DISPLAY WITH LIGHT CONCENTRATING SUBSTRATE
First Claim
1. A display, comprising:
- an array of pixels, each pixel including;
a hydrophobic layer;
an electro-wetting fluid adjacent the hydrophobic layer, the electro-wetting fluid comprising at least first and second fluids immiscible with each other and having different polar properties and different optical properties; and
at least one electrode wherein application of a voltage to the electrode alters a wetting effect of the electro-wetting fluid on the hydrophobic layer in a light-modulating area of the pixel; and
a light-concentrating substrate comprising an array of light-concentrating structures each configured to concentrate light onto the light-modulating area of a corresponding one or more pixels within the array of pixels.

Abstract
A display which includes an array of pixels. Each pixel includes a hydrophobic layer; an electro-wetting fluid adjacent the hydrophobic layer, the electro-wetting fluid including at least first and second fluids immiscible with each other and having different polar properties and different optical properties; and at least one electrode wherein application of a voltage to the electrode alters a wetting effect of the electro-wetting fluid on the hydrophobic layer in a light-modulating area of the pixel. The display further includes a light-concentrating substrate including an array of light-concentrating structures each configured to concentrate light onto the light-modulating area of a corresponding one or more pixels within the array of pixels.
