Description

Technical Field

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

[0002] With the continuous promotion of the ultra-high-definition display industry by the country, 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 has opened up a new application market for LED sub-pixel technology and promoted the development of the LED display industry.

[0003] LED sub-pixel technology has irreplaceable positive significance in breaking through the bottleneck of high-density Micro LED development. Sub-pixel technology splits 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 multiplexed manner. Compared with the conventional logical pixel arrangement, the sub-pixel multiplexing technology can realize the logical pixel pitch smaller than the physical pixel pitch. Under limited cost increase, the logical pixel quantity in resolution can be increased to a higher resolution, thereby improving the resolution of LED display screens. Sub-pixel arrangement generally includes specifications such as rectangular horizontal arrangement of three primary colors and oblique triangle arrangement. Although the clarity of logical pixels still cannot completely replace the visual clarity effect of physical pixels, it still multiplies the perceptible visual clarity of the picture, achieving higher quality picture quality for LED large-size displays under "cost controllable, reliable and mature processes". This sub-pixel multiplexing technology will not only improve the resolution, but also bring color errors, so the sub-pixel display control algorithm generally strikes a balance between improving resolution and reducing 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. Equal primary color arrangement means that the total number of each primary color on the panel is the same. Non-equal primary color arrangement means that the number of each primary color can be different. There are balanced symmetry and unbalanced symmetry in the arrangement method. At present, the general arrangement design generally abides by the principle of equal primary color balanced symmetry, and strives to obtain a balanced and symmetrical sub-pixel primary color display effect. However, under certain specific requirements, the above method may not meet the actual needs.

[0005] In summary, the existing layout design generally complies with the principle of equal primary color balanced symmetry, but under certain specific requirements, the layout design may not meet the actual needs. Summary of the invention

[0006] The present invention solves the problem that the existing arrangement design generally complies with the principle of equal primary color balanced symmetry, but under certain specific requirements, the arrangement design may not meet the actual needs.

[0007] A pixel arrangement structure described in the present invention is arranged in sequence in the form of pixel units in the horizontal direction, each pixel unit includes multiple rows and columns of sub-pixels, and the sub-pixels in the multiple rows and columns are arranged in an interlaced manner. In the column direction, the sub-pixels in each pixel unit are arranged in sequence according to i, i+1, ..., i+n, and in the row direction, the sub-pixels in each pixel unit are arranged in sequence according to j, j+1, ..., j+n, wherein the i+1th column sub-pixels of each pixel unit are arranged with the same primary color, and the i+2th column and j+1th row sub-pixels of each pixel unit and the i-th column and j-row sub-pixels of the adjacent pixel unit, and the i-th column and j+2nd row sub-pixels are arranged with the same primary color, and i, j, and n are all positive integers.

[0008] Furthermore, in an embodiment of the present invention, the sub-pixels in the (i+1)th column and the sub-pixels in the (i)th column of each pixel unit are of different primary colors, and the sub-pixels in the (i)th column include at least two different primary colors.

[0009] Furthermore, in an embodiment of the present invention, the sub-pixels in the (i+1)th column of each pixel unit are all red primary color, green primary color or blue primary color.

[0010] Further, in one embodiment of the present invention, the i-th column of sub-pixels of each pixel unit includes at least two different primary colors, specifically:

[0011] The i-th column j-row subpixel and the i-th column j+2-row subpixel have the same primary color, and the i-th column j-row subpixel, the i-th column j+2-row subpixel and the i-th column j+1-row subpixel have two different primary colors.

[0012] Furthermore, in one embodiment of the present invention, the sub-pixel in the i+2th column and j+1th row and the sub-pixel in the i+2th column and jth row, and the sub-pixel in the i+2th column and j+2th row of each pixel unit are different primary colors, and the sub-pixel in the i+2th column includes at least two different primary colors.

[0013] Furthermore, in one embodiment of the present invention, the sub-pixel in the i+2th column and j+1th row of each pixel unit and the sub-pixel in the i-th column and j-th row of the adjacent pixel unit, as well as the sub-pixel in the i-th row and j+2nd row are all red primary colors, green primary colors or blue primary colors.

[0014] Further, in one embodiment of the present invention, the sub-pixels in the i+2th column include at least two different primary colors, specifically:

[0015] The i+2nd column j row subpixel and the i+2nd column j+2 row subpixel have the same primary color, and the i+2nd column j row subpixel, the i+2nd column j+2 row subpixel and the i+2nd column j+1 row subpixel have two different primary colors.

[0016] The present invention provides a virtual multiplexing method for a pixel arrangement structure, which is implemented by using a pixel arrangement structure described in any one of the above methods, specifically:

[0017] In each pixel unit, there is a situation where the sub-pixel in the i-th column and j-th row, the sub-pixel in the i+1-th column and j-th row and the sub-pixel in the i-th column and j+2-th row, the sub-pixel in the i+1-th column and j+2-th row share a sub-pixel;

[0018] There is a case where the sub-pixel in the i+2th column and jth row shares two sub-pixels with the sub-pixel in the i+2th column and j+2nd row.

[0021] A pixel arrangement structure described in the present invention solves the problem that the existing arrangement design generally complies with the principle of equal primary color balanced symmetry, but under certain specific requirements, the arrangement design may not meet the actual needs. In order to solve the above technical problems, the present invention adopts an arrangement structure of sub-pixel equal primary color non-uniform symmetry, that is, an arrangement structure with the same primary color sub-pixels symmetrical around the logical pixel unit and asymmetric between different primary color sub-pixels: 1) The sub-pixel primary colors that need to be concentrated and highlighted are placed in the middle of the logical unit; 2) Non-essential sub-pixel primary colors are placed at the edge of the logical pixel unit; 3) Non-essential sub-pixel primary colors at the edge of the logical pixel unit intersect and become prominent sub-pixel primary colors during pixel multiplexing. The original prominent sub-pixel primary colors now become the edge position primary colors, which effectively reduces the information imbalance caused by sub-pixel multiplexing, thereby solving the problem that the general arrangement design cannot meet the actual conditions under certain specific requirements;

[0022] The pixel arrangement structure described in the present invention is suitable for light-emitting chips of various types and models of LEDs. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will clearly and completely describe various embodiments of the present invention in conjunction with the accompanying drawings. The embodiments described with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] Embodiment 1. A pixel arrangement structure described in this embodiment, wherein the pixel arrangement structure is arranged in sequence in the form of pixel units in the horizontal direction, each pixel unit includes multiple rows and columns of sub-pixels, and the sub-pixels in multiple rows and columns are arranged alternately, and in the column direction, the sub-pixels in each pixel unit are arranged in sequence according to i, i+1, ..., i+n, and in the row direction, the sub-pixels in each pixel unit are arranged in sequence according to j, j+1, ..., j+n, wherein the sub-pixels in the i+1th column of each pixel unit are arranged with the same primary color, and the sub-pixels in the i+2th column and j+1th row of each pixel unit and the sub-pixels in the i-th column and j-row of the adjacent pixel unit are arranged with the same primary color, and i, j, and n are all positive integers.

[0033] In the prior art, the existing layout design generally complies with the principle of equal primary color balanced symmetry. However, under certain specific requirements, the layout design may not necessarily meet the actual needs.

[0034] In order to solve the technical problems existing in the prior art, in this embodiment, Figure 1 As shown, the pixel arrangement structure has a plurality of pixel units arranged in sequence in the horizontal direction, and one pixel unit is Figure 1 The dotted box is composed of multiple rows and columns of sub-pixels, and each pixel unit repeats the arrangement of the multiple rows and 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 recorded as i, i+1, i+2, and the sub-pixels in the row direction are sequentially recorded as j, j+1, j+2, and i and j are both positive integers.

[0048] In this embodiment, the sub-pixel in the i+2th column and j+1th row of each pixel unit and the sub-pixel in the i-th column and j-th row of the adjacent pixel unit, as well as the sub-pixel in the i-th row and j+2nd row are all red primary colors, green primary colors or blue primary colors.

[0049] In this embodiment, the sub-pixels in the i+2th column include at least two different primary colors, specifically:

At this time, the i-th column sub-pixels in the pixel unit and its adjacent pixel units are all red primary colors;

[0052] Or, if Figure 2As shown, when the i+1th column sub-pixels are all green primary colors, the i+2th column j+1th row sub-pixels are blue primary colors, the i+2th column jth row sub-pixels and the i+2th column j+2th row sub-pixels are red primary colors. At this time, the i+1th column sub-pixels in the pixel unit and its adjacent pixel units are all blue primary colors.

[0059] Embodiment 4: A virtual multiplexing method of a pixel arrangement structure described in this embodiment, wherein the virtual multiplexing method is implemented by using a pixel arrangement structure described in any one of Embodiments 1 to 3, specifically:

[0060] In each pixel unit, there is a situation where the sub-pixel in the i-th column and j-th row, the sub-pixel in the i+1-th column and j-th row and the sub-pixel in the i-th column and j+2-th row and the sub-pixel in the i+1-th column and j+2-th row share a sub-pixel;

[0061] There is a case where the sub-pixel in the i+2th column and jth row shares two sub-pixels with the sub-pixel in the i+2th column and j+2nd row.

[0062] In this embodiment, based on a pixel arrangement structure described in embodiments 1 to 3, a corresponding virtual multiplexing method is provided. In each pixel unit, the virtual multiplexing method realizes the situation where an inverted triangle and an equilateral triangle share one vertex, and an equilateral triangle and an inverted triangle share two vertices, specifically:

[0063] like Figure 7 As shown, in each pixel unit, the sub-pixel located at the i-th column and j-th row, the sub-pixel located at the i+1-th column and j-th row, and the sub-pixel located at the i-th column and j+2-th row, and the sub-pixel located at the i+1-th column and j+2-th row share the sub-pixel located at the i-th column and j+1-th row;

[0064] Meanwhile, in the pixel unit, the sub-pixel at the i+2th column and jth row and the sub-pixel at the i+2th column and j+2th row share the sub-pixel at the i+1th column and j+1th row and the sub-pixel at the i+2th column and j+1th row.

[0065] When the i+1th column of sub-pixels are all green primary colors, blue primary colors, or red primary colors, the above virtual multiplexing method is met, that is, Figures 2 to 3 For each pixel unit, there is a situation where the sub-pixel in the i-th column and j-th row, the sub-pixel in the i+1-th column and j-th row and the sub-pixel in the i-th column and j+2-th row, and the sub-pixel in the i+1-th column and j+2-th row share a sub-pixel;

[0066] There is a case where the sub-pixel in the i+2th column and jth row shares two sub-pixels with the sub-pixel in the i+2th column and j+2nd row.

[0067] Therefore, in the pixel arrangement structure described in any one of embodiments 1 to 3 of the present invention, since one sub-pixel can be reused twice, double virtual pixel multiplexing is achieved. The double virtual pixel multiplexing technology can effectively improve the display effect of the image on a display device with a lower resolution, making the image clearer, more delicate and realistic.

[0068] Embodiment 5: A display described in this embodiment is implemented by using a pixel arrangement structure described in any one of embodiments 1 to 3.
