A display panel, comprising:
- an organic light-emitting structure layer comprising a cathode;
- a touch layer disposed on the organic light-emitting structure layer, wherein the touch layer comprises:
- a plurality of touch electrodes disposed on the cathode in a matrix, wherein a coupling capacitance is formed between each of the touch electrodes and the cathode;
- and
- a plurality of touch signal lines, wherein one terminal of each of the touch signal lines connected to one of the touch electrodes;
- and
- a driver chip disposed at one side of the display panel, wherein the other terminal of each of the touch signal lines is connected to the driver chip, and the driver chip is configured to acquire a signal of the coupling capacitance and determine whether a touch operation exists according to a change of the signal of the coupling capacitance.
