The researchers at Fraunhofer develop microprojector for smartphones

The German research institution Fraunhofer IOF’s researchers have developed hundreds of microprojectors which can be used to project images from smartphones and similar small devices. Even on curved screens, the design of slim LED projection systems also can offer bright images.

The special thing about the LED projector: the entire image displayed is crisp and clear – even if projected at a very flat angle with the beams striking the table surface at a diagonal. Usually, this would distort the picture and make it blurry in places. The researchers who developed the projector at the Fraunhofer Institute solved the problem though hundreds of tiny microprojectors in an array. However, each microprojector generates a complete image.

With smartphones increasingly displacing desktop and laptop computers, they also increasingly are used for presentations. A new LED-based projector could help image details to make out: You position the smartphone in a small cradle on a coffee table, for instance, and it projects the image onto the table top: crisp, bright and A4-sized. If a user wants to zoom in on a portion of the picture, he can swipe the projection with his finger; the same way he can swipe a display screen – the projected image can be controlled using the same principle as the display itself.
