Now, what is LED means? What is has to do with the latest innovation of televisions? LED means Light Emitting Diode. It is an electronic light source. It was actually invented back in 1920’s. At the early stage this light source only emitted low density red light. Now with the technology advancement, they are using the ultraviolet and infrared wave length to produce a very high density lighting source. This is how the latest generation of LED televisions can generates crystal clear pictures.
The advantages of using the (LED) Back Lighting display from the current (CCFL) Cold Cathode Florescent Lamp lighting display, the LED consumes less energy to operate. According to Samsung, their Led televisions consume about 40% less energy usage compare to the conventional lighting televisions. That is really a huge amount of energy reduction. It can fire up the screen much faster, last longer,smaller or thinner for the display and the most important part, the highest picture clarity of all.
The disadvantage of the LED back lighting technology are relatively a lot more expensive because it requires more precise current and heat management conmpare to the current CCFL lighting display.
