Description
Power supply pin
Ground pin
Description
These input pins are used to set the polarity
reversal interval ranging from 2P to 17P.
This is an output pin and the FR signal is
generated from the LCD polarity reverse signal
generator.
This is an output pin and the XFR signal is also
generated from the LCD polarity reverse signal
generator. This signal is a reverse phase from FR
signal.
Description
This input pin is used to generate the charge pump
clock and the polarity reverse signal FR and XFR.
A pulse signal with a period of 1P should be fed
into this pin.
This input pin is used to switch on or off the
display. When it is set to VSS level, the clock and
the operations of the voltage converter will be stop.
The display will be off. When it is set to VDD_PWR
level, the display will be on.
