“A South Korean company developed a coin-size laser video projector module that can fit into portable gadgets such as mobile phones and digital cameras.”
Iljin Display has come up with a projector that can be built into a cell phone. Iljin expects about 5% of cell phones will offer a built in projector by 2010.
On a humorous note, 2020 will be an even more interesting year. In 2020, Airports will ban cell phones with built in light sabers. 🙂
