Touchscreens for displays
First Claim
1. A display comprising:
- a light-modulating array; and
a touchscreen disposed forward of the light-modulating array such that light from the light-modulating array passes through the touchscreen, the touchscreen including diffusing material that diffuses light from the array of interferometric modulators as the light propagates through the touchscreen.

Abstract
In various embodiments of the invention, an interferometric light modulating display device is provided having a touchscreen above the light modulating display device. The touchscreen may have a diffusing material that may be part of the touchscreen. In some embodiments, the diffusing material may be used to reduce or minimize the color-shift or may be used to change the properties of light reflected by the display such that light modulating display device appears more diffuse and less specularly reflecting. In other embodiments, a light source is provided beneath the touchscreen and one or more reflective surfaces are provided such that at least a portion of the light from the light source that is directed toward the touchscreen is reflected to the light modulating device without passing through the touchscreen. In other embodiments, a diffusing material is provided that may scatter light using different sized scatterers.
