NFC Antenna Positional Overlap with Display Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses for digital signage face challenges in establishing near field communication with mobile terminals without causing malfunctions and increasing maintenance burdens, as they require mechanisms for moving reader/writer antennas to specific positions.
Innovation Solution
A display apparatus with integrated NFC antennas positioned to overlap with the display section, accompanied by a server that provides display position information to guide the mobile terminal into proximity with the antennas, facilitating communication while minimizing maintenance and malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanism for moving the reader/writer antenna to a position corresponding to a mark on the advertisement panel is employed, then near field communication can be established with mobile terminals, but malfunctions occur and maintenance burden increases
Solution Approach 1:
The patent extracts the antenna moving mechanism from the system and eliminates it entirely. Instead of moving the antenna to different positions, the system uses a single stationary antenna that communicates with mobile terminals regardless of their position on the display panel, thereby resolving the contradiction between communication reliability and device complexity
Solution Approach 2:
The antenna is designed to serve multiple positions and functions simultaneously. A single antenna can establish near field communication with mobile terminals at various locations on the display panel without requiring mechanical movement, making the system more reliable and easier to maintain
2Ease of repair
If the antenna is positioned at a fixed location on the display apparatus, then maintenance burden is reduced, but near field communication with mobile terminals at various positions becomes difficult
Solution Approach 1:
The patent extends the communication coverage of the stationary antenna across the entire display panel area. By optimizing the antenna design and signal propagation, a single fixed antenna can effectively communicate with mobile terminals positioned at various locations, eliminating the need for mechanical movement while maintaining communication reliability

AI summary
The present disclosure facilitates the establishment of near field communication with a mobile terminal while also preventing malfunctions and an increase in burden of maintenance. A display apparatus (10) includes: at least one antenna (140) for carrying out near field communication with a mobile terminal (20), the at least one antenna being provided so as to positionally overlap with a display section (160). In a case where the mobile terminal comes into proximity to the display section, the display section is caused to display a guide for bringing the mobile terminal in proximity to at least one of the at least one antenna.
