摘要： The present disclosure provides a touch positioning method for a touch display device, and the touch display device. When it is detected that a touch operation has been made on a touch panel, whether or not the touch operation is effective is determined. When the touch operation is effective, coordinate information about a touch point are sampled multiple times, so as to acquire a plurality of initial coordinates of the touch point. A grouping calculation is performed on the plurality of initial coordinates of the touch point, so as to determine final coordinates of the touch point.
