EA DOG series - Very flexible

This new display series was specially developed for low-power hand-held applications. 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.


  • extrem compact
  • Text: 1x8 - 2x16 - 3x16, +5V / +3.3V
  • Text: 4x10/2x10 und 4x20, +3.3V
  • 132x32 ... 240x128, +3.3V
  • flat at 2.0 (2.8)mm without backlighting and 5.8 (6.4)mm with backlighting
  • can be soldered directly into the PCB without any further assembly
  • 3.3V or 5V - also for the LED backlighting
  • many different designs which can be implemented as of 1 unit
  • Top. -20..+70°C integrated temperature compensation
  • no minimum quantities, short delivery times

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


Ultra thin construction

With a height of just 2.0 or 5.8 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.

Simulation for Windows

A great help for orientation in "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 !
ea9780 The test board EA 9780-2USB 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.
This is unique on market.


Arduino meets DOG

Arduino 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 9780-3USB 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.
