SOURCE DRIVER AND DISPLAY DEVICE

The present invention can provide a source driver and a display device. The source driver includes a decoder and a buffer circuit, and the decoder is configured to receive the image data and an activation signal, determine a target voltage based on the image data, and select at least one gamma line for generating the target voltage from among a plurality of gamma lines, which are configured to transmit different gamma voltages, respectively, and the buffer circuit includes a plurality of input terminals and configured to be connected to the selected at least one gamma line and generate an output voltage based on at least one gamma voltage obtained from the selected at least one gamma line. The decoder may be further configured to select a gamma line group including the selected at least one gamma line to be connected to the plurality of input terminals of the buffer circuit during a slew period of the buffer circuit in accordance with the activation signal. 可以提供一种源极驱动器和显示装置。所述源极驱动器包括译码器和缓冲电路，所述译码器被配置为：接收图像数据和
