Display Device Bluetooth Connection Cut Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often fail to recognize a cut-off of Bluetooth connections between display devices and Bluetooth remote controllers, leading to continued use of IR communication, which negates the benefits of Bluetooth such as reduced power consumption and long-distance control.
Innovation Solution
A display device equipped with a processor that monitors the Bluetooth connection in real time, counts the number of connection cuts, and displays a user interface (UI) to prompt the user for pairing when the connection is cut off a predetermined number of times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If Bluetooth communication is used for remote control, then power consumption is reduced and long-distance control is enabled, but users may not recognize when the Bluetooth connection is cut off and continue using IR communication
Solution Approach 1:
The display device implements a feedback mechanism by monitoring Bluetooth connection status and providing visual notifications through a UI display. When the Bluetooth connection is cut off, the system detects this change and presents a notification interface to inform the user, ensuring awareness of the connection state while maintaining the energy-efficient Bluetooth mode.
2Length of moving object
If Bluetooth remote controller is used, then control in long distance and various control ways are enabled, but frequency synchronization issues and electric wave interference can cause connection failure
Solution Approach 1:
The system prepares for potential connection failures by implementing proactive monitoring of Bluetooth connection status. Before complete disconnection occurs, the system detects connection deterioration and notifies the user in advance, allowing for timely intervention to restore the reliable Bluetooth connection before it completely fails.
3Use of energy by moving object
If Bluetooth remote controller is used, then power consumption is reduced, but additional complexity is needed to monitor and notify users of connection status
Solution Approach 1:
The display device leverages its existing display unit, which serves multiple functions including content presentation and system status notification. By utilizing the same display infrastructure for both primary content display and Bluetooth connection status notifications, the system avoids adding separate dedicated notification hardware, thereby minimizing additional complexity while maintaining energy-efficient Bluetooth operation.

Function Achieved in This Case
This solution ensures users are informed of Bluetooth connection cuts, prompting them to re-establish the Bluetooth connection, thereby allowing them to enjoy the benefits of Bluetooth remote control, such as reduced power consumption and long-distance control, while preventing unnecessary IR communication.
Implementation Method 1
a communication unit, and a processor configured to receive an InfraRed (IR) signal from a remote controller through the communication unit
Data Source
AI summary
A display device comprises a display unit, a communication unit and a processor, which identifies, based on an IR signal received through the communication unit, whether there is a pairing history of a remote controller and the display device, identifies whether there is a Bluetooth connection between the display device and the remote controller, counts a number of times the Bluetooth connection had been cut off between the display device and the remote controller, and controls, based on the counted number of times the Bluetooth connection had been cut off, the display unit so that a user interface (UI) for pairing with the remote controller is displayed.
