The Science Behind LED Televisions

By Dominic Webber


Ever since the death of Cathode Ray Tube (CRT) tv sets in 2007, by far the most superior manufacturing technique for TVs is Liquid Crystal Display (LCD). LCD technology function by layering the display with a layer of liquid crystal and then shooting white light by means of small filter-shutters at it. The white light comes from a supply of cold cathode fluorescent lamps at the back of the TV and highly accurate calibrations of the shutter-filters are used to determine the color of the light obtained by the liquid crystal. The shutter-filters operate in groups of three, one transferring the red aspect of the light source, one more driving the blue section of the light and the final moving the green portion of the light (RGB). These three sources of light are called sub-pixels, and when considered from even a close proximity, merge mutually 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 TVs is one of their most evident flaws. It is seen that even the most expensive and high class LCD displays possess a measly maximum aspect ratio of 1600:1, this is because of light being able to pass through to the liquid crystal screen even when the TV screen is in it's turned off position. This reveals exactly how exact this kind of technology is.

Light Emitting Diode (LED) technology greeted the market not too long ago and exploded continually throughout the last few years with the introduction of Organic Light Emitting Diode (OLED) systems. This method is comprised of filling the back panel with RGB LEDs followed by adding a rim of White LEDs around the border, that act simultaneously via 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 good towards the ecosystem is definitely the contemplation on everyone's thoughts, and for good reason too! The polar ice caps are fading and it is the task of each business to minimize the amount of power and therefore non-renewable fuels their products are engineered to consume. LED TVs can output a more distinct, brighter and dazzling picture than their LCD competitors, using much less electricity.

The production of 3D technology has disrupted the television industry dramatically. The prospect of having pets or animals, weather effects and actors/actresses emerging from the television into people's homes is driving the planet nuts. If you also enjoy the very thought of this advanced technology then a 3D LED HDTV is the ideal option, providing a streamlined design, lower power consumption, a bright, vivid and strong High-definition image as well as, the very best 3D technology attainable.

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.
