摘要：In one embodiment, a display system includes a subpixelated display panel and a backlight array of individually controllable multi-color light emitters. When the display panel comprises a multi-primary subpixel arrangement having a white (clear) subpixel, the backlight control 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 NxM 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.
