Abstract

A source driver is proposed. The source driver includes N output buffers, (N−1) switches, a first auxiliary switch, a second auxiliary switch, and a third auxiliary switch. The (N−1) switches are respectively coupled between N output terminals of the N output buffers. The first auxiliary switch is coupled between a first output terminal among the N output terminals of the N output buffers and a first endpoint. The second auxiliary switch is coupled between the first output terminal and a second endpoint. The third auxiliary switch is coupled between the first output terminal and a third endpoint. Each of the first endpoint, the second endpoint, and the third endpoint receives a first fixed voltage, a second fixed voltage, a third fixed voltage, or is in a floating state.
