Fraunhofer Institute Improves Images on Curved LED Screens with Micro-Optical Array Projectors

Projecting images on curved screens poses a dilemma. The sharper the image, the darker it is. A novel optical approach brings brightness and sharpness together for the first time on screens of any curvature – and additionally allows about 10,000-times faster projection rates. Researchers will be presenting their technology November 4-6 at Vision 2014 in Stuttgart. (Hall 1, Booth G42)
