Abstract
A portable data source with a binocular virtual image display includes a pair of viewing apertures positioned for binocular viewing, image generation apparatus operably attached to receive data from the data source, and the image generation apparatus including an array of at least 100 by 100 LEDs for providing, from the received data, a real image including either a plurality of lines of alpha-numerics, graphics, or both. The real image has a luminance of less than 15 fL. A fixed optical system produces, from the real image, a pair of virtual images one each perceivable through the pair of viewing apertures.
