Display Burn-in Reduction via Dynamic Screen Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Burn-in occurs in electronic device displays when the same screen is continuously outputted without change, especially when the operating system does not allow User Interface modifications, leading to pixel burnout and image sticking.
Innovation Solution
A method and electronic device that detect changes in the screen output and modify it when no user activity is detected, applying techniques such as dimming, blurring, or screen savers to reduce burn-in, even when the operating system restricts UI changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the same screen is continuously output through a display without any change, then the operating system maintains a stable user interface, but burn-in occurs by which a cell of a predetermined pixel on the display is burned out and image sticking remains
Solution Approach 1:
The patent applies dynamics by making the screen content changeable rather than static. The processor dynamically modifies the screen content based on detection of user activity or passage of time, transforming the display from a fixed state to an adaptive state that prevents burn-in while maintaining operational stability
Solution Approach 2:
The patent changes parameters of the screen content such as brightness, color, or image patterns. By modifying these parameters over time or based on user activity detection, the display maintains stability in terms of functionality while preventing pixel burnout through parameter variation
2Ease of operation
If the operating system does not allow changing a user interface, then the user interface remains consistent and easy to use, but the probability of burn-in increases
Solution Approach 1:
The patent segments the screen into multiple regions or layers, where certain areas maintain static content for user interface consistency while other areas dynamically change to prevent burn-in. This allows the UI to remain consistent and easy to use while introducing necessary variations to reduce burn-in probability
Solution Approach 2:
The patent introduces an intermediary processing layer between the operating system and the display. This intermediary (the processor) detects user activity and modifies screen content parameters without requiring changes to the operating system itself, thus maintaining UI consistency while reducing burn-in through intermediate content adjustment

AI summary
An embodiment of this disclosure provides a method for reducing burn-in of a display. A burn-in reducing method may include outputting a first screen through a first display. The method also includes outputting a second screen through a second display of which a connection is detected. The method also includes determining whether a change occurs in the first screen that is output through the first display while the connection of the second display is detected. The method also includes modifying and outputting the first screen through the first display based on a result of the determination.
