Abstract: An organic light-emitting display device and a method of driving the same. The organic light-emitting display device is driven, with one frame being divided into a first period, a second period, a third period, and a fourth period, and includes pixels coupled to scan lines and data lines, a first power supply configured to supply first driving power, wherein the first driving power is set to a first voltage during the first period and the fourth period and a second voltage lower than the first voltage during the second period and the third period, a second power supply configured to supply second driving power. The second driving power is set to a third voltage during the first to third periods and to a fourth voltage lower than the third voltage during the fourth period.
