Source driver and display device with protection unit

摘要

A source driver for driving a display panel and including a protection unit, a bias voltage generation unit and a buffer is provided. The protection unit detects a characteristic parameter of the source driver, and generates a switching signal according to a detection result. The bias voltage generation unit determines whether or not to provide a bias voltage according to the switching signal. The buffer is operated in the bias voltage so as to drive pixels in the display panel.
