To achieve completely consistent LCD panel‐to‐panel color performance in mass production, novel algorithms have been developed for automated tuning and programming of LCD gamma. Optimal gamma is derived using a digital gamma buffer (DGB) and a linear scan method (LSM) as a simple but accurate solution. Another approach uses a V‐T curve interpolation method to achieve shorter tact time.
