Claim:
1. A display driver, comprising a plurality of driver stages, each of which comprising a first input end, a second input end, a third input end, a first output end, a second output end, a first transistor, a second transistor, a first controller and a second controller, wherein a source node of the first transistor is electrically coupled to a first power supply, a gate node of the first transistor is electrically coupled to a first node, and a drain node of the first transistor is electrically coupled to the first output end; a source node of the second transistor is electrically coupled to the first output end and a gate node of the second transistor is electrically coupled to the second controller, and a drain node of the second transistor is electrically coupled to a first input end; the first controller is electrically coupled to the second input end and the third input end to provide sampled signals to the first node and the second output end; the second controller is electrically coupled to the first controller and a second power supply, and the first output end of each driver stage is electrically coupled to the third input end of the next driver stage.
