The invention discloses a touch screen scanning data self-adaptive noise control method, which comprises the following steps: S1, completing one-frame scanning on a touch screen, and calculating according to scanning data to obtain original data; s2, performing difference calculation on the original data and pre-stored reference data to obtain difference data; s3, searching a peak value in the difference data and calculating a touch screen coordinate corresponding to the peak value; s4, reporting the touch screen coordinates corresponding to the peak values, and meanwhile, obtaining a peak value distribution diagram and performing feature analysis; s5, judging whether scanning parameters need to be adjusted or not according to feature analysis result; if yes, executing the step S6, and if not, returning to the step S1, and starting the scanning of the next frame; and S6, calculating a new scanning parameter, and starting the scanning of the next frame. According to the invention, scanning parameters can be dynamically modulated according to the noise intensity, and effective balance can be carried out between noise processing and a point reporting rate.
