How to Buy a LCD TV
I adore big-screen televisions. Particularly the new flat panel models. Before you know it, the majority of people will forgo their traditional CRT TV. sets and have a LCD flat screen TV. This notion really isn’t as weird as it sounds. LCD flat screen TVs are getting progressively more popular, and with a good reason.
Although, you may be wondering, what specifically is a flat screen tv set? Flat screen tv sets have displays only a few inches thick. This makes them captivating and incredibly accommodating. You are able to now hang this kind of tv set on the wall, or place the set in restricted areas. A LCD flat screen tv set can save a lot of room in your house and look attractive doing so. However there are a handful of things somebody should know before he or she acquires a LCD flat screen tv set.
1. Plasma vs. LCD.
Lets take a look at Plasma TVs
Plasma tv sets considerably depend on the fluorescent light bulb. A plasma flat screen is composed of cells. Within each cell are two glass panels separated by a slim gap. Such gaps are packed with neon-xenon gas and sealed in plasma form. The gas is electrically charged when the plasma television set is in use. The gas affects red, green, and blue phosphors. This is what brings forth the TV image.
Given that plasma televisions use the burning of phosphors to make an image, they can be affected by the same disadvantages of conventional tv sets, for instance higher heat generation and monitor burn-in. As well, plasma television sets tend to be quite expensive.
2. Gain knowledge of LCD TVs.
A LCD flat screen television consists of essentially 2 transparent, glass-like materials, which are polarized, and “glued” as one. One of these plates is coated with a polymer that contains the individual liquid crystals. Electric current is then passed over individual crystals. This permits the crystals to pass or block light to produce images. As opposed to the plasma televisions, an external light source is necessary.
LCD flat screen television monitors range from 15-inch variations that are mostly used as computer monitors or secondary TVs, to 46-inch wide screen TVs.
