Outgas-free organic film formation for OLED encapsulation devices |
| 초록 |
For realization flexible OLED display devices, encapsulation technology is a key technique for improving the yield and lifetime of a panel by shielding the device from oxygen and moisture. Currently the TFE method, which alternately stacks organic and inorganic membranes, has priority. In the TFE process, organic films are currently formed primarily by ink-jet printing. Most of the organic films produced by that techniques are made using photocurable polymers. However, the byproducts of the photoinitiator that remain after radical generation are slowly released in the form of gas in the formed film, and such outgassing is a major drawback to the durability. To solve this problem, we introduce photoinitiators that do not produce by-products. The photoinitiator is expected to be able to solve outgas fundamentally because it does not generate radicals and any byproducts, unlike ordinary initiators. |
