Pixel and organic light-emitting display device including the same

An organic light-emitting display device comprising:

• pixels disposed at intersections of data lines, scan lines, and sensing control lines, each of the pixels including an organic light-emitting diode;
• a sensor configured to sense electrical characteristics of each of the pixels during a sensing period, and extract electrical characteristic information therefrom;
• and
• a converter configured to receive first data and generate second data based on the first data using the electrical characteristic information,
• wherein a pixel coupled to an i-th scan line (i is a natural number) and a j-th data line (j is a natural number) among the pixels comprises:
• a first transistor configured to control, in response to a voltage of a first node, current flowing from a first driving power source to a second driving power source that is coupled to a second node via the organic light-emitting diode;
• a second transistor coupled between the j-th data line and the first node, and configured to be turned on when a first scan signal is supplied to the i-th scan line;
• a storage capacitor coupled between the first node and the first driving power source;
• and
• an auxiliary capacitor coupled between the first driving power source and the second node.
