Display device and method that divides one frame period into a plurality of subframe periods and that displays screens of different colors in accordance with the subframe periods
Abstract:
A display device that adopts a field sequential method and that is capable of achieving desired luminance while suppressing mixing of colors is provided. With respect to display of each color by a liquid crystal display device adopting a field sequential method, a period is provided for which light sources of each color remain turned on until a turning-off delay time has elapsed since an end timing of a subframe period. The turning-off delay time relating to LEDs for which an off state begins in a preceding subframe period is configured in such a way as to be shorter than a turning-on delay time relating to LEDs for which an on state begins in a succeeding subframe period. As a result, an all-off period, in which LEDs of all colors are in the off state, is provided between on periods of two colors.
