In the dynamic gamut display systems, video input data is processed to extract metrics indicative of the gamut occupancy of the frame pixels. The extracted metrics are used to form a set of scale factors to be used by the display to synthesize an adapted gamut that matches the frame pixel color gamut from the native color primaries of the display. The generated gamut adaptation scale factors are used to convert the frame pixels' values to the adapted gamut which are provided to the display for modulation using the synthesized adapted gamut for each video frame or a sub-region of a video frame. The methods enable increased display brightness, reduced power consumption and reduced interface and processing bandwidth. Also disclosed is an adapted video frame data formatting method that maps the benefits of the adapted gamut into a reduced frame data size enabling bandwidth savings when used for video distribution.

Dynamic gamut display systems, methods, and applications thereof

Emissive quantum photonic imagers comprised of a spatial array of digitally addressable multicolor pixels. Each pixel is a vertical stack of multiple semiconductor laser diodes, each of which can generate laser light of a different color. Within each multicolor pixel, the light generated from the stack of diodes is emitted perpendicular to the plane of the imager device via a plurality of vertical waveguides that are coupled to the optical confinement regions of each of the multiple laser diodes comprising the imager device. Each of the laser diodes comprising a single pixel is individually addressable, enabling each pixel to simultaneously emit any combination of the colors associated with the laser diodes at any required on/off duty cycle for each color. Each individual multicolor pixel can simultaneously emit the required colors and brightness values by controlling the on/off duty cycles of their respective laser diodes.
