Claim 14:
15. A driving method of the display panel according to claim 1, comprising:
at a display stage, switching on the first control circuit, switching off the second control circuit, and transmitting, by the pixel driving circuit, a driving current to the organic light emitting diode, electrically connected with the pixel driving circuit, through the first control circuit so as to control the organic light emitting diode to emit light; and
at a detection stage, determining a touch area for fingers on the display panel, controlling the first control circuit in the touch area to be switched off, controlling the second control circuit to emit light, transmitting, by the pixel driving circuit, the driving current to the micro light emitting diode, electrically connected with the pixel driving circuit, through the second control circuit so as to control the micro light emitting diode to emit light; receiving, by the photoelectric converter, the light emitted by the micro light emitting diode and reflected by a finger, and outputting a detection signal; and determining fingerprint information of the finger according to the detection signal.
