Abstract

The invention discloses a method and a system for lowering interference of a terminal display screen. The method comprises the steps of firstly, determining a mobile industry processor interface (MIPI) interference interval of the display screen according to read MIPI frequency of the display screen and MIPI line quantity used by the display screen and stored in a terminal; then, determining an interference frequency point of the display screen according to the MIPI interference interval of the display screen and a frequency domain used by the terminal; and configuring a notching filter for a channel corresponding to the interference frequency point of the display screen in a modulator-demodulator. Through adoption of the method, the interference is prevented at the beginning, a radio frequency signal is prevented from interference of the display screen, the complete machine receiving performance of the terminal is improved, and the method is suitable for practical application.

Description

technical field [0001] The present invention relates to the technical field of terminal display screens, in particular to a method and system for reducing interference on terminal display screens. Background technique [0002] The design of mobile communication terminals such as smart phones is becoming more and more complex, and there are more and more functional modules (such as display screens, cameras, sensors, buttons, etc.), and the interference of each module on the mobile phone communication system is also increasing. The screen is one of the most obvious sources of interference. At present, the way to deal with the interference of the display screen to the radio frequency is to conduct a coupling sensitivity test first. After finding that some channels are interfered and the coupling sensitivity deteriorates, then check the interference source. After confirming that the interference source is the display screen, test the display screen. Process to resolve interfere...
