Microdisplays based upon organic light-emitting diodes

Microdisplays, some of which exploit the dense electronic circuitry in a silicon chip, are enabling a new wave of ultraportable information products, including headsets for viewing movies and cell phones with full-screen Internet access. This paper reports the approach to microdisplay development at eMagin Corporation. The requirements for microdisplays are reviewed, and the case is made that organic light-emitting diodes (OLEDs) are the best candidate transducer technology for meeting these requirements. A 1280 × 1024 (SXGA) monochrome OLED microdisplay is described as an example.
