COLOUR DISPLAY DEVICE

摘要

A field sequential colour display device has a light source arrangement (16) for providing at least two outputs (R, G, B) in sequence of different colour spectrum. The light source output intensity is controlled independently for each output; in dependence on analysis of the data for an image to be displayed. The brightness of each backlight colour output is thus adapted as a function of the image content, and this enables power savings to be obtained.
