PINOUT
The EA DO
graphics display, is a new member to
ELECTRONIC
EA DOG series. It also has pins that
allow it to be mounted quickly and
easily.
CONTRAST ADJUSTMENT
The contrast can be set by means of
a command for all the displays in the
EA DOG series. The contrast setting
of the display must be set once by the
software, and is then kept constant
throughout the entire operating temperature range (-20..+70°C), thanks to the integrated temperature
compensation.
LED BACKLIGHT
7 different types are available for individual backlighting:
white, yellow/green, green, blue, red, amber and a full-color
version.
There are 3 separate LED paths available that can be
switched in parallel or in series to suit the system voltage.
To operate the yellow/green (-G), red (-R) and amber (-A)
backlight, an external series resistor can be used to limit
the current. This can be calculated from R=U/I.
To operate the white (-W), green (-E) and blue (-B) backlight,
we recommend a current source (e.g. CAT4238TD) .
The operating life of the yellow/green, red and amber backlights
is 100,000 hours. The white, green and blue backlights we do
provide with long-life LEDs from NICHIA. We recommend that
you dim these or switch them off whenever possible.
Important:
Never connect the backlight LEDs directly to a 5 V/3.3 V
supply as this may immediately destroy the LEDs. Always
use a current limiter. Please note that derating applies at
temperatures exceeding +25°C.
