LED Television Technology

What is LED Backlight TV?

LED (Light Emitting Diode) TVs are basically LCD TVs that use a LED backlight system to illuminate the LCD screen. There are two methods to accomplish this:

1) LED edge lighting (Edge lit): In this method, LED lights are placed around the perimeter (sides) only. This allows for a slimmer TV design.

2) LED Backlight (Array lit): In this method, LED lights are placed in the form of an array (across the whole back of the display). Any of the lights can be turned off to correspond with the scene being displayed, and this is why it can project such an accurate picture.

What makes LED TVs better than traditional LCD TVs?

The advantages include:

Superior picture quality

LED TVs will produce deeper blacks due to “local dimming” technology. In comparison, LCD TVs produce a lower picture quality, especially when projecting dark backgrounds. The Cold Cathode Fluorescent Lamp (CCFL), which is located behind the screen, does not actually remain cool. Instead of using all of its energy to produce light, it wastes energy in the form of heat. Further, since the CCFL current flow must be kept at a high level to preserve its lifespan, LCD screens cannot be easily dimmed. This is one of the reasons why LED TVs can operate more efficiently while providing a more precise image quality.

Slim design

LED TVs have an ultra-thin design because of the LED backlight technology. This design makes it easy to mount your LED television on the wall to save space.

Power efficiency

LED TVs use less power than plasma and traditional LCD TVs. In fact, Samsung states that their TVs use 40% less power than a conventional TV. Switching to a LED TV will save you money on your monthly electrical bill and waste less energy on producing heat.

Eco-friendly

LED TVs are considered to be more environmentally friendly than fluorescent tubes because LED bulbs are mercury and lead free. LED TVs can also operate for longer hours (15 times longer than ordinary bulbs). The overall lifespan is much longer than your average TV.

Given that it is still relatively new and that it is a superior technology, LED TVs are a little more expensive than plasma and LCD TVs. Samsung, a leader in the TV industry, has a wide range of LED TVs that range from $1,600 – $3,200 depending on the size.
