    摘要： A display driver is provided. The display driver includes: a plurality of source amplifiers connected to a plurality of source lines of a display panel, wherein one of the plurality of source amplifiers includes an input stage and an output stage configured to output a grayscale voltage to a source line of the plurality of source lines; and a decoder circuit configured to provide at least one of a plurality of gamma voltages to the input stage based on image data. The output stage includes a plurality of unit circuits connected to each other in parallel between the input stage and an output pad connected to the source line. Each of the plurality of unit circuits includes a buffer switch and an output buffer connected to the input stage, and is connected to the output pad through a resistor.
