Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fingerprint sensors in electronic devices are limited to user authentication and cannot flexibly control device functions, restricting the use of fingerprints for other purposes beyond pre-assigned functions.
Innovation Solution
An electronic device that senses fingerprints through its display, allowing fingerprints to be mapped to specific functions of applications, enabling flexible control of screen operations by mapping a single fingerprint to multiple functions across different applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a small-sized fingerprint sensor is provided in an outer portion of the electronic device, then fingerprint recognition function is achieved, but the device cannot flexibly control various functions and is limited to pre-assigned functions only
Solution Approach 1:
The display device is designed to serve dual purposes: it functions as both a visual display and a fingerprint sensor. The same display hardware can recognize fingerprints and control multiple functions across different applications, eliminating the need for separate dedicated sensors for each function.
Solution Approach 2:
The patent combines the fingerprint sensing capability with the display device by integrating a fingerprint sensor within the display structure. This merging allows the display to perform both its traditional function and fingerprint recognition, reducing the need for additional separate components.
2Adaptability or versatility
If each function is previously assigned a fingerprint, then authentication is achieved, but other purposes cannot be used for the same function
Solution Approach 1:
The system dynamically assigns functions to fingerprints based on the current application context rather than having static, pre-assigned mappings. When a user touches an object in a specific application, the system maps the fingerprint to that application's function, allowing flexible reassignment without reconfiguration.
Solution Approach 2:
The system performs preliminary function assignment by detecting which application is currently active and pre-mapping the fingerprint to that application's relevant function before the user actually uses it. This eliminates the need for users to manually reassign functions when switching applications.
3Adaptability or versatility
If a fingerprint sensor is used only for user authentication, then security function is achieved, but the sensor cannot control other device functions
Solution Approach 1:
The display device is designed to serve dual purposes: it functions as both a visual display and a fingerprint sensor. The same display hardware can recognize fingerprints and control multiple functions across different applications, eliminating the need for separate dedicated sensors for each function.

AI summary
Disclosed is an electronic device for sensing a fingerprint, including a display including at least one sensor for sensing the fingerprint, a memory, and at least one processor electrically connected with the display and the memory, wherein the processor may execute an application and display the application on the display, sense a first fingerprint inputted to at least one first region of the application displayed on the display, map the sensed first fingerprint to a function corresponding to the first region, determine whether the first fingerprint is sensed on the application, and if the first fingerprint is sensed on the display, apply the mapped function to the display.
