DRIVE CIRCUIT AND DRIVING METHOD FOR FLAT DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the power consumption of a drive circuit of a flat display device without using a high-performance element nor a new component. SOLUTION: There is provided a drive circuit which has a switch circuit capable of outputting scan pulses and sustain pulses to one end of a capacitive load being a display means and after the switch circuit of the drive circuit is turned ON, a power switch circuit is turned ON which supplies a potential from a power line to a 1st signal line for supplying a 1st potential to one end of the capacitive load through the drive circuit and a 2nd signal line for supplying a 2nd potential different from the 1st potential to the one end of the capacitive load through the drive circuit to supply a current while the ON resistance of the switch circuit of the drive circuit becomes sufficiently low. Consequently, loss of current due to the switch circuit of the drive circuit is decreased to reduce the power consumption. COPYRIGHT: (C)2005,JPO&NCIPI
