Dynamic Screen Resolution Adjustment for Battery and Flicker Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices lack the ability to dynamically change screen resolution based on the device's state or the type of application being executed, leading to inefficiencies in battery life and storage usage, and often result in visual disruptions like screen flicker during resolution changes.
Innovation Solution
An electronic device with a processor that adjusts screen resolution and system resource performance based on the device's state and application type, including converting data for the new resolution and notifying or resetting application processes to maintain continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If screen resolution is changed dynamically based on device state, then battery life is extended and storage is freed, but screen flicker occurs and visual continuity is disrupted
Solution Approach 1:
The system performs preliminary actions by resetting or notifying application processes before the actual resolution change takes effect. This preparatory step ensures that applications are ready for the resolution transition, preventing visual disruptions and maintaining screen output continuity while enabling dynamic resolution adjustment for battery optimization.
Solution Approach 2:
The system uses feedback mechanisms by detecting device states (battery level, storage status, application type) and adjusting resolution accordingly. The processor continuously monitors system conditions and dynamically changes resolution to optimize battery life while maintaining visual continuity through coordinated process management.
2Productivity
If screen resolution is changed dynamically based on device state, then system resource efficiency is improved, but device complexity increases
Solution Approach 1:
The processor performs multiple functions by combining resolution adjustment, application process management, and system state monitoring into a single integrated system. This multi-functional approach improves system resource efficiency without proportionally increasing device complexity, as the same processor handles both display control and application coordination.
Solution Approach 2:
The system changes operational parameters dynamically by adjusting resolution based on device state and application type. The processor modifies display parameters (resolution, refresh rate) and application process states in coordination, achieving improved resource efficiency through parameter optimization rather than hardware complexity increases.
3Use of energy by moving object
If screen resolution is changed dynamically based on application type, then battery life is extended, but visual effects and UI consistency are compromised
Solution Approach 1:
The system applies local quality by resetting or notifying specific application processes selectively based on their type and state. Instead of uniformly handling all applications, the processor tailors the process management approach to each application's characteristics, maintaining UI consistency within specific application contexts while enabling resolution changes for battery optimization.
