A driving circuit panel and a driving method of a liquid crystal display

The present invention discloses a liquid crystal display driving circuit and a driving method for a panel, the driving circuit comprising: a timing control chip, for receiving the video signal, frame and parsing on signal and need to obtain gray scale display column corresponding to the data voltage signal; and means for calculating the column voltage signal to the data obtained in real time currently required to display sub-pixel units precharge time, and thus obtain a precharge control signal based on the pre-charge time based; scan driving circuit, for receiving the frame to generate a line-on signal scan driving voltage signal; and means for receiving the precharge control signal, and superimposing the driving voltage of the scanning signal, and then converted into voltage line scanning driver, and sent to the corresponding scanning line. Compared with the prior art, the present invention can be calculated in real time currently required precharge time display sub-pixel unit, so as to realize a liquid crystal panel driving power consumption reduction, reducing the temperature of the drive circuit, while improving the sharpness of the display screen.
