Abstract
A flat panel display, a shift register with image retention release and method for releasing image retention are provided. An output end of the shift register couples to a gate line of a display panel. A first end of a first transistor couples to the output end of the shift register. A second end of the first transistor couples to a system voltage VDD or a reference voltage VSS. A first end of a capacitor couples to a control end of the first transistor. A second end of the capacitor couples to the reference voltage VSS. During a power-off period, the reference voltage VSS is pulled high for turning on the first transistor, therefore the voltage of the gate line is pulled high.
