Advantages of LED over LCD TV:

Keep in mind that the LED HDTV’s currently available in the market are nothing but LCD TVs with LED-backlight. There are few major benefits for LED HDTV’s over traditional LCD televisions with CCFL lamps.

1. LED Edge-lit HDTVs are very thin:

The edge-lit LED HDTV models are way thin compared to LCD and Plasma TVs. For example the 32inch Samsung LED TV is just 1.17 inches thick.

2. Better Picture Quality:

Some LED HDTV models with dynamic RGB LED back lighting with local dimming can display truer blacks, whites at much higher dynamic contrast ratios. This can produce better quality motion graphics with right picture settings. But most of the edge-lit LED TV models doesn’t improve the picture quality at all.

3. Power Saving:
LED consumes less power compared to CCFL lamps and as a result the edge-lit LED HDTV consumes less power than regular LCD and Plasma televisions


The LCD television is a flat-panel television that utilizes the Liquid Crystal Display technology. The LCD TV has two layers of glass which are polarized and stuck together. One of these layers holds the liquid crystals. These liquid crystals allow the light to pass, or obstruct the light source, to deliver images on the LCD screen when the electric current flows through it.

The light source in LCD TV is a group of CCFL lamps (cold-cathode fluorescent lights) at the back of the screen. With the help of the fluorescent lamps, the pictures produced by the liquid crystals get viewable to the spectator.


The LED Televisions are actually a type of LCD TV. The LED televisions also make use of Liquid Crystal Display technology. The difference lies in their source of light, that is at the back of the screen. The LCD TV utilizes fluorescent lamps, and the LED TV uses Light Emitting Diodes (LED).

Types of LED TVs
There are mainly two types of LED TVs depending upon the system of light source. One is called the Edge lighting, and the second one is called Full-Array lighting.
