摘要： A source driver and a display device having the same are provided. The source driver shares several outputs by using a time division method and has an analog voltage stored in a buffer supplied to each data line multiple times during a horizontal scanning interval. Accordingly, by supplying an analog voltage to a data line a first time in a first activation interval and supplying an analog voltage to a data line a second time in a second activation interval, a target voltage of each pixel may be achieved quickly and accurately.
