Note 1) The voltage [VEE-VSS] for obtaining maximum contrast is different in individual modules.
And it change because of temperature.
Therefor it is needed adjusting the voltage [VEE-VSS] for obtain to proper contrast.
Note 2) Under the following condition.;
VDD-VSS=3.3V, VEE-VSS=20.9V, Frame frequency=70Hz, Ta=25”C
Display pattem=Full dots ON
