Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal display panels experience misalignment between upper and lower substrates due to displacement during manufacturing and handling, leading to light leakage and color mixing issues.
Innovation Solution
A display panel design featuring a wiring pattern in the peripheral area of one substrate and spacers on the opposing substrate to form restriction regions, preventing substrate displacement in specific directions, thereby maintaining alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sealing rubber between substrates is not cured during manufacturing, then substrates can be assembled, but substrates are prone to displacement during processing and transportation
Solution Approach 1:
The patent applies preliminary action by pre-forming restriction regions with specific patterns (such as tooth-shaped, comb-shaped, or grid-shaped structures) on one substrate before assembly. These pre-formed structures work together with corresponding spacers on the other substrate to create mechanical interlocking that prevents displacement. The restriction regions are designed in advance with specific geometries that engage with spacers to maintain precise alignment throughout manufacturing, processing, and transportation.
2Adaptability or versatility
If extrusion and bending forces are applied from the Y direction, then local deformation occurs, but after deformation restores it creates misalignment between substrates
Solution Approach 1:
The patent applies preliminary anti-action by designing restriction regions with enhanced mechanical interlocking features that resist deformation forces before they can cause misalignment. The tooth-shaped, comb-shaped, or grid-shaped restriction regions work with spacers to create a rigid mechanical connection that counteracts extrusion and bending forces from the Y direction. This preliminary structural reinforcement prevents local deformation from translating into substrate misalignment, maintaining alignment even under mechanical stress.
3Manufacturing precision
If substrates are displaced in the X direction, then primary color portions and array substrate portions have displacement deviation, but adding restriction structures increases device complexity
Solution Approach 1:
The patent applies merging by combining the alignment restriction function with existing spacer structures used for maintaining substrate spacing. The spacers serve dual purposes: maintaining the designed gap between substrates and providing mechanical interlocking through the restriction regions. This integration eliminates the need for separate alignment structures, reducing overall device complexity while effectively preventing X-direction displacement and maintaining substrate alignment.
