Abstract
A source driving circuit and an adjusting method therefor, and a display panel are provided. The source driving circuit includes: a DAC configured to obtain a grayscale value and convert the grayscale value into a grayscale voltage; a differential amplifier having a first input terminal connected to the DAC to obtain the grayscale voltage; a first bias circuit configured to apply a first bias tail current to the differential amplifier; a flip-flop connected to the DAC to obtain the grayscale value and a variation range of the grayscale value; and a second bias circuit connected to the flip-flop and configured to apply a second bias tail current to the differential amplifier in response to the variation range of the grayscale value satisfying a trigger condition.
