Foldable Display Image Continuity via Hinge Angle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with multiple screens face issues of reduced visibility due to bending between screens at certain open-close angles, causing motion sickness when users scroll images, as existing technologies transform images for each screen separately rather than maintaining a continuous plane image.
Innovation Solution
A display device with a plurality of cases having an opening/closing mechanism, an open-close angle detector, and a controller that transforms images based on detected angles to ensure they are recognized as a continuous plane image, preventing bending and aligning user manipulation and visual sensations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If images are transformed for each screen separately, then image display flexibility is improved, but visibility and user comfort deteriorate due to bending between screens
Solution Approach 1:
The patent merges the image transformation operations across multiple screens into a unified continuous plane image. Instead of transforming images independently on each screen, the system combines them to form a single continuous visual field that spans across all screens, eliminating the bending effect at hinge boundaries and improving visibility and user comfort.
2Area of stationary object
If multiple displays are used to increase screen real estate, then display area is improved, but image continuity deteriorates due to hinge bending
Solution Approach 1:
The patent addresses the image continuity problem by transforming the spatial arrangement of images across screens. It maps the sequential image data onto a continuous coordinate system that accounts for the physical hinge angle, effectively creating a virtual continuous plane that maintains image continuity even when screens are bent at various angles.
3Volume of moving object
If screens are bent at certain open-close angles, then device compactness is improved, but user comfort deteriorates due to motion sickness
Solution Approach 1:
The patent dynamically changes the image transformation parameters based on the detected hinge angle. As the device transitions between open and closed states, the system adjusts the transformation matrix to maintain proper image orientation and continuity, preventing the disorientation and motion sickness caused by fixed transformation parameters during device movement.
