Abstract
A circuit for resetting a display having at least one driver outputting a driving voltage through an output channel to a corresponding data line of a panel comprises a first switch and a second switch. The first switch is actuated by a control pulse to transfer a reset voltage to the data line of the panel. The second switch is actuated by the control pulse to electrically isolate the output channel of the driver from the data line of the panel, wherein the control pulse is asserted during transient periods resulting from power-on and power-off of the display.
