Encapsulation Types
- Encapsulation is classified into Can, TFE, and Hybrid methods
- Any method of encapsulation can be applied to brigid OLED for mobile devices
- TFE and Hybrid methods are applied to flexible OLED for mobile devices
- Only the hybrid method is applied to OLED for large-surface TVs
Hybrid Method
- Combination of advantages of the Can and TFE methods
- Polymers bind passivation film with a coverplate having a gas barrier property, and passivation film with a coverplate
- The Dam & Fill method uses a solution-type adhesive polymer and the Film Laminating method processes polymers into film
- The solution-type polymers are applied via screen printing or ink-jet printing while a rolllaminator is used for the Film Laminating method
- The passivation method can reduce costs because of fewer processes compared to the TFE method
- Top emission AMOLED panel can be manufactured if transparent polymers are used
