CONTRAST ADJUSTMENT
The contrast can be set by means of a command for all the displays in the EA DOG series. The contrast setting of thedisplay 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
3 different variants are available for individual backlighting:white, amber and a duo-color green/red version.
There are 2 separate LED paths available for eachmonochrome backlight that can be switched in parallel orin series to suit the system voltage. This means that mostbacklights can be run at either 3.3 V or a higher voltage.
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 canfind the values in the table on the right. To prolong the lifeof the backlights, we recommend that you use a currentsource.
The operating life of the amber and green/red backlights
is 100,000 hours. The life of the white backlight isconsiderably shorter. We recommend that you dim theseor switch them off whenever possible.
Important:
Do 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 notethat derating applies at temperatures exceeding+25°C.

APPLICATION EXAMPLE
3 additional capacitors are required for +2,5V..+3.3V operation.
Current consumption typ. 250µA

DATA TRANSFER
Data transfer is unidirectional. That means that data can only be written; it cannot be read again. In contrast to otherdisplays, a busy query is not necessary with this display. The transmission follows SPI-mode 3, with MSB first.
The clock-pulse rate of the SCL line can be up to 33 MHz at 3.3V, depending on the supply voltage. You will find moredetailed information on timing on page 41 of the datasheet of the UC1701x controller, which you will find on ourwebsite at http://www.lcd-module.de/eng/pdf/zubehoer/uc1701.pdf

it is easy to generate for example Cyrillic, Greek and Arabicfonts.
The preview function shows immediately the size and style insimulation window.
When the testboard EA 9780-2USB is connected to the USB
port, you can see the character (or any predefined text) liveon the display !
No need to say that the export function generates a C- andBasic source code as an include file to your software.

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 preferredangle of viewing can be set to 12 o’clock. This rotaties the display by 180°. A slightly different initialization setup isrequired for this. Also keep in mind that the leftmost column (normally numbered as 0) will now change to 30.

USB-TEST BOARD EA 9780-2USB
For easy startup, a USB test board is available that can be connected to aPC.A USB cable and Windows software is supplied with the product. Thisallows text and images (BMP) to displayed directly on the connected display.
You will find more information on the test board in the EA 9780-2USB datasheet.
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 candownload the software free from our website. Note that all functions of thesimulation software do run also without the USB board.

TOUCH PANEL EA TOUCH102-1 (OPTIONAL)
An analog touch panel is available as an accessory. It has a self-adhesive material on its rear surface and is simply stuck
onto the display. The connection is made by means of a 4-pin flexible cable for a ZIF connector (e.g. EA WF100-04S)with a grid of 1.0 mm. Bending radius is definedSpecification

ATTENTIONhandling precautions!

MOUNTING / ASSEMBLINGFirst, 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. Thebacklight pins (4 pins at the bottom) must be soldered on the top side as well to ensure good contact between themodules.
Important:- The display and the backlight do have in summary 3 protective films. There are some on the top and the bottom of
the display and also one on the backlight. These must be removed.
- LC displays are generally not suited for wave or reflow soldering. Temperatures of over 80°C can cause lastingdamage.
- Make sure that either display nor backlight will never come into contact with any kind of liquid like Fluxer, Cleaner,
Water.
