Display Device Bluetooth Handover via Screen Link Command
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require users to manually disconnect and reconnect Bluetooth devices when switching between TVs, causing inconvenience and requiring additional steps to update voice settings.
Innovation Solution
A display device equipped with a Bluetooth communication circuit, a WiFi circuit, and a controller that can automatically detect a screen link command and perform a seamless handover of the Bluetooth connection to an external device, along with automatic voice setting synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual disconnection and reconnection of Bluetooth device is performed when switching between TVs, then Bluetooth connection can be established with the new TV, but user convenience deteriorates and operation complexity increases
Solution Approach 1:
The system performs preliminary actions by detecting the screen link command in advance and automatically initiating the Bluetooth disconnection and reconnection process before the user needs to manually switch devices. The controller monitors for screen link commands and proactively manages the Bluetooth handover, eliminating the need for user intervention.
Solution Approach 2:
The system serves itself by automatically detecting when a screen link command is received and autonomously managing the Bluetooth device handover process. The controller independently handles disconnection from the first TV, connection to the second TV, and voice setting synchronization without requiring user actions, making the system self-sufficient in resolving the switching problem.
2Reliability
If manual voice settings update is performed when connecting Bluetooth device to a new TV, then voice recognition accuracy improves, but time consumption and operation complexity increase
Solution Approach 1:
The system performs preliminary action by automatically copying and applying voice settings from the first TV to the second TV during the Bluetooth handover process. The controller retrieves stored voice settings and applies them in advance, ensuring voice recognition accuracy is maintained without requiring the user to manually reconfigure settings after connection.
Solution Approach 2:
The system merges the Bluetooth connection process with the voice settings synchronization process. Instead of treating them as separate operations, the controller combines both tasks into a single automated handover sequence, where connection establishment and settings transfer occur simultaneously, reducing total time and operation steps.
3Productivity
If automatic handover of Bluetooth device is implemented, then user convenience and operation speed improve, but system complexity and control difficulty increase
Solution Approach 1:
The controller is designed with multi-functionality, handling both screen link command detection and Bluetooth device management within a single component. This universal approach consolidates control functions, reducing the need for additional dedicated hardware or software modules, thereby limiting the increase in system complexity while achieving automatic handover.
Solution Approach 2:
The system implements feedback mechanisms by monitoring screen link commands and automatically responding with appropriate Bluetooth handover actions. The controller continuously checks for screen link commands and adjusts Bluetooth connections based on this feedback, creating a closed-loop system that automates handover without requiring complex user input or additional control infrastructure.

AI summary
A display device includes a display, a Bluetooth communication circuit configured to communicate with an audio output device through Bluetooth, a WiFi circuit configured to WiFi communicate with an external device, and a controller configured to obtain a screen link command while transmitting audio data to the audio output device through the Bluetooth communication circuit, determine whether to perform handover to switch Bluetooth connection with the audio output device to the external device depending on the obtained screen link command, and stop connection with the audio output device based on determining to perform the handover.
