Organic light emitting display device and method of driving the same

A method of driving the organic light emitting display device comprising:

• a plurality of pixels defined on a flexible substrate;
• an organic light emitting diode disposed on each of the plurality of pixels;
• a first scan line, a second scan line, an emission signal line, and an initialization voltage supply line extended in a first direction with respect to each of the plurality of pixels;
• and
• a data line and a Vdd voltage supply line extended in a second direction with respect to each of the plurality of pixels,
• wherein each of the plurality of pixels includes:
• a first switching thin-film transistor connected with the first scan line and the data line;
• a second switching thin-film transistor connected with the second scan line and the initialization voltage supply line;
• a third switching thin-film transistor connected with the emission signal line and the Vdd voltage supply line;
• and
• a driving thin-film transistor including a gate electrode connected with the first switching thin-film transistor, a source electrode connected with the second switching thin-film transistor and the organic light emitting diode, and a drain electrode connected with the third switching thin-film transistor, and
• wherein the first scan line and the second scan line are grouped and disposed on one side on a plane of each of the plurality of pixels, and the driving thin-film transistor and the emission signal line are grouped and disposed on another side in each of the plurality of pixels,
• the method comprising:
• applying a pulse signal through the first scan line, the second scan line, and the emission signal line during an initialization period, a sampling period, a programming period, and an emission period,
• wherein during the emission period, the first scan line and the second scan line transfer a low-level signal and the emission signal line transfers a high-level signal.
