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 grayscale compensation method and device, and a display device. The gray scale compensation method includes obtaining the basic gray scale of each compensation unit; obtaining the equivalent lighting time of each compensation unit, the equivalent lighting time being the compensation unit obtained by converting the actual lighting time of the compensation unit to the preset gray When the equivalent duration reaches any preset time point, according to the preset time point and the basic gray scale, look up the table to obtain the gray scale compensation parameters corresponding to the compensation unit. According to the gray scale compensation parameters and the basic gray scale , performing gray scale compensation on the sub-pixels in the compensation unit. The technical solution provided by the embodiment of the present invention has high compensation accuracy and no overcompensation phenomenon, and thus does not need to solve the overcompensation problem after the grayscale compensation operation, which is beneficial to simplify the grayscale compensation process.

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...
