Abstract: 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.
