摘要: Field-sequential-color mode has benefits on energy efficiency, because colors are made by flashing the backlight red, green, and blue and the color filters are not needed, leading to increased light transmission. However, field-sequential-color mode causes annoying color breakup. In previous studies, a spatio-temporal display has been proposed as a hybrid solution to balance the increase of light transmission and the suppression of color breakup. However, color breakup remains visible for critical image content. In this paper, a 120-Hz liquid crystal display with two-color filters mounted with a backlight consisting of a light emitting diode matrix is introduced. The backlight colors are locally desatured according to the local image content, so the color difference between fields is reduced, and the perceived color breakup is effectively suppressed. Various examples with different color filter and backlight settings are described and analyzed, aiming at different display-performance objectives.
