Figure 6 shows a basic circuit configuration of the LCD module. Users who use this part for LCD control
need to consider the followings:
1.
The LCD module in Figure 6 can be controlled by using LCD driver peripherals of A31L12X.
2.
The GDC8310 operates with 3.3V of operation voltage and uses 1/4 Duty 1/3 Bias drive
techniques.
3.
Each of COM and SEG of A31L12X and GDC8310 can be connected by matching them as
shown in Figure 7.
