Abstract
A liquid crystal display device has a liquid crystal panel module, sampling circuits that sample video signals a timing adjustment module driving signal generators and a dummy element. The timing adjustment module detects a variation in signal delay in the driving signal generators with a temperature change or with time, as a phase difference of an output signal from the dummy element relative to a reference signal. The timing adjustment module adjusts the phase of the timing signal corresponding to the detected phase difference. This arrangement corrects a temporal deviation of the sampling circuit driving signals from the video signals, which is caused by the variation in signal delay in the driving signal generators, and thereby effectively restrains the occurrence of ghost.
