Nintendo took the wraps of the Nintendo 3DS yesterday at the E3 2010.
The Nintendo 3DS features a 3.53-inch top 3D screen and a 3.02-inch bottom touch screen. Nintendo did not reveal what technology is behind the 3D display of the 3DS. The screen is using autosteroe technology which does not require glasses to see the 3D effect.
There is one company that has been unveiling small stereoscopic displays: Sharp. Just in April Sharp unveiled a 3D touchscreen display, that apparently Nintendo is not using in the 3DS as only the bottom 2D screen is touch enabled.
But Sharp also makes a 3D display without touch. Sharp is also the display provider of the DS and DSi. TechOn points out that Sharp also offers a stereoscopic camera module. Nintendo is likely to source both the 3D screen and the camera module from Sharp for the 3DS.
