HIGH DYNAMIC CONTRAST DISPLAY SYSTEM HAVING MULTIPLE SEGMENTED BACKLIGHT

摘要

In one embodiment, a display system includes a subpixelated display panel and a backlight array of individually controllable multicolor light emitters. When the display panel (160) comprises a multi-primary subpixel arrangement having a white (clear) subpixel, the backlight control (130) techniques allows the white subpixel to function as a saturated primary display color. In another embodiment, the display system may calculate a set of virtual primaries for a given image and process the image using a novel field sequential control employing the virtual primaries. In another embodiment, a display system comprises a segmented backlight comprising: a plurality of N + M light guides, said light guides forming a N x M intersections; a plurality of N + M individually addressable light emitter units, each of said N + M light emitter unit being associated with and optically connected to one of said N + M light guide respectively.
