US 11,690,206 B2 · Method for electromagnetic interference control, electronic device, and storage medium

Abstract

A method for electromagnetic interference control, an electronic device, and a storage medium are provided. The method is for an electronic device. The electronic device includes a display screen and an under-screen fingerprint assembly arranged under a preset region of the display screen. The method includes the following. Detect electromagnetic interference between the under-screen fingerprint assembly and the display screen in response to detecting that the under-screen fingerprint assembly is activated, where the preset region of the display screen is in a lighted state. Frequency-hopping is performed for a mobile industry processor interface (MIPI) of the display screen in response to the detected electromagnetic interference.

Dependent claims

A method for electromagnetic interference control, for an electronic device comprising a display screen and an under-screen fingerprint assembly arranged under a preset region of the display screen, the method comprising:

detecting electromagnetic interference between the under-screen fingerprint assembly and the display screen in response to detecting that the under-screen fingerprint assembly is activated, wherein the preset region of the display screen is in a lighted state;
and
performing frequency-hopping for a mobile industry processor interface (MIPI) of the display screen in response to the detected electromagnetic interference.

An electronic device comprising:

a display screen;
an under-screen fingerprint assembly arranged under a preset region of the display screen;
at least one processor;
and
a memory, coupled to the at least one processor and storing at least one computer executable instruction thereon which, when executed by the at least one processor, causes the at least one processor to:
detect electromagnetic interference between the under-screen fingerprint assembly and the display screen in response to detecting that the under-screen fingerprint assembly is activated, wherein the preset region of the display screen is in a lighted state, and perform frequency-hopping for a mobile industry processor interface (MIPI) of the display screen in response to the detected electromagnetic interference.
