Abstract
Disclosed are a pixel circuit and an organic light emitting display device using the same. The pixel circuit includes a light emitting element configured to include an organic emission cell formed between an anode and cathode of the light emitting element, a driving transistor configured to control emission of light from the light emitting element according to a voltage applied between a gate and source of the driving transistor, a data capacitor configured to include a first terminal and a second terminal; and a switching unit configured to initialize a voltage of the data capacitor during an initialization period, store a threshold voltage of the driving transistor during a threshold voltage storage period, store the data voltage in the data capacitor during a data voltage storage period, and emit light from the light emitting element by using the data voltage stored in the data capacitor during an emission period.
