Solution Overview

Problem

Electronic devices face a trade-off between optimal user experience and battery life due to varying power consumption associated with different screen refresh rates for different applications, particularly in devices with limited battery capacity.

Innovation Solution

The electronic device dynamically adjusts the screen refresh rate based on factors such as application type, user input, sensor data, and battery power levels, using a refresh rate component to autonomously switch between refresh rates to balance user experience and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a higher screen refresh rate is used to improve user experience for applications like video streaming and gaming, then visual performance and user experience are enhanced, but power consumption increases and battery life decreases

Engineering Contradiction:
Improveuser experienceVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the screen refresh rate based on the running application. When a video streaming or gaming application is detected, the refresh rate is increased to enhance visual performance. When such applications are not running, the refresh rate is reduced to conserve power. This dynamic adjustment resolves the contradiction by making the refresh rate adaptive rather than fixed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameter (refresh rate) of the screen based on the application context. By monitoring which application is currently executing and adjusting the refresh rate parameter accordingly, the system optimizes both user experience and power consumption. This parameter change strategy allows the system to achieve high refresh rates only when necessary for specific applications.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the screen refresh rate is increased to enhance visual performance for specific applications, then user experience improves, but battery life is reduced due to higher power consumption

Engineering Contradiction:
Improvevisual performanceVSAvoidbattery life
Core Design Contradiction:
ProductivityVSDuration of action of moving object

Solution Approach 1:

The system implements dynamic refresh rate adjustment that responds to application context. The refresh rate component continuously monitors the running application and adjusts the screen refresh rate in real-time. This dynamic behavior allows the system to provide high visual performance only when a relevant application is active, thereby preserving battery life during normal operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs parameter changes by modifying the screen refresh rate based on application type. When video streaming or gaming applications are detected, the refresh rate parameter is increased to enhance visual performance. Otherwise, the parameter is reduced to extend battery life, thus resolving the contradiction between visual performance and battery duration.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If a fixed high refresh rate is maintained to ensure optimal user experience across all applications, then user experience is consistently improved, but power consumption increases unnecessarily for applications that do not require high refresh rates

Engineering Contradiction:
Improveuser experienceVSAvoidunnecessary power consumption
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The system changes the screen refresh rate parameter dynamically based on the running application. Instead of maintaining a fixed high refresh rate, the system adjusts the parameter to match the requirements of the current application. This eliminates unnecessary power consumption for applications that do not benefit from high refresh rates while maintaining optimal user experience when needed.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The refresh rate component autonomously adjusts the screen refresh rate based on application context without requiring user intervention. The system self-regulates the refresh rate to match application requirements, thereby avoiding unnecessary energy loss while maintaining optimal performance when needed.

Inventive Principle:
Principle #25Self-service

AI summary

Methods, systems, and devices that support a dynamic screen refresh rate are described. An electronic device may dynamically (e.g., autonomously, while operating) adjust the rate at which a screen is refreshed, such as to balance considerations such as user experience and power consumption by the electronic device. For example, the electronic device may use an increased refresh rate when executing applications for which user experience is enhanced by a higher refresh rate and may use a decreased refresh rate when executing other applications. As another example, the electronic device may use different refresh rates while executing different portions of the same application, as some aspects of an application (e.g., more intense portions of a video game) may benefit more than others from a higher refresh rate. The electronic device may also account of rother factors, such as battery level, when setting or adjusting the refresh rate of the screen.
