Lcd driver circuit and driving method thereof

Abstract

An LCD driver circuit having a common electrode, a gate driving circuit and a source driving circuit is provided. The LCD driver circuit is applied to a display panel which has a plurality of pixels, a plurality of scan lines and a data line. The scan lines are divided into a plurality of scan line groups. The scan line groups are disposed on the display panel in a first sequence. The common electrode outputs a common voltage. The gate driving circuit is coupled to the scan lines and provides a control voltage to each scan line in a second sequence different from the first sequence. The source driving circuit is coupled to the data line to provide a gray level voltage to the data line. An area of the gray level voltage being higher or lower than the common voltage corresponds to a high level area of the control voltages in the nonadjacent scan line groups, and polarities of the operated pixels in the adjacent scan line groups are opposite.
