Abstract

The present application relates to an electromagnetic interference control method, including: acquiring the current communication channel of the electronic device when the electronic device is in a bright screen state; and detecting that the driving frequency of the display screen interferes with the current communication channel of the electronic device , an adjustment operation is performed on the driving frequency of the display screen, and the adjustment operation is frequency hopping or spreading. The invention also discloses an electromagnetic interference control device, electronic equipment and a computer-readable storage medium. The invention avoids the driving frequency of the display screen from the current communication channel of the electronic equipment, and avoids the influence of the driving frequency of the display screen on the communication quality of the electronic equipment.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to an electromagnetic interference control method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the development of mobile communication technology, users have higher and higher demands on electronic devices such as mobile phones. When electronic devices transmit data, they generally use cellular mobile network data or WiFi, etc. However, as the screen ratio of electronic devices becomes larger and larger, the headroom of the antenna becomes smaller and smaller, and the driving circuit of the display screen may invade The clearance area of ​​the antenna will interfere with the communication quality. Contents of the invention [0003] Embodiments of the present application provide an electromagnetic interference control method and device, electronic equipment, and a computer-readable storage mediu...
