Thickness Solution

After we discovered Endlighten just today we started looking into potential solutions that use the technology. Jason discovered a project being undertaken by Mark Moissette at kaosat.net. From his research, it appears that it is possible to use a single sheet of Endlighten as both a backlight for an LCD and an infrared plane for touch sensing. The application of this is the ability to place the LCD and a thin protective layer directly over a single sheet of endlighten resulting in a fully functional display (sans imaging) without the hassle of using the original LCD backlight.

Furthermore, we have finally found the solution to removing the space-expensive camera from the design. We were previously looking into sensor array solutions that would fit between the backlight and the lcd. This wasn't possible without major engineering because this sensor array would have had to been almost completely transparent. However with this new design by Mark Moissette the sensor-array can be placed under the backlight. The following diagram was taken directly from his blog:

We finally have found a method for creating super thin displays using the same original multitouch principles but replacing the large projectors and cameras with lcds and sensor arrays. Too bad we can't say the idea was our own, but it's still good news. This new method requires a few parts that we don't have however, so the current project will still use the original camera-based method. Future projects will almost certainly use this new method.
