Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a pixel arrangement structure, a virtual multiplexing method and a display. BACKGROUND

[0002] With the continuous promotion of the country to the ultra-high-definition display industry, the display resolution has developed from 2K high-definition display to 4K and 8K ultra-high-definition display. The application of 4K and 8K ultra-high-definition display opens up a new application market for LED sub-pixel technology and promotes the development of the LED display industry.

[0003] LED sub-pixel technology has irreplaceable positive significance for breaking through the development bottleneck of high-density Micro LED. Sub-pixel technology divides the original logical pixel into several independent sub-pixel units, and the units realize the corresponding primary colors of several adjacent sub-pixels in a multiplexing manner. Compared with the conventional logical pixel arrangement, the sub-pixel multiplexing technology can realize a logical pixel pitch smaller than a physical pixel pitch. With limited cost increase, the logical pixel amount in resolution can be improved to a higher resolution, and the resolution of the LED display screen is improved. Sub-pixel arrangement generally includes three primary color rectangular column arrangement, diagonal triangle arrangement and other specifications. Although the clarity of the logical pixel cannot completely replace the visual clarity effect of the physical pixel, it still doubles the visual clarity of the perceived picture, and realizes higher quality of the picture under the condition of "controllable cost, reliable and mature technology" for the LED large-size display. This sub-pixel multiplexing technology not only improves the resolution, but also brings color errors, so the sub-pixel display control algorithm generally balances the improvement of resolution and the reduction of color errors to achieve the best display effect.

[0004] At present, the sub-pixel arrangement is basically divided into equal primary color arrangement and non-equal primary color arrangement. The equal primary color arrangement is that the total number of each primary color of the panel is the same. The non-equal primary color arrangement is that the number of each primary color can be different, and there are balanced symmetric type and unbalanced symmetric type in the arrangement method. The general arrangement design at present generally follows the principle of equal primary color balanced symmetry, and strives to obtain balanced and symmetric sub-pixel primary color display effect, but the above method does not necessarily meet the actual demand under certain specific requirements.

[0033] In the prior art, the existing arrangement design generally follows the principle of equal base color balance symmetry, but under certain specific requirements, the arrangement design does not necessarily meet the actual demand.

[0034] To solve the technical problems existing in the prior art, in the present embodiment, as shown in Figure 1 the pixel arrangement structure is arranged in multiple pixel units in the horizontal direction, one pixel unit is Figure 1 composed of multiple rows and multiple columns of sub-pixels in the dashed box, and each pixel unit repeats the arrangement of the multiple rows and multiple columns of sub-pixels. In order to describe the arrangement of the sub-pixels in each pixel unit, the sub-pixels in the column direction are sequentially denoted as i, i+1, i+2, and the sub-pixels in the row direction are sequentially denoted as j, j+1, j+2, i, j are positive integers.

[0035] In each pixel unit, the sub-pixels in the i+1th column and jth row, the i+1th column and j+1th row, and the i+1th column and j+1th row are arranged in the same base color, that is, all the sub-pixels in the i+1th column are arranged in the same base color, and in each pixel unit, the sub-pixels in the i+2th column and j+1th row, the sub-pixels in the ith column and jth row of the adjacent pixel unit, and the sub-pixels in the ith column and j+2th row are arranged in the same base color.

[0036] It can be seen that by using the sub-pixel equal-base-color non-uniform symmetrical arrangement structure, that is, the arrangement structure in which the sub-pixels in the same base color are symmetrical and the sub-pixels in different base colors are asymmetrical around the center (the logical pixel unit (such as Figure 1 The arrangement structure has the following advantages: 1) the sub-pixel base color that needs to be highlighted is placed in the middle position of the logical pixel unit; 2) the unnecessary sub-pixel base color is placed in the edge position of the logical pixel unit; 3) the unnecessary sub-pixel base color in the edge position of the logical pixel unit becomes the highlighted sub-pixel base color after pixel multiplexing, and the original highlighted sub-pixel base color becomes the base color in the edge position, thereby effectively reducing the information imbalance caused by sub-pixel multiplexing, and thereby meeting the problem that the arrangement design does not necessarily meet the actual requirements under certain specific requirements.

[0037] Embodiment two, the embodiment is a further limitation of the pixel arrangement structure of the first embodiment, wherein the sub-pixels in the i+1th column and the sub-pixels in the i th column of each pixel unit are in different base colors, and the sub-pixels in the i th column include at least two different base colors.

[0050] The sub-pixels in column (i+2) and row (j) have the same primary color, and the sub-pixels in column (i+2) and row (j+2) have two different primary colors.

[0051] In this embodiment, such as Figure 1 As shown, when all sub-pixels in the (i+1)th column are green, the sub-pixels in the (i+2)th column and (j+1)th row are red, and the sub-pixels in the (i+2)th column and (j)th row are blue. At this time, the sub-pixels in the i-th column of this pixel unit and its adjacent pixel units are all red.

[0052] Or, such as Figure 2As shown in FIG. 6, when the sub-pixels in the i+1th column are all green primary colors, the sub-pixel in the j+1th row of the i+2th column is a blue primary color, and the sub-pixels in the jth row and the j+2th row of the i+2th column are red primary colors.

[0053] As shown in FIG. 7, when the sub-pixels in the i+1th column are all red primary colors, the sub-pixel in the j+1th row of the i+2th column is a green primary color, and the sub-pixels in the jth row and the j+2th row of the i+2th column are blue primary colors. At this time, the sub-pixels in the i+2th column of the pixel unit and the adjacent pixel units are all green primary colors. Figure 3 As shown in FIG. 8, when the sub-pixels in the i+1th column are all red primary colors, the sub-pixel in the j+1th row of the i+2th column is a green primary color, and the sub-pixels in the jth row and the j+2th row of the i+2th column are blue primary colors. At this time, the sub-pixels in the i+2th column of the pixel unit and the adjacent pixel units are all green primary colors.

At this time, the sub-pixels in the i+2th column of the pixel unit and the adjacent pixel units are all green primary colors. Figure 5 As shown in FIG. 11, when the sub-pixels in the i+1th column are all blue primary colors, the sub-pixel in the j+1th row of the i+2th column is a green primary color, and the sub-pixels in the jth row and the j+2th row of the i+2th column are red primary colors. At this time, the sub-pixels in the i+2th column of the pixel unit and the adjacent pixel units are all green primary colors.
