Organic Light Emitting Diodes (OLED) have high efficiency, low power consumption and wide color gamut which makes them an excellent choice for solid state lights (SSL) and displays. OLED displays are the first choice in high end portable electronic display and OLED SSL are making inroads into commercial lighting. High production cost due to manufacturing limitations of a crucible based system is one of the main reasons why OLEDs are not mainstream technology. The objective of this thesis is to demonstrate OLEDs fabricated by Kodak Vapor Injection Source (KVIS). KVIS is an on demand flash vaporization system, where the rate of deposition is governed by the amount of material fed rather than the crucible temperature.
Conventionally, OLED fabrication is done by vacuum thermal evaporation, where organic materials are heated in a crucible and the rate of deposition is a function of the temperature of the crucible. Organic materials are temperature sensitive and decompose when heated for extended durations at their vaporization temperature. This results in poor device performance and material wastage. The KVIS system was designed to overcome these problems. In the first part of the thesis an overview of the KVIS system is presented. Then we report green OLED devices fabricated using KVIS. The process control variables for the green devices were optimized to match the KVIS fabricated OLEDs characteristics to that of the reference devices. Finally, the single source co-deposition capabilities of KVIS are demonstrated and blue OLED devices are fabricated.
