Abstract
A surface display unit incorporates an opaque screen and an image panel. 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.
