LED-backlit LCD from eyevis

This advantage of LED backlighting results in a provision of a wider colour gamut compared to CCFL backlit LCD s. LED's cover a broader range of red and greens (up to 114% of the NTSC standards):, the full area of the RGB natural colour space. Being able to display a more extensive range of colours means the attribute of colours is more natural or lifelike as they are closer to the human eye's colour perception range. More significantly is where that increased range is - in the areas of greens and reds, which really should make an impact on how accurately and vividly images are rendered on screen. This is of key importance for a colour-critical workflow situation. The LEDs also emit a more uniform light and degrade less quickly than CCFL backlight, which results in a more stable brightness over the lifetime.
LEDs have other advantages too. There's virtually no warm up time required, so you don't have to wait for your monitor to stabilise to get correct colours. Next, they are more eco- friendly, in that they don't contain mercury. Thirdly, they're more robust as they're much less susceptible to sudden failure or burnout. They can fade over time, but even with regular use you're looking at many years of benefiting from your LED-backlit screen.
The LCD LED backlight has a low power consumption. This is important for applications where the electrical power consumption has to be monitored, and you can save a lot of money from this LCD's low voltage requirement. Although it has smaller power requirement, it is still efficient in delivering quality display outputs. An LED-backlit display can consume up to 45% less power than CCFL bulbs.
