Dynamic Fingerprint Region Highlighting for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smartphone fingerprint recognition systems consume excessive power and lack efficiency due to the constant enabling of fingerprint recognition functions across the entire screen, leading to uneven material and luminescent consumption, which affects accuracy and user experience.
Innovation Solution
A mobile terminal with a touch display screen and fingerprint recognition apparatus that dynamically determines a second region within a first region for fingerprint input, enabling the fingerprint recognition function only in this designated area and highlighting it to guide the user, thereby reducing power consumption and improving input accuracy and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fingerprint recognition function is enabled across the entire screen, then the user can input fingerprints from any location, but power consumption increases and material/luminescent usage becomes uneven
Solution Approach 1:
The patent applies local quality by enabling the fingerprint recognition function only in a specific second region within the first region, rather than across the entire screen. This localized approach reduces power consumption and prevents uneven material/luminescent usage while still providing adequate fingerprint input capability. The second region is dynamically determined based on operation conditions, making the system both energy-efficient and adaptable.
2Ease of operation
If the fingerprint recognition function is enabled across the entire screen, then fingerprint input is convenient, but accuracy and input speed decrease due to lack of user guidance
Solution Approach 1:
The patent uses visual highlighting (color/brightness changes) to mark the second region where fingerprint input is expected. This visual guidance helps users quickly locate the correct input area, improving input accuracy and speed while maintaining ease of operation. The highlighted region acts as a clear visual cue without requiring users to search the entire screen.
Solution Approach 2:
By concentrating the fingerprint recognition function in a specific highlighted second region, the system provides clear user guidance while maintaining operational convenience. Users are directed to the precise input location through visual feedback, improving accuracy without significantly reducing ease of use.
3Area of stationary object
If the fingerprint recognition function is enabled across the entire screen, then comprehensive coverage is achieved, but resource consumption becomes uneven and efficiency decreases
Solution Approach 1:
The patent achieves optimal balance by enabling fingerprint recognition in a specifically determined second region rather than the entire first region. This localized approach concentrates resources where they are most needed, improving input efficiency while maintaining sufficient coverage for user needs. The second region is dynamically selected based on operation conditions to optimize both coverage and efficiency.
Solution Approach 2:
The patent segments the fingerprint recognition area into a first region (overall fingerprint recognition region) and a second region (specific active fingerprint input area). This segmentation allows the system to maintain comprehensive coverage capability while concentrating active recognition resources in a smaller, more efficient area, thereby improving overall productivity.

AI summary
A mobile terminal, a method and a device for displaying a fingerprint recognition region are provided. The method is applied to a mobile terminal including a processor, a touch display screen and a fingerprint recognition apparatus, in which a fingerprint recognition region of the fingerprint recognition apparatus includes a first region of the touch display screen. The method may include: determining a second region when an operation for the mobile terminal satisfies a condition for inputting a fingerprint, in which the second region is in a range of the first region; and enabling a fingerprint recognition function of the fingerprint recognition apparatus in the second region, and highlighting the second region.
