发明名称 Organic light emitting diode display and method of driving the same
摘要 <p>An organic light emitting diode display includes a data line, a gate line that crosses the data line to receive a scan pulse, a high potential driving voltage source to generate a high potential driving voltage, a low potential driving voltage source to generate a low potential driving voltage, a light emitting element to emit light due to a current flowing between the high potential driving voltage source and the low potential driving voltage source, a drive element connected between the high potential driving voltage source and the light emitting element to control a current flowing in the light emitting element depending on a voltage between a gate electrode and a source electrode of the drive element, and a driving current stabilization circuit to apply a first voltage to the gate electrode of the drive element to turn on the drive element and to sink a reference current through the drive element to set a source voltage of the drive element at a sensing voltage and to modify the voltage between the gate and source electrodes of the drive element to scale a current to be applied to the light emitting element from the reference current. </p>
