Foldable Display Switching Based on Face-Down Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face challenges in optimizing display usage when the main display is facing the ground, leading to inefficiencies in power consumption and usability.
Innovation Solution
A method and device that activate a secondary display when the main display is facing downwards, utilizing sensors to determine the device's orientation and deactivate the main display, thereby reducing power consumption and enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the main display is activated when the device is unfolded and turned over, then the display area is maximized, but power consumption increases
Solution Approach 1:
The system dynamically switches between main display and sub-display based on device orientation detected by sensors. When the device is unfolded and turned over (main display facing ground), the system automatically activates the sub-display instead, creating a dynamic adaptation to usage conditions that reduces power consumption while maintaining display functionality.
2Use of energy by moving object
If the main display is deactivated when facing the ground, then power consumption is reduced, but the display functionality is lost
Solution Approach 1:
The system implements multi-functionality by enabling the sub-display to serve as the active display when the main display is inactive (facing ground), and vice versa. This universal approach ensures that display functionality is maintained across different device orientations and usage scenarios, with either display capable of fulfilling the user interface role.
3Duration of action of moving object
If the sub-display is used instead of the main display, then power consumption is reduced and usage time is extended, but the display area is reduced
Solution Approach 1:
The system applies local quality by using the appropriately sized display for the current usage context. The sub-display, being smaller, consumes less power and is sufficient for many tasks when the device is in tablet mode or turned over. The system selectively activates the sub-display in these specific local conditions rather than always using the largest display, optimizing the balance between display area and power consumption for each usage scenario.

AI summary
The present disclosure can include a method and a device in which the instructions, when executed by the at least one processor, individually and/or collectively, cause the foldable electronic device to: acquire sensing data from a sensor module in an unfolded state of a foldable electronic device in which one surface of a first housing and one surface of a second housing are arranged to be oriented in a same direction; determine, based on the sensing data, whether the foldable electronic device corresponds to a designated condition; and based on the foldable electronic device corresponding to the designated condition, deactivate a first display and activate a second display.
