摘要： 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.

摘要： An organic light emitting display includes a current driving unit, an organic light emitting diode and a memory unit. The current driving unit is employed to provide a driving current according to a driving voltage generated therein. The organic light emitting diode generates a light output based on the driving current. The operation of the memory unit is controlled by a first auxiliary power voltage and a second auxiliary power voltage. When the first auxiliary power voltage is greater than the second auxiliary power voltage, the memory unit is enabled to perform a voltage retaining operation on the driving voltage. When the second auxiliary power voltage is greater than the first auxiliary power voltage, the memory unit is disabled for ceasing the voltage retaining operation.
