This display series was specially developed for low-power hand-held applications and for large quantities. For the first time it is possible to operate a standard display at 3.3V! The optionally available LED backlighting can also be run with 3.3V or 5V. The preferred interface is the SPI bus. In the mean time are a lot different character and graphic displays available.

EA DOG series - Very flexible

This new display series

was specially developed for low-power hand-held applications and for small and large quantities. For the first time it is possible to operate a standard display at 3.3V! 5V operation is for the character displays also possible.
The optionally available LED backlighting can also be run with 3.3V or 5V depending on the connections. Variuos types and colors are standard.

Display und LED für 3,3V single supply

Ultra thin construction

With a height of just 2.0(2.8) or 5.8(6.4) mm. And this has been achieved without any special construction, but rather with easily processed pins with a pitch of 2.54 mm.
It is also possible to implement a plug-in design using contact strips.

The latest member: EA DOGS104-A

The brandnew character display comes with 4x10 respectively 2x10 character. With its only 36x28mm it is extreme compact and ideal for 19" racks e.g. with 1 RU.

The character height may be changed by software (4x10 with small font resp. 2x10 with double height). Even as the standard it's equipped with 3 different character sets: with a english, a european and a cyrillic characetr set.

Same as for all displays with DOG family there are different display technologies available together with various colored backlights. For the first time now we also do offer a 3-color backlight with the colors white, green and red - changeable of course.

EA DOGS102W-6 Simulation

Simulation for Windows

A great help for orientation in the "colour-jungle" the DOG-Simulator is an excellent tool: all displays (text and graphic) as well as all different backlight options can be simulated on screen. Free of charge!

test board EA 9780-3USB

The test board EA 9780-4USB

The test board EA 9780-4USB adapt all display with its multiple sockets. Even all modules with and without backlight are supported.

The displays do show the individual text and pictures from simulator immediately - without any development action. In addition to that the backlight can be switched on and off. This makes possible a realistic test operation. Without the need to write software or to create any hardware adaptor. Immediately and as easy as ABC.

Arduino meets DOG

Arduino meets DOG

That's the easy way driving a display: the Arduino concept provides a very good base for such.

Some displays in EA DOG series we do support with all things to bring the display into operation with an Arduino Uno easyly: Sketches, Libraries, Documentation, EAGLE *.brd  and *.sch Files.

We also do provide non-assembled pcb boards.

Here you do find a table as an overview.


Character Set and Fonteditor

With the ordering code EA USBSTICK-FONT a memory stick comes with various character sets, especially made for displays from DOG series.
An import function allows additionally to use Windows fonts. With the FontEditor it is easy to generate for example Cyrillic, Greek and Arabic fonts. The preview function shows immediately the size and style in simulation window. When the testboard EA 9780-2USB is connected to the USB port, you can see the character (or any predefined text) live on the display which is plugged-in!

The export function generates a C- and Basic source code as an include file to your software.
Also included is a converter software for *.bmp files.

Design-In and Support

Additionally to our service, to have a phone call to our development engineers, or to contact them directly by email an technik(at)lcd-module.de we provide some more informations and help. 
Initialisation examples, schematic, information for character set, USB driver you do find at our page SUPPORT.


Simply clip the display and the backlighting unit together and you have up to 23 possible combinations.

Six different colors are available as backlighting:
