Foldable Device Secondary Display Adaptive Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with flexible displays lack dynamic information display capabilities when structurally varied, limiting user interaction and convenience.
Innovation Solution
An electronic device with a hidden display that dynamically displays information based on the exposed area, utilizing a secondary display that adjusts content and brightness according to the device's structural changes, such as folding or bending, through a combination of sensors and user interface management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a flexible display is folded for carrying, then the device becomes portable and compact, but the display area for showing information is reduced or hidden
Solution Approach 1:
The display system is segmented into multiple independent display regions: a first display region on the front surface and a second display region on the back surface. This allows the device to provide display functionality in both folded and unfolded states, resolving the contradiction between portability and display area availability.
Solution Approach 2:
The display functionality is extended to another dimension by placing a display region on the back surface of the device. When the device is folded, the back display region becomes visible and usable, effectively adding a spatial dimension to the display capability that compensates for the reduced front display area.
2Ease of operation
If information is displayed on a hidden display with limited exposed area, then user interaction is maintained in folded state, but the amount of information that can be displayed is limited
Solution Approach 1:
The display content is segmented and distributed across multiple display regions. Simple information such as notifications, time, and basic status can be shown on the hidden back display, while more comprehensive information is displayed on the main front display, optimizing both user interaction in folded state and overall information capacity.
Solution Approach 2:
The hidden display shows a partial set of information necessary for basic user interaction in folded state, rather than attempting to display all possible information. This partial display approach maintains ease of operation when folded while accepting that full information capacity is only available when unfolded.
3Ease of operation
If the display dynamically adjusts based on exposed area, then user convenience is enhanced through adaptive display, but the system complexity increases due to sensors and control mechanisms
Solution Approach 1:
The display system dynamically adapts its behavior based on the device's folded or unfolded state. The controller detects the structural state and automatically adjusts which display region is active and what content is shown, providing user convenience through adaptive display without requiring manual intervention.
Solution Approach 2:
The system uses sensors to detect the device's structural state (folded or unfolded) and provides feedback to the controller, which then adjusts the display configuration accordingly. This feedback mechanism enables automatic adaptive display behavior while keeping the control logic relatively simple and straightforward.

AI summary
A method for displaying information at a foldable electronic device having a secondary display that is exposed when the foldable electronic device is folded, the method comprising: obtaining, by a processor, information associated with an exposure of the secondary display; displaying a first content item on the secondary display based on a size of an exposed area of the secondary display; and updating the secondary display in response to detecting a change in the size of the exposed area of the secondary display.
