Abstract

The invention provides a liquid crystal display (LCD) driving mode. The LCD comprises a plurality of pixel units, each pixel unit comprises three sub-pixels, and is characterized in that in one charging process, any two sub-pixels are charged at first, then the third sub-pixel is charged; in the next charging process, the third sub-pixel is charged at first; in the one charging process, the charging times of the two sub-pixels that are charged at first are equal and longer than that of the third sub-pixel, and one complete charging process means that all three sub-pixels are all charged. On the basis that the resolution is increased and the refresh rate is not changed, the LCD can guarantee the sufficient charging of sub-pixels, thus avoids the color difference, and improves the quality of display frame.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a liquid crystal display and its driving method. Background technique [0002] With the continuous development of liquid crystal display technology, liquid crystal display (Liquid Crystal Display, LCD), which has the advantages of small size, low power consumption, and no radiation, has gradually replaced cathode ray tube (Cathode Ray Tube, CRT) display as the display device. Mainstream products are gradually and widely used in various electronic products. [0003] In the prior art, the pixel driving structure of traditional TFT (Thin Film Transistor, Thin Film Field Effect Transistor) LCD generally includes data line (Data Line, also called Source Line), scan line (Gate Line, also called gate line) , wherein the data lines are vertically arranged in columns and parallel to each other, the scanning lines are horizontally arranged in rows and parallel to each other, and the...
