Abstract

The invention relates to an electromagnetic interference control method, which comprises the steps of obtaining a current communication channel of electronic equipment when the electronic equipment is in a screen-on state; and when it is detected that the driving frequency of the display screen interferes with the current communication channel of the electronic device, adjusting operation is executed for the driving frequency of the display screen, and the adjusting operation is frequency hopping or spectrum spreading. The invention also discloses an electromagnetic interference control device, electronic equipment and a computer readable storage medium. The driving frequency of the display screen is enabled to avoid the current communication channel of the electronic equipment, and the influence of the driving frequency of the display screen on the communication quality of the electronic equipment is avoided.

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...
