Abstract
A method and apparatus for determining a reference value of a touch screen, and an electronic terminal thereof are provided. The method includes: determining a candidate reference value of a touch screen according to an original reference value and a reference fitting relationship of the touch screen, wherein the reference fitting relationship is determined according to the original reference value of the touch screen and a capacitance value of a capacitor node on the touch screen in a first frame; correcting the candidate reference value; and determining a stable reference value of the touch screen according to the corrected candidate reference value. According to embodiments of the present disclosure, the candidate reference value is closer to the actual capacitance reference, such that accuracy of the determined stable reference value is ensured as much as possible.
