SOURCE DRIVER CIRCUIT, LATCHABLE VOLTAGE LEVEL SHIFTER AND HIGH-VOLTAGE FLIP-FLOP

摘要

PROBLEM TO BE SOLVED: To provide a latchable voltage level shifter. SOLUTION: The latchable voltage level shifter comprises: a voltage level shifter receiving an original input signal and generating a high voltage signal according to a timing sequence of a first phase control signal; and a high voltage flip-flop, coupled to the voltage level shifter, receiving the high voltage signal and a second phase control signal, latching the high voltage signal according to a timing sequence of the second phase control signal and outputting a high voltage output signal. The latchable voltage level shifter can be used in a source drive circuit so as to reduce the layout area and production cost. COPYRIGHT: (C)2006,JPO&NCIPI
