What if the size of your Android's screen didn't matter? What if you could project Youtube videos and games from your Android to a wall or screen? One company, called Alps Electric, wants to turn the dream of portable projection into a reality.
Alps Electric has created a micro-projector lens that is so tiny, it can fit on the tip of a pencil. The tiny lens named FLGS3 has a light transittance of 73% and can operate with wide-angle laser diodes. Alps Electric claims that the FLGS3 is the smallest lens in the industry. Their small size makes them excellent candidates for use in smartphones.
I think it'll only be a matter of time before someone finds a way to integrate a mini projection system on an Android. Certainly the idea of being able to beam images from a smartphone to a wall is incredibly exciting, and it would make it a lot easier to create amazing prototypes like this.
