Your Guide to LED TVs

By Dominic Webber


Cathode Ray Tube technology died out in 2007, when it was outmoded by Liquid Crystal Display (LCD) solutions. LCD technology operate by layering the display screen with a layer of liquid crystal and then firing white light via small filter-shutters at it. The white light derives from a source of cold cathode fluorescent lamps at the back of the television and is changed color by precise calibrations of the shutter-filters. The shutter-filters operate in sets of three, one transferring the red element of the light source, a second driving the blue section of the light plus the last moving the green part of the light (RGB). These three sources of light are called sub-pixels, and when viewed from even a close vicinity, blend together into one color, depending on the mix ratios of each colored light let through, to create a pixel.

The aspect ratio of Liquid Crystal Display televisions is among their most blatant weaknesses. It can be seen that even the most costly and top quality LCD displays possess a meager max aspect ratio of 1600:1, this is due to light having the ability to pass through to the liquid crystal screen even when the television is in it's turned off position. This shows exactly how accurate this kind of technology is.

Light Emitting Diode (LED) technology reached the market not too long ago and erupted consistently over the last couple of years with the advent of Organic Light Emitting Diode (OLED) technology. This system consists of filling the rear panel with RGB LEDs and then incorporating a rim of White LEDs around the border, that act simultaneously through a diffusion panel to light the screen evenly and controllably.

So why would you want an LED TV?

The Light Emitting Diodes included in this fresh technology are among the lightest and slimmest commercial light sources in the world and thus, the lightest and slimest produced televisions are LED TVs. Some LED TVs can be as thin as just a few millimeters. In addition to this, the style for interior design currently, as you may well realize, is a simplistic, White, Glass, Strong Colors and Piano-finish Black look, that makes these modern, slim and exceptional televisions excellent for family homes in this day in age.

Furthermore, LCD televisions include major limitations in relation to viewing angle and glare, which can especially be a issue in substantial open plan rooms. On the other hand, LED TVs merge the LED technology with thick, good quality glass and anti-glare technology that reduces this notably, allowing for a considerably superior viewing angle.

Being beneficial towards the environment certainly is the thought on everyone's mind, and for good reason too! The polar ice caps are melting and it is the task of each business to reduce the quantity of electrical power and therefore non-renewable fuels their products are designed to consume. LED TVs were clearly designed with this under consideration and therefore are capable of exhaling a much brighter and more vivid picture than a LCD TV and with a small fraction of the power.

Finally, the next popular trend across the world is 3D technology. The prospect of having wildlife, weather effects and actors/actresses appearing out of the TV into people's homes is driving the modern world nuts. Should you also enjoy the idea of this advanced technology then a 3D LED HDTV is the ideal option, delivering a modern design, lower power consumption, a bright, vivid and strong High definition image as well as, the most effective 3D technology available.

LED TVs are very dynamic in relation to size and can range from modest 21.5 inch monitors, all the way up to massive 70 inch screens. Even so, personally I believe that the perfect television for an common sized home is a Samsung 55 inch LED TV.
