Fingerprint Module Placement in Mobile Terminal Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The placement of a fingerprint identification module at the front surface of a mobile terminal results in an excessively large upper frame, necessitating a longer device size and affecting the appearance.
Innovation Solution
The fingerprint identification module is positioned adjacent to the non-display area of the terminal screen, with a cover plate glass defining a module accommodation hole to house the module, and a ring body fixed to both the cover plate glass and upper cover, ensuring central alignment and minimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fingerprint identification module is placed at the front surface of the terminal, then the module is easily accessible and visible, but the upper frame becomes excessively large requiring the device size to be lengthened
Solution Approach 1:
The patent transitions the fingerprint module from a horizontal arrangement (occupying upper frame space) to a vertical arrangement (positioned at the bottom edge of the display area). This dimensional change allows the module to maintain accessibility while eliminating the need to lengthen the device, as the module now utilizes vertical space rather than horizontal space.
2Ease of operation
If the fingerprint identification module is centrally arranged relative to the lower frame, then the module is easily accessible, but the upper frame size increases affecting appearance
Solution Approach 1:
The patent repositions the fingerprint module from a central horizontal arrangement that expands the upper frame to a vertical arrangement at the bottom edge of the display area. This dimensional repositioning maintains operational accessibility while preserving the upper frame's aesthetic proportions and overall device shape.
3Reliability
If the non-display area is arranged opposite to the upper frame, then the driving circuit is protected, but the upper frame becomes too large
Solution Approach 1:
The patent repositions the non-display area from a horizontal arrangement opposite the upper frame to a vertical arrangement at the bottom edge of the display area. This dimensional change allows the driving circuit to remain protected within the screen structure while eliminating the need to expand the upper frame length.

AI summary
A mobile terminal, comprising: a fingerprint recognition module (11) and a terminal screen (12); said terminal screen (12) comprising a display area (120) and a non-display area (121) positioned at one end of the display area (120), wherein said display area (120) has a display panel (1201); said fingerprint recognition module (11) is close to said non-display area (121), wherein a forward facing projection of said fingerprint recognition module (11) on a flat surface of said display panel (1201) at least partly overlaps with a forward facing projection of the non-display area (121) on the flat surface of said display panel (1201). The present invention is thus able to resolve the problem wherein a frame of a mobile terminal is excessively large when a fingerprint recognition module is positioned on the front of the mobile terminal, which would not only cause the overall dimensions to be increased, but also the outer appearance of the mobile terminal to be affected.
