Abstract
A source driver includes an output buffer, a first switch, a second switch, a third switch, a first transistor, and a second transistor. The output buffer includes a first terminal for outputting a plurality of drive voltage to drive a display panel, a second terminal for outputting a first control signal, and a third terminal for outputting a second control signal. The first switch is connected between the first terminal and a display panel. The first transistor includes a first electrode connected to the second terminal via the second switch, a second electrode connected to a first power supply, and a third electrode connected between the first switch and the display panel. The second transistor includes a fourth electrode connected to the third terminal via the third switch, a fifth electrode connected to a second power supply, and a sixth electrode connected to the third electrode of the first transistor.
