Minuscule Microprojector Promises Bright, Touchable Displays Of The Future

These Fraunhofer microprojectors are still quite a ways off from being implemented into real phones, but the technology is certainly interesting. Based on an insect's compound eye, the projector is a wafer of tiny LEDs that can twist and turn depending on position. This means there is no "keystoning" and the beams striking the surface will always be "crisp and clear." ?Our projector consists of hundreds of tiny microprojectors in an array, each of which generates a complete image," said Marcel Sieler, a researcher. "This technology, known as 'array projection,' is modeled on nature ? on the compound eye found in some insects ? and with it for the first time we can create very thin and bright LED projection systems with tremendous imaging properties."
