PROBLEM TO BE SOLVED: To provide the driving circuit of a current drive type display controlling amounts of currents to be applied to an organic EL(electroluminescence) pixel by using pre-charge structure and its driving method. SOLUTION: This driving circuit is provided with an organic EL pixel, a scan driving part making the pixel emit light by being driven with a scan signal, a first constant current source whose ON/OFF is controlled with a data enable signal to supply a current to the pixel, a second constant current source whose ON/OFF is controlled with a pre-charge signal to supply a current for pre- charging the pixel and control parts controlling amounts of currents of the constant current sources. |
