The world wide most flexible Display Series

Superflat, Text, Graphic, SPI, various colors

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.

Ultra thin construction

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.

Simulation for Windows

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!

Testboard EA 9780-2USB 

The test board EA 9780-3USB 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.

Character Set and Fonteditor

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.
