Problems solved by technology

[0002] With the development of mobile communication technology, more and more functions are integrated in mobile phones and other electronic devices. At present, many mobile phones are integrated with fingerprint modules under the screen to realize the fingerprint unlocking function under the screen. The MIPI frequency of the mobile industry processor interface of the screen may be different from that of the screen. The working frequency of the lower fingerprint module produces electromagnetic interference, resulting in fingerprint recognition errors and unlocking failures

Abstract

An embodiment of the present application discloses an electromagnetic interference control method and a related device. The electronic device comprises a display screen and an under-screen fingerprintmodule arranged in a preset area of the display screen. The method comprises: detecting whether an electromagnetic interference occurs between the under-screen fingerprint module and the display screen when the under-screen fingerprint module is detected to be in a startup state, and the preset area of the display screen is in a lighted state; a frequency hopping switching operation is performedfor a display screen mobile industry processor interface MIPI when an electromagnetic interference between an under-screen fingerprint module and the display screen is detected. The present application facilitates accuracy and stability of off-screen fingerprint unlocking by an electronic device.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to an electromagnetic interference control method and a related device. Background technique [0002] With the development of mobile communication technology, more and more functions are integrated in mobile phones and other electronic devices. At present, many mobile phones are integrated with fingerprint modules under the screen to realize the fingerprint unlocking function under the screen. The MIPI frequency of the mobile industry processor interface of the display screen may be different from the screen The working frequency of the lower fingerprint module produces electromagnetic interference, which causes fingerprint recognition errors and unlocking failures. Contents of the invention [0003] Embodiments of the present application provide an electromagnetic interference control method and a related device, in order to improve the accuracy and stabili...
