Foldable Device Multi-Window Screen Division Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with multi-window capabilities do not effectively adapt to the unique screen features and folding mechanisms of foldable devices, leading to unsuitable display configurations and user inconvenience when folding or unfolding.
Innovation Solution
A foldable electronic device with a body comprising rotating portions and a display divided into areas, where the processor adjusts the screen division based on the device's folded or unfolded state, allowing for flexible multi-window operations by changing the division line direction in response to user input and orientation changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional multi-window method divides display by comparing width and height is applied to foldable devices, then multi-window functionality is achieved, but the screen configuration becomes unsuitable for foldable device features and user convenience
Solution Approach 1:
The patent implements dynamic screen division that automatically adapts to the foldable device's state (folded or unfolded). When the device is unfolded, the display is divided into multiple regions (first display area and second display area) to support multi-window operations. When folded, the screen division adjusts to accommodate the changed geometry. This dynamic adaptation ensures optimal multi-window configuration regardless of device state, resolving the contradiction between adaptability and user convenience.
Solution Approach 2:
The system changes key parameters including division line orientation (parallel to rotation axis when unfolded), display area allocation, and window placement based on device state. These parameter changes enable the multi-window system to adapt to different geometric configurations, maintaining usability whether the device is folded or unfolded.
2Device complexity
If screen division is based on fixed width/height comparison, then simple multi-window layout is achieved, but rapid screen configuration changes during folding/unfolding become inconvenient
Solution Approach 1:
The system pre-defines division line orientation rules based on device state. When unfolded, the division line is predetermined to be parallel to the rotation axis, optimizing the use of both display areas. This preliminary configuration strategy avoids complex real-time calculations during state transitions, maintaining operational convenience while adapting to geometric changes.

AI summary
An electronic device includes a body including a first portion and a second portion, a display including a first display area and a second display area, and a processor embedded inside the body. The first portion and the second portion rotate about a rotation axis. The first display area is disposed in the first portion. The second display area is disposed in the second portion. The processor is configured to execute a plurality of applications in the first display area by a first division line in a state where the body is folded by rotation of the first portion and the second portion and to execute the plurality of applications in the first display area and the second display area by a second division line parallel to the rotation axis in a state where the body is unfolded by the rotation of the first portion and the second portion.
