How is it possible for a TV to know what colors to use?
When talking about lcd vs led television it’s important to understand that pure LCD TVs have use a fluorescent tube for lighting. That means that the tube is producing a white light in the back of the tv. Ever stand over your TV and look down into the tv and see only a white light. That is the fluorescent backlighting.
LCD vs LED Television – Backlighting
In a LCD TV with LED backlighting. Instead of the fluorescent tube glowing white you have a panel of LED light, similar in shape to a string of Christmas lights, in the back of the tv. Again each LED light glows a bright white.
Now every single pixel in your TV screen is covered by a red/blue/green filter in the back. YES each and ever pixel. And just like your christmas lights depending on the color of the bulb / or filter used that is the light the LED light or Fluorescent light will display. Lcd vs led television debate is largely about the backlighting and the voltage being used in that pixel will trigger the right filter and the backlighting will refresh much faster than a standard lcd tv.
