Solution Overview
Problem
The uneven coating and poor curing of sealants in display device manufacturing due to the presence of metal trace structures that reflect UV light, leading to inconsistent UV light irradiation and reduced bonding stability.
Innovation Solution
Incorporating a metal structure with a similar area to the metal trace structure in the sealant coating region, ensuring uniform metal reflectivity and consistent UV light irradiation, thereby maintaining even sealant coating and improved curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal trace structure is provided on the array substrate in the sealant coating region to increase bonding stability, then bonding stability is improved, but the sealant coating becomes uneven and UV light irradiation becomes inconsistent
Solution Approach 1:
The patent applies local quality by providing metal structures at specific locations within the sealant coating region rather than uniformly across the entire region. The metal structures are strategically positioned to enhance bonding stability while minimizing interference with sealant coating uniformity and UV light irradiation consistency.
Solution Approach 2:
The patent changes parameters of the metal structures including their size, shape, spacing, and distribution density within the sealant coating region. By optimizing these parameters, the patent achieves a balance between improving bonding stability and maintaining uniform sealant coating and consistent UV light irradiation.
2Reliability
If a metal trace structure is provided in part of the sealant coating region, then bonding stability is enhanced, but UV light reflection becomes inconsistent causing poor sealant curing
Solution Approach 1:
The patent applies equipotentiality by designing the metal structures to create uniform UV light reflection characteristics across the sealant coating region. The metal structures are configured to ensure consistent UV light irradiation intensity, preventing poor sealant curing while maintaining enhanced bonding stability.
Solution Approach 2:
The patent uses partial action by providing metal structures in specific areas of the sealant coating region rather than throughout the entire region. This partial placement optimizes bonding stability while minimizing negative effects on UV light irradiation consistency.
3Device complexity
If the sealant coating region is not entirely coated with metal trace structure, then manufacturing complexity is reduced, but sealant arrangement becomes uneven
Solution Approach 1:
The patent applies segmentation by dividing the sealant coating region into multiple areas with different metal structure configurations. This segmentation allows the metal structures to be arranged in a pattern that maintains sealant arrangement uniformity while avoiding excessive manufacturing complexity.

Function Achieved in This Case
The solution ensures uniform sealant coating and consistent UV light irradiation, addressing the issues of uneven coating and poor curing, and enhancing bonding stability in display device manufacturing.
Implementation Method 1
a metal can reflect the UV light. Therefore, the provision of the metal trace structure that can reflect the UV light in a part of the sealant coating legion makes UV light irradiation powers inconsistent
