Abstract
A virtual display with 1120 X 900 pixel resolution has been constructed using a high density LED array and scanning optics. The display has a field of view of 25 degree(s) X 20 degree(s). The display is small, light weight, and suitable for hand-held or head-mounted use. Pixels appear red on a jet black background. Individual pixel size is 1.3 arc minutes, which is near the resolution limit of the human eye. Pixels appear crisp and sharply defined. Contrast ratio is over 500:1. The paper describes operation of the display in detail, and discusses design tradeoffs encountered in the development of high resolution virtual displays. Extension of this design to other resolutions and field of views is also explored.
