ABSTRACT:
A miniature display projection system, for attachment to a pair of spectacles or sunglasses, or made as an integral system combination, display projection and sunglasses. A miniature opto-electronic display panel is driven by micro electronics to generate bright luminous display images, providing useful displays such as time of day or even television images. A novel optical projection window is used to project the display, such that to appear superimposed onto the normal field of view of the spectacles or sunglasses wearer, when the display panel is activated. When the display panel is not active the normal field of view is seen unhindered.
