Distance Separator with UV Openings for Display Adhesive Hardening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Organic light-emitting display apparatuses are prone to damage when dropped due to the gap between the display panel and the window cover, which can cause structural weakness and hinder the proper hardening of adhesives used between components.
Innovation Solution
A display apparatus design that includes a distance separator with spacers and openings to maintain structural integrity and allow UV rays to harden adhesives between the display panel, functional films, and window cover, ensuring effective bonding and shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a gap is provided between the display panel and window cover, then shock absorption and structural flexibility are improved, but structural strength and damage resistance deteriorate
Solution Approach 1:
The distance separator is divided into multiple spacers arranged in a matrix pattern, creating segmented support points that maintain the gap while distributing mechanical stress across multiple locations, thereby preventing concentrated damage
Solution Approach 2:
The distance separator combines materials with different properties: the spacer body provides mechanical support and gap maintenance, while the opening regions allow UV transmission for adhesive hardening, creating a composite structure that achieves multiple functions simultaneously
2Strength
If spacers are provided to maintain distance, then structural strength is improved, but UV ray penetration for adhesive hardening is blocked
Solution Approach 1:
The distance separator features localized openings in specific regions that allow UV rays to penetrate through to the adhesive layers, while the surrounding spacer material maintains the structural gap. This creates different functional zones within the same component
Solution Approach 2:
The distance separator incorporates opening regions that function similarly to porous structures, allowing UV radiation to pass through the spacer material to reach and harden the adhesive layers beneath, while the solid portions maintain mechanical separation
3Strength
If adhesive is applied between display panel and window cover, then bonding strength is improved, but adhesive hardening is hindered due to gap and spacer obstruction
Solution Approach 1:
The openings in the distance separator act as intermediary channels that allow UV rays to reach the adhesive layers, mediating between the need for mechanical gap maintenance and the requirement for adhesive hardening. The adhesive is applied in regions accessible through these opening paths
