Edge-lit Vs Backlit What Is The Real Difference

Many people are dying to have those lovely LED TVs hanging on their walls. Little did they know that there are different types of LEDs. The two types are backlit and edge-lit TVs. They have the same principles; the only difference is the way the backlight is placed along the LCD panel.

Backlit, or sometimes-called full-array, is the type of LEDs wherein the LEDs are scattered at the back of the LCD panel. This type is capable of local dimming wherein the LEDs are switched on and off independently to produce deep darkness that plasma TVs give and high brightness that LCD TVs deliver. In this way, high and dynamic contrast is achieved giving a real life image. The property of the diodes is very useful in this technology since they are electrical semiconductors that can rapidly react when they are switched on and off. This is the characteristic that LEDs possess in which other HDTVs lack.

Edge-lit is the type of television in which the LEDs are placed along the sides of the panel. This is the reason why LED TVs can be as slim as one inch because the panels don't have to be directly at the back. This gives a very sleek exterior which can be very stylish that many people will love. The TVs with edge-lit are also very light making them easy to hang on the walls. Nowadays, edge-lit TVs are also capable of local dimming to deliver a higher contrast ratio as compared to the old designs.

The introduction of LED TVs in the market raised many questions regarding the technology used and the benefits of using that kind of high definition television. Many people don't understand how the new HDTV works and how they can benefit from it. Due to this fact, many people don't appreciate the new technology and they don't even bother to know the important facts regarding these TVs.

LED TVs are LCD TVs that use LEDs or light-emitting diodes as the backlight instead of the cold cathode fluorescent lamps or CCFL. LEDs are smaller than the fluorescent panels making TVs more power efficient. There are two varieties of LEDs: full array or backlit and edge-lit. Backlit TVs use many LED segments that are placed at the back of the LCD panel. Each LED can be turned on and off individually to produce high and dynamic contrast ratios and very clear images. This local dimming can produce deep blacks and high brightness so users can enjoy real high definition that LCD TV users can't enjoy.

Edge-lit, on the other hand, is the type of backlighting wherein the LEDs are situated along the edges of the panel. The light is dispersed and guided to the center of the screen making the black levels not as deep as that of the backlit. The benefit of having an edge-lit TV is that it has lighter weight because the panels used are thinner and they are only placed at the sides. This type of LED TV is also slimmer as compared to the backlit TV giving a very sleek exterior.
