Abstract:
An active display can have an increased color gamut and include a group of LED packets that each form a sub-pixel and that together form a pixel for the display. Each LED packet includes at least a red primary color LED, a greed primary color LED, and a blue primary color LED. Each LED can be associated with an intensity value to control the intensity of primary light outputted by the LED. The group of LED packets can output light in a color gamut of a color space for the active display. Each LED packet of the group of LED packets, individually, is configured to output light in the color gamut of a subset of the color space. The active display can display a visual media presentation to an audience. An increased fraction of LEDs from a production batch can be used in the active display.
