The invention discloses a pixel driving system, which comprises a plurality of first pixel electrode groups and a plurality of second pixel electrode groups in sequential and alternate arrangement in the same direction, wherein the first pixel electrode groups comprise even number of first data wires; each of the first data wires is connected between one row of pixel electrodes and a data driving circuit; the second pixel electrode groups comprise even number of second data wires; each of the second data wires is connected between one row of pixel electrodes and the data driving circuit; in the same frame of image, the data driving circuit exerts bias voltage with different polarities on each pixel electrode of the first pixel electrode groups and each pixel electrode of the second pixel electrodes. The bias voltage exerted on the pixel electrodes cannot influence the public voltage; the voltage difference of the dark state display pixel voltage and the public voltage is stable and unchanged; the dark state display pixel electrodes normally display the dark state effect; the phenomenon of white image of the display is avoided.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a pixel driving system, a liquid crystal display and a pixel driving method. Background technique [0002] Thin Film Transistor-LCD (Thin Film Transistor-LCD, TFT-LCD) has been developed rapidly and widely used in recent years. It is widely used in display devices of portable mobile electronic products, such as mobile phones, digital cameras, handheld computers, GPRS, etc. mobile products. A liquid crystal display panel is generally formed by pairing a color filter substrate and an array substrate, and a liquid crystal layer is encapsulated in the space between the two substrates. The array substrate mainly includes scanning lines, data lines and pixel electrodes. The scanning lines and the data lines are arranged perpendicular to the direction. The pixel electrodes are formed in the pixel area where the scanning lines and data lines are interlaced. The sent signal is sent to ...
