It is widely known that the VPL eyephones are not all they are cracked up to be... the question is, is there a COLOR solution to high resolution miniature monitors... something along the lines of color LCD with RGB input not NTSC. I know color LED monitors are in development but they aren't here yet and when they do come out, they will be expensive as hell... any ideas? -dfRERICHS same net time same net address

When I saw inside the VPL eyephones, it seemed to me that the main problem was the size of the triads. They were big, big enough to be perceived as objects in their own right, which interfered with their contribution to the overall picture. There was a scrim in front of the LCD to blur them out a bit, but of course then you could see the blurring. So, I don't think that the problem is NTSC versus RGB but rather just the inherent resolution of the device. (Yes, I know all about NTSC and its shortcomings.) We really need more pixels on the screens. This can be done one of two ways--by making the screens denser or by making them bigger and changing the optics. Does anybody know what size the LCD's in the eyephones are? The biggest I have seen in consumer electronics is 4 inches, in the Sony LCD TV and the Atari Lynx portable video game. The latter is cheaper and might be useful if one could figure out the driver circuitry.

At the lab were I work, fiberoptic bundles are used to take the image from a SharpVision projector to optics that enlarge the image to about 13" diagonal. Doesn't look too bad blown up to 13", so this technique might work with LEEP optics and head coupled applications. John
