ELECTRONIC DEVICE AND METHOD FOR ACQUIRING FINGERPRINT INFORMATION THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17837728 titled 'ELECTRONIC DEVICE AND METHOD FOR ACQUIRING FINGERPRINT INFORMATION THEREOF

Simplified Explanation

An electronic device is described in this patent application. The device includes a light source, a fingerprint sensor, a memory, and a processor.

  • The light source is used to create an irradiation area on a display surface by illuminating the display. This area includes a fingerprint recognition area.
  • The fingerprint sensor detects the reflected light from the display surface.
  • The memory stores an image of the reflected light when the light source is turned on.
  • The processor is connected to the light source, fingerprint sensor, and memory.
  • The processor can control the light source to irradiate light in a designated direction.
  • The processor can obtain an image of the reflected light and analyze it to determine if the object detected by the fingerprint sensor is flat or three-dimensional.

Potential applications of this technology:

  • Enhanced fingerprint recognition on electronic devices.
  • Improved security features on devices such as smartphones, tablets, and laptops.
  • More accurate and reliable fingerprint authentication for access control systems.

Problems solved by this technology:

  • The technology helps to distinguish between flat and three-dimensional objects when using fingerprint recognition.
  • It improves the accuracy and reliability of fingerprint authentication by analyzing the reflected light.

Benefits of this technology:

  • Enhanced security and protection against unauthorized access.
  • Improved user experience with faster and more accurate fingerprint recognition.
  • Potential for integration into various electronic devices for enhanced security features.


Original Abstract Submitted

An electronic device is provided. The electronic device includes a light source, a fingerprint sensor, a memory configured to record an image of a reflected light detected when the light source is turned on, and a processor configured to operatively coupled to the light source, the fingerprint sensor, and the memory, wherein the light source may form an irradiation area on a display surface by light irradiation to a display, the irradiation area may include a fingerprint recognition area formed on the display, at least one surface may match the fingerprint recognition area or at least one vertex coincides, and the matched area may form a first area. The memory may store instructions allowing the processor to irradiate light in a designated direction using the light source, obtain a first image and analyze the first image to distinguish whether the object detected by the fingerprint sensor is flat or three-dimensional.
