Patent ID: 8279138

Claim:
A flat panel display comprising: three or more different wavelength light sources including three or more different wavelength LEDs positioned at multiple locations in said display; light source controls to separately vary brightnesses of said light sources within different regions of said display; an image modulator including an array, having a modulator resolution, of individually controllable pixels into which pixel values are scanned during an image modulator scanning time; and one or more controllers for receiving an input data stream containing image data, spatial processing image data for a display frame into three or more image color fields each corresponding to a different wavelength, filtering said image color fields to match said image modulator resolution, and filtering image data to a light source resolution, lower than said image modulator resolution, for controlling said LEDs; wherein each of said image color fields has both a duration and an LED color combination which can be varied by said light source controls switching LEDs for successive color fields.
