Abstract
The present invention provides a source driver for driving a light emitting diode panel. The source driver includes a buffer including an output terminal; and a plurality of driving circuits coupled to the buffer. Each of the plurality of driving circuits includes a constant current transistor including a gate controlled by a node voltage of the output terminal of the buffer; and a compensation unit for compensating the node voltage of the output terminal of the buffer.
