Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] Due to the long-term driving in the direct current mode, the liquid crystal panel will experience aging phenomenon of liquid crystal molecules, which seriously affects the life of the liquid crystal panel. Therefore, the liquid crystal panel is generally driven by an AC drive mode. Furthermore, the liquid crystal layer is equivalent to a capacitor in terms of circuit equivalent, and its signal will be different due to the influence of positive and negative h...

Abstract

The embodiment of the invention discloses picture regulating method and device of a liquid crystal panel, relating to the technical field of liquid crystal display and aims to increase picture display effect of the liquid crystal panel. The picture regulating method comprises the following steps of: selecting a test picture; regulating a blink value of the test picture to obtain a critical public reference voltage; obtaining a gray-scale picture; and regulating a gamma curve of the gray-scale picture to obtain a critical source electrode driver voltage. The invention can increase the picture display effect of the liquid crystal panel.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method and device for adjusting a picture of a liquid crystal panel. Background technique [0002] Large-size flat-panel LCD TVs are increasingly favored by many consumers, and consumers have higher and higher requirements for display images and picture quality. [0003] Due to the inherent characteristics of liquid crystal molecules, liquid crystal displays need to constantly change the positive and negative polarities when displaying pictures, so it is easy to cause a large difference in the absolute value of the positive and negative gray scale voltages in different pictures, so that the human eye can see the difference in different pictures. The degree of screen shake felt under the screen is also different. In addition, due to the characteristics of the liquid crystal display itself, there is a certain distortion between the input voltage and the output ima...
