Engineering Contradiction Analysis
1Area of stationary object
If a foldable screen structure is adopted to provide large-screen experience, then the display area is improved, but the operation complexity increases due to specific folding sequence requirements
Solution Approach 1:
The patent implements real-time detection of the folding sequence through sensors that monitor the state of each screen segment. When an incorrect folding sequence is detected, the system provides feedback to the user through prompt information, guiding them to correct the folding operation. This feedback mechanism reduces operation complexity by automatically detecting and correcting folding sequence errors.
Solution Approach 2:
The system performs self-detection of folding sequence correctness through integrated sensors and control circuits. The foldable screen structure itself provides the detection capability through its own components, eliminating the need for external monitoring devices. This self-service approach simplifies the overall system while maintaining high display area benefits.
2Reliability
If real-time detection of folding sequence anomalies is implemented, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the detection function with the existing foldable screen structure by integrating sensors and control circuits into the screen segments themselves. Rather than adding a separate detection system, the detection capability is combined with the structural components, reducing overall device complexity while maintaining high reliability through real-time monitoring.
Solution Approach 2:
The sensors and control circuits serve multiple functions: they detect folding sequence anomalies, determine screen segment states, and provide user guidance. This multi-functionality reduces the need for separate dedicated components, thereby reducing device complexity while improving reliability through comprehensive monitoring.

AI summary
This application provides a foldable screen control method and an electronic device, and relates to the field of electronic technologies. The method includes: receiving a folding operation performed on a foldable screen, and sending first prompt information in response to a folding sequence anomaly of the foldable screen in response to the folding operation. The foldable screen includes a first screen, a second screen, a third screen, a first folding axis, and a second folding axis. The first folding axis is located between the first screen and the second screen and is configured to allow the first screen to be folded or unfolded relative to the second screen. The second folding axis is located between the second screen and the third screen and is configured to allow the third screen to be folded or unfolded relative to the second screen. In a correct folding sequence, the third screen is first folded and the first screen is then folded. Technical solutions provided in this application can help a user perform folding in a correct folding sequence, improving user's operation experience.
