Direct Patterning of OLED RGB Color Emitter Layers for High-Brightness High-Resolution Microdisplays
Current methods to produce color emitter layers use a metal shadow mask which suffers from resolution issues and therefore prevents color emitter sub-pixel sizes under 10 microns. Consequently, high resolution OLED microdisplay RGB sub-pixels are typically formed by using white OLED with an overlaying color filter to produce the RBG sub-pixels. The...

The Rochester Digital Cloak
A digital optical cloak to hide an object from multiple viewpoints by digitally recreating a three-dimensional version of the background. Problem Solved by this Technology Whether hiding an object, or removing an inconvenient obstruction from one’s line-of-sight, practical invisibility has remained elusive. While the Rochester Cloak offers a...
