Foldable Display Moving Image Control via Fold State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable multi-panel display devices face challenges in effectively controlling the display of moving images based on the device's fold state and position, leading to inconsistent visibility and reduced user engagement due to low visibility at the fold portion.
Innovation Solution
A method for controlling moving images on foldable display devices by acquiring position and fold state information, stopping or reproducing the image based on apparent size, fold angle, and positional relationships with the user, ensuring optimal visibility by adjusting the display position relative to the fold portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the moving image is continuously reproduced on the foldable display device, then the user engagement is improved, but the resource consumption increases and visibility is reduced at folded positions
Solution Approach 1:
The patent applies dynamics by making the moving image reproduction state adaptive rather than static. The system dynamically adjusts between reproduction and stopping based on real-time fold state information and apparent size calculations, allowing the display to respond to changing physical conditions while optimizing resource usage.
Solution Approach 2:
The system implements feedback by continuously monitoring fold state information and apparent size of the moving image, then using this information to control the reproduction state. This closed-loop control ensures that the moving image is reproduced only when visible and stopped when not visible, improving user engagement while reducing unnecessary resource consumption.
2Productivity
If the moving image is reproduced when the display region is folded, then the advertisement effects are enhanced, but the visibility and user engagement are reduced due to low apparent size
Solution Approach 1:
The patent applies parameter changes by using fold state information and apparent size calculations as control parameters. When the apparent size falls below a threshold during folding, the system changes the reproduction state to stopped, preserving advertisement effectiveness while avoiding display when visibility is insufficient.
Solution Approach 2:
The system performs preliminary action by calculating the apparent size based on fold state information before actually reproducing or stopping the moving image. This advance calculation allows the system to proactively adjust the reproduction state to maintain visibility and advertisement effectiveness.
3Use of energy by moving object
If the moving image is stopped when the apparent size is small, then the resource consumption is reduced, but the user engagement may be affected due to frequent stopping and resuming
Solution Approach 1:
The system uses feedback by continuously monitoring fold state information and apparent size to determine when to stop or resume reproduction. This ensures that the moving image is stopped only when genuinely not visible (during folding), minimizing disruptions to user engagement while maximizing resource savings.
Solution Approach 2:
The patent applies dynamics by making the reproduction state adaptive to real-time fold conditions. The system smoothly transitions between reproduction and stopping based on apparent size thresholds, creating a dynamic response that reduces resource consumption without significantly impacting user engagement through frequent interruptions.

AI summary
A moving image control method for controlling display of a moving image on a foldable display device is provided. The moving image control method includes: acquiring moving image position information indicating a position in a display region at which the moving image is displayed; acquiring fold state information indicating a fold state of the foldable display device; and controlling whether the moving image is stopped or reproduced in the display region based on the moving image position information and the fold state information.
