Next Generation TVs

By Feni Mecc


Since death of Cathode Ray Tube (CRT) tvs in 2007, probably the most dominant fabrication technique for TVs has been Liquid Crystal Display (LCD). LCD technology function by layering the display with a layer of liquid crystal followed by firing white light via small filter-shutters at it. The white light derives from a supply of cold cathode fluorescent lamps in the back of the television and is altered color by precise calibrations of the shutter-filters. The shutter-filters work in groups of three, one passing the red element of the light, one more driving the blue aspect 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 looked at from even a close vicinity, merge together into one color, depending on 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 most costly and high class LCD displays have a measly maximum aspect ratio of 1600:1, this is due to light being able to pass through to the liquid crystal screen even when the television is in it's turned off position. This demonstrates just how accurate this sort of technology is.

Light Emitting Diode (LED) technology is the obvious successor to LCD; nevertheless, as effective as the LCD successor, LED, is, even it is being expanded upon already with Organic Light Emitting Diode (OLED) technology. This feature is comprised of filling the rear panel with RGB LEDs followed by adding a rim of White LEDs around the border, that act in unison by way of a diffusion panel to light the screen uniformly and controllably.

So why might you desire an LED TV?

LED televisions are the lightest and slimmest TVs on the market since the Light Emitting Diodes used to fabricate them are also the smallest readily available commercial light sources used to construct televisions. Some LED TVs can be as thin as just a couple millimeters. Alongside this, the style for interior design right now, as you may well know, is the simplistic, White, Glass, Strong Colors and Piano-finish Black look, which makes these sleek, thin and exceptional televisions perfect for houses in this day in age.

Furthermore, LCD televisions come with major limitations in relation to viewing angle and glare, which often can especially be a issue in substantial open plan rooms. Alternatively, LED TVs combine the LED technology with dense, high quality glass and anti-glare technology that minimizes this tremendously, allowing for a much greater viewing angle.

Green appears to be the word of the year, and for good rationale too! The polar ice caps are melting and it is the duty of each business to minimize the level of electrical power and consequently non-renewable fuels their products and services are engineered to consume. LED TVs were most definitely designed with this in mind and are capable of exhaling a much brighter and even more dazzling picture than a LCD TV and with a fraction of the power.

The production of 3D technologies have disrupted the television marketplace dramatically. The notion of having wildlife, weather effects and actors/actresses appearing out of the TV into people's homes is driving the planet nuts. Should you also enjoy the thought of this advanced technology then a 3D LED HDTV is the ideal solution, providing a streamlined design, lower power consumption, a vibrant and powerful High-definition image and of course, the best 3D technology obtainable.

LED TVs are very dynamic in relation to size and can range from small-scale 21.5 inch computer monitors, all the way up to massive 70 inch screens. Yet, personally I believe that the best television for any common sized house is a Samsung 55 inch LED TV.
