Patent ID: 7804318

Claim:
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 comprising: a reference voltage generator configured for generating a reference voltage; and a voltage comparator configured for receiving the flicker signal, comparing a voltage of the flicker signal to the reference voltage, and generating a result signal based on the comparison; and a micro-controller unit configured for adjusting a common voltage provided to the liquid crystal display in order to reduce or eliminate the optical flicker of the liquid crystal display, if the result signal indicates the optical flicker is in excess of a predetermined threshold, and configured for burning a parameter of the common voltage provided to the liquid crystal display into the liquid crystal display, if the result signal indicates the optical flicker is within the predetermined threshold or does not exist.
