Abstract: Disclosed is a display device that may include a first data driver and a second data driver, each checking availability of a data transmission with a timing controller upon receiving a power voltage; a synchronization unit that outputs a power management signal when both the first and second data drivers become available for their data transmission with the timing controller; and a power module that supplies a high-potential voltage to the first and second data drivers in response to the power management signal output from the synchronization unit.
