EA OLED SERIES
With its EA OLED series ELECTRONIC ASSEMBLY launched worldwide the first display family with OLED-
technology for direct mounting and soldering. In comparison to standard displays there’s no FFC/FPC
cable/connector that may lose contact, this OLED series will be soldered directly or put into a standard 2.54
mm precision socket.
It is designed for compact handheld equipment and provides a lot real advantages:
- Extreme compact with a large viewing area
- Super flat with 2.4 mm (without frontal protection glass)
- SPI and I²C interface
- Simple mounting with direct soldering
- Ex stock available from 1 pc. off
- Long life time (>50,000h for yellow)
- Wide temperature range (-40..+80°C)
- Fast response time (10µs), no afterglow
VERSIONS
The EA OLEDS102-6 is available in 3 different versions:
EA OLEDS102-6GGA / Allround
This module is perfect for rough environment. An additional frontal glass protects the display against scratch,
shock and UV light. Thanks to its integrated polariser there’s no need for an additionally smoked glass.
EA OLEDS102-6LGA and -6LWA / Flat
This module is the standard module and does fit for the most applications. The flat design (2.4 mm) makes
the display perfect for smallest equipment. The background is always deep black for best contrast.
COLORS (CUSTOM MADE)
The standard colors are yellow and white.
The flat version EA OLEDS102-6LGA is on customers request available in 3 more colors. The minimum order
quantity is 10,000 pcs., lead time is about 20 weeks. Samples are available on request.
Interface and software are 100% compatible. The yellow color provides highest brightness and longest life
time.

DATA TRANSFER 4-WIRE SPI (8 BIT)
Data transmission for SPI is
unidirectional, that means that
data can only be written,
there’s no data read option.
Selection for writing data or
command is done with the
D/C line. A busy check is not
necessary at all. Clock rate
may be up to 10 MHz. Data
transmission is based on SPI
mode 3, MSB first. For more
details please refer to the
controllers data sheet SSD1306B.
DATA TRANSFER 3-WIRE SPI (9 BIT)
Data transmission for SPI is
unidirectional, that means
that data can only be written,
there’s no data read option.
Selection for writing data or
command is done with the
first bit of the 9 bit data
transfer. A busy check is not
necessary at all. Clock rate
may be up to 10 MHz. Data transmission is based on SPI mode 3, MSB first (9 bit). For more details please
refer to the controllers data sheet SSD1306B.
DATA TRANSFER I²C
The I²C mode provides a bi-directional data transmission: That means that data can be written and read. With
the pin SA0 the I²C address can be changed (L: 0x78 or 0x3C, H:0x7A or 0x3D). So up to 2 displays may be
driven on 1 bus. The clock rate may be up to 400 KHz. Please make sure when defining the pull-up resistors
that the internal resistance of the display is 600..1000 . This affects the low level when reading data and
ACK bit.
Attention: When reading data, after the command for page- or column address there need to be a dummy
read (discard the first byte).
Control byte: Co (Continuation bit) = 0 Display data do follow; 1 refer D/C bit

GRAPHIC RAM
The EA OLEDS102-6 comes with an integrated display RAM. Each byte represents 8
dots. For more details please refer to the controllers data sheet SSD1306B, available

ACCESSORY: SOCKET EA FL-14P
Using a 14-pin socket makes the display replaceable and
adapts the height. Those socket may also be soldered
automatically by wave soldering or reflow process. Each display
requires 2 pcs.
ACCESSORY: ZIFF CONNECTOR
EA WF100-04S
The ZIFF connector matches perfect to the touch panel
EA TOUCH128-1. It provides 4 pins with 1.0 mm pitch.
Connection is bottom contact.
Top contact version is called EA WF100-04T.

ACCESSORY: TOUCHPANEL EA TOUCH102-1
As an accessory there is an analogue touchpanel available. It
comes with a self-adhesive glue on its rear side. Connection is
done via FFC, pitch 1.0 mm. Any standard ZIFF connector can
be used (e.g. EA WF100-04S). Bending radius is minimum 5
mm. 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. 3.3 V 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. For
connection there is a ZIF connector with pitch 1 mm, e.g. EA
WF100-04S.
Only in combination with the EA OLEDS102-6GGA.
TOUCH PANEL EA TOUCH102-17C1 (PCAP, CAPACITIVE)
As an accessory we provide a suitable, capacitive touch panel (PCAP). It comes
already with controller (GT5663) and integrated I²C bus. It supplies the
coordinates in double resolution 204x128. The line INT shows, if data are
available to be read out. The I²C bus address is 0xBA (0x5D). For connection
there is a ZIF connector with pitch 1.0 mm, e.g. EA WF100-06S.

ATTENTION
handling precautions!
Note:
- OLED displays are generally not suited
for wave or reflow soldering. Temperatures
of over 80°C can cause lasting damage.
- The surfaces of the displays are protected
from scratching by self-adhesive protective
foil. Please remove before mounting
