LED and LCD monitors are based on the same basic technology for image display. But differ is back lighting used. While LCD monitors are use cold cathode fluorescent lamps for back lighting, LED monitors are use light emitting diodes. This is the Major Difference between LCD – LED.
Unlike CRT monitors that generate their own light through cathode ray incidence on fluorescent materials, LCD displays have to rely on external lighting as their display is created through manipulation of light passing through polarized liquid crystals. The back lighting affects picture quality substantially and light shed by LEDs offer superior picture quality compared to LCDs.
This is because LEDs offer much more gradation in intensity, giving a much truer color quality. These types of monitors offer a better dynamic contrast ratio too. So LED monitors are surely better choices.
There are two types of LED back lighting techniques used. One is RGB dynamic LED and the second thing is edge LED. The former type of back lighting uses LEDs placed behind the LCD TV or monitor screens, while the latter uses LEDs placed around the monitor rim, from where light is made to diffuse behind the screen. Since LEDs are placed around the rim on edge LED monitors, they can be a lot slimmer than conventional LCDs.
LED Vs LCD Monitor: Power Saving
LED monitors are a very recently introduced technology and they are preferred over LCD monitors because of the amazingly rich picture quality and comfort of viewing. One more advantage that LED monitors have over LCD ones is the power consumption factor. 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 also a lot softer on the eyes than 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 because mercury is not used in their production
