The technique presented in this paper maximizes LCD color performance by way of advanced gamma control technology. RGB gamma curve control is used to first establish accurate on‐axis color, then two gamma curves corresponding to two sub‐pixels are mixed to minimize gamma distortion off‐axis. Independent RGB curve control for each sub‐pixel improves the LCD's performance both on‐ and off‐axis.
