Abstract
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.
