Abstract: A plasma display panel (PDP) driving apparatus and a method for displaying pictures on the PDP increases the ability to express low gray scales without increasing the number of sub-fields. Input picture signal data are delayed by one frame and the number of high-order bits, from most significant bits not commonly used by all picture signal data within one frame, is detected. When the number of unused bits is detected, inverse gamma-corrected decimal point bits are shifted to an actual data position by the number of unused bits so as to increase power of expression of low gray scale. The decimal point bits are converted into sub-fields having low gray scale weights, in consideration of the shifting to the actual data position, for display on the PDP.

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.
