Problems solved by technology

In the backlight module using this method of periodically driving the light source, although the problem of blurring of the moving picture can be prevented to a certain extent, due to the use of a light source with phosphors, the luminescence phenomenon of the phosphors will not be visible after the light source is stopped. Still lasts for a short period of time, so can still cause issues with afterglow or afterimages

Abstract

The application relates to a method for eliminating image sticking, a circuit for eliminating image sticking, and a display device. The method for eliminating image sticking provided by the application is used in a display, and the display has a backlight source and a display panel, and the backlight source has a phosphor coating , the method comprises the following steps: at the moment when the backlight is powered off, detect the RGB values ​​of each display area of ​​the residual image on the display panel, generate a compensation image according to the residual image, and make the RGB values ​​of each display area of ​​the compensation image, The sum of the RGB values ​​of each display area of ​​the residual image is the original RGB value of the display area; and the display panel displays the compensation image, and the display time of the compensation image is a predetermined time length. The present application can eliminate the afterglow or afterimage existing in the existing display device by outputting a compensation picture with a certain gray scale, and improve the display quality.

Description

technical field [0001] The present application relates to the technical field of displays, and in particular to an afterimage elimination method, an afterimage elimination circuit and a display device. Background technique [0002] Afterimage, in the field of photoelectric display, mainly refers to the residual image on the display, that is, when the display is switched or turned off, the previously displayed image will not disappear immediately, but will gradually disappear. [0003] In the method of periodically driving the light emitting sources, generally speaking, while driving each pixel on the liquid crystal panel in a timely manner, these light emitting sources are periodically driven sequentially in accordance with the configured multiple light emitting sources, so that the backlight module partially Provides light to the LCD panel. In this way, the problem of motion blur caused by dynamic picture display can be prevented. In the backlight module using this method...
