LED and pc LCD monitors are based on the same basic technology for image display, but differ in the kind of backlighting used. While these monitors use cold cathode fluorescent lamps for backlighting, LCD uses light emitting diodes. This is the main difference between the two technologies.

Unlike CRT monitors, LCD displays have to rely on external lighting, as their display is created through manipulation of light, passing through polarized liquid crystals. The backlighting affects picture quality and light shed by LEDs offers superior picture quality.

LEDs offer much more gradation in intensity and a larger light wavelength spectrum, giving a truer color quality. These monitors offer a better dynamic contrast ratio too. LED monitors provide vivid and more lifelike colors, with better gradation.

There are two types of LED backlighting techniques. One is RGB dynamic LED and the other one is edge LED. Since LEDs are placed around the rim on edge LED monitors, they can be a lot slimmer than conventional LCD monitor tvs.

LED monitors cure one of the basic problems with LCD TVs, which is the inability to display true black colors. They can produce true black hues, by switching off LEDs entirely, increasing the blackness quotient of black colors, providing better contrast in the process.

LED monitors are a new technology and they are preferred over LCD monitors. Another advantage that LED monitors have over LCD ones is the power consumption. LED monitors require a lot less power to operate than cold cathode fluorescent lamps. This property can be attributed to the inherently low energy needs of an LED.

LED monitors are a lot softer on the eyes than computer LCD monitors which make them popular choices for people who work for long hours on their desktop computers. Their power consumption is as much as 40% lesser than conventional LCD monitors. They are also a lot more eco-friendly, for mercury is not used in their production. LEDs last longer than cold cathode fluorescent lamps, with little reduction in their power output over time, which makes these monitors long-lasting.
