Abstract
A source driver, an operation method thereof and a driving circuit using the same are provided. The source driver includes a gamma voltage generating circuit, a first voltage buffer and a reference voltage driving circuit. The gamma voltage generating circuit receives an inter reference voltage to provide a first gray level reference voltage corresponding to a first display gray level. The first voltage buffer is used for receiving the first gray level reference voltage to provide a driving voltage. The reference voltage driving circuit is coupled to the gamma voltage generating circuit and the first voltage buffer and used for accelerating rising speed or falling speed of the first gray level reference voltage.
