[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0030] Reference Figure 1 The diagram shows a schematic representation of a pixel arrangement structure. The pixel arrangement structure includes multiple pixels P arranged in an array along a first direction X and a second direction Y, with the first direction X 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 areas of the blue sub-pixel B, the green sub-pixel G, and the red sub-pixel R decrease sequentially.
[0031] Within a pixel, the distance between a red subpixel R and a green subpixel G is equal to PDL_gap, while the distances between a blue subpixel B and a red subpixel R, as well as between a blue subpixel B and a green subpixel G, are both greater than PDL_gap. In the first direction X, between two adjacent pixels, the distance between a larger green subpixel G and a blue subpixel B is equal to PDL_gap, while the distance between a smaller red subpixel R and a blue subpixel B is greater than PDL_gap. PDL_gap can be the minimum distance between the openings of two adjacent pixels in the pixel definition layer.
[0032] for Figure 1 The pixel arrangement structure shown has a smaller aperture ratio for the red sub-pixel R, blue sub-pixel B, and green sub-pixel G. Each sub-pixel requires a larger current density to achieve the target sub-pixel current, resulting in a shorter lifespan for the display panel including the pixel arrangement structure.
[0033] To address the issue of low aperture ratios in the red sub-pixel R, blue sub-pixel B, and green sub-pixel G, this application provides a pixel arrangement structure 100 to at least partially solve the aforementioned problem.
[0034] Reference Figure 2 and Figure 3 As shown, this 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 comprises a plurality of pixel repeating units 20 arranged in a first direction X and a second direction Y, the first direction X and the second direction Y being perpendicular to each other. The pixel repeating unit 20 comprises two pixels P arranged in the first direction X. Each pixel P comprises 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 and the third sub-pixel 13 of another pixel P are adjacent in the first direction X, and 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 adjacent in the first direction X.
[0036] In the pixel arrangement structure 100 of some embodiments of the present application, the pixel arrangement structure 100 described above is advantageous in reducing the minimum distance between the second sub-pixel 12 of one pixel P and the third sub-pixel 13 of another pixel P, and the minimum distance 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. In the case where the layout space occupied by each pixel P remains unchanged, the reduction of the minimum distance between the sub-pixels in the two pixels P can provide more space for arranging the sub-pixels, so that the area of at least one sub-pixel in the two pixels P can be increased. In the case where the target pixel current of the sub-pixel remains unchanged, the increase of the area of the at least one sub-pixel is advantageous in reducing the current density of the driving current of the at least one sub-pixel, and prolonging the service life of the display panel 300.
[0037] It should be noted that if the second sub-pixel 12 of one pixel P and the second sub-pixel 12 of another pixel P are adjacent in the first direction X, and the first sub-pixel 11 of one pixel P and the third sub-pixel 13 of another pixel P are adjacent in the first direction X, the minimum distance between the first sub-pixel 11 of one pixel P and the third sub-pixel 13 of another pixel P needs to be increased. The above-mentioned embodiments of the present application can simultaneously reduce the minimum distance between the second sub-pixel 12 of one pixel P and the third sub-pixel 13 of another pixel P, and the minimum distance between the first sub-pixel 11 of one pixel P and the second sub-pixel 12 of another pixel P.
[0038] In some embodiments, the first direction X and the second direction Y are perpendicular. It can be understood that the included angle between the first direction X and the second direction Y can 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 a first virtual edge L1, the first virtual edge 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 a second virtual edge L2. The second virtual edge L2 is adjacent to the first virtual edge L1 and is inclined towards the first virtual edge L1, and intersects the first direction X and the second direction Y. In this way, not only the minimum distance between the second sub-pixel 12 of one pixel P and the third sub-pixel 13 of another pixel P and the minimum distance 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 distance between the first sub-pixel 11 of 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 arranging the sub-pixels. The sum of the areas of the plurality of sub-pixels in the two pixels P can be larger, further reducing the current density of the driving current of the sub-pixels, and further prolonging the service life of the display panel 300.
[0040] Exemplarily, in one 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 a first virtual edge L1 of the virtual triangle S, the center of the third sub-pixel 13 and the center of the second sub-pixel 12 constitute a second virtual edge 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 a third virtual edge L3 of the virtual triangle S.
[0041] In some embodiments, referring to Figure 1 As shown, the two second virtual edges L2 intersect. In this way, it is beneficial to reduce the distance between the sub-pixels in the two pixels P and provide more space for arranging the sub-pixels.
[0042] In some embodiments, in one 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 a first distance d1, that is, the distance between any two sub-pixels in one pixel P is equal. When the distance between the two sub-pixels is adjusted to the minimum distance allowed by the process under the condition that the area occupied by each pixel P is unchanged, the arrangement space of the first sub-pixel 11 to the third sub-pixel 13 in one pixel P can be maximum, that is, the sum of the areas of the first sub-pixel 11 to the third sub-pixel 13 in one pixel P can be maximum. The area of at least one of the first sub-pixel 11 to the third sub-pixel 13 can be further increased, further reducing the current density of the driving current of at least one of the first sub-pixel 11 to the third sub-pixel 13, and further prolonging the service 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 one pixel repeating unit 20, the minimum distance between the first sub-pixel 11 of one 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 one pixel P and the third sub-pixel 13 of another pixel P is 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 and the third sub-pixel 13 of another pixel P is equal. When the minimum distance between the first sub-pixel 11 of one pixel P and the second sub-pixel 12 and the third sub-pixel 13 of another pixel P is adjusted to the minimum pitch allowed by the process, there is more space in the two pixels P to arrange multiple sub-pixels. The sum of the areas of the multiple sub-pixels in the two pixels P is larger, further reducing the current density of the driving current of the sub-pixels, and further prolonging 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 adjacent in the first direction X and the third sub-pixel 13 of another pixel P is the second distance d2, which is greater than the first distance d1. In this way, it is beneficial for the minimum distance between the first sub-pixel 11 of one pixel P and the second sub-pixel 12 of another pixel P to be smaller.
[0046] In some embodiments, in two adjacent pixel repeating units 20 in the second direction Y, the minimum distance between one first sub-pixel 11 and one second sub-pixel 12 located in the two pixel repeating units 20 respectively is the first distance d1, and the minimum distance between one first sub-pixel 11 and one third sub-pixel 13 located in the two pixel repeating units 20 respectively is equal to the first distance d1. In this way, the minimum distance between one first sub-pixel 11 and one second sub-pixel 12 in the two pixel repeating units 20 is equal to the minimum distance between one first sub-pixel 11 and one third sub-pixel 13 in the two pixel repeating units 20. When the two minimum pitches are adjusted to the minimum pitch allowed by the process, there is more space in the two adjacent pixel repeating units 20 to arrange sub-pixels. The sum of the areas of the multiple sub-pixels in the two adjacent pixel repeating units 20 is larger, further reducing the current density of the driving current of the sub-pixels, and further prolonging the life of the display panel 300.
[0047] In some embodiments, the minimum distance between the first sub-pixel 11 and the second sub-pixel 12 in the adjacent one of the two pixel repeating units 20 is equal to a 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 and the second sub-pixel 12 in the adjacent one of the two pixel repeating units 20 and the minimum distance between the first sub-pixel 11 and the third sub-pixel 13 in the adjacent one of the two pixel repeating units 20 can be smaller.
[0048] In some embodiments, the first distance d1 can be the minimum distance between the two adjacent pixel P openings in the pixel defining layer 31. The minimum distance between the two adjacent pixel P openings needs to reduce the risk of sub-pixel color mixing in the two adjacent pixel P openings. In some embodiments, the first distance d1 can be 15-25 microns. For example, the first distance d1 can be 15 microns, 18 microns, 20 microns, 22 microns, 24 microns, or 25 microns.
[0049] In some embodiments, the shape of at least one of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is circular. In this way, the color symmetry when the pixel arrangement structure 100 emits light for display is improved, and the color separation problem is improved.
[0050] In an exemplary embodiment, the shapes of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are all circular, further improving the color symmetry and improving the color separation problem.
[0051] In other embodiments, the shape of at least one of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 can also be at least one of a polygon, an ellipse, and an irregular shape. The polygon includes a quadrilateral, a pentagon, a hexagon, an octagon, and the like.
[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 greater than the area of the green sub-pixel, and the area of the green sub-pixel is greater 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. Moreover, the areas of the blue sub-pixel and the green sub-pixel are larger, which can also prolong the service 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 areas of the blue sub-pixel and the green sub-pixel are ensured to be large, while the area of the red sub-pixel is also considered, to ensure the best service life of a pixel P.
[0054] In some embodiments, referring to FIG. 1, a first direction X can be a row direction, and a second direction Y can be a column direction. A first sub-pixel 11 is a blue sub-pixel, a second sub-pixel 12 is a red sub-pixel, and a third sub-pixel 13 is a green sub-pixel. Figure 2
[0055] In some embodiments, referring to FIG. 2, 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 spacing between the first sub-pixel 11 and other sub-pixels is reduced. Figure 2
[0056] In some embodiments, referring to FIG. 3, 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 spacing between the second sub-pixel 12 and other sub-pixels is reduced. Figure 2
[0057] In some embodiments, referring to FIG. 4, 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 spacing between the third sub-pixel 13 and other sub-pixels is reduced. Figure 2 In other embodiments, referring to FIG. 5, a first direction X can be a row direction, and a second direction Y can be a column direction. A first sub-pixel 11 is a blue sub-pixel, a second sub-pixel 12 is a green sub-pixel, and a third sub-pixel 13 is a red sub-pixel.
[0058] Figure 3 As shown in Table 1, which is related parameters of the pixel arrangement structure 100 shown in FIG. 6 and the pixel arrangement structure 100 shown in FIG. 7. In Table 1, PDL_gap is the first distance d1 in FIG. 6, which is also the spacing between the red sub-pixel and the green sub-pixel in FIG. 7. The circular radius is the radius of the sub-pixel. The aperture ratio is the aperture ratio of the sub-pixel.
[0059] Figure 1 Figure 2 Figure 2 Figure 1
[0060]
[0061] For the pixel arrangement structure 100 shown in FIG. 6, 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 areas of the blue sub-pixel and the green sub-pixel are ensured to be large, while the area of the red sub-pixel is also considered, to ensure the best service life of a pixel P. Figure 2 The pixel arrangement structure 100 shown in the figure, when the first distance d1 is equal to the minimum distance PDL_gap between the openings of two adjacent pixels P, the distance between the blue sub-pixel and all the surrounding red sub-pixels and green sub-pixels is equal to PDL_gap, and the distance between the red sub-pixel and the green sub-pixel in one 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 arranging the blue sub-pixel, the red sub-pixel and the green sub-pixel, and significantly increase the radii of the three sub-pixels. In the case of increased radii of the three sub-pixels, the aperture ratios of the three sub-pixels are increased, so that the total aperture ratio is increased by 43% compared with the structure shown in the figure. Figure 1 The structure shown in the figure increases the aperture ratios of the three sub-pixels. In the case of increased aperture ratios of the three sub-pixels, the current densities of the three sub-pixels are reduced, so that the lifetime of the display panel 300 is increased by 53% compared with the structure shown in the figure. Figure 1 The structure shown in the figure increases the aperture ratios of the three sub-pixels. In the case of increased aperture ratios of the three sub-pixels, the current densities of the three sub-pixels are reduced, so that the lifetime of the display panel 300 is increased by 53% compared with the structure shown in the figure.
[0062] In yet some embodiments, referring to Figures 4 to 7 The first direction X can be the column direction and the second direction Y can be the row direction.
[0063] In yet some embodiments, referring to Figure 4 The first direction X can be the column direction and the second direction Y can be the row direction. Figure 6 In the case where 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 yet some embodiments, referring to Figure 5 The first direction X can be the column direction and the second direction Y can be the row direction. Figure 7 In the case where 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, referring to Figure 8 The present embodiments also provide a display panel 300. The display panel 300 comprises a light-emitting device layer 30. The light-emitting device layer 30 comprises 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 arranged at intervals. A dam is arranged 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 a plurality of pixels P described above. The first sub-pixel 11 is arranged in the first pixel opening 311. The second sub-pixel 12 is arranged in the second pixel opening 312. The third sub-pixel 13 is arranged in the third pixel opening 313. The first sub-pixel 11 to the third sub-pixel 13 each include an organic light-emitting material.
[0067] The light-emitting device layer 30 further 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 pixel opening 313 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 stacked with the light-emitting device layer 30 in a third direction Z, and includes a first filter unit 321, a second filter unit 322, and a third filter unit 323, the first filter unit overlaps the first sub-pixel 11, the second filter unit overlaps the second sub-pixel 12, and the third filter unit overlaps the third sub-pixel 13, the third direction Z intersects the first direction X and the second direction Y. The color filter layer 32 has a greater transmittance for light emitted by the light-emitting device layer 30. When the display panel 300 displays a certain brightness, the greater transmittance can reduce the driving current of the light-emitting device layer 30, thereby reducing the power consumption of the display panel 300, improving the device life and burn-in resistance 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 to ensure that the light emitted by the first sub-pixel 11 can pass through the first filter unit. The color of the second filter unit is the same as the color of the light emitted by the second sub-pixel 12 to ensure that the light emitted by the second sub-pixel 12 can pass through the second filter unit. The color of the third filter unit is the same as the color of the light emitted by the third sub-pixel 13 to ensure that the light emitted by the third sub-pixel 13 can pass through the third filter unit.
[0071] Exemplarily, in a case where the first sub-pixel 11 to the third sub-pixel 13 are blue sub-pixels, red sub-pixels and green sub-pixels respectively, the first filter unit, the second filter unit and the third filter unit are one of a blue filter unit, a red filter unit and a green filter unit respectively.
[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 can further include a circular polarizer, which is stacked with the light-emitting device layer 30 in the third direction. In this way, the contrast ratio of the display panel 300 when displaying is improved.
[0074] In some embodiments, the display panel 300 can further include a thin film encapsulation layer 33, which covers the light-emitting device layer 30 to protect the light-emitting device layer 30.
