Abstract
A source driver adapted to drive a plurality of data lines on a display panel is disclosed. The source driver includes a first output buffer, a second output buffer, a multiplexer, and a first regulating unit. The first and the second output buffers respectively enhance transmission intensities of a first and a second pixel signals. The first regulating unit regulates a slew rate of the first pixel signal outputted from the first output buffer to match a slew rate of the second pixel signal outputted from the second output buffer. The multiplexer coupled to the regulating unit selectively transmits the first and the second pixel signals to one of the odd data lines and one of the even data line, or to the one of the even data lines or the one of the odd data lines, according to a control signal.
