Even Tinier SVGA Color Display

erlkonig writes "For those intrigued by tiny displays, Colorado Microdisplay crams 800x600 into a 1.2cm diagonal, under 1g device. Jump straight to the blurb or just look at the pretty pictures. Remember, to get the little chunk of connectors out of the way, you can always mount it (or them) upside-down in your hat brim :-) " How close can the eye reasonably focus on things? That looks pretty nifty, but 800x600 at 1.2cm is gonna have to be real close to those retinas. Still nifty looking.

    Wow! How amazing! How totally and utterly useful! Extremely high resolution images that fit on a fingernail! I can think of literally thousands of uses for the common consumer right away! (military uses obviously)

    Why doesn't someone go and create a 1600x640 palmtop size screen in full colour that uses as little power as a 640x240 16greys screen? That would be useful. Or a 3200x2400 pixel 10 inch screen? I don't want to have to ram some tiny screen into my eye to see a picture, and surely focussing on these tiny screens must be hell!

    The way I know, Matrox cards since the Impression series support multiple cards in the same system, and they usually come with drivers that support that mode. In the Millenium (I have an old version, with a 170MHz RAMDAC), there's a switch that disables the VGA ROM; cards 2-4 must have this in the OFF position.

  13. More useful than it might seem by irongull · · Score: 4

    Check out the specs on the webpage - its actually kinda cool. Lenses in the viewer make a larger virtual image than the screen. The eye can't focus on anything that close without these lenses. It has a 26 degree field of view - that corresponds to a monitor 11 inches in diagonal viewed from 2 feet away. Not great, but certainly useful. And very readable. Additionally, each pixel transmits different levels of red, green, and blue, rather than having three separate pixels for each color. That probably makes for very good image quality. As far as only seeing it through one eye...while this is not ideal, it is also very doable. Microscopes have been like this for years. Of course, stero microscopes are more popular these days, as they allow more detail and reduce eye strain, but it is possible to see very well through just one eye. The trick is to keep the other eye open and focused like the eye looking into the eyepiece, but focus your attention on the image. It is even possible to shift your attention between the two images - useful for taking notes and looking at a magnified image without moving your head.

    Yes, if you look at research on glasses integrated displaies, you will find that they almost universally are looking for super small displaies. One of the documents I was reading mentioned that if they could get a 5x5mm packaged LCD screen, they could integrate it into the boom of the glasses and use a relatively simple folded optical path to make it viewable. The lack of super small displaies has caused a couple of companies to go to alternate methods including scanned lasers and vibrating mirrors.

    Maybe it's time to go back to that old Commodore design, eh? Albeit a bit thinner. You could fit all of the basic computer parts into about that area, with a low-end CPU. Just add a network port.. or even just a regular serial port.. then you could get your e-mail or whatever through it, and have it communicate back and forth with another computer. (or let it use a modem)

    As for power consumption.. well..

    ..okay, here's the idea. If we're going to have people this plugged in and all, why don't we go all the way? I think it'd be neat if you could get on a bus where-ever, and just pop a cord into a socket at your seat, connecting both your power supply and low-bandwidth internet access. The initial communication between your gear and the bus would establish your identity, and if it's a pay-system, setup power/internet costs and what credit card or debit card's going to be used. Then, it'd ask what was your stop, and would activate an alarm to automatically warn you one stop before yours that your stop's coming up. Then--net access. :)
