Bending-Aware Screen Pre-Rendering for Foldable Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices experience delays in display transitions due to the change in state, such as when folding or unfolding, leading to a suboptimal user experience.
Innovation Solution
The electronic device analyzes context information to determine whether to render a second execution screen in advance, controlling the quality of content based on the angle change between housing structures, ensuring seamless transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the display waits to render the second execution screen after state change is detected, then the device complexity is reduced, but the transition time increases causing display operation delay
Solution Approach 1:
The system performs preliminary actions by analyzing context information and determining whether to render the second execution screen in advance before the actual display transition occurs. This pre-computation of transition requirements eliminates the delay between state change detection and screen rendering, as the display system already knows what needs to be shown when the user views the display after folding/unfolding.
Solution Approach 2:
The system uses feedback from context information analysis to dynamically adjust the rendering strategy. By continuously monitoring the folding state and analyzing contextual cues, the system determines the optimal timing for screen transitions, creating a closed-loop control mechanism that minimizes perceived transition time while managing processing resources efficiently.
2Speed
If the display renders the second execution screen immediately after state change, then the transition speed is improved, but the content quality may be compromised due to timing constraints
Solution Approach 1:
The system performs preliminary analysis of context information to determine the appropriate rendering strategy before the actual display transition. This allows the system to pre-prepare the second execution screen with optimal quality settings based on predicted user needs, ensuring both fast transition and high content quality by knowing in advance what needs to be rendered and at what quality level.
Solution Approach 2:
The system dynamically adjusts content rendering quality based on real-time conditions. By analyzing the folding state and contextual information, the system can adaptively control the quality of content displayed, ensuring seamless transitions while maintaining appropriate visual quality for different usage scenarios such as folded vs. unfolded states.

AI summary
An electronic device and method are disclosed. The device includes a foldable housing including a hinge connecting a first and second housing, a first bendable display, a second display oriented facing the first display, at least one sensor for detecting the bending, a memory and a processor. The processor implements the method, including: detecting bending by the sensor while displaying an application,, determining to pre-generate another screen of the application based on the bending angle, pre-generating the second execution screen before the change in the angle is reaches a threshold value, and active a deactivated display and display the second execution screen on the activated display when the angle surpasses the predetermined threshold value.
