Foldable Display Rotation Control for Flex-Mode Landscape Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices do not provide a landscape mode for displaying content on an external display when partially folded or unfolded, and fail to maintain a lock screen in a landscape mode during inactivity, limiting user experience.
Innovation Solution
An electronic device equipped with a sensor to detect geometric deformation, a processor, and memory to control the display mode based on rotation settings, ensuring a landscape mode is maintained during flex modes and providing a lock screen when the device is inactive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the foldable electronic device is folded to a V-shaped form (flex mode), then the device can be used in compact form, but the screen rotation mode cannot be changed to landscape mode when portrait fixing mode is set
Solution Approach 1:
The patent implements dynamic adjustment of display mode based on the folding state of the device. When the device is in a V-shaped flex mode, the system automatically switches from portrait fixing mode to landscape mode, allowing the display orientation to adapt dynamically to the physical configuration of the device rather than remaining statically fixed.
Solution Approach 2:
The patent changes the display parameter (rotation mode) based on the geometric deformation state of the device. By detecting the folding angle and configuration, the system adjusts the screen orientation parameter from portrait to landscape mode, enabling the display to respond to physical parameter changes in the device structure.
2Ease of operation
If the device maintains portrait fixing mode during flex mode, then the rotation setting is preserved, but the user experience is degraded due to inability to view content in landscape orientation
Solution Approach 1:
The system dynamically adjusts the display mode based on the folding state, allowing the screen to switch between portrait and landscape orientations according to the physical configuration. This dynamic behavior improves ease of operation by enabling users to view content in the appropriate orientation for each flex mode while temporarily suspending the portrait fixing constraint.
Solution Approach 2:
The system provides feedback by automatically switching to landscape mode when detecting V-shaped flex configuration, and returns to portrait mode when unfolded. This feedback mechanism enhances user experience by automatically adapting the display to the optimal orientation without requiring manual user intervention.
3Reliability
If the device does not provide lock screen in landscape mode during flex mode, then the system complexity is reduced, but security and usability are compromised during inactivity
Solution Approach 1:
The lock screen functionality dynamically adapts to the flex mode by switching to landscape orientation when the device is folded into a V-shape. This dynamic adjustment ensures that the lock screen is displayed in the optimal orientation for the current physical configuration, maintaining both security and usability without requiring separate lock screen implementations for different modes.

AI summary
Disclosed is an electronic device comprising: a display, a sensor configured to detect geometric deformation of the electronic device, at least one processor, and a memory operatively connected to the at least one processor and storing at least one application. The memory may include one or more instructions which, when executed, cause the at least one processor to: control the display to display an execution screen of the at least one application on the display in response to execution of the at least one application in the memory; check a rotation mode setting of the electronic device; obtain display characteristic information of the display in response to a geometric deformation event detected by the sensor; determine a display mode of the execution screen based on the display characteristic information and the checked rotation mode setting and map same to the at least one application; and control the display to display the execution screen on the display based on the mapped display mode.
