Since death of Cathode Ray Tube (CRT) televisions in 2007, by far the most prominent fabrication method for TVs is Liquid Crystal Display (LCD). LCD technology work by layering the display screen with a layer of liquid crystal and then firing white light via 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 specific calibrations of the shutter-filters. The shutter-filters work in sets of three, one transferring the red part of the light source, a second passing the blue part of the light and the last passing the green portion of the light (RGB). These three sources of light are called sub-pixels, and when perceived from a close distance, blend mutually into one color, dependent upon the mix ratios of each colored light let through, to create a pixel.
On the other hand, LCD display screens do definitely have their own weaknesses. A good example of this is that although LCD televisions are in their turned off state, they still allow a small amount of light to slide through the shutters, which means their contrast ratio can never be greater than 1600:1
Light Emitting Diode (LED) technology approached the marketplace recently and erupted consistently over the past couple of years with the introduction of Organic Light Emitting Diode (OLED) systems. This method is comprised of filling the rear panel with RGB LEDs and then adding a rim of White LEDs around the edge, that act concurrently by way of a diffusion panel to light the display evenly.
So why might you choose an LED TV?
LED televisions are the lightest and slimmest TVs available on the market simply because the Light Emitting Diodes used to fabricate them are also the smallest obtainable commercial light sources used to manufacture televisions. Some LED TVs can be as slim as only a few millimeters. In addition to this, the fashion for home design right now, as you may well realize, is a simplistic, White, Glass, Strong Colors and Piano-finish Black look, making these modern, slim and distinctive televisions excellent for homes in this day in age.
Moreover, LCD televisions have major limitations relating to viewing angle and glare, which can especially be a issue in large open plan rooms. LED TVs combat this completely by combining the LED technology with dense, top quality glass and anti-glare modern technology that reduces this notably, permitting a much greater viewing angle.
Green appears to be the phrase of the year, and for good reason too! The polar ice caps are melting and it is the job of each enterprise to lessen the quantity of energy and consequently fossil fuels their products are engineered to consume. LED TVs were undeniably designed with this under consideration and are capable of exhaling a brighter and even more vibrant image than a LCD TV and with a small fraction of the energy.
Lastly, the next big thing across the world is 3D technology. The perception of having wildlife, weather effects and actors/actresses appearing out of the TV into people’s homes is driving the planet crazy. If you also enjoy the very idea of this futuristic technology then a 3D LED HDTV is the perfect choice, delivering a sleek design, reduced power consumption, a bright and strong High definition image and of course, the best 3D technology out there.
LED TVs are incredibly dynamic in relation to size and can vary from small-scale 21.5 inch monitors, all the way up to enormous 70 inch displays. However, personally I feel that the perfect television for any common sized home is a
