Abstract:
1. A display using a photoluminescence quenching device, comprising: a substrate with a plurality of sub-pixels arranged on at least a first side of the substrate, wherein a sub-pixel comprises: a first electrode having a first polarity, a second electrode having a second polarity, and an emitter layer, wherein the emitter layer is interposed between the first electrode and the second electrode; an excitation light source for projecting light to the emitter layer; a photoluminescence light emitted from the emitter layer; an electrical field formed between the first electrode and the second electrode which controllably quenches the photoluminescence light from the emitter layer; and a dielectric mirror, wherein light emitted from the excitation light source passes through the dielectric mirror, and the dielectric mirror reflects light emitted from the emitter layer toward an exterior of the display.
