Embodiment 1

[0051] According to the design and process of the invention, the hybrid packaging structure and steps of vacuum sputtering and photocuring resin are as follows:

[0052] According to the design and process of the invention, its packaging scheme is very simple and practical, and the following steps are adopted:

[0053] In the first step, the ready glass or high-barrier flexible substrate is prepared, and the surface can be cleaned. And put it into a vacuum drying oven to remove more than adsorbed water vapor and oxygen. Putting glass or high-barrier flexible substrates into organic electronic device equipment completes the preparation of organic device OLEDs.

[0054] The third step is to prepare 100nm LiF on the prepared OLED device, or Al 2 o 3 Film protective layer.

[0055] The fourth step is to transfer the sample into a nitrogen glove box with water and oxygen less than 1ppm at 20°C. Apply a layer of UV curable resin by spin coating, hang coating process, about 5-50...

Abstract

The invention discloses a mixed packaging structure and process for two ultrathin flexible organic electronic devices. A preparation process of mixing nano sputtering and organic curing resin is mainly utilized, a compact nano material with a high packaging effect is semi-injected into an organic material resin layer, and then photocuring is carried out to greatly improve the water and oxygen blocking capability of organic cured resin in the packaging process, so that the packaging efficiency, the packaging yield and the reliability of UV cured gluing resin are greatly improved while the packaging and curing of organic devices are ensured. The process can be applied to high-performance water and oxygen blocking packaging of various ultrathin and flexible organic electronic devices, and particularly can combine a nano-film layer with an organic photocuring numerical value to realize efficient packaging of the ultrathin organic electronic devices.
