FIELD OF THE INVENTION:
This invention relates to a method of manufacturing an organic lighting device. More particularly this invention relates to a high throughput and high yield method of manufacturing an organic light emitting device (OLED).
BACKGROUND:
Organic light emitting devices (OLED) are increasingly becoming a popular technology for various applications including flat panel displays and lighting systems for illumination.
Organic light emitting devices are generally manufactured by employing various methods such as screen printing, dip coating, spray coating, doctored blade, spin coating, sputtering, evaporation etc on large sized panels involving panel by panel, roll to roll and other large form factor manufacturing processes. These large sized panels are later sliced to form organic light emitting devices of required product sizes. However, such large form factor manufacturing processes tend to increase defects and non-uniformities in the active layers of the organic light emitting devices. These defects lead to poor device performance and very low process yields for the organic light emitting devices. Further, slicing of the substrates results in loss of material as well as introduces additional process steps such as cleaning of debris which in turn reduces yield. This makes these devices highly expensive and non-competitive with other technologies. Furthermore, many of these manufacturing processes are not scalable leading to delays in faster commercialization for these devices.
In light of the above, there is a need of a method of manufacturing organic lighting device which overcomes the above mentioned problems and creates a process by which small form factor product sized substrate OLEDs can be manufactured with high throughput but largely devoid of problems mentioned above.
