About Flat screen TVs

Plasma screens are not generally available but we will leave the info here for comparison. 

There is a lot of confusion surrounding the introduction of LED, LCD and Plasma Flat screens.

An LED TV is simply an LCD screen which is backlit by LED’s and not florescent bulbs.

LCD’s screens that are backlit have much higher contrast ratios and are much slimmer in design than traditional LCD TV’s.

Edgelit and fully backlit

The first is edge lighting. In this method a line of LED backlights are placed along the very outer edges of the screen. The light is then dispersed across the screen. The advantage of this is that the screens can be made very thin. One major disadvantage of this is edge of the screen tends to be brighter than the centre of the screen and black levels are not as deep as a full array LED screen. Fully backlit LED screens have several rows of LED placed behind the entire screen. This allows certain groups or rows of LED’s to be turned off independently giving darker blacks and more vivid colours. The disadvantage of these screens is that they tend to be thicker than edge lit LED screens.

All LED lit TVs offer a sharper picture, use less electricity, are thinner, and require less warm up time.

LCD and plasma TVs.

Plasma TVs use more power than LCD TVs. Plasmas consume, on average, roughly two to three times more electricity to produce an image of the same brightness as LCD. 

In the last couple of years, plasma TV makers have made some progress--Panasonic claims improvements of 30 percent yearly, for example but they still can’t compete with LCD for energy efficiency. One problem is that in plasma TVs, each pixel is a discrete light source (think of it as a tiny light bulb), so when resolution increases, say from 720p to 1080p, power use goes up as well.Plasma screens are also much heavier in weight because the screen is made from glass. 

A bit about OLED (organic LED)

Light Emmiting Diodes. These TV’s will beultra thin with fantastic contrast andpicture quality whilst using very little power.OLED will be able to be completley flush to the wall using a control box so that you have one, slim cable going to the screen.

Buying a Flat screen TV from The Satellite shop

We stock screens from 19” all the way up to 80” so have got all sizes covered.

When buying a new TV you should consider a few things

Distance you will be sitting from the screen – This gives you an indication on how large a screen you will be able to fit in your room?

Whether you will be watching a lot of sport or movies on the screen – This determines if you need a 100Hz and above screen. These allow excellent motion when watching fast scenes.
