Since death of Cathode Ray Tube (CRT) television sets in 2007, by far the most prominent fabrication technique for TVs is Liquid Crystal Display (LCD). LCD technology function by layering the display with a sheet of liquid crystal and then shooting white light by means of small filter-shutters at it. The white light originates from a supply of cold cathode fluorescent lamps at the rear of the TV and exact calibrations of the shutter-filters are used to determine the hue of the light obtained by the liquid crystal. The shutter-filters work in sets of three, one transferring the red part of the light, one more passing the blue aspect of the light plus the final moving the green part of the light (RGB). These three sources of light are classified as sub-pixels, and when considered from a close proximity, merge together into one color, depending on the mix proportions of each colored light let through, to create a pixel.
The aspect ratio of Liquid Crystal Display TVs is one of their most evident weaknesses. It can be seen that even the most costly and top quality LCD displays possess a measly maximum aspect ratio of 1600:1, this is because of light having the capability to pass through to the liquid crystal display even once the television is in it’s turned off position. This shows just how precise this type of technology is.
Light Emitting Diode (LED) technology approached the marketplace recently and exploded like crazy over the past several years with the release of Organic Light Emitting Diode (OLED) systems. This system consists of filling the back panel with RGB LEDs and then incorporating a rim of White LEDs around the border, that act in unison via a diffusion panel to light the display uniformly and controllably.
So why might you desire an LED TV?
The Light Emitting Diodes used in this fresh technology are some of the lightest and slimmest commercially made light sources worldwide and therefore, the lightest and thinnest produced televisions are LED TVs. A number of LED TVs are often as slim as just a few millimeters. Alongside this, the fashion for home design currently, as you may well know, is the simplistic, White, Glass, Strong Colors and Piano-finish Black look, that makes these modern, slim and unique televisions ideal for homes in this day in age.
Moreover, LCD televisions include major limitations in relation to viewing angle and glare, which often can particularly be considered a issue in considerable open plan rooms. Alternatively, LED TVs merge the LED technology with thick, good quality glass and anti-glare technology that minimizes this tremendously, permitting a much better viewing angle.
Green is very much the word of the year, and for good rationale too! The polar ice caps are melting and it is the job of every business to lessen the volume of electrical power and consequently non-renewable fuels their products are designed to consume. LED TVs were definitely fashioned with this in mind and therefore are capable of exhaling a much brighter and more vivid picture than a LCD TV and with a fraction of the power.
Lastly, the next big thing in the world is 3D technology. The notion of having pets or animals, weather effects and actors/actresses appearing out of the television into people’s homes is driving the planet nuts. If you also enjoy the idea of this futuristic technology then a 3D LED HDTV is the ideal choice, delivering a modern design, reduced power consumption, a bright, vivid and strong High definition image as well as, the very best 3D technology out there.
LED TVs are incredibly dynamic on the subject of size and can range from small-scale 21.5 inch monitors, all the way up to great 70 inch screens. Nevertheless, personally I believe that the perfect television for any ordinary sized home is a Samsung 55 inch LED TV.
