Display Frequency Synchronization for Terminal Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies face issues with frame loss, repeated frames, or freeze due to mismatched refresh frequencies of multiple to-be-displayed information on a display screen, leading to poor user experience and increased power consumption.
Innovation Solution
An information display method that determines the display frequency of a display screen by obtaining the type of each to-be-displayed information, calculating a common multiple of their refresh frequencies when necessary, and adjusting the display frequency to ensure smooth and efficient display, prioritizing dynamic content and balancing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display screen uses a fixed refresh frequency for all information, then the display process is simple, but frame loss and repeated frames occur due to mismatched refresh frequencies of different information types
Solution Approach 1:
The patent applies dynamics by making the display frequency adjustable rather than fixed. The processor dynamically determines the display frequency based on the refresh frequencies of different information types, allowing the system to adapt to varying content requirements and eliminate frame loss while managing complexity through intelligent control.
Solution Approach 2:
The patent changes the parameter of display frequency from a static value to a variable that is calculated based on the least common multiple of different refresh frequencies. This parameter change enables the display to synchronize with multiple information sources having different refresh rates, resolving the frame loss issue without requiring complex hardware modifications.
2Reliability
If the display frequency is increased to show all information smoothly, then frame loss is reduced, but power consumption increases
Solution Approach 1:
The patent optimizes the display frequency parameter by calculating it as the least common multiple of the refresh frequencies of different information types. This approach ensures that all information is displayed smoothly without frame loss while avoiding unnecessary increases in power consumption that would result from using a uniformly high refresh rate for all content.
Solution Approach 2:
The system dynamically adjusts the display frequency based on the specific refresh rates of the information being displayed. By making the frequency adaptive rather than fixed at a high constant value, the system maintains display continuity for all information types while optimizing power consumption according to the actual content requirements.
3Adaptability or versatility
If different refresh frequencies are used for different information types, then each information type is displayed optimally, but the display screen experiences frame loss and freeze due to frequency mismatch
Solution Approach 1:
The patent resolves the frequency mismatch issue by changing the display frequency parameter to match the least common multiple of all individual refresh frequencies. This allows the system to maintain different refresh rates for different information types while ensuring that the display screen synchronizes properly, eliminating frame loss and freeze phenomena.
Solution Approach 2:
The patent introduces an intermediary calculation (least common multiple) that acts as a bridge between different refresh frequencies. This intermediary value serves as a unified display frequency that accommodates multiple information types with different refresh rates, ensuring stable display operation without sacrificing the adaptability to different content types.
