24.2 Direct View Active Matrix VGA OLED‐on‐Crystalline‐Silicon Display

This paper describes the pixel and array circuitry, which includes a CMOS SRAM cell and a precision current source at each pixel, of a direct view VGA active matrix OLED-on-crystalline-silicon display, developed jointly by IBM Research Division and eMagin Corporation. The display has applications for low-power personal information appliances such as a computer wristwatch. The display obtains data and control signals directly from the memory bus of the appliance's processor.
