EA DOGL128

The EA DOGL128, a 128x64-pixel graphics display, is a new addition to ELECTRONIC ASSEMBLY’s EA DOGL

series. It, too, has pins that allow it to be mounted quickly and easily. 7 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 (68x51 mm) with a large viewing area of 64x36 mm

* Super-flat: 2.8 mm without backlight module, and only 6.5 mm with a b./l. module mounted

* Serial SPI interface (4-wire)

* Single supply +3.0 V or +3.3 V or dual power supply +1.8..3.3V

* Typical power consumption of only 320µA 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 DOGL 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

7 different variants are available for

individual backlighting: white, yellow/green,

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

version.

There are 3 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 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 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 2 protective films on the top and the bottom (except the version DOGL128L

that does have 1 foil on the top only), 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.

APPLICATION EXAMPLES

LOW VOLTAGE

If an external source of +10.5..+13.5V (does not

have to be stabilized) is available, the charge

pump is not needed and less external

components are required. Power supply

voltage for display and logic may be 1.8..3.3V

then.

LOW POWER

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

requires 9 external capacitors

ZIF CONNECTOR EA WF100-04S:

As an accessory for the touch panel we do provide a ZIF connector (4 pins) with pitch 1.0mm (SMD type). This

connector is a „bottom side contact“ type.

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 at 3.3V, depending on the supply voltage. You 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.

TOUCH PANEL EA TOUCH128-2 (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

defined with min. 5mm. For optimum readability we recommend

that you use a backlight with the display.

Interfacing to a processor

can be either done by an

external touch panel

controller or with a

controller that is featured

with analogue input. The

touch panel is similar to a

potentiometer: connecting

a voltage of e.g. 3.3V to the

pins Top-Bottom makes it

possible to read out a

voltage on pin Left or Right

which is linear to the Y-

coordinate of the pressed

point. The X-coordinate will

result when the voltage will

be supplied to Left-Right and measurement is done at Top or Bottom.

The pinout of the connecting cable is shown in the drawing.

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 Windows

software is supplied with the product. This allows 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 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:

DIMENSIONS EA DOGL128

Note:

The 6(4) LED pins A1 to A3

and C1 to C3 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.
