Abstract
The present application provides a touch panel, a touch display device, and a fabrication method thereof. The touch panel includes an encapsulation cover and a touch substrate disposed oppositely; and a first sealant disposed between the encapsulation cover and the touch substrate, wherein the encapsulation cover, the touch substrate, and the first sealant are enclosed to form a first cavity, and the first cavity is filled with a transparent filling layer.
Claims13
A touch panel, comprising:
- an encapsulation cover and a touch substrate disposed oppositely;
- and
- a first sealant disposed between the encapsulation cover and the touch substrate, wherein the encapsulation cover, the touch substrate and the first sealant are enclosed to form a first cavity, and the first cavity is filled with a transparent filling layer.
11-15. (canceled)
A fabrication method of a touch display device, comprising following steps:
- providing a touch panel and a display panel, wherein providing the touch panel comprises:
- providing an encapsulation cover and a touch substrate;
- and
- forming a first sealant between the encapsulation cover and the touch substrate, wherein the encapsulation cover and the touch substrate are aligned so that the encapsulation cover, the touch substrate and the first sealant are enclosed form a first cavity, and the first cavity is filled with a transparent filling layer;
- forming a second sealant between the touch panel and the display panel, wherein the touch panel and the display panel are aligned so that the display panel, the touch panel, and the second sealant are enclosed to form a second cavity;
- and
- reducing an air pressure in the second cavity so that the air pressure in the second cavity is lower than an atmospheric pressure outside the second cavity.
