Display Device Terminal Detection for Wireless Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer systems between display devices and portable information terminals require complex cable connections or wireless pairings, making them cumbersome and inconvenient.
Innovation Solution
A data transfer system that uses a display device with a touch panel to detect the approach of a portable information terminal, displaying a storage location image which is captured by the terminal's imaging unit, allowing data transfer via a cloud server without direct connections or pairings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable connection or wireless pairing is used to transfer data between display device and portable information terminal, then data transfer reliability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The display device automatically detects the portable information terminal using a terminal detection unit and displays storage location information without requiring user initiation of pairing or connection procedures. The system serves itself by automatically establishing the data transfer pathway when the terminal approaches, eliminating the need for manual cable connection or wireless pairing operations while maintaining reliable data transfer
Solution Approach 2:
The display device performs preliminary detection of the portable information terminal before data transfer is requested. By using the terminal detection unit to identify the terminal's approach and pre-displaying storage location information on the display screen, the system prepares the data transfer pathway in advance, so that when the user wants to transfer data, the connection is already established and ready for immediate use
2Reliability
If cable connection or wireless pairing is used to transfer data between display device and portable information terminal, then data transfer reliability is improved, but device complexity deteriorates
Solution Approach 1:
The patent extracts the connection establishment function from the user's operational responsibility and places it in the display device's automatic detection and display system. The terminal detection unit and display processing unit handle the connection setup independently, removing the need for users to perform cable connection or wireless pairing operations, thereby simplifying the user interface while maintaining reliable data transfer through automated connection management
Solution Approach 2:
The display screen acts as an intermediary between the terminal detection unit and the user. Instead of directly implementing cable connection or wireless pairing protocols that would require complex user interaction, the system uses the display screen to present storage location information, which the portable information terminal then captures through its imaging unit. This intermediary approach simplifies the connection process while maintaining data transfer reliability

AI summary
A display device includes a display panel including a display screen for displaying an image, and a terminal detection unit. When the terminal detection unit detects that a portable information terminal is arranged on the display screen, the display device transmits a data area generation instruction to secure a data area to a storage device to cause the storage device to secure the data area. The display device receives information indicating a location of the data area from the storage device. The display device causes the display screen to display a storage location image including the information indicating the location of the data area on a part of the display screen on which the portable information terminal is arranged, and notifies the portable information terminal of the location of the data area through the storage location image.
