Abstract: In one aspect of the invention, a method of driving an OLED display includes providing scan signals and data signals and applying the scan signals to scan lines and the data signals to the data lines, respectively. Each scan signal is characterized with a waveform having a compensation duration and a scan duration immediately following the compensation duration. The waveform has a first voltage and a second voltage periodically and alternately varied from one another defining a period in the compensation duration, and has the first voltage in the scan duration. The period is equal to the scan duration but shorter than the compensation duration. As such, during the compensation duration of a scan signal, pixels of a corresponding pixel row are charged for compensation, and during the scan duration, the data signals are written into the pixels of the corresponding pixel row for driving the OLEDs thereof.
