3D Tv's
These TV sets are high-end and generally include Ethernet, USB player and recorder, Bluetooth and USB Wi-Fi.
Philips was developing 3D television sets that would be available for the consumer market by about 2011 without the need for special glasses (autostereoscopy).[8] However it was canceled due to the slow adoption of customers going from 2D to 3D.
In August 2010, Toshiba announced plans to bring a range of autosteroscopic TVs to market by the end of the year.[9]
The Chinese manufacturer TCL Corporation has developed a 42-inch (110 cm) LCD 3D TV called the TD-42F, which is currently available in China. This model uses a lenticular system and does not require any special glasses (autostereoscopy). It currently sells for approximately $20,000.[10][11]
Onida,LG, Samsung, Sony, and Philips intend to increase their 3D TV offering with plans to make 3D TV sales account for over 50% of their respective TV distribution offering by 2012. It is expected that the screens will use a mixture of technologies until there is standardisation across the industry.[12] Samsung offers the LED 7000, LCD 750, PDP 7000 TV sets and the Blu-ray 6900.[13]
Toshiba has shown 20 and 12 inch autostereoscopic (glasses-free) LCD 3D TV sets for commercial launch, with a 1280x720 resolution. By systematically aligning pixels and adopting a perpendicular lenticular sheet, Toshiba's LCD panel eliminates blurring or the vertical wave pattern (caused by interference in the display cycle) that plagues other autostereoscopic 3-D technologies. The viewing angle is about 40°, doubling the previous approaches. Toshiba's glasses-free 3D TV does suffer initial limitations such as viewing distance and cost, the 12 inch model will sell for roughly $1400. Toshiba are expected to deliver their glasses-free 3D TV on a global scale by 2015.[14]
A September 2011 Cnet review touted Toshiba's 55ZL2 as "the future of television". Due to the demanding nature of auto-stereoscopic 3D technology, the display features a 3840x2160 display; however, there is no video content available at this resolution. That said, it utilizes a multi-core processor to provide excellent upscaling to the "4k2k" resolution. Using a directional lenticular lenslet filter, the display generates nine 3D views. This technology commonly creates deadspots, which Toshiba avoids by using an eye-tracking camera to adjust the image. The reviewers also note that the 3d resolution for a 1080p signal looks more similar to 720p and lacks parallax, which reduces immersion. [
[edit] 3D-ready TV sets
3D-ready TV sets are those that can operate in 3D mode (in addition to regular 2D mode) using one of several display technologies to recreate a stereoscopic image. These TV sets usually support HDMI 1.4 and a minimum (input and output) refresh rate of 120 Hz; glasses may be sold separately.Philips was developing 3D television sets that would be available for the consumer market by about 2011 without the need for special glasses (autostereoscopy).[8] However it was canceled due to the slow adoption of customers going from 2D to 3D.

[edit] Full 3D TV sets
Full 3D TV sets include LG Full HD 3D (1920x1080p, this is, 2K x 1K; and 600 Hz) and Panasonic Full HD 3D (1920x1080p, this is, 2K x 1K; and 600 Hz).Toshiba has shown 20 and 12 inch autostereoscopic (glasses-free) LCD 3D TV sets for commercial launch, with a 1280x720 resolution.
