Flexible Display Movable Portion Covers Side-Face Fingerprint Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fingerprint identification technologies in electronic devices often compromise the screen-to-body ratio and user experience due to the fixed placement of fingerprint modules, which limits flexibility and convenience in fingerprint recognition methods.
Innovation Solution
An electronic device design incorporating a flexible display screen with a movable portion that covers or exposes a fingerprint identification module, allowing for fingerprint recognition through the screen in both folded and unfolded states, thereby enhancing user experience and screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the fingerprint identification module is fixed on the front face of the housing, then the structure is simple and easy to manufacture, but the screen-to-body ratio is reduced and user experience is compromised
Solution Approach 1:
The fingerprint identification module is relocated from the front face to the side face of the housing, utilizing a different spatial dimension. This allows the module to be positioned in a mounting groove on the side face, enabling the display screen to extend fully across the front face and achieve a higher screen-to-body ratio while maintaining easy access for fingerprint recognition.
Solution Approach 2:
The fingerprint identification module is nested within a mounting groove on the side face of the housing. This nested structure allows the module to be integrated into the housing profile without protruding significantly, maintaining a sleek appearance while preserving ease of manufacture and assembly.
2Area of moving object
If the fingerprint identification module is placed on the side face in a mounting groove, then the screen-to-body ratio is improved, but the structure becomes more complex
Solution Approach 1:
The housing is segmented into distinct functional zones: the front face for display, the side face with mounting groove for fingerprint recognition, and the back face for battery and other components. This segmentation allows each component to be optimized independently and assembled systematically, reducing overall structural complexity despite the relocated module.
Solution Approach 2:
The side face of the housing serves multiple functions: it provides structural support, contains the mounting groove for the fingerprint module, and maintains the overall housing integrity. This multi-functionality reduces the need for additional specialized components, thereby controlling structural complexity.
3Ease of manufacture
If the display screen is fixed to the top face only, then the installation is simple, but the flexibility and user convenience are reduced
Solution Approach 1:
The display screen is designed with flexible support structures that allow it to be mounted not only on the top face but also extend along the side faces of the housing. This dynamic mounting approach enables the screen to adapt to different viewing angles and device orientations, enhancing flexibility and user convenience while maintaining relatively simple installation procedures.

AI summary
An electronic device is provided and includes a flexible display screen, a fingerprint identification module and a housing. The housing has a top face and a side face connected with each other, the side face is provided with a mounting groove, the fingerprint identification module is accommodated in the mounting groove. The flexible display screen includes a fixed portion and a movable portion connected with each other, the fixed portion being fitted to the top face, and the movable portion extending beyond the top face. When the movable portion is bent relative to the fixed portion, the movable portion covers the side face and the fingerprint identification module performs fingerprint identification through the flexible display screen. When the movable portion is spread out relative to the fixed portion, the fingerprint identification module is exposed out of the flexible display screen.
