Flexible Display Input Continuity Across Fold State Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with flexible displays face challenges in ensuring continuity of input methods when transitioning between folding and unfolding states, requiring separate input interfaces for each display state.
Innovation Solution
A method and device that output a first character input screen on a smaller display in a first operation state and transition to a second character input screen on a larger display in a second operation state, maintaining continuity of character input by including input buttons for the previously used input method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate input interfaces are provided for each display state, then the display can be operated in different folder states, but the input method continuity is disrupted during state transitions
Solution Approach 1:
The patent implements a universal input interface that functions across multiple display states (folded and unfolded). The character input screen maintains consistent functionality and layout regardless of the display's folder state, allowing the same input method to be used in both states without requiring separate interfaces for each state.
Solution Approach 2:
The patent preserves the selected character input method from the first display state before transitioning to the second display state. By maintaining the input method selection in memory and restoring it after state transition, the system performs the action of preserving input continuity in advance, ensuring no loss of input method information during the transition.
2Ease of operation
If the character input screen is reconfigured for each display state, then the interface can be optimized for each state, but the user must reselect input methods causing interruption
Solution Approach 1:
The patent ensures continuous character input capability across display state transitions by maintaining the selected input method active. The character input screen preserves its configuration and the user's input progress without interruption, allowing the useful action of character input to continue seamlessly from the first display state through the transition to the second display state without requiring reselection or reconfiguration.
3Ease of operation
If the input interface is simplified for smaller displays, then the smaller display is easier to operate, but the larger display does not utilize its full input capability
Solution Approach 1:
The patent implements a dynamic character input screen that adapts its layout and functionality based on the active display state. When the display is in the folded state with smaller visible area, the interface presents a simplified layout optimized for that form factor. When the display transitions to the unfolded state with larger area, the interface automatically adjusts to utilize the expanded space while maintaining consistency with the previously selected input method, thus achieving both ease of operation and full adaptability.

AI summary
A method for display in an electronic device is provided. The method includes outputting a first character input screen to a first display in a first operation state, and outputting a second character input screen, providing continuity of character input in the first display, to a second display in response to an occurrence of a transition event from the first operation state to a second operation state, wherein the first display, which is activated in the first operation state, has a relatively smaller screen size than the second display, which is activated in the second operation state, and wherein the second character input screen includes an input interface provided with having one or more input buttons for selecting a character input method used in the first operation state.
