[0029] 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.

[0030] Reference Figure 1 As shown, it is a schematic diagram of a pixel arrangement structure. The pixel arrangement structure includes a plurality of pixels P arranged in an array along a first direction X and a second direction Y, and the first direction X is perpendicular to the second direction Y. Each pixel P includes a red sub-pixel R, a blue sub-pixel B, and a green sub-pixel G. The area of ​​the blue sub-pixel B, the area of ​​the green sub-pixel G, and the area of ​​the red sub-pixel R decrease in sequence.

[0031] In one pixel, the distance between the red sub-pixel R and the green sub-pixel G is equal to PDL_gap, and the distance between the blue sub-pixel B and the red sub-pixel R and the distance between the blue sub-pixel B and the green sub-pixel G are both greater than PDL_gap. In two adjacent pixels in the first direction X, the distance between the green sub-pixel G with a larger area and the blue sub-pixel B is equal to PDL_gap, while the distance between the red sub-pixel R and the blue sub-pixel B with a smaller area is greater than PDL_gap. PDL_gap may be the minimum distance between two adjacent pixel openings of the pixel definition layer.

[0032] for Figure 1 In the design of the pixel arrangement structure shown, the aperture ratio of the red sub-pixel R, the blue sub-pixel B and the green sub-pixel G is relatively small, and the current density required for each sub-pixel to achieve the target sub-pixel current is larger, resulting in a shorter life of the display panel including the pixel arrangement structure.

[0033] In view of the problem that the aperture ratios of the red sub-pixel R, the blue sub-pixel B, and the green sub-pixel G are relatively small, an embodiment of the present application provides a pixel arrangement structure 100 to at least partially solve the above problem.

[0034] Reference Figure 2 and Figure 3 As shown, an embodiment of the present application provides a pixel arrangement structure 100. The pixel arrangement structure 100 can be applied to at least one of an organic light emitting diode display panel 300 and a quantum dot display panel 300, but is not limited thereto.

[0035] The pixel arrangement structure 100 includes a plurality of pixel repeating units 20 arranged in an array along a first direction X and a second direction Y, wherein the first direction X intersects the second direction Y. The pixel repeating unit 20 includes two pixels P arranged along the first direction X. Each pixel P includes a first sub-pixel 11, a second sub-pixel 12, and a third sub-pixel 13 located at three vertices of a virtual triangle S, respectively. The first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 emit light of three different colors, respectively. In the pixel repeating unit 20, the second sub-pixel 12 of one pixel P is adjacent to the third sub-pixel 13 of another pixel P in the first direction X, and the first sub-pixel 11 of one pixel P is adjacent to one of the second sub-pixel 12 and the third sub-pixel 13 of another pixel P in the first direction X.

[0036] In the pixel arrangement structure 100 of some embodiments of the present application, the above-mentioned pixel arrangement structure 100 is used to reduce the minimum spacing between the second sub-pixel 12 of a pixel P and the third sub-pixel 13 of another pixel P, and the minimum spacing between the first sub-pixel 11 of a pixel P and one of the second sub-pixel 12 and the third sub-pixel 13 of another pixel P. When the layout space occupied by each pixel P remains unchanged, the minimum spacing between the sub-pixels in the two pixels P is reduced, which can provide more space for setting sub-pixels, so that the area of ​​at least one sub-pixel in the two pixels P can be increased. When the target pixel current of the sub-pixel is constant, the area of ​​at least one sub-pixel is increased, which is conducive to reducing the current density of the driving current of at least one sub-pixel and extending the life of the display panel 300.

[0037] It should be noted that if the second sub-pixel 12 of a pixel P is adjacent to the second sub-pixel 12 of another pixel P in the first direction X, and the first sub-pixel 11 of a pixel P is adjacent to the third sub-pixel 13 of another pixel P in the first direction X, the minimum spacing between the first sub-pixel 11 of a pixel P and the third sub-pixel 13 of another pixel P needs to be increased. By adopting some embodiments of the present application described above, the minimum spacing between the second sub-pixel 12 of a pixel P and the third sub-pixel 13 of another pixel P and the minimum spacing between the first sub-pixel 11 of a pixel P and the second sub-pixel 12 of another pixel P can be reduced at the same time.

[0038] In some embodiments, the first direction X is perpendicular to the second direction Y. It is understood that the angle between the first direction X and the second direction Y may also be an acute angle.

[0039] In some embodiments, in one pixel P, the center of one of the second sub-pixel 12 and the third sub-pixel 13 and the center of the first sub-pixel 11 are located on the first virtual side L1, and the first virtual side L1 intersects the first direction X and the second direction Y. In another pixel P, the center of the third sub-pixel 13 and the center of the second sub-pixel 12 are located on the second virtual side L2. The second virtual side L2 is adjacent to the first virtual side L1 and tilted toward the first virtual side L1, and intersects the first direction X and the second direction Y. In this way, not only the minimum spacing between the second sub-pixel 12 of one pixel P and the third sub-pixel 13 of another pixel P and the minimum spacing between the first sub-pixel 11 of one pixel P and one of the second sub-pixel 12 and the third sub-pixel 13 of another pixel P are reduced, but also the minimum spacing between the first sub-pixel 11 in one pixel P and the other of the second sub-pixel 12 and the third sub-pixel 13 of another pixel P is reduced, which can provide more space for setting sub-pixels. The sum of the areas of multiple sub-pixels in two pixels P can be larger, further reducing the current density of the driving current of the sub-pixels, thereby further extending the life of the display panel 300.

[0040] Exemplarily, in a virtual triangle S, the line between the center of one of the second sub-pixel 12 and the third sub-pixel 13 and the center of the first sub-pixel 11 constitutes the first virtual side L1 of the virtual triangle S, the center of the third sub-pixel 13 and the center of the second sub-pixel 12 constitute the second virtual side L2 of the virtual triangle S, and the center of the other of the second sub-pixel 12 and the third sub-pixel 13 and the center of the first sub-pixel 11 constitute the third virtual side L3 of the virtual triangle S.

[0041] In some embodiments, reference Figure 1 As shown, the two second virtual edges L2 intersect each other. This helps to reduce the spacing between sub-pixels in two pixels P and provide more space for arranging sub-pixels.

[0042] In some embodiments, in a pixel P, the minimum distance between any two of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is the first distance d1, that is, the spacing between any two sub-pixels in a pixel P is equal. When the area occupied by each pixel P remains unchanged and the spacing between two sub-pixels is adjusted to the minimum spacing allowed in the process, the layout space of the first sub-pixel 11 to the third sub-pixel 13 in a pixel P can be maximized, that is, the sum of the areas of the first sub-pixel 11 to the third sub-pixel 13 in a pixel P can be maximized. The area of ​​at least one of the first sub-pixel 11 to the third sub-pixel 13 can be further increased, and the current density of the driving current of at least one of the first sub-pixel 11 to the third sub-pixel 13 can be further reduced, thereby further extending the life of the display panel 300.

[0043] In the present application, the minimum distance between two sub-pixels is equal to the minimum distance between the edges of the two sub-pixels.

[0044] In some embodiments, in a pixel repeating unit 20, the minimum distance between the first sub-pixel 11 of a pixel P and the second sub-pixel 12 of another pixel P is the first distance d1, and the minimum distance between the first sub-pixel 11 of a pixel P and the third sub-pixel 13 of another pixel P is the first distance d1. In this way, the minimum distances between the first sub-pixel 11 of a pixel P and the second sub-pixel 12 and the third sub-pixel 13 of another pixel P are equal. When the area occupied by the two pixels P remains unchanged, when the minimum distance between the first sub-pixel 11 of a pixel P and the second sub-pixel 12 and the third sub-pixel 13 of another pixel P is adjusted to the minimum spacing allowed in the process, there is more space in the two pixels P to set multiple sub-pixels. The sum of the areas of the multiple sub-pixels in the two pixels P is larger, which further reduces the current density of the driving current of the sub-pixels, thereby further extending the life of the display panel 300.

[0045] In some embodiments, in one pixel repeating unit 20, the minimum distance between the second sub-pixel 12 of one pixel P and the third sub-pixel 13 of another pixel P adjacent to each other in the first direction X is the second distance d2, and the second distance d2 is greater than the first distance d1. In this way, the minimum distance between the first sub-pixel 11 of one pixel P and the second sub-pixel 12 of another pixel P can be smaller.

[0046] In some embodiments, in two adjacent pixel repeating units 20 in the second direction Y, the minimum distance between a first sub-pixel 11 and a second sub-pixel 12 respectively located in the two adjacent pixel repeating units 20 is the first distance d1, and the minimum distance between a first sub-pixel 11 and a third sub-pixel 13 respectively located in the two adjacent pixel repeating units 20 is equal to the first distance d1. In this way, the minimum distance between a first sub-pixel 11 and a second sub-pixel 12 adjacent to the two pixel repeating units 20 is equal to the minimum distance between a first sub-pixel 11 and a third sub-pixel 13 adjacent to the two pixel repeating units 20. When the two minimum spacings are adjusted to the minimum spacing allowed by the process, there is more space for sub-pixels to be arranged in the two adjacent pixel repeating units 20. The sum of the areas of the multiple sub-pixels in the two adjacent pixel repeating units 20 is larger, which further reduces the current density of the driving current of the sub-pixels, thereby further extending the life of the display panel 300.

[0047] In some embodiments, in two adjacent pixel repeating units 20 in the second direction Y, the minimum distance between a second sub-pixel 12 and a third sub-pixel 13 respectively located in the two adjacent pixel repeating units 20 is equal to the second distance d2, and the second distance d2 is greater than the first distance d1. In this way, the minimum distance between a first sub-pixel 11 and a second sub-pixel 12 adjacent to the two pixel repeating units 20, and the minimum distance between a first sub-pixel 11 and a third sub-pixel 13 adjacent to the two pixel repeating units 20 can be smaller.

[0048] In some embodiments, the first distance d1 may be the minimum distance between two adjacent pixel P openings in the pixel definition layer 31. The minimum distance between two pixel P openings is required to reduce the risk of sub-pixel color mixing in two adjacent pixel P openings. In some embodiments, the first distance d1 may be 15 microns to 25 microns. Exemplarily, the first distance d1 may be 15 microns, 18 microns, 20 microns, 22 microns, 24 microns, or 25 microns.

[0049] In some embodiments, at least one of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is circular in shape. In this way, the color symmetry of the pixel arrangement structure 100 when emitting light for display is improved, and the problem of color separation is improved.

[0050] In an exemplary embodiment, the first sub-pixel 11 , the second sub-pixel 12 , and the third sub-pixel 13 are all circular in shape, which further improves color symmetry and alleviates the problem of color separation.

[0051] In other embodiments, at least one of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 may also be in the shape of at least one of a polygon, an ellipse and an irregular shape. The polygon includes a quadrilateral, a pentagon, a hexagon and an octagon.

[0052] In some embodiments, the first sub-pixel 11 is a blue sub-pixel, one of the second sub-pixel 12 and the third sub-pixel 13 is a red sub-pixel, and the other of the second sub-pixel 12 and the third sub-pixel 13 is a green sub-pixel. The area of ​​the blue sub-pixel is larger than the area of ​​the green sub-pixel, and the area of ​​the green sub-pixel is larger than the area of ​​the red sub-pixel. In this way, the pixel arrangement structure 100 can emit red light, blue light, and green light. In addition, the larger area of ​​the blue sub-pixel and the larger area of ​​the green sub-pixel can also extend the working life of the two.

[0053] In some embodiments, the ratio of the area of ​​the blue sub-pixel to the area of ​​the red sub-pixel is greater than 2 and less than or equal to 3, and the ratio of the area of ​​the green sub-pixel to the area of ​​the red sub-pixel is greater than 1 and less than or equal to 2.5. In this way, the area of ​​the blue sub-pixel and the area of ​​the green sub-pixel are ensured to be large while taking into account the area of ​​the red sub-pixel, thereby ensuring the optimal life of a pixel P.

[0054] In some embodiments, reference Figure 2 As shown, the first direction X may be a row direction, and the second direction Y may be a column direction. The first sub-pixel 11 is a blue sub-pixel, the second sub-pixel 12 is a red sub-pixel, and the third sub-pixel 13 is a green sub-pixel.

[0055] In some embodiments, reference Figure 2 As shown, two first sub-pixels 11 in one pixel repeating unit 20 are staggered in the first direction X and the second direction Y. In this way, the distance between the first sub-pixel 11 and the other sub-pixels can be reduced.

[0056] In some embodiments, reference Figure 2 As shown, two second sub-pixels 12 in one pixel repeating unit 20 are staggered in the first direction X and the second direction Y. In this way, the distance between the second sub-pixel 12 and other sub-pixels can be reduced.

[0057] In some embodiments, reference Figure 2 As shown, two third sub-pixels 13 in one pixel repeating unit 20 are staggered in the first direction X and the second direction Y. In this way, the distance between the third sub-pixel 13 and other sub-pixels can be reduced.

[0058] In other embodiments, referring to Figure 3 As shown, the first direction X may be a row direction, and the second direction Y may be a column direction. The first sub-pixel 11 is a blue sub-pixel, the second sub-pixel 12 is a green sub-pixel, and the third sub-pixel 13 is a red sub-pixel.

[0059] As shown in Table 1, it is Figure 1 The pixel arrangement structure 100 is Figure 2 The relevant parameters of the pixel arrangement structure 100 are shown in Table 1. Among them, PDL_gap in Table 1 is Figure 2 The first distance d1 is also Figure 1 The distance between the red sub-pixel and the green sub-pixel. The radius of the circle is the radius of the sub-pixel. The aperture ratio is the aperture ratio of the sub-pixel.

[0060]

[0061] for Figure 2In the pixel arrangement structure 100 shown, when the first distance d1 is equal to the minimum distance PDL_gap between the openings of two adjacent pixels P, the distances between the blue sub-pixel and all the surrounding red sub-pixels and green sub-pixels are equal to PDL_gap, and the distance between the red sub-pixel and the green sub-pixel in a pixel P is equal to PDL_gap. Moreover, the distance between the red sub-pixel and the green sub-pixel in adjacent pixels is greater than PDL_gap. These designs can provide more space for setting the blue sub-pixel, the red sub-pixel and the green sub-pixel, significantly increasing the radius of the three sub-pixels. When the radius of the three sub-pixels increases, their aperture ratios all increase, making the total aperture ratio higher than 1.17mm. Figure 1 The structure shown in FIG. 3 is improved by 43%. When the aperture ratio of the three sub-pixels is increased, the current density of the three sub-pixels is reduced, thereby improving the life of the display panel 300. Figure 1 The structure shown corresponds to a lifespan improvement of 53%.

[0062] In some other embodiments, reference Figures 4 to 7 As shown, the first direction X may be a column direction, and the second direction Y may be a row direction.

[0063] In some other embodiments, reference Figure 4 and Figure 6 As shown, when the first direction X is the column direction and the second direction Y is the row direction, the first sub-pixel 11 is a blue sub-pixel, the second sub-pixel 12 is a red sub-pixel, and the third sub-pixel 13 is a green sub-pixel.

[0064] In some other embodiments, reference Figure 5 and Figure 7 As shown, when the first direction X is the column direction and the second direction Y is the row direction, the first sub-pixel 11 is a blue sub-pixel, the second sub-pixel 12 is a green sub-pixel, and the third sub-pixel 13 is a red sub-pixel.

[0065] Based on the same inventive concept, Figure 8 As shown, the embodiment of the present application further provides a display panel 300. The display panel 300 includes a light emitting device layer 30. The light emitting device layer 30 includes the pixel arrangement structure 100 of any of the above embodiments.

[0066] The light-emitting device layer 30 includes a pixel definition layer 31 and a light-emitting layer 301. The pixel definition layer 31 includes a first pixel opening 311, a second pixel opening 312, and a third pixel opening 313 that are spaced apart. A dam is provided between any two of the first pixel opening 311, the second pixel opening 312, and the third pixel opening 313. The light-emitting layer 301 includes the plurality of pixels P described above. The first sub-pixel 11 is provided in the first pixel opening 311. The second sub-pixel 12 is provided in the second pixel opening 312. The third sub-pixel 13 is provided in the third pixel opening 313. The first sub-pixel 11 to the third sub-pixel 13 all include organic light-emitting materials.

[0067] The light emitting device layer 30 also includes an anode layer 302. The anode layer 302 includes a first anode, a second anode, and a third anode. The anode layer 302 is located below the pixel definition layer 31. The first pixel opening 311 exposes the first anode, and the first sub-pixel 11 is located on the first anode. The second pixel opening 312 exposes the second anode, and the second sub-pixel 12 is located on the second anode. The third sub-pixel 13 opening exposes the third anode, and the third sub-pixel 13 is located on the third anode.

[0068] The light emitting device layer 30 further includes a cathode layer 303 . The cathode layer 303 covers the pixel definition layer 31 and the light emitting layer 301 .

[0069] In some embodiments, the display panel 300 further includes a color filter layer 32. The color filter layer 32 is overlapped with the light-emitting device layer 30 in the third direction, and includes a first filter unit 321, a second filter unit 322, and a third filter unit 323. The first filter unit overlaps with the first sub-pixel 11, the second filter unit overlaps with the second sub-pixel 12, and the third filter unit overlaps with the third sub-pixel 13. The third direction Z intersects with the first direction X and the second direction Y. The color filter layer 32 has a greater transmittance to the light emitted by the light-emitting device layer 30. When the display panel 300 displays a certain brightness, the transmittance is greater, which can reduce the driving current of the light-emitting device layer 30, thereby reducing the power consumption of the display panel 300 and improving the device life and anti-burning ability of the display panel 300.

[0070] The color of the first filter unit is the same as the color of the light emitted by the first sub-pixel 11, so as to ensure that the light emitted by the first sub-pixel 11 can pass through the first filter unit. The color of the light emitted by the second filter unit is the same as the color of the light emitted by the second sub-pixel 12, so as to ensure that the light emitted by the second sub-pixel 12 can pass through the second filter unit. The color of the light emitted by the third filter unit is the same as the color of the light emitted by the third sub-pixel 13, so as to ensure that the light emitted by the third sub-pixel 13 can pass through the third filter unit.

[0071] Exemplarily, when the first to third sub-pixels 11 to 13 are blue, red and green sub-pixels respectively, the first filter unit, the second filter unit and the third filter unit are respectively one of the blue filter unit, the red filter unit and the green filter unit.

[0072] In some embodiments, the third direction Z is perpendicular to both the first direction X and the second direction Y.

[0073] In some other embodiments, the display panel 300 may further include a circular polarizer, and the circular polarizer is stacked with the light emitting device layer 30 in the third direction, so as to improve the contrast of the display panel 300 during display.

[0074] In some embodiments, the display panel 300 may further include a thin film encapsulation layer 33, which covers the light emitting device layer 30 to protect the light emitting device layer 30. The thin film encapsulation layer 33 may include two organic encapsulation layers and an inorganic encapsulation layer between the two organic encapsulation layers.

[0075] In some embodiments, the display panel 300 may further include a driving circuit layer 34, wherein the driving circuit layer 34 includes a pixel driving circuit. The pixel driving circuit is used to drive the pixels to emit light.

[0076] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0077] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
