the transparent display enables a virtual image to be seamlessly overlaid over the wearer's real world view. this is especially true when the source image comprises a black background with light color wording or symbology being displayed. black is essentially see-through color, while lighter colored objects, symbols or characters appear to float in the wearer's line of sight. conversely, full-screen images like documents, internet pages, movies which are typically brighter colors can be displayed to look like a large virtual image floating a few meter's away from the wearer.
