CES 2011: TVs at CES 2011 LG glasses-free 3DTV
Of all the prototype glasses-free 3D TVs at the CES, the LG was the most impressive. Clearly using a different technology from the Sony and Toshiba efforts, the 3D effect looked impressive when viewed head-on. Images looked comparatively sharp, bright and definitely delivered on the depth front.
LG 3D effect
The TV panel is made up of different layers – an optical layer splits the left-right images and a film layer merges them back together again. It should work with regular 3D Blu-ray and 3D broadcasts.
Yet, like the other prototypes it is extremely limited by viewing angle and distance. The 3D effect can only be seen from 12 to 16 feet away and around a 20 cm angle off- centre. LG claim that’s a big improvement over the last couple of years. Until recently it only worked head-on only.
Sorry no 2D
But the main drawback of the LG model? Unlike the Toshiba and Sony prototypes it can only display 3D images - the screen filters mean 2D would appear blurred. LG has a big hurdle to climb to get a working 2D/3D prototype to market but insisted that was their intention rather than releasing a 3D only TV.
