Abstract
An output amplifier includes an amplifier circuit, an output stage circuit, a first switch transistor, and a second switch transistor. The amplifier circuit is used for amplifying an input pixel signal to generate the inverted signal and the non-inverted signal. The output stage circuit has a first output terminal for passing a supply voltage from a supply terminal or passing a ground voltage from a ground terminal to the pixel circuit according to the inverted signal and the non-inverted signal. The first switch transistor passes or blocks the supply voltage according to a high impedance signal, and the second switch transistor passes or blocks the ground voltage according to the inverted high impedance signal.
