Understanding LED Tech

by Ian Neelson

Cathode Ray Tube systems died out in 2007, when it was replaced by Liquid Crystal Display (LCD) technology. LCD technology function by layering the screen with a sheet of liquid crystal and then shooting white light via small filter-shutters at it. The white light comes from a supply of cold cathode fluorescent lamps in the back of the television and highly accurate calibrations of the shutter-filters are used to define the hue of the light obtained by the liquid crystal. The shutter-filters operate in groups of three, one transferring the red part of the light source, a second passing the blue aspect of the light and the final transferring the green part of the light (RGB). These three sources of light are called sub-pixels, and when looked at from a close proximity, blend together into one color, dependant upon the mix ratios of each colored light let through, to create a pixel.

The aspect ratio of Liquid Crystal Display TVs is among their most blatant flaws. It is seen that even the priciest and classy LCD displays possess a meager max aspect ratio of 1600:1, this is as a result of light having the ability to pass through to the liquid crystal screen even once the television is in it's switched off position. This shows exactly how exact this kind of technology is.

Light Emitting Diode (LED) technology greeted the marketplace lately and erupted like crazy over the last couple of years with the introduction of Organic Light Emitting Diode (OLED) technology. This method is comprised of filling the rear panel with RGB LEDs and then adding a rim of White LEDs around the edge, that act in unison via a diffusion panel to light the TV screen consistently and controllably.

Why might you choose an LED TV?

The Light Emitting Diodes used in this brand-new technology are some of the lightest and slimmest commercially made light sources worldwide and for that reason, the lightest and slimest produced televisions are LED TVs. A number of LED TVs can be as slim as just a few millimeters. In addition to this, the fashion for interior design presently, as you may well realize, is the simplistic, White, Glass, Bold Colors and Piano-finish Black look, which makes these modern, thin and unique televisions excellent for houses in this day in age.

oreover, LCD televisions have major limitations in relation to viewing angle and glare, which may particularly be a problem in substantial open plan rooms. On the flip side, LED TVs combine the LED technology with dense, top quality glass and anti-glare modern technology that diminishes this notably, permitting a substantially greater viewing angle.

Green appears to be the word of the year, and for good rationale too! The polar ice caps are fading and it is the duty of every enterprise to minimize the volume of power and consequently fossil fuels their products and services are designed to consume. LED TVs can output a more clear, brighter and dazzling image than their LCD adversaries, using much less energy.

Finally, the next growing trend in the world is 3D technology. The idea of having wildlife, weather effects and actors/actresses emerging from the television into people's homes is driving the modern world crazy. Should you also like the notion of this advanced technology then a 3D LED HDTV is the ideal option, offering a streamlined design, reduced power consumption, a bright, vivid and powerful High-definition image and of course, the most effective 3D technology available.

LED TVs are very dynamic when it comes to size and can range from modest 21.5 inch monitors, all the way up to enormous 70 inch screens. Even so, personally I feel that the perfect television for any average sized home is a Samsung 55 inch LED TV.
