3D movies have always fascinated people in theaters. Whether it is an eight-year-old kid or a 90-year-old great-grandparent, this third dimension has always been enthralling for people. Today, this technology has come down from theaters to your home. New 3D television sets are emerging like wildfire in the market.
There are mainly two types of 3D televisions — 3D-ready TV sets and full-3D TV sets. 3D-ready TV sets are televisions which can operate in both 2D and 3D modes. It operates as a normal television but has the additional technology of LCD shutter glasses. These shutter glasses keep opening and closing by redirecting each eye towards the screen to watch a specific moment. Full-3D TV sets are generally LCD sets which only operate in 3D, and not in 2D.
To take advantage of such advanced technology, there are many 3D channels and 3D shows coming soon in the entertainment market. Countries like Australia, Brazil, the USA, etc., have already started their 3D television channels. In the near future, channels like Discovery, Disney, and Sony will also be showcasing 3D programming channels.
These 3D TV sets generally come equipped with some basic technologies like Ethernet, Bluetooth, WI-Fi, USB drives, etc. The heart of 3D TV, though, is its display. There are basically four types of 3D displays. These are stereoscopic, auto- stereoscopic, computer generated holographic, and volumetric displays. Stereoscopic displays provide separate images for the viewer’s left and right eyes to give a 3D effect. This can be viewed by wearing specific glasses. An auto stereoscopic screen has various views of a single screen, so the viewer need not wear the glasses for the effect; the screen itself adjusts with the movement of viewer. The other two technologies have not yet come into common use as they are not so viewer friendly.
