TRANSPARENT LUMINESCENT DISPLAYS ENABLED BY ELECTRIC-FIELD-INDUCED QUENCHING OF PHOTOLUMINESCENT PIXELS

摘要

A light emitting device can include a light source, a first electrode, a second electrode, a first barrier layer, a second barrier layer, and an emitter layer between the first barrier layer and the second barrier layer. A method of controllably generating light can comprise two states: An ON state, wherein an emitter layer of a device (which includes a photoluminescent pixel) is illuminated with a light source in the absence of an electric field, and the emitter layer generates light through photoluminescence; and an OFF state, wherein an emitter layer of a device (which includes a photoluminescent pixel) is illuminated with a light source in the presence of a static or time-varying electric field, and the electric field or induced current results in quenching of the emitter photoluminescence.
