Abstract

The embodiment of the invention provides a method and device for eliminating ghost shadows and a storage medium. The method and device are applied to electronic equipment using a liquid crystal technology. The method comprises the following steps: when it is detected that the duration of displaying the current picture by the liquid crystal screen meets a first preset condition, adjusting the signal amplitude of the image signal transmitted to the liquid crystal screen according to the first preset adjustment trend, and adjusting the backlight brightness of the liquid crystal screen according to the first adjustment amount of the signal amplitude and the second preset adjustment trend, wherein the adjustment direction of the first preset adjustment trend is opposite to the adjustment direction of the second preset adjustment trend. The purpose of avoiding displaying the same picture for a long time is achieved by adjusting the signal amplitude of the image signal transmitted to the liquid crystal screen and the backlight brightness of the liquid crystal screen, so the ghosting phenomenon of the liquid crystal screen is eliminated, and the protection mode of the liquid crystal screenis realized under the condition of not changing the picture display effect.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a method, device and storage medium for eliminating image sticking. Background technique [0002] In the field of display technology, liquid crystal technology and its derivative technologies show strong development potential. However, there is still a non-negligible defect in liquid crystal technology: when products using liquid crystal technology, such as LCD screens, work in one state for a long time, the characteristics of the liquid crystal molecules themselves will cause afterimages to appear when switching screens. question. [0003] In order to achieve the purpose of eliminating the afterimage, the related technology solves the afterimage problem by regularly moving the picture. But for some pixels on the LCD screen, when there is no change before and after the moving screen, afterimages will still exist for these pixels. Contents of the in...
