    However, LCDs are getting cheaper, and OLEDs are on the horizon. I don't want an empty box, I don't want a box at all. I want a thin panel which I can put on a wall.

    Optimally we would get something that comes in rolls and can be cut to size. Then you just stick a piece of fiber on it anywhere, and have it communicate with you optically. Every pixel should have its own driver circuit, and they should speak to one another with various shortcut buses woven throughout the material. It should also be capable of speaking to other pieces of the material if you make it overlap. This way we could have large (if initially slow) displays. Then you just need a discovery method to determine the properties of the display, and a resolution-independent display method.

    In the meantime; I don't want an empty box. If I have a MEMS-based display, it had better be painting the image directly onto my retina, which is much more useful anyway. I'm willing to put on goggles, though that shouldn't be necessary; within a certain (smallish) range of motion it should be able to track me just fine.

    If we DO use a MEMS mirror-based display, we should be using a large number of mirrors to minimize the depth of the thing and also to maximize refresh rates.

      I think one long-term problem with relying on panel-like technologies is that the will require a lot more material. Looking around my apartment, I've got a lot of empty walls, which I'd love to have something on (posters and whatnot). It'd be great if I could have some kind of cut-to-size material like you describe that I could simply put anywhere I want and have it display some kind of (presumably non-static) information. But in that scenario, I've got to have maybe four or five square meters of material to cover all the area I'd like.

      Now imagine another scenario where I've got something either overlaid on my vision or inserted directly into the optical signal (progress is being made there, too!). Now I've just got a small device coupled to a computer (which I'd also need in the first scenario) that can change what I see based on where I look. If I look at my north wall, I see a Kraftwerk poster; if I look south, I see the news. Significantly less material and less maintenance, I imagine, but at the cost of significantly more advanced technology. I suspect the panel approach will win in the short term, and will certainly face less social or ethical resistance.

      Any other thoughts on this?

      It should be possible to do this either way soon, with recent advances in printed circuits, OLED, and MEMS technology. I'm sure it will continue to be expensive for a while, though. It would be nice to have even if it were extremely slow, though, so maybe someone will come up with a cheap, slow way to do it that requires some kind of computationally intensive encoding process to display graphics... That would be good enough.

      But anyway, you are quite right that you could use a series of projectors and head+pupil tracking to just overlay the video on your vision somehow, or yes to insert it directly into the signal. The latter, however, will likely always require hardware actually on your head. The former is not a bad idea, though it is seriously computationally intensive, requires some very good cameras, et cetera. All of it is getting cheaper but I still think a simple display with a simple hardware interface is our first step.

      There are also some decent reasons to only use a wallcovering; For one, it doesn't require any special hardware on your head. Two, any number of people who can physically view the surface can view the contents. You could always augment it with a projector or goggle system to add private content. And three, you could also lay the material down on cars and anyone could see them. Four, people whose eyes are not factory equipment but are learning to see via machine assisted devices will probably not be able to use a projector system.

      I guess the first step for a system like this is to be able to inexpensively make some kind of MEMS array which can be treated like wallpaper and which can flip over squares for color/no color, or at least black/white to begin with. Maybe you could just do something with an inkjet circuit printing process and little hollow glass beads of liquid crystal. Then you could print to the edges of the paper, and have contact patches which got glued together from page to page for communication.

    If you assume that Moore's Law holds for what you want to push, and NOT for its competition


    Its quite a reasonable inference actually. The reason that Moore's law holds is that smaller and smaller diameter fabrication processes are developed, so that an integrated circuit can be made smaller, and thus also cheaper, and furthermore reduce power consumption, heat production, and speed. Now, the MEMS projection chip does not have to be any particular size, so as process technology becomes more advanced, the cost to produce these will go down with everything else. But a conventional LCD, in order to be useful, has to be a certain size, and, for any given resolution, has to have a certain number of pixels. Of course, technology advances do help LCD's, but its no use to the user if 10 years from now you can get a 5mm desktop LCD display for $10 with the same resolution as the 15" display you want now.

      The "sweep the laser beam spot across the big screen" approach to image projection doesn't work very well. The effect is something like a laser light show; the strobing effects are visible. And if you crank the spot intensity up to a good level for the whole screen, the beam is dangerous. You're really abusing persistence of vision at that point. Nor do you need MEMS for that; just moving mirrors.

      Generating a whole line of image at once (not just one pixel), then scanning that across the other axis, does work. The Scophony system did that in the 1930s, using a very neat technology worth looking up. MIT revived it in the 1980s.

      MEMS devices are widely used for digital projectors right now, but there's a tiny moving mirror for every pixel, and no scanning at all. That's why those images look so steady. If you saw Star Wars in digital, you probably saw it on a TI projector using an array of MEMS mirrors.

      In addition, MEMS isn't limited to just projecting and capturing optical images. That same MEMS chip can be used as an extremely-fast processor.

Most home and small business DLP projectors use a single DLP chip and a rotating color wheel. Personally, the technology behind DLP, an array of mirrors, is more impressive than a single moving mirror.

    Coincidentially, TI's design is the result of their attempts to create exactly the single-mirror type of system described. They gave up on that approach because of what they learned about physical behavior at the nano-level. The mirrors tended to stick on one position or the other. So they turned that from a liability to a virtue. Instead of trying to directly analog modulate the light, they decided to use time modulation.

    DLP is no less cool because it actually exists, and is in use in thousands of projectors.
