Foldable Device Transition Screen Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face a seamless user experience issue due to the time required for redrawing screens when transitioning between folded and unfolded states, leading to delays in displaying the correct screen.
Innovation Solution
The device employs a processor-controlled method to display a transition screen while operations are performed during state changes, and once these operations are complete, it replaces the transition screen with the corresponding screen, optimizing the display process.

Engineering Contradiction Analysis
1Reliability
If the device redraws the screen when transitioning from folded to unfolded state, then the correct screen is displayed, but there is a delay that reduces user experience
Solution Approach 1:
The system performs preliminary actions by displaying a transition screen immediately upon detecting the unfolded state, while simultaneously executing the operations needed to generate the final screen. This preliminary display avoids the blank or delayed period that would otherwise occur while the system prepares the correct screen content.
Solution Approach 2:
A transition screen serves as an intermediary element between the folded and unfolded screen states. This intermediary display maintains visual continuity for the user while the system performs the necessary operations to prepare the final screen, effectively bridging the time gap without compromising display accuracy.
2Ease of operation
If the device displays a transition screen during state change, then user experience is improved, but additional display operations are required
Solution Approach 1:
The system merges the transition screen display operation with the final screen preparation operations by executing both simultaneously. The transition screen is displayed while the system performs the necessary operations to generate the correct screen, combining multiple functions into a coordinated sequence that improves user experience without proportionally increasing complexity.
Solution Approach 2:
The display system operates dynamically by transitioning from a static display approach to a multi-stage dynamic display process. The system adaptively switches between displaying the transition screen and the final screen based on the operational state, creating a fluid user experience that manages complexity through state-based control.

AI summary
An electronic device is provided. The electronic device includes a hinge structure, a first housing, a second housing, a first display, a second display, and a processor. The processor may be set to control the first display to display a first screen of a first application while in a folded state, the first screen corresponding to the first display, control the second display to display a transition screen when unfolding is detected, and control the second display to display a second screen in replacement of the transition screen upon the completion of at least one operation set to be performed in order to display the second screen, corresponding to the second display, of the first application.
