Display Panel Base Member With Integral Adhesive Layer Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in efficiently stacking components like a support member and a spacer on a display panel without causing damage, necessitating a complex adhesive layer application process.
Innovation Solution
The integration of a base member with integral adhesive layers for attaching a base film, support member, and spacer to a display panel simplifies the stacking process by eliminating the need for separate adhesive layers on the support member and spacer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate adhesive layers are applied on the support member and spacer, then the display panel can be protected during stacking, but the fabrication process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple separate adhesive layers into a single integrated adhesive layer that simultaneously bonds the base film to both the support member and spacer. This merging eliminates the complexity of applying and aligning multiple adhesive layers while maintaining the protective function during the stacking process
Solution Approach 2:
The single adhesive layer is designed to perform multiple functions: it protects the display panel during stacking, bonds the base film to the support member, and bonds the base film to the spacer. This multi-functional adhesive layer replaces what would traditionally require separate adhesive applications
2Strength
If multiple separate adhesive layers are used, then each component can be securely attached, but the manufacturing time and process steps increase
Solution Approach 1:
Multiple adhesive application steps are merged into a single adhesive layer formation process. The adhesive layer is applied once and then used to attach multiple components (base film, support member, and spacer) in sequence, thereby maintaining secure attachment while significantly reducing manufacturing time and process steps
3Ease of manufacture
If a base member with integral adhesive layers is used, then the stacking process is simplified, but the base member structure becomes more complex
Solution Approach 1:
The base member integrates the base film and adhesive layer into a single pre-assembled unit. This merging simplifies the stacking process because the adhesive layer is already in position and ready for bonding, eliminating the need for separate adhesive application steps during assembly

AI summary
A display device including: a display panel; a base member on a surface of the display panel; a support member on a surface of the base member; and a spacer on the surface of the base member. The base member includes: a base film; a fourth adhesive layer between the base film and the display panel; and a fifth adhesive layer between the base film and the support member and between the base film and the spacer, and the base film, the fourth adhesive layer, and the fifth adhesive layer are integrally formed.
