| 摘要 |
The present invention provides a liquid crystal display with a plurality of pixel units. Each pixel unit includes two sub-pixels. Each sub-pixel includes a thin film transistor, a liquid crystal capacitor and a storage capacitor. One of the storage capacitors is a changeable capacitor. By the changeable capacitor, two different data voltages are generated in respective sub-pixels during adjacent frames. The different data voltages are symmetrical with respect to a common voltage to improve image quality.
