Patent ID: 10147372

Abstract:
The present disclosure relates to a driving circuit and a driving method of liquid crystal panels. The driving circuit includes a timing control chip receiving video signals and analyzing frame turn-on signals and column data voltage signals corresponding to a needed grayscale, calculating a pre-charge time period needed for the subpixels to be displayed in a real-time manner and obtaining pre-charge control signals in accordance with the pre-charge time period. The driving circuit also includes a scanning driving circuit receiving the frame turn-on signals and generating the row-scanning-driving voltage signals, overlapping the pre-charge control signals and the row-scanning-driving voltage signals to obtain the row-scanning-driving signals, and transforming the row-scanning-driving signals into row-scanning-driving voltage, then transmitting the row-scanning-driving voltage to a corresponding scanning line. In this way, the power consumption and the temperature of the driving circuit are reduced, and the sharpness of the display images is enhanced.
