摘要： Driving method and circuit of an organic light emitting diode, applied to an array of a plurality of organic light emitting diode. The array has several rows and columns of organic light emitting diodes. The row and column corresponding to the organic light emitting selected to illuminate are selected. A first voltage is applied to the selected column, and a second voltage is applied to the selected row. The difference between the first and second voltages is larger than the conducting voltage of the organic light emitting diode, so that the light emitting diode can illuminate. A third voltage and a fourth voltages are applied to other rows and columns which are not connected to the selected organic light emitting diode to provide a reverse bias to all the remaining light emitting diodes.
