MIPI Display Interference Control for RF Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen mobile phones experience radio frequency interference due to the integration of the display screen's driver chip into the antenna clearance area, leading to low total isotropic sensitivity (TIS) of the antenna, particularly in game scenes where electromagnetic interference between the radio frequency system and the display screen affects communication stability.
Innovation Solution
An electronic device detects electromagnetic interference in game scenes and employs a real-time interference control strategy to reduce or eliminate the interference between the mobile industry processor interface (MIPI) of the display screen and the radio frequency system, by selecting target frequencies or switching communication channels to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display screen's driver chip is integrated into the antenna clearance area to achieve full-screen mobile phones, then the screen area is improved, but radio frequency interference occurs and antenna sensitivity deteriorates
Solution Approach 1:
The patent implements dynamic frequency adjustment of the MIPI interface based on real-time detection of radio frequency interference. The system continuously monitors interference levels and dynamically changes the MIPI frequency to avoid conflicting with radio frequency signals, thereby resolving the contradiction between full-screen integration and antenna performance
Solution Approach 2:
The patent changes the operating parameters of the MIPI interface by adjusting its frequency based on detected radio frequency interference conditions. This parameter adjustment allows the system to maintain full-screen display functionality while minimizing electromagnetic interference with the antenna system
2Reliability
If the MIPI frequency is adjusted to avoid radio frequency interference, then communication stability is improved, but the complexity of frequency coordination increases
Solution Approach 1:
The patent implements a feedback mechanism where the system detects radio frequency interference levels and automatically adjusts the MIPI frequency in response. This closed-loop control simplifies the frequency coordination process by using real-time feedback to guide frequency selection, rather than requiring complex pre-coordination between systems
Solution Approach 2:
The system performs self-adjustment of the MIPI frequency based on detected interference conditions, without requiring external intervention or complex coordination protocols. The radio frequency system and display system autonomously resolve their own interference issues through this self-service mechanism

AI summary
A method for electromagnetic interference control and related devices are provided. The method includes the following. In response to detecting that an electronic device is in a preset scene, electromagnetic interference between a radio frequency system and a display screen of the electronic device is detected, where the preset scene includes a game scene. In response to the detected electromagnetic interference, a real-time requirement of the preset scene is determined. An interference control strategy adapted to the real-time requirement of the preset scene is obtained. Electromagnetic interference of a mobile industry processor interface (MIPI) of the display screen to the radio frequency system is reduced or eliminated based on the interference control strategy. By adopting technical solutions of the disclosure, electromagnetic interference for the electronic device in the game scene can be reduced or eliminated, thereby improving stability of communication of the electronic device.
