Owning a 12v TV can be a real pleasure, but knowing which one to buy can be a minefield. Here I hope to enlighten you to the common uses and also give you something to think about before you buy one.

What is a 12v TV and why would you need one?

A 12v TV are usually designed and to be powered from a battery such as a car battery, but can be used with power from the mains. A 12v TV has much lower power consumption than a traditional TV which you would power from the mains. This will allow you to watch your TV for a much longer period of time then if you hooked up a traditional TV to a battery.

Most people think of 12v TVs to be used in a caravan or motorhome, but you can find a 12v TV in much more diverse places these days, such as trucks & Lorries, kitchens, tents (camping), cars in fact anywhere where you need a small low power TV.

The quality of 12v TVs these days has improved greatly over the last few years with improved picture, improved tuning, on board digital TV tuner and more compact, lighter devices.

Some people still use an inverter to lower the voltage of their traditional TV which is then wired up to a battery. This allows their TV to work, but the viewing time is much, much lower than if you buy a full 12v TV.

There are many different makes and models of 12v television on the market. They come in all shapes, sizes and prices. They also have very different functionality. Some contain a DVD player, some are full HD and some have remote controls. We suggest that you give it some thought about what you really do with your new 12v TV. Do you plan on using your TV to watch DVDs or just digital TV? Or if you're planning on travelling abroad is easy tuning a priority for you.

Something else to consider is the size of the television. If you have lots of space then this may not be an issue, but if you're planning on using your TV in a confined space than size is something you must consider.

Most 12v TVs come with holes on the back which will allow you to mount this on a wall which will save you space, but security is something else you will need to consider if you're going to mount your TV on a wall. You can buy special detachable television mounts so when not in use or if you're leaving your TV in a vehicle for some time you can remove and hide the 12v TV.

Also if you have a very large TV then attaching the television from the wall may be an issue. How many people who will be watching the TV at one time is also something to consider as if your 12v TV is too small then it will make viewing difficult if there are a lot of people watching.

What makes 3D televisions popular nowadays? A 3D television is a TV set that uses techniques of three-dimensional (3D) presentation such as multi-view capture, stereoscopic capture, a 2D-plus-depth and 3D display viewing device that allows a television program to project a realistic 3D field. Some popular 3D television brands on the market are Samsung, Sony, LG, Panasonic and Phillips.

A Brief History of a 3D Television:

It was in the late 1890s that William Friese-Greene, a British film pioneer, filed a patent for 3D movie process. Two combined images are produced by the brain when the film is viewed stereoscopically, creating a 3D depth perception.

The first stereoscopic 3D TV was demonstrated by John Logie Baird on August 10, 1928 in the premises of his company in London, England. A variety of 3D television was pioneered by Baird using the electro-mechanical technique and cathode-ray tube. In 2009, television stations aired 3D serials using the same technology utilized in 3D movies.

Understanding the 3D Technology:

Producing and displaying 3D moving pictures are made possible by several techniques. The most basic requirement of this technology is displaying offset images separately filtered to the right and left eye. The most popular techniques to achieve this are requiring viewers to wear eyeglasses that would filter offset images separately to each eye and allowing the lightsource to divide the images directionally into the eyes of the viewers, requiring no glasses.

A widely accepted method to capture and deliver 3D video is stereoscopy. This technique captures stereo pairs in a double-view setup. The cameras, mounted on each side, are separated similar to the distance as between your pupils.

There are television sets that are 3D-ready. This means that these television sets are capable of operating in a 3D mode, as well as 2D mode, in conjunction with LCD shutter glasses and set-top boxes. The 3D-ready television tells the shutter glasses which of your eye should view the image being shown at the moment, thus creating stereoscopic images. Meanwhile, full 3D televisions are designed to be viewed in blackened room to allow depth to images.

Some 3D TVs to Consider:

One good example of a 3D TV is the Samsung UN46D7000 46-Inch 108OP 240Hz 3D LED HDTV in silver. This television is Samsung's answer to TV connectivity, combining entertainment and communication. It has built-in Wi-Fi and Skype and allows you to make real-time video calls easily and quickly without compromising the video quality and sound clarity. Some notable features of this TV are Smart TV advanced online connectivity, a wide array of applications, enhanced web access, video depth and sound clarity.

Another 3D TV worth considering is the Samsung UN46D6400 46-Inch 108OP 120Hz 3D LED HDTV in black. The Smart TV feature of this equipment allows you to customize your entertainment. Smart TV works by delivering a web-capable portal and Samsung applications and providing search contents both on your television and online. This impressively thin television is designed to provide viewers with an immersive experience during viewing time.

The Sony XBR 46HX929-46 Bravia 3D LED-backlit LCD TV and Blu-ray may be quite expensive but worth every single centavo you spend on it. The Sony Bravia line ranges from 40 inches to 55 inches televisions.
