Foldable Phone Call Prompting Across Dual Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a flexible screen electronic device receives a call request, if the screen folded away from the user's line of sight, the user cannot perceive incoming call information, leading to missed calls.
Innovation Solution
The device determines a target screen based on the call type and hardware components, displaying incoming call information on that screen and prompt information on the other screen to guide the user to use appropriate hardware for the call.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If incoming call information is displayed on a single screen (first screen), then the display is simple and clear, but the user cannot perceive the call request when the screen is folded away from line of sight
Solution Approach 1:
The display is segmented into two separate screens (first screen and second screen). When the flexible screen is folded, the first screen displays incoming call information while the second screen displays prompt information, ensuring the user can perceive the call request regardless of which screen is visible.
Solution Approach 2:
The solution transitions from a single-dimension display (one screen) to a two-dimension display (two screens). By utilizing both screens simultaneously to display different types of information, the system ensures call perception reliability without significantly increasing operational complexity.
2Reliability
If incoming call information is displayed on both screens, then the user can always see the call request, but the information display becomes redundant and confusing
Solution Approach 1:
Different regions (screens) have different display functions optimized for their purpose. The first screen is dedicated to displaying incoming call information (caller ID, call options), while the second screen displays prompt information guiding the user to flip the device. This local differentiation eliminates redundancy while maintaining clarity.
Solution Approach 2:
The information display is segmented into two distinct types: incoming call information on the first screen and prompt information on the second screen. This segmentation ensures each screen presents only the necessary information for its specific function, avoiding confusion.
3Ease of operation
If the device always displays incoming call information on the first screen, then the display logic is simple, but the user may miss calls when the first screen is not visible
Solution Approach 1:
The display system dynamically adapts its behavior based on the folding state of the flexible screen. When folded, the system automatically distributes information across both screens; when unfolded, it can display on the appropriate screen. This dynamic adaptation maintains simple display logic while significantly improving call notification reliability.
4Ease of operation
If prompt information is displayed on the non-target screen, then the user is guided to the correct screen, but the non-target screen consumes power displaying information
Solution Approach 1:
The prompt information function is extracted from the main incoming call information display and placed on the second screen. This allows the first screen to focus on displaying critical call information while the second screen provides guidance, optimizing the overall system efficiency and user guidance without excessive power consumption.

AI summary
This application provides an incoming call prompting method and an electronic device, and relates to the field of terminal technologies, to guide, on a flexible screen, a user to use a proper screen to process a call request from a contact, thereby reducing missed calls. The method includes: An electronic device receives a call request from a contact; when a flexible screen of the electronic device is in a folded state, the electronic device determines, in response to the call request, a target screen corresponding to the call request, where the target screen is a first screen or a second screen of the flexible screen; and the electronic device displays an answer button on the target screen, and the electronic device displays prompt information of the call request on a non-target screen, where the prompt information is used to prompt a user to answer the current call request by using the answer button displayed on the target screen.
