Toshiba Still Pushing 3D With New 'Glasses Free' 4K Displays
As Toshiba explains it, this is a new technology that uses a low-crosstalk, high-definition LCD GRIN lens, or "gradient-index lens." In a GRIN lens, the refractive-index distribution is formed by applying a voltage to the liquid crystal cell.
"The lens system reduces the abnormal alignment of liquid crystal molecules near the boundaries of liquid crystal lens, reducing crosstalk to 2 percent, against 5 percent in conventional 3D displays," Toshiba explains. "This is achieved by optimizing the orientation of the liquid crystal molecules and the angle of the liquid crystal GRIN lens relative to the direction of polarization of the liquid crystal panel. By combining this technology with a 15-inch 4K LCD panel, 3D resolution has been increased more than fivefold, making it possible to view high-quality 3D images on the same display used for ultrahigh-definition 2D images."
Toshiba is planning to show off its new display technology at the Consumer Electronics Show (CES) in Las Vegas next month. Looking beyond CES, the company says it plans to fuse its new technology with a 2D/3D switching function that can be applied to any screen size and position.
