Abstract

An organic light emitting diode display comprising: a substrate; a scan line (121) on the substrate for transferring a scan signal; an initialization voltage line (124) on the substrate for transferring an initialization voltage; a data line (171) crossing the scan line and for transferring a data signal; a driving voltage line (172) crossing the scan line and for transferring a driving voltage; a switching thin film transistor (T2) coupled to the scan line and the data line; a driving thin film transistor (T1) coupled to a switching drain electrode of the switching thin film transistor; an organic light emitting diode (OLED) electrically coupled to a driving drain electrode of the driving thin film transistor; a light emission control thin film transistor (T6) between the driving drain electrode and the OLED; and a bypass thin film transistor (T7) between the initialization voltage line and a light emission control drain electrode of the light emission control thin film transistor; wherein the bypass thin film transistor transfers a portion of a driving current transferred by the driving thin film transistor according to a bypass control signal transferred by a bypass control line.
