A 3D TV is a television set that comes with the compatibility of three dimensional presentation or sound system. It is a feature found on higher end LED, LCD and plasma TV’s and is a relatively new feature that is steadily gaining in popularity. It employs several 3D techniques such as stereoscopic presentation, multi-viewing channels and so on. It only came into being in 2010, and home cinema systems employ these especially, along with its varied accessories that make the experience all the more worthwhile. 3D glasses are required to view content in the same way it might be viewed in a cinema but apart from these, there are Smart TV cameras, internet adapters, motion detector remotes and so on. 3D TV’s are essentially standard, high definition 2D TV’s, and can be used as so. If one prefers to use it as a normal two dimensional TV set they can, but to turn the set into 3D TV all that is required are the specialized glasses.
In 2D, the picture quality is standard and the functionality or picture quality of the set is not affected at all, as well as other capabilities. The 3D factor is an added feature that may be preferable now to some people but is sure to become a trend in the future, what with such an emphasis on cinematic viewing. The impact of 3D TV is to the extent that programs are especially being filmed to be compatible for 3D viewing. Movies are being re-released into the market to cater to 3D viewing and cinematic 3D viewing is now the norm.
How does it work
3D content works through displaying two separate images of the same scene side to side. When viewed without glasses, the image will seem fuzzy and confusing, and will feel like two different scenes are mixed together to display on the screen. However, when one wears 3D glasses to view a 3D TV image, the images will be intermixed and give off a three dimensional feel. The concept behind the two separate images is that each image is meant to be viewed by the respective eye. The process of “fusing” through wearing the 3D glasses is what makes the display understandable. The 3D TV system relies on the process of visual perception called “stereopsis”, in that, a holographic image. To view content in three-dimension, the following equipment is needed:
- 3D TV
- 3D Glasses
- A 3D sound device
- 3D video content
3D video content is that filmed especially for 3D TV’s, and on which the concept of stereopsis can be applied. Although there is a lot of demand by users to invent the technology in 3D TV where glasses would no longer be required, there is still a certain amount of time left till this is achieved. A 3D source can be a 3D capable disk player or internet video box.
3D viewing is something that has been widely discussed over different forums, but with the introduction of the technology it was discovered that people who suffer from “stereo blindness” cannot see in 3D. Although these individuals will have an acceptable depth perception, they will not be able to perceive the dimension in which 3D is presented. Additionally, prolonged viewing in 3D can cause eyes to weaken ot be fatigued. It has been known to cause headaches and discomfort in viewers, especially if the content produced in 3D is of poor quality.
