Micro-Projectors May Bring YouTube On-The-Go 143

An anonymous reader writes "A tiny portable projector, about the size of a pack of cards, may soon replace a ring tone as the most annoying thing on the train or bus. These technical innovations can project an image up to 50 inches in size in dark lighting, making them ideal for on-the-road business presentations. They can also be hooked up to cell phones or media devices, though, possibly introducing a whole new level of social intrusion into US culture. 'Digital projectors were once bulky. These new models, though, are small enough to fit into the pocket of consumers who want a big-screen experience from a small-screen device. Some of the models are expected to be on the market by year-end, or sooner. Prices have yet to be announced. Matthew S. Brennesholtz, an analyst at Insight Media, a marketing research firm in Norwalk, Conn., says he thinks the projectors will initially cost about $350, then quickly drop to less than $300.'"

    Can I connect this thing to my HD DVD player? At $300 it's cheaper than buying a real 40 inch screen.

      At $300, it's probably VGA or SVGA res, good enough for DVD, but blow it up too large and you'll be seeing the gaps between the pixels. HD projectors run over $1000. A good 1080p projector can be had for about $2000 now, and they're generally quite beautiful.

            • This feels kinda like nitpicking, but incorrect is incorrect. VHS is not 320x240 per frame. It is (approximately) 320x480 per frame and 30 frames per second for NTSC.

              If you display VHS on a 320x240 screen, then you are only seeing half the image (field 1 is shown; field 2 is thrown away). So VHS is double QVGA resolution, because it has the same number of frames per second (30) but twice as many scanlines (480 versus 240).

          • VHS is analog in the horizontal, so that "320" is sort of meaningless.
            • Not really meaningless, just variable. VHS varies in quality depending upon the speed used. Generally speaking:

              SP == 335 distinct black-and-white dots from left-to-right
              EP/SLP == 305

              The quality of the signal affects the resolution, so that it is not fixed like digital. If you go to a more advanced standard like Laserdisc or Super VHS, then you would see 560 distinct B&W dots. And finally DVD, when viewed through analog S-video, would be about 640 viewable resolution... the maximum that NTSC can hand

              You could, but you would also need a mounting system as well as an enclosure to keep dust of of it...Plus since it already has a fairly fixed focus on the existing screen you may need to remove that set up and finally, well ground kenses of any size can be extremly expensive.

          Maybe you can, but there may be issues as well. It might be designed only to focus within a few inches of the existing screen, because it wasn't expected that a person would try that, it's just easier to make. You would probably void your warranty. You probably can't set it to ceiling mount mode and hang it from the ceiling.

    Until now, projectors needed ungodly amounts of light to project an image bright enough to be usable in a non-darkened room. Either these miniprojectors use some kind of superefficient light source, or that 60" image can only be seen in total darkness.

    • by nguy ( 1207026 )
      If you RTFA, you'll find that they use "dark lighting". Obviously, that's just like regular lighting, except that it makes anything it shines on dark instead of bright. That's the scientific breakthrough that allows them to pack a 60" projector into a box the size of a pack of cards and power it with a single AAA battery. Dark lighting, I tell you, it's the future.
    • Contemporary projectors require ungodly amounts of light because they're horribly inefficient. They're generating a broad-spectrum light (basically light at all visible wavelengths plus some) from an incandescent light source. That's already converting probably 90% of the energy into heat. Then they're running it through (for DLP) three color filters in sequence, so convert on average 67% more of the light energy into heat. Then each filter removes everything except a narrow band of red, green, or blue,
      • Thus no waste light which gets converted into heat.

        Most of it would still be wasted if you're bouncing it off a screen, since it reflects off on some other direction than through your pupil.

        Diode lasers beaming onto the lens of your eye (instead of a screen), now you're getting somewhere.

        But then there's still direct optic nerve stimulation... that would be neat for a lot of reasons. Re-purposing the highest bandwidth link into your brain has endless possibilities.

    • I saw one of these in use a few weeks ago by one of our VPs. He was walking around the room showing his presentation on the walls and ceiling. It was kind of difficult to see compared to the normal projector that was in use. He said the first generation is a little dim, but the second generation for release should be brighter. He also mentioned that you really can't tell a difference in a dark room--we were in a conference room with the lights on.

One of the neat things about LCD displays, plasma panels, and TI DLP mirror systems is that there's no flicker at all, because the display has full persistence. This brings back flicker, big time; all the persistence is in the eye. This idea has been tried before, in bigger displays, and abandoned. So this isn't going to look great, but it will have niche uses.
