Abstract
An apparatus for driving a panel in a display system includes a reset device, a gate driver and a pull-high circuit. The reset device asserts a control signal when the display system is powered off. The gate driver has an input terminal receiving the control signal and turns on all rows of pixels on the panel when the control signal is asserted. The pull-high circuit includes a resistor and a switch, in which the resistor has a first end coupled to the input terminal, and the switch decouples a second end of the resistor from a first reference voltage when the display system is powered off.
