LED vs LCD TV

LED vs LCD

LED is an acronym that stands for "Light Emitting Diode".
LCD is an acronym that stands for "Liquid Crystal Display".

What is LED vs LCD TV

An LCD TV is a television that uses LCD technology to produce the image and cold cathode fluorescent (CCFL) backlighting.  LCD requires backlighting to produce a display since liquid crystal does not produce light by itself.  So called LCD TV's using the CCFL backlighting are rapidly being replaced by LED TV's that are coming down in price and produce higher image quality.

An LED TV also uses LCD technology to produce the image, but use LED instead of CCFL for the backlighting.  The term LED TV is misleading, since LED TV does not actually use LED technology to produce the image.

Some LED TV's have a grid of LED's for backlighting behind the entire image area.  This allows a lot of control over making areas of the image darker and lighter as needed to produce the best image.  Some LED TV's have LED's around the edge of the TV and not behind the image area.  This technique is used to produce extremely thin TV panels.

With price reduction of LED backlighting technology, you can now get a 32 inch full High Definition LED TV with 60 Hz refresh rate for just over $300:
