Abstract:
1. A source driver of a liquid crystal display device, comprising: a plurality of output circuits; and a plurality of control circuits, wherein each of the output circuits comprises: an output buffer amplifying an analog image signal; and a switch outputting the amplified analog image signal as a source line driving signal in response to a control signal, and wherein each of the control circuits comprises: a plurality of delay circuits, each of the delay circuits delaying a switch signal and generating a delayed switch signal; and a multiplexer selecting the switch signal or one of the delayed switch signals in response to a selection signal and outputting the selected signal as the control signal, wherein each of the delay circuits directly receives the switch signal and holds the switch signal for an amount of time that is different than that of another delay circuit so that the delayed switch signals have different delay times.
