Foldable Display Screen Mode and Gap Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable Information Handling Systems (IHS) face challenges in determining optimal screen modes and display configurations based on the angle of folding, leading to potential content distortion and usability issues when folded, as existing technologies lack efficient methods to adapt display settings dynamically with posture changes.
Innovation Solution
A foldable IHS with a logic unit and processor that determines the posture based on the angle of the display fold, splits the display into screen portions, and adjusts the content orientation and gap width between these portions, allowing for dynamic adaptation of screen modes and minimizing content distortion by adjusting the gap width based on the folding angle and posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is folded at different angles, then the IHS can be used in various postures (portability improved), but content distortion and usability issues occur (display quality deteriorates)
Solution Approach 1:
The system dynamically adjusts screen mode and gap width based on the detected folding angle and posture. The processor continuously monitors posture changes and modifies display parameters in real-time, transitioning between single-screen mode, dual-screen mode, and gap-adjusted modes to maintain content accuracy across varying fold angles.
Solution Approach 2:
The patent changes display parameters (screen mode and gap width) based on the folding angle. When the fold angle exceeds a threshold, the system switches to dual-screen mode with an increased gap width to prevent content distortion. This parameter adjustment resolves the contradiction by adapting display characteristics to the current folding state.
2Manufacturing precision
If a gap is displayed along the fold to separate screen portions, then content distortion is reduced (display quality improved), but the visual continuity is broken (aesthetics deteriorates)
Solution Approach 1:
The gap width is dynamically adjusted based on the folding angle. When folded flat, the gap is minimal or invisible, maintaining visual continuity. When folded at angles exceeding the threshold, the gap width increases to prevent content distortion, thus dynamically balancing aesthetics and display accuracy.
Solution Approach 2:
The system changes the gap width parameter based on the detected posture. In dual-screen mode, the gap width is increased to separate screen portions and prevent distortion. The processor automatically adjusts this parameter to optimize both visual appearance and content accuracy for the current folding state.
3Ease of operation
If the screen mode is changed based on folding angle, then display optimization is achieved (usability improved), but the system complexity increases (control mechanism complexity)
Solution Approach 1:
The system uses self-service by leveraging the existing hinge angle sensor to automatically determine posture and trigger appropriate screen modes. The processor autonomously detects folding angle changes and switches between single-screen and dual-screen modes without user intervention, simplifying operation while managing complexity through automated control.
Solution Approach 2:
The system implements feedback by continuously monitoring the hinge angle sensor and using this information to adjust screen mode and gap width. The processor receives feedback on the current folding state and automatically modifies display parameters to optimize usability, creating a closed-loop control system that balances complexity and ease of operation.

AI summary
An Information Handling System (IHS) includes a foldable display and is configured to determine a posture of the IHS based on the angle that the display is folded. The folded display is divided into first and second screen portions. Changes in the posture of the IHS are detected and the content and orientation of the content to display in the respective screen portions is determined. A gap is displayed along the fold of the foldable display, where the gap separates the screen portions along the fold. The width of the gap separating the screen portions may be determined based on the angle that the foldable display is folded and/or based on various additional aspects of the current posture of the IHS.
