[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0042] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0043] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and material examples provided by the present application, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0045] In the prior art, the arrangement of multiple red sub-pixels, multiple green pixels, and multiple blue sub-pixels in the CUP area of ​​the display panel is consistent with or similar to the arrangement of multiple red sub-pixels, multiple green pixels, and multiple blue sub-pixels in the AA area. For example, the red sub-pixels, green pixels, and blue sub-pixels in the CUP area and the AA area are arranged in accordance with the SPR arrangement (for example, arranged in an RGBG array or arranged in a BGRG array). However, based on the existing pixel arrangement, since the red sub-pixels, green pixels, and blue sub-pixels include an opaque structure and are arranged densely, diffraction of visible light is formed in the CUP area, resulting in poor imaging effect of the photosensitive device arranged in the CUP area.

[0046] In order to solve the above technical problems, the present application reduces the influence of the diffraction effect on the imaging effect of the photosensitive device by optimizing the pixel arrangement of the CUP area while ensuring the display effect of the CUP area. Please refer to the description of the following embodiments for details.

[0047] like Figure 2 and Figure 3 As shown, an embodiment of the present application provides a display panel 1, which includes a first display area 2 and a second display area 3 arranged adjacent to each other; the transmittance of the first display area 2 is greater than the transmittance of the second display area 3. The display panel 1 includes a substrate 4 and a light-emitting layer 5 arranged on one side of the substrate 4; the light-emitting layer 5 includes a plurality of first sub-pixels 6 displaying a first color and a plurality of second sub-pixels 7 displaying a second color. Among them, the first display area 2 includes a plurality of first sub-display areas 2a; the second display area 3 includes a plurality of second sub-display areas 3a; the first sub-display areas 2a and the second sub-display areas 3a have the same shape and the same area; the number of first sub-pixels 6 located in the first sub-display area 2a is less than the number of first sub-pixels 6 located in the second sub-display area 3a, and the area of ​​the first sub-pixels 6 located in the first sub-display area 2a is greater than the area of ​​the first sub-pixels 6 located in the second sub-display area 3a; the number of second sub-pixels 7 located in the first sub-display area 2a is equal to the number of second sub-pixels 7 located in the second sub-display area 3a.

[0048] Specifically, the first display area 2 of the display panel 1 is a CUP area, which is used to set a photosensitive device (such as an under-screen camera CUP) and provide a lighting channel for the photosensitive device to realize the under-screen photosensing function, and is also used for display to realize the full-screen display function.

[0049] Specifically, a plurality of first sub-display areas 2a are arranged along a first direction and a second direction, and the first direction and the second direction are arranged to intersect each other; a plurality of second sub-display areas 3a are arranged along the first direction and the second direction. The embodiment of the present application is described by taking the first direction as a horizontal direction and the second direction as a vertical direction as an example, but is not limited thereto.

[0050] In a specific embodiment, the total area of ​​all first sub-pixels 6 located in the first sub-display area 2a is equal to the total area of ​​all first sub-pixels 6 located in the second sub-display area 3a, but is not limited thereto.

[0051] Compared with the prior art, the present application can effectively increase the area of ​​the light-transmitting region of the first display area 2 by reducing the number of first sub-pixels 6 in the first display area 2, so that the number of first sub-pixels 6 in the first sub-display area 2a is less than the number of first sub-pixels 6 in the second sub-display area 3a of the same area, which is conducive to reducing the diffraction effect of the first display area 2. Moreover, on the basis that the number of first sub-pixels 6 in each first sub-display area 2a is small, by increasing the area of ​​a single first sub-pixel 6 in the first display area 2, the area of ​​a single first sub-pixel 6 in the first sub-display area 2a is larger than the area of ​​a single first sub-pixel 6 in the second sub-display area 3a, which is conducive to ensuring that the total area of ​​all first sub-pixels 6 in the first sub-display area 2a is equal to the total area of ​​the first sub-pixels 6 in the second sub-display area 3a, thereby ensuring that the display effect of the first display area 2 is not affected by the reduction in the number of first sub-pixels 6, that is, ensuring that the display brightness of the first display area 2 and the second display area 3 are consistent.

[0052] It should be noted that the area of ​​the first sub-pixel 6 , the area of ​​the second sub-pixel 7 , and the area of ​​the third sub-pixel 8 described below all refer to the area of ​​a single sub-pixel.

[0053] Specifically, the area of ​​the second sub-pixel 7 located in the first sub-display area 2a is smaller than or equal to the area of ​​the second pixel located in the second sub-display area 3a.

[0054] Since the number of first sub-pixels 6 in each first sub-display area 2a in the first display area 2 is less than the number of first sub-pixels 6 in each second sub-display area 3a in the second display area 3, in order to avoid uneven display between the first display area 2 and the second display area 3, the area of ​​the first sub-pixel 6 in the first sub-display area 2a needs to be increased. When the area increase of the first sub-pixel 6 in the first sub-display area 2a is small to meet the display demand, the area of ​​the second sub-pixel 7 in the first sub-display area 2a is equal to the area of ​​the second sub-pixel 7 in the second sub-display area 3a, that is, there is no need to change the area size of other sub-pixels in the first sub-display area 2a; when the area increase of the first sub-pixel 6 in the first sub-display area 2a is large to meet the display demand, the area of ​​the second sub-pixel 7 in the first sub-display area 2a is smaller than the area of ​​the second sub-pixel 7 in the second sub-display area 3a, that is, it is necessary to appropriately reduce the area of ​​the second sub-pixel 7 in the first sub-display area 2a to avoid other display problems caused by the over-large area design of the first sub-pixel 6 in the first sub-display area 2a.

[0055] Specifically, Figure 3 As shown, the center points of the first sub-pixels 6 are arranged along the first direction and the second direction in the first display area 2 and the second display area 3; the center points of the second sub-pixels 7 are arranged along the first direction and the second direction in the first display area 2 and the second display area 3.

[0056] In the first direction, the distance between the center points of two adjacent first sub-pixels 6 located in the first display area 2 is greater than the distance between the center points of two adjacent first sub-pixels 6 located in the second display area 3, and the distance between the center points of two adjacent second sub-pixels 7 located in the first display area 2 is equal to the distance between the center points of two adjacent second sub-pixels 7 located in the second display area 3.

[0057] In the second direction, the distance between the center points of two adjacent first sub-pixels 6 located in the first display area 2 is equal to the distance between the center points of two adjacent first sub-pixels 6 located in the second display area 3, and the distance between the center points of two adjacent second sub-pixels 7 located in the first display area 2 is equal to the distance between the center points of two adjacent second sub-pixels 7 located in the second display area 3.

[0058] It can be understood that the arrangement of the second sub-pixels 7 in the first display area 2 and the second display area 3 is consistent.

[0059] Specifically, only the number of first sub-pixels 6 arranged in the first direction in the first display area 2 can be reduced, so that the distance between the center points of two adjacent first sub-pixels 6 located in the first display area 2 in the first direction is greater than the distance between the center points of two adjacent first sub-pixels 6 located in the second display area 3, and the distance between the center points of two adjacent first sub-pixels 6 located in the first display area 2 in the second direction is equal to the distance between the center points of two adjacent first sub-pixels 6 located in the second display area 3.

[0060] It should be noted that the reduction in the number of first sub-pixels 6 in the first display area 2 is relative to the number of first sub-pixels 6 in the second display area 3 of the same area.

[0061] Specifically, Figure 3As shown, the light-emitting layer 5 further includes a plurality of third sub-pixels 8 displaying a third color, the number of the third sub-pixels 8 located in the first sub-display area 2a is equal to the number of the third sub-pixels 8 located in the second sub-display area 3a, and the area of ​​the third sub-pixels 8 located in the first sub-display area 2a is less than or equal to the area of ​​the third sub-pixels 8 located in the second sub-display area 3a. This design is also to balance the display brightness of the first display area 2 and the second display area 3, and avoid the problem of uneven brightness in the first display area 2 and the second display area 3.

[0062] Specifically, the center points of the third sub-pixels 8 are arranged along the first direction and the second direction in both the first display area 2 and the second display area 3. In the first direction, the spacing between the center points of two adjacent third sub-pixels 8 in the first display area 2 is equal to the spacing between the center points of two adjacent third sub-pixels 8 in the second display area 3; in the second direction, the spacing between the center points of two adjacent third sub-pixels 8 in the first display area 2 is equal to the spacing between the center points of two adjacent third sub-pixels 8 in the second display area 3.

[0063] It can be understood that the arrangement of the third sub-pixels 8 in the first display area 2 and the second display area 3 is consistent.

[0064] Specifically, in the first display area 2, the first sub-pixel 6, the second sub-pixel 7, and the third sub-pixel 8 are arranged according to the REAL RGB arrangement; in the second display area 3, the first sub-pixel 6, the second sub-pixel 7, and the third sub-pixel 8 are arranged according to the SPR arrangement.

[0065] Specifically, the first sub-pixel 6 includes a green sub-pixel (G), the second sub-pixel 7 includes any one of a red sub-pixel (R) and a blue sub-pixel (B), and the third sub-pixel 8 includes one of a red sub-pixel and a blue sub-pixel that is different from the second sub-pixel 7.

[0066] In the embodiment of the present application, the first sub-pixel 6 is a green sub-pixel, the second sub-pixel 7 is a red sub-pixel, and the third sub-pixel 8 is a blue sub-pixel. It can be understood that the first sub-pixel 6 displays green (first color), the second sub-pixel 7 displays red (second color), and the third sub-pixel 8 displays blue (third color).

[0067] Specifically, the first sub-pixel 6 , the second sub-pixel 7 and the third sub-pixel 8 are all composed of light-emitting devices, wherein the light-emitting devices include OLED devices, but are not limited thereto.

[0068] Specific, combined Figure 3 and Figure 4As shown, the first display area 2 is divided into a plurality of first sub-display areas 2a, each of which has a minimum sub-pixel repeating unit, such as a first sub-pixel repeating unit 9; the second display area 3 is divided into a plurality of second sub-display areas 3a, each of which has a minimum sub-pixel repeating unit, such as a second sub-pixel repeating unit 11. The first sub-pixel repeating unit 9 includes at least one first sub-pixel 6, at least one second sub-pixel 7, and at least one third sub-pixel 8, and the second sub-pixel repeating unit 11 includes at least two first sub-pixels 6, at least one second sub-pixel 7, and at least one third sub-pixel 8; the pixel arrangement in the first sub-pixel repeating unit 9 is the same as the pixel arrangement obtained by removing at least one first sub-pixel 6 in the second sub-pixel repeating unit 11.

[0069] It can be understood that the first sub-pixel repeating unit 9 is repeatedly arranged along the first direction and the second direction in the first display area 2 , and the second sub-pixel repeating unit 11 is repeatedly arranged along the first direction and the second direction in the second display area 3 .

[0070] like Figure 3 and Figure 4 As shown, the first pixel repetition unit 9 includes a first pixel unit 10 and a second pixel unit 12 spaced apart in the second direction; the first pixel unit 10 and the second pixel unit 12 each include a green sub-pixel (G), a red sub-pixel (R) and a blue sub-pixel (B), wherein the first pixel unit 10 is configured as a BGR triangle arrangement, and the second pixel unit 12 is configured as an RGB triangle arrangement.

[0071] It can be understood that the arrangement order of the red sub-pixels, green sub-pixels and blue sub-pixels in the second pixel unit 12 is different from that in the first pixel unit 10. Since the first pixel unit 10 and the second pixel unit 12 are both arranged in independent RGB triangles, the red sub-pixels, green sub-pixels and blue sub-pixels in the entire first display area 2 are arranged in a REAL RBG arrangement.

[0072] It should be noted that the embodiment of the present application does not limit the specific arrangement order of R, G and B in the first pixel unit 10 and the second pixel unit 12. In the embodiment of the present application, only the first pixel unit 10 is configured as a BGR triangle arrangement and the second pixel unit 12 is configured as an RGB triangle arrangement as an example for explanation.

[0073] Specifically, the red sub-pixels, green sub-pixels and blue sub-pixels in the first display area 2 are arranged according to the REAL RGB arrangement, which can significantly increase the size of the light-transmitting area in the first display area 2, which is beneficial to reducing the diffraction effect, thereby helping to improve the imaging effect of the photosensitive device.

[0074] Specifically, in the first display area 2, a plurality of first pixel units 10 are arranged in a plurality of rows and columns in the first direction and the second direction, and a plurality of second pixel units 12 are arranged in a plurality of rows and columns in the first direction and the second direction; any two adjacent rows of first pixel units 10 and second pixel units 12 are arranged in a one-to-one correspondence, and any two adjacent columns of first pixel units 10 and second pixel units 12 are arranged in a one-to-one correspondence. This design enables the first pixel units 10 arranged in a BGR triangle and the second pixel units 12 arranged in a BGR triangle to be evenly and regularly distributed in the first display area 2, which is conducive to ensuring the display effect of the first display area 2.

[0075] Specifically, Figure 3 and Figure 4 As shown, the second pixel repeating unit 11 includes a third pixel unit 13 and a fourth pixel unit 14 arranged at intervals in the second direction; the third pixel unit 13 and the fourth pixel unit 14 each include a red sub-pixel, a blue sub-pixel and two green sub-pixels; wherein the third pixel unit 13 is configured as a BGRG saw-shaped arrangement, and the fourth pixel unit 14 is configured as an RGBG saw-shaped arrangement. It can be understood that the pixel arrangement of the third pixel unit 13 and the fourth pixel unit 14 enables the red sub-pixels, blue sub-pixels and green sub-pixels in the entire second display area 3 to be arranged in an SPR arrangement.

[0076] Specifically, the first pixel unit 10 is the same as the pixel unit obtained by removing the terminal green sub-pixel based on the arrangement of the third pixel unit 13, and the second pixel unit 12 is the same as the pixel unit obtained by removing the terminal green sub-pixel based on the arrangement of the fourth pixel unit 14. It can be understood that the number and arrangement position of the red sub-pixels and the blue sub-pixels in the first pixel unit 10 and the third pixel unit 13 are consistent, and the number and arrangement position of the red sub-pixels and the blue sub-pixels in the second pixel unit 12 and the fourth pixel unit 14 are consistent.

[0077] Specifically, in the second display area 3, the plurality of third pixel units 13 are arranged in multiple rows and columns in the first direction and the second direction, the plurality of fourth pixel units 14 are arranged in multiple rows and columns in the first direction and the second direction, any two adjacent rows of third pixel units 13 and fourth pixel units 14 are arranged in one-to-one correspondence, and any two adjacent columns of third pixel units 13 and fourth pixel units 14 are arranged in one-to-one correspondence, so the green sub-pixels in the plurality of second pixel repeating units 11 in the second display area 3 are arranged in multiple rows and columns. In the second display area 3, any two adjacent rows of green sub-pixels are arranged in one-to-one correspondence, and any two adjacent columns of green sub-pixels are arranged in one-to-one correspondence.

[0078] Since the first pixel unit 10 and the second pixel unit 12 are equivalent to pixel units obtained by removing the terminal green sub-pixels based on the arrangements of the third pixel unit 13 and the fourth pixel unit 14, respectively, the pixel arrangement of the multiple first pixel repetition units 9 in the first display area 2 can be obtained by removing the multiple columns of green sub-pixels in the multiple second pixel repetition units 11 within the same area in every other column.

[0079] Specifically, in the first display area 2, the green sub-pixels in the plurality of first pixel repeating units 9 are arranged in multiple rows and columns, any two adjacent rows of green sub-pixels are arranged in one-to-one correspondence, and any two adjacent columns of green sub-pixels are arranged in one-to-one correspondence. In the first direction, the ratio of the spacing between the center points of two adjacent green sub-pixels in the first display area 2 to the spacing between the center points of two adjacent green sub-pixels in the second display area 3 is 2; and in the second direction, the ratio of the spacing between the center points of two adjacent green sub-pixels in the first display area 2 to the spacing between the center points of two adjacent green sub-pixels in the second display area 3 is 1.

[0080] Of course, in other embodiments, the first pixel repeating unit 9 may include only the first pixel unit 10 or the second pixel unit 12, and correspondingly, the second pixel repeating unit 11 includes the third pixel unit 13 or the fourth pixel unit 14. When the first pixel repeating unit 9 includes only the first pixel unit 10, the second pixel repeating unit 11 includes the third pixel unit 13, and the first pixel unit 10 is the same as the pixel unit obtained by removing the terminal green sub-pixel based on the arrangement of the third pixel unit 13. When the first pixel repeating unit 9 includes only the second pixel unit 12, the second pixel repeating unit 11 includes the fourth pixel unit 14, and the second pixel unit 12 is the same as the pixel unit obtained by removing the terminal green sub-pixel based on the arrangement of the fourth pixel unit 14.

[0081] Specifically, Figure 3 and Figure 5 As shown, the first display area 2 also includes a transition area 2b adjacent to the first sub-display area 2a. The display panel 1 further includes a driving circuit layer disposed between the substrate 4 and the light-emitting layer 5; the driving circuit layer includes a plurality of driving circuit units 15 disposed in the transition area 2b and electrically connected to the plurality of first pixel repeating units 9 in a one-to-one correspondence; the driving circuit units 15 include at least one first driving circuit 16, at least one second driving circuit 17, and at least one third driving circuit 18.

[0082] The first driving circuit 16 is electrically connected to the first sub-pixel 6 in the corresponding first pixel repeating unit 9, the second driving circuit 17 is electrically connected to the second sub-pixel 7 in the corresponding first pixel repeating unit 9, and the third driving circuit 18 is electrically connected to the third sub-pixel 8 in the corresponding first pixel repeating unit 9.

[0083] Specifically, the first sub-pixel 6 , the second sub-pixel 7 and the third sub-pixel 8 are all electrically connected to the corresponding driving circuits through the transparent wires 19 .

[0084] In a specific embodiment, Figure 3 As shown, the number of first sub-pixels 6 in each first pixel repeating unit 9 is equal to the number of first driving circuits 16 in the corresponding driving circuit unit 15, the number of second sub-pixels 7 in each first pixel repeating unit 9 is equal to the number of second driving circuits 17 in the corresponding driving circuit unit 15, and the number of third sub-pixels 8 in each first pixel repeating unit 9 is equal to the number of third sub-pixel 8 driving circuits in the corresponding driving circuit unit 15; each first driving circuit 16 is arranged corresponding to one first sub-pixel 6 and electrically connected to each other, each second driving circuit 17 is arranged corresponding to one second sub-pixel 7 and electrically connected to each other, and each third driving circuit 18 is arranged corresponding to one third sub-pixel 8 and electrically connected to each other. It can be understood that the driving circuits in this embodiment are one-to-one driven.

[0085] In another specific embodiment, Figure 5 As shown, the first pixel repeating unit 9 includes two first sub-pixels 6, two second sub-pixels 7, and two third sub-pixels 8; the driving circuit unit 15 includes a first driving circuit 16, a second driving circuit 17, and a third driving circuit 18; a first driving circuit 16 is electrically connected to the two first sub-pixels 6 in the corresponding first pixel repeating unit 9, a second driving circuit 17 is electrically connected to the two second sub-pixels 7 in the corresponding first pixel repeating unit 9, and a third driving circuit 18 is electrically connected to the two third sub-pixels 8 in the corresponding first pixel repeating unit 9. It can be understood that the driving circuit in this embodiment is a one-to-many driving, that is, each driving circuit can drive multiple sub-pixels of the same color.

[0086] It can be understood that the one-to-many driving reduces the number of driving circuits in each driving circuit unit 15, which is beneficial to optimizing the wiring distribution in the transition region 2b and reducing the area of ​​the transition region 2b.

[0087] It can be understood that a plurality of sub-pixels displaying the same color in the first pixel repeating unit 9 can also be connected via the transparent wire 19 .

[0088] By comparing the diffraction simulation experiment, it can be seen that, compared with the prior art, the intensity of the secondary diffraction peak in the first display area 2 of the display panel 1 provided in the embodiment of the present application is reduced, and the secondary diffraction peak is more regular. In other words, the diffraction effect in the first display area 2 of the display panel 1 provided in the embodiment of the present application is significantly reduced, which is conducive to improving the influence of the diffraction effect on the imaging effect of the photosensitive device.

[0089] In the embodiment of the present application, pixel units obtained by deleting part of the first sub-pixels 6 (for example, green sub-pixels) on the basis of the pixel arrangement of the third pixel unit 13 and the fourth pixel unit 14 in the second display area 3 are used as the first pixel unit 10 and the second pixel unit 12 in the first display area 2, so that the pixel arrangement in the first display area 2 is optimized; on the one hand, the number of the first sub-pixels 6 in the first sub-display area 2a is smaller than the number of the first sub-pixels 6 in the second sub-display area 3a with the same area, which can effectively increase the area of ​​the light-transmitting area of ​​the first display area, which is beneficial to reducing the diffraction effect of the first display area; on the other hand, the first sub-pixel 6, the second sub-pixel 7, and the third sub-pixel 8 in the first display area are arranged according to REAL The arrangement of RGB is set, which effectively increases the area of ​​the light-transmitting area of ​​the first display area 2, which is conducive to reducing the diffraction effect of the first display area 2; on the other hand, by increasing the area of ​​the first sub-pixel 6 located in the first sub-display area 2a, the area of ​​the first sub-pixel 6 located in the first sub-display area 2a is larger than the area of ​​the first sub-pixel 6 located in the second sub-display area 3a, which is conducive to ensuring that the total area of ​​all first sub-pixels 6 located in the first sub-display area 2a is equivalent to the total area of ​​all first sub-pixels 6 located in the second sub-display area 3a of the same area, thereby ensuring that the display effect of the first display area 2 is not affected by the reduction in the number of first sub-pixels 6. Therefore, the embodiment of the present application can effectively reduce the diffraction effect of the first display area 2 on the basis of ensuring the display effect of the first display area 2, thereby improving the imaging effect of the photosensitive device.

[0090] like Figure 6 and Figure 7 As shown, the embodiment of the present application also provides a display panel, which is different from the aforementioned embodiment in that the arrangement position of the first sub-pixel 6 in the first display area 2 is different, which is specifically reflected in the different arrangement method of the second pixel unit 12 in the first pixel repeating unit 9 in the first display area 2.

[0091] In the embodiment of the present application, in the first direction, the distance between the center points of two adjacent first sub-pixels 6 located in the first display area 2 is greater than the distance between the center points of two adjacent first sub-pixels 6 located in the second display area 3, the distance between the center points of two adjacent second sub-pixels 7 located in the first display area 2 is equal to the distance between the center points of two adjacent second sub-pixels 7 located in the second display area 3, and the distance between the center points of two adjacent third sub-pixels 8 located in the first display area 2 is equal to the distance between the center points of two adjacent third sub-pixels 8 located in the second display area 3.

[0092] Moreover, in the second direction, the distance between the center points of two adjacent first sub-pixels 6 located in the first display area 2 is greater than the distance between the center points of two adjacent first sub-pixels 6 located in the second display area 3, the distance between the center points of two adjacent second sub-pixels 7 located in the first display area 2 is equal to the distance between the center points of two adjacent second sub-pixels 7 located in the second display area 3, and the distance between the center points of two adjacent third sub-pixels 8 located in the first display area 2 is equal to the distance between the center points of two adjacent third sub-pixels 8 located in the second display area 3.

[0093] It can be understood that the second sub-pixel 7 and the third sub-pixel 8 are arranged in the same manner in the first display area 2 and the second display area 3 .

[0094] Specifically, the number of first sub-pixels 6 arranged in the first direction in the first display area 2 can be reduced, and the number of first sub-pixels 6 arranged in the second direction in the first display area 2 can be reduced, so that the distance between the center points of two adjacent first sub-pixels 6 located in the first display area 2 in the first direction is greater than the distance between the center points of two adjacent first sub-pixels 6 located in the second display area 3, and the distance between the center points of two adjacent first sub-pixels 6 located in the first display area 2 in the second direction is greater than the distance between the center points of two adjacent first sub-pixels 6 located in the second display area 3.

[0095] It should be noted that in the embodiment of the present application, the first sub-pixel 6, the second sub-pixel 7, and the third sub-pixel 8 in the first display area 2 are still arranged according to the REAL RGB arrangement, and the first sub-pixel 6, the second sub-pixel 7, and the third sub-pixel 8 in the second display area 3 are still arranged according to the SPR arrangement.

[0096] Specifically, Figure 6 and Figure 7As shown, in the embodiment of the present application, the structure of the second pixel repetition unit 11 in the second display area 3 remains unchanged, specifically including the aforementioned third pixel unit 13 and fourth pixel unit 14; wherein the third pixel unit 13 is configured as a BGRG saw-shaped arrangement, and the fourth pixel unit 14 is configured as an RGBG saw-shaped arrangement.

[0097] Specifically, Figure 6 and Figure 7 As shown, in the embodiment of the present application, the structure of the first pixel unit 10 in the first pixel repetition unit 9 in the first display area 2 remains unchanged and is still configured as a BGR triangle arrangement; unlike the aforementioned embodiment, the second pixel unit 12 in the first pixel repetition unit 9 in the first display area 2 is configured as a RBG triangle arrangement, and the shape of the RBG triangle arrangement in the second pixel unit 12 is different from the shape of the BGR triangle arrangement in the first pixel unit 10.

[0098] In this embodiment, the pixel unit obtained by removing the last green sub-pixel (G) in the third pixel unit 13 can be used as the first pixel unit 10, and the pixel unit obtained by removing the first green sub-pixel (G) in the fourth pixel unit 14 can be used as the second pixel unit 12.

[0099] Specifically, the green sub-pixels in the multiple second pixel repeating units 11 of the second display area 3 are arranged in multiple rows and columns, and any two adjacent rows of green sub-pixels are arranged in a one-to-one correspondence, and any two adjacent columns of green sub-pixels are arranged in a one-to-one correspondence. The pixel arrangement of the multiple first pixel repeating units 9 in the first display area 2 can be obtained by individually removing the green sub-pixels in the multiple second pixel repeating units 11 within the same area.

[0100] Specifically, in the first display area 2, the green sub-pixels in the plurality of first pixel repeating units 9 are arranged in multiple rows and columns, any two adjacent rows of green sub-pixels are arranged alternately in sequence, and any two adjacent columns of green sub-pixels are arranged alternately in sequence. In the first direction, the ratio of the spacing between the center points of two adjacent green sub-pixels in the first display area 2 to the spacing between the center points of two adjacent green sub-pixels in the second display area 3 is 2; and in the second direction, the ratio of the spacing between the center points of two adjacent green sub-pixels in the first display area 2 to the spacing between the center points of two adjacent green sub-pixels in the second display area 3 is 2.

[0101] like Figure 6 and Figure 8As shown, in the first display area 2, three sub-pixels in any two second pixel units 12 adjacent in the first direction can also form a first pixel unit 10, so that the first display area 2 includes a plurality of first pixel units 10 arranged in an interlaced manner. Therefore, for the entire first display area 2, a plurality of first pixel units 10 arranged in a BGR triangle are arranged in multiple rows and columns, and any two adjacent rows of first pixel units 10 are arranged in an interlaced manner, and any two adjacent columns of first pixel units 10 are arranged in an interlaced manner.

[0102] like Figure 6 and Fig. 9 As shown, the first driving circuit 16, the second driving circuit 17 and the third driving circuit 18 in the driving circuit layer in the embodiment of the present application can be driven one-to-one or one-to-many, which will not be described in detail here.

[0103] The embodiments of the present application have the advantages described in the aforementioned embodiments, which will not be repeated here.

[0104] like Fig.10 As shown, an embodiment of the present application further provides a display device 20 , which includes a photosensitive device 21 and the display panel 1 described in the above embodiment; the photosensitive device 21 is arranged corresponding to the first display area 2 .

[0105] Specifically, the first display area 2 has high light transmittance and can provide a light path for the photosensitive device.

[0106] Specifically, the photosensitive device 21 includes a camera, an optical touch component, a fingerprint recognition sensor, and the like.

[0107] In the embodiment of the present application, the diffraction effect of the first display area 2 can be effectively reduced while ensuring the display effect of the first display area 2, thereby improving the imaging effect of the photosensitive device 21.
