  1. 1. under the guidance of Mrs. Shobha p cdept of ece, AIT BANGALORE Presented by Hemant Kumar Sharma ( 1AT08EC043)
  2. 2. What is an OLED? OLED - Organic Light Emitting Diode An OLED is an electronic device made by placing aseries of organic thin films between two conductors. Whenelectrical current is applied, a bright light is emitted..
  3. 3. Architecture of OLEDs
  4. 4. How OLEDs Emit Light *The battery or power supply of the device containing the OLED applies a voltage across the OLED. *An electrical current flows from the cathode to the anode through the organic layers.(an electrical current is a flow of electrons) *At the boundary between the emissive and the conductive layers, electrons find electron holes. *The OLED emits light
  5. 5. Types of OLEDs Passive-matrix oled Active-matrix oled Transparent oled Top-emitting oled Flexible oled
  6. 6. Passive-Matrix
  7. 7. Active-Matrix
  8. 8. Transparent
  9. 9. Top-Emitting
  10. 10. Flexible
  11. 11. Applications of OLEDs• Televisions• Cell Phone screens• Wrist Watch• Computer Screens• Digital Camera• Portable Device displays
  12. 12. Advantages of OLEDs Thinner, lighter and more flexible Brighter Consume much less power Large field of view Faster response Less Expensive Better contrast ratio
  13. 13. Disadvantages of OLEDs OLED seems to be the perfect technology for all types of displays, but it also has some problems:• Lifetime• Manufacturing• Water
  14. 14. Future Uses for OLED GPS system OLED – in future cars Curved OLED displays, placed on non-flat surfaces And many more we cannot even imagine todayScroll Laptop • Nokia concept OLED Laptop
