Abstract
An inorganic-light-emitter display includes a display substrate and a plurality of spatially separated inorganic light emitters distributed on the display substrate in a light-emitter layer. A light-absorbing layer located on the display substrate in the light-emitter layer is in contact with the inorganic light emitters. Among other things, the disclosed technology provides improved angular image quality by avoiding parallax between the light emitters and the light-absorbing material, increased light-output efficiency by removing the light-absorbing material from the optical path, improved contrast by increasing the light-absorbing area of the display substrate, and a reduced manufacturing cost in a mechanically and environmentally robust structure using micro transfer printing.
