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.

主权项

1. A device comprising:
an electronic ink display having a plurality of charged pigment particles suspended within a fluid, wherein the charged pigment particles and the fluid are positioned between a first surface and a second surface, wherein the first surface is transparent, wherein an electrical charge is applied causing the charged pigment particles to move within the fluid in accordance with the applied electrical charge, wherein movement of the charged pigment particles results in the charged pigment particles being rearranged to form text or images viewable through the transparent first surface, wherein the electronic ink display holds static text and images without using electricity as the applied electrical charge is used to rearrange the charged pigment particles, wherein once arranged that charged pigment particles remain in a relatively static position between the first surface and the second surface without additional consumption of electricity; a luminescent substance positioned between the first surface and the second surface, wherein the luminescent substance when activated emits visible light that is transmitted through the first surface; and a power source that generates energy for the applied electrical charge causing the charged pigment particles to move within the fluid, wherein the power source also generates energy to activate the luminescent substance to cause the luminescent substance to emit the visible light that is transmitted through the first surface wherein the charged pigment particles are round particles that rotate within the fluid responsive to the electrical charge being applied, wherein a portion of the charged pigment particles comprise a first pigment and a different portion of the charged pigment particles comprise a second pigment, wherein rotation of the charged pigment particles responsive to the electrical charge being applied results in the first pigment being seen through the transparent first surface, wherein an opposite rotation of the charged pigment particles responsive to a different electrical charge results in the second pigment being seen through the transparent first surface.
