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

A method for burning a liquid crystal display, the burning method comprising:

• generating a flicker signal according to an amount of optical flicker of a liquid crystal display;
• comparing a voltage of the flicker signal to a reference voltage, and generating a first result signal if the voltage of the flicker signal is less than the reference voltage, the first result signal indicating that a burning procedure can be launched;
• and
• burning a parameter representing an optimum common voltage of the liquid crystal display into the liquid crystal display.

A burning system for a liquid crystal display, the burning system comprising:

• an optic-electric transformer configured for measuring optical flicker of a liquid crystal display, and transforming the measurement into a corresponding flicker signal;
• a comparator circuit 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;
• and
• a micro-controller unit configured for burning the parameter into the liquid crystal display.
