Protective Adhesive Tape Structure for Foldable Display Grounding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face poor waterproof performance due to gaps between the screen and middle frame, and conventional waterproof adhesives compromise electrostatic shielding.
Innovation Solution
An electronic device protection structure featuring a substrate with a component group, a first protective adhesive tape covering the component group and extending to contact the substrate, and a second protective adhesive tape attached to the periphery, electrically connected to the first tape, ensuring grounding and avoiding wrinkles and pseudo sticking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective adhesive tape is extended to contact substrate for grounding, then electrostatic discharge path is established, but attachment complexity increases
Solution Approach 1:
The grounding function is extracted from the first protective adhesive tape and assigned to the second protective adhesive tape. The second tape is specifically designed to be electrically connected to the substrate, providing grounding capability while simplifying the overall attachment process by separating grounding from electrostatic shielding functions

Function Achieved in This Case
Enhances waterproof and electrostatic shielding performance by preventing wrinkles and pseudo sticking, thus improving the overall protection of foldable products.
Implementation Method 1
a second protective adhesive tape attached to a periphery of the component group and electrically connected to the lapping portion
Implementation Method 2
the waterproof function cannot be achieved through a shell

AI summary
An electronic device protection structure includes: a substrate, a component group on a side of the substrate, a first protective adhesive tape on a side of the component group away from the substrate, and a second protective adhesive tape on a side of the first protective adhesive tape away from the component group. The first protective adhesive tape includes a covering portion covering the component group, and a lapping portion extending from at least one side of the covering portion until the lapping portion comes into contact with the substrate. The second protective adhesive tape is attached to the periphery of the component group, and is electrically connected to the lapping portion.
