Surface display units with opaque screen
First Claim
1. A surface display unit comprising:
- an image panel configured to provide an optical image on a front surface thereof; and
a opaque screen disposed over the front surface of the image panel,wherein the opaque screen comprises an opaque matrix material layer that transmits light, reflects light or transmits and reflects light from the image panel;
wherein the opaque matrix material layer has a transmission coefficient of from 0.01 to 0.5 within the wavelength range from 400 nm to 800 nm for light from the optical image.

Abstract
A surface display unit incorporates an opaque screen (180) and an image panel (110). The opaque screen is disposed on the front side of the image panel which provides an optical image. The opaque screen generally hides the image panel while the surface display unit is not in use. When the image panel is activated to provide an optical image, the opaque screen provides a suitable level of transparency so that a viewer can observe the optical image with sufficient clarity. The opaque screen can provide optical enhancement, decorative texture, and/or mechanical support and include antiglare, anti-reflective, and anti-scratch films (140, 150, 160). The opque screen can be a laminated polymer film, an electrochromic or photochromic system, or a switchable dye doped liquid crystal material.
