Abstract
A display device includes: a first partial emission driver configured to provide first emission control signals to a first partial panel area of the display panel, and a second partial emission driver configured to provide second emission control signals to a second partial panel area of the display panel; and a power management block configured to: provide a first voltage and a second voltage to the emission driver, in response to the first partial emission driver generating the first emission control signals; and provide a third voltage and a fourth voltage to the emission driver in response to the second partial emission driver generating the second emission control signals; and an emission control block configured to receive the first voltage and the second voltage from the power management block and to provide a first clock signal and a second clock signal to the emission driver.
