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

About the layers…?

Injects electrons when a current flows through

the device.

http://electronics.howstuffworks.com/oled.htm

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.
