Washington, June 25 (ANI): Those who love watching their favourite football teams in action on the big TV screen can now enjoy the same experience even when they are out on the beach-all thanks to mini beamer in cell phones.
Cellphone TV is coming closer as the mini beamer would make it possible to create a public viewing event on a small scale - for example on a white bathing towel by the side of a lake.
Developed by research scientists at the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena in cooperation with their partners in the EU project HYPOLED, the mini projector does not need an additional illumination system like conventional beamers.
As 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 centimeters long, has a diameter of 1.8 centimeters 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," said 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 and for colour images the brightness is about half that level.
The researchers are exhibiting a monochrome prototype at the Laser World of Photonics trade show from June 15 to 18 in Munich. (ANI)
