It is pretty confusing buying a new television these days. No longer can you just wonder into your electrical retailer and grab a TV off the shelves, safe in the knowledge that the old cathode ray tubes all deliver pretty much the same thing. Nope, now we are bombarded with a host of different options. It used to be that the bigger the screen, the more expensive the television was. Now days, you can easily find a 32 inch screen that cost almost double what a 40 inch screen will cost you, depending on the brand and the various add on features.
Broadly speaking, new TVs support various levels of high definition capabilities. In LCD screens, the large price difference you see is often down to the number of pixels in the television. Having more pixels allows you to get better resolution so the picture looks less grainy. LCD screens work differently to CRT screens. With CRT, an image is projected onto a screen by an electron beam that passes over the screen. Each time the beam moves, it light up special phosphor dots inside a glass tube and illuminates an active portion of the screen. LCD monitors on the other hand use an electric current passing through a liquid, forcing crystals to align so that light cannot pass through them. The more pixels an LCD TV has, the better your quality and the more expensive the tv will be.
It is important when buying a new television to pay attention to the specification because you could easily purchase a large television with a very low resolution which would provide you a poor viewing experience, rather than a smaller tv with a much better resolution that would give you a great picture.
