摘要： This disclosure provides a touch positioning method and apparatus. The touch positioning method includes: acquiring capacitance values and position coordinates of each first touch electrode and each second touch electrode in a touch screen; for the each second touch electrode, judging whether a capacitance value of the second touch electrode is greater than a first threshold; determining second touch electrodes as target second touch electrodes when judging that capacitance values of the second touch electrodes each is greater than the first threshold; and determining target touch position coordinates according to the capacitance values and position coordinates of the target second touch electrodes as well as capacitance values and position coordinates of first touch electrodes adjacent to the target second touch electrodes.
