Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with near-field communication technology face challenges due to the need for a large space for the near-field communication module, which hinders lightweight design and increases electromagnetic interference with display signals.
Innovation Solution
The integration of a near-field communication antenna on a color film substrate within a display panel, with the coil structure partially located in the display area and aligned to avoid overlapping with channel regions on the array substrate, reducing electromagnetic interference and allowing for a thinner border.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate near-field communication module is used, then near-field communication function is achieved, but device weight and size increase
Solution Approach 1:
The patent combines the near-field communication antenna with the display panel by integrating the antenna coil structure into the display area, allowing the antenna to share the same physical space as the display components rather than requiring a separate module, thereby reducing overall device weight and size
2Reliability
If a separate near-field communication module is used, then near-field communication function is achieved, but device size increases
Solution Approach 1:
The patent merges the near-field communication antenna with the display panel by integrating the antenna coil structure into the display area, allowing the antenna to share the same physical space as the display components rather than requiring a separate module, thereby reducing overall device size
3Area of stationary object
If the coil structure is located in the display area, then space is saved, but electromagnetic interference with display signals increases
Solution Approach 1:
The patent applies local quality by positioning the coil structure specifically in the non-channel region of the display area, creating a spatial differentiation where the antenna occupies only the appropriate zone without interfering with the channel regions, thus maintaining both space efficiency and electromagnetic compatibility
Solution Approach 2:
The patent uses the non-channel region as an intermediary space that allows the coil structure to be integrated into the display area while preventing direct electromagnetic interference with the display signals, as this region is naturally suited for such components
4Reliability
If the border width is increased to accommodate the near-field communication module, then near-field communication function is achieved, but display area ratio decreases
Solution Approach 1:
The patent combines the near-field communication antenna with the display panel by integrating the antenna coil structure into the display area, allowing the antenna to share the same physical space as the display components rather than requiring a separate module, thereby maintaining the display area ratio
