CONTRAST

is already adjusted for 5V when shipped out. Once contrast is set to an optimum, internal temperature

compensation circuit provides best contrast allover the whole temperature range of -20..+70°C. An external

contrast adjustment is normally not necessary, but can be done via external potentiometer.

BACKLIGHT

Graphic displays EA DIP128-6 are featured with a low-power LED-backlight. Brightness

can be switched off and adjusted infinitely.

Driving the LED backlight requires a current source or an external series resistor for

current limiting. Forward voltage is between 2.2..2.6V (amber), 3.9..3.6V (white),

3.7..4.1V (green). Maximum supply current is 90mA@+25°C. Operating with 5V we

recommend a limiting resitor for amber of 12 Ohm, for the white one of 24 Ohm and for Amber Backlight

the green one of 15 Ohm. Please take care of derating when used at ta >+25°C.

Attention: Do never drive backlight direct to 5V; this may cause immediately defect !

Note: Blue-white version provide no contrast when backlight is switched off. Reading the display requires a

minimum of backlight with about 15mA.

BLACK&WHITE, BLUE, AMBER, GREEN

The blue-white display EA DIP128-6N5LW is best for indoor use with and without ambient light. Reading the

display requires a minimum of backlight with about 15mA.

Black and white version EA DIP128J-6N5LW and green version are especially designed for outdoor

applications. These displays do provide best contrast for all ambient illuminations, even with direct sunlight.

No need to say that display can be read in darkness when LED backlight is switched on.

This is same for the amber backlighted version EA DIP128J-6N5LA. The

greatest advantage here is the long life backlight.
