附加通讯装置;ADJUNCT COMMUNICATION DEVICE

摘要

一种附加通讯装置系包括一外罩、一基座、一显示单元，以及一观看萤幕。该显示单元之部分系位于内部之该基座，且该显示单元包括一输出表面，用以输出多个光学讯号，该光学讯号系关于一第一组光学行进途径。该观看萤幕，设置于该外罩内，该观看萤幕包括一观看表面，该观看表面系用以接收该光学讯号，以及至少部分地导引关于一第二组光学行径途径之该光学讯号，其中该第二组光学行径途径定义一观测角。; and a viewing screen mounted within the housing, the viewing screen comprising a viewing surface, the viewing surface configured to receive the optical signals, and further configured to at least partially direct the optical signals relative to a second set of optical travel paths, wherein the second set of optical travel paths defines a viewing angle.
