Digital Trends – Discussed in a presentation at the IFA show in Berlin, Toshiba is diving headfirst in glasses-free technology with a 55-inch flat-panel high definition television. The Toshiba 55LZ2 doesnât require any glasses to view images in 3D and sends separate images into each eye using a technology called âlenticular lensletsâ. In order to accommodate multiple viewers (up to nine), the television uses head-tracking technology to identify faces and direct different images to all the eyes in the room via a built-in camera. In addition, the television is four times the resolution of 1080p at an astounding 3840 by 2160 pixel resolution, otherwise known at Quad-HD.  The television also offers built-in Wi-Fi as well as 2D to 3D conversion.
