Abstract

See full text

Disclosed herein are various embodiments related to luminescence-based reflective display pixels. In one embodiment, among others, a luminescent-based pixel includes a luminescent layer including luminophores distributed in a matrix. The luminescent layer is configured to receive light from an ambient environment through a first side of the luminescent layer and has an index of refraction that is higher than an index of refraction of the ambient environment. The luminescent-based pixel includes a mirror disposed on a second side of the luminescent layer that is opposite the first side of the luminescent layer. The luminescent-based pixel also includes a diffusive surface to randomize the direction of incident light.
