Contrast Adjustment
Contrast voltage for all displays of EA DIP162-D series is typ. 5V. That means
that for 3.3V operation an additional negative voltage of min. 1.7V is required.
Display modules for -20..+70°C are equipped with an on-board temperature compensation. So
there's no more need for contrast adjustment while operation anymore.
Backlight
Using the LED backlight requires an current source or external current-limiting resistor. Forward
voltage for yellow/green backlight is 3.9~4.2V and for white LED backlight 3.0~3.6V. Please take
care of derating for T
a
>+25°C
Note: Do never drive backlight direct to 5V; immediately damage my happen !
