Display Device ID Display for Simplified Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display device control methods require multiple steps to execute simple commands, making the operation procedure cumbersome, especially when controlling individual display devices within a group.
Innovation Solution
A display device configuration that includes a command receiving unit and a command processing unit, allowing the display device to automatically display its ID and process control commands with reduced resource usage, requiring only two steps: transmitting a control command and designating the target device's ID.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a display device displays its ID and requires ID designation before command execution, then the controller can identify the target display device, but the number of operation steps increases making simple commands more troublesome
Solution Approach 1:
The display device performs preliminary action by automatically displaying its own ID when a control command is received, eliminating the need for the controller to query or the user to manually check device IDs. This preliminary display of identification information streamlines the subsequent command execution process.
Solution Approach 2:
Instead of the conventional approach where the controller queries device IDs first and then receives commands, this invention inverts the sequence: the display device proactively displays its ID in response to receiving a control command. This reversal eliminates unnecessary steps and makes the control process more efficient.
2Ease of operation
If the display device automatically displays its ID upon receiving a control command, then the user can easily identify and select the target device, but the device complexity increases due to additional processing logic
Solution Approach 1:
The display device serves itself by automatically displaying its own ID information when a control command is received. This self-service capability eliminates the need for complex external query mechanisms or manual identification procedures, simplifying the overall control system while improving ease of operation.
3Productivity
If the display device stores and processes command information internally, then the device can execute commands autonomously without continuous controller communication, but the storage and processing resources are consumed
Solution Approach 1:
Instead of storing complete command sequences or extensive control data, the display device performs partial action by storing only the essential command type information and its own ID. This minimal storage approach provides sufficient autonomy for command execution while avoiding excessive consumption of storage resources.
Data Source
AI summary
A display device that can be used with another display device, includes: a display unit; a command receiving unit which receives a control command or ID information from an external remote controller; and a command processing unit. The display unit displays the display device's own ID in response to reception of the control command by the command receiving unit. If the command receiving unit receives the ID information indicating the display device's own ID after the display unit starts displaying the display device's own ID, the command processing unit performs processing corresponding to the control command.
