Patent ID: 8212762

Claim:
An output amplifier of a source driver driving a pixel circuit of a panel, the output amplifier comprising: an amplifier circuit comprising an inverting terminal for providing a inverted signal, and a non-inverting terminal for providing a non-inverted signal, wherein the amplifier circuit amplifies an input pixel signal to generate the inverted signal and the non-inverted signal; an output stage circuit comprising a first output terminal for passing a supply voltage or a ground voltage to the pixel circuit according to the inverted signal and the non-inverted signal; a driving stage circuit comprising a second output terminal to drive the pixel circuit, wherein the driving stage circuit passes the supply voltage or the ground voltage to the pixel circuit; a first unity gain buffer, electrically connected to the driving stage circuit, for enhancing and passing the inverted signal from the amplifier circuit to the driving stage circuit; and a second unity gain buffer, electrically connected to the driving stage circuit, for passing and enhancing the non-inverted signal from the amplifier circuit to the driving stage circuit.
