ABSTRACT:
A liquid-crystal display device performs a feedback process. A video signal is written on pixels on a unit by unit basis, each unit including a plurality of pixels (six pixels, for example). Scan pulses output from RGB LCD panels are supplied to a driver IC that supplies the RGB LCD panels with a variety of timing signals. A delay amount from the scan pulses from the optimum state thereof is measured. The delay amount is accounted for in a pulse that samples and holds the video signal, i.e., a pulsewidth control clock pulse.
