LED Technology Background

By Domius Webb


Cathode Ray Tube systems died out in 2007, when it appeared to be superseded by Liquid Crystal Display (LCD) technology. LCD technology operate by layering the display with a sheet of liquid crystal followed by firing white light by means of small filter-shutters at it. The white light derives from a source of cold cathode fluorescent lamps at the rear of the TV and precise calibrations of the shutter-filters are used to establish the color of the light acquired by the liquid crystal. The shutter-filters operate in sets of three, one passing the red aspect of the light, another driving the blue aspect of the light plus the final transferring the green portion of the light (RGB). These three sources of light are known as sub-pixels, and when looked at from even a close distance, merge mutually into one color, dependant upon the mix ratios of each colored light let through, to create a pixel.

The aspect ratio of Liquid Crystal Display televisions is one of their most evident weaknesses. It can be seen that even the priciest and classy LCD displays have a measly maximum aspect ratio of 1600:1, this is because of light being able to pass through to the liquid crystal display even when the TV screen is in it's turned off position. This reveals exactly how exact this type of technology is.

Light Emitting Diode (LED) technology is definitely the distinct successor to LCD; nevertheless, as impressive as the LCD successor, LED, is, even it is currently 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 concurrently via a diffusion panel to light the monitor consistently and controllably.

So why might you prefer an LED TV?

LED televisions are the lightest and thinnest TVs that you can buy since the Light Emitting Diodes used to fabricate them are also the most compact available commercial light sources used to construct televisions. Some LED TVs are often as thin as just a few millimeters. Alongside this, the style for home design at the moment, as you may well know, is the simplistic, White, Glass, Bold Colors and Piano-finish Black look, which makes these sleek, slim and unique televisions excellent for houses in this day in age.

Furthermore, LCD televisions come with major limitations concerning viewing angle and glare, which often can especially be a issue in sizeable open plan rooms. On the other hand, LED TVs merge the LED technology with thick, top quality glass and anti-glare modern technology that minimizes this notably, allowing for a significantly 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 level of power and therefore non-renewable fuels their products are designed to consume. LED TVs were clearly fashioned with this under consideration and therefore are capable of exhaling a better and even more dazzling image than a LCD TV and with a small fraction of the energy.

Finally, the next popular trend across the world is 3D technology. The idea of having pets or animals, weather effects and actors/actresses emerging from the TV into people's homes is driving the world nuts. If you also like the very idea of this advanced technology then a 3D LED HDTV is the perfect choice, delivering a sleek design, lower power consumption, a vibrant and powerful High definition image and of course, the very best 3D technology out there.

With regards to size options, LED TVs can come in a variety of sizes, from small 20 inch monitors to great 70 inch screens. Nevertheless, personally I feel that the perfect television for any typical sized house is a Samsung 55 inch LED TV.
