Embodiment Construction

[0037] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the following is a specific implementation of a gray scale compensation method and device and display equipment proposed in accordance with the present invention in conjunction with the accompanying drawings and preferred embodiments. , structure, feature and effect thereof, detailed description is as follows.

[0038] An embodiment of the present invention provides a gray scale compensation method including:

[0039] Obtain the basic gray scale of each compensation unit;

[0040] Acquiring the equivalent lighting duration of each of the compensation units, the equivalent lighting duration is the duration of the compensation unit being lit in a preset gray scale obtained by converting the actual lighting duration of the compensation unit;

[0041] When it is judged that the equivalent duration reaches any preset time point, according to...

Abstract

The invention discloses a gray scale compensation method and device and display equipment. The gray scale compensation method comprises the steps of obtaining a basic gray scale of each compensation unit; obtaining the equivalent lighting duration of each compensation unit, wherein the equivalent lighting duration is the lighting duration of the compensation unit at a preset gray scale, which is obtained by converting the actual lighting duration of the compensation unit; when it is judged that the equivalent time reaches any preset time point, according to the preset time point and the basicgray scale, a table is looked up to obtain gray scale compensation parameters corresponding to the compensation unit, and according to the gray scale compensation parameters and the basic gray scale,gray scale compensation is performed on sub-pixels in the compensation unit. According to the technical scheme provided by the embodiment of the invention, the compensation precision is relatively high, an over-compensation phenomenon does not occur, the over-compensation problem does not need to be solved after gray scale compensation operation, and the gray scale compensation process is simplified.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a grayscale compensation method and device, and a display device. Background technique [0002] Organic light-emitting display panels have the advantages of self-illumination without backlight, low power consumption, and high brightness, and are widely used in various electronic devices and are favored by users. [0003] As the total display time continues to increase, problems such as threshold voltage drift of thin-film transistors and aging of light-emitting elements will appear in organic light-emitting display panels. The above problems limit the application of organic light-emitting display panels in vehicles and industrial control equipment with long lifespan. In the prior art, the compensation technology is used to solve the above problems. The timing compensation technology has the advantages of simple implementation, good flexibility, and wid...
