What is 4K TV Features
What Is 4K TV, there are a lot of different screen types out there, all working in different ways to produce the same results. The strengths and weaknesses of each technology are to be considered before buying a 4KTV, these are some of the answers to What Is 4K TV.
There are a few main screen types available, all working to produce your required results. The types change as technology progresses, a good example is that all LCD TV’s (liquid crystal display) were backlit by CCFL (cold cathode fluorescent lamps) but this technology has moved on and now the LED method is the more common screen type.
LCD TV’s are still widely available as obviously the new technology is more expensive.
A quick summary of this change is that the CCFL (cold cathode fluorescent lamps) have been the backlight of all 4KTV’s since whenever but now superseded by LED’s.
Light Emitting Diodes (LED) which in the most recent 4K TV’s, are positioned directly behind the screen in an array.
These LED’s improved contrast and power efficiency but are more expensive, so then along came the Edge-lit LED technology in which the difference is that the LED’s are mounted on the edge of the panel, hence called Edge-lit LED.
This Edge LED allows for a superior contrast and a much slimmer screen but the overall picture quality is not as good as the standard LED type. Again this new Edge LED is cheaper so there are a lot of Edge LED TV’s out there in the market.
But again things have progressed and the OLED TV (Organic Light-Emitting Diode) with backlighting has come along and again better but as expensive, so it’s not yet been taken up by all the manufacturers except LG Electronics who have taken up this TV type.
All these technologies have progressed the What Is 4K TV to where it is today.
4K Ultra HD Televisions and 3D
The wide reaching popularity of 3D movies at a theater, films like Avatar, Alice in Wonderland and many others have created somewhat of a demand for 3D capability for the home television.
The newest 4K Ultra HD 3D televisions are capable of displaying high quality 3D content, with pictures easily rivaling those of a theater.
As you may be aware 4K Ultra HD televisions have four times the resolution of Full HD televisions, this resolution gives you a 3D picture of a new quality level, which was not possible with a regular 3D HDTV.
During 2014 and 2015 the overall 3D content has increased as this 3D content is now available from so many different sources like Comcast, DirectTV, Blu-ray 3D discs, PS3, ESPN, and PS4 3D games.
What is a 3D Ready TV? The 3D television is the same as a normal HD television set except that it has a built in IR (Infrared) or Bluetooth transmitter to transmit the signals to special 3D glasses. This 3D is called Active 3D as opposed to the other type of 3D that uses polarized glasses and is called passive 3D.
The 3D Ready TV also has special programs on board which can process the 3D programming especially, and to convert 2D (regular HD) into a simulated 3D.
There is now additional 3D content from many more sources additionally Sports have become a big area for 3D, with ESPN having launched ESPN 3D which has introduced 3D sports programs which include world cup soccer, the NBA finals, golf and much more.
Blu-ray 3D Players have now also appeared that can give you full HD in 3D format.
Note! 3D Glasses are not required to view regular HD programs. So even if you are not going to initially buy accessories (glasses and 3D blu-ray players), you can still enjoy your 3D TV as a normal HDTV for high definition programming.
What’s new for 2015 3D TVs?
Well for 2015, you won’t find many 1080pixel 3D HDTVs, as a big change is happening. Almost all 2015 3D TVs now are 4K Ultra HD TVs.
Ultra HD having the much higher resolution than regular HDTVs. This makes a huge difference on the quality of 3D. We have viewed 3D in 4K, and we felt it was as good or better than the movie theater 3D. Curved 4K 3D TVs are also available for an even better immersive experience.
So for 2015 if you want a 3D TV, it will probably be a 4K Ultra HD set.
