Abstract:
An organic light-emitting display device and a method of driving the display device are disclosed. A pixel circuit used in the organic light-emitting display device includes a first switching transistor, a second switching transistor and a driving transistor. The first switching transistor switches a data voltage in response to a first control signal. The second switching transistor switches a compensation voltage in response to a second control signal. The driving transistor provides an electric current to an organic light-emitting device in response to the data voltage and the compensation voltage.
