The present invention provides a display panel, a power supply part, and a power control part. The display panel displays an image. The power supply part supplies a power voltage to the display panel. The power control part synchronizes with the operation period of a device driving the display panel, and controls the power supply part. The power control part controls the synchronization of the switching frequency of the power generation transistor of the power supply part with one or more among the synchronization signal of a scan driving part, a data driving part, and a timing control part. So, the safety and reliability of output to the power voltage can be maintained. |
