EA DOGL128-6 GRAPHIC
EA DOGL128-6
The EA DOGL128-6, a 128x64-pixel graphics display, is a new addition to ELECTRONIC ASSEMBLY’s EA DOGL
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 (68x51 mm) with a large viewing area of 64x36 mm
* Super-flat: 2.8 mm without backlight module, and only 6.5 mm with a b./l. module mounted
* Serial SPI interface (4-wire)
* Single supply +3.0 V or +3.3 V or dual power supply +1.8..3.3V
* Typical power consumption of only 320µA 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 DOGL128-6 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 a
higher voltage.
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.

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 2 protective films on the top and the bottom (except the version EA DOGL128L
that does have 1 foil on the top only), 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.

6 and more different backlight colors are available to match equipments design as much as possible. The
most effective and brightest one is the white one EA LED68x51-W.

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.
Power supply voltage for display and logic may be
1.8..3.3V then.
ZIF CONNECTOR EA WF100-04S
As an accessory for the touch panel we do provide
a ZIF connector (4 pins) with pitch 1.0mm (SMD
type). This connector is a „bottom side contact“
type.

SOCKET FOR THE DISPLAY
EA FL-20P provides a 20 pin socket which
matched perfect to the display. Note that 2 pcs.

TABLE OF PROGRAMMING COMMANDS
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 at 3.3V, 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 TOUCH128-2 (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
to read out a voltage on pin
Left
or
the Y-coordinate of the
pressed point. The Xcoordinate will result when the
voltage will be supplied to

USB-TEST BOARD EA 9780-2USB
For easy startup, a USB test board is available that can be connected to a PC. An 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:

ATTENTION
handling precautions!
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.
- Make sure that either display nor backlight will never
come into contact with any kind of liquid like Fluxer,
Cleaner, Water.
