Abstract: A method of driving an OLED display includes: during a scanning period of a first frame, turning off a relay transistor and turning on a switching transistor to enable a second data voltage applied to a data line to be stored in a first capacitor; and during a light emitting period of the first frame, performing an operation to turn on a light emitting transistor and a compensation transistor to enable a voltage into which a first data voltage and a threshold voltage of a driving transistor are reflected to be applied to a second node for enabling the OLED to emit light by a driving current which flows into a driving transistor. The scanning period and the light emitting period temporally overlap each other.
