Liquid crystal display panel and drive method thereof

Abstract

A liquid crystal display panel comprises: a plurality of scanning lines, a plurality of data lines, a data driven circuit, a gray level processor and a memory. The minimal area enclosed by the data line and scanning line is defined as one pixel unit. The gray level processor receives the j(j>=1), j+1, k-1(j+2<=k<=h, h<=frame frequency), k frame gray level voltage from outside. When the j+1 frame of the pixel unit displays dynamic menu, and when the gray level voltage difference of the j and j+1 frames of the pixel unit is less than the gray level voltage difference of the j and k frames of the pixel unit, therefore the gray level voltages of the j+1 frame and k frame are exchanged. The memory stores the treated gray level output from the gray level processor and untreated residual gray level voltage output from the outside device, and the equal gray level voltages are output to the data driven circuit in turn. The liquid crystal display panel can improve the streaking phenomena of displaying dynamic menu.

Description

technical field [0001] The invention relates to a liquid crystal display panel and a driving method thereof. Background technique [0002] Due to the advantages of lightness, thinness, and low power consumption, liquid crystal display panels are widely used in modern information equipment such as televisions, notebook computers, mobile phones, and personal digital assistants. At present, the application of liquid crystal display panel televisions in the market is becoming more and more important. However, liquid crystal itself is a material with a viscosity coefficient, so its response speed cannot compete with cathode ray tube (Cathode Radial Tube, CRT) displays. [0003] Please refer to FIG. 1 , which is a schematic diagram of a liquid crystal display panel in the prior art. The liquid crystal display panel 10 includes a plurality of scanning lines 13 parallel to each other, a plurality of data lines 14 insulated and perpendicularly intersecting the scanning lines 13 , a ...
