Title:
BACK ADHESIVE STRUCTURE AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/066329
Kind Code:
A1
Abstract:
The present application discloses a back adhesive structure and a terminal device, which relate to the technical field of back adhesives. The back adhesive structure comprises a release film and a back adhesive layer. The release film is provided with a first side edge and a second side edge which are opposite to each other, the first side edge being connected to a tearing part. The back adhesive layer and the release film are stacked. The back adhesive layer comprises at least one block which is provided with at least one first flow channel. The length of the first flow channel extends in the length extension direction of the first side edge of the release film. The first flow channel is provided with a first flow channel wall and a second flow channel wall which extend in the length direction of the first flow channel and are opposite to each other. The first flow channel wall faces the initial tearing direction of the tearing part, and the second flow channel is away from the initial tearing direction of the tearing part, wherein the length of the first flow channel wall is not less than a first set value. The terminal device comprises the back adhesive layer in the back adhesive structure. According to the present application, when the release film protecting the back adhesive is torn, the possibility that the back adhesive is wrinkled due to the back adhesive being taken up is reduced.
