Department stores like to make sure that their LCD TVs are front and center, knowing the appeal that they will have to the average shopper. Televisions with liquid crystal displays are particularly attractive to those with old standard resolution TVs at home. When compared to the ancient cathode ray TVs an LCD TV’s streamlined, flat-panel look is like something from the distant future. This is enough that many will be tempted into a purchase even in a bad economy. Before impulse-buying one of these televisions, however, there are a few factors to take into consideration.

LCD technology: How it works

The screen on an LCD TV is made of liquid crystal sandwiched between polarized glass. Electricity is applied to the LCD to enable the display of images. These screens have one thing in common with the old cathode ray screens with which most people are familiar: pixels. LCD TVs display images with the use of pixels which are tiny sections of the screen that can display any color and together make up the images up the pictures displayed on a television of computer monitor.

How LCD TV improves the viewing experience

The pictures are better, watching video feels more real and immediate than on an old CRT screen. There is enough of a difference that the first time someone who was used to CRT screens sees an LCD TV in their mind no matter how long ago it was. The high picture quality on LCD TVs is mostly due to the number of pixels presented on the screen. The higher the number of pixels across and from top to bottom, the more vibrant the images displayed will be.

How LCD televisions can save money

LCD technology has been around for a long time, powering digital displays on varied electronic items ranging from clock radios to cell phone screens. It is chosen for these purposes because it uses relatively little electricity and therefore does not tax battery-powered devices. LCD TVs can save money by using less electricity.

Cons of LCD TV technology

In older LCD screens there tends to be some blurring of movement when watching scenes in which there is fast motion. This may be particularly noticeable in sporting events when action is being displayed at full speed. Another problem that is most notable on older models is the limitation in viewing angles. Colors may shift when viewed too far to the right or left of the screen. In newer models these problems have been corrected with the use of LED backlights among other additions.

Plasma vs LCD comparison

Plasma screens are the closest thing that LCD TVs have to competition for picture quality. Plasma is more affordable initially, but this benefit is gradually vanishing as LCD technology gets more and more affordable. At one point plasma was considered a better product due to the problems with viewing angles and motion-blur mentioned above.

The ease of moving LCD TVs

LCDs are less bulky and lighter than plasmas. Not only are they easy to move, they are also easier to mount on a wall.

How good does it look in your living-room?

While this may not be as important to everyone, some people like a TV that fits in with the furniture and other items in their home. The sleekness and stylishness of most LCD TVs tends to improve and add to the décor of most homes.
