Embodiment 1

[0033] Such as Figure 2 to Figure 6 As shown, this embodiment provides a method for adjusting the display screen of a rotating display screen. The rotating display screen includes a plurality of pixels distributed in an array. Rotation, and each rotation of a specific angle is a phase, rotating the display screen in different phases to display different images to achieve stereoscopic display, the display image adjustment methods include:

[0034] S11. Determine a first gray scale threshold according to the characteristics of the rotating display screen.

[0035] Wherein, that is to say, different rotating display screens have different first grayscale thresholds due to their different characteristics (differences in manufacturing process, working materials, etc.). If the grayscale of the pixel is divided into grayscale 0 to grayscale 255, the first grayscale threshold is generally a low grayscale, such as below 60 grayscale.

[0036] It should be noted that the rotation pro...

Embodiment 2

[0044] Such as Figure 2 to Figure 6 As shown, this embodiment provides a method for adjusting the display screen of a rotating display screen. The rotating display screen includes a plurality of pixels distributed in an array. Rotation, and each rotation of a specific angle is a phase, rotating the display screen in different phases to display different images to achieve stereoscopic display, the display image adjustment methods include:

[0045] S21. Determine a first gray scale threshold according to the characteristics of the rotating display screen.

[0046] Wherein, that is to say, different rotating display screens have different first grayscale thresholds due to their different characteristics (differences in manufacturing process, working materials, etc.). If the grayscale of the pixel is divided into grayscale 0 to grayscale 255, the first grayscale threshold is generally a low grayscale, such as below 60 grayscale.

[0047] Specifically, the first grayscale thresh...

Embodiment 3

[0065] Such as Figure 7 As shown, this embodiment provides a display screen adjustment device for a rotating display screen. The rotating display screen includes a plurality of pixels distributed in an array. Rotation, and each rotation of a specific angle is a phase, rotating the display screen in different phases to display different pictures to achieve stereoscopic display, the adjustment device includes:

[0066] An acquisition unit, configured to determine the first gray scale threshold according to the characteristics of the rotating display screen;

[0067] A comparing unit, configured to compare the grayscale value of the lit pixel in the image of the current phase with the first grayscale threshold;

[0068] An adjustment unit, configured to, if the grayscale value of the lit pixel in the image of the current phase is less than the first grayscale threshold, set the pixel as the pixel to be adjusted, adjust the grayscale value of the pixel to be adjusted to zero gra...

Abstract

The invention provides a display picture adjusting method and device of a rotary display screen and the rotary display screen, belongs to the technical field of display, and can at least partially solve the problem of color cast of an existing rotary display screen due to low gray scale pixels. The invention discloses a method for adjusting a display image of a rotary display screen, wherein the rotary display screen comprises a plurality of pixels distributed in an array and can rotate at a specific angular speed by taking a line which is parallel to the column pixels and passes through the rotary display screen as an axis, the rotary display screen displays different pictures in different phases, and the method comprises the following steps: determining a first gray-scale threshold valueaccording to the characteristics of the rotary display screen; comparing the gray value of the lightened pixel in the image of the current phase with a first gray scale threshold value; and if the gray value of the lightened pixel in the image of the current phase is smaller than the first gray scale threshold value, taking the pixel as a to-be-adjusted pixel, adjusting the gray scale value of the to-be-adjusted pixel to zero gray scale, and performing gray scale compensation on the pixel close to the to-be-adjusted pixel.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a method and device for adjusting a display screen of a rotating display screen, and a rotating display screen. Background technique [0002] A rotating display screen in the prior art includes a plurality of pixels distributed in an array. The rotating display screen can be rotated at a specific angular speed on the axis parallel to the column of pixels and passing through the rotating display screen, and each rotation of a specific angle is a phase. , the rotating display screen displays different pictures in different phases, so as to realize stereoscopic display. [0003] However, if figure 1 As shown, during the display process of this kind of rotating display screen, because the gray scale value of the pixel is too small, serious color shift of the display screen will occur, thereby affecting the display screen. Contents of the invention [0004] The presen...
