摘要： An apparatus to widen the light dispersion pattern of a light source shining through an overlay window from the viewing side of an electrical computer system. The overlay window is coupled to a panel of the system. The overlay window includes a transparent material, which has a first surface facing the light source and a second surface facing away from the light source to define a viewing side. An opaque material can be disposed on the first surface to partially cover the first surface to form a viewing window. A first diffusing mechanism is disposed on the first surface, and a second diffusing mechanism is disposed on the second surface. In response to the passage of the light output through the viewing window, the light dispersion pattern of the light output from the viewing side of the overlay window has a viewing angle of up to about 180 degrees.

摘要翻译： 一种通过覆盖窗口从电子计算机系统的观察侧扩展的光源的光散射图案的装置。 覆盖窗口耦合到系统的面板。 覆盖窗口包括透明材料，其具有面向光源的第一表面和背离光源的第二表面以限定观察侧。 不透明材料可以设置在第一表面上以部分地覆盖第一表面以形成观察窗。 第一扩散机构设置在第一表面上，第二扩散机构设置在第二表面上。 响应于通过观察窗口的光输出的通过，从覆盖窗的观看侧输出的光的光散射图案具有高达约180度的视角。
