With everything being miniaturized these days, it only leaves projectors as a doodad still waiting to shrink further. I am not saying that this projector prototype is the smallest in the world, but the technology it features can certainly help it claim that honor. Developed by Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) Germany, this OLED-based Mini Projector depends on the luminance of the OLED panel using lenses. The need of the Digital light Processing (DLP) or LCOS is eliminated by choosing static optical systems. In this case the static system is a combination of five lenses and an 8 x 6mm green light-emitting OLED panel with a 640 x 480 pixel count.
The overall measurements of the projector are 17mm in diameter, 24mm in length and has a volume of 10cm3. This projector can project a 6-inch image from of distance of 30 to 50cm. This technology is desirable for the way it brings about the miniaturization, but it still needs to increase five-fold on the luminance factor to become usable.
