Screen Brightness Adjustment Using Time-Based Curves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen brightness adjustment methods in smart devices are inadequate as they fail to meet individual user requirements, leading to complicated operations and unsatisfactory user experiences, as they rely solely on ambient light sensors and do not account for varying user perceptions and environmental factors like time, location, and weather.
Innovation Solution
A method and device that determine a screen brightness adjusting curve based on current time, ambient luminance, geographic position, and meteorological data to automatically adjust screen brightness, using multiple curves for different time periods and scenarios to optimize user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If optical sensor is used for monitoring ambient luminance to adjust screen brightness, then the screen brightness adjustment is automated, but the adjusted brightness cannot meet individual user requirements
Solution Approach 1:
The patent applies parameter changes by introducing time-based adjusting curves that modify the relationship between ambient luminance and screen brightness. Different curves are selected based on time periods (daytime, evening, nighttime), allowing the system to adapt brightness settings to both environmental conditions and user preferences at different times, thus resolving the contradiction between automation and user requirement adaptation.
2Adaptability or versatility
If manual brightness adjustment is implemented to meet individual user requirements, then user experience is improved, but the operation becomes complicated
Solution Approach 1:
The patent implements self-service by enabling the system to automatically select appropriate brightness adjusting curves based on time and ambient light conditions without requiring user intervention. The device serves itself by monitoring time, ambient luminance, and selecting the most suitable curve, thereby maintaining user requirement adaptation while eliminating complicated manual operations.
3Adaptability or versatility
If time-based brightness adjusting curves are implemented, then user experience is optimized for different times, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the brightness adjustment system into multiple time-based curves (daytime curve, evening curve, nighttime curve). Each curve represents a segmented approach for different time periods, allowing the system to handle complexity through modular, time-segmented strategies rather than a single complex algorithm.

AI summary
Methods and apparatuses are provided for adjusting screen brightness. The method may include: determining a screen brightness adjusting curve corresponding to current time, and determining current screen brightness according to current ambient luminance and the screen brightness adjusting curve. With the technical solutions provided in the present disclosure, the screen brightness can be adjusted to be most suitable for human eyes according to time; the problem of unsatisfactory screen brightness caused by adjusting a screen into same brightness according to same ambient brightness in different time periods is avoided.
