Transparent, Conformable Miniature Displays

"This proposal describes a novel approach, integrating high performance transistors for active matrix addressing with organic light-emitting diode (OLED) technology, to fabricate transparent and conformable miniature displays. Using standard low-powercomplementary metal-oxide-semiconductor (CMOS) processing, we propose to utilize high-mobility silicon thin films to realize high-speed driver electronics. This coupled with the growth of long-lived Alq3-based OLED structures on insulating substrates,provides a viable methodology in realizing transparent miniature displays. Additional features include: radiation hardening properties, higher mobility in strained Si layers, and the ability to integrate other sensors and image processing modules in amonolithic processing needed to develop night vision goggles (NVGs) for defense and consumer applications. In Phase-I, a prototype active matrix addressed micro-array consisting of 4 x 4 pixels and driver electronics will be fabricated using MOSIS foundryaccording to our initial test chip design. Subsequently, monochrome OLED structures with brightness exceeding 100 cd/m2 will be grown and characterized. In Phase-II, a prototype chip (1" diagonal) consisting an array of 320x240 monochrome pixelsintegrated with addressing CMOS circuitry will be constructed using MOSIS foundry. In addition to DOD-directed applications such as helmet mounted displays, night vision goggles, and radiation harden
