and S11, determining a first gray level threshold according to the characteristics of the rotating display screen.
In other words, the first gray scale threshold is different for different rotating display screens due to different characteristics (different manufacturing processes, different acting materials, etc.). If the gray scale level of the pixel is divided into 0 gray scale to 255 gray scale, the first gray scale threshold is generally a low gray scale, for example, below 60 gray scale.
It should be noted that the rotation process of the rotating display screen is shown in fig. 4a to 5b, wherein the dotted line 1 in fig. 4b represents the rotation axis, and the number in fig. 5b represents the phase.
And S12, comparing the gray value of the lighted pixel in the image of the current phase with the first gray threshold value.
In other words, the gray scale value of the pixel lighted in the image of the current phase is screened by taking the first gray scale threshold value as a reference.
S13, if the gray value of the pixel to be turned on in the image of the current phase is smaller than the first gray level threshold, setting the pixel as a pixel to be adjusted (indicated by O in fig. 4b and 6), adjusting the gray level value of the pixel to be adjusted to zero gray level, and performing gray level compensation on the pixel close to the pixel to be adjusted.

It should be noted that, in this embodiment, each phase of the rotating display panel has an image, and if the rotating display panel is required to display a stationary stereoscopic image, each image is an image formed by lines, so that when the rotating display panel starts to rotate for display, a stereoscopic image can be displayed. Therefore, the number of pixels lit up in each image is relatively small.
In the method for adjusting the display image of the rotating display screen, the pixels with low gray scale and the pixels near the pixels are subjected to gray scale compensation, so that color cast of the pixels with low gray scale can be avoided, and the image quality of the image displayed by the rotating display screen can be improved under the principle of visual residual, so that the rotatably displayed three-dimensional image can be more natural.
Example 2:

and S21, determining a first gray level threshold according to the characteristics of the rotating display screen.
In other words, the first gray scale threshold is different for different rotating display screens due to different characteristics (different manufacturing processes, different acting materials, etc.). If the gray scale level of the pixel is divided into 0 gray scale to 255 gray scale, the first gray scale threshold is generally a low gray scale, for example, below 60 gray scale.
Specifically, the first grayscale threshold is 40 grayscales to 60 grayscales, preferably 50 grayscales.
It should be noted that the rotation process of the rotating display screen is shown in fig. 4a to 5b, wherein the dotted line 1 in fig. 4b represents the rotation axis, and the number in fig. 5b represents the phase. The axis of rotation for rotating the display screen may be centered on the row of pixels of the display screen or may be located at the first column of pixels. The display screen adjustment method of the rotating display panel according to the present embodiment is described by taking the case where the rotation axis may be located at the center of the line pixel of the display panel as an example.
In addition, the rotary display screen of the present embodiment may be a flat display screen or a curved display screen.
And S22, comparing the gray value of the lighted pixel in the image of the current phase with the first gray threshold value.
In other words, the gray scale value of the pixel lighted in the image of the current phase is screened by taking the first gray scale threshold value as a reference.
S23, if the gray level of the pixel to be adjusted in the image of the current phase is smaller than the first gray level threshold, the pixel is the pixel to be adjusted (indicated by O in fig. 4b and fig. 6), the gray level of the pixel to be adjusted is adjusted to zero gray level (corresponding to black), and gray level compensation is performed on the pixel close to the pixel to be adjusted, so as to reduce the color cast generated by the pixel to be adjusted.

Therefore, the number of the pixels lighted in each image is relatively small, and therefore, in the method for adjusting the display frame of the rotating display screen according to the embodiment, the color cast caused by low gray scale can be avoided only by compensating the gray scale of the pixels to be adjusted 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 adjacent in the current phase is increased by Y1, Y1 ═ kx1+ d, x1 ═ a (G-z)/(2a +2b +4 c); increasing the gray-scale value of the pixel having the same position as the pixel to be adjusted in the previous phase and the gray-scale value of the pixel having the same position as the pixel to be adjusted in the subsequent phase by Y2, Y2 kx2+ d, x 2b (G-z)/(2a +2b +4 c); increasing the gray-scale value of the pixel which is in the same column and adjacent to the pixel to be adjusted in the current phase and the pixel which is in the same column and adjacent to the pixel to be adjusted in the current phase by Y3, wherein the gray-scale value of the pixel which is in the same column and adjacent to the pixel to be adjusted in the current phase is Y3 ═ kx3+ d, wherein x3 ═ c (G-z)/(2a +2b +4 c); wherein a denotes a distance (Pitch) between pixels of adjacent rows in the same phase, b denotes a distance between the same pixels of adjacent phases,
g represents the value of the first gray level threshold, z represents the image to be adjustedThe gray value before the pixel was adjusted.
It should be noted that when b represents the distance between the same pixels of the adjacent phases, then b is α r, α represents the angle between the current phase and the adjacent phase, r represents the distance between the pixel to be adjusted and the rotation axis, and r can be calculated according to the position of the pixel to be adjusted and a.
If the angle α is small (e.g., 1 °), a and b are perpendicular and b is approximately a straight line
Representing the distance between the pixel to be adjusted and the pixel that is in the same column as 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 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 and adjacent to the pixel to be adjusted in the previous phase, and a, b, and c correspond to a, b, and c in the above formula, respectively. The pixel positions of the latter phase are similar to those described above and will not be described in detail.
S24, if the gray scale value of the pixel lighted in the image of the current phase is greater than or equal to the first gray scale threshold, the gray scale value of the pixel lighted in the image of the current phase remains unchanged.
