Description
Technical Field
The invention relates to the technical field of optoelectronics and information display, in particular to an LED sub-pixel arrangement structure and a module.
Background
With the development of the novel ultra-high density LED flat panel display technology, the LED becomes the first choice technology of the display screen for the ultra-large high-image-quality television in the future, has the advantages of wide color gamut, high luminous efficiency, high response speed, wide working temperature range and the like, is widely applied to the fields of high-end display, flat panel display backlight source and illumination, and has important market prospect especially in the fields of cinema, medical teaching and the like.
An important index affecting the image quality of a high-density LED display screen is screen definition, which is mainly embodied in aspects of image spatial resolution, image display hierarchical resolution, pixel optical crosstalk degree, pixel edge fusion degree and the like, wherein the image spatial resolution is displayed by an LED according to the arrangement mode of LED pixels and pixel density. The usual pixel density refers to the distance between the full pixels, but there is actually a concept of a non-center-distributed pixel arrangement and its pixel-related distance, i.e. a sub-pixel arrangement structure.
The Guan Ya pixel distribution is that each primary color of the pixels is not completely concentrated at one position, but is distributed on a display panel according to a certain proportion, the initial patent purpose of the aspect is to improve the information display capability of pixel multiplexing, and the invention patent CN1892745A applied by scientific researchers of the national academy of sciences of China is representative of a method for improving the image resolution of a display screen by pixel multiplexing, wherein a schematic diagram of the arrangement of LED primary color dies on the panel is given, as shown in the attached figure 1; to illustrate the die distribution of the surface, the RGB three primary colors of the original specification are replaced by 101 primary colors, 102 primary colors and 103 primary colors. From the view of the LED die arrangement in the figure, the following features are mainly provided: 1) One primary is equal to the sum of the other two primary, in the figure the number of 101 primary dies is 2 times that of 102 primary dies, and also 2 times that of 103 primary dies; 2) The periphery of the tube core with less primary colors is provided with more primary colors, the periphery of the 102 primary tube cores in the figure is provided with 101 primary tube cores, and the periphery of the 103 primary tube cores is provided with 101 primary tube cores; 3) Two cases are arranged around the tube core with a large number of primary colors, wherein one case is a 102 primary tube core from top to bottom and 103 primary tube cores from left to right; the other is a primary color tube core with a left primary color tube core and a right primary color tube core with a top primary color tube core with a bottom primary color tube core with a top primary; 4) If 4 dies are defined as one basic pixel, it can be seen that the dies with a larger number of primary colors extend from top left to bottom right starting from either the odd columns of the odd rows or the even columns of the even rows of the panel; 5) If starting from the odd-numbered rows and columns of the panel or the even-numbered rows and columns, the die with a greater number of primary colors extends from top right to bottom left.
The patent adopts a virtual pixel technology in the control aspect except for the arrangement aspect, improves the fusion degree of pixel edges and reduces the pixel spacing of virtual display.
In addition to the above-described sub-pixel distribution in which the number of primary colors is not exactly equal, the sub-pixel distribution in which the number of primary colors is exactly equal is also used in a large number of applications; for example, fig. 2 shows a tube core of a primary color column of LEDs arranged alternately, that is, each primary color is arranged in a column, and the primary colors are sequentially and alternately exchanged on a panel for arrangement; the method is characterized in that: 1) The number of the primary colors is completely equal, and the number of the R primary color dies in the figure is equal to the G primary color and the B primary color; 2) The upper and lower of each primary color are the same primary color tube core, the left and right are other tube cores of different primary colors, and the left and right tube cores cannot be the same primary color; 3) The lateral R, G, and B primary colors can be regarded as elements of one pixel, so that the pixel element extends left and right while extending vertically in the up-down direction.
Based on the arrangement mode, the invention patent CN103325320A discloses an LED display screen with the same-color chips arranged in an oblique line mode and a pixel multiplexing method, and discloses a sub-pixel right oblique arrangement distribution prototype with the same primary color quantity; FIG. 3 is a distribution diagram of the arrangement, namely, each primary color is arranged into inclined nematic, and the primary colors are sequentially and alternately exchanged on a panel for arrangement; the method is characterized in that: 1) The number of the primary colors is completely equal, and the number of the R primary color dies in the figure is equal to the G primary color and the B primary color; 2) The upper and lower primary colors are different primary color dies, the upper and lower dies cannot be the same primary color, the left and right dies are other dies of different primary colors, and the left and right dies cannot be the same primary color; 3) The horizontal R, G, and B primary colors can be regarded as elements of one pixel, so that the pixel elements extend left and right in the same row direction, and each vertically downward by one row in the up-down direction, the positions of the dies are moved rightward to extend.
In the above-mentioned subpixel arrangement scheme, a comprehensive scheme appears, and the scheme integrates the characteristics of alternating arrangement of the longitudinal tube cores and oblique arrangement and distribution of the subpixels; the LED tube core sub-pixel staggered arrangement mode is named as an LED tube core sub-pixel staggered arrangement mode, and is shown in figure 4; the method refers to the characteristic of oblique arrangement distribution on the basis of the alternating arrangement of LED primary color column tube cores, and the extension arrangement is carried out in different directions by odd-even rows; as can be seen from the figure, it is characterized in that: 1) The number of the primary colors is completely equal, and the number of the R primary color dies in the figure is equal to the G primary color and the B primary color; 2) The upper and lower of each primary color is the same primary color tube core different from the primary color, the corresponding conditions of the upper and lower tube cores are fixed, the left and right tube cores are other tube cores of different primary colors, and the left and right tube cores cannot be the same primary color; 3) The R, G and B color primaries in the horizontal direction can be regarded as elements of a pixel, so that the pixel elements extend leftwards and rightwards in the same row direction, and if the positions of odd rows are not moved under the premise of stipulating odd-even rows, the sub-pixels of even rows are all extended leftwards and rightwards by the positions of a tube core, and the whole distribution forms a pixel staggered distribution.
The staggered arrangement mode of the LED tube core sub-pixels is that the LED primary color column tube cores are arranged alternately, if a complete pixel is made according to the transverse R primary color, G primary color and B primary color, the complete pixel is marked as P1; as shown in fig. 5; the space between the upper and lower structures of the complete pixel P1 is staggered into a sub-pixel, and the relative relation is clearly shown in fig. 6; the changing relationship between the complete pixels P1 can be seen.
The staggered arrangement mode of the LED tube core sub-pixels is that the staggered position is changed into complete sub-pixels, and the new change is that incomplete sub-pixels are changed in the column direction on the basis; on the basis of the staggered arrangement mode of the sub-pixels of the LED tube cores shown in the figure 5, the sub-pixels in even columns are arranged in an extending mode in the vertical direction, all the sub-pixels in even columns are moved down by half sub-pixel positions, and the arrangement is shown in the figure 7; two kinds of deformation of the original complete pixel P1 can be seen, one is PP1, namely the middle sub-pixel of the complete pixel floats upwards by half sub-pixel positions; the other is PP2, the middle sub-pixel of the complete pixel is lowered by half a sub-pixel position; this results in the arrangement shown in fig. 7; the method is characterized in that: 1) The number of the primary colors is completely equal, and the number of the R primary color dies in the figure is equal to the G primary color and the B primary color; 2) The upper and lower of each primary color are the same primary color tube core different from the primary color, and the corresponding conditions of the upper and lower tube cores are fixed; 3) The left and right of each primary color have no sub-pixel, and the left upper right upper left lower left and right lower right are adjacent to each other.
The invention patent CN115084186A pixel arrangement structure and the virtual pixel structure based on the pixel arrangement structure are precisely based on the staggered arrangement condition of the sub-pixels for grouping control, and can be seen that the patent document directly adopts the arrangement pattern for discussion; to describe the patent more in real time, the original patent graph is further refined in fig. 8; as shown in fig. 8, the invention CN115084186a provides the following technical scheme: the physical pixel units of the pixel arrangement structure comprise four sub-pixels, namely a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel; in the A direction, the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel are sequentially arranged; in the B direction, the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel are arranged in a staggered manner in sequence; as shown in fig. 8, although the physical pixel unit constructed in the invention CN115084186a will not follow the original three primary colors (sub-pixels) unit, but will be recombined, on the premise that the overall arrangement is the same as that described in fig. 7; namely, under the staggered condition, four sub-pixels are arranged in a classified manner, so that physical pixel units such as PB11, PB12, PB13 … … PB15, PB16 and the like are divided on the first physical pixel unit row in the B direction, and homotypic expansion of the physical pixel unit row is carried out in the A direction, namely PB21, PB22, PB23 … … PB25, PB26, … … and PB31, PB32, PB33 … … PB35, PB36 and … … are respectively calculated; it can be seen that in the direction of the physical pixel element row, taking the top row as an example, the four sub (sub) pixels of physical pixel element PB11, the R primary and the B primary are located at the top left and bottom right, with two identical G primaries arranged diagonally therebetween; four sub-pixels of the physical pixel unit PB12, wherein the B primary color and the G primary color are positioned at the upper left and the lower right, and two identical R primary colors are obliquely arranged between the two; four sub-pixels of the physical pixel unit PB13, wherein the G primary color and the R primary color are positioned at the upper left and the lower right, and two identical B primary colors are obliquely arranged between the two sub-pixels; then the physical pixel unit PB14, the situation is completely consistent with PB 11; also, the physical pixel unit PB15 is equivalent to PB12; the physical pixel unit PB16 is equivalent to PB13; such a cyclic structure is an inherent feature of the staggered arrangement of the LED die sub-pixels and is not a unique variation of this patent; in the direction a, the same type is adopted, and it can be clearly seen that the physical pixel units PB21 and PB31 are identical to the PB 11; the physical pixel units PB22 and PB32 are identical to PB12; the physical pixel units PB23 and PB33 are identical to PB13; … … physical pixel elements PB26, PB36 are identical to PB 16.
Although this patent has been re-combined for three primary (sub-pixel) cells, the drawbacks are also apparent: 1) In the column direction (direction a described in patent CN115084186 a), the physical pixel units are arranged in a uniform manner substantially in a line, and such structural uniformity cannot be effectively dispersed, so that a distribution difference from the row direction (direction B described in patent CN115084186 a) is caused, and vertical lines are likely to occur; 2) In the row direction (direction B described in patent CN115084186 a), the physical pixel units such as PB11, PB12, and PB13 are configured in three groups and one cycle, and the boundary difference is easily formed, and the viewing characteristics of the structure in the column direction (direction a described in patent 202210927908.1) are enlarged.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments.
Embodiment one: the present embodiment is described with reference to fig. 9 and 10. The LED subpixel arrangement structure according to the present embodiment includes physical pixel units arranged in a matrix form, where each physical pixel unit includes a first subpixel module, a second subpixel module, and a third subpixel module;
in the row direction, the first sub-pixel module, the second sub-pixel module and the third sub-pixel module are sequentially arranged;
in the column direction, the first sub-pixel module, the second sub-pixel module and the third sub-pixel module are arranged at intervals.
Fig. 9 is an overall structure of an LED sub-pixel arrangement structure, and fig. 10 is a schematic block diagram, as shown in fig. 10, in which each physical pixel unit includes a first sub-pixel module PC11, a second sub-pixel module PC12 and a third sub-pixel module PC13. In the row direction, i.e., the B direction, the PC11, the PC12, and the PC13 are arranged in order; in the column direction, i.e., the a direction, the PCs 11, 12, 13 are arranged at intervals.
The present embodiment can realize higher resolution display by combining three different sub-pixel modules into each physical pixel unit. Each physical pixel unit can provide more detail and color information, so that the image is clearer and more real. Different sub-pixel modules contain different red (R), green (G) and blue (B) channels, and rich colors can be more accurately restored through different permutation and combination. This physical arrangement may provide a wider color gamut and more accurate color representation. And since each physical pixel unit contains a plurality of sub-pixel modules, higher brightness and contrast can be achieved by brightness control of the sub-pixel modules. This means that the LED display screen can project brighter, clearer and more vivid images.
In this arrangement, since the three sub-pixel modules in each physical pixel unit are densely arranged, and the color information is more abundant, the viewing angle is less affected. This allows viewers to enjoy high quality images over a wider range, whether facing the screen or viewed from the side.
In summary, the above arrangement can provide higher resolution, more accurate color reproduction, higher brightness and contrast while maintaining image quality over a wide viewing angle by integrating different sub-pixel modules into the physical pixel unit. These characteristics enable the LED display screen to have better image quality and visual effect.
Embodiment two: the present embodiment is described with reference to fig. 10. The present embodiment is further defined by the LED subpixel arrangement structure of the first embodiment, where the first subpixel module includes two first color lights, one second color light, and one third color light, the two first color lights are in an upper left corner and a lower right corner of the matrix, the second color light and the third color light are both between the two first color lights, and the second color light and the third color light are both offset from each other in a row direction and a column direction;
the second color light is aligned with the first color light at the upper left corner of the matrix in the column direction, and the second color light is offset with the first color light at the lower right corner of the matrix in the row direction;
the third color light is aligned with the first color light in the lower right corner of the matrix in the column direction, and the third color light is offset with the first color light in the upper left corner of the matrix in the row direction.
In the LED subpixel arrangement structure according to the present embodiment, by using two first color lights, one second color light, and one third color light, a wide range of colors can be more accurately restored. This arrangement takes full advantage of the interaction between the different color channels, making the color appearance more accurate and fine. The two first color lights are respectively positioned at the left upper corner and the right lower corner of the matrix, and the second color light and the third color light are positioned between the two first color lights. Such an arrangement enables details to be better captured and presented. By placing two pixels of the same color in diagonal positions, the discontinuity of color transitions can be reduced, making the transition of the image smoother. The second color light and the third color light are arranged offset from each other in the row direction and the column direction. This staggered arrangement reduces cross-contamination between colors. Through staggered arrangement in different directions, the mutual interference of color signals between adjacent pixels can be reduced, and the independence and color accuracy of each sub-pixel module are improved.
Embodiment III: the present embodiment is further defined by the LED subpixel arrangement structure according to the second embodiment, wherein a distance between the second color light and the first color light in the upper left corner of the matrix in the column direction is a unit pixel pitch, a distance between the second color light and the first color light in the lower right corner of the matrix in the column direction is a half unit pixel pitch, and a distance between the second color light and the first color light in the lower right corner of the matrix in the row direction is a unit pixel pitch; the distance between the third color light and the first color light at the right lower corner of the matrix in the column direction is a unit pixel pitch, the distance between the third color light and the first color light at the left upper corner of the matrix in the column direction is a half unit pixel pitch, and the distance between the third color light and the first color light at the left upper corner of the matrix in the row direction is a unit pixel pitch.
Embodiment four: the present embodiment is described with reference to fig. 10.

the first color light is aligned with the second color light at the right lower corner of the matrix in the column direction, and the first color light is offset with the second color light at the left upper corner of the matrix in the row direction.
According to the LED sub-pixel arrangement structure described above, the second sub-pixel module includes one first color light, two second color lights, and one third color light. The advantages of this arrangement are as follows:
by placing the first and third color light between the two second color light, an even distribution of the three basic colors red, green and blue over the entire display screen is ensured. The arrangement mode can effectively reduce color deviation, so that the displayed image color is more real and accurate. The two second colored lights are respectively positioned at the left upper corner and the right lower corner of the matrix, and the first colored light and the third colored light are positioned between the two second colored lights. This arrangement helps to improve the detail rendering of the image. By placing pixels of the same color in diagonal positions, abrupt changes in color transitions can be reduced, making the detail transitions of the image smoother and more natural. The first color light and the third color light are arranged in a staggered manner in the row and column directions, and meanwhile, the third color light is aligned with the second color light at the upper left corner of the matrix, and the first color light is aligned with the second color light at the lower right corner of the matrix. The staggered arrangement mode can reduce the cross interference of color signals between adjacent pixels and improve the independence and color resolution of each sub-pixel module.
