Optical Path Control Member Sealing for Moisture-Resistant Light Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical path control members face issues with moisture penetration through sealing parts, leading to reduced light conversion efficiency and visibility defects due to moisture interaction with light conversion materials.
Innovation Solution
The optical path control member features a first sealing part with a larger anchor region compared to other sealing parts, designed to inhibit moisture ingress and maintain the integrity of the light conversion material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing parts are formed in the cutting region to seal the light conversion material, then the light conversion material is sealed and protected, but external moisture can penetrate through the sealing part causing stains and reduced light conversion efficiency
Solution Approach 1:
The patent applies different anchor region sizes to different sealing parts based on their specific locations and moisture exposure risks. The first sealing part has a larger anchor region than the second sealing part, creating localized differences in sealing strength where most needed. This resolves the contradiction by providing enhanced moisture protection at critical locations without uniformly increasing complexity across all sealing structures.
Solution Approach 2:
The patent introduces asymmetry in the sealing part design by making the anchor region size of the first sealing part different from that of the second sealing part. This asymmetric design allows the structure to better resist moisture penetration from external environments while maintaining appropriate sealing at internal interfaces, thus improving reliability without uniform complexity increase.
2Object-affected harmful factors
If the anchor region of the first sealing part is made larger to prevent moisture penetration, then moisture resistance is improved, but the device complexity increases
Solution Approach 1:
The patent implements local quality by varying the anchor region size only where needed - the first sealing part has a larger anchor region for enhanced moisture resistance, while the second sealing part has a smaller anchor region. This localized differentiation improves moisture resistance without unnecessarily complicating the entire sealing structure, thus resolving the contradiction between moisture resistance and device complexity.
