Liquid crystal display device capable of reducing power consumption by charge sharing

摘要

An LCD device includes a plurality of data lines, a plurality of gate lines, a plurality of display units, two dummy gate lines, and a plurality of dummy switches. When performing charge sharing during a positive driving period, the data lines are coupled to a positive voltage source via a corresponding dummy gate line and corresponding dummy switches. When performing charge sharing during a negative driving period, the data lines are coupled to a negative voltage source via a corresponding dummy gate line and corresponding dummy switches.
