Abstract

The present invention relates to a data processing circuit, a liquid crystal display device and a drive method thereof. The data processing circuit comprises a frame scanning frequency selection circuit, a memory, a data selection circuit, a signal output circuit and a data analysis circuit; the image signals transmitted into the signal processing circuit are stored in the memory through the data analysis circuit; the data analysis circuit reads the image signals in the memory, and analyzes the brightness of the pixel of each frame and the polarity of the driving voltage of the frame pixel; the frame scanning frequency selection circuit controls the frame frequency of the image signals transmitted from the signal output circuit, according to the analytic results of the data analysis circuit; and the data selection circuit controls the image signals transmitted from the signal output circuit, according to the analytic results of the data analysis circuit. The data processing circuit can effectively improve the problem of flickering pictures in the liquid crystal display.

Description

Technical field [0001] The invention relates to a data processing circuit, a liquid crystal display device and a driving method thereof. Background technique [0002] Liquid crystal display devices are widely used in electronic display devices such as mobile phones, TVs, and notebook computers because of their low radiation and thin thickness. The current liquid crystal display device adopts frame inversion (Frame Inversion) driving, line inversion (Row Inversion) driving, row inversion (Column Inversion) driving and dot inversion (Dot Inversion) driving. Among them, the dot inversion driving application is the most widely. [0003] Please refer to FIG. 1, which is a driving schematic diagram of dot inversion driving of a liquid crystal display device in the prior art. When the liquid crystal display device displays the nth frame (Frame), the positive and negative polarities of the driving voltage of each pixel (Pixel) and the four adjacent pixels are different. When the liquid c...
