Encapsulation method of OLED and a structure of OLED

摘要

The invention provides an encapsulation method of OLED and a structure of OLED, and the method comprises: step 1: providing a glass cover and an encapsulating substrate, and the glass cover comprising a display area and an edge area surrounding the display area; step 2: forming a layer of SiNx on the edge area of the glass cover; step 3: self-arranging a layer of hydrophobic monomer on the display area surface of the glass cover; step 4: coating a circle of glue frame around the display area on the glass cover; step 5: coating desiccant on the layer of hydrophobic monomer on the display area of the glass cover; step 6: attaching the glass cover correspondingly to the substrate in vacuum environment; step 7: illuminating by UV light to cure the glue frame to achieve the glass cover encapsulating the substrate.

1. An encapsulation method for OLED, comprising following steps:
step 1: providing a glass cover and an encapsulating substrate, and the glass cover comprising a display area and an edge area surrounding the display area; step 2: forming a layer of SiNX on the edge area of the glass cover to encircle the display area; step 3: self-arranging a layer of hydrophobic monomer on and in contact with a surface of the display area of the glass cover, wherein the surface of the display area is a hydrophilic surface, the layer of SiNX is configured for limiting the layer of hydrophobic monomer within the display area; step 4: coating a circle of UV curable glue frame around the display area of the glass cover and on the layer of SiNX such that the layer of SiNX is located between the UV curable glue frame and the glass cover; step 5: coating a liquid desiccant of non-polar on the layer of hydrophobic monomer on the display area of the glass cover whereby the liquid desiccant of non-polar being distributed evenly on the display area owing to hydrophobicity of the layer of hydrophobic monomer; step 6: attaching the glass cover correspondingly to the substrate; step 7: illuminating by UV light to cure the UV curable glue frame to achieve the glass cover encapsulating the substrate.
