Abstract
A method for generating sampling signals for use in an active matrix display is provided. Firstly, a plurality of pulse signals are sequentially generated, wherein every two adjacent pulse signals have a phase difference therebetween. Then, a guarding signal having alternate first level and second level is generated. Then, sampling signals associated with the pulse signals are outputted in response to the guarding signal being at the first level, and any sampling signal is exempted from outputting when the guarding signal is at the second level. A device for generating sampling signals for use in an active matrix display is also provided.
