[0056] Aspects and exemplary embodiments of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application. In the drawings and the following description, at least some of the well-known structures and techniques are not shown in order to avoid unnecessarily obscuring the present application; and, for clarity, the dimensions of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0057] In the description of the present application, it should be noted that unless otherwise specified, the meaning of "a plurality" is two or more; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0058] The orientation terms appearing in the following description are all the directions shown in the figures, and do not specifically limit the structure of the embodiments of the present application. In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0059] Biometric identification plays an important role in mobile terminals such as smartphones and tablets. In the prior art, the common methods include face recognition and fingerprint recognition. Among them, fingerprint recognition includes ultrasonic fingerprint, capacitive fingerprint, and optical fingerprint, etc. Optical fingerprint has become the mainstream technical means due to its advantages such as high resolution, high sensitivity, and the ability to perform life and health detection.

[0060] Such as Figure 1As shown in the figure, the light emitted by the organic light-emitting diode (OLED) light-emitting unit in the related art is reflected by the user's fingerprint to the organic photo-diode (OPD) unit. The OPD unit converts the optical signal into an electrical signal, thereby realizing the recognition of the user's fingerprint information. However, the OPD unit requires high sensitivity to recognize the optical signal, and a high-dust test environment, a high-dust usage environment, a low transmittance or strong granularity of the module film layer, etc. will affect the OPD fingerprint recognition effect.

[0061] To solve the above technical problems, the present application is proposed. To better understand the present application, the following will be described in detail in conjunction with Figures 2 to 12 the pixel arrangement structure, display panel and display device according to the embodiments of the present application.

[0062] Please refer to Figures 2 to 10 , Figure 2 which is a schematic structural diagram of a repeating unit in a pixel arrangement structure provided by an embodiment of the first aspect of the present application, Figure 3 which is a schematic structural diagram of a pixel arrangement structure provided by an embodiment of the first aspect of the present application, Figure 4 is Figure 2 a schematic structural diagram of the orthographic projection of the first pixel and the photosensitive pixel in the repeating unit shown on a plane parallel to the row direction and the column direction, Figure 5 which is a schematic structural diagram of a repeating unit in a pixel arrangement structure provided by another embodiment of the first aspect of the present application, Figure 6 which is a schematic structural diagram of a pixel arrangement structure provided by another embodiment of the first aspect of the present application, Figure 7 which is a schematic structural diagram of a pixel unit in a pixel arrangement structure provided by another embodiment of the first aspect of the present application, Figure 8 which is a schematic structural diagram of a repeating unit in a pixel arrangement structure provided by still another embodiment of the first aspect of the present application, Figure 9 which is a schematic structural diagram of a pixel arrangement structure provided by still another embodiment of the first aspect of the present application, Figure 10 which is a schematic structural diagram of a pixel unit in a pixel arrangement structure provided by still another embodiment of the first aspect of the present application.

[0063] As Figure 2 and Figure 3 shown, an embodiment of the first aspect of the present application provides a pixel arrangement structure 20, which includes a plurality of light-emitting pixels and a photosensitive pixel 17. The plurality of light-emitting pixels include a first pixel 11 and a second pixel 13 with different colors. The photosensitive pixel 17 is configured to sense the light emitted by at least the first pixel 11 among the plurality of light-emitting pixels and reflected by the touch body to the photosensitive pixel 17. Among them, the first pixel 11 is annular and arranged around the photosensitive pixel 17.

[0064] Optionally, the touch body can be a user's finger or other part of the body, or other touch aids such as a stylus.

[0065] Exemplarily, the touch body is a user's finger. Correspondingly, after the light emitted by the multiple light-emitting pixels reaches the screen surface, it is reflected by the finger fingerprint to the photosensitive pixel 17, so that the photosensitive pixel 17 can perform fingerprint recognition at least according to the reflected light of the light emitted by at least the first pixel 11 among the multiple light-emitting pixels and reflected by the touch body to the photosensitive pixel 17. Therefore, the photosensitive pixel 17 can be used for finger fingerprint recognition.

[0066] Optionally, the light emitted by the first pixel 11 is one of red light, green light, or blue light, and the light emitted by the second pixel 13 is another of red light, green light, or blue light. In other words, the first pixel 11 and the second pixel 13 have different colors.

[0067] In the pixel arrangement structure 20 of the present application, the pixel arrangement structure 20 includes multiple light-emitting pixels and a photosensitive pixel 17. The multiple light-emitting pixels include a first pixel 11 and a second pixel 13 with different colors. At least the light emitted by the first pixel 11 among the multiple light-emitting pixels is reflected by the touch body to the photosensitive pixel 17 for the photosensitive pixel 17 to sense light. When the pixel arrangement structure 20 is used in a display panel, the light-emitting pixels with different colors emit light to achieve the display function of different color displays of the display panel. The photosensitive pixel 17 can sense light to achieve photosensitive functions such as biometric recognition. In addition, since the first pixel 11 is annular and arranged around the photosensitive pixel 17, the optical path and optical path difference of the light emitted by at least the first pixel 11 among the multiple light-emitting pixels and reflected by the touch body to the photosensitive pixel 17 can be reduced compared with the related art. On the one hand, in scenarios such as a high-dust test environment, a high-dust usage environment, a low transmittance or strong granularity of the module film layer, the reduction of the optical path of the light can make the response of the photosensitive pixel 17 faster during the photosensitive process and the light attenuation of the light decrease, so that a fast and efficient photosensitive function can be achieved. On the other hand, the reduction of the optical path difference of the light can make the uniformity of the light intensity received by each part of the photosensitive pixel 17 better.

[0068] Optionally, the number of the photosensitive pixels 17 is the same as that of the first pixels 11.

[0069] Optionally, as Figure 2 and Figure 4As shown, the photosensitive pixel 17 is arranged at equal intervals from the first pixel 11. Specifically, the first pixel 11 forms a first orthographic projection 11A on a plane parallel to the row direction X and the column direction Y, and the photosensitive pixel 17 forms a second orthographic projection 17A on a plane parallel to the row direction X and the column direction Y. The minimum distance between any two points on the outer periphery of the second orthographic projection 17A and the first orthographic projection 11A is the same. On the one hand, the manufacturing difficulty of the photosensitive pixel 17 can be reduced. On the other hand, when the light emitted by the first pixel 11 is reflected by the touch body to the photosensitive pixel 17, the optical distances of the light rays are closer, so that the uniformity of the photosensitive intensity of each region of the photosensitive pixel 17 can be further improved.

[0070] Optionally, the distance between the photosensitive pixel 17 and the first pixel 11 is not less than 1.50 Å. The smaller the distance between the photosensitive pixel 17 and the first pixel 11, the more beneficial it is to increase the photosensitive area of the photosensitive pixel 17 and / or the light-emitting area of the first pixel 11 when the outer contour area of the first pixel 11 is the same. Among them, the increase in the photosensitive area of the photosensitive pixel 17 can improve the photosensitive sensitivity, and the increase in the light-emitting area of the first pixel 11 can improve the light-emitting performance. However, the smaller the distance between the photosensitive pixel 17 and the first pixel 11, the greater the manufacturing difficulty of the photosensitive pixel 17. Therefore, considering comprehensively, the distance between the photosensitive pixel 17 and the first pixel 11 is not less than 1.50 Å.

[0071] Exemplarily, the distance between the photosensitive pixel 17 and the first pixel 11 can be 1.50 Å, 1.52 Å, 1.54 Å, 1.56 Å, 1.58 Å, 1.60 Å, 1.62 Å, 1.64 Å, 1.66 Å, 1.68 Å, 1.70 Å, 1.72 Å, 1.74 Å, 1.76 Å, 1.78 Å, 1.80 Å, 1.82 Å, 1.84 Å, 1.86 Å, 1.88 Å, 1.90 Å, 1.92 Å, 1.94 Å, 1.94 Å, 1.96 Å, 1.98 Å or 2.00 Å, etc. Of course, the distance between the photosensitive pixel 17 and the first pixel 11 can also be any combination range of the above values.

[0072] Optionally, the light-emitting area of the first pixel 11 is larger than the photosensitive area of the photosensitive pixel 17. On the one hand, the photosensitive intensity of the photosensitive pixel 17 can be ensured to improve the photosensitive sensitivity. On the other hand, the light-emitting effect of the first pixel 11 can be ensured.

[0073] Optionally, the shape of the first pixel 11 matches the shape of the photosensitive pixel 17.

[0074] Exemplarily, as Figure 2 and Figure 3 shown, the shape of the photosensitive pixel 17 is rectangular. Correspondingly, the shape of the first pixel 11 is a rectangular ring to match the shape of the photosensitive pixel 17; asFigure 6 As shown, the shape of the photosensitive pixel 17 is a runway shape. Correspondingly, the shape of the first pixel 11 is a runway-shaped ring to match the shape of the photosensitive pixel 17; as Figure 9 shown, the shape of the photosensitive pixel 17 is circular. Correspondingly, the shape of the first pixel 11 is a circular ring to match the shape of the photosensitive pixel 17.

[0075] Optionally, the plurality of light-emitting pixels further includes a third pixel 15, and the color of the third pixel 15 is different from the colors of both the first pixel 11 and the second pixel 13.

[0076] Further optionally, the photosensitive pixel 17 only senses the light emitted by the first pixel 11.

[0077] In some optional embodiments, after the light emitted by the first pixel 11, the second pixel 13, and the third pixel 15 reaches the screen surface, it is reflected by the touch body to the photosensitive pixel 17, so that the photosensitive pixel 17 can perform fingerprint recognition according to the reflected light of the light emitted by the first pixel 11. During this process, since the first pixel 11 is annular and arranged around the photosensitive pixel 17, and there is also an interval between the first pixel 11 and the photosensitive pixel 17, the optical path and light intensity of the light emitted by the first pixel 11 reflected to the photosensitive pixel 17 are both greater than the optical path and light intensity of the light emitted by the second pixel 13 and the third pixel 15 reflected to the photosensitive pixel 17. Thus, during the process of the photosensitive pixel 17 performing fingerprint recognition according to the reflected light of the light emitted by the first pixel 11, the interference of other optical signals can be reduced, and the influence on the signal recognition and the sensitivity of the display panel photosensing can be reduced.

[0078] In other embodiments, the photosensitive pixel 17 can also sense the light emitted by the third pixel 15 or / and the second pixel 13 and reflected to the photosensitive pixel 17 by the touch body.

[0079] In these optional embodiments, the pixel arrangement structure 20 has a plurality of repeating units 1 arranged in an array in the row direction X and the column direction Y. The repeating unit 1 includes a plurality of light-emitting pixels and the photosensitive pixel 17.

[0080] There are various ways to set the row direction X and the column direction Y. The row direction X and the column direction Y can be set to intersect at any preset angle.

[0081] In some optional embodiments, the included angle between the row direction X and the column direction Y is 90 degrees, such as Figure 2 and Figure 3 the X-axis (row direction X) and the Y-axis (column direction Y) shown in, so that each of the first pixel 11, the second pixel 13, and the third pixel 15 can be arranged horizontally and vertically along the horizontal and vertical directions, with a simple structure and convenient manufacturing.

[0082] In some optional embodiments, such asFigure 2 and Figure 3 As shown in Figure 3 , the photosensitive pixel 17, the second pixel 13, and the third pixel 15 are all rectangular.

[0083] In some alternative embodiments, the angle between the row direction X and the column direction Y is less than 90 degrees, such as the X-axis (row direction X) and the Y-axis (column direction Y) shown in Figure 6 . Therefore, the first pixels 11, the second pixels 13, and the third pixels 15 can be arranged vertically along the vertical direction, with a simple structure and convenient manufacturing. Figure 6 and Figure 9 As shown in Figure 9 , the photosensitive pixel 17, the second pixel 13, and the third pixel 15 are all racetrack-shaped.

[0084] In some alternative embodiments, as shown in Figure 6 Figure 6 the photosensitive pixel 17, the second pixel 13, and the third pixel 15 are all circular.

[0085] In some alternative embodiments, as shown in Figure 9 Figure 9 the photosensitive pixel 17, the second pixel 13, and the third pixel 15 are all circular.

[0086] In other embodiments, the row direction X can also be the direction where the Y-axis is located, and the column direction Y can also be the direction where the X-axis is located; the photosensitive pixel 17, the second pixel 13, and the third pixel 15 can also be in other shapes.

[0087] In some alternative embodiments, as shown in Figure 2 Figure 2 and Figure 3 as shown in Figure 3 , in the repeating unit 1, the quantity ratio of the first pixel 11, the second pixel 13, and the third pixel 15 is 2:1:1.

[0088] In some alternative embodiments, the repeating unit 1 has a first pixel row 101 and a second pixel row 103 arranged along the column direction Y. The first pixel row 101 includes n first pixels 11 and n second pixels 13 arranged along the row direction X, and the second pixel row 103 includes m third pixels 15 and m first pixels 11 arranged along the row direction X.

[0089] In some alternative embodiments, in adjacent first pixel row 101 and second pixel row 103, the number of the first pixels 11 is n + m, the number of the photosensitive pixels 17 is n + m, the number of the second pixels 13 is n, and the number of the third pixels 15 is m. Making the number of the first pixels 11 more than that of other pixels can, on the one hand, avoid the problem of the reduction of the light-emitting performance of the first pixels 11 caused by the setting of the photosensitive pixels 17 to ensure the light effect of the first pixels 17, and on the other hand, can increase the photosensitive area and the photosensitive amount to improve the photosensitive sensitivity of the display panel.

[0090] Optionally, both n and m are 1, enabling a more balanced distribution of the first pixel 11, the second pixel 13, and the third pixel 15, and improving the local color deviation problem of the display panel caused by the concentrated arrangement of the light-emitting pixels of the same color.

[0091] Optionally, as Figure 2 and Figure 3 shown, the first pixel 11 of the first pixel row 101 and the third pixel 15 of the second pixel row 103 are arranged side by side along the column direction Y; and / or, the second pixel 13 of the first pixel row 101 and the first pixel 11 of the second pixel row 103 are arranged side by side along the column direction Y. This reduces the distance between the light-emitting pixels of different colors and improves the display effect of the display panel.

[0092] Exemplarily, the first pixel 11 of the first pixel row 101 and the third pixel 15 of the second pixel row 103 are arranged side by side along the column direction Y, and the second pixel 13 of the first pixel row 101 and the first pixel 11 of the second pixel row 103 are arranged side by side along the column direction Y.

[0093] Optionally, each repeating unit 1 constitutes a pixel unit. The pixel unit is used to emit white light, which can reduce the distance between the light-emitting pixels of different colors within the pixel unit and improve the display effect.

[0094] In some other optional embodiments, as Figure 5 and Figure 8 shown, in the repeating unit 1, the quantity ratio of the first pixel 11, the second pixel 13, and the third pixel 15 is 1:1:1.

[0095] In some optional embodiments, the repeating unit 1 includes n first pixels 11, n third pixels 15, and n second pixels 13 arranged along the column direction Y.

[0096] Optionally, n is 1, enabling a more balanced distribution of the first pixel 11, the second pixel 13, and the third pixel 15, and improving the local color deviation problem of the display panel caused by the concentrated arrangement of the light-emitting pixels of the same color.

[0097] As Figure 6 and Figure 9 shown, two adjacent repeating units 1 along the row direction X are arranged in a staggered manner in the column direction Y. The staggered arrangement of two adjacent repeating units 1 along the row direction X in the column direction Y makes the row direction X and the column direction Y not perpendicular, but rather an angle less than 90 degrees between the row direction X and the column direction Y.

[0098] In some optional embodiments, as Figure 6As shown, in two adjacent repeating units 1 along the row direction X, the second pixel 13, a first pixel 11 and a third pixel 15 adjacent to the second pixel 13 in the row direction X form a pixel unit. The pixel unit is used to emit white light, which can reduce the distance between light-emitting pixels of different colors within the pixel unit and improve the display effect.

[0099] In some alternative embodiments, as Figure 7 shown, in the pixel unit, the connecting lines of the centers of the first pixel 11, the second pixel 13 and the third pixel 15 form a first triangle A.

[0100] Optionally, the first triangle A is an isosceles triangle or an equilateral triangle.

[0101] In some alternative embodiments, as Figure 6 and Figure 10 shown, in the pixel arrangement structure 20, three adjacent first pixels 11 form a second triangle B, and the three adjacent first pixels 11 cooperate to emit light together. It is possible to avoid the problem of reduced light-emitting performance of the first pixel 11 caused by the arrangement of the photosensitive pixels 17, thereby ensuring the light effect of the first pixel 17.

[0102] In some alternative embodiments, as Figure 9 and Figure 10 shown, the second pixel 13, three first pixels 11 adjacent to the second pixel 13 and three third pixels 15 form a pixel unit.

[0103] In some alternative embodiments, in the pixel unit, the centers of the first pixel 11 and the third pixel 15 are located on the same hexagon C.

[0104] Optionally, the hexagon C is a regular hexagon.

[0105] In some alternative embodiments, as Figure 9 shown, two adjacent pixel units share one side length of the hexagon C. That is, two adjacent pixel units share a first pixel 11 and a third pixel 15.

[0106] In the above embodiment, the first pixel 11 is a green pixel. In the visible light spectrum, the energy of green light photons is relatively moderate, such that the green light-sensitive photosensitive pixel 17 is more sensitive to green light, and can more effectively capture the green light signal emitted by the first pixel 11 and reflected by the touch body to the photosensitive pixel 17; in addition, in a test environment with high dust production, a usage environment with high dust production, an environment with low transmittance or strong granularity of the module film layer, etc., green light has better penetration ability than light of other colors. Therefore, in these specific scenarios, the photosensitivity of the photosensitive pixel 17 can be further improved. In addition, the noise generated by the green light-sensitive photosensitive pixel 17 during operation is relatively low, which helps to improve the photosensitive response. Among them, the green light-sensitive photosensitive pixel 17 means that the photosensitive pixel 17 is only configured to sense the green light emitted by the first pixel 11.

[0107] In the above embodiment, the second pixel 13 is a blue pixel, the third pixel 15 is a red pixel, and the light-emitting area of the second pixel 13 is larger than that of the third pixel 15.

[0108] In the above embodiment, the light-emitting area of the third pixel 15 is larger than that of the first pixel 11. The light-emitting area of the second pixel 13 is larger than that of the third pixel 15, and the light-emitting area of the third pixel 15 is larger than that of the first pixel 11, such that the area of the blue pixels in the pixel arrangement structure 20 is relatively large. Therefore, the defect of the relatively short lifespan of the blue pixels caused by the inherent characteristics of the blue light-emitting material can be improved to enhance the lifespan and display effect of the display panel.

[0109] In the above embodiment, the photosensitive pixel 17 and the correspondingly arranged first pixel 11 form a pixel group 19, and in the repeating unit 1, one or more pixel groups 19 are provided.

[0110] Optionally, as Figure 1 shown, in the repeating unit 1, two pixel groups 19 are provided.

[0111] As Figure 5 and Figure 8 shown, in the repeating unit 1, one pixel group 19 is provided.

[0112] Continuing to refer to Figure 11 and Figure 12 , Figure 11 is a schematic structural diagram of a partial structure of a display panel provided by an embodiment of the second aspect of the present application, Figure 12 is Figure 11 a schematic structural diagram of the orthographic projection on the substrate of the inner wall of the first opening and the inner wall of the photosensitive opening in the partial structure of the shown display panel.

[0114] Optionally, the display panel has a light-transmitting display area, and the pixel arrangement structure 20 provided in any of the first aspect embodiments can be arranged in the light-transmitting display area, or the pixel arrangement structure 20 provided in any of the first aspect embodiments can be arranged in all display areas of the display panel.

[0115] In some embodiments, a first conductive layer 30 and a second conductive layer 40 located on the side of the first conductive layer 30 facing away from the substrate 10 are provided on the substrate 10, and the photosensitive pixel 17 includes a first electrode 171 located in the first conductive layer 30, and the first pixel 11 includes a second electrode 111 located in the second conductive layer 40. The first electrode 171 and the second electrode 111 are arranged in layers to facilitate the wiring of the first electrode 171 and the second electrode 111 to be connected to the circuit.

[0116] Optionally, the first electrode 171 and the second electrode 111 are both anodes.

[0118] Optionally, the substrate 10 has a driving circuit, and the leads of the first electrode 171 and the second electrode 111 are connected to the driving circuit of the substrate 10 .

[0119] Optionally, the photosensitive pixel 17, the first pixel 11 and other light-emitting pixels can be prepared by using an evaporation + fine metal mask (Fine Metal Mask, FMM) process or an evaporation + photolithography process.

[0120] In some embodiments, the substrate 10 is further provided with an insulating layer 50 located between the substrate 10 and the second conductive layer 40 and a pixel definition layer 60 located on the side of the insulating layer 50 away from the substrate 10, the insulating layer 50 is provided with a first opening 501 for exposing the first electrode 171, the pixel definition layer 60 is provided with a pixel opening 601 for exposing the second electrode 111 and a photosensitive opening 603 connected to the first opening 501, so as to reduce the manufacturing difficulty of the display panel.

[0121] In some embodiments, Figure 12As shown, the inner wall of the photosensitive opening 603 forms a first projection 605 in the orthographic projection on the substrate 10, and the inner wall of the first opening 501 forms a second projection 503 in the orthographic projection on the substrate 10. The second projection 503 is within the range of the first projection 605. This is to further reduce the manufacturing difficulty of the display panel.
