Regional Dye Liquid Crystal Layers for Uniform Light Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing dye liquid crystal light adjusting hollow glass assemblies, alignment directions of functional sub-layers are confused during stacking, leading to non-uniform light transmittance and chromaticity, and increasing manufacturing costs due to the large number of sub-layers that need to be spliced.
Innovation Solution
A light adjusting structure with functional sub-layers distributed in different regions, using full-layer planar substrates and electrodes, and sealed dye liquid crystal layers with isolated spaces, allowing independent voltage control for regional light adjustment and reducing the need for splicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If functional sub-layers are cut and spliced to adapt to different scenes, then the adaptability of light adjusting is improved, but the alignment directions become confused and uniformity of light adjusting deteriorates
Solution Approach 1:
The patent divides the functional layer into multiple functional sub-layers (first functional sub-layer and second functional sub-layer) with different alignment directions. Each sub-layer can be independently controlled to achieve different light adjusting effects (transparent state, dimming state, different colors), providing adaptability for different scenes while maintaining clear alignment direction boundaries to avoid confusion during stacking.
2Manufacturing precision
If multiple functional sub-layers are spliced together, then the uniformity of light adjusting is improved, but the number of splicing operations increases and manufacturing cost rises
Solution Approach 1:
The patent combines multiple functional sub-layers with different alignment directions into a single integrated functional layer structure. The first and second functional sub-layers are arranged adjacent to each other within the same functional layer, eliminating the need for multiple separate splicing operations while maintaining the uniformity of light adjusting across different regions.
3Manufacturing precision
If multiple functional sub-layers are spliced together, then the uniformity of light adjusting is improved, but the production efficiency decreases
Solution Approach 1:
The patent performs preliminary arrangement of functional sub-layers with different alignment directions during the manufacturing process. The first and second functional sub-layers are pre-positioned adjacent to each other with clearly defined alignment directions (e.g., first alignment direction and second alignment direction that are perpendicular or at an angle), eliminating the need for complex alignment operations during assembly and improving production efficiency.
