Dynamic Refresh Rate Adjustment via Sliding Speed Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the refresh rate of electronic devices fail to effectively reduce power consumption, as they either maintain high refresh rates continuously or reduce them only after a specified duration without considering the sliding speed of page elements, leading to inefficient power management.
Innovation Solution
A method that dynamically adjusts the refresh rate of electronic devices based on the sliding speed of page elements, where the sliding speed is used to determine a candidate refresh rate, which is then applied to adjust the current refresh rate, thereby optimizing power consumption by matching it with the device's capabilities and usage patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the refresh rate is increased to improve image smoothness, then the image quality is improved, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by making the refresh rate adjustable and adaptive rather than fixed. The system dynamically changes the refresh rate based on real-time sliding speed detection, allowing the display to transition between different refresh rate states (e.g., 60Hz, 90Hz, 120Hz) to match user interaction intensity, thus resolving the contradiction between maintaining high image quality and reducing power consumption
Solution Approach 2:
The patent changes the refresh rate parameter based on sliding speed thresholds. When sliding speed exceeds a threshold, the system switches to a higher refresh rate to maintain smooth visual feedback; when sliding speed is below the threshold, the system reduces the refresh rate to save power. This parameter adaptation directly addresses the contradiction by adjusting image smoothness according to actual usage needs
2Stability of the object's composition
If the refresh rate is continuously maintained at a high level to ensure smooth display, then the image quality is maintained, but the power consumption increases
Solution Approach 1:
The patent implements periodic detection of sliding speed and periodic adjustment of refresh rate. Instead of continuously maintaining high refresh rate, the system periodically monitors user interaction (sliding gestures) and adjusts the refresh rate accordingly. This periodic action allows the display to return to lower power states during idle periods while maintaining high quality during active interaction, resolving the contradiction between continuous high display quality and power consumption
3Use of energy by moving object
If the refresh rate is reduced to lower power consumption, then the power efficiency is improved, but the image smoothness deteriorates
Solution Approach 1:
The patent uses feedback by detecting sliding speed and using this information to control refresh rate adjustments. The system continuously monitors user interaction intensity through sliding speed measurement and provides appropriate refresh rate feedback - increasing refresh rate when fast sliding is detected to maintain smoothness, and reducing refresh rate during slow or no sliding to save power. This closed-loop feedback mechanism resolves the contradiction by ensuring image smoothness is maintained only when actually needed

AI summary
A refresh rate adjusting method, includes: obtaining a sliding speed of a page element in a display page of an electronic device; determining a candidate refresh rate corresponding to the page element according to the sliding speed of the page element, the sliding speed being directly proportional to the candidate refresh rate; and adjusting a current refresh rate of the electronic device according to the candidate refresh rate.
