Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with near-field communication technology face challenges in integrating a near-field communication antenna without increasing device size and causing electromagnetic interference, which hinders lightweight design and display performance.
Innovation Solution
The near-field communication antenna is integrated into the display panel's color film substrate, with its coil structure partially located in the display area and orthographically positioned within the non-channel region of the array substrate, minimizing electromagnetic interference and reducing the border width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If the near-field communication antenna is integrated into the display panel, then the device size can be reduced and lightweight design is supported, but electromagnetic interference with display performance may occur
Solution Approach 1:
The patent applies local quality by positioning the NFC antenna's coil structure specifically within the non-channel region of the array substrate, where it does not interfere with display pixel channels. This localized placement allows the antenna to function while avoiding electromagnetic interference with the display area, resolving the contradiction between integration and interference.
Solution Approach 2:
The patent utilizes the vertical dimension (depth layer) to resolve the contradiction. By placing the coil structure in the non-channel region on the array substrate and integrating it with the color film substrate, the design uses spatial layers to separate NFC functionality from display channels, enabling integration without electromagnetic interference.
2Length of stationary object
If the near-field communication antenna is integrated into the display panel, then the border width can be reduced, but electromagnetic interference with display quality may occur
Solution Approach 1:
The patent positions the coil structure within the non-channel region, which is a specific local area designed for such integrations. This localized placement allows the antenna to be incorporated without expanding the border width while avoiding interference with the display channels in other regions.
Solution Approach 2:
The patent merges the NFC antenna integration with the existing array substrate and color film substrate structure. By combining the coil structure placement with the non-channel region of the array substrate, the design achieves border reduction while maintaining display quality through integrated design.
3Reliability
If the coil structure is positioned in the display area, then the antenna functionality is maintained, but electromagnetic interference with display channels increases
Solution Approach 1:
The patent distinguishes between different regions of the array substrate: the channel region for display pixels and the non-channel region for antenna integration. By localizing the coil structure to the non-channel region, the design maintains antenna functionality while avoiding electromagnetic interference with display channels.
Solution Approach 2:
The patent segments the array substrate into channel regions and non-channel regions. This segmentation allows the coil structure to be placed in the non-channel region, separating NFC functionality from display channels and preventing electromagnetic interference while maintaining both functions.
