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. For example, when electronic devices are performing live video broadcasting, the frame rate and definition of the display screen are required to be high. The mobile industry processor interface (mobile industry processor interface, When MIPI) works at a fixed frequency, if its frequency division frequency or multiplication frequency falls on a specific operating frequency, there may be various modules that interfere with the MIPI of the display screen, such as communication modules and audio modules, thus affecting electronic equipment. Functional stability of individual modules
[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

Abstract

Embodiments of the application disclose an electromagnetic interference control method and a relevant product. The electromagnetic interference control method comprises the following steps: if a display screen is in an on state when electronic equipment is in a video mode, acquiring target working frequency of modem; acquiring the first MIPI working frequency of a display screen MIPI; determiningwhether the target working frequency is interfered or not according to the first MIPI working frequency; if so, determining the target video frame rate of a video; determining a second MIPI working frequency corresponding to the target video frequency; and adjusting the MIPI working frequency of the display screen to the second MIPI working frequency. Thus, the MIPI working frequency of the display screen can be dynamically adjusted when the electronic equipment is in the video mode under the condition of not changing the hardware design of the electronic equipment, thereby eliminating or lowering the electromagnetic interference on modem communication, and achieving best communication performance.
