Dynamic Wallpaper Frame Continuity Across Foldable Screen Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dynamic wallpapers on foldable phones fail to provide a continuous dynamic effect during the transition from a small screen to a big screen, disrupting the user experience.
Innovation Solution
A method for displaying a dynamic wallpaper on an electronic device with an adjustable display size, ensuring that the frames of images displayed on the first and second screens are continuous, with the last frame of the first screen seamlessly transitioning to the first frame of the second screen, and the image sequence adjusting based on the hinge angle between display screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If dynamic wallpaper is displayed only on big-screen home screen, then dynamic effect is presented on large display, but continuous dynamic effect cannot be shown during unfolding from small screen to big screen
Solution Approach 1:
The patent applies preliminary action by pre-planning and pre-configuring different wallpaper display modes for different screen states (folded vs. unfolded). The system prepares the wallpaper rendering in advance based on the predicted screen state, ensuring that when transition occurs, the dynamic effect continues seamlessly without interruption or reset, thus maintaining reliability of the dynamic effect during screen size changes.
Solution Approach 2:
The patent implements dynamics by making the wallpaper display adaptive to the changing screen state. The wallpaper rendering is dynamically adjusted based on whether the screen is folded or unfolded, with the system continuously monitoring screen state and smoothly transitioning between different display modes. This dynamic adaptation ensures continuous dynamic effect while accommodating varying display sizes.
2Adaptability or versatility
If screen size is adjusted during unfolding, then display flexibility is improved, but user experience is disrupted due to lack of continuous dynamic effect
Solution Approach 1:
The patent applies universality by creating a unified wallpaper display system that functions across multiple screen states (both folded and unfolded modes). The same wallpaper resource is universally rendered with appropriate adjustments for each state, eliminating the need for separate wallpaper files or manual user configuration. This multi-functional approach ensures seamless user experience during screen size adjustments while maintaining adaptability to different display configurations.

AI summary
Embodiments of this application relate to the field of display technologies, and disclose a method for displaying a dynamic wallpaper and a related device, to resolve a problem that a dynamic wallpaper does not present a continuous dynamic effect during switching from a small screen to a big screen. A specific solution is applied to an electronic device and includes: displaying a user interface on a first screen, displaying at least one frame of continuous image of the dynamic wallpaper on the first screen, switching to a second screen for displaying the user interface, and displaying at least one frame of continuous image of the dynamic wallpaper on the second screen. Because a first frame of image displayed on the second screen is a last frame of image displayed on the first screen or a frame after a last frame of image displayed on the first screen, the at least one frame of continuous image of the dynamic wallpaper displayed on the first screen is continuous with the at least one frame of continuous image of the dynamic wallpaper displayed on the second screen. Therefore, the dynamic wallpaper presents a continuous dynamic effect during switching from the first screen to the second screen.
