Liquid Crystal Displays (LCDs):

These devices use back lighting systems which accounts for about half of the power needed, which is one reason why they require so much power.  These are nonorganic, nonemissive light devices, they do not produce any light, instead they simply block out light that comes from a external back light source unlike the OLEDs which create their own light.<>

Cathode Ray Tubes (CRTs):

These displays are made by using electron tubes. The electrons are accelerated by high-voltage anodes, formed into a beam by focusing electrodes and projecting them. These electrons beams leave a bright spot wherever it strikes the phosphor screen.

More Advantages of OLEDs:
high luminous effciency
high contrast
fast response time
wide temperature operstion range
potential of flexible substrate
       this opens the door to new applications such as roll-up displays or displayed embedded in clothing
lighter weight
easier to produce and can be made to larger sizes



Disadvantages of OLEDs:

limited lifetime of devices
       red and green OLED elements last well over 20,000 hours (avgerage: 10,000-40,000 hours)
       blue OLED elements last only about 1,000 hours
manufacturing  processes are expensive right now
water easily damages OLEDs
