If you are referring to microdisplays, the actual display modules appear to be cheap, at lest the kopin ones are: http://www.kopin.com/html/cyberdisplay_pricing.html CyberDisplay 320 Model 290 Monochrome Optical Engine $105 (Display/Backlight, and focusing mechanism) CyberDisplay 320 Color Video Optical Engine $135 (Display/Backlight, and focusing mechanism) But these are just the display and backlight, optics and hardware driver are needed, neither of these are trivial. Micro-Optical has extremely small optics, would be hard to come even close building your own. And Ed tells us that its a lot of work to build a driver, requires custom circuitry and writing a framebuffer driver. The above displays are only QVGA (320x240) and I wouldn't want to bother with custom drivers unless it was double that to VGA (640x480). Kopin has a VGA CyberDisplay but they don't list prices. Kopin doesn't seem to have what I want (VGA mono), but they have a 1280x1024 CyberDisplay. They have a 1280 Mono eval kit, and it includes a complete PC (give me a break ... don't sell me something I don't need) The MicroDisplay VGA mono eval kit looks very interesting, but I don't thing these are easily obtainable. The driver board is 2.75" diagonal and presumably it runs a lot leaner than the Cy-Visor which uses the MicroDisplay field sequential color displays. http://www.microdisplay.com/products/monokit2.html Prices on the eval kits from MicroDisplay used to be $1200 for the VGA mono and $2500 for the SVGA color. The optics are large though, so custom optics would be needed to get anywhere close to micro- optical radical packaging. Somebody also mentioned a while ago that the MicroDisplay kits were no longer available. I assume that this company also sells just the displays, but I doubt that they will sell them unless you buy an eval kit. Colorado Micro has some interesting stuff too, but I think that eval kit prices are steep, and custom drivers will be needed to make them feasible for wearing. Their analog SVGA kit looks to have a nice eyepeice, but the driver is big, and I don't think these kits are cheap. http://www.comicro.com/product/product_eval/index.html (SVGA analog) http://www.comicro.com/product/8x6d_evalkit.html (SVGA digital) http://www.comicro.com/product/qvga/qvga_eval.html (QVGA) InViso also has some eval kits. The OptiScape eval board is an SA-1110 CPU board! Interesting but annoying at the same time. I wonder if you can use the board AS your wearable. Whoa, pricing on these kits are $6,500 and $18,000. I find it hard to believe that they will sell e-Glasses for $600. http://www.inviso.com/eval_kits.html http://www.inviso.com/order.html DisplayTech has a QVGA kit that allows input from NTSC, PAL, or VGA. No idea on pricing or size of driver etc. http://www.displaytech.com/products/personalview.html These are all of the microdisplay eval kits that I am aware of. Anybody know of others? If you are referring to LCDs in general, you can do QVGA with the Seiko Vitrium chip-on-glass, but you'll probably need to build a driver because the eval kit boards are big, and its a parallel port interface that requires custom software driver. You can do TFT VGA panels in the size range of 4 to 7 inches digonal for around $500-$800, and many SBCs have the video driver hardware to support these directly. On the low end you can interface to text/graphics LCDs through RS232 port. I am about to start working on a PS/2 interface to microcontroller along with text/graphics LCD, and make it a serial terminal (just run getty on linux). I will start with a small 4x20 character LCD for testing then move to something bigger like these: http://www.noritake-elec.com/graphic.htm The GU256x128 in particular does 16 lines of 42 characters text, this would make a nice serial terminal, and it would be bright, good for outdoor viewing. http://www.noritake-elec.com/v6a.gif The CCFL displays at NCD might also make good serial terminals. http://www.controlanything.com/html/lcdlist.htm Take a look here for an extensive but out of date collection of mobile display sources. http://home.earthlink.net/~wearable/#Displays -- Doug -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org please, Please, *PLEASE* don't subscribe through a forward/false domain
