THE future of 3D television was a hot topic at CES this year, with only 1.1 million US consumers buying the new technology last year.
While Samsung has committed to ‘‘ a big investment in 3D TV’’ and LG introduced 3D TV with passive, battery-free glasses, others showed off technology viewed with the naked eye.
Sony unveiled three glasses-free 3D prototype technologies at CES.
These included a 24.5-inch OLED model, a 46-inch LCD screen and a 56-inch screen with a 4000x2000 resolution. All had ‘‘ sweet spots’’ in which 3D looked best, and the latter benefited from the greater resolution.
Even more convincing was Sony’s smaller, glassesfree 3D prototypes: a portable 3D Blu-ray Player with a 10-inch screen and a personal 3D TV viewer called the Headman, which looks like a pair of futuristic sunglasses.
There is no delivery date on the new products and Sony will have plenty of competition.
Toshiba also showed off an autostereoscopic 3D TV and Sharp its 3D smartphone, which uses parallax barrier technology to deliver 3D. Jennifer Dudley-Nicholson went to Las Vegas as a guest of Intel.
