Claim:
1. An operation method of an organic pixel, which includes an interconnection layer on a semiconductor substrate including a pixel circuit, the interconnection layer including a contact and a first electrode, and an organic photo-diode on the interconnection layer, the organic photo-diode having an insulation layer on the first electrode, a stacked structure of an electron donating organic material and an electron accepting organic material on the insulation layer, and a second electrode on the stacked structure, the operation method comprising: receiving a transfer control signal via the first electrode of the organic pixel, the first electrode electrically connected to the insulation layer; and performing a charge accumulation operation, which accumulates photo-charges near the insulation layer formed on the first electrode, and a charge transfer operation, which transfers the accumulated photo-charges to the pixel circuit through the contact separated from the electrode, wherein the charge accumulation operation is performed when the transfer control signal has a first level voltage, and one of a ground voltage and a negative voltage lower than the ground voltage is supplied to the second electrode, and the charge transfer operation is performed when the transfer control signal has a second level voltage lower than the first level voltage, and one of the ground voltage and the negative voltage is supplied to the second electrode.
