way, the stray light emitted by the compensation pixel 125 can be reflected by the reflective structure 14, thereby reducing the influence of the stray light on the OPD signal recognition.

[0247] In one embodiment, in the application scenario of full-color recognition, a reflective structure 14 is provided around the outer periphery of the second sub-pixel 122 of the pixel arrangement structure 12. In this way, the stray light emitted by the second sub-pixel 122 can be reflected by the reflective structure 14, thereby reducing the influence of the stray light on the OPD signal recognition.

[0248] In one embodiment, in the application scenario of full-color recognition, a reflective structure 14 is provided around the outer periphery of the third sub-pixel 123 of the pixel arrangement structure 12. In this way, the stray light emitted by the third sub-pixel 123 can be reflected by the reflective structure 14, thereby reducing the influence of the stray light on the OPD signal recognition.

[0249] In one embodiment, the reflective structure 14 includes a dam 141 and a reflective layer 142 covering the dam 141. For example, the dam 141 may be made of an organic material, and the reflective layer 142 may be made of a metal material, which is beneficial to reducing the manufacturing cost of the reflective structure 14.

[0250] In one embodiment, the display panel 10 further includes a partition structure 15, and the partition structure 15 is disposed around the outer periphery of the first light sensing unit 124. The partition structure 15 is used to partition the organic common film layer of the sub-pixels.

[0251] Since the working principles of OPD and sub-pixel are opposite, when displaying, the charge will be transferred laterally to OPD. In the process of converting optical signal into electrical signal, the laterally transferred charge amplifies the electrical signal, which affects the recognition accuracy of OPD. Therefore, a partition structure 15 is provided around OPD to separate the organic common layer 162 and prevent the charge from being transferred laterally to OPD. It should be noted that the partition structure 15 can only separate the organic common film layer without cutting off the cathode to ensure the transmission of current.

[0252] In one embodiment, the display panel 10 further includes a pixel definition layer 13 disposed on the substrate 11, the pixel definition layer 13 defines a pixel opening and a light sensing opening, the sub-pixels of the pixel arrangement structure 12 are disposed in the pixel opening, and the first light sensing unit 124 and the second light sensing unit 126 of the pixel arrangement structure 12 are disposed in the light sensing opening.

[0253] Specifically, the pixel opening may include a first pixel opening, a second pixel opening and a third pixel opening, the first sub-pixel 121 is arranged in the first pixel opening, the second sub-pixel 122 is arranged in the second pixel opening, and the third sub-pixel 123 is arranged in the third pixel opening.

[0254] In one embodiment, the pixel definition layer 13 is provided with a partition groove 151, which is arranged around the outer periphery of the light sensing opening, and the partition groove 151 constitutes the partition structure 15. By providing the partition groove 151, the manufacturing cost of the partition structure 15 can be reduced.

[0255] It is understandable that one or more circles of partition grooves 151 may be provided around the periphery of the light sensing opening.

[0256] In one embodiment, the cavity of the partition groove 151 gradually increases from the opening to the groove bottom.

[0257] In one embodiment, the cross-section of the partition groove 151 is a regular trapezoid.

[0258] In one embodiment, the surface of the pixel definition layer 13 is provided with a reflective layer 142, and the partition groove 151 starts from the side of the reflective layer 142 away from the substrate 11 and extends toward the substrate 11. Specifically, the partition groove 151 is opened on the reflective layer 142 and the pixel definition layer 13.

[0259] In one embodiment, the distance between the reflective structure 14 and the first pixel opening is between 3 μm and 5 μm.

[0260] In one embodiment, the width of the reflective structure 14 is between 5 μm and 10 μm.

[0261] In one embodiment, the height of the reflective structure 14 is ≥ 1.6 μm.

[0262] The above arrangement can make the reflective structure 14 have a better reflective effect.

[0263] In one embodiment, the opening width of the partitioning groove 151 may be ≥3 μm, and the distance between two adjacent partitioning grooves 151 may be ≥3 μm.

[0264] In one embodiment, the depth of the partition groove 151 may be less than 0.5 μm and greater than 0.2 μm.

[0265] The above arrangement can make the partition groove 151 have a better partition effect.

[0266] In one embodiment, the display panel 10 further includes an encapsulation layer 17 , and the encapsulation layer 17 covers the sub-pixels and the reflective structure 14 .
