MANUFACTURING METHODS1. Spin coating process: In this a glass substrate is spinned at a fixed angular velocity on which a plastic solution is poured.2. Printer based Technique: LEPs can be patterned using a wide variety of printing techniques. The most advanced is ink jet printing with a resolution as high as 360 DPI.
ADVANTAGES Operates with 3.3volts only As active material is plastic cost is much less than CRT, LCD. Greater power efficiency than all other flat panel displays Life time of more than 30,000 hours Can be viewed at any angle Fast switching speed i.e. 1000 times faster than LCDs. Higher luminescence efficiency
LIMITATIONS Ageing of LEP Space charge effect
APPLICATIONS Multi or full color cell phone display HD Television display Light weight wrist watches Military applications Aircraft cockpit instrumentation
CONCLUSION LEP technology is now set to change the products we use to view the world
