Abstract

The invention provides an LCD device, which comprises a time sequence controller. The time sequence controller comprises a frame data analysis circuit and a circuit for generating dynamic polarity reversion data. The frame data analysis circuit analyzes the luminous status of each pixel unit in a frame of video signals; the circuit for generating dynamic polarity reversion data correspondingly determines the polarity of each pixel unit so as to ensure that all the horizontal polarity exchange frequencies of the polarity of the voltage loaded on all pixels in luminous status in each line of each frame of image are larger than the horizontal flashing frequency of human eyes, and ensure that all the vertical polarity exchange frequencies of the polarity of the voltage loaded on all pixels inluminous status in each line are larger than the vertical flashing frequency of the human eyes. The invention further provides a method for driving the LCD device.

Description

technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof. Background technique [0002] Please refer to FIG. 1 , which is a schematic diagram of a prior art liquid crystal display device. The liquid crystal display device 100 includes a liquid crystal panel 10, a timing controller 11, a scanning driver 12, a data driver 13, a plurality of rows of scanning lines G1-Gn (n>1) parallel to each other, and a plurality of columns parallel to each other and respectively The multiple rows of scan lines G1 ˜ Gn are insulated from intersecting data lines D1 ˜ Dm (m>1). The multi-row scanning lines G1-Gn and the multi-column data lines D1-Dm divide the liquid crystal panel 10 into a plurality of pixels 101, and the equivalent circuit of each pixel 101 mainly includes a thin film transistor (Q11-Qnm) and a liquid crystal Capacitance (C11 ~ Cnm). The gates of the thin film transistors (Q11~Qnm) are connected to the scanning line...
