Apparatus and method for generating full-color images using two light sources

摘要

A miniature, full-color display includes two rows of light-emitting elements that are both selected to emit light in substantially non-overlapping wavelength ranges comprising a blue-green wavelength range and a red wavelength range. The light-emitting elements as well as a magnifying lens, and an oscillating mirror are placed in a light-tight box having an opening through which the mirror may be viewed. The light from the blue-green elements is filtered by a filter which transmits either blue or green light depending on the mirror movement. The light-emitting devices are selectively illuminated as the mirror moves to create a full-color, substantially planar, two-dimensional image. The light box may be sized to be hand-held, or may be capable of being mounted to a pair of glasses, a headband or similar device.
