the bias voltage used is set by a resistor divider.

-To further reduce the difference between the output waveforms of LC

pins Y, and Yteo, externally connect ViR and Vi,.

ic voltage level to LC

drive voltage level.and controls LC drive circuit.

*When set to VSS level “L”. the LC drive output pins (Y1-Yleo) are

set to level Vss .

*While set to “L”,the contents of the line latch are reset.but read

the display data in the data latch regardless of condition of

DISPOFF. When the DISPOFF function is canceled.the driver outputs

deselect level (V,, or V,,),then outputs the contents of the date

latch on the next falling edge of the LP. That time,if DISPOFF

removal time can not keep regulation what is shown AC

characteristics

(Page 2l).can not output the reading data 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.

l Normally.inputs

a frame inversion signal.

*The LC driver output pin’s output voltage level can be set using

the line latch output signal and the FR signal.

Table of truth values is shown in 7-2-l.

Mode selection pin

*When set to Vss level “L”, 4-bit parallel input mode is set.

*When set to VDo level “HI’, g-bit parallel input mqde is set.

*The relationship

between the display data and driver output pins is

shown in 7-2-2.
