Burning system having optic-electric transformer and comparator circuit and method for burning liquid crystal display

摘要

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.
