Solution Overview
Problem
There is insufficient space on flexible display screens in mobile terminals to accommodate millimeter-wave antenna modules effectively, which hinders their functionality and performance.
Innovation Solution
The integration of a millimeter-wave antenna module at the edge of a flexible display screen that can be expanded or retracted, with a control module to manage its working state based on the screen's configuration, using a Hall sensor and magnet for detection, and an antenna switch for manual control, ensuring optimal performance regardless of the screen's state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the flexible display screen is expanded to provide more space, then the area available for antenna modules increases, but the device size and portability are compromised
Solution Approach 1:
The flexible display screen is designed to be dynamically changeable between expanded and retracted states. When expanded, it provides sufficient area for millimeter-wave antenna modules; when retracted, it maintains a compact device form factor for portability. This dynamic configuration allows the system to adapt between the two conflicting requirements of space availability and compact size.
2Reliability
If the millimeter-wave antenna module is always active, then communication performance is maintained, but power consumption increases and space is occupied when not needed
Solution Approach 1:
The millimeter-wave antenna module is controlled to operate periodically rather than continuously. The control module activates the antenna module only when the flexible display screen is in the expanded configuration and millimeter-wave communication is needed. When the screen is retracted or communication is not required, the antenna module is deactivated, thereby reducing power consumption while maintaining communication performance when needed.
3Area of stationary object
If the antenna module is integrated into the flexible display screen, then space utilization is optimized, but the complexity of the display screen structure increases
Solution Approach 1:
The millimeter-wave antenna module is merged with the flexible display screen structure, integrating two functional components into a single unified structure. The antenna module is positioned at the edge of the flexible display screen, allowing it to share the same structural framework and control systems, thereby optimizing space utilization while managing structural complexity through integration rather than separate components.

Function Achieved in This Case
This solution allows for efficient use of space on mobile terminals while ensuring the millimeter-wave antenna module operates optimally, enhancing antenna performance and user experience by automatically adjusting its state with the flexible display screen's configuration.
Implementation Method 1
a configuration detection component; the control module is connected with the configuration detection component; and the control module is configured to determine whether the flexible display screen is in the retracted configuration or in the expanded configuration according to a signal output by the configuration detection component

AI summary
A mobile terminal includes a body, and a flexible display screen disposed at the body. The flexible display screen is switchable between an expanded configuration and a retracted configuration. In the expanded configuration, the flexible display screen is expanded to a first area, and in the retracted configuration, the flexible display screen is retracted to a second area. The first area is larger than the second area. A millimeter-wave antenna module is disposed at an edge of the flexible display screen. The method includes: controlling the millimeter-wave antenna module to be in a non-working state when the flexible display screen is in the retracted configuration; and controlling the millimeter-wave antenna module to be in a working state when the flexible display screen is in the expanded configuration.
