Display Apparatus Dynamic Refresh Rate Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of display apparatuses has lagged behind graphic processors in terms of refresh rate capabilities, leading to potential suboptimal image display quality, even when the source apparatus is capable of processing high-quality game content, due to differences in replacement cycles and technological advancements.
Innovation Solution
A display apparatus that dynamically adjusts its refresh rate by switching between a higher and a lower refresh rate based on usage time, transmitting this information to the source apparatus to ensure the image is displayed at a rate compatible with the display's capabilities, thereby preventing overload and maintaining image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display apparatus operates at a high refresh rate to match the source apparatus capability, then the image quality is improved, but the display apparatus may be overloaded and become unstable
Solution Approach 1:
The display apparatus dynamically adjusts its refresh rate based on usage time and content type. The processor monitors the elapsed time since the last refresh rate change and automatically switches between first refresh rate (higher) and second refresh rate (lower) to prevent overload while maintaining image quality when needed.
Solution Approach 2:
The system changes the refresh rate parameter from a fixed value to a dynamically adjustable value. The processor modifies the refresh rate based on elapsed time thresholds, switching between higher and lower refresh rates to balance image quality and system stability.
2Manufacturing precision
If the display apparatus uses a higher refresh rate, then the image display quality is improved, but the energy consumption increases
Solution Approach 1:
The display apparatus periodically switches between higher and lower refresh rates based on elapsed time intervals. This periodic adjustment allows the system to consume less energy on average while still providing high-quality display during specific periods when needed.
Solution Approach 2:
The refresh rate parameter is dynamically changed between higher and lower values based on usage time, allowing the system to optimize energy consumption while maintaining the capability to display high-quality images when required.
3Adaptability or versatility
If the display apparatus operates beyond its supported refresh rate range, then the adaptability is improved, but the reliability decreases
Solution Approach 1:
The display apparatus dynamically adjusts its operational refresh rate based on elapsed time and usage conditions. By monitoring how long the system has been operating at a higher refresh rate, the processor automatically switches to a lower refresh rate to prevent overload, thus maintaining reliability while extending operational adaptability.
Solution Approach 2:
The system proactively switches to a lower refresh rate before overload occurs by monitoring elapsed time. This preventive measure cushions against potential system instability by reducing the refresh rate before the display apparatus becomes overloaded.
