Electromagnetic interference control method and related products

Abstract

The embodiment of the application discloses an electromagnetic interference control method and related products. If a display screen is in a bright-screen state when electronic equipment is in a calling scene, target working frequency of a modem is acquired, first MIPI working frequency of a display screen MIPI (mobile industry processor interface) is acquired, whether interference with the targetworking frequency exists is determined according to the first MIPI working frequency, and if yes, second MIPI working frequency corresponding to the calling scene is determined, and the display screen MIPI working frequency is adjusted as the second MIPI working frequency. Therefore, the display screen MIPI working frequency can be dynamically adjusted in a case, where a hardware design of the electronic equipment is unchanged, when the electronic equipment is in different user scenes, the display screen MIPI is enabled to work at frequency lesser interfering with the modem, thus electromagnetic interference thereof with modem communication is eliminated or reduced, and best communication performance and calling quality are obtained.

Description

technical field [0001] This application relates to the field of electronic technology, in particular to an electromagnetic interference control method and related products. 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. When the mobile industry processor interface (MIPI) of the display screen used to transmit data works at a fixed frequency, if its frequency division frequency or multiplication frequency falls within a specific working frequency In terms of frequency, there may be various modules that interfere with the MIPI of the display screen, such as communication modules and audio modules,...

[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. When the mobile industry processor interface (MIPI) of the display screen used to transmit data works at a fixed frequency, if its frequency division frequency or multiplication frequency falls within a specific working frequency In terms of frequency, there may be various modules that interfere with the MIPI of the display screen, such as communication modules and audio modules, which will affect the functional stability of each module in the electronic device

[0003] At present, the interference to each module can be improved through hardware upgrades, but it will increase the cost and the improvement effect is limited. Therefore, how to reduce the interference of the MIPI operating frequency of the display screen to each module of the electronic device needs to be solved urgently
