Single-layer reflective display utilizing luminescence

摘要

A reflective display device has multiple display pixels. Each pixel has at least three color sub-pixels disposed side-by-side for three primary colors respectively. At least one color sub-pixel has a light shutter with adjustable transmission, a luminescent layer containing a luminescent material that emits light of a selected color, and a mirror for reflecting light corresponding to that selected color.

主权项

1. A reflective display pixel comprising:
at least three sub-pixels disposed side-by-side, each of the sub-pixels corresponding to one of three primary colors, at least one of the sub-pixels having:
a light shutter with adjustable transmission;a luminescent layer disposed below the light shutter and containing a luminescent material that emits light of a selected primary color when illuminated by light received from the light shutter; anda mirror disposed below the luminescent layer to reflect light corresponding to the selected primary color emitted by the luminescent layer, the light being reflected in a direction toward the light shutter to pass through the luminescent layer, wherein the luminescent layer is sandwiched between the light shutter and the mirror.
