Side Display Fingerprint Layout for Full-Screen Terminal Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of integrating fingerprint identification elements into full-screen displays, especially when the display extends to the side of the middle frame, is that the available space for these elements becomes increasingly limited, necessitating a reconfiguration of their layout to maintain functionality.
Innovation Solution
A display screen module with a fingerprint identification unit that is partially covered by a side display area, allowing the unit to obtain fingerprint images without occupying under-screen space in the front display area, and utilizing a flexible substrate with thin-film sensors for enhanced identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display screen extends to the side of the middle frame to achieve full-screen display, then the screen ratio approaches 100% and sensory experience is improved, but the space reserved for fingerprint identification elements becomes increasingly limited
Solution Approach 1:
The fingerprint identification unit is moved from the traditional front display area to the side display area, utilizing the vertical space along the middle frame. This dimensional relocation allows the fingerprint sensor to be positioned in an previously underutilized region, resolving the space conflict between full-screen display and fingerprint identification elements.
Solution Approach 2:
The display screen is segmented into front display area and side display area, with each area serving different functions. The front display area maintains full-screen visual output while the side display area accommodates the fingerprint identification unit, allowing both functions to coexist without interfering with each other.
2Ease of operation
If the fingerprint identification unit is placed in the front display area, then it is easily accessible, but it occupies under-screen space and reduces the effective display area
Solution Approach 1:
The fingerprint identification unit is relocated to the side display area along the middle frame, utilizing the vertical dimension rather than the horizontal under-screen space. This positioning maintains ease of operation as users can still easily reach the side area, while preserving the full under-screen display area for visual content.
3Area of moving object
If the side display area is used for fingerprint identification, then the fingerprint sensing area is increased, but the display screen layout needs to be reconfigured
Solution Approach 1:
The display screen is divided into distinct functional zones: front display area for visual output and side display area for fingerprint identification. This segmentation allows the side display area to be optimized for sensor placement while the front area maintains its display functionality, reducing layout complexity through clear functional separation.
Solution Approach 2:
The side display area serves dual purposes: it can display information when needed and simultaneously house the fingerprint identification unit. This multi-functionality maximizes the utility of the side area while maintaining a relatively simple overall layout structure.

AI summary
A display screen module includes a display screen and a fingerprint identification unit. The display screen includes a front display area and a side display area. The side display area at least partially covers the fingerprint identification unit, and the fingerprint identification unit is configured to obtain a fingerprint image. As the fingerprint identification unit is at least partially covered by the side display area, it can reduce or even needs not to occupy under-screen space of the front display area, and arrangement of the components can be optimized. When the user directly holds the side display area to which the fingerprint identification unit corresponds, fingerprint unlocking can be executed directly, which brings new fingerprint unlocking experience to the user, and also makes the unlocking process easier.
