CONTROLLER PT6520
Graphic modules of EA DIP122-5 series do have 2 controller PT6520 (or
compatible) built in: One for the left half of display and the other for the right
one. From 61 columns each 0..60 are used only.
ATTENTION
PT6520 do not have any character mode, so all character has
to be set by graphic. Many different fonts are optionally
available on disk with part numer EA DISKFONT1520.
A detailed description for all commands and interface timing
handling precautions!
you will find at the user manual for PT6520

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
>+25°C. Uf for yellow/green backlight is 3.9~4.2V, 2.2~2.6V (amber) and 3.0~3.6V for white
a
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.

Note:
In general LC display are not suitable for wave
soldering and reflow soldering process. An ambient
temperature above 80°C may destroy the display.
