Abstract

A miniature full-page video display which mounts at least one row of light-emitting elements such as LEDs, a magnifying lens, and a vibrating mirror in a light-tight box having an opening through which the mirror may be viewed. The LEDs are selectively illuminated at points in the travel of the vibrating mirror, resulting in rows of pixels being projected at selected points on the mirror to provide a two-dimensional image. Two or more rows of light-emitting diodes, each of a different color, may be adjacently mounted and selectively illuminated in a manner such that corresponding LEDs are projected on the same spot on the mirror, resulting in a color image. The light box may be a hand-held device or it may be mounted to glasses, a headband or a similar device, and the virtual image appearing at the mirror may be viewed directly through an opening in the box or through a suitable optical system.
