Massachusetts Institute of Technology (MIT) researchers have developed HR3D, a new method for glasses-free three-dimensional (3D) displays. The researchers say their method could double the battery life of devices such as Nintendo's 3DS portable gaming system, which currently has a battery life of about three hours, without reducing screen brightness or resolution.

The new technique also could expand the viewing angle of a 3D screen, making it practical for larger audiences. Nintendo's 3DS screen consists of two parallel liquid-crystal displays. The front display acts as the parallax barrier, forcing the device's backlight to be twice as bright, which drains the battery. The HR3D system uses pinholes for the parallax barrier, instead of the vertical slits used in 3DS, reducing battery usage and increasing the number of angles the devices can be viewed from.
