Development of Advanced Technology for 2000 LPI Head-Mounted Displays

Abstract

Operational 2560x2048 active matrix liquid crystal displays (AMLCD) and operational 1280x1024 active matrix electroluminescent displays (AMEL) were demonstrated. Manufacturing technologies were developed for high resolution active matrix displays made in both electroluminescent and liquid crystal formats, extending the state-of-the-art from 1280x1024 pixel (1000 lines/in) to 2560 x 2048 pixel (2000 lines/in) displays. The 2560x2048 displays have 12 microns pixel pitch and a 1.5 in. screen diagonal. On-board circuits, which include video decode, row and column scanners and the pixel TFT's, contain over 5,000,000 transistors-the equivalent of a large scale integrated circuit. The program provided breakthrough display technologies, which are now used in both AMEL and AMLCD display manufacturing processes. 2000 LPI displays for Head-Mounted Display applications are in development.
