Abstract
A display driver comprises a plurality of driver stages. For each stage, a source node of a first transistor is coupled to a first power supply, a gate node is coupled to a first node, and a drain node is coupled to a first output end. A source node of a second transistor is coupled to the first output end and a gate node of is coupled to a second controller and a drain node is electrically coupled to a first input end. The first controller is coupled to a second input end and a third input end to provide sampled signals to the first node and a second output end. The second controller is coupled to the first controller and a second power supply. The first output end of each driver stage is coupled to the third input end of the next driver stage.
