Source driver having multiplexers positioned between differential amplifiers and buffers and associated driving method

摘要

A source driver includes a first differential amplifier, a first output stage, a second differential amplifier, a second output stage and a multiplexer. The first differential amplifier is utilized for receiving a first differential input signal pair to generate a first differential output signal pair. The second differential amplifier is utilized for receiving a second differential input signal pair to generate a second differential output signal pair. The multiplexer couples the first differential amplifier to the first output stage and couples the second differential amplifier to the second output stage under a first configuration, and couples the first differential amplifier to the second output stage and couples the second differential amplifier to the first output stage under a second configuration.
