PCI, PCO

These pins control to turn power on/off of the ACX704AKM/BKM when the LCD is turned on/off. Connect PCO

to DC-DC converter that can control power on/off of the ACX704AKM/BKM.

Power-on Sequence

• Raise and fall VDD1 and VDD2 simultaneously (within 10ms)

• Input the input signal∗1 for 1 field (Min.), and then raise PCI.

• After PCI becomes high, latch is performed twice at Vsync. When both of them are high, PCO output is

changed from low to high.

(Turn the power on of the ACX704AKM/BKM at this timing.)

Also, effective screen is displayed after two fields of entire white display from this timing.
