    Abstract: 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.

    Abstract: A detection substrate and a display device are disclosed. The detection substrate includes an outer detection electrode and an inner detection electrode on a base substrate and insulated from each other. The outer detection electrode has a hollowed portion, and the hollowed portion corresponds to the inner detection electrode. The inner detection electrode includes a body portion and a plurality of protrusion portions protruding from the body portion and extending in directions away from the body portion. The edge of the hollowed portion includes a curved portion, an orthographic projection of the curved portion on the base substrate protrudes into a region between orthographic projections of at least two adjacent protrusion portions of the plurality of protrusion portions on the base substrate, a portion of the orthographic projection of the curved portion is closer to an orthographic projection of the body portion on the base substrate.
