Methods and apparatus for actuating displays
First Claim
1. A display apparatus comprising:
- an array of electrowetting-based light modulators for transmissively displaying an image;
a reflective aperture layer defining a plurality of apertures, for reflecting light not passing through apertures in the reflective aperture layer away from the array, wherein the reflective aperture layer is formed on a first substrate and positioned adjacent the array, and the image is formed by modulating light passing through the apertures in the reflective aperture layer; and
a light guide, separated from the first substrate by a gap, for guiding light towards the reflective aperture layer.

Abstract
This invention relates to display apparatuses having an array of light modulators for transmissively displaying an image and a reflective aperture layer defining a plurality of apertures, for reflecting light not passing through apertures in the reflective aperture layer away from the array. The reflective aperture layer is formed on a first substrate and positioned adjacent the array. The image is formed by modulating light passing through the apertures in the reflective aperture layer. A light guide, separated from the first substrate by a gap, may guide light towards the reflective aperture layer. A layer of low-refractive index material may be positioned on a side of the reflective aperture layer opposite the array.
