Liquid crystal display comprising pixel with charge sharing unit and display driving method thereof

摘要

A liquid crystal display includes a date line for transmitting a data signal, a first gate line for transmitting a first gate signal, a second gate line for transmitting a second gate signal, a first sub-pixel unit for being written to by a first sub-pixel voltage according to the data signal and the first gate signal, a second sub-pixel unit for being written to by a second sub-pixel voltage according to the data signal and the first gate signal, a third sub-pixel unit for being written to by a third sub-pixel voltage according to the data signal and the first gate signal, and a charge sharing control unit. The charge sharing control unit is utilized for controlling a charge sharing operation over the first and third sub-pixel units according to the second gate signal, thereby adjusting the first and third sub-pixel voltages.
