Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of display panels, and more specifically, to a pixel arrangement structure, a display panel, and a display device. Background Art
[0002] OLED (Organic Light-Emitting Diode) belongs to a current-type organic light-emitting device, which is a phenomenon of luminescence caused by the injection and recombination of carriers, and the luminescence intensity is proportional to the injected current. Due to characteristics such as a wide color gamut, fast response speed, wide viewing angle, and flexibility, OLED display technology has become the mainstream product in the display field. With the development of this display technology, its application fields have also been greatly expanded.
[0003] The OLED display screen is composed of three sub-pixels of RGB. The RGB sub-pixels generally form an organic electroluminescent structure at the corresponding sub-pixel positions of the array substrate by using chemical vapor deposition technology to pass an organic material through a high-precision metal mask (FMM). And the higher the current density passing through the sub-pixel, the higher the luminescence intensity of the sub-pixel, but this will also lead to the attenuation of the life of the sub-pixel.
[0004] In order to improve the life of the sub-pixel, it is generally achieved by increasing the aperture ratio of the sub-pixel. By increasing the aperture ratio of the sub-pixel, the current density passing through the sub-pixel can be reduced while ensuring the same luminescence intensity.
[0005] However, when increasing the aperture ratio of the sub-pixel, there may be a phenomenon of mutual crosstalk between sub-pixels. Summary of the Invention

[0042] Explanation of reference numerals: 100, pixel unit; 101, first sub-pixel; 102, second sub-pixel; 103, third pixel; 200, substrate; VA, virtual pixel region Detailed implementation manners
[0043] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0044] Embodiment 1
[0045] Figure 1 Shows a pixel arrangement structure disclosed in an embodiment of the present application. Refer to Figure 1 As shown, the pixel arrangement structure includes a plurality of pixel units 100 arranged in an array, and each pixel unit 100 includes a first sub-pixel 101, a second sub-pixel 102, and a third sub-pixel 103.
[0046] Among them, a plurality of pixel units 100 correspond to a plurality of virtual pixel regions VA one by one, and the virtual pixel regions VA enclose the pixel units 100. That is, the regions occupied by the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 are all located within the corresponding virtual pixel regions VA. Moreover, the area where any sub-pixel is distributed within the corresponding virtual pixel region VA is determined according to the specified aperture ratio of the sub-pixel.
[0047] For example, when it is necessary to increase the aperture ratio of the first sub-pixel 101, the distribution area of the first sub-pixel 101 within the virtual pixel region VA is increased; when it is necessary to decrease the aperture ratio of the first sub-pixel 101, the distribution area of the first sub-pixel 101 within the virtual pixel region VA is decreased. In this way, the aperture ratio of any sub-pixel within the pixel unit 100 can be adjusted according to requirements.
[0048] Meanwhile, the second sub-pixel 102 and the third sub-pixel 103 are arranged around the first sub-pixel 101 within the virtual pixel region VA. Within the virtual pixel region VA, the second sub-pixel 102 and the third sub-pixel 103 are located outside the first sub-pixel 101. In this way, between two adjacent pixel units 100, the two first sub-pixels 101 are separated by the second sub-pixel 102 and the third sub-pixel 103, thereby reducing the occurrence of crosstalk between adjacent first sub-pixels 101. On the other hand, after defining the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 within the virtual pixel region VA, it is also possible to adjust the aperture ratio of any sub-pixel without changing the interval between adjacent pixel units 100, thereby further reducing the occurrence of crosstalk and improving the display effect of the display panel.
[0049] Therefore, when adjusting the aperture ratios of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103, it can be determined according to the shapes of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 and their respective distribution areas within the virtual pixel region VA, so as to meet the design requirements of different aperture ratio proportions.
[0050] For example, in one embodiment, referring to Figure 1 As shown, the first sub-pixel 101 is a blue sub-pixel, the second sub-pixel 102 is a red sub-pixel, the third sub-pixel 103 is a green sub-pixel, and each pixel unit 100 includes two third sub-pixels 103, that is, the quantity ratio among the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 is 1:1:2.
[0051] Meanwhile, the virtual pixel region VA is set as a square; two complete green sub-pixel units 100 within a square share the adjacent red sub-pixel and blue sub-pixel, and a virtual complete pixel is formed within a square region through the sub-pixel borrowing principle (SPR sub-pixel rendering technology).
[0052] Referring to Figure 1 As shown, the shape of the first sub-pixel 101 is set as an irregular pentagon, and the shapes of the second sub-pixel 102 and the third sub-pixel 103 are set as triangles.
[0053] Among them, the first sub-pixel 101 occupies the first vertex angle and the central region of the square virtual pixel region VA. Specifically, two sides of the first sub-pixel 101 are attached to the first vertex angle region, and then the first sub-pixel 101 extends along the reference line of the square and occupies most of the central region.
[0054] The second sub-pixel 102 occupies the second vertex region of the square virtual pixel region VA. Specifically, the right-angle sides of the second sub-pixel 102 are fitted to the second vertex region, and the hypotenuse faces the first sub-pixel 101.
[0055] The third sub-pixel 103 occupies the third and fourth vertex regions of the square virtual pixel region VA, and the third and fourth vertices are two adjacent vertices of the square. Specifically, the right-angle sides of the two third sub-pixels 103 are respectively fitted to the third vertex region and the fourth vertex region, and the hypotenuses of the two third sub-pixels 103 both face the first sub-pixel 101.
[0056] Moreover, the sides of the second sub-pixel 102 opposite to the first sub-pixel 101 are parallel to each other, and the sides of the third sub-pixel 103 opposite to the first sub-pixel 101 are parallel to each other.
[0057] After such a setting, within the square virtual pixel region VA, the second sub-pixel 102 and the third sub-pixel 103 are distributed around the first sub-pixel 101, surrounding the first sub-pixel 101. Furthermore, between two adjacent pixel units 100, the periphery of the first sub-pixel 101 is isolated by the second sub-pixel 102 and the second sub-pixel 102, thereby reducing the interference between two adjacent first sub-pixels 101.
[0058] In this embodiment, the aperture ratio among the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 is 5:1:2.
[0059] The first sub-pixel 101 is a blue sub-pixel. The larger the aperture ratio of the blue sub-pixel, the lower the current density passing through the blue sub-pixel can be, thereby reducing the lifetime attenuation of the blue sub-pixel.
[0060] For example, in one embodiment, as shown in Figure 2 the shape of the first sub-pixel 101 is an irregular pentagon, the shape of the second sub-pixel 102 is an irregular quadrilateral, and the shape of the third sub-pixel 103 is a triangle.
[0061] Among them, the first sub-pixel 101 occupies the first vertex and the central region of the square virtual pixel region VA. Specifically, two sides of the first sub-pixel 101 are fitted to the first vertex region, and then the first sub-pixel 101 extends along the reference line of the square and occupies most of the central region.
[0062] The second sub-pixel 102 occupies the second vertex region of the square virtual pixel region VA. Specifically, two sides of the second sub-pixel 102 are fitted to the second vertex region, the longer hypotenuse faces the first sub-pixel 101 and is parallel to the side of the first sub-pixel 101, and the shorter hypotenuse is in the same straight line as the short side of the first sub-pixel 101 located in the central region.
[0063] The third sub-pixel 103 occupies the third vertex and fourth vertex regions of the square virtual pixel region VA, and the third vertex and fourth vertex are two adjacent vertices of the square. Specifically, the right-angle sides of the two third sub-pixels 103 are respectively fitted to the third vertex region and the fourth vertex region, and the hypotenuses of the two third sub-pixels 103 both face the first sub-pixel 101, and the hypotenuses of the third sub-pixels 103 are parallel to the sides of the first sub-pixel 101 opposite thereto.
[0064] In this embodiment, the aperture ratio of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 is 5:2:2.
[0065] By changing the shape and area of the second sub-pixel 102, the aperture ratio of the second sub-pixel 102 can be correspondingly increased. The second sub-pixel 102 is a red sub-pixel. By increasing the aperture ratio of the red sub-pixel, the life attenuation of the red sub-pixel can be reduced.
[0066] For example, in one embodiment, referring to Figure 3 as shown, the shape of the first sub-pixel 101 is set as a rectangle with rounded corners at each vertex, and the second sub-pixel 102 and the third sub-pixel 103 are set as ellipses. The distribution positions of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 in the virtual pixel region VA are substantially the same as the pixel arrangement structure described above. However, making the shape of the first sub-pixel 101 a rectangle with rounded corners at each vertex and making the shapes of the second sub-pixel 102 and the third sub-pixel 103 ellipses can further increase the areas of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103, and thus increase the aperture ratios of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103.
[0067] In one embodiment, the virtual pixel region VA can also be a rhombus.
[0068] Embodiment 2

The plurality of pixel units 100 can adopt the pixel arrangement structure provided in Embodiment 1 of the present application.
[0070] By adopting this pixel arrangement structure, the phenomenon of mutual crosstalk between the sub-pixels of adjacent pixel units 100 can be reduced, ensuring the display effect of the display panel.

The mask may include a first mask for forming the first sub-pixel 101, a second mask for forming the second sub-pixel 102, and a third mask for forming the third sub-pixel 103.
