SURFACE DISPLAY UNITS WITH OPAQUE SCREEN

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. 种表面显示单元，结合了不透明屏幕(180)和图像面板(110)。所述不透明屏幕被布置在提供光学图像的所述图像面板的前侧上。当所述表面显示单元不使用时，所述不透明屏幕般隐藏所述图像面板。当所述图像面板被激活用于提供光学图像时，所述不透明屏幕提供合适的透明度，使得观察者可以以足够的清晰度观察到所述光学图像。所述不透明屏幕可以提供光学增强、装饰性纹理和/或机械支撑并且包括防眩光膜、减反射膜和防刮擦膜(140，150，160)。所述不透明屏幕可以是叠层聚合物膜
