Abstract
The present application provides a method for determining a touch position and a touch control chip. The method includes: determining a variation caused by a noise to raw data of a capacitive touch screen; performing noise processing on a first raw value set of the capacitive touch screen according to the variation caused by the noise to the raw data of the capacitive touch screen, to obtain a first processed data set; and determining a touch position on the capacitive touch screen according to the first processed data set. The method for determining a touch position and the touch control chip provided by the present application contribute to improving accuracy of the touch position.
