Abstract: A source driver and an operation method thereof are provided. The operation method includes following steps. A data signal is provided to the source driver. The operating current of the source driver is reduced to an abnormal operating level in period from the source driver is reset to before a pixel data of the source driver is appeared in the data signal. The operation current of the source driver is restored to a normal operating level when the pixel data of the source driver is appeared in the data signal.
