Note 4) Contrast adjust voltage “Vcon-VW is transformed into the LCD driving voltage “V,” by following
circuit built in the LCD module.
LCD driving voltage “V,, ” is adjusted automatically according to the change of ambient temperature
range by the temperature compensation circuit.
Temperature compensation circuit built in LCD module have been set obtain the optimum contrast under
following driving conditions.;
Take care that voltage for optimum contrast is changed under the different conditioa
Frame frequency : 75 Hz, Duty ratio : 11244 (an odd number frame), Ta = 25 “c
XThe above is the condition of the module settin?. not the electrical characteristics.
