  2. What is OLED? An Organic Light-emitting Diode (OLED) is a light emitting diode (LED) that is made of semiconducting organic polymers. Organic polymers are plastic electrons that are created from semiconductors Thinner Flexible Lighter

  3. New Technology Organic Light-emitting Diode Light Emitting Diode

  4. Organic Light-emitting Diode Cathode is an electrode that allows electric current to flow through Emissive Layer is a color filter of pixels made up of Polymers Conductive Layer is design to transport electrons Anode removes electrons from the Conductive layer Substrate is the plastic film of the OLED

  5. How OLED’s work? • Electric Current flows to the OLED. • An electrical current flows from the cathode to the anode through the organic layers. • The cathode gives electrons to the emissive layer of organic molecules. • The anode removes electrons from the conductive layer of organic molecules. • At the boundary between the emissive and the conductive layers, electrons find electron holes. • When an electron finds an electron hole, the electron fills the hole. • When this happens, the electron gives up energy in the form of a photon of light • The OLED emits light. • The color of the light depends on the type of organic molecule in the emissive layer. Manufacturers place several types of organic films on the same OLED to make color displays. • The intensity or brightness of the light depends on the amount of electrical current applied: the more current, the brighter the light.
