Rollable Display Wallpaper Preview for Expandable Screen States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with expandable displays fail to adapt wallpaper configurations to changes in screen size due to fixed display settings, lacking intuitive and adaptive user interface solutions for expanded or contracted states.
Innovation Solution
An electronic device with a rollable display and processor capabilities that dynamically configure and display preview images for each display area, allowing user input to select recommended objects and adjust wallpaper accordingly, enhancing usability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wallpaper is provided based on an initially configured image in conventional electronic devices, then the wallpaper setting process is simple, but the wallpaper does not adapt to changes in display size when the screen is expanded or contracted
Solution Approach 1:
The wallpaper configuration system dynamically adapts to different display states by detecting whether the display is expanded or contracted and automatically selecting appropriate wallpaper image areas. The processor identifies the current display state and configures the wallpaper accordingly, making the system responsive to real-time changes without requiring manual user intervention for each state transition.
Solution Approach 2:
The system provides preview images showing different wallpaper configurations based on the current display state. Users can see how the wallpaper will appear in both expanded and contracted states before final selection, allowing them to make informed decisions. This feedback mechanism ensures the wallpaper adapts correctly to display size changes while maintaining user control.
2Manufacturing precision
If a single wallpaper image is used for both expanded and contracted display states, then the configuration process is simple, but the visual quality and appropriateness of the wallpaper deteriorates in one or both states
Solution Approach 1:
The wallpaper configuration is segmented into different image areas corresponding to different display states. The processor identifies and selects appropriate portions of the wallpaper image based on whether the display is expanded or contracted. This segmentation allows optimal image quality for each state while maintaining a unified wallpaper configuration process.
Solution Approach 2:
Different regions of the wallpaper image are optimized for different display states. The system applies local quality adjustments by selecting specific image areas that best suit each display configuration, ensuring high visual quality in both expanded and contracted states without requiring completely separate wallpaper files.
3Area of moving object
If the display size is expanded or contracted, then the electronic device provides more or less screen real estate, but the conventional wallpaper setting does not recognize or adapt to this state change
Solution Approach 1:
The wallpaper configuration system dynamically responds to display state changes by detecting whether the display is expanded or contracted and automatically adjusting the wallpaper image area selection. This dynamic adaptation ensures the wallpaper always appears appropriately sized and positioned regardless of the current display state.
Solution Approach 2:
The system changes wallpaper configuration parameters based on display state. When the display expands or contracts, the processor modifies the selected image area parameters to match the new display dimensions, ensuring the wallpaper maintains appropriate visual proportions and coverage in both states.
