Abstract: An organic light-emitting display apparatus includes a plurality of color pixels. Each of the color pixels includes an organic light-emitting diode (OLED), a driving transistor to control current to the OLED, and a compensation transistor connected between an anode electrode of the OLED and a gate electrode of the driving transistor. The compensation transistor turns on based on a compensation control signal. The compensation control signals for different color pixels have different on-times.
