Abstract

The display panel includes at least one first touch area group and multiple touch wires; the at least one first touch area group includes two rows and N columns of touch electrodes; and each touch wire is electrically connected to a respective one touch electrode. The display panel further includes a first detection circuit and a second detection circuit; and each touch electrode is separately electrically connected to the first detection circuit and the second detection circuit by a respective one touch wire. The touch short-circuit detection stage includes a first detection stage. The detection method includes providing, at the first detection stage, a short-circuit detection signal for a touch electrode in the first touch electrode row by the first detection circuit; and determining, according to a short-circuit feedback signal generated by the second detection circuit, whether adjacent ones of the touch electrodes located in a same column are short-circuited.
