EA DOGM132

The EA DOGM132, a 132x32-pixel graphics display, is a new addition to ELECTRONIC ASSEMBLY’s EA DOGM

series. It, too, has pins that allow it to be mounted quickly and easily. 6 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 (55x31 mm) with a large viewing area of 51x15 mm

* Super-flat: 2.0 mm without backlight module, and only 5.8 mm with a b./l. module mounted

* Serial SPI interface (4-wire)

* Single supply +2.4 V or +3.3 V

* T ypical power consumption of only 140µA in full operation (white LED backlight from 5mA)

* Easily mounted by soldering

* W ide 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 DOGM 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

6 different variants are available for individual backlighting: white, yellow/

green, blue, red, amber and a full-color version.

There are 2 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 5 V.

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.

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.

W e 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 a protective film on the top and/or the

bottom, 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.

5 DIFFERENT TECHNOLOGIES

See below for an overview of available technologies, combinations with available backlights and their usability:

6 AND MORE DIFFERENT BACKLIGHTS

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 LED55x31-W .

APPLICATION EXAMPLES

LOW VOLTAGE

If an external source of +9..+12V (does not have

to be stabilized) is available, the charge pump is

not needed and less external components are

required. Supply and logic voltage may be

1.8..3.3V

LOW POWER

+3.0V or +3.3V (single supply) operation

requires 8 external capacitors. Current

consumption typ. 110uA

WIDE RANGE

The operation on +2.4..+3.3V (single

supply) requires 9 external capacitors.

Current consumption is typ. 150uA.

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

@3.3V, depending on the supply voltage. Y ou 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

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.

USB-TEST BOARD EA 9780-2USB

For easy startup, a USB test board is available that can be connected to a PC. A USB cable and W indows software

is supplied with the product. This allows text and images (*.bmp) to be 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:

CHARACTER SET AND FONT EDITOR (ACCESSORY)

With the ordering code EA USBSTICK-FONT a memory stick comes with various character sets, especially made

for this small display EA DOGM132-5. 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 !

No need to say that the export function generates a C- and

Basic source code as an include file to your software.

Included is also a software that is called BitmapEdit. With

that it becomes easy to convert standard *.bmp files into the

EA DOGM132-5 format.

DIMENSIONS EA DOGM132

Note:

The 4 LED pins A1/A2 and

C1/C2 also have to be

soldered from above to ensure

good contact.

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.
