Method for improving liquid crystal display image sticking and liquid crystal display driving device

Abstract

The embodiment of the invention relates to a method for improving liquid crystal display image sticking and a liquid crystal display driving device. The method for improving the liquid crystal display image sticking comprises the following steps: judging whether a first image in refresh display on a liquid crystal display within a preset time changes or not; and if not, controlling a second imageto be in refresh display on the liquid crystal display after the preset time so as to improve the image sticking caused by the long-term refresh display of the first image. As for the method and the device provided by the embodiment of the invention, the residual direct current voltage of the first image after long-term display can be reduced by inserting to display the second image opposite to the first image after the first image is displayed for a long term, thus improving the image sticking in liquid crystal display and enhancing the image display quality of the liquid crystal display.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for improving afterimages of liquid crystal display and a driving device for liquid crystal display. Background technique [0002] Thin film transistor liquid crystal display (abbreviated as TFT LCD), as a major mainstream in the display market, has been widely used in many aspects such as televisions and computer monitors. Liquid crystal panel is the main component of TFT LCD, which is composed of color film substrate, TFT array substrate, liquid crystal, sealant and alignment layer. [0003] Liquid crystal display has many disadvantages such as tailing, slow response speed, afterimage, etc. Among them, afterimage has a very important impact on the quality of TFT LCD. figure 1 It is a schematic diagram of picture one displayed by TFT LCD in the prior art, figure 2 It is a schematic diagram of the second picture to be displayed by the TFT LCD in the pri...

AI Technical Summary

Problems solved by technology

However, on the one hand, the ion concentration in the existing liquid crystal material and the material of the alignment layer is already very low, and it is very difficult to further reduce its concentration on this basis; on the other hand, because the liquid crystal material is a mixture of many kinds of liquid crystals, it is also difficult It is very difficult to further improve the afterimage through theoretical analysis by analyzing the interaction among them and the interaction between various components in the liquid crystal material and the alignment layer or the sealant.
