Description

Technical Field

[0001] The present invention belongs to the technical field of display elements, and in particular relates to a pixel arrangement structure, a display panel and a display device. Background Art

[0002] For example, the display device of the display screen is an important human-computer interaction medium. From smart watches / bracelets to mobile phones, computers and dedicated service terminals, to large display screens for demonstrations, conference displays and advertising screens and other smart devices, all need to use display screens as human-computer interaction media.

[0003] Currently, high-density, small-pitch LED, Mini LED, and Micro LED display technologies have all become popular technologies for new high-definition LED displays, and the product's display effect has become a common focus for users and the industry. Generally speaking, without considering brightness, contrast, stability, and uniformity, the factors affecting the image clarity of high-density LED displays mainly include image spatial resolution, image display layer resolution, pixel optical crosstalk, and pixel edge fusion. Among them, image spatial resolution is equivalent to the arrangement density of LED pixels in LED displays. Therefore, the pixel arrangement structure has a decisive influence on the brightness, response speed, color quality, and service life of the display. To increase the pixel arrangement density, the industry has adopted virtual pixel technology. Virtual pixels use software algorithms to control the light-emitting chip of each color to act as a sub-pixel and ultimately participate in the imaging of multiple adjacent pixels. This allows for a higher resolution with fewer lamps, thereby improving the display resolution through sub-pixel multiplexing.

[0004] However, the pixel arrangement structure currently using virtual pixel technology, on the one hand, the layout of multiple sub-pixels in the pixel unit is not scientific and reasonable, resulting in limited display effects produced by virtual pixels and a small degree of improvement in display screen resolution; on the other hand, for existing rectangular pixel units, while adopting virtual pixel technology, it brings about the technical problem of colored lines or bright and dark lines on the four edges of the rectangular pixel unit, resulting in a reduction in display effect.

[0005] Therefore, there is an urgent need to provide a pixel arrangement structure, a display panel, and a display device that can significantly improve display resolution and obtain excellent display effects. Summary of the Invention

[0030] refer to Figures 1 to 7As an object of the present invention, a pixel arrangement structure is provided, which includes a plurality of pixel units 1 arranged in an array form. The pixel unit 1 can also be called a physical pixel unit 1 and is a regular unit. Each pixel unit 1 includes a first sub-pixel 2, a second sub-pixel 3 and a third sub-pixel 4 and is respectively L sub-pixel rows and M sub-pixel columns aligned horizontally and vertically. It should be noted that different sub-pixels can use LED chips that display different lights. The total number of sub-pixels is 3N, wherein L, M and N are all positive integers and greater than 2, so the total number of sub-pixels is actually equal to L×M and greater than or equal to 3×2=6, so that at least one of L or M is greater than or equal to 3, each sub-pixel row of each pixel unit 1 includes at least two different sub-pixels and at most only one sub-pixel column has two adjacent and identical sub-pixels. Each pair of adjacent aligned sub-pixel rows and two sub-pixel columns in a pixel unit 1 forms a pixel point 5. Therefore, for each independent pixel unit 1, its two adjacent sub-pixel columns on the left and right and its two adjacent sub-pixel rows on the top and bottom can share two sub-pixels, thereby achieving the effect of pixel multiplexing within each pixel unit 1. Furthermore, in the row extension direction X, each sub-pixel in each sub-pixel column in two adjacent pixel units 1 is located at the four vertices of a virtual rectangle, thereby forming a pixel point 5; in the column extension direction Y upward, each sub-pixel in each sub-pixel row in two adjacent pixel units 1 is located at the four vertices of a virtual rectangle, thereby forming a pixel point 5. Therefore, for each pair of adjacent pixel units 1, their two adjacent sub-pixel columns on the left and right and their two adjacent sub-pixel rows on the top and bottom can share two sub-pixels, thereby achieving pixel multiplexing. The pixel point 5 obtained by pixel multiplexing can also be called a virtual pixel point. Therefore, the pixel arrangement structure can obtain more pixel points 5 by realizing multiple locations sharing two sub-pixels arranged in the row or column direction in a single pixel unit 1 and between two adjacent pixel units 1, thereby achieving the purpose of significantly improving the display resolution and optimizing the display effect.

[0031] The pixel arrangement structure is described in more detail below in conjunction with multiple embodiments of the pixel arrangement structure.

[0032] Please refer to further Figure 1 、 2 , 3 and 4, in the first embodiment, the second embodiment, the third embodiment and the fourth embodiment of the pixel arrangement structure, L, M and N are set to 3, 2 and 2 respectively, that is, the sub-pixels in the pixel unit 1 are arranged in a 3×2 rectangular matrix shape, in the column extension direction Y, Figure 1 The pixel unit 1 and some pixel multiplexing of the first embodiment of the pixel arrangement structure are shown. In each pixel unit 1, one sub-pixel column includes two adjacent identical sub-pixels and another different sub-pixel, and the other sub-pixel column includes two alternate identical sub-pixels and another different sub-pixel. Figure 2As shown in FIG. 1 , as a pixel unit 1 of the second embodiment of the pixel arrangement structure, one sub-pixel column of each pixel unit 1 includes two adjacent identical sub-pixels and another different sub-pixel, and the sub-pixels in the other sub-pixel column are different. Figure 3 As shown, as the pixel unit 1 of the third embodiment of the pixel arrangement structure, one sub-pixel column of each pixel unit 1 includes two adjacent identical sub-pixels and another different sub-pixel, and another sub-pixel column includes two adjacent identical sub-pixels and another different sub-pixel, and the two pairs of two adjacent identical sub-pixels are different seed pixels. Figure 4 As shown in the figure, as a pixel unit 1 of the fourth embodiment of the pixel arrangement structure, the two sub-pixel columns of each pixel unit 1 include three different sub-pixels. Therefore, the four different embodiments of the pixel arrangement structure can all achieve rectangular multiplexing of two sub-pixels in the row or column direction, which not only improves display resolution and optimizes display effects, but also allows the corresponding pixel arrangement structure embodiment to be selected according to actual needs, thereby repeatedly refining the application scenarios of the pixel arrangement structure.

[0033] Specifically, relative to the extending direction X of the row and along the extending direction Y of the column, each pixel unit 1 is divided from left to right into a first sub-pixel column and a second sub-pixel column, as shown in FIG. Figure 1 As shown, in the first embodiment of the pixel arrangement structure, the first sub-pixel column of the pixel unit 1 is arranged as two third sub-pixels 4 and a first sub-pixel 2, and the second sub-pixel column is arranged as a second sub-pixel 3, a first sub-pixel 2, and a second sub-pixel 3. Figure 2 As shown, in the second embodiment of the pixel arrangement structure, the first sub-pixel column of the pixel unit 1 is arranged as two third sub-pixels 4 and a first sub-pixel 2, and the second sub-pixel column is arranged as a second sub-pixel 3, a first sub-pixel 2 and a third sub-pixel 4. Figure 3 As shown, in the third embodiment of the pixel arrangement structure, the first sub-pixel column of the pixel unit 1 is arranged as two third sub-pixels 4 and a first sub-pixel 2, and the second sub-pixel column is arranged as a first sub-pixel 2 and two second sub-pixels 3. Figure 4 As shown, in the fourth embodiment of the pixel arrangement structure, the first sub-pixel column of the pixel unit 1 is arranged as the second sub-pixel 3, the third sub-pixel 4, and the first sub-pixel 2, and the second sub-pixel column is arranged as the first sub-pixel 2, the second sub-pixel 3, and the third sub-pixel 4. In this way, LED chips that display different colors of light can be selected based on production cost, color vividness, etc. to produce pixel arrangement structures that meet different practical needs.

[0034] Please refer to further Figure 5In the fifth embodiment of the pixel arrangement structure, L, M, and N are set to 3, 4, and 4 respectively. Each sub-pixel row of each pixel unit 1 includes three different sub-pixels and each sub-pixel column includes three different sub-pixels. Compared with the existing pixel unit 1 in the prior art in which each sub-pixel row and each sub-pixel column only includes two different sub-pixels, so that each outer row and column of the pixel unit 1 will produce color lines or bright and dark lines, however, each outer row and column of the pixel unit 1 of the present pixel arrangement structure embodiment, i.e., the four edges of the rectangle, includes three different sub-pixels, and Figure 5 The row-oriented rectangle 6 and the column-oriented rectangle 7 respectively indicate two sub-pixel rows and two sub-pixel columns located on the outside, thereby reducing the occurrence of color lines or bright and dark lines, which is conducive to ensuring excellent display effects.

[0035] Specifically, relative to the column extension direction Y and along the row extension direction X, the first sub-pixel row is arranged as the second sub-pixel 3, the third sub-pixel 4, the second sub-pixel 3, and the first sub-pixel 2; the second sub-pixel row is arranged as the third sub-pixel 4, the first sub-pixel 2, the third sub-pixel 4, and the second sub-pixel 3; and the third sub-pixel row is arranged as the first sub-pixel 2, the second sub-pixel 3, the first sub-pixel 2, and the third sub-pixel 4. Through repeated experiments, the inventors have found that arranging the sub-pixels in this specific manner in pixel unit 1 can significantly reduce the occurrence of color lines or bright and dark lines.

[0036] Please refer to further Figure 6 and 7 In the sixth embodiment of the pixel arrangement structure, L, M, and N are set to 3, 3, and 3, respectively. The three sub-pixels in each sub-pixel row of each pixel unit 1 are different from each other, and the three sub-pixels in each sub-pixel column are different from each other. Based on the above description, similar to the fourth embodiment of the pixel arrangement structure, the pixel arrangement structure of this embodiment includes three different sub-pixels in each outer row and column, i.e., the four edges of the rectangle. This can reduce the occurrence of color lines or bright and dark lines, which is conducive to ensuring excellent display effects.

[0037] Specifically, relative to the column extension direction Y and along the row extension direction X, the first sub-pixel row of each pixel unit 1 is arranged as the second sub-pixel 3, the first sub-pixel 2, and the third sub-pixel 4; the second sub-pixel row is arranged as the third sub-pixel 4, the second sub-pixel 3, and the first sub-pixel 2; and the third sub-pixel row is arranged as the first sub-pixel 2, the third sub-pixel 4, and the second sub-pixel 3. Through repeated experiments, the inventors have found that arranging the sub-pixels in this specific manner for pixel unit 1 can significantly reduce the occurrence of color lines or bright-dark lines.

[0038] In summary, for the fifth and sixth embodiments of the above-mentioned pixel arrangement structures, since the sub-pixel rows and sub-pixel columns located on the four sides of the outermost rectangle of the rectangular pixel arrangement structure obtained by splicing multiple pixel units 1 with each other, as well as the sub-pixel rows and sub-pixel columns located inside and between two adjacent pixel units 1, all include three different sub-pixels, both of which achieve the purpose of reducing the occurrence of color lines or bright and dark lines, thereby both being conducive to ensuring excellent display effects.

[0039] Specifically, the first sub-pixel 2, the second sub-pixel 3 and the third sub-pixel 4 are used to display red light, green light and blue light respectively. In this way, each sub-pixel is relatively easy to obtain, which is conducive to the production of the pixel arrangement structure and reduces costs.

[0040] As another object of the present invention, a display panel is provided that has the effects of any of the above pixel arrangement structures, which will not be described in detail here. The display panel can be an OLED (Organic Light-Emitting Diode) display panel, a COB display panel, an LED (Light Emitting Diode) display panel, etc.

[0041] As another object of the present invention, a display device is provided that has the effects of any of the above display panels, which will not be described in detail here. For example, the display device can be a display screen, a mobile phone, a tablet, a PDA, a smart watch or other digital device.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
