Patent ID: 8537153

Claim:
A source driver, comprising: a first channel, comprising: a first differential amplifier, for receiving a first differential input signal pair to generate a first differential output signal pair; a first output stage; and a first control circuit, coupled to the first output stage, for selectively disabling the first output stage to make the first output stage not output data to a pixel array; a second channel, comprising: a second differential amplifier, for receiving a second differential input signal pair to generate a second differential output signal pair; a second output stage; and a second control circuit, coupled to the second output stage, for selectively disabling the second output stage to make the second output stage not output data to the pixel array; and a multiplexer, having a first input port coupled to the first differential amplifier for receiving the first differential output signal pair, a second input port coupled to the second differential amplifier for receiving the second differential output signal pair, a first output port coupled to the first output stage, and a second output port coupled to the second output stage, wherein the multiplexer couples the first input port to the first output port and couples the second input port to the second output port under a first configuration, and couples the first input port to the second output port and couples the second input port to the first output port under a second configuration.
