A method and system for driving a liquid crystal display panel

Abstract

The invention discloses a liquid crystal display panel driving method and a liquid crystal display panel driving system and relates to the technical field of liquid crystal display with an aim to solve the problem that image display quality is affected due to large load that input signals bear. The liquid crystal display panel driving method includes: dividing display region into multiple subregions of a liquid crystal display panel horizontally and sequentially completing charging on a first sub-pixel, a second sub-pixel and a third sub-pixel of the subregions for certain row of the sub-pixels, wherein the first sub-pixel, the second sub-pixel and the third sub-pixel are different and respectively refer to one of an R sub-pixel, a G sub-pixel and a B sub-pixel. By the arrangement, the input signals corresponding to the display subregions are enabled to be small, and display quality of a display is guaranteed.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method and system for driving a liquid crystal display panel. Background technique [0002] With the rapid development of the small and medium-sized electronic display industry, people have higher and higher requirements for the resolution quality of small and medium-sized LCD liquid crystal display screens. The improvement of the display quality is closely related to the transmission rate of the display data and the integrity of the signal. Generally speaking, there are two types of drive signals provided to the LCD liquid crystal display, namely: the gate drive signal (Gate signal) input to the LCD liquid crystal display and the source drive signal (Source signal) input to the LCD liquid crystal display ). [0003] figure 1 A schematic diagram of a signal driving architecture of a small and medium-sized LCD display screen commonly used at present is shown. ...

AI Technical Summary

Problems solved by technology

[0006] However, the defect of the driving method of the liquid crystal display panel in the prior art is that: when the input signal is turned on, all the R sub-pixels, G sub-pixels or B sub-pixels in the display area are charged at one time, so that the input signal bears The load is too large

As a result, the input signal will deviate instantaneously, resulting in poor quality of the input signal to the LCD panel, thereby affecting the quality of the screen display
