Abstract:
An organic light emitting display device includes a driving transistor having one electrode connected with a node, and another electrode connected with an organic light emitting element, a first control transistor for receiving a first driving voltage through one electrode, and having another electrode connected with the node, a second control transistor for receiving a second driving voltage through one electrode, and having another electrode connected with the node, and a sensing transistor having one electrode connected between the another electrode of the driving transistor and the organic light emitting element, wherein the sensing transistor is turned on in a sensing period, the first control transistor is turned off in the sensing period, and the second control transistor is turned on in the sensing period.
