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′ < 0.020 for more than 99.0% of the pixels per frame) can be achieved for 74.2% of the frames using 9216 backlight segments.
