LIQUID CRYSTAL DISPLAY DEVICE AND DISPLAY DRIVING METHOD THEREOF

摘要

A liquid crystal display device and a display driving method thereof are provided. A first data signal is provided firstly, and a driving control signal is generated according to the first data signal. According to the positive and negative polarities of the inputted pixel voltages corresponding to the first to Nth pixels in a group of pixel column, the driving control signal divides the first to Nth pixels into a first pixel group and a second pixel group. According to the driving control signal, scanning signals are provided orderly to the pixels of the first pixel group for opening the pixels of the first pixel group one by one to input pixel voltages. Then scanning signals are provided orderly to the pixels of the second pixel group for opening the pixels of the second pixel group one by one to input pixel voltages, thus the display of a frame image is accomplished. The liquid crystal display device and the display driving method thereof can not only improve the display quality by the polarity inversion, but also save the power consumption.
