Document Type and Number:
WIPO Patent Application WO/2019/023941
Kind Code:
A1
Abstract:
Embodiments of the present application provide a touch position determining method, a capacitive touch device, and a capacitive touch terminal. The method comprises: collecting original sampling data outputted by a detection electrode when a capacitive touch sensor is marked; collecting noise sampling data outputted by the detection electrode when the capacitive touch sensor is not marked; and determining the touch position of a touch object on the capacitive touch sensor according to the original sampling data and the noise sampling data outputted by the detection electrode when the capacitive touch sensor is marked and not marked. The touch position is determined in combination with the noise sampling data and the original sampling data, thereby improving the accuracy of the touch position.
