3 ways, each pixel is made up of 3 LED (Light Emitting Diode) each a different color, red, green, and blue, that is if you were asking in reference to a LED flat panel TV! !
LED Video light is a combination of LEDs in the form of a round shape to depict a bulb, in the form of square shape, and many different shapes. Nowadays, LED TVs are also coming into the world which is a television that uses LED as pixels.
Light-Emitting Diode =LED LED is not a kind of display, when we say LED tv is actually means LCD display with LED back lights.

many thing's such as TVs (standby light), laptops( such as the macbook's) , game consoles, or more technically a led par can (what some theatres use) Tommy
You can find them in light bulbs, flashlights and other forms of illumination. If you are looking for LED light bulbs, CREE, PHILIPS, LITENZ are the companies that manufacture LED light bulbs using their own LEDs.
Powering electronic devices such as TVs, computers, and phones. Heating elements in appliances like stoves, ovens, and hair dryers. Providing light through light bulbs and LED fixtures.
Basically ,LED stands for Light Emitting Diode and LCD stands for Liquid Crystal Display. LCD TV use fluorescent lights while LED TV use those light emitting diodes. The fluorescent lights in an LCD TV are always behind the screen. On an LED TV, the light emitting diodes can be placed either behind the screen or around its edges. In my opinion, LED TV is more efficient than LCD TV
LED, this is because a light emitting diode(LED) is a form of light that uses electricity and converts it into electromagnetic radiation -LEDs are therefore long lasting tech.
I don't know about LED TV but i know LED (Light Emitting Diodes) was invented in 1962 so most likely not too long after that.
LED Back-light gives a better contrast ratio as compared to LCD. The resulting image in case of LED is smoother, sharper, and vivid. The color reproduction is also far more superior. But Technology wise there isn't much of a difference. LED TV is just an LCD TV with LED Back-light
Liquid-crystal display televisions (lcd), Use a lot of Power. Light-emitting diode (led) is using Half the power. So buy led tv!
