Claim Text:
1. A display device comprising: 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 circuit 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 circuit 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, wherein the first data driver transmits a first lock signal to the timing controller when its data transmission with the timing controller is available, and the second data driver transmits a second lock signal to the timing controller when its data transmission with the timing controller is available, and wherein the synchronization unit receives the power management signal and the first and second lock signals from the timing controller, and when the first and second lock signals have a same logic level, outputs the power management signal to the power module.
