DOGM GRAPHIC SERIES
EA DOGM128
The EA DOGM128, a 128x64-pixel graphics display, is a new addition to ELECTRONIC ASSEMBLY’s EA DOGM
series. It, too, has pins that allow it to be mounted quickly and easily. 7 different optional LED backlights are
available. These can be combined with 5 different display technologies, making it possible to have up to around
20 different designs. Designed for compact, handheld devices, this modern LCD series offers a number of benefits
with and without backlighting:
* Extremely compact (55x46 mm) with a large viewing area of 51x31 mm
* Super-flat: 2.0 mm without backlight module, and only 5.8 mm with a b./l. module mounted
* Serial SPI interface (4-wire)
* Single supply +3.0 V or +3.3 V
* Typical power consumption of only 270µA in full operation (white LED backlight from 5mA)
* Easily mounted by soldering
* Wide range of design variants orderable as single units
* Backlighting color changes possible
CONTRAST ADJUSTMENT
The contrast can be set by means of a command for all the displays in the EA DOGM 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 variants are available for individual backlighting: white, yellow/green, green, blue, red, amber and a
full-color version.
There are 3 separate LED paths available for each monochrome backlight that can be switched in parallel or in
series to suit the system voltage. This means that most backlights can be run at either 3.3 V or 5 V.
To operate the backlight, we recommend a
current source (e.g. CAT4238TD) or an
external series resistor to limit the current. This
can be calculated from R=U/I; you can find
the values in the table on the right. To prolong
the life of the backlights, we recommend that
you use a current source.
The operating life of the yellow/green, red and
amber backlights is 100,000 hours. The life
of the white and blue backlights is
considerably shorter. 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 will
immediately destroy the LEDs. Always use a
current source. Please note that derating
applies at temperatures exceeding +25°C.
ASSEMBLING
First, clip the display and backlight modules together by gently pushing the display pins through the corresponding
holes on the backlight module. Then insert the entire module into the socket, or into the soldering holes on the
pcb. The backlight pins (the 2 rows with 3 pins at the bottom) must be soldered on the top side as well to ensure
good contact between the modules.
Important: The display has a protective film on the top and/or the bottom, and there is also one on the
backlight. These must be removed.
Make sure that neither display nor backlight will never come into contact with any kind of liquid like
Fluxer, Cleaner, Water.

APPLICATION EXAMPLES
If an external source of +10.5 ~ +13.5V (does not have to be
stabilized) is available, the charge pump is not needed and
less external components are required.
+3.0V or +3.3V (single supply) operation
requires 9 external capacitors
USB-TEST BOARD EA 9780-2USB
For easy startup, a USB test board is available that can be connected to a PC. A USB cable and Windows
software is supplied with the product. This allows text and images (BMP) to displayed directly on the connected
display. You will find more information on the test board in the EA 9780-2USB
data sheet.
SIMULATION WITH WINDOWS
A simulator window also displays the contents of the display. The software can
simulate all the displays and colors even without the hardware. You can download
the software free from our website:

DATA TRANSFER
Data transfer is unidirectional. That means that data can only be written; it cannot be read again. In contrast to
other displays, a busy query is not necessary with this display. The clock-pulse rate of the SCL line can be up
to 20 MHz, depending on the supply voltage. You will find more detailed information on timing on pages 64 and
65 of the data sheet of the ST7565R controller, which you will find on our website at

12:00 VIEWING ANGLE, TOP VIEW OPTION
If the display is read mostly from above (on the front of a laboratory power supply
unit, for example), the preferred angle of viewing can be set to 12 o’clock. This
rotaties the display by 180°. A slightly different initialization setup
is required for this. Also keep in mind that the leftmost column
(normally numbered as 0) will now change to 4.

TOUCH PANEL EA TOUCH128-1 (OPTIONAL)
An analog touch panel is available as an accessory. It has a self-adhesive material on its rear surface and is
simply stuck onto the display. The connection is made by means of a 4-pin flexible cable for a ZIF connector (e.g.
EA WF100-04S) with a grid of 1.0 mm. Bending radius is defined with min. 5mm. For optimum readability we
recommend that you use a backlight with the display.
Interfacing to a processor can be either done by an external touch panel controller or with a controller that is
featured with analogue input. The touch panel is similar to a potentiometer:
connecting a voltage of e.g. 3.3V to
the pins
Top-Bottom
makes it
possible to read out a voltage on
pin
Left
or
Right
which is linear to
the Y-coordinate of the pressed
point. The X-coordinate will result
when the voltage will be supplied
to
Left-Right
and measurement is
done at
Top
or
Bottom
.
The pinout of the connecting cable
is shown in the drawing.

DIMENSIONS EA DOGM128
Note:
The 6(4) LED pins A1 to A3
and C1 to C3 also have to be
soldered from above to ensure
good contact.
Note:
- LC displays are generally not suited for wave or
reflow soldering. Temperatures of over 80°C can
cause lasting damage.
- The surfaces of the displays and backlights are
protected from scratching by self-adhesive protective
foils. Please remove these before mounting (2 pcs. on
display and 1 pc. on backlight).
- Make sure that either display nor backlight will never
come into contact with any kind of liquid like Fluxer,
Cleaner, Water.
