Abstract

The invention provides an anti-interference method and device. The method includes: when the screen of the terminal device is in a bright screen state, and the working mode of the terminal device is a dual-frequency point working mode, obtaining the first working frequency corresponding to the LCM MIPI, obtaining the first received signal strength and the second Received signal strength, when the first working frequency is the first threshold frequency, and the first communication frequency point is the first interference frequency point, determine the magnitude relationship between the first received signal strength and the first signal threshold strength, in the first When the received signal strength is less than or equal to the first signal threshold strength, and the second communication frequency point is the second interference frequency point, determine the magnitude relationship between the second received signal strength and the second signal threshold strength, and the second received signal strength If the strength is greater than the second threshold signal strength, the first working frequency is adjusted to the second threshold frequency. The invention can improve the influence of LCM MIPI on communication quality.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular, to an anti-interference method and device. Background technique [0002] With the development and popularization of mobile communication technology, mobile terminals (such as mobile phones, tablet computers, etc.) have become an indispensable part of people's life and work. [0003] With the rapid development and maturity of screen display technology, the application of high-definition display screens in mobile terminals is becoming more and more popular. Moreover, high screen ratio and high-definition display are currently an important indicator for consumers to choose mobile terminals. However, "high screen ratio and high-definition display" have brought great challenges to the design of mobile terminals. The driver IC of LCM (LCD Module, liquid crystal module) is closer to the antenna, and the interference generated by the driver IC is more easily couple...
