Method to improve color reproduction on a 120-Hz two-field color-sequential LCD

Conventional displays use at least three primaries for full‐color image reproduction. In this contribution, the reproduction of color images using an LCD system with two local dynamic primaries, based on a segmented backlight, will be discussed. The two primaries are chosen to minimize color error b...

Description
Summary:Conventional displays use at least three primaries for full‐color image reproduction. In this contribution, the reproduction of color images using an LCD system with two local dynamic primaries, based on a segmented backlight, will be discussed. The two primaries are chosen to minimize color error by means of total least squares. Simulation results indicate quite good color reproduction for a large set of video data even with a limited number of backlight segments. A statistical analysis of this video content shows that excellent color reproduction (∆u′v′
