Display Refresh Rate Control via Brightness Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen refresh rate technologies impair user experience and increase power consumption when display content changes under a certain brightness scenario due to fixed refresh rates.
Innovation Solution
Dynamically adjust the screen refresh rate based on brightness intervals, with each interval corresponding to a specific refresh rate range, ensuring smooth display and reduced power consumption.

Engineering Contradiction Analysis
1Illumination intensity
If the screen refresh rate is increased to improve display smoothness, then the image display quality is improved, but the power consumption of the electronic device is increased
Solution Approach 1:
The patent implements dynamic refresh rate adjustment by dividing the brightness range into multiple intervals and assigning different refresh rate ranges to each interval. The system dynamically selects the appropriate refresh rate based on the current brightness level, transitioning from a static fixed refresh rate to a dynamic adaptive refresh rate that changes with brightness conditions.
Solution Approach 2:
The patent changes the refresh rate parameter based on brightness parameter changes. By establishing a correspondence between brightness intervals and refresh rate ranges, the system adjusts the refresh rate parameter according to the current brightness level, achieving adaptive optimization of both display quality and power consumption.
2Ease of operation
If a fixed screen refresh rate is used to simplify control, then the device complexity is reduced, but the user experience under certain scenarios is impaired
Solution Approach 1:
The patent segments the brightness range into multiple brightness intervals and corresponds each interval to a specific refresh rate range. This segmentation allows the system to manage complexity by dividing the continuous brightness parameter into discrete intervals, each with predefined refresh rate options, thus maintaining control simplicity while improving adaptability.
Solution Approach 2:
The patent applies different refresh rate characteristics to different brightness intervals, creating local optimization. Each brightness interval has its own corresponding refresh rate range tailored to that specific brightness condition, ensuring optimal user experience for each scenario rather than using a one-size-fits-all approach.

AI summary
A control method includes determining a target brightness of a screen, in response to the target brightness being within a target brightness interval, determining a target refresh rate range corresponding to the target brightness interval, and based on the at least two refresh rates included in the target refresh rate range, responding to dynamic refresh rate adjustment when the screen is under the target brightness. A whole brightness range supported by the screen corresponds to at least two brightness intervals. Each brightness interval of the at least two brightness intervals corresponds to a refresh rate range in a one-to-one correspondence, and the refresh rate range includes at least two refresh rates.
