Flexible Display Screen Switching via Size Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays lack an efficient method for users to switch between multiple applications or screens, often requiring inconvenient steps such as swiping sideways.
Innovation Solution
An electronic device with a flexible display that allows users to expand or reduce the viewable display region as a gesture for switching screens, using sensors to detect changes in display size and a processor to manage screen transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users switch between multiple applications or screens using conventional methods (swiping sideways), then screen switching functionality is provided, but user convenience is reduced and operation becomes complex
Solution Approach 1:
The patent applies the dynamics principle by enabling the flexible display to physically change its size and shape through expansion and contraction movements. The display region can dynamically transition between different sizes, and this physical dynamic change is used to trigger screen switching operations, replacing static navigation gestures with dynamic physical transformations that are more intuitive and easier to operate.
2Productivity
If the flexible display size is changed to enable screen switching, then screen transition functionality is improved, but display stability during the transition process is compromised
Solution Approach 1:
The patent applies preliminary action by displaying a list of selectable items in advance during the display expansion or contraction process. Before the screen switching is finalized, the system prepares and presents available options to the user, allowing them to select their desired screen. This preliminary display of options ensures stable and controlled transitions while maintaining productivity.
3Adaptability or versatility
If a list with selectable items is displayed during display size change, then user selection capability is enhanced, but display region utilization is reduced
Solution Approach 1:
The patent applies partial action by displaying the list of selectable items in a partial region of the flexible display rather than occupying the entire display area. The list is shown in a portion of the expanded or contracted display region, allowing the remaining area to be utilized for other purposes or to maintain the original screen content, thus balancing selection capability with display region utilization.

AI summary
According to certain embodiments, an electronic device performs: displaying a first screen lay; sensing a change in the size of the viewable portion of a flexible display through at least one sensor; displaying a list comprising at least one selectable item in at least a partial region of the flexible display during the changing of the size of the viewable portion of the flexible display; detecting that the changing of the size of the viewable portion of the flexible display has stopped; and if so, displaying the first screen corresponding to the viewable portion of the flexible display with the changed size; and in response to returning of the size of the viewable portion of the flexible display to an original size without completing the change in the size of the viewable portion of the flexible display, displaying a second screen corresponding to a selectable item on the viewable portion of the flexible display having the original size.
