INTERACTIVE DISPLAY USING PLANAR RADIATION GUIDE

摘要

An interactive display that uses a planar radiation guide (such as a plan ar light guide) to perform display and/or imaging. The planar radiation guid e has a radiation propagation portion and a radiation interface portion. The radiation propagation portion propagates the radiation by the principles of total internal reflection (with perhaps some minor leakage). The planar rad iation guide also has a radiation interface portion where radiation is more apt to exit or enter the planar radiation guide. The interactive display per forms both display and imaging, while the planar radiation guide is used to perform at least one (but perhaps both) of the display and imaging operation s.
