Optical Bonding and Surface Treatments - Planar Expertise in Electronic Design

Terry Trover, Sr. Product Manager for Planar, recently wrote a great article about many of the considerations in using optical bonding and surface treatments. His biggest challenge was summarizing a ton of information into a two-page article for Electronic Design. Here's a brief excerpt from the article.

Typically, most protective windows and touchscreens adhere to TFT displays with double-sided tape, leaving an air gap between the polarizer surface and the overlay. Yet light reflects when it travels between various mediums with differing indexes of refraction. If you place a transparent protective window on top of a display, light willreflect back at the viewer where the interface of air and glass meet. Light will also reflect back when it exits the medium.
