The following further describes the content of the application by describing the embodiments with reference to the attached drawings.
The present embodiment provides a display method of pixel multiplexing, as shown in fig. 1, the method includes:
and S10, dividing the picture to be displayed into a candidate picture and a plurality of reference pictures based on the solid-state resolution of the display screen.
Specifically, the display screen is used for displaying a picture to be displayed, and the solid-state resolution of the display screen is smaller than the resolution of the picture to be displayed, for example, the solid-state resolution of the display screen is 2k resolution, the resolution of the picture to be displayed is 4k resolution, and for example, the solid-state resolution of the display screen is 256 × 256, the resolution of the picture to be displayed is 512 × 512, and the like. In addition, the display screen is a Micro-LED display screen, and it can be understood that the display screen can comprise a plurality of Micro-LED chips and a Micro-LED driving substrate, each of the plurality of Micro-LED chips is attached to the Micro-LED driving substrate and arranged in an array, wherein the plurality of Micro-LED chips comprise a plurality of Micro-LED chip sets, each Micro-LED chip set comprises a red Micro-LED chip, a green Micro-LED chip and a blue Micro-LED chip, and each Micro-LED chip set is used as a physical pixel of the display screen.
The candidate picture and the plurality of reference pictures are partial pictures of the picture to be displayed, and the candidate picture and each reference picture are not overlapped with each other, so that it can be understood that each picture pixel point in the candidate picture is not included in each reference picture; on the contrary, for any reference picture a, each picture pixel in the reference picture a is not included in the candidate picture and each reference picture B outside the reference picture a. The resolution of the candidate picture is the same as the solid-state resolution of the display screen, and the resolution of each of the plurality of reference pictures may be the same as the solid-state resolution of the display screen, or the resolution of one of the plurality of reference pictures is the same as the solid-state resolution of the display screen. That is to say, when the to-be-displayed picture is divided based on the solid-state resolution of the display screen, the sub-display pictures with the resolution are selected from the to-be-displayed picture by taking the solid-state resolution of the display screen as a unit, if the resolution of the to-be-displayed picture is a multiple of the solid-state resolution of the display screen, the resolution of each selected sub-display picture is equal to the solid-state resolution of the display screen, and if the resolution of the to-be-displayed picture is not the multiple of the solid-state resolution of the display screen, the resolution of one display picture in the selected display picture is smaller than the solid-state resolution of the display screen. And after each sub display picture is selected, selecting one sub display picture from the sub display pictures with the resolution equal to that of the display screen as a candidate picture, and taking each sub display picture except the candidate picture as a reference picture.
In one implementation of this embodiment, the resolution of the picture to be displayed is 4 times the solid-state resolution of the display screen, and the candidate picture and each reference picture are both the same as the solid-state resolution of the display screen. It can be understood that, based on the solid-state resolution of the display screen, the picture to be displayed may be divided into 4 display pictures, one of the 4 display pictures is used as a candidate picture, and the remaining three display pictures are used as reference pictures. For example, the solid-state resolution of the display screen is 2k resolution, and the resolution of the picture to be displayed is 4k resolution, so that the resolutions of the candidate picture and the 3 reference pictures are both 2k resolution; for another example, the solid-state resolution of the display screen is 4k resolution, and the resolution of the picture to be displayed is 8k resolution, so that the resolutions of the candidate picture and the 3 reference pictures are both 4k resolution, and the like.
In one implementation of this implementation, before dividing a picture to be displayed into a candidate picture and several reference pictures based on a solid-state resolution of a display screen, the method includes:
the array positions of a plurality of virtual pixel arrays corresponding to the display screen are preset.
Specifically, each of the number of virtual pixel arrays is determined based on solid state physical pixels of the display screen, and a resolution of each of the number of virtual pixel arrays is equal to a solid state resolution of the display screen. The array position of the virtual pixel array comprises position information of each virtual pixel in the virtual pixel array in the display screen, the position information of each virtual pixel in the virtual pixel array in the display screen is different from each other, and the position information of each virtual pixel in each virtual pixel array and the position information of the solid-state physical vector in the display screen are different from each other.
In one implementation manner of this embodiment, the plurality of virtual pixel arrays include a first virtual pixel array, a second virtual pixel array, and a third virtual pixel array. Each first virtual pixel in the first virtual pixel array is determined based on pixel information of two adjacent physical pixels located in a row direction, and pixel information of the first virtual pixel is determined based on pixel information of two physical pixels used for determining the virtual pixel, and for any two physical pixels adjacent in the row direction in the display screen, a first virtual pixel is arranged between the two physical pixels. For example, as shown in fig. 2, two physical pixels a and physical pixels b adjacent in rows are arranged with a first virtual pixel disposed therebetween, and the first virtual pixel multiplexes the physical pixels a and the physical pixels b to determine pixel information of the first virtual pixel from pixel information of the physical pixels a and pixel information of the physical pixels b, so that a first virtual pixel array as shown in fig. 3 can be obtained, wherein the first virtual pixel array includes virtual pixels denoted with numeral 2.
Each of the second virtual pixels in the second virtual pixel array is located between two adjacent physical pixels in the column direction, and pixel information of the second virtual pixel is determined based on pixel information of the two physical pixels used to determine the virtual pixel, and for any two adjacent physical pixels in the column direction in the display screen, a second virtual pixel is disposed between the two physical pixels. The second virtual pixel may multiplex all solid-state chips in the two physical pixels, or multiplex part of the solid-state chips in the two physical pixels, the number of the multiplexed solid-state chips of the two physical pixels is the same, and the solid-state chip to which the two physical pixels are multiplexed is the solid-state chip closest to the virtual pixel position of the second virtual pixel according to the positional relationship. For example, as shown in fig. 4, a second virtual pixel is arranged between a physical pixel c and a physical pixel d which are adjacent in columns, and the second virtual pixel multiplexes a blue solid chip and a green solid chip in the physical pixel c, and a red physical chip and a green physical chip in the physical pixel d, and the pixel information of the second virtual pixel is determined by the pixel information of the blue solid chip and the green solid chip in the physical pixel c, and the pixel information of the blue solid chip and the green solid chip in the second virtual pixel multiplexing physical pixel c, so that a second virtual pixel array as shown in fig. 4 can be obtained, wherein the second virtual pixel array includes a virtual pixel represented by numeral 3.
Each third virtual pixel in the third virtual pixel array is located in the center of a rectangular display area formed by a first physical pixel, a second physical pixel adjacent to the first physical pixel in the row direction, a third physical pixel adjacent to the first physical pixel in the column direction and a fourth physical pixel adjacent to the second physical pixel in the row direction, wherein the fourth physical pixel is adjacent to the third physical pixel in the row direction; a third virtual pixel is arranged in the center of the area of a matrix area formed by any four physical pixels meeting the relationship. The third virtual pixel multiplexes all the solid chips in the first physical pixel, the second physical pixel, the third physical pixel and the fourth physical pixel, or multiplexes a part of the solid chips in the first physical pixel, the second physical pixel, the third physical pixel and the fourth physical pixel, wherein the solid chip multiplexed by the first physical pixel, the second physical pixel, the third physical pixel and the fourth physical pixel is the solid chip closest to the virtual pixel position of the third virtual pixel according to the position relationship, and the number of the solid chips multiplexed by the first physical pixel, the second physical pixel, the third physical pixel and the fourth physical pixel is the same. For example, as shown in fig. 5, a third virtual pixel is arranged in the center of the area of the rectangular area formed by the physical pixel a, the physical pixel B, the physical pixel C, and the physical pixel D, and the third virtual pixel multiplexes the green solid chip and the red physical chip in the physical pixel a, the green solid chip and the red physical chip in the physical pixel B, the green solid chip and the blue solid chip in the physical pixel C, and the green solid chip and the blue solid chip in the physical pixel D, and the pixel information of the green solid chip and the red physical chip in the physical pixel B, the pixel information of the green solid chip and the blue solid chip in the physical pixel C, and the pixel information of the green solid chip and the blue solid chip in the physical pixel D are used to determine the pixel information of the third virtual pixel, so that a third virtual pixel array as shown in fig. 5 can be obtained, wherein the third virtual pixel array includes virtual pixels represented by numeral 4. Thus, a third virtual pixel is formed by multiplexing 4 red physical chips, 2 green solid-state chips, and 2 blue solid-state chips. The problem that the display effect of the third virtual pixel is poor due to poor red light emitting efficiency can be solved.
Based on this, the arrangement relationship between the virtual pixel arrays corresponding to the display screen and the solid-state physical pixel array in the display screen may be as shown in fig. 6, where a numeral 1 represents a physical pixel, a numeral 2 represents a first virtual pixel, a numeral 3 represents a second virtual pixel, and a numeral 4 represents a third virtual pixel. When a picture to be displayed is divided based on the solid-state resolution of the display screen, the picture to be displayed can be divided based on the solid-state physical pixel array and the position information of each virtual pixel array in the display screen, wherein the dividing process can specifically determine the number of sub-pixel pictures which divide the picture to be displayed for determining the resolution of the picture to be displayed and the solid-state resolution of the display screen, wherein the number is less than or equal to 4, the solid-state physical pixel array and the target virtual pixel array which are used for displaying the picture to be displayed are selected based on the number, the array formed by the selected solid-state physical pixel array and the target sequence pixel array is matched with the array formed by the display pixel points of the picture to be displayed, the picture formed by the display pixel points which are matched with the physical pixels in the solid-state physical pixel array in the picture to be displayed serves as a candidate picture, and the picture formed by the display pixel points which are matched with the virtual pixels in the target virtual pixel array serves as a reference picture.
For example, the following steps are carried out: the solid-state resolution of the display screen is 256 × 256, the resolution of the picture to be displayed is 256 × 512, the number of sub-pixel pictures divided by the picture to be displayed is 2, the first virtual pixel matrix is used as a target virtual pixel array corresponding to the picture to be displayed, the picture formed by the display pixels of the picture to be displayed in the first column, the third column and the fifth column is used as a candidate picture, and the picture formed by the display pixels of the display picture in the second column, the fourth column and the sixth column is used as a reference picture. For another example, the solid-state resolution of the display screen is 2k, the resolution of the to-be-displayed picture is 4k, the number of sub-pixel pictures divided from the to-be-displayed picture is 3, the first virtual pixel array, the second virtual pixel array and the third virtual pixel array are all used as target virtual pixel arrays corresponding to the to-be-displayed picture, a picture formed by display pixel points located at the position corresponding to the number 1 in fig. 6 of the to-be-displayed picture is used as a candidate picture, a picture formed by display pixel points located at the position corresponding to the number 2 in fig. 6 of the to-be-displayed picture is used as a reference picture, a picture formed by display pixel points located at the position corresponding to the number 3 in fig. 6 of the to-be-displayed picture is used as a reference picture, and a picture formed by display pixel points located at the position corresponding to the number 4 in fig. 6 of the to-be-displayed picture is used as a reference picture.
And S20, lightening the display screen based on the candidate picture to display the candidate picture.
Specifically, lighting the display screen based on the candidate picture refers to lighting physical pixels in the display screen to display the candidate picture through the physical pixels in the display screen, where the display screen may be turned on by turning on and off, and it can be understood that the physical pixels in the display screen are powered on at a first power-on time to light each physical pixel, and each physical pixel corresponds to one display pixel in the candidate picture, and each physical pixel displays pixel information of its corresponding display pixel, where the pixel information includes a red pixel value, a green pixel value, and a blue pixel value, a color value of a red solid chip in the physical pixels corresponds to the red pixel value, a color value of the green solid chip corresponds to the green pixel value, and a color value of the blue solid chip corresponds to the blue pixel value.
S30, determining pixel information of virtual pixel arrays corresponding to the reference pictures, and sequentially lighting the display screen based on the reference pictures according to a time sequence to display the virtual pictures corresponding to the reference pictures through the virtual pixel arrays corresponding to the reference pictures so that the display screen displays the picture to be displayed, wherein the positions of the virtual pixels in the virtual pixel arrays corresponding to the reference pictures in the display screen are different.
Specifically, sequentially lighting the display screen based on each reference picture means that physical pixels in the display screen are sequentially controlled to be lit, and each time a physical pixel in the display screen is lit, the pixel information displayed by the physical pixel is the pixel information of a display pixel point in the reference picture corresponding to the lighting.
