Abstract
A device for tuning an output enable signal and a method thereof are provided. In the method, a first scan signal and a second scan signal are filtered out according to a duty cycle of the output enable signal, so as to provide a first output scan signal and a second output scan signal. The duty cycle of the output enable signal is increased when a voltage level of the second output scan signal is converted from a disable state to an enable state before a voltage level of the first output scan signal is converted from an enable state to a disable state. Thereby, a rewriting problem is avoided.
