Abstract: An organic light emitting diode (OLED) display of the present inventive concept includes: pixels connected to scan lines, data lines, and control lines; a data driver for supplying a data signal to the pixels via the data lines; a scan driver for supplying a scan signal to the pixels via the scan lines; and a control driver for supplying a first control signal to the pixels via the control lines. The control driver feeds back the first control signal supplied to the pixels so as to compensate a ripple voltage included in the first control signal, and generates a compensated first control signal by using the fed-back first control signal.
