Electromagnetic Interference Control Method and Related Products

Abstract

Embodiments of the application disclose a method for controlling electromagnetic interference, and related products. The method comprises the following steps: when an electronic device turns on the camera, acquiring a first MIPI (mobile industry processor interface) working frequency of an MIPI of the camera, acquiring a second MIPI working frequency of an MIPI of a display screen, determining whether the first MIPI working frequency is interfered or not according to the second MIPI working frequency, acquiring a frame rate and a resolution of the display screen if yes, determining a third MIPI working frequency generating less interference to the first MIPI working frequency than the second MIPI operating frequency according to the frame rate and the resolution, and adjusting the MIPI working frequency of the display screen according to the third MIPI working frequency. In this way, the MIPI working frequency of the display screen can be dynamically adjusted without changing the hardware design of the electronic device, so that the MIPI of the display screen works in a working frequency with less interference to the MIPI of the camera, which eliminates or reduces the interferencewith camera communication, improves the transmission efficiency of captured images, and achieves a better shooting experience.

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.

[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 broadcasts, 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 camera modules, communication modules, audio modules, etc., thus Affects the functional stability of individual modules in electronic equipment

[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
