Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to visually indicate heat generation, especially when the connection between the temperature sensor and the controller is deteriorated.
Innovation Solution
A display device with a temperature sensor in the non-display area, a data driver that converts temperature data into digital form, and synthesizes a background image based on this data, displaying it in areas corresponding to high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature data is transmitted through the controller, then temperature monitoring is achieved, but the system becomes vulnerable to connection deterioration between the temperature sensor and controller
Solution Approach 1:
The patent combines the temperature monitoring function with the data driver by integrating the temperature sensor directly into the data driver circuit. This merging eliminates the separate connection path between the temperature sensor and controller, thereby improving reliability by removing a potential failure point while reducing connection complexity.
Solution Approach 2:
The data driver serves as an intermediary component that directly receives temperature data from the temperature sensor and processes it to generate visual feedback. This intermediary role allows the system to monitor temperature without requiring a direct connection to the controller, thus improving reliability by bypassing potential connection deterioration points.
2Loss of information
If temperature data is processed through the controller, then centralized control is maintained, but visual feedback is delayed or lost when connection deteriorates
Solution Approach 1:
The patent segments the temperature monitoring and visual feedback functions from the central controller by implementing them locally within the data driver. This segmentation allows temperature information to be processed and displayed independently, preventing information loss and ensuring rapid local response without waiting for controller processing.
Solution Approach 2:
The data driver is pre-configured with the capability to process temperature data and generate visual feedback independently. This preliminary preparation enables immediate response to temperature changes without requiring real-time controller intervention, thus preventing information loss and improving response speed.
3Ease of operation
If a separate temperature monitoring system is used, then temperature detection is achieved, but the system cannot provide visual feedback when connection to controller is compromised
Solution Approach 1:
The patent merges the temperature sensor, data processing, and visual feedback generation into a single integrated module within the data driver. This integration ensures that visual feedback capability remains operational as long as the local module receives power, without requiring separate connection paths to the controller, thus improving both ease of operation and reliability.
