Electromagnetic Interference Control Method and Related Products

Abstract

The embodiment of the present application discloses an electromagnetic interference control method and related products. When the electronic device is in a call scene, if the display screen is in a bright state, the target operating frequency of the modem is obtained, and the MIPI number of the display screen is obtained. A MIPI operating frequency, determine whether the target operating frequency is disturbed according to the first MIPI operating frequency, if so, determine the second MIPI operating frequency corresponding to the call scene, adjust the MIPI operating frequency of the display screen to the second MIPI operating frequency, In this way, without changing the hardware design of the electronic device, the MIPI operating frequency of the display screen can be dynamically adjusted when the electronic device is in different user scenarios, so that the MIPI of the display screen can work at a working frequency that interferes less with the modem, thereby eliminating or reducing Its electromagnetic interference to modem communication can obtain the best communication performance and call quality.

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
