Abstract
A display apparatus includes a plurality of pixel circuits, each outputting a driving current to an output node connected to an organic light-emitting diode based on a data signal. Each pixel circuit sequentially operate in an anode initialization period, a threshold voltage compensation period, a data write period, and an emission period. The pixel circuits are arranged in in multiple rows and multiple columns, and each pixel circuit includes an anode initialization transistor to output an initialization voltage to the output node based on a first control signal. A first control line connected to the anode initialization transistor of a pixel circuit in an odd row is different from the first control line connected to the anode initialization transistor of a pixel circuit in an even row.
