Abstract

In one embodiment, a hybrid display that may include a first light emitter of a first type and a second light emitter of a second type that define first and second addressable subpixels of a hybrid pixel. The first and second light emitters may be coupled to a support and provided with drive means for emitting light. The hybrid subpixels may be arranged in a variety of formats to provide a desired emission of light from the hybrid pixel. The support may be flexible to provide a flexible hybrid display. A dummy subpixel may be provided for spacing or to allow for transmission of light from another light emitter and light guides may be provided for guiding light to the dummy subpixel.
