Date posted: 04/06/2009 Looking at photos on a cellphone display can be somewhat arduous. A new mini beamer will make it easier. The beamer is so small that it can be integrated in a cellphone or a PDA. As it does not need an extra light source it also conserves the battery.
The mini projector was developed by research scientists at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena in co-operation with their partners in the EU project HYPOLED. Unlike conventional beamers it does not need an additional illumination system. Because the beamer can operate without an extra light source it offers a number of advantages: Firstly, it takes up little space. The prototype is 2.5 centimetres long, has a diameter of 1.8 centimetres and can be easily integrated in a cellphone or a PDA. Secondly, the device needs very little energy and therefore does not overtax the battery. ?The key component of the projector is an organic display, or OLED, developed by our colleagues at the Fraunhofer Institute for Photonic Microsystems IPMS in Dresden,? says Dr. Stefan Riehemann, group manager at the IOF. Currently the OLED display produces a monochrome image with a brightness of 10,000 candelas per square meter; for colour images the brightness is about half that level.
