Patent ID: 8207929

Claim:
A source driver, adapted to drive a plurality of data lines on a display panel, wherein the data lines include a plurality of odd data lines and a plurality of even data lines alternatively arranged, comprising: a first output buffer, having a first input terminal receiving a first pixel signal, and both of a second input terminal and an output terminal coupled together, for enhancing the transmission intensity of the first pixel signal; a second output buffer, having a first input terminal receiving a second pixel signal, and both of a second input terminal and an output terminal coupled together, for enhancing the transmission intensity of the second pixel signal; a multiplexer, having a first input terminal coupled to the output terminal of the first output buffer, a second input terminal coupled to the output terminal of the second output buffer, a first output terminal coupled to one of the odd data lines and a second output terminal coupled to one of the even data lines, wherein the multiplexer transmits the first pixel signal and the second pixel signal to the one of the odd data lines and the one of the even data lines respectively, or to the one of the even data lines and the one of the odd data lines respectively according to a control signal; and a first regulating unit, coupled between the output terminal of the first output buffer and the first input terminal of the multiplexer for regulating a first slew rate of the first pixel signal outputted from the first output buffer to match a second slew rate of the second pixel signal outputted from the second output buffer, and transmitting the first pixel signal to the multiplexer.
