Bendable Display Panel Metal Layout for Crack-Resistant Bending Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, particularly those with bendable panels, are prone to cracking in the bending areas due to structural weaknesses, which can lead to process inefficiencies and damage.
Innovation Solution
Incorporating metals in the bending area adjacent to the link area, with specific insulation layers and patterns, to strengthen the display device and prevent cracks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is made bendable to increase adaptability, then the device can be folded or curved for compact storage, but the bending area becomes prone to cracking due to structural weakness
Solution Approach 1:
The patent applies different structural characteristics to different areas of the display panel. The bending area is specifically reinforced with additional insulation layers and metal patterns compared to non-bending areas, creating local structural quality that prevents cracking while maintaining flexibility where needed
Solution Approach 2:
The patent uses composite structures combining multiple materials with different properties: flexible substrate materials for bendability, reinforced with rigid metal patterns and multiple insulation layers for crack prevention. This composite approach allows the panel to be both flexible and durable
2Reliability
If metals are added to the bending area to strengthen it, then crack resistance improves, but the device complexity increases due to additional layers and patterns
Solution Approach 1:
The patent divides the display panel into distinct functional areas: bending areas with reinforced structures and non-bending areas with standard structures. This segmentation allows complexity to be concentrated only where needed for crack prevention, rather than uniformly across the entire panel
Solution Approach 2:
The patent applies reinforcement structures (additional insulation layers and metal patterns) partially only in the bending areas where cracks are likely to occur, rather than across the entire panel. This partial action provides sufficient crack resistance while minimizing overall device complexity

AI summary
A display device may include a substrate, a first metal on the substrate, a first insulation layer on the first metal, and a first metal pattern disposed on the first insulation layer, electrically connected to the first metal, and extending through an edge side surface of the first insulation layer to at least a partial area in the bending area. Examples of such a display device may prevent cracks.
