Last week Sony, Panasonic, LG, Toshiba, Mitsubishi and Samsung gaze into the big-screen 3-D TVs on display. Video companies are optimistic that 3-D TV will be huge success this year. To gain a clear understanding of what specifically defines a 3-D TV and what you need for a full experience.
In order to display a full-frame image in 3-D, you need an extremely high frame rate, so usually the TV must be capable of a 240-Hz refresh rate. The TV also needs to support HDMI 1.4, the latest generation of HDMI, which will transmit the massive amount of data necessary to process and display 3-D images. Most 3-D TVs also include a transmitter that can synchronize with the 3-D glasses. The transmitter, usually in the middle of the TV, synchronizes with active-shutter glasses so that the glasses’ lenses show and hide the left and right images at the proper frequency (120 Hz for each eye). Pricing for these glasses has yet to be determined, but is probably in the $100 to $300 range.
The manufacturers are confident that consumers will come along for the 3-D ride sooner or later. The Consumer Electronics Association estimates that 4 million 3-D TV sets will be sold in 2010, most of them in the fourth quarter.
