An organic light emitting diode comprises a third electrode arranged on the side of a multi-layer structure. An electric field is formed by the third electrode and at least one of a first electrode and a second electrode by applying voltage (third voltage) on the third electrode. Electrons and holes can be controlled to converge on a needed light emitting layer by controlling the electric field, and therefore excitons are generated for exciting the light emitting layer to emit light. The organic light emitting diode comprises at least two light emitting layers. Each light emitting layer emits light of one color. The electrons and the holes can be controlled to converge on any light emitting layer by controlling the electric field, and therefore the organic light emitting diode is driven to emit light of different colors. The invention further discloses a driving method of the organic light emitting diode and an organic light emitting display screen.
