Organic light emitting display integrated with touch screen panel

An organic light emitting display, the display comprising:

• a first substrate having pixels and signal lines coupled to the pixels;
• and
• a second substrate on the first substrate to seal the first substrate, the second substrate having sensing electrodes of a touch screen panel on a surface thereof, wherein the signal lines include first and second signal lines, the first and second signal lines being arranged in a direction that intersects the sensing electrodes, the first and second signal lines to receive different signals, respectively, and to function as first and second driving electrodes of the touch screen panel, wherein each of the pixels includes:
• an organic light emitting diode (OLED) coupled between a first power supply and a second power supply;
• a first transistor coupled between the first power supply and the OLED;
• a second transistor coupled between a first electrode of the first transistor and a data line;
• a third transistor coupled between a second electrode of the first transistor and a gate electrode of the first transistor;
• a fourth transistor coupled between the second electrode of the first transistor and an anode electrode of the OLED;
• a fifth transistor coupled between the gate electrode of the first transistor and an initialization driving control line corresponding to a respective one of the first signal lines, the initialization driving control line being coupled to a third power supply that is an initializing power supply;
• a sixth transistor coupled between the anode electrode of the OLED and the third power supply, the sixth transistor having a gate electrode thereof coupled to a scan line corresponding to a respective one of the second signal lines;
• a seventh transistor coupled between the first power supply and the first electrode of the first transistor;
• and
• a storage capacitor coupled between the first power supply and the gate electrode of the first transistor, wherein the initializing power supply applied to the initialization driving control line has a lower level voltage than that of a data signal applied to each of the pixels.

An apparatus, comprising:

• a first signal line and a second signal line coupled to a pixel;
• and
• a sensing electrode adjacent the signal line;
• wherein each of the first and second signal lines form a first plate of a capacitor and the sensing electrode forms a second plate of the capacitor, and wherein a change in capacitance of the capacitor corresponds to detection of a touch on a touch screen panel including the sensing electrode, wherein the first signal line is an initialization driving control line connected to a node between a first transistor and a second transistor in the pixel and the second signal line is a scan line connected to a gate electrode of the second transistor.
