Low color shift multi-view display device and display method thereof
View Patent ↗According to various embodiments of the invention, gamma curves for multiple pixel groups can be calibrated using look-up tables or by using reference voltage groups provided by gamma voltage generators so that the pixels can display multiple images with correct gray levels at different view angles. Therefore, color shift can be avoided or lessened without necessarily using extra circuitry on the display panel. Also, any related light transmittance or light utilization efficiency reduction may be decreased or eliminated.
