Liquid crystal module driving control method and device thereof and liquid crystal display

Abstract

The embodiment of the invention discloses a liquid crystal module driving control method and a device thereof and a liquid crystal display. A specific embodiment of the method comprises the followingsteps: a display brightness ratio between a positive polarity picture and a negative polarity picture displayed is obtained by the liquid crystal module under the same brightness level; according to the display brightness ratio, the driving parameter quantity of the liquid crystal module during positive polarity driving or negative polarity driving is adjusted, so that the display brightness of apositive polarity picture and the display brightness of a negative polarity picture displayed by the liquid crystal module under the same brightness level are the same. According to the embodiment, poor display such as flickering can be eliminated, and the display effect is improved.

Description

technical field [0001] This application relates to the field of display technology. More specifically, it relates to a liquid crystal module drive control method and device, and a liquid crystal display. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) is widely used in televisions, mobile phones, monitors and other electronic products due to its advantages of stable picture, vivid image, radiation elimination, space saving and energy saving. [0003] Flicker (Flicker) refers to the discontinuous (unstable) feeling produced by the viewer to the periodic change of light stimulus (such as brightness, etc.) under certain conditions. In the liquid crystal module, due to the characteristics of liquid crystal molecules, it cannot be kept at a constant voltage for a long time, otherwise its characteristics will be destroyed, so that the liquid crystal module cannot display normally. In order to solve the above problems, the prior art adopts a po...

AI Technical Summary

Problems solved by technology

In the liquid crystal module that adopts the polarity inversion driving method, due to the leakage of pixels in the TFT, capacitive coupling, etc., at the same brightness level, the deflection voltage applied to the liquid crystal molecules during positive polarity driving and negative polarity driving may be inconsistent. , which in turn causes inconsistencies in the deflection of the liquid crystal molecules during positive and negative driving, making the brightness inconsistent between positive and negative driving.

In the prior art, in the manufacturing process of the liquid crystal module, the method of adjusting the common voltage Vcom with a fixed adjustment value according to experience is used to minimize the inconsistency of the deflection voltage during positive polarity driving and negative polarity driving. Due to the limitation of material characteristics and manufacturing process, this method has limited effect on improving the flicker phenomenon
