Abstract
An organic light-emitting display device and a method of driving the same are disclosed. The organic light-emitting display device includes a display panel including sub-pixels, a power supply configured to output a voltage for driving the sub-pixels, a selective driver configured to generate a control signal to selectively drive a drive transistor of the sub-pixels between first and second driving schemes, wherein the drive transistor is driven in a saturation region in the first driving scheme, and is driven in a linear region in the second driving scheme, and a gamma change driver configured to change a gamma based on the driving scheme selected by the selective driver.
