Example 1:
as shown in fig. 2 to 6, the present embodiment provides a display screen adjustment method of a rotary display screen, the rotary display screen includes a plurality of pixels distributed in an array, the rotary display screen can rotate at a specific angular velocity with a line parallel to a column of pixels and passing through the rotary display screen as an axis, and each rotation has a specific angle as a phase, and the rotary display screen displays different images in different phases to realize stereoscopic display, the display screen adjustment method includes:
s11, determining a first gray level threshold according to the characteristics of the rotary display screen.
In other words, the first gray-scale threshold value is different for different rotary display screens due to different characteristics (different preparation processes, different action materials, etc.). If the gray level of the pixel is classified into 0 gray level to 255 gray levels, the first gray level threshold is generally low gray level, for example, 60 gray levels or less.
It should be noted that, in the rotation process of the rotating display screen, as shown in fig. 4a to 5b, the broken line 1 in fig. 4b represents the rotation axis, and the number in fig. 5b represents the phase.
S12, comparing the gray value of the lighted pixel in the current phase image with a first gray threshold value.
The gray value of the lighted pixel in the current phase image is screened by taking the first gray threshold value as a reference.
And S13, if the gray level of the lighted pixel in the image of the current phase is smaller than the first gray level threshold, the pixel is taken as the pixel to be regulated (shown by the O point in fig. 4b and 6), the gray level of the pixel to be regulated is regulated to zero gray level, and gray level compensation is carried out on the pixel close to the pixel to be regulated.
In other words, the gray scale of the pixel in the vicinity of the pixel is compensated according to the gray scale value of the lighted pixel in the image of the current phase.
It should be noted that, in this embodiment, each phase of the rotary display screen has an image, and if the rotary display screen is required to display a still stereoscopic image, each image is an image formed by lines, so that when the rotary display screen starts to rotate, a stereoscopic image can be displayed. Therefore, the number of pixels lit in each image is relatively small.
In the display screen adjustment method of the rotary display screen of the embodiment, the pixels with low gray scale and the pixels near the pixels are subjected to gray scale compensation, so that color shift of the pixels with low gray scale can be avoided, and the image quality of the screen displayed by the rotary display screen can be improved by utilizing the vision residual principle, so that the stereoscopic image displayed by rotation can be more natural.

s21, determining a first gray level threshold according to the characteristics of the rotary display screen.
In other words, the first gray-scale threshold value is different for different rotary display screens due to different characteristics (different preparation processes, different action materials, etc.). If the gray level of the pixel is classified into 0 gray level to 255 gray levels, the first gray level threshold is generally low gray level, for example, 60 gray levels or less.
Specifically, the first gray level threshold is 40 gray levels to 60 gray levels, preferably 50 gray levels.
It should be noted that, in the rotation process of the rotating display screen, as shown in fig. 4a to 5b, the broken line 1 in fig. 4b represents the rotation axis, and the number in fig. 5b represents the phase. The rotation axis of the rotating display screen may be located at the center of the row pixels of the display screen or at the top row pixels. The display screen adjustment method of the rotary display screen of the present embodiment may be described by taking the center of a row pixel located in the display screen as an example.
In addition, the rotary display screen of the present embodiment may be a flat display screen or a curved display screen.
S22, comparing the gray value of the lighted pixel in the current phase image with a first gray threshold value.
The gray value of the lighted pixel in the current phase image is screened by taking the first gray threshold value as a reference.
S23, if the gray level of the lighted pixel in the current phase image is smaller than the first gray level threshold, the pixel is taken as the pixel to be regulated (shown by the O point in fig. 4b and 6), the gray level of the pixel to be regulated is regulated to zero gray level (corresponding to black), and gray level compensation is carried out on the pixel close to the pixel to be regulated, so that the color shift generated by the pixel to be regulated is reduced.
In other words, the gray scale of the pixel in the vicinity of the pixel is compensated according to the gray scale value of the lighted pixel in the image of the current phase.

Therefore, the number of the pixels lighted in each image is relatively small, so in the display screen adjusting method of the rotary display screen of the embodiment, the color shift generated by low gray scale can be avoided only by compensating the gray scale of the pixels according to the pixels to be adjusted.
Specifically, the gray-scale value of the pixel which is in the same column as the pixel to be adjusted and is adjacent to the pixel to be adjusted in the current phase is increased by Y1, y1=kx1+d, x1=a (G-z)/(2a+2b+4c); increasing the gray-scale value of the pixel in the previous phase, which is the same as the pixel position to be adjusted, and the pixel in the next phase, which is the same as the pixel position to be adjusted, by Y2, y2=kx2+d, x2=b (G-z)/(2a+2b+4c); increasing the pixel in the current phase in-line with and adjacent to the pixel to be adjusted and the pixel in the current phase in-line with and adjacent to the pixel to be adjusted by Y3, y3=kx3+d, where x3=c (G-z)/(2a+2b+4c); where a denotes a distance (Pitch) between adjacent rows of pixels in the same phase, b denotes a distance between the same pixels in adjacent phases,g represents the value of the first gray-scale threshold and z represents the gray-scale value before the pixel to be adjusted is adjusted.
It should be noted that, when b represents the distance between the same pixels of adjacent phases, then b=αr, α represents the angle between the current phase and the adjacent phase, and r represents the distance between the pixel to be adjusted and the rotation axis; and r can be calculated from the position of the pixel to be adjusted and a.
Further, if the angle of α is small (e.g., 1 °), a and b are perpendicular, and b is approximately a straight line, thenIndicating to be adjustedThe distance between a pixel and a pixel in the same column and adjacent to the pixel to be adjusted in the adjacent phase.
As shown in fig. 6, X1 represents the current phase, O represents the pixel to be adjusted, P represents the pixel in the same column as and adjacent to the pixel to be adjusted in the current phase, X2 represents the previous phase, Q represents the pixel in the same column as and adjacent to the pixel to be adjusted in the previous phase, and a, b, c correspond to a, b, c in the above formula, respectively. The pixel position of the latter phase is similar to the above and will not be described in detail.
And S24, if the gray value of the lighted pixel in the image of the current phase is larger than or equal to the first gray threshold value, the gray value of the lighted pixel in the image of the current phase is kept unchanged.
In the display screen adjustment method of the rotary display screen of the embodiment, the pixels with low gray scale and the pixels near the pixels are subjected to gray scale compensation, so that color shift of the pixels with low gray scale can be avoided, and the image quality of the screen displayed by the rotary display screen can be improved by utilizing the vision residual principle, so that the stereoscopic image displayed by rotation can be more natural.
