Pixel circuit of an organic light emitting display device and organic light emitting display device including the same

摘要

A pixel circuit according to an embodiment includes: a capacitor; a first switching unit configured to initialize the capacitor in response to a first scan signal received from a first scan line; a second switching unit configured to receive a second scan signal from a second scan line disposed in a first direction from the first scan line, to receive a third scan signal from a third scan line disposed in a second direction opposite to the first direction from the first scan line, and to be turned on in response to one of the second scan signal and the third scan signal that is activated after the first scan signal is activated to store a data signal in the capacitor; and a driving transistor configured to provide a driving current to an OLED in response to the data signal stored in the capacitor.
