As I mentioned previously, the major difference between an LCD and an LED television is the kind of backlighting it utilizes to present its picture. An LCD utilizes what is referred to as a cold cathode fluorescent lamp (ccfl) for background lighting. The fluorescent lamps use a plastic shield before the censors to smoothly distribute the light. LED stands for light emitting diode, which are comparable to the lights you put on a Christmas tree, only quite smaller. This is where the discussion between LCD vs. LED starts to unravel ljusskyltar when referring to the quality of the images. The LEDs are set in rows and contrary to the LCD, it doesn't function using a plastic shield to display its lighting. The brand new LED models are equipped with precisely placed censors in the LED as well as the crystal display to monitor the picture being conveyed. These sensors are utilized to analyze the 1's and 0's data that is being emitted and modifies the color being displayed pixel by pixel, so it's capable of using its light more effectively. Think of it like flip sunglasses. These sensors function in the similar manner that flip glasses do, only utilizing several different types of shades. Utilizing this kind of technology on an LED HDTV, you are able to view much richer blacks, sharper image color and a more luminous picture. This is the main reason an LED can display for you a more vibrant picture. So when it comes to the LCD vs. LED debate, what you're actually referring to is LED back lighting vs. fluorescent back lighting.
