Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic brightness algorithms for electronic devices fail to adapt to individual user preferences and varying display scenarios, leading to inconsistent screen brightness experiences, requiring frequent manual adjustments by users.
Innovation Solution
A screen brightness adjustment method that determines a first brightness adjustment rule based on manually-adjusted screen brightnesses corresponding to different ambient light brightnesses in specific display scenarios, such as text reading, video, or game scenarios, using a combination of user-adjusted and preset automatic brightness algorithms to optimize backlight brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional automatic brightness algorithms use a single global offset based on manual adjustment, then the system maintains simplicity in implementation, but the screen brightness becomes inconsistent across different ambient light conditions and display scenarios, requiring frequent user adjustments
Solution Approach 1:
The patent segments the brightness adjustment system by creating separate brightness adjustment rules for different display scenarios (text reading, video, game, etc.). Each scenario has its own adaptive brightness curve based on user preferences specific to that scenario, rather than using a single global offset for all scenarios. This segmentation allows the system to adapt to scenario-specific brightness requirements without increasing overall system complexity.
Solution Approach 2:
The patent implements dynamic brightness adjustment rules that adapt based on multiple factors including ambient light conditions, display scenario, and user preferences. The brightness adjustment is no longer static but dynamically changes according to the current context, reducing the need for frequent manual adjustments while maintaining user experience consistency across varying conditions.
2Adaptability or versatility
If the system applies manual adjustment as a global offset across all ambient light brightnesses, then the implementation remains simple, but the brightness experience becomes inconsistent between bright and dark environments
Solution Approach 1:
The patent applies local quality by creating scenario-specific brightness adjustment characteristics. Each display scenario (text reading, video, game) has its own brightness adjustment curve tailored to user preferences for that specific scenario. This allows the system to maintain reliable and consistent brightness experience within each scenario while adapting to different ambient light conditions, rather than applying a uniform global offset that fails to account for scenario-specific requirements.
Solution Approach 2:
The patent changes the parameters of brightness adjustment by introducing scenario-specific adjustment curves with different characteristics for each display scenario. Instead of using a single global offset parameter, the system now uses multiple parameters including scenario type, ambient light level, and scenario-specific user preferences to determine the appropriate brightness adjustment, thereby improving both adaptability and reliability.
3Adaptability or versatility
If the system uses only preset automatic brightness algorithms without user-specific customization, then the system complexity remains low, but the brightness does not meet individual user requirements in different scenarios
Solution Approach 1:
The patent applies preliminary action by collecting and storing user brightness adjustment preferences in advance for different display scenarios. The system records user manual adjustments across multiple scenarios and uses these pre-collected preferences to generate scenario-specific brightness adjustment curves. This preliminary collection of user preference data enables the system to provide personalized brightness adaptation without requiring complex real-time processing, thereby achieving personalization while managing system complexity.

AI summary
Embodiments of this application provide a screen brightness adjustment method and an electronic device, and relate to the terminal field, to avoid frequent brightness adjustment performed by a user, and improve user experience. The method includes: obtaining an ambient light brightness in a first display scenario, where the first display scenario includes any one of a text reading scenario, a video scenario, or a game scenario; determining a screen backlight brightness in the first display scenario based on the ambient light brightness and a first brightness adjustment rule, where the first brightness adjustment rule is determined based on at least two different ambient light brightnesses in the first display scenario, manually-adjusted screen brightnesses corresponding to the at least two different ambient light brightnesses, and a preset automatic brightness algorithm; and adjusting a screen brightness of the electronic device based on the screen backlight brightness in the first display scenario.
