Removable Adhesive Member for Display Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal display and touch display modules face challenges in disassembly due to strong adhesives, which can damage the backlight module and increase manufacturing costs, especially when trying to achieve a narrow bezel design.
Innovation Solution
A removable adhesive member with a tearing portion and connecting section is used, allowing for easy disassembly without damaging the products by providing a force-based removal mechanism that avoids rupture and reduces adhesive area and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If strong adhesives are used to assemble the backlight module with the back cover, then the adhesion strength is improved, but the ease of disassembly deteriorates
Solution Approach 1:
The adhesive member is segmented into three functional sections: an adhesive section for bonding, a connecting section for structural support, and a tearing portion for removal. This segmentation allows the adhesive member to provide strong adhesion during assembly while enabling easy disassembly by tearing the tearing portion, thus resolving the contradiction between strong adhesion and ease of disassembly.
2Area of stationary object
If the adhesive area is reduced to achieve narrow bezel design, then the screen-to-body ratio is improved, but the adhesion strength deteriorates
Solution Approach 1:
The adhesive member employs local quality by concentrating adhesion function in the adhesive section while providing structural integrity through the connecting section and removal capability through the tearing portion. This allows the adhesive member to maintain strong bonding with reduced overall area, enabling narrow bezel design without sacrificing adhesion strength.
3Area of stationary object
If the adhesive area is reduced to achieve narrow bezel design, then the screen-to-body ratio is improved, but the reliability of assembly deteriorates
Solution Approach 1:
The adhesive member employs local quality by concentrating adhesion function in the adhesive section while providing structural integrity through the connecting section and removal capability through the tearing portion. This allows the adhesive member to maintain strong bonding with reduced overall area, enabling narrow bezel design without sacrificing adhesion strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates rapid disassembly of display modules without damaging the backlight module, reducing manufacturing costs and time, while maintaining a narrow bezel design.
Implementation Method 1
The first adhesive section extends along a first direction to form the first adhesive layer. The two opposite surfaces of the first adhesive section respectively adhere to the two objects.
Implementation Method 2
The tearing portion is pulled up with a force to pull the first connecting section until the first adhesive section removes from the objects to disassemble the objects.

AI summary
A removable adhesive member and a display device using the same is provided. The removable adhesive member includes a first adhesive section, a first connecting section, and a tearing portion. The two opposite surfaces of the first adhesive section respectively adhere to the two objects. The first connecting section is connected to the first adhesive section. The first connecting section includes a first adhesive layer and two first protective layers. One side of the first adhesive section extends to form the first adhesive layer. The first protective layers are respectively laminated to two opposite surfaces of the first adhesive layer. The tearing portion is connected to the first adhesive section through the first connecting section, thereby avoiding rupture in pulling the tearing portion. The tearing portion is conveniently pulled up by a user, such that the first adhesive section removes from the objects to disassemble the objects.
