Abstract
There is provided a source driver capable of controlling the timing of source line driving signals in a liquid crystal display device. The source driver includes a plurality of output circuits, each output circuit including an output buffer and a switch. The output buffer amplifies an analog image signal, and the switch outputs the amplified analog image signal as a source line driving signal in response to a control signal. The source driver further comprises a control circuit for generating the control signal, the control circuit comprising: a delay circuit delaying a switch signal and generating a delayed switch signal; and a multiplexer selecting one of the switch signal and the delayed switch signal in response to a selection signal and outputting the selected signal as the control signal.
