Abstract

The embodiment of the invention discloses a signal interference processing method and device, and a mobile terminal. The method is applied to the mobile terminal. The mobile terminal comprises a radiofrequency module and a touch module. The method comprises the steps of: obtaining radio frequency enable signals emitted by the radio frequency module and touch scanning signals of the touch module;and if the radio frequency enable signals and the touch scanning signals have signal overlapping on a time domain, the touch scanning signals are regulated to allow the touch scanning signals and theradio frequency enable signals to be staggered on the time domain. According to the embodiment of the invention, the touch scanning signals sent by the touch module are only needed to be regulated toeffectively avoid the signal overlapping of the touch scanning signals and the radio frequency enable signals on the time domain so as to avoid the interference problem caused by the simultaneous working of the radio frequency module and the touch module and ensure the radio frequency performance of the radio frequency module.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a signal interference processing method, device and mobile terminal. Background technique [0002] With the continuous development of terminal technology, mobile terminals (such as mobile phones or tablet computers, etc.) have become an indispensable tool in people's life and work. There are fewer, and most of them are replaced by touch buttons, such as touch screens, fingerprint recognition modules or touch buttons. [0003] At present, for terminal equipment, especially smart mobile terminals, the multi-antenna design of touch screen and radio frequency is the trend. Close to the antenna space (that is, the RF module space). With the increase of radio frequency bands and standards, more antennas and area ratios will be required on terminal equipment. Usually, the working process of the touch module includes frequency components such as 60Hz, 120Hz, 88k...
