A Closer Look at
LED TVs deliver:
A slimmer, stylish profile
A better, brighter picture that excel sunder all lighting conditions
Greater energy efficiency and mercury-free production
The Basics
Before we talk about the advantages of LED TVs, there are a few basic facts we need to cover. The first thing to know is that what
we call LED TVs are simply a specific type of LCD TV. All LCD TVs use a liquid crystal display panel that is lit up (from behind) by
a separate light source. That’s where the newer technology of LED comes in. LED stands for “light-emitting diodes,” which serve
as the light source for LED TVs. Standard (non-LED) LCD TVs are lit by older-technology fluorescent lamps, which are bulkier, less
energy-efficient and usually produce an inferior picture.
The Two Basic Types of LED TVs
The benefits of LED TVs compared to standard LCD TVs differ depending on which of the two basic types of LED TVs we’re
talking about: backlit or edge-lit. Backlit LED TVs are lit by many LEDs placed all throughout the rear of the LCD panel, whereas
edge-lit LED TVs are lit by LEDs placed only around the edge of the panel. While both types maintain advantages over standard
LCD TVs, they each particularly excel in certain areas.
Edge-Lit LED TVs have a particularly strong advantage over standard LCD TVs in terms of
size — they can be much thinner. Some are less than 1.5 inches deep. This gives them a
beautifully slim, stylish profile and a much lighter weight — making them easier to mount
on a wall or move around (for easier cleaning or repositioning). They’re also considerably
more energy-efficient, so they save even more money on energy bills. Edge-lit LED TVs
can also offer many of the picture quality advantages of backlit LED TVs, including deeper
blacks and a brighter, better picture.

Backlit LED TVs have two main advantages over standard LCD TVs when it comes to
picture quality: they can produce deeper blacks and are especially good at creating more
vivid, accurate colors. An array of LEDs placed all throughout the back of the display panel
enables deeper blacks by allowing for more precise, localized control over the dimness
and brightness of specific areas of the screen. This is what’s generally referred to as “local
dimming.” And because LEDs are brighter, they can simultaneously produce brighter,
more vivid colors. These two capabilities combine to give these TVs a higher “contrast
ratio” — essentially the spread between the darkest darks and the brightest brights.
And while backlit LED TVs are not quite as energy-efficient or slim as their edge-lit
counterparts, they beat out standard LCD TVs on both scores.
