Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an independent NFC module is provided external to the motherboard, then NFC communication functionality is achieved, but the device occupies relatively large space
Solution Approach 1:
The NFC antenna is integrated directly into the display substrate by forming conductive structures (first and second conductive structures) that intersect and are electrically connected through vias. This merging of the NFC antenna with the display substrate eliminates the need for a separate external NFC module, thereby reducing the overall device space while maintaining NFC communication functionality.
Solution Approach 2:
The display substrate serves dual functions: it acts as both the display component and the NFC antenna substrate. The first and second conductive structures formed on the display substrate create an NFC antenna that can transmit and receive electromagnetic wave signals, while the display substrate continues to perform its primary display function, achieving multi-functionality in a single component.
2Area of stationary object
If the NFC antenna is integrated into the display substrate, then device space is reduced for lightweight design, but display uniformity and performance may be compromised
Solution Approach 1:
The first and second conductive structures are strategically arranged in specific regions of the display substrate, allowing the NFC antenna functionality to be localized without affecting the overall display uniformity. The conductive structures are positioned to minimize interference with the display regions while maintaining effective NFC communication capability.
Solution Approach 2:
The NFC antenna is formed by creating conductive structures in multiple layers on the display substrate, with first conductive structures in one layer and second conductive structures in another layer, electrically connected through vias. This three-dimensional arrangement allows the NFC antenna to function effectively without occupying additional planar space that would interfere with display uniformity.
