Organic light emitting display using a current sink driver to set the voltage of the driving transistor

摘要

A pixel including an organic light emitting diode for use in an organic light emitting display device and a method for driving the display device. First and second transistors are coupled with a current supply line and are turned-on by a scan signal supplied to a scan line to charge a first capacitor to a voltage corresponding to a current through the current supply line. A third transistor supplies a current corresponding to the voltage charged in the first capacitor to the diode. A fourth transistor coupled to a data line is turned-on by a select signal supplied to an address line to charge a second capacitor to a voltage corresponding to a current flowing in the data line. A fifth transistor is coupled between the third transistor and the diode, and is turned-on/off according to the voltage charged in the second capacitor.
