Toshiba will display new screen technology at CES 2015 that can switch from 3D mode in full HD (1920 x 1080) resolution to 2D mode in 4k Ultra HD (3840 x 2160) resolution. The 15-inch display, developed at this point for commercial use, maintains brightness levels in 3D mode and image quality when in 2D UHD mode with Toshiba’s new low-crosstalk high-definition liquid crystal GRIN (Gradient-index) lens system. And, the display’s 3D mode doesn’t require viewers wear 3D glasses, so switching from one mode to another is relatively painless. Toshiba plans to incorporate the switching technology into other screens and sizes, and expand the feature into B2B industrial and medical products where glasses-free high-definition 3D displays are used. For the consumer market, Toshiba has developed glasses-free 3D TVs and laptops, but interest in 3D displays has dwindled as 4k ‘Ultra HD’ screens have emerged. However, in industrial markets and the medical industry 3D displays maintain their usefulness.
