Display Device Firmware Version Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face difficulties in operating in association with each other when firmware versions are mismatched, leading to challenges in updating firmware across connected devices.
Innovation Solution
A control method for display devices that involves receiving selection of another device, acquiring version information, inquiring about firmware update propriety, transmitting acquisition requests, and installing updated firmware to ensure compatibility across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If firmware update is rejected by the display device, then firmware version compatibility is maintained, but devices cannot operate in association with each other
Solution Approach 1:
The system performs preliminary firmware version comparison between connected display devices before attempting to establish association. When version mismatch is detected, the older firmware is proactively updated to match the newer version, preventing compatibility rejection and enabling successful device association.
Solution Approach 2:
The firmware version parameter is dynamically changed by updating the older firmware to the newer version. This parameter change resolves the version mismatch conflict, allowing devices with previously incompatible firmware versions to operate in association with each other.
2Productivity
If firmware is updated to newer version, then device functionality is improved, but unintended updates may occur without user knowledge
Solution Approach 1:
The system provides feedback to the user by displaying information about the detected firmware version mismatch and the proposed update action. The user is prompted to confirm whether to proceed with the firmware update, ensuring awareness and control over the update process while still enabling functionality improvement.
Solution Approach 2:
The system takes preliminary anti-action by preventing unintended firmware updates through user confirmation prompts. Before executing the firmware update, the system alerts the user and requires explicit permission, thereby counteracting potential harmful effects of unauthorized or unintended updates while preserving the benefit of functionality improvement when user-approved.
3Reliability
If firmware version check is performed before device association, then compatibility is ensured, but additional processing time is required
Solution Approach 1:
The firmware version check and comparison are performed as a preliminary action during the device association setup process. By integrating this check into the initial connection workflow rather than as a separate subsequent step, the system ensures compatibility is verified upfront while minimizing additional perceived time loss for the user.

AI summary
A control method for a display device includes, in a state in which first firmware is installed, acquiring version information of second firmware installed in another display device from the other display device, inquiring the other display device about propriety of update of the second firmware to the first firmware when a version of the second firmware is older than a version of the first firmware, receiving the second firmware from the other display device when a notification for denying the update of the second firmware is received from the other display device, and updating the first firmware installed in the display device to the second firmware.
