Refresh Rate Setting Apparatus for Jerky Image Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals experience jerky image movement due to varying frame rates of application programs, which existing refresh rate adjustment techniques fail to address effectively, leading to difficulties in maintaining high display quality.
Innovation Solution
A refresh rate setting apparatus that sets the display refresh rate to a first rate of 90 Hz or higher and determines whether it is an integer multiple of the application program's frame rate, adjusting to a second refresh rate if necessary, based on available settings, to ensure optimal alignment with the frame rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the refresh rate of the display is adjusted while the application program is running, then the display quality can be optimized for the application's frame rate, but jerky movement occurs in the displayed image
Solution Approach 1:
The patent applies preliminary action by detecting the frame rate of the application program and setting the display refresh rate to an appropriate value before the application program fully runs. The determination unit checks whether the frame rate is an aliquot of the refresh rate and adjusts the refresh rate in advance, preventing jerky movement from occurring during execution.
Solution Approach 2:
The patent implements feedback by continuously monitoring the frame rate of the application program and adjusting the display refresh rate based on this information. The determination unit receives frame rate information, evaluates whether it matches the current refresh rate requirements, and triggers appropriate refresh rate changes to maintain smooth display without jerky movement.
2Adaptability or versatility
If the refresh rate is set to a high value (90 Hz or higher), then the display can handle high frame rate applications, but the refresh rate may not be an integer multiple of the application's frame rate causing jerky movement
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the display refresh rate parameter based on the application program's frame rate. The second setting unit changes the refresh rate parameter to a value that is an integer multiple of the detected frame rate, ensuring both high performance compatibility and smooth image display without jerky movement.
Solution Approach 2:
The patent implements dynamics by making the refresh rate adjustable and adaptable rather than fixed. The system dynamically determines the appropriate refresh rate based on the running application's frame rate characteristics, allowing the display to optimize its performance for different applications while maintaining image smoothness.
3Manufacturing precision
If the refresh rate is adjusted to match the application's frame rate, then jerky movement is reduced, but the system complexity increases due to additional determination and adjustment mechanisms
Solution Approach 1:
The patent introduces an intermediary component - the determination unit - that mediates between the application program's frame rate requirements and the display's refresh rate capabilities. This intermediary evaluates frame rate information and determines appropriate refresh rate settings, simplifying the overall control logic while achieving smooth image display.

AI summary
A refresh rate setting apparatus for use in a portable terminal, comprises a first setting unit configured to, when an application program is started, set a refresh rate of a display of the portable terminal to a first refresh rate equal to or higher than 90 Hz; a determination unit configured to determine whether the first refresh rate is an integer multiple of a frame rate of the application program; and a second setting unit configured to, in a case where the determination unit determines that the first refresh rate is not an integer multiple of the frame rate, set the refresh rate to a second refresh rate according to whether values settable as the refresh rate include one or more values each equal to an integer multiple of the frame rate.
