VCOM_OUT
Common voltage output
of LCD panel.
Adjustment is possible
by the 3-wire serial
interface setting.
O
5.5 to 7.5V
Demultiplexed output of
AC inverse driven video
signals.
Can be directly
connected to the LCD
panel.
O
1.5 to 13.5V
SID_OUT
Precharge waveform
output.
Adjustment is possible
by the 3-wire serial
interface setting.
This pin cannot directly
drive the LCD panel, so
input to the LCD panel
through a buffer.
O
1.5 to 13.5V
FRINV
Input for switching the
output polarity to
inverted or non-inverted
relative to the LCD
panel AC drive inversion
timing (FRP) pulse.
