The new generation of laptop screens offers you the choice of switching to an LED screen. Initially this can sound confusing and exciting until you see the price tag. So what’s all the fuss about LED?
The term LED actually refers to Light Emitting Diode and is a reference to the backlighting that is used in new laptops. The prevalent method of backlighting is Cold Cathode Fluorescent Lamps or CCFL. Both methods use LCDs in front but the benefits of LED are far superior.
In terms of power consumption, LED are great because they use up to 30 % less power than the CCFL screens. In terms of a laptop, this is a huge saving as the battery will last longer. Since you will charge the laptop less frequently, this also means that you save on your energy bill.
LED backed screens also give brighter and richer colors. Color accuracy and contrast is also improved. However, since LEDs adjust brightness levels automatically based on ambient lighting levels, these features may be less evident at times.
If you plan to use your laptop for a few years then LEDs are a good bet too. Over time CCFL screens start dimming and the output does not look as it once did. LED screens last longer and do not diminish over time. They also are lighter so the overall laptop weight goes down too.
As you can see, LED technology is actually the right way to go. The only thing stopping it from taking over the market is the current high cost of manufacturing. But if you consider the long term benefits that this technology offers, then the extra $100 or so you spend getting it, is truly justified.
