Image display driving method for LCD device

Abstract

An image display driving method of a liquid crystal display device includes the following procedures: a data conversion program is to convert a first sub-image frame data and a second sub-image frame data into the first sub-image required to drive a pixel respectively A pre-voltage signal and a post-voltage signal of the frame data and a pre-voltage signal and a post-voltage signal of the frame data of a second sub-image; the display driver is to convert the first sub-image within a frame time The pre-voltage signal and post-voltage signal of a sub-image frame data, and the pre-voltage signal and post-voltage signal of the second sub-image frame data are sequentially written into the pixels; the light source control program is to control a first The brightness of the light source of a light-emitting unit is such that it presents a first average brightness within the corresponding time period when the pre-voltage signal of the first sub-image frame data is written into the pixel, and the post-voltage signal of the first sub-image frame data A second average luminance greater than the first average luminance is exhibited for a corresponding time of writing to the pixel.

Description

technical field [0001] The present invention relates to an image display driving method of a display device, in particular to an image display driving method of a liquid crystal display device capable of eliminating blurring phenomenon. Background technique [0002] The liquid crystal display device can be roughly divided into a liquid crystal display device used as a general display screen and a liquid crystal display device used as a television in terms of its application. In fact, the basic structures of the two liquid crystal display devices are not very different, but only some components and circuits are different, and some components are arranged in different positions. [0003] Such as figure 1 As shown, the existing liquid crystal display device mainly includes a liquid crystal display panel 1 , a backlight module 2 , a driving circuit 3 , and a control circuit 4 . The liquid crystal display panel 1 at least includes a liquid crystal layer 11 , a color filter subs...

AI Technical Summary

Problems solved by technology

[0008] It can be seen that the image display driving method of the above-mentioned existing liquid crystal display device cannot completely improve the blur phenomenon no matter whether it is to use a fast-response liquid crystal, to use an over-excitation drive technology, or to add an intermittent driving backlight module technology.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general method has no suitable method to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
