Abstract

A method for aligning a fingerprint sensing area of a display element with a fingerprint sensing module is suitable for an electronic device that includes a display element having a fingerprint sensing area, a controller, and a fingerprint sensing module. The alignment method includes: the controller activates the display element to emit an irradiating light beam from the fingerprint sensing areato an object which reflects the irradiating light beam to the fingerprint sensing module, wherein the light source pattern of the irradiating light beam exhibits a feature that the light signal intensity in a first area closer to the center is less than that in a second area far from the center; the fingerprint sensing module senses the reflected light formed by the irradiating light beam reflected by the object to obtain raw data, wherein the raw data is the sum of the reflected light signal intensity sensed by the fingerprint sensing module; the controller adjusts the position of the light source pattern at the display element; the fingerprint sensing module senses the adjusted reflected light to obtain the adjusted data, wherein the adjusted data is the sum of the reflected light signalintensity sensed by the fingerprint sensing module after the position of the light source pattern is adjusted; and the position of the light source pattern is adjusted based on the raw data and the adjusted data.

Description

technical field [0001] The present invention relates to a method for aligning a display element and a sensing module, and in particular to a method for aligning a fingerprint sensing area of ​​a display element and a fingerprint sensing module in an electronic device. Background technique [0002] With the continuous evolution and improvement of electronic technology and manufacturing technology, information electronic products are constantly being introduced. Computers, mobile phones, cameras and other electronic products are already necessary tools for modern people. In addition, today's smart mobile devices also need to integrate fingerprint recognition devices to enhance the security of the smart mobile devices and support more smart functions. [0003] Currently, users can press their fingers on the display or cover of the mobile phone for fingerprint recognition. However, during the sensing process, the brightness of the reflected light signal sensed by the sensing p...
