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

The embodiments of the invention disclose electromagnetic interference control methods and a related device. A method comprises the steps of detecting whether electromagnetic interference occurs between a radio frequency system and a display screen of electronic equipment or not when it is detected that the electronic equipment is in a preset scene, wherein the preset scene comprises a bright screen scene; and carrying out frequency hopping switching operation for a display screen mobile industry processor interface (MIPI) when it is detected that the electromagnetic interference occurs in theelectronic equipment. According to the method and the device, communication stability in the bright screen scene can be improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, 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: 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) ...
