Abstract

A liquid crystal display device capable of being grounded to avoid afterimages includes a liquid crystal panel, a time controller, a gate driver, a data driver, a common voltage generating circuit, and a discharging circuit. The liquid crystal panel includes a plurality of pixel electrodes and a plurality of common electrodes. The pixel electrodes and common electrodes cooperate with each other to form a liquid crystal capacitor. In a power off process, the discharging circuit of the display controls the gate driver to stop generating grayscale voltages and grounds the common voltage generating circuit to discharge the liquid crystal capacitor.
