ELECTRONIC DEVICE COMPRISING DISPLAY-EMBEDDED FINGERPRINT SENSOR AND METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18489017 titled 'ELECTRONIC DEVICE COMPRISING DISPLAY-EMBEDDED FINGERPRINT SENSOR AND METHOD

Simplified Explanation

An electronic device is described in this patent application. The device includes a display panel with light-emitting elements and a fingerprint sensing region. Below the fingerprint sensing region, there is a fingerprint sensor. The device also has at least one processor that is connected to either the display panel or the fingerprint sensor. The processor is configured to identify when an event occurs that triggers the operation of receiving a fingerprint through the fingerprint sensor. It then obtains a first image of the fingerprint by controlling the display panel to emit light from the light-emitting elements in a specific region within the fingerprint sensing region. It also obtains a second image of the fingerprint by controlling the display panel to emit light from the light-emitting elements in a different region that does not overlap with the first region. The processor uses these images to determine whether the fingerprint is a three-dimensional object.

  • The electronic device includes a display panel with light-emitting elements and a fingerprint sensing region.
  • A fingerprint sensor is positioned below the fingerprint sensing region.
  • At least one processor is connected to the display panel or the fingerprint sensor.
  • The processor can identify when an event occurs that triggers the operation of receiving a fingerprint.
  • The processor controls the display panel to obtain a first image of the fingerprint by emitting light from specific light-emitting elements in a region within the fingerprint sensing region.
  • The processor controls the display panel to obtain a second image of the fingerprint by emitting light from specific light-emitting elements in a different region that does not overlap with the first region.
  • The processor uses the first and second images to determine whether the fingerprint is a three-dimensional object.

Potential applications of this technology:

  • Biometric authentication in electronic devices such as smartphones, tablets, and laptops.
  • Enhanced security measures for access control systems in buildings and facilities.
  • Identity verification in banking and financial transactions.
  • Forensic analysis and crime investigation.

Problems solved by this technology:

  • Improved accuracy in fingerprint recognition by considering the three-dimensional nature of fingerprints.
  • Enhanced security by detecting fake or spoofed fingerprints that lack depth information.
  • Reduction in false positives or false negatives in fingerprint authentication systems.

Benefits of this technology:

  • Higher level of security and protection against unauthorized access.
  • Improved user experience with faster and more reliable fingerprint recognition.
  • Potential cost savings by reducing the need for additional authentication methods or devices.
  • Enhanced forensic capabilities for law enforcement agencies.


Original Abstract Submitted

An electronic device includes: a display panel including a plurality of light-emitting elements and a fingerprint sensing region; a fingerprint sensor disposed below the fingerprint sensing region; and at least one processor electrically connected to the display panel or the fingerprint sensor, and configured to identify an occurrence of an event that causes an operation of receiving a fingerprint through the fingerprint sensor to be executed, obtain a first image of the fingerprint by controlling the display panel such that light-emitting elements disposed in a first light-emitting region within the fingerprint sensing region output light, obtain a second image of the fingerprint by controlling the display panel such that light-emitting elements disposed in a second light-emitting region that does not overlap the first light-emitting region output light, and determine whether the fingerprint is a three-dimensional object, by using the first image and the second image.
