1. OLED Siu Yuen Steven Donoso 5-7-14
Abstract:
An OLED is not just an LED that uses organic material, it is superior to LED in several ways. To begin with it is lighter, thinner, brighter, and has lower power consumption. The major drawbacks right now are the cost of manufacturing and lifespan of the device. However, in the near future these problems will be resolved.

3. History of OLED

4. History of OLED

5. Current Event

6. How it Works

7. Manufacturing Processes
Dimensions
Red (625 nm) and green (530 nm) diodes, and blue diodes (430 nm).
Lifespan
From 40K-100K hrs.
(14K for blue light). 7

8. Manufacturing Processes
Vacuum thermal evaporation (VTE)
Uses vacuum to heat up and evaporate small organic molecular materials and have it condense into film on a cool substrate.  
Organic vapor phase deposition (OVPD)
Low pressure, hot-walled reactor chamber using carrier gas to carry the evaporated organic material to a cool substrate to condense into film.
Inkjet printing
Spray long chained organic polymer materials as film on the substrate.
Spin-Casting
Liquid organic material placed on a centrifuge and as it spins it covers the whole substrate.

9. Materials Conducting polymers Polyaniline (PANI:PSS)
Polyethylenedioxythiophene (PDOT:PSS)
Emissive polymers
Polyphenylenevinylene (R-PPV)
Polyfluorene (PF)

10. Displays: OLED vs. LCD/LED
Advantages of OLED
Lower power usage
Faster refresh rate and better contrast
Brighter
Better durability
Simple design
Lighter weight
New screen types
Viewing angle

11. Displays: OLED vs. LCD/LED
Disadvantages of OLED
Costs
Life expectancy
Operation under bright light
Size limit

12. Lighting: OLED vs. Bulbs
Advantages of OLED
Thinner and lightweight
Lower power consumption
Can be used on transparent or reflective surface (mirror or window)
Cooler to the touch
Dimmable
No mercury
Flexible and can be
cut into any shape

13. Lighting: OLED vs. Bulbs
Disadvantages
High cost of materials
Lifespan is too short to make it cost effective

14. Future Applications Lighting Display Illuminating wallpaper
Flat panel lighting can fit
anywhere i.e. home, office,
and transportation
Luminescent window glass
Display
Head-up display (HUD)
Laptop monitor
Residential video wall
The rear lighting is provided by OLEDs for
the first time on a BMW.

15. Conclusion
OLED is a very appealing technology since it has good energy efficiency, many different uses, and no harmful materials toward humans. Although there are still some problems with this technology like the manufacturing costs and its lifespan. However, within a decade or so most if not all of these problems would be solved.

17. 5 Key Concepts Blue OLED burn out the fastest.
Polymer based OLED can be manufactured with an inkjet printer.
OLED is brighter because it’s not encased in glass which would absorb light.
Substrate doesn’t matter because it’s an emissive device.
Uses multiple layers to produce different colors.
