Abstract
A driver device for providing multi-resolution modes for a display device, a liquid crystal display panel for example, is provided in this invention. This display driver includes a pixel circuit and a gate driving circuit. The gate driving circuit is coupled to the pixel circuit via a plurality of gate lines and determines either an original gate driving signal or a target gate driving signal to be the gate drive signal in response to the gate control signal. Wherein a switch circuit is configured for switching between the original driving signal and the target gate driving signal via a plurality of switches corresponding to shift registers therein. A source driving circuit is further incorporated in this present invention to configure a multi-resolution display device, coupled to the pixel circuit via a plurality of source lines and outputs the source driving signal in response to a source control signal.
