Since the death of Cathode Ray Tube (CRT) television sets in 2007, probably the most prominent manufacturing method for TVs has been Liquid Crystal Display (LCD). LCD technology work by layering the display screen with a sheet of liquid crystal followed by shooting white light via small filter-shutters at it. The white light comes from a source of cold cathode fluorescent lamps at the rear of the TV and is changed color by highly accurate calibrations of the shutter-filters. The shutter-filters work in groups of three, one transferring the red section of the light source, one more passing the blue section of the light and the last passing the green part of the light (RGB). These three sources of light are classified as sub-pixels, and when considered from even a close vicinity, blend mutually into one color, dependant upon the mix proportions of each colored light let through, to form a pixel.
The aspect ratio of Liquid Crystal Display televisions is among their most blatant weaknesses. It can be seen that even the priciest and high class LCD displays have a meager maximum aspect ratio of 1600:1, this is as a result of light having the ability to pass through to the liquid crystal display even when the TV screen is in it’s turned off position. This shows exactly how accurate this particular technology is.
Light Emitting Diode (LED) technology reached the marketplace not too long ago and exploded consistently over the last couple of years with the release of Organic Light Emitting Diode (OLED) technology. This method is comprised of filling the rear panel with RGB LEDs followed by incorporating a rim of White LEDs around the border, that act concurrently by way of a diffusion panel to light the monitor consistently and controllably.
So why would you choose an LED TV?
The Light Emitting Diodes used in this innovative technology are some of the lightest and thinnest commercially produced light sources in the world and for that reason, the lightest and thinnest constructed televisions are LED TVs. Some LED TVs are often as thin as just a couple millimeters. In addition to this, the style for interior design presently, as you may well realize, is the simplistic, White, Glass, Bold Colors and Piano-finish Black look, that makes these sleek, thin and distinctive televisions perfect for houses in this day in age.
Moreover, LCD televisions have major limitations in relation to viewing angle and glare, which may especially be a problem in substantial open plan rooms. LED TVs combat this completely by incorporating the LED technology with dense, top quality glass and anti-glare technology that minimizes this notably, permitting a much superior viewing angle.
Being beneficial to the environment is definitely the thought on everyone’s mind, and for good reason too! The polar ice caps are fading and it is the duty of every enterprise to reduce the quantity of electrical power and therefore non-renewable fuels their products are designed to consume. LED TVs were most definitely designed with this under consideration and are capable of exhaling a better and even more stunning picture than a LCD TV and with a fraction of the power.
Finally, the next popular trend in the world is 3D technology. The notion of having pets or animals, weather effects and actors/actresses emerging from the television 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 ideal choice, delivering a sleek design, lower power consumption, a vibrant and powerful High definition image as well as, the best 3D technology out there.
LED TVs are extremely dynamic with regard to size and can vary from modest 21.5 inch computer monitors, all the way up to giant 70 inch displays. Even so, personally I feel that the perfect television for any typical sized house is a Samsung 55 inch LED TV.
