Abstract
A liquid crystal display and a driving method thereof are provided. A pixel of the liquid crystal display includes a first pixel capacitor, a second pixel capacitor, a first transistor, and a second transistor. A first terminal and a second terminal of the first pixel capacitor are respectively coupled to the first transistor and a common voltage. A first terminal and a second terminal of the second pixel capacitor are respectively coupled to the second transistor and the common voltage. A voltage between the first and the second terminals of the first capacitor is differentiated from a voltage between the first and the second terminals of the second capacitor by modulating the common voltage. A coupling voltage of the first pixel capacitor is differentiated from a coupling voltage of the second pixel capacitor by modulating the common voltage. Thereby, the phenomenon of color wash-out is reduced.
