The EA DOG
L
128, a 128x64-pixel graphics display, is a new addition to ELECTRONIC ASSEMBLY’s EA DOG
L
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 DOG
L
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.

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 2 protective films on the top and the bottom (except the version DOG
L
128L
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.

APPLICATION EXAMPLES
LOW POWER
+3.0V or +3.3V (single supply) operation
requires 9 external capacitors
LOW VOLTAGE
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.

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
http://www.lcd-module.de/eng/pdf/zubehoer/st7565r.pdf
