Foldable Display Video Call Target Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible displays do not effectively manage call targets during multilateral video calls, particularly when the display size changes, leading to cluttered and inefficient visual representations.
Innovation Solution
An electronic device with a foldable housing and dual displays, where the processor adjusts the display of call targets based on the device's state, switching from an unfolded to a folded state, using sub-regions on the second display to organize thumbnails of call targets when the number exceeds a reference value, ensuring a compact and readable layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If all call targets are displayed on a single display when the device is folded, then the number of visible call targets is maximized, but the display becomes cluttered and readability deteriorates
Solution Approach 1:
The patent divides the second display into multiple sub-regions (first sub-region, second sub-region, third sub-region) to organize different sets of call targets. This segmentation allows multiple call targets to be displayed simultaneously in an organized manner, resolving the contradiction between maximizing visible call targets and maintaining readability.
2Volume of moving object
If the display size is reduced when folding the device, then the device becomes more compact and portable, but the display area for showing multiple call targets decreases
Solution Approach 1:
The patent utilizes the spatial dimension created by having two separate displays (first display and second display) to overcome the limited display area when folded. By distributing call targets across both displays and using sub-regions on the second display, the system effectively expands the available display area without increasing the physical device size when folded.
3Loss of information
If more call targets are displayed in larger thumbnails, then individual call targets are more recognizable, but fewer call targets can be displayed simultaneously
Solution Approach 1:
The patent applies different thumbnail sizes to different call targets based on their selection status. Selected call targets are displayed with larger thumbnails in the first sub-region for better recognizability, while unselected call targets are displayed with smaller thumbnails in the second and third sub-regions to maximize the number of visible targets. This local differentiation resolves the contradiction between recognizability and quantity.

AI summary
An electronic device is disclosed, including: a housing foldable along at least one axis, a first display disposed on a first surface of the housing, the first display flexible as to switch from an unfolded state to a folded state along the at least one axis, a second display, separate from the first display, disposed on a second surface of the housing opposite to the first surface, and a processor. The processor is configured to: execute a video call including display of a plurality of call targets on the first display, and based on detecting a switch from the unfolded state to the folded state while a number of the plurality of call targets is greater than or equal to a reference value: display a thumbnail of at least one selected call target from among the plurality of call targets in a first sub-region on the second display, and display thumbnails of unselected call targets from among the plurality of call targets in a second sub-region different from the first sub-region on the second display.
