Abstract: The present disclosure discloses a display panel, a manufacturing method, a driving method and a display device. When the display panel needs to display a normal image, a pixel driving circuit and a first control circuit drive an organic light emitting diode to emit light. When the display panel needs to perform fingerprint detection of a finger, the pixel driving circuit and a second control circuit drive a micro light emitting diode to emit light, so that the light emitted by the micro light emitting diode can be received by a photoelectric converter after being reflected by the finger, the photoelectric converter can output a detection signal, and furthermore, fingerprint information of the finger can be determined according to the detection signal.
