Cell Phones to Project Images on a Wall:

Now, It is possible that we can project the images by using Cell phones with the help of Miniature Devices...

A new one-cubic-centimeter projector head that can be integrated into a portable computer or mobile telephone has been developed by Lemoptix, a spin-off of Ecole Polytechnique Federale de Lausanne (EPFL), and the Maher Kayal Laboratory.

Little Energy will be required to projector requiring on average 30% less current than the matrix- or LED-based technology currently available on the market.“This micro-projector functions using tiny mirrors of less than a millimeter’s thickness. Positioned on a silicon (wafer) disc, they reflect red, blue and green laser beams”.

The device, contained in a tiny glass case (3 mm x 4 mm), oscillates so rapidly that the beam can scan a surface up to 20,000 times a second. In August, Maher Kayal’s team was able to generate a color image in VGA resolution (640 x 480px) for the first time.

The improved brightness and contrast will enable it to replace LCD screens. The Lemoptix team envisions an interactive version that would allow you to touch the projected image to zoom or change screen.
