Liquid crystal display device having look up table for adjusting common voltages and driving method thereof
A liquid crystal display (LCD) device includes an LCD panel, and a common voltage generating circuit configured for providing common voltages to the LCD panel. The common voltage generating circuit includes a microprocessor, a timer, a voltage adjustment circuit, and a look up table. The microprocessor is electrically connected to the timer, the look up table, and the voltage adjustment circuit. The timer is configured for recording a continuous operated time of the LCD panel. The look up table is configured for storing optimal common voltages corresponding to each continuous operated time. The microprocessor is configured for reading the optimal common voltage at set intervals corresponding to the continuous operated time, and controlling the voltage adjustment circuit to provide the corresponding optimal common voltage to the LCD panel.
