Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with openings face challenges in integrating additional functions while maintaining structural integrity and functionality, particularly in areas surrounding the opening.
Innovation Solution
A display device design featuring a substrate with an opening area surrounded by a display area, incorporating a metal layer with regions that include protrusions and sensing electrodes, and connection electrodes to enhance structural support and input sensing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an opening area is introduced in the display device to add functions, then the versatility and functionality are improved, but the structural integrity and reliability in the surrounding areas deteriorate
Solution Approach 1:
The metal layer is divided into multiple separate regions (first region, second region, third region) that are spaced apart from each other. Each region can be independently designed and optimized, allowing the structure to accommodate the opening area while maintaining overall integrity through distributed support points rather than a continuous structure.
Solution Approach 2:
Different regions of the metal layer are given different configurations (some with protrusions, some without) based on their specific functional requirements. The regions adjacent to the opening area have special designs to provide enhanced local support where needed, while other areas maintain simpler structures.
2Reliability
If metal layers are placed adjacent to the opening area to maintain structural support, then the structural integrity is improved, but the complexity of the metal layer configuration increases
Solution Approach 1:
The metal layer is segmented into discrete regions with clear spacing between them. This segmentation simplifies the design by allowing each region to be independently optimized without requiring complex continuous structures, making the overall configuration more manageable despite the presence of the opening area.
Solution Approach 2:
Instead of creating a continuous metal layer that must be interrupted by the opening area (which would create complexity), the design inverts the approach by using discrete spaced-apart regions. This eliminates the need for complex routing and connection designs that would be required to maintain continuity around the opening.
3Measurement precision
If protrusions are added to metal layer regions to enhance input sensing, then the sensing capability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The metal layer is divided into multiple regions with protrusions, allowing the sensing function to be distributed across several locations rather than requiring one large complex structure. This segmentation enables each protrusion to be smaller and simpler to manufacture with consistent precision.
Solution Approach 2:
Protrusions are added only to specific metal layer regions where input sensing is required, rather than uniformly across the entire metal layer. This localized approach concentrates the manufacturing precision requirements on specific small features rather than a large area, making high precision more achievable.

AI summary
A display device includes a substrate including an opening area and a display area at least partially surrounding the opening area; and a metal layer including a first region and a second region adjacent to a non-display area between the opening area and the display area, the first region and the second region are spaced apart from each other, and one of the first region and the second region includes a protrusion extending toward the other of the first region and the second region, and the other of the first region and the second region has a shape to receive the protrusion.
