Abstract

The invention relates to a liquid crystal display device and a driving method thereof. The liquid crystal display device comprises a liquid crystal display panel comprising a plurality of scanning lines, a plurality of data lines, a plurality of thin film transistors and a plurality of pixel electrodes; a scanning drive circuit used for driving the scanning lines; a data drive circuit used for driving the data lines, a specific gray level picture drive circuit used for providing the voltage signal of a specific gray level for the pixel electrodes; a short circuit drive circuit used for causing short circuit between at least part of data lines in the data lines; and a control circuit used for controlling the scanning drive circuit, the data drive circuit, the specific gray level drive circuit and the short circuit drive circuit. The liquid crystal display device and the driving method play very effective protection functions to heat damage caused by a black (gray) frame insertion manner.

Description

Technical field [0001] The present invention relates to a liquid crystal display device and a driving method thereof, in particular to a liquid crystal display device and a driving method thereof that can be inserted into a specific gray scale picture. Background technique [0002] With the advent of the high-definition television era, the application of liquid crystal displays has become more and more popular. The liquid crystal display uses an electric field to control the light transmittance of the liquid crystal with dielectric anisotropy, thereby displaying images. The liquid crystal display includes a liquid crystal display panel having a matrix of pixel units and a driving circuit for driving the liquid crystal display panel. [0003] figure 1 Is the circuit diagram of the prior art liquid crystal display, such as figure 1 As shown, the liquid crystal display includes: a liquid crystal display panel 10 including a plurality of scan lines GL and a plurality of data lines...
