Transparent Luminescent Displays Enabled by Electric-Field-Induced Quenching of Photoluminescent Pixels

This technology introduces a light-emitting device that can be controlled to produce light in two distinct states: an "ON" state, where the emitter layer generates light through photoluminescence when illuminated by a light source without an electric field, and an "OFF" state, where the electric field or induced current resulting from a light source and a static or time-varying electric field quenches the emitter photoluminescence. The device includes a photoluminescent pixel and features transparent electrodes and barrier layers. This innovation provides a versatile method for generating light with applications in solid-state lighting, lasers, and more.
