Abstract
A display device and an adhesion method of 3D cover glass are provided. The display device includes a display panel, and a polarizer, a first OCA layer, a second OCA layer, and a 3D cover glass sequentially disposed on the display panel, where a stripping force between the 3D cover glass and the second OCA layer and a stripping force between the second OCA layer and the first OCA layer are the same, and both are greater than a stripping force between the first OCA layer and the polarizer.
Claims14
An adhesion method of a three-dimension (3D) cover glass, comprising:
- step S1, providing a display panel which is to be adhered with the 3D cover glass, wherein a polarizer is attached to the display panel, and a first optically clear adhesive (OCA) layer is formed on the polarizer;
- step S2, performing a viscosity enhancement treatment on a surface of the first OCA layer, wherein the surface is away from the polarizer;
- step S3, forming a second OCA layer on the first OCA layer, and performing the viscosity enhancement treatment on surfaces of the second OCA layer, wherein one of the surfaces is in contact with the first OCA layer and the other surface is away from the first OCA layer;
- and
- step S4, attaching the 3D cover glass on the second OCA layer.
A display device, comprising:
- a display panel which is cell-assembled;
- a polarizer disposed on a surface of the display panel;
- a first OCA layer formed on the polarizer;
- a second OCA layer formed on a surface of the first OCA layer;
- and
- a 3D cover glass disposed on the second OCA layer,
- wherein a stripping force between the 3D cover glass and the second OCA layer and a stripping force between the second OCA layer and the first OCA layer are substantially the same, and both are greater than a stripping force between the first OCA layer and the polarizer.
A display device, comprising:
- a display panel which is cell-assembled;

- a first OCA layer formed on the polarizer;
- a second OCA layer formed on a surface of the first OCA layer;
- and
- a 3D cover glass disposed on the second OCA layer,
- wherein a stripping force between the 3D cover glass and the second OCA layer and a stripping force between the second OCA layer and the first OCA layer are substantially the same, and both are greater than a stripping force between the first OCA layer and the polarizer, and a viscosity of the first OCA layer is less than a viscosity of the second OCA layer,
- wherein a surface of the first OCA layer in contact with the polarizer is substantially smooth.
