Multi-color liquid crystal display

Some embodiments of the invention provide a device, system and method for displaying a color image. According to some exemplary embodiments of the invention a device for displaying a color image may include an illumination source including a plurality of light-producing elements able to produce light of each of m different wavelength spectra, wherein m is equal to or greater than three. The device may also include an array of attenuating elements able to spatially selectively attenuate the light produced by the illumination source according to an attenuation pattern corresponding to a gray-level representation of the color image, and an array of color sub-pixel filter elements able to receive selectively attenuated light from the array of attenuating elements, each sub-pixel filter element able to transmit light of one of n different primary colors, wherein n is equal to or greater than four.

Multi-primary display with spectrally adapted back-illumination

A sequential color LCD device for displaying a color image using at least four different primary colors, with back illumination system comprising of at least three color LEDs. The device is capable of activating at least two color LEDs simultaneously, thus obtaining additional display colors. A method is disclosed for displaying more than three colors using an LCD device having three color LEDs, in which the LED back illumination system sequentially illuminates the LC array with only a first single LED color, a simultaneous operation of first and second LED colors, and then only the second LED color. The device may drive the LC cells from a first color data value directly to a subsequent color data value directly, without driving the LC cell to zero transmittance prior to loading of the subsequent color data value. The device may correct for color phase shift and for the dependency of apparent color intensity.
