Control input pin for output deselect level
*The input signal is level-shifted
from logic voltage level to LC
drive voltage level.and controls LC drive circuit.
*When set to Vss level “L”, the LC driver output pins (Yi-Ylso) are
set to level Vss.
*While set to “L”,the contents of the shift resister are reset not
reading data. When the DISPOFF function is canceled, the driver
outputs deselect level (VIZ or Vd3), and the shift data is reading
on the falling edge of the LP. That time,if DISPOFF removal time
can not keep regulation what is shown AC characteristics
(Page 24).
the shift data is not reading correctly.
AC signal input for LC driving waveform
*The input signal is level-shifted
from logic voltage level to LC
drive voltage level.and controls LC drive circuit.
.Normally. input a frame inversion signal.
*The LC driver output pin’s output voltage level can be set using
the shift register output signal and the,FR signal.
Table of truth values is shown in 7-2-l.
Mode selection pin
*When set Vss level “L”, Single Mode operation is selected, when set
to voo level “H”, Dual Mode operation is selected.
Dual Mode data input pin
*According to the data shift direction of the data shift register,
data can be input starting from the 81st bit.
When the chip is used as Dual Mode, D17 will be pull-down.
When the chip is used as Single Mode, DI, won’t pull-down.
Segment mode/common mode selection pin
*When set to Vss level “L”, common mode is set.
Not used
*Connect DIO-D16 to Vss or Voo. Avoiding floating.
Not used
l XCK is pull-down in common mode, so connect to Vss or open.
LC driver output pins
*Corresponding
directly to each bit of the shift register,
one level
(Vo,
Viz.
V43,
or Vss )is selected and output.
