Understanding LED Technology

By Sam Sung


Cathode Ray Tube systems died out in 2007, when it was outdated by Liquid Crystal Display (LCD) solutions. LCD technology function by layering the screen using a sheet of liquid crystal followed by shooting white light via small filter-shutters at it. The white light originates from a supply of cold cathode fluorescent lamps in the rear of the television and precise calibrations of the shutter-filters are utilized to establish the hue of the light received by the liquid crystal. The shutter-filters work in sets of three, one passing the red part of the light source, a second driving the blue section of the light plus the last passing the green part of the light (RGB). These three types of light are classified as sub-pixels, and when viewed from even a close distance, 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 televisions is among their most evident weaknesses. It is seen that even the most costly and high class LCD displays possess a meager maximum aspect ratio of 1600:1, this is because of light having the ability to pass through to the liquid crystal display even once the television is in it's turned off position. This demonstrates exactly how exact this particular technology is.

Light Emitting Diode (LED) technology is definitely the obvious successor to LCD; yet, as powerful as the LCD successor, LED, is, even it is being expanded upon already with Organic Light Emitting Diode (OLED) technology. This system consists of filling the rear panel with RGB LEDs followed by incorporating a rim of White LEDs around the border, that act in unison through a diffusion panel to light the TV screen evenly and controllably.

So why might you choose an LED TV?

LED televisions are the lightest and slimmest TVs that you can buy because the Light Emitting Diodes used to fabricate them are also the most compact available commercial light sources used to build televisions. A number of LED TVs can be as thin as only a few millimeters. In addition to this, the fashion for home design right now, as you may well realize, is the simplistic, White, Glass, Strong Colors and Piano-finish Black look, which makes these modern, thin and unique televisions great for family homes in this day in age.

Furthermore, LCD televisions include major limitations relating to viewing angle and glare, which often can particularly be a issue in considerable open plan rooms. LED TVs combat this completely by incorporating the LED technology with dense, high quality glass and anti-glare modern technology that minimizes this tremendously, allowing for a substantially superior viewing angle.

Green seems to be the word of the year, and for good rationale too! The polar ice caps are reduing and it is the duty of each industry to reduce the quantity of energy and therefore fossil fuels their products and services are engineered to consume. LED TVs were undoubtedly fashioned with this in mind and therefore are capable of exhaling a better and even more stunning image 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.
