CONTRAST ADJUSTMENT

Contrast voltage for all displays of EA DIP122-5 series is typ. -4V. That means that for 5V power supply an

additional negative voltage of min. 4V is required.

Display modules for -20..+70°C (-5HNLED, -5NLW and -5NLA) are equipped with an on-board

temperature compensation. So there's no more need for contrast adjustment while operation anymore.

Furthermore these 3 displays are featured with a superfast STN/FSTN liquid that allows fast resonse even at

very low temperatures: typical response time at -20°C is 2 seconds only.

BACKLIGHT

Driving the backlight requires a current source or an external resistor for current limit. Please take care of

derating for t

LED backlight.

Note: Do never drive backlight direct to 5V; immediately damage my happen !

YELLOW/GREEN - BLUE - AMBER

The blue-white display EA DIP122B-5NLW is best for indoor use with and without ambient light. Reading

the display requires a minimum of backlight with about 15mA.

The yellow/green version EA DIP122-5NLED is especially designed for 24-hour or outdoor applications.

These displays do provide best contrast for all ambient illuminations, even with direct sunlight. No need to

say that these display can be read in darkness when LED backlight is switched on.

This is same for the amber backlighted version EA DIP122J-5NLA.
