Abstract:
1. A color display device, comprising: an illumination device comprising a plurality of laser light sources or light emitting diode (LED) light sources for generating an illumination light of a plurality of different colors; at least one spatial light modulator modulates said illumination light for forming a display image; and a control device analyzes an input image data for determining a first and second primary colors contained in successive frames necessary for increasing and decreasing levels of gray scale respectively and the control device further includes a data converter for converting at least a portion of the input image data into non-binary data bits and assigning each data bit with an equal weight for controlling said spatial light modulator and said illumination device by applying said input image data with said non-binary data bits assigned with said equal weight and change, according to a set of more flexible non-binary ratios as analyzed by the control device, a light emission intensity of said first and second primary colors of said illumination light emitted from the illumination device to increase and decrease the levels of gray scale of said first and second primary colors respectively.
