All of us are aware of the gradual evolution of televisions from the chunky black and white screens to smarter and sleek flat panel displays. With continuous improvement as the motto, the designing engineers are still pondering hard to come up with a better television that features all possible features. Wireless televisions and internet televisions were our there in our wildest dreams; now its realised and all thanks to the never ending improvement in the technology. LED televisions were conceptualised as a result of the energy war going on in the display industry. All major players in the display-making are highly competent and the subject for this competition keeps changing according to the current market trend.

Manufacturing efficient colour televisions were considered as the greatest challenge once upon a time; Gone are those days and presently stiff competition between the manufacturers is for coming up with energy saving televisions. Preserving the nature and mother earth is the need of the hour, and many efficient gadgets like plasma television are being thrown out of the market with its high energy requirement. Here comes a green way to enjoy life-like pictures and realistic motion images; LED Televisions. Samsung is the pioneer in LED Televisions, and has already released many LED models in the market. Many other experimental prototypes are yet to come. Now let us go skin deep into the vast LED technology!

In LED Technology, numerous small LEDs are used to create images, while in conventional LCD displays fluorescent lamp backlight is used. LED technology is also used in laptop screens, and is proven to be energy efficient and competent in rendering good video performance. The advantages of LED Technology includes low power requirement, better picture clarity and more precise control over tonal range and contrast of the images. In standard LCD television, a single tube is used to produce backlight system (CCFL). Hence controlling individual pixels for producing higher picture contrast is not possible in the case of fluorescent lamp backlight system. In the case of LED backlight system, numerous small LED bulbs are used to create image. These LEDs can be switched on or off according to the intensity of colour needed in that particular image, which inturn helps to augment the picture clarity, contrast and colour reproduction of the television dramatically.

The LED technology is much greener compared to the other display technologies. It needs absolutely zero mercury for manufacturing a  LED television. Mercury is quite hazardous to the environment and is capable of causing ecological jeopardies when used in bulk. Lighting consistency is yet another advantage  of this television. 45% more wider colour gamut can be offered by the usage of RGB LEDs for creating images. Wider colour gamut ensures the better efficiency of the display to reproduce colour tones. LED Televisions are shock resistant and sturdy, yet wafer thin that adds beauty to the living space as a much adorable piece of art. The life span of the display is expected to be higher in the case of LED displays compared to the displays of other prevailing technologies.

The energy demand of these screens are quite low, and one can save 40% of power compared to a normal LCD television. Innovations are made in the LED backlight system too. Initially the LED screens made use of the edge lit technique in which the LED bulbs are placed near the frame to render good images. However the new direct lit technique has emerged with the help of white LEDs to rectify the side-effects of edge lit LED displays. In the case of edge lit LED displays, the frame will be heated during the prolonged usage of television. With the usage of direct-lit technique this issue is eliminated considerably. LED backlight system made light weight wafer thin displays a reality, and is perfect for wall mounting. Though these displays throws a good deal with enhanced black levels, boosted contrast, enriched colour tones, better clarity and high energy efficiency, it is indeed pricey.
