A power adapter control method is provided. The method includes: obtaining a scanning frequency of the TP and a strength of common mode noise generated by a power adapter at the scanning frequency of the TP; determining whether the strength of the common mode noise is greater than or equal to a preset threshold; and when the strength of the common mode noise is greater than or equal to the preset threshold, adjusting a working frequency of a control IC of the power adapter, so that a strength of common mode noise newly generated by the power adapter at the scanning frequency of the TP is less than the preset threshold. The embodiments of the present invention are used for a process of reducing interference of the common mode noise to the TP.

Power adapter control method and control apparatus

An anti-interference method and apparatus for a touch panel relate to the communications field and improve accuracy of switching an operating frequency by the touch panel. The anti-interference method for the touch panel includes obtaining an operating frequency of a charging adapter and a jitter frequency of the charging adapter, and calculating, using a preset algorithm based on the operating frequency and the jitter frequency, a low-noise interval in which the touch panel is to operate such that the touch panel obtains the low-noise interval, and switches an operating frequency of the touch panel to a frequency in the low-noise interval when interference to the touch panel exceeds a preset range. The low-noise interval is a frequency interval in which the touch panel is to operate when the interference to the touch panel is within the preset range.

Anti-interference method and apparatus for touch panel

An interference prevention apparatus includes a control module configured to send a working signal to the interference prevention module. An interference prevention module is configured to receive the working signal and to control a working state of a first component. The first component is connected to the control module by a first connection wire. The first connection wire is divided into at least two segments by an interference prevention material, which is connected to ground.
