Are you planning to get a new TV for this holidays? I am almost certain that you may want to buy a HD TV. However what type of high definition TV? There are so many types of high definition televisions in the market place one could easily get confused. In most stores you will find choices like LCD, Plasma and the new LED TV. How are they different and which TV is fitting for you? In this article let’s check the difference between LCD Vs LED TVs.
The LCD HDTV or Lquid Crystal Display TV is a flat-panel television that uses a Liquid Crystal Display technology. LCD television has 2 layers of glass that are polarized and stuck on each other. One of these layers holds the liquid crystals. These liquid crystals pass, or obstruct the light source, to produce pictures on the TV screen when the electric current passes through it.
The light source in LCD TV is a number of fluorescent lamps at the rear of the screen. With the help of the CCFL lamps, the images created by the liquid crystals become viewable to the spectator. An example of LCD TV with light emitting diodes backlight is Samsung LN40C630 LCD TV.
LED Televisions are in reality a specific type of LCD TV. LED TV’s also employ Liquid Crystal Display technology. The difference lies in their light source, which is at the back of the display screen. The LCD TV utilises fluorescent lamps, and the LED TV utilizes Light Emitting Diodes (LED). Example for LED TV: the Samsung LED TV series.
Types of LED TVs:
There are two different types of LED TVs depending on the placement of light source. One is referred to as Edge lighting, and the second one is called Full-Array lighting. With the Edge lighting, the group of light emitting diodes are placed on the outside edges of the display screen. On the other hand, in Full-Array lighting, there are numerous rows of light emitting diodes behind the entire area of the tv screen. They allow better control over brightness level and dimming, because the diodes can be switched on and off independently.
Advantages of LED over LCD TV
Is LED TV better than traditional LCD televisions? Actually you should enquire, is LCD TV with LED backlight better than LCD Televisions with CCFL backlight as the only differnece is the light source. There are few advantages of bringing home an LED TV.
Starting the LED Televisions generate somewhat better motion graphics because Light Emitting Diodes are able to create better balance in color intensity. LED Televisions also consume less power than the traditional fluorescent lamps.
