LED TV

LED TV

The term “LED TV” means light emitting diode television. The concept was first invented by Sony with their Qualia LED product array but was subsequently popularized by Samsung when they were the first to begin describing a new line LCD (liquid crystal display) TVs that creatively use LED backlighting as “LED TVs”.

LEDs are basically tiny light bulbs illuminated by the movement of electrons in semiconductor material, and they fit easily onto electrical circuits.

Since the LED TV “invention”, consumer electronic enthusiasts have been awaiting the mass-market arrival of the new technology and the innovation that will come with the new line of products that will have drastically improved displays that offer far more vibrant colors, brighter screens and sharper images for users. Additionally, the energy savings is also going to increase measurably as well as helping continue the trend of reducing the thickness of the existing generation of Plasma and LCD HDTV flatscreens.

The benefits of the LED-backlit LCD TV come from the following important areas:

  • They can produce a very bright image with greater contrast and deeper blacks compared with LCD TVs
  • With Edge-LED lighting they can be extremely slim. Current models on the market are just over 1 inch thick.
  • They consume much less power. About 40% less compared with an LCD TV of a similar size
  • They can offer a wider range of color especially when RGB-LED backlighting is used

The benefits of course also come at a price

A source of confusion for some is the difference between LCD and LED and the question why LEDs shouldn’t be used in lieu of LCD if they have superior capabilities. LEDs in their current form are much too large to be individual pixels on a conventional television. The use of a true LED display is therefore reserved for much larger screens in sports grounds and other commercial locations.

Backlighting helps create contrast on LCD screens by illuminating the background so that the foreground appears sharper. The technology, LED (light emitting diode), is new to the marketplace for a few reasons, mainly cost. A user would currently have to pay two or three times as much for an LCD TV that uses an LED backlight instead of a traditional cold cathode fluorescent lamp (CCFL) backlight

But prices have come down to the point where many technologies start to break into the market, when specialists or enthusiasts are willing to pay. And once LED production rises, reaching heavier volumes, prices will come down — and continue to come down as rivals in the industry expand factories and grab for market share.
