LCD Versus LED TVs: What is the Difference?

Buying a new TV has become a bit of a fine science- there are so many new terms to contend with that you may not exactly be sure what you’re buying into when you read the spec sheet of an LCD Flat Panel HDTV with 240Hz and 1080p resolution.

To give you a hand with what technology will suit your TV habits the most, Sony has come up with a rather helpful infographic to outline some basic differences.

Basically, if you’re wondering what the whole deal is with LCD and LED TVs, they’re not actually two different formats. Instead LED TVs are a member of the LCD family.

The display screen on a LED is a liquid crystal display, which is the same as it is on any other LCD TV. The main difference between the two lies with different backlighting techniques which has the ability to change the picture quality.

Traditional LCDs have used some form of fluorescent lighting such as tubes or more advanced flat arrays of lights. LED TVs use Light Emitting Diodes to light the LCD panel, so instead of standard tubes, the screen is lit up by thousands of small bulbs (or LEDs).

The benefit of all of these little bulbs working in tandem is that the screen can be lit in certain places whilst black areas receive no light, which produces a higher contrast and more noticeable detail in very dark and very light scenes on the TV. Basically it makes “Bear Grylls Does a Cavernous Area of Patagonia” that bit more nail biting.

By contrast (ha ha), traditional LCD televisions always have their backlight on, so must block the light to create black or dark areas on the screen.

I could continue to wax lyrically on TV lighting, but a picture speaks a thousand words, so check out the infographic below for a more digestible version of all of the above!

I love shiny things with flashing lights except furbys.
