Led Televisions
Cathode Ray Tube systems died out in 2007, when it ended up being superseded by Liquid Crystal Display (LCD) technology
. LCD technology operate by layering the screen with a layer of liquid crystal and then shooting white light through small filter-shutters at it. The white light emanates from a source of cold cathode fluorescent lamps at the back of the TV and is changed color by highly accurate calibrations of the shutter-filters. The shutter-filters operate in groups of three, one transferring the red part of the light, one more driving the blue part of the light plus the last passing the green part of the light (RGB). These three sources of light are called sub-pixels, and when viewed from even a close distance, blend together into one color, dependant upon the mix proportions of each colored light let through, to create a pixel.
Nevertheless, LCD screens do definitely have their own flaws. One example of this is that when LCD televisions are in their powered down state, they still let a tiny bit of light to slide through the shutters, meaning their contrast ratio cannot be above 1600:1
Light Emitting Diode (LED) technology is definitely the clear successor to LCD; nevertheless, as impressive as the LCD successor, LED, is, even it is being expanded upon already with Organic Light Emitting Diode (OLED) technology. This feature consists of filling the rear panel with RGB LEDs followed by adding a rim of White LEDs around the border, that act concurrently through a diffusion panel to light the display evenly and controllably.
So why might you choose an LED TV?
The Light Emitting Diodes found in this new technology are among the lightest and thinnest commercially produced light sources on the planet and thus, the lightest and slimest produced televisions are LED TVs. Some LED TVs can be as thin as only a few millimeters. In addition to this, the fashion for home design at the moment, as you may well realize, is the simplistic, White, Glass, Bold Colors and Piano-finish Black look, that makes these sleek, slim and exceptional televisions excellent for homes in this day in age.
Moreover, LCD televisions have major limitations in relation to viewing angle and glare, which can particularly be considered a problem in considerable open plan rooms. LED TVs counteract this completely by combining the LED technology with thick, top quality glass and anti-glare modern technology that reduces this notably, permitting a considerably greater viewing angle.
Being beneficial for the environment is definitely the contemplation on everyones mind, and for good reason too! The polar ice caps are reduing and it is the job of each enterprise to lessen the level of energy and consequently fossil fuels their products and services are designed to consume. LED TVs were unquestionably fashioned with this under consideration and are capable of exhaling a much brighter and more dazzling image than a LCD TV and with a small fraction of the power.
Finally, the next big thing in the world is 3D technology. The notion of having pets or animals, weather effects and actors/actresses emerging from the TV into peoples homes is driving the world crazy. Should you also like the idea of this advanced technology then a 3D LED HDTV is the perfect option, offering a modern design, reduced power consumption, a vibrant and powerful High-definition image and of course, the very best 3D technology on the market.
LED TVs are extremely dynamic in terms of size and can range from small 21.5 inch computer monitors, all the way up to enormous 70 inch screens. Yet, personally I feel that the best television for an average sized house is a Samsung 55 inch LED TV.
