Abstract
A source driver and a compensation method for an offset voltage of an output buffer are provided. The source driver includes a storage element, an output buffer, a sampling unit and a first switch. The output buffer has a first input terminal coupled to the storage element and a second input terminal coupled to an output terminal thereof. The output buffer enhances an input signal of the first input terminal and thereby outputs an output signal via the output terminal. The sampling unit respectively transmits a pixel signal and the output signal to the first input terminal of the output buffer and the storage element during a first sub-period for storing an offset voltage of the output buffer in the storage element. The first switch transmits the pixel signal to the storage during a second sub-period for compensating the pixel signal with the offset voltage stored in the storage element.
