While there's contention as to whether LED TVs actually exist (they don't), the term has nevertheless gained popularity.
LED is not a new technology but a type of shorthand used to describe an LCD television that is lit by banks of light-emitting diodes (LEDs).
When describing this technology, there are two types of LED-lighting: direct or edge. Direct means the LEDs are behind the screen, while edge means the LEDs are along the side and directed across the screen by plastic guides.
Which is better? While edge-lit screens can be thinner, direct usually gives the best images as the LEDs can be turned off individually — leading to better blacks.
The following TVs are a mix of both technologies, but demonstrate the best LED-lit TVs available.
