Dynamic Display Brightness Control for Mobile Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device power management techniques, particularly in controlling display brightness, do not adequately account for user interaction or application states, leading to inefficient power consumption, especially during webpage loading and device application usage.
Innovation Solution
Implementing a method to dynamically control display brightness based on user inputs and application states by monitoring markers indicative of user actions, such as URL requests or content rendering progress, to dim the display during periods of low user interest and restore brightness upon completion or increased interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If display brightness is maintained at high level continuously, then user experience is improved, but battery power consumption increases
Solution Approach 1:
The patent applies dynamics by making the display brightness adjustable and responsive to changing conditions. The system dynamically transitions between high brightness (when user interaction is detected) and low brightness (during loading periods), allowing the display to adapt its illumination intensity based on real-time user engagement levels and application states, thereby resolving the contradiction between maintaining good user experience and reducing power consumption
Solution Approach 2:
The patent changes the brightness parameter of the display based on detected user interaction patterns and application loading states. By monitoring user inputs and adjusting the display brightness parameter accordingly - maintaining high brightness during active interaction and reducing it during passive loading periods - the system optimizes the balance between user experience quality and battery power consumption
2Duration of action of moving object
If display brightness is reduced to save power, then battery life is extended, but user experience deteriorates
Solution Approach 1:
The patent implements periodic action by alternating between high brightness periods (when user interaction is detected) and low brightness periods (during application loading or idle states). This periodic switching ensures that the display provides full brightness when users need it for good user experience, while extending battery life during periods when user engagement is low, thus resolving the contradiction between battery life extension and user experience maintenance
Solution Approach 2:
The system uses feedback from user interaction detection to control display brightness. By monitoring user inputs and application states, the system receives feedback about when users are actively engaged with the device and adjusts brightness accordingly - maintaining high brightness during interaction to preserve user experience while reducing brightness during loading periods to extend battery life
3Adaptability or versatility
If traditional brightness control algorithms are used, then device characteristics are optimized, but user interaction context is ignored
Solution Approach 1:
The patent applies preliminary action by proactively detecting user interaction patterns and application loading states before making brightness adjustments. The system monitors user inputs and application events in advance, preparing to switch brightness levels appropriately - this allows the display to adapt to user context without requiring complex real-time analysis, thereby achieving good adaptability while managing algorithm complexity

AI summary
Systems, methods, and apparatus are herein disclosed for controlling a display brightness based on user action or user interest in the display. In particular, the display brightness can be dimmed upon identification of a first marker indicative of a user action such as a request for a webpage. The brightness of the display can be increased or returned to its original state upon identification of a second marker indicative of completion of a user equipment activity triggered by the user action. In some embodiments, another brightness state between these two can be used as an intermediary and is triggered when a third marker, indicative of a progression of the user equipment activity, is identified.
