What is OLED…?
Organic
L ight
E mitting
Diode
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 brighter
More crisper displays
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…?
Cathode
Injects electrons when
a current flows through
the device.
http://electronics.howstuffworks.com/oled.htm
Emissive
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
Conducting
It is made of organic plastic
molecules that transport
"holes" from the anode.
http://electronics.howstuffworks.com/oled.htm
Anode
Removes electrons when
a current flows.

100 to 500
NANOMETERS
thick
about 200 times
smaller
than
a human hair
Substrate
Made of clear plastic, glass,
metal foil, the substrate
supports the OLED.
http://electronics.howstuffworks.com/oled.htm
The biggest part of
manufacturing OLED's
is applying the organic
layers to the substrate.
How it works…?
1
Device containing the OLED
applies a voltage across the
OLED.

layer.
There are a lot of types…
1 Passive-matrix OLED (POLED)
!
2 Active-matrix OLED (AMOLED)
!
3 Transparent OLED (TOLED)
!
4 Top-emitting OLED (TEOLED)
!
5 Foldable OLED (FOLED)
!
6 White OLED (WOLED)
Each type has different uses

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