Flexible Display Stress-Based UI Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face degradation in display quality due to accumulated pressure from frequent touch inputs, particularly in areas that receive a high volume of touches.
Innovation Solution
An electronic device is designed with a display that includes a target area divided into multiple unit areas, a touch circuit to sense touch inputs, and a processor that calculates stress values for each unit area and adjusts the position of graphic user interfaces or touch sensing parameters based on these stress values to distribute pressure more evenly.

Engineering Contradiction Analysis
1Productivity
If touch inputs are concentrated on specific areas of the display, then user interaction efficiency is improved, but display quality degradation occurs due to accumulated pressure
Solution Approach 1:
The system dynamically adjusts the position of graphic user interface elements based on real-time stress value calculations. When a particular area accumulates excessive touch pressure, the system automatically relocates interactive elements to different areas, making the UI layout adaptive and dynamic rather than static, thereby distributing wear across the display surface while maintaining interaction efficiency
Solution Approach 2:
The system changes the positional parameters of graphic user interface elements based on stress distribution analysis. By calculating stress values for different display areas and adjusting UI element positions accordingly, the system modifies the spatial parameters of the interface to avoid high-stress regions, resolving the contradiction between interaction efficiency and display durability
2Speed
If the same area of the display is used for frequent touch inputs, then operational speed is improved, but the display lifespan is reduced due to pressure accumulation
Solution Approach 1:
The system performs preliminary stress analysis and proactively relocates graphic user interface elements before significant display degradation occurs. By continuously monitoring stress values and preemptively adjusting UI positions to lower-stress areas, the system extends display lifespan while maintaining operational speed through seamless transitions
Solution Approach 2:
The system implements a feedback mechanism where stress values from touch inputs are continuously measured, analyzed, and used to adjust UI element positions. This closed-loop control ensures that high-frequency touch areas are automatically redistributed to less worn areas, balancing operational speed with display longevity through real-time feedback-driven adaptation

AI summary
An electronic device may include a display, a touch circuit, and a processor. The display may include an area visually exposed to an outside of the electronic device is capable of being changed between a first state and a second state. When an identified first stress value of a first unit area, among a plurality of unit areas, is greater than a first threshold value, based on a graphic user interface to be displayed, the display may be controlled to display a graphic user interface in a first area including the first unit area in a second area excluding the first unit area, to reduce pressure to the first unit area.
