Head mounted stereo displays for virtual environments and computer simulations have been made since 1969. Most of the recent displays have been based on monochrome (black and white) liquid crystal display technology. Color LCD displays have generally not been used due to their lower resolution and color triad structure. As the resolution of color LCDdisplays is increasing we have begun to use color displays in our Eyephone. In this paper we describe four methods for minimizing the effect of the color triads in the magnified images of LCD displays in the Eyephone stereo head mounted display. We have settled on the use of wavefront randomizer with a spatial frequency enhancement overlay in order to blur the triacis in the displays while keeping the perceived resolution of the display high.
