Patent ID: 8797318

Claim:
An organic light emitting diode (OLED) display comprising: an organic light emitting diode (OLED) configured to emit light using a driving current flowing between an input terminal of a high potential driving voltage and an input terminal of a low potential driving voltage; a driving thin film transistor (TFT) including a gate electrode connected to a first node and a source electrode connected to a third node, the driving TFT controlling the driving current based on a voltage between the gate electrode and the source electrode; a first switch TFT configured to switch on or off a current path between a data line and the first node in response to a first gate pulse of a pair of gate pulses; a second switch TFT configured to switch on or off a current path between the third node and the input terminal of the low potential driving voltage in response to the first gate pulse; a third switch TFT configured to switch on or off a current path between a reference voltage supply line and a second node in response to a second gate pulse of the pair of gate pulses; a fourth switch TFT configured to switch on or off a current path between the first node and the second node in response to an emission pulse; an emission TFT configured to switch on or off a current path between the third node and the input terminal of the low potential driving voltage in response to the emission pulse; a first capacitor connected between the second node and the third node; and a second capacitor connected between the first node and the second node.
