This is the reference voltage to generate the actual SEG driving voltage.
V
BIAS
can be used to fine tune V
LCD
by external variable resistors.
Internal resistor network has been provided to simplify external trimming
circuit. The following network is sufficient for most applications.
An internal RC filter is provided to filter noise on the V
BIAS
pin. When not
used, it is OK to leave V
BIAS
open circuit. If noise starts to cause
problem, connect a small bypass capacitor between V
BIAS
and V
SS
.
In the OTP version, this pin is disconnected from internal circuit. So,
there is no need to add bypass capacitor for this pin for OTP version.

The resistance of these traces directly affects the driving strength of
SEG electrodes and impacts the image of the LCD module. Minimize
