Problems solved by technology

[0002] With the continuous development of fingerprint collection technology, electronic devices such as mobile phones can now support the fingerprint recognition function under the screen. After the user activates the mobile phone, he can trigger the mobile phone to collect fingerprint patterns through the fingerprint module under the screen by pressing the power button. Due to the influence of optical noise on the captured image of the under-screen fingerprint module, the recognition success rate is still difficult to meet the same requirements of the traditional mobile phone fingerprint module.

Abstract

The embodiment of the application discloses an under-screen fingerprint module, an electronic device and a fingerprint image processing method. The electronic device comprises a screen and an under-screen fingerprint module arranged in a preset area relative to the screen. The screen is provided with a first polarizer, the fingerprint module under the screen is provided with a second polarizer, and the polarizing directions of the first polarizer and the second polarizer are identical; the first polarizer and the second polarizer are used for filtering the first optical noise, the first optical noise is reflected light, the reflected light is light reflected by the first light through the screen, and the first light is light irradiated in the Z-axis of the screen; the second polarizer is used for filtering the second optical noise, the second optical noise is a direct light ray, and the direct light ray is a second light ray emitted from the emitted light ray, which is reversely irradiated along the Z-axis of the screen. Embodiments of the present application are advantageous in reducing optical noise of fingerprints and improving accuracy and efficiency of fingerprint acquisitionby electronic devices.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to an under-screen fingerprint module, electronic equipment and a fingerprint image processing method. Background technique [0002] With the continuous development of fingerprint collection technology, electronic devices such as mobile phones can now support the fingerprint recognition function under the screen. After the user activates the mobile phone, he can trigger the mobile phone to collect fingerprint graphics through the fingerprint module under the screen by pressing the power button. At present, due to the influence of optical noise on the captured image of the fingerprint module under the screen, the recognition success rate is still difficult to meet the same requirements of the traditional mobile phone fingerprint module. Contents of the invention [0003] The embodiment of the present application provides an under-screen fingerprint module, an...
