Abstract

A display system ( 10 ) for digital color images using six color light sources ( 12 ) or two or more multicolor LED arrays ( 212, 213 ) or OLEDs ( 220, 222 ) to provide an expanded color gamut. Apparatus ( 10 ) uses two or more spatial light modulators ( 20, 21 ), which may be cycled between two or more color light sources ( 12 ) or LED arrays ( 212, 213 ) to provide a six-color display output. Pairing of modulated colors using relative luminance helps to minimize flicker effects.

Claims (5)

1. A method for displaying a color image from digital data comprising:

(a) providing image data for at least a first and a second color to a first polymer light emitting diode and emitting said at least said first and said second color from said first polymer light emitting diode as a first multicolor modulated beam;

(b) providing image data for at least a third and a fourth color to a second polymer light emitting diode and emitting said at least said third and said fourth color from said second polymer light emitting diode as a second multicolor modulated beam;

(c) combining said first and said second multicolor modulated beams to form a combined multicolor modulated beam; and

(d) directing said combined multicolor modulated beam to a display surface.
