Imagining you having a…
high-definition TV
80 inch wide1/4 inch thick
consumes less power
can be rolled up
What is OLED…?
O L E D
rganicightmittingiode
http://pt.wikipedia.org/wiki/OLED
OLED's are solid-state devices
!
composed of thin films of organic molecules
that create light with
the application of electricity

The advantages…
More crisper displays
More brighter
use less power than LED's or LCD’s
wider viewing angle
more FASTER than LED
LOWER manufacturing costs
LCD - Liquid Crystal Display

About the layers…?
Injects electrons when a current flows through
the device.

Cathode
It is made of organic plastic molecules that transport
electrons from the cathode. !
This is where light is made.
http://electronics.howstuffworks.com/oled.htm
Emissive
It is made of organic plastic molecules that transport "holes" from the anode.
http://electronics.howstuffworks.com/oled.htm
Conducting
Removes electrons when a current flows.

Anode
100 to 500NANOMETERS
thick
about 200 timessmaller than
a human hair
Made of clear plastic, glass, metal foil, the substrate
supports the OLED.

Substrate
The biggest part of manufacturing OLED's is applying the organic layers to the substrate.
How it works…?
Device containing the OLED applies a voltage across the OLED. !!

There are a lot of types…
Passive-matrix OLED (POLED) ! Active-matrix OLED (AMOLED) ! Transparent OLED (TOLED) ! Top-emitting OLED (TEOLED) ! Foldable OLED (FOLED) ! White OLED (WOLED)
Each type has different uses

Foldable OLED (FOLED)5
It is made of very flexible metallic foils or plastics ou flexible glass.
Foldable OLED's
They are very lightweight and durable.
