Solution Overview
Problem
Conventional electronic devices with fixed frame rates struggle to adapt to changing display content and operating environments, leading to suboptimal power consumption and display performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a fixed standard frame rate is used for the display, then the display performance is consistent and reliable, but the power consumption cannot be optimized when display content changes
Solution Approach 1:
The patent implements a variable frame rate display system where the frame rate dynamically adjusts based on the type of content being displayed. The display controller monitors content characteristics (static vs. dynamic) and automatically changes the frame rate accordingly, transitioning from a fixed to a dynamic system that adapts to operational conditions.
Solution Approach 2:
The patent changes the frame rate parameter based on content type detection. When static content is detected, the frame rate is reduced to conserve power; when dynamic content is detected, the frame rate is increased to maintain display quality. This parameter adjustment directly addresses the power consumption vs. adaptability contradiction.
2Use of energy by moving object
If the display frame rate is reduced for static content, then power consumption decreases, but the display cannot respond quickly when content becomes dynamic
Solution Approach 1:
The display controller continuously monitors content characteristics and uses this feedback to adjust the frame rate in real-time. When content transitions from static to dynamic, the feedback mechanism detects the change and immediately increases the frame rate, ensuring quick response while maintaining power efficiency during static periods.
Solution Approach 2:
The system maintains the capability to quickly switch to higher frame rates by keeping the display controller in a ready state that can rapidly adjust parameters. This preliminary preparation ensures that when dynamic content is detected, the frame rate increase occurs without significant delay.
3Measurement precision
If the frame rate is increased for dynamic content, then the perceived display resolution improves, but the power consumption increases
Solution Approach 1:
The system dynamically adjusts the frame rate based on content requirements, using high frame rates only when dynamic content is displayed and low frame rates when static content is displayed. This dynamic adaptation maintains perceived resolution during dynamic content while minimizing power consumption during static content periods.
Solution Approach 2:
The frame rate parameter is changed based on content type detection, increasing the parameter value when high resolution is needed for dynamic content and decreasing it when static content is displayed, thereby optimizing the trade-off between display quality and power consumption.
4Adaptability or versatility
If a user manually selects frame rate, then the user can optimize for specific scenarios, but the user cannot effectively choose frame rate for each changing configuration
Solution Approach 1:
The display controller automatically performs frame rate selection based on content analysis, eliminating the need for manual user input. The system serves itself by monitoring content characteristics and making intelligent frame rate decisions, providing both adaptability and ease of operation simultaneously.
Solution Approach 2:
The system uses feedback from content monitoring to automatically adjust frame rate settings, replacing manual user selection with an automated feedback-driven control mechanism that adapts to changing configurations in real-time.

AI summary
An electronic device may be provided with a display. The display may be a variable frame rate display capable of adaptively adjusting a frame rate at which display frames are displayed in response to information associated with the current state of operation of the device. The information may be gathered using control circuitry in the electronic device. The control circuitry may gather the information for adjusting the frame rate by monitoring the electronic device power supply configuration, other device components, the type of content to be displayed, and user-input signals. The control circuitry may adjust the frame rate based on the gathered information by increasing or decreasing the frame rate. The control circuitry may be formed as a portion of display control circuitry for the device such as a display driver integrated circuit or may be formed as a portion of storage and processing circuitry external to the display.
