Abstract

The embodiment of the present application discloses an electromagnetic interference control method and a related device. The method includes: obtaining the frequency data packet of the Bluetooth module; Perform data transmission between the first bluetooth channel and the bluetooth device; switch the first bluetooth channel to the second bluetooth channel to reduce or avoid the electromagnetic interference, and send a first message to the bluetooth device, the first message The second Bluetooth channel is included. The embodiments of the present application are beneficial to reduce or avoid electromagnetic interference between the Bluetooth module and the display screen.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and in particular to an electromagnetic interference control method and a related device. Background technique [0002] With the development of mobile communication technology, users have an increasing demand for communication with mobile phones and other electronic devices. At present, when electronic devices on the market transmit data, they generally transmit data through cellular mobile network communication or Wi-Fi communication. , full-screen mobile phones are facing the problem of radio frequency interference. [0003] Among them, when the display screen of the electronic device and the Bluetooth module work at the same time, the operating frequency of certain channel frequency bands of the Bluetooth module may generate electromagnetic interference on the display screen, which will lead to a decrease in the display performance of the display screen or a decrease in ...
