Patent ID: 8237645

Claim:
An apparatus for driving a panel in a display system, the apparatus comprising: a reset device for asserting a control signal when the display system is powered off; a gate driver having an input terminal for receiving the control signal and turning on all rows of pixels on the panel when the control signal is asserted; and a pull-high circuit comprising: a resistor having a first end coupled to the input terminal; and a switch having a turned-on state in which the switch couples a second end of the resistor to a supply voltage when the display system is powered on, and a turned-off state in which the switch decouples the second end of the resistor from the supply voltage when the display system is powered off, wherein the switch is a transistor having a gate connected to a ground voltage, a first source/drain connected to the supply voltage, and a second source/drain connected to the second end of the resistor.
