Display Panel Blocking Structure Prevents Liquid Crystal Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small liquid crystal displays face challenges in successful alignment due to liquid crystals diffusing beyond the frame sealing adhesive region during the dripping process, leading to misalignment.
Innovation Solution
A display panel design that incorporates a blocking structure on the first substrate between the frame sealing adhesive and the display region, preventing liquid crystals from overflowing and ensuring they remain within the adhesive region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If liquid crystals are dripped onto the first substrate during alignment, then the liquid crystal display panel can be assembled, but the liquid crystals diffuse beyond the frame sealing adhesive region causing misalignment
Solution Approach 1:
The patent introduces a blocking structure as an intermediary element between the liquid crystals and the frame sealing adhesive. This blocking structure prevents direct contact and diffusion of liquid crystals beyond the adhesive region, thereby maintaining alignment precision while preserving the simplicity of the dripping assembly process
Solution Approach 2:
The patent segments the peripheral region into distinct functional zones: the frame sealing adhesive region and the blocking structure region. This segmentation allows the liquid crystals to be contained within the adhesive region during assembly, preventing diffusion while maintaining the ease of the dripping process
2Manufacturing precision
If the blocking structure is added to prevent liquid crystal diffusion, then alignment precision is improved, but the device structure becomes more complex
Solution Approach 1:
The patent merges the blocking structure with the peripheral region of the first substrate, making it an integrated part of the substrate rather than a separate component. This merging approach improves alignment precision by preventing liquid crystal diffusion while minimizing the increase in device complexity
