摘要:
A liquid crystal display (LCD) device and a driving method thereof are provided. The LCD device includes a display panel including pixel units, a data driving circuit, and a gate driving circuit. The gate driving circuit provides a first gate off voltage to one pixel unit of the pixel units when the data driving circuit provides a data voltage having a positive polarity to the pixel unit, the gate driving circuit provides a second gate off voltage to one pixel unit of the pixel units when the data driving circuit provides a data voltage having a negative polarity to the pixel unit. The second gate off voltage is less than the first gate off voltage.

An exemplary burning system (600) for a liquid crystal display (670) includes an optic-electric transformer (610), a comparator circuit (650), and a micro-controller unit (660). The optic-electric transformer is configured for measuring optical flicker of a liquid crystal display, and transforming the measurement into a corresponding flicker signal. The comparator circuit is configured for receiving the flicker signal, comparing a voltage of the flicker signal to a reference voltage, determining whether optical flicker of the liquid crystal display is acceptable or nonexistent based on the comparison, and determining a parameter representing an optimum common voltage of the liquid crystal display when the optical flicker of the liquid crystal display is acceptable or nonexistent. The micro-controller unit is configured for burning the parameter into the liquid crystal display. A related method for burning a liquid crystal display is also provided.
