Foldable Sub-Display Rotation for Tabletop Viewing Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices face challenges in optimizing screen display orientation based on their posture and angle of folding, particularly when used as table-top devices, leading to suboptimal user experience.
Innovation Solution
The electronic device includes a flexible display and a sensor to detect the degree of horizontality and folding, allowing it to adjust screen display direction based on the device's posture, ensuring optimal viewing in various states, including folded and unfolded configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen display direction is fixed in traditional foldable devices, then the device structure is simple, but the user experience deteriorates when the device is placed in different postures such as table-top mode
Solution Approach 1:
The patent implements dynamic screen orientation adjustment by detecting the device's folding angle and posture through sensors, then automatically rotating the display content to maintain optimal viewing direction. The screen transitions from fixed orientation to dynamically adjustable orientation based on real-time device state, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The system employs sensor feedback mechanisms to continuously monitor the device's folding angle and posture, processing this information to determine the appropriate screen rotation state. This closed-loop feedback system enables the display to adapt automatically to different usage scenarios including table-top mode, handheld mode, and folded configurations without requiring complex manual intervention.
2Ease of operation
If the screen rotates automatically based on device posture, then user experience is improved, but the risk of unintended rotation increases
Solution Approach 1:
The patent implements a preliminary detection phase where the system monitors device posture changes and predicts user intent before executing screen rotation. By analyzing the trajectory and duration of posture changes, the system can distinguish between intentional placement (such as setting the device on a table) and transient movements, thereby preventing unintended rotation while maintaining smooth transition for deliberate actions.
Solution Approach 2:
The system incorporates self-service mechanisms including user preference learning and contextual awareness. It automatically adapts to user habits by learning preferred display orientations in different scenarios and adjusts screen rotation behavior accordingly. The system also considers contextual factors such as current application usage and environmental conditions to make intelligent decisions about when to rotate the display, reducing false positives while maintaining ease of operation.

AI summary
An electronic device is disclosed. The electronic device may identify an orientation of the electronic device as a tabletop state through data. The tabletop state may be a state in which a second housing part is closer to the ground than a first housing part, the second housing part is arranged to be relatively horizontal with respect to the ground, and the angle of the second housing part with respect to the first housing part is within a specified angle range. The electronic device may display the screen in a first direction through a sub-display while the tabletop state is maintained. The electronic device may display the screen in a second direction opposite to the first direction through the sub-display while the electronic device has a state different from the tabletop state.
