10 COMMON, SEGMENT OUTPUT VOLTAGE
The output voltage level of COMMON driver (the SBN6400G) and SEGMENT driver (SBN0064G) is given in Table 20.
The output voltage level of COMMON driver is decided by the combination of AC Frame signal (M) and internal Shift
Register output.
The output voltage level of SEGMENT driver is decided by the combination of AC Frame signal (M), Display Data, and
the Display ON/OFF register.
