eMagin Wins Patent for TFT OLED Device

Provides path to ultra-high resolution, large and small TFT OLED displays

HOPEWELL JUNCTION, N.Y., October 21, 2004 -- eMagin Corporation (AMEX:EMA) has received notification of allowance from the U.S. Patent and Trademark Office regarding patent issuance for the invention of U.S. Patent application No. 09/957,221, "Method and system for stabilizing thin film transistors in active matrix OLED displays.”

This patent describes a method of creating electrically stable TFTs (thin film transistors) for OLED devices having small pixel sizes, which facilitates creation of lower cost microdisplays for many virtual imaging applications including electronic gaming, data processing, and viewing movies. The approach is also potentially useful for creating very high resolution large screen OLED displays.

In this invention, the control signals to each TFT gate include a data signal that is proportional to the desired luminance output for the OLED and a reverse data signal that is used to reverse bias the TFT to prevent threshold drift in the TFT. The data signal alteration is performed either at a frame rate or at a line rate. The result is a large color range and more stable control than previously available using TFTs.

“This new invention provides an opportunity to not only create ultra high performance microdisplays on single crystal silicon ICs, but to also create a lower cost alternative for many customers desiring large virtual images at a very low cost,” said Susan Jones, eMagin's chief marketing and strategy officer. “We also look forward to working with partners interested in using this innovative technology to create low-cost, large-area OLED displays.”

The global market for OLEDs is forecast to grow from a projected $429 million this year to $4 billion in 2008, according to market research firm iSuppli Corp.
