A method and apparatus of reducing flicker in liquid crystal displays. A light beam modulated by image information organized by frames is produced. In alternating frames, designed as even and odd frames, the light beam is modulated use complementary voltages relative to a common electrode. The difference in the average modulation in the even frames and in the odd frames over time is determined. That difference is used to adjust the potential of the common electrode such that the difference in the average modulation over time becomes zero.
