Claim 21:
22. A method of driving a display device including a light-emitting device, a first transistor, and a second transistor connected between the first transistor and the light-emitting device and including a gate electrode which receives an emission control signal, the method comprising:
determining whether an operation mode is a variable frequency mode;
determining whether a driving frequency is a second frequency lower than a first frequency; and
a light emission driving operation including:
setting a pulse width of the emission control signal to a first value during an active period when the operation mode is the variable frequency mode and the driving frequency is the second frequency; and
setting the pulse width of the emission control signal to a second value different from the first value during a blank period,

wherein, when the driving frequency is the second frequency, one frame includes the active period and the blank period.
