Abstract: A pixel and an organic light-emitting diode (OLED) display having the same are disclosed. In one aspect, a pixel includes an OLED including an anode and a cathode and configured to emit light corresponding to data signals applied during first and second frame periods. Each of the first and second frame periods includes a first discharge period and a light-emitting period subsequent to the first discharge period. The pixel also includes a pixel circuit configured to control light emission of the OLED, apply a first voltage to the anode during the light-emitting period, apply a second voltage to the cathode, the second voltage having a voltage level less than that of the first voltage, and apply a third voltage to the anode so as to discharge the anode during the first discharge period. The second voltage has different voltage levels during the first and second frame periods.
