Abstract
Provided are a method of driving a liquid crystal panel which prevents unintended digital image data from being displayed on a liquid crystal panel when power is provided or interrupted, and a source driver and a liquid crystal display apparatus. The source driver includes output buffers; output pads; and a switching unit which is disposed between the output buffers and the output pads and controls an electrical connection state of the output pads. If a level up or a level down of a power voltage occurs, the switching unit prevents output signals of the output buffers from being transmitted to the liquid crystal panel via corresponding output pads and performs at least one of a charge sharing operation for connecting the output pads to each other and a discharging operation for providing a discharge path from the output pads to a ground terminal, in a preset period.
