摘要： A display system includes a reflective display panel and a light source tailored to enhance the color gamut of the system. The panel, which may be a Cholesteric liquid crystal display panel, includes an array of reflective pixels, each pixel comprising a first, second, and third subpixel of different first, second, and third colors. The light source illuminates a front of the display panel with source light to enable observers to view images formed by the panel. The light source includes a lamp and an enhancing element. The lamp, which may be a metal halide lamp, emits lamp light that includes the first, second, and third colors. The enhancing element may be an optical filter, a supplemental LED light source or other light source, or both. The enhancing element enhances the system color gamut, for example, by increasing the color gamut area relative to illumination with the lamp alone.

摘要： A direct view display provides a light modulating panel and a backlight including first and second sets of spectral emitters. Several modes of operation may be provided including an advanced 2D mode, and an enhanced color gamut mode employing simultaneous illumination of the first and second set of spectral emitters. Another embodiment may be an optical structure for a multi-functional LCD display with wide color gamut and high stereo contrast. The optical structure may also be used to produce more saturated colors for a wider display color gamut and also may be used to produce a brighter backlight structure through light recycling of the wider bandwidth light back into the optical structure.
