1. Portable electronic apparatus including a miniature virtual image color display comprising:

  • a portable electronic device with a video data output; and

    a miniature virtual image display physically incorporated into the portable electronic device and includinga viewing aperture,a plurality of image generating structures each including a data input terminal electrically connected to the portable electronic device and a plurality of light emitting devices defining a plurality of pixels assembled in a two dimensional array and each image generating structure forming a different color two dimensional real image in response to data signals received from the portable electronic device, the real images being too small to be easily perceived by a human eye,fixed optical combining means for integrating the different color two dimensional real images into a preferred color, single complete real image, the fixed optical combining means including an optical waveguide having a plurality of relatively flat surfaces with each of the plurality of image generating structures being mounted on different ones of the relatively flat surfaces, the fixed optical combining means further including a plurality of elements positioned on other of the relatively flat surfaces of the optical waveguide to direct and reflect the different color two dimensional complete real images from the plurality of image generating structures into a single preferred color image, andoptical magnifying means for producing, from the single preferred color image, a virtual preferred color image, which virtual image is magnified so as to be viewable and easily perceived through the viewing aperture.
