Projections using PDAs or other handheld devices like a smartphone weren’t quiet possible until now, but that is all going to change with the Mini Beamer. The Mini Beamer is a wonderful innovation from IOF and HYPOLED, that uses no external lighting source for projections and because of this has a minuscule size. Currently a prototype, the Mini Beamer measures 2.5 centimeters in length and has an overall diameter of 1.8 centimeters.
These numbers are so small that the Mini Beamer can be easily embedded into a cellphone. Also, this mini projector requires very little amount of energy, therefore even an integration into a device does not eat up heavily on the battery.
The Mini Beamer is actually an organic OLED display capable of producing a monochromatic image with a brightness of 10,000 candelas per square meter (make that half for colored images). The prototype currently uses glass lenses but the researchers are keen to develop an optical system using plastic lenses to bring the productions costs down. In the future you could project your stored images onto any flat surface, thanks to this novelty.
