ABSTRACT:
The present invention provides a source driver comprising a shift register, a line buffer for storing a data signal and outputting a buffered data signal, and a level shifter for generating a level-shifted data signal based on the buffered data signal. The line buffer further comprises a charge pump supplying a pumped voltage based on a voltage source and a buffer powered by the pumped voltage and outputting a buffered data signal based on the data signal.
