Problems solved by technology

[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 radio frequency interference problems: the driver integrated chip of the display screen has extended to the antenna clearance area, and the frequency division and multiplication point of the MIPI frequency of the mobile industry processor interface of the display screen interferes with the radio frequency antenna, resulting in the receiving sensitivity of the antenna (Total Isotropic Sensitivity, TIS) is relatively low

Abstract

Embodiments of the application disclose a method for controlling electromagnetic interference and related devices. The method comprises the following steps: starting a wireless high-fidelity Wi-Fi module when detecting a screen projection request for target screen projection equipment; searching for and accessing a target wireless network, which is connected with the target screen projection equipment; detecting whether the Wi-Fi module and the display mobile industry processor interface MIPI have electromagnetic interference; when detecting electromagnetic interference, outputting first prompt information, extinguishing the display screen, and performing the screen projection operation, wherein the first prompt information is used to indicate that the electronic equipment is performing the screen-out projection operation. The application is useful for avoiding the electromagnetic interference between the Wi-Fi module and the display mobile industry interface MIPI, thereby improving the stability of communication in a screen projection scenario.
