E-ink displays with an illuminating substance between surfaces of the display screen

摘要

An electronic ink display of a device has a set of charged pigment particles suspended within a fluid. The charged pigment particles and the fluid are positioned between a first surface and a second surface of the display. An electrical charge is able to be applied that causes the charged pigment particles to move within the fluid. Movement of the charged particles results in the charged pigment particles being rearranged to form text or images viewable through the first surface. A luminescent substance is positioned between the first surface and the second surface. When activated, the luminescent substance emits visible light that is transmitted through the first surface.
