Common output signals for character display: COM1 to
COM8 for the first line, COM9 to COM16 for the second
line, COM17 to COM24 for the third line, and COM25 to
COM32 for the fourth line. All the unused pins output
deselection waveforms. During sleep mode (SLP= 1) or
standby mode (STB = 1), all pins output V
CC
level.
Segment output signals for segment icon display and
character display. During sleep mode (SLP = 1) or standby
mode (STB = 1), all pins output V
CC
level.
Common output signal for annunciator display; can drive
display statically between V
and AGND levels; outputs
V
CC
level while annunciator display is turned off (DA = 0).
Segment output signals for annunciator display; can drive
display statically between V
and AGND levels; output V
CC
level while annunciator display is turned off (DA = 0).
V2/V3 are voltage levels for the internal operational
amplifiers; can drive LCD with 1/4 bias when V2 and V3
are short-circuited and with 1/6 bias when they are left
disconnected.
Used for output from the internal operational amplifiers
when they are used (OPOFF = GND); when amplifiers'
driving capability is insufficient, attach a capacitor to
stabilize the output. Especially these capacitors for V1OUT
and V4OUT must be attached in 1/26 duty and 1/34 duty.
When the amplifiers are not used (OPOFF = V
); V1 to V5
voltages can be supplied to these pins externally.
Adjusts the driving capability of the internal operational
amplifiers according to the LCD power supply voltage.
