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
* Typical power consumption of only 140µA 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 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. 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 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.
