Display Apparatus Automatic External Device Connection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when connecting multiple external apparatuses to a display apparatus, as they need to specify and operate each apparatus before connecting, which can be time-consuming and labor-intensive.
Innovation Solution
A control method for a display apparatus that automatically detects and connects to external apparatuses by transmitting signals and displaying selection screens, allowing users to select and connect devices without manual operation, while also storing connection history for automatic reconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display apparatus requires users to manually specify and operate each external apparatus before connection, then connection reliability is ensured, but user labor and time consumption increase
Solution Approach 1:
The display apparatus automatically detects external apparatuses in the wireless network and displays their information on the selection screen without requiring users to manually operate each external apparatus. The system serves itself by autonomously gathering device information and presenting connection options, thereby reducing user labor while maintaining reliable connections through informed selection.
Solution Approach 2:
The display apparatus performs preliminary detection and information gathering about external apparatuses before the actual connection process. By automatically obtaining and displaying device information in advance, the system prepares the connection environment beforehand, reducing the time and effort users would otherwise spend on manual specification and operation.
2Ease of operation
If the display apparatus automatically detects and connects to external apparatuses, then user labor is reduced, but connection time may increase due to signal transmission and detection delays
Solution Approach 1:
The display apparatus performs automatic detection and information gathering about external apparatuses in advance, before the user needs to make a selection. By preparing the list of available devices and their information beforehand, the system reduces the overall connection time even though automatic detection is performed, as users don't need to manually search or specify devices.
Solution Approach 2:
The system performs automatic detection and displays information for all external apparatuses in the network rather than waiting for specific user requests. This excessive action of pre-detecting all devices ensures that when connection is needed, the process is already underway or completed, reducing perceived connection time for the user.
3Ease of operation
If the display apparatus displays information about multiple external apparatuses simultaneously, then user selection is simplified, but information processing complexity increases
Solution Approach 1:
The display apparatus segments the information about multiple external apparatuses into individual entries on the selection screen, with each apparatus presented as a separate selectable option. This segmentation allows users to easily distinguish and select between devices while the system processes information in an organized, manageable structure, reducing the perceived complexity for both user and system.

AI summary
A control method for a display apparatus including an operation receiving section that receives operation, the control method including transmitting a first signal, receiving a second signal transmitted from a first external apparatus that receives the first signal and a third signal transmitted from a second external apparatus that receives the first signal, displaying, when receiving the second signal and the third signal, on a display surface, a first image including information concerning the first external apparatus and information concerning the second external apparatus, executing processing for connection to the first external apparatus when the operation receiving section receives, in a state in which the first image is displayed on the display surface, first operation for selecting the first external apparatus, and displaying a second image corresponding to an image signal transmitted from the first external apparatus after the display apparatus is connected to the first external apparatus.
