Sealant Structure for Display Panels Using Gap-Filling Colloids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for bonding display panels using thermoplastic glues face challenges with precise stitching and sealing due to gaps between adhesive strips, which can lead to unsealed panels either from incomplete filling or excessive thickness causing splicing gaps.
Innovation Solution
A sealant structure comprising adhesive strips with gaps filled by fluid, curable colloids forming a closed loop, where the colloids expand after curing to ensure complete sealing and reduce the need for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive strips are placed end to end with gaps between them, then the sealing reliability is improved by eliminating overlapping regions, but the manufacturing precision requirement increases due to the need for precise gap control
Solution Approach 1:
The patent introduces filling colloid as an intermediary substance placed in the gaps between adhesive strips. This mediator fills the gaps and ensures continuous sealing without requiring extremely precise gap control, thus resolving the contradiction between sealing reliability and manufacturing precision requirements
Solution Approach 2:
The patent changes the physical state parameter of the filling colloid from liquid (before curing) to solid (after curing). This parameter change allows the colloid to flow into gaps during application and then maintain structural integrity after curing, ensuring reliable sealing while tolerating variations in gap dimensions
2Adaptability or versatility
If the width of adhesive strips is reduced to match narrower frame widths, then the adaptability to modern display panel designs is improved, but the stitching precision requirement increases making the ease of manufacture worse
Solution Approach 1:
The filling colloid acts as a mediator that compensates for alignment errors in narrow adhesive strips. By filling the gaps between strips, it enables successful sealing even when stitching precision is limited, thus allowing adaptation to narrow frame designs without excessively high manufacturing requirements
Solution Approach 2:
The patent divides the sealing function into two segments: adhesive strips provide the primary bonding function, while filling colloids provide the gap-filling and sealing function. This segmentation allows each component to be optimized independently, enabling the use of narrower strips while maintaining ease of manufacture through the compensating filling colloid

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution optimizes the sealing effect by eliminating overlapping regions and ensuring complete filling of gaps, enhancing the tolerance range for adhesive strip placement and alignment precision without increasing process complexity.
Implementation Method 1
a volume of each filling colloid after curing is larger than a volume of a gap in which the filling colloid is disposed
Implementation Method 2
the filling colloids have fluidity before curing, and a volume of each filling colloid after curing is larger than a volume of a gap
Implementation Method 3
Adhesive strips of the thermoplastic glues can be melted after being heated and solidified to a high viscosity solid after the temperature is lowered
