A display panel having a touch detection function and a control method. The display panel includes a display element and a touch element. The touch element includes a touch scanning chip, a scanning selector connected with the touch scanning chip, and multiple touch electrodes connected with the scanning selector. Wherein, the touch scanning chip outputs a selection signal to the scanning selector in order to selectively connect the multiple touch electrodes to the touch scanning chip such that the touch scanning chip sequentially performs a touch scanning operation; the number of ports of the scanning selector used for connecting the touch electrodes is greater the number of ports used for connecting the touch electrodes to the touch scanning chip. The number of lead wires is reduced to reduce the manufacturing process. A higher touch sampling frequency is realized and a better touch effect is obtained.
