LOW COLOR SHIFT MULTI-VIEW DISPLAY DEVICE AND DISPLAY METHOD THEREOF

摘要

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.

主权项

1. A display device comprising:
a display panel including first and second pixel groups, wherein each of the pixel groups includes a color pixel, and the color pixel of the first pixel group and the color pixel of the second pixel group are with the same color; and a data driver, coupling to a number of impedance strings, providing a plurality of voltages according to multiple nodes of the impedance strings, wherein the color pixel of the first pixel group has a first color voltage and the color pixel of the second pixel group has a second color voltage; wherein the first color voltage differs from the second color voltage when a frame signal is configured to display an equal gray level.
