Light Emitting Diode Technology

By Sam Sung


Cathode Ray Tube systems died out in 2007, when it appeared to be replaced by Liquid Crystal Display (LCD) technology. LCD technology work by layering the display screen with a sheet of liquid crystal followed by firing white light by means of small filter-shutters at it. The white light comes from a supply of cold cathode fluorescent lamps at the rear of the TV and highly accurate calibrations of the shutter-filters are used to determine the hue of the light acquired by the liquid crystal. The shutter-filters work in sets of three, one transferring the red aspect of the light source, a second passing the blue section of the light and the final moving the green part of the light (RGB). These three sources of light are called sub-pixels, and when considered from a close proximity, merge mutually into one color, dependant upon the mix ratios of each colored light let through, to form a pixel.

The aspect ratio of Liquid Crystal Display TVs is among their most blatant flaws. It is seen that even the most costly and high class LCD displays have a measly max aspect ratio of 1600:1, this is because of light having the ability to pass through to the liquid crystal screen even when the television is in it's turned off position. This reveals just how accurate this sort of technology is.

Light Emitting Diode (LED) technology greeted the market recently and exploded consistently throughout the last several years with the introduction of Organic Light Emitting Diode (OLED) systems. This technique is comprised of filling the rear panel with RGB LEDs and then incorporating a rim of White LEDs around the border, that act simultaneously by way of a diffusion panel to light the screen uniformly and controllably.

So why might you want an LED TV?

The Light Emitting Diodes used in this new technology are among the lightest and slimmest commercially produced light sources on the planet and thus, the lightest and thinnest manufactured televisions are LED TVs. A number of LED TVs can be as thin as just a couple millimeters. In addition to this, the style for interior design presently, as you may well realize, is a simplistic, White, Glass, Bold Colors and Piano-finish Black look, making these sleek, slim and exceptional televisions excellent for homes in this day in age.

Moreover, LCD televisions come with major limitations concerning viewing angle and glare, which may particularly be a issue in substantial open plan rooms. However, LED TVs merge the LED technology with thick, top quality glass and anti-glare modern technology that minimizes this considerably, permitting a much greater viewing angle.

Being good to the environment certainly is the contemplation on everyone's mind, and for good reason too! The polar ice caps are melting and it is the job of each industry to minimize the quantity of electrical power and consequently non-renewable fuels their products and services are engineered to consume. LED TVs were unquestionably designed with this under consideration and therefore are capable of exhaling a brighter and more intense picture than a LCD TV and with a small fraction of the energy.

The production of 3D technology has disrupted the television market dramatically. The perception of having wildlife, weather effects and actors/actresses coming out of the TV into people's homes is driving the planet crazy. If you also like the notion of this futuristic technology then a 3D LED HDTV is the perfect solution, offering a modern design, lower power consumption, a vibrant and powerful High definition image as well as, the very best 3D technology on the market.

As far as size options, LED TVs are available in a range of measurements, from small 20 inch monitors to sizeable 70 inch screens. However, personally I believe that the best television for an common sized house is a Samsung 55 inch LED TV.
