Abstract
A source driving circuit, a display apparatus and an operation method are provided. The source driving circuit includes a reference voltage generating circuit, a plurality of compensation circuits, a gamma voltage generating circuit and a digital to analog converter. The reference voltage generating circuit is configured to generate a plurality of gamma reference voltages. The plurality of compensation circuits are coupled to the reference voltage generating circuit and configured to generate a plurality of compensated gamma reference voltages according to the plurality of gamma reference voltages and a voltage associated with a common voltage. The gamma voltage generating circuit is configured to generate a plurality of gamma voltages according to the plurality of compensated gamma reference voltages. The digital to analog converter is configured to generate a plurality of data driving voltages corresponding to image data according to the plurality of gamma voltages.
