Some parametric limits are subject to
Voltage Multiplier
When the voltage multiplier is operated after a reference voltage for
boosting is applied to LCD power supply V
LIN
, a voltage that is three
times as large as V
LIN
pin occurs at the V
L5
pin. Operate the voltage
multiplier after applying a reference voltage for boosting to V
LIN
.
Bias Control
In the LCD power source pins (V
L1
–
V
L5
), a proper level is automati-
cally generated in 1/32 and 1/16 duty ratio. The quality of the LCD
display can be stabilized by connecting the capacitor for smooth-
ness between Vss and these pins.
