Abstract
A liquid crystal display (LCD) is disclosed. The LCD has improved display quality and/or power consumption because current leakage in the pixels is effectively reduced.
Claims22
A liquid crystal display (LCD), comprising:
- a liquid crystal panel including a plurality of pixels configured to be driven during a scan period with data signals, wherein during a sustain period the pixels are configured to emit light according to the data signals;
- a data driver configured to apply the data signals to the plurality of pixels;
- and
- a scan driver configured to apply scan signals controlling the input of the data signals,
- wherein the pixels are configured to receive a common voltage during the sustain period, and wherein the data driver is configured to apply the data signals during the scan period, and to apply a voltage opposite the common voltage to the plurality of pixels during the sustain period.
