1Product profile
The EL320.256-FD6 display is low-power, rugged, electroluminescent (TFEL) display. The
display has an integral DC/DC converter and compact dimension save space that allows
addition of features or reduction in overall size. The display is designed to function in extreme
environments, and a crisp display is viewable under most lighting conditions at wide viewing
angles. The display ease of installation reduces system integration costs.
The EL320.256-FD6 is 320 columns by 256 row flat panel display with a resolution of 80 dots
per inch. The pixel aspect ratio is 1:1. The digital flat panel interface is designed to match the
needs of most systems. The display may be driven at frame rates up to 75 Hz.
The EL320.256-FD6 display requires +5 V and +11 V to +30 V (Vcc1, Vcc2) power and 4 basic
signals to operate:
1. Video Data or pixel information (VID)
2. Video Clock, pixel clock, or dot clock (VCLK)
3. Horizontal Sync (HS)
4. Vertical Sync (VS)
2TFEL technology
The display consists of an electroluminescent glass panel and two mounted circuit boards
with control electronics.
Figure 1. TFEL technology
The TFEL glass panel is a solid-state device with a thin film luminescent layer sandwiched
between transparent dielectric layers and a matrix of row and column electrodes. The row
electrodes, in back, are aluminums; the column electrodes, in front, are transparent. The
entire thin film device is deposited on a single glass substrate. The glass panel is mounted to
an electronic circuit assembly board (ECA) with an elastic spacer. The ECAs are connected to
the TFEL glass panel with soldered lead frames. The result is a flat, compact, reliable, and
rugged display device.

The EL320.256–FD6 display includes a dark ICEBrite™ (Integral Contrast Enhancement)
background in the display glass. The ICEBrite background significantly improves the
luminance contrast of the display in bright ambient. ICEBrite also removes the halo around
the lit pixels in dark ambient, making the appearance of each pixel crisp and clear.
In the EL320.256-FD6 display, the 320 column electrodes and 256 row electrodes are
arranged in an X-Y formation with the intersecting areas performing as pixels. Voltage is
applied to both the correct row electrode and the correct column electrode to cause a lit
pixel. Operating voltages required are provided by an integral DC/DC converter.

3.4 Control basics
The TFEL panel has 320 transparent column electrodes crossing 256 row electrodes in an X-Y
fashion. Light is emitted when an AC voltage is applied at a row-column intersection. The
display operation is based on the symmetric, line-at-a-time data addressing scheme, which is
synchronized by the external VS, HS, and video clock input signals. The signal inputs are
HCT-compatible with 100 Ω series resistors.
3.5 Power input
The input voltages needed are the +5 V input (Vcc1) for the logic and the +11 V…+30 V input
(Vcc2) for the DC/DC converter generating all internal high voltages.

4Display features
4.1 Low power mode
The power consumption of the display is possible to be reduced typically to 3 W by using the
low power mode. This mode is selected either with the _LP jumper (PS1/3) or temporarily
with the _LOWPOW control input (J2/4). The _LP jumper overrules the control input.
Low power mode is selected when the _LP jumper is set or the _LOWPOW input is pulled
LOW. When _LP is open and _LOWPOW is HIGH of left disconnected, the display has its
normal brightness. This function slightly reduces the contrast and average brightness of the
display.
4.2 Two-bits-parallel
For reduction of data clock frequency, it is possible to input the data of two pixels per pixel
clock. This feature is selected with the DCONFIG jumper (PS1/2). If the jumper is set, data
for even columns is input in VID and data for odd columns is input in TVID. If the jumper is
open, data is input normally to VID only.
4.3 Brightness control
The brightness of the display can be adjusted from below 10% up to full brightness by a 50
kΩexternal logarithmic potentiometer between the LCa and LCb control inputs (J2/1 and /2).
The control function is achieved by sinking a small current from LCa to LCb (when open, the
voltages are at 5 V and 0 V respectively).
If the two inputs are left disconnected, the brightness is at its maximum level.
4.4 Self-test
The operation of the display can be easily tested using the two self-test features.
When the SELFEST jumper (PS1/4) is set, the video data at VID and TVID are displayed
asynchronously without the use of any timing signals.
When only supply voltages without any video data are input, the display starts scanning with
all pixels except the leftmost half of the topmost row on.

CAUTION: The ambient temperature of the display should not be allowed to exceed the
environmental specifications (see page 9). In most applications, an air gap of a minimum of
5 mm is recommended (see mechanical drawings). Some applications may require, however,
a larger air gap or cooling of the display unit in the system. Note that this may slightly
increase the total depth of the design.
CAUTION: In order to ensure mechanical compatibility with future revisions of the display, it
is highly recommended not to intrude in the component envelope by any part of the customer
application.
WARNING: The product generates potentially dangerous voltages capable of causing
personal injury (high voltage pulses up to 195 Vac). Do not touch the display electronics
during operation!

7Installation and handling
The product should be mounted using the M3 insert nuts on the ECA. Beside the four corner
nuts, it is recommended to use also the center nut in the mounting if the vibration or shock
stress is severe.
Before touching the display, necessary precaution must be taken to prevent application of
static charges on the display from the operator or tools.
The display is made of glass material and should be handled with proper care. Do not drop
the display or allow hard objects to strike its surface.
NOTE: For trouble-free data transfer, a maximum cable length of 300 mm (12 in.) from data
transmitter to display input connector is recommended. If longer cables up to 2 m (80 in.)
length are needed, a serial resistor of approximately 100 Ωcould be placed at each of the
four signal line outputs of the transmitter in order to lower signal reflections.

8Description of warranty
Seller warrants that the Goods will conform to published specifications and be free from

Warranty repairs shall be warranted for the remainder of the original warranty period. Buyer
shall report defect claims in writing to seller immediately upon discovery, and in any event,
within the warranty period. Buyer must return goods to seller within 30 days of seller’s
receipt of a warranty claim notice and only after receiving seller’s return goods authorization.
Seller shall, at its sole option, repair or replace the goods.
If goods were repaired, altered or modified by persons other than seller, this warranty is
void. Conditions resulting from normal wear and tear and buyer's failure to properly store,
install, operate, handle or maintain the goods are not within this warranty. Repair or
replacement of goods is seller’s sole obligation and buyer's exclusive remedy for all claims of
defects. If that remedy is adjudicated insufficient, Seller shall refund buyer's paid price for
the goods and have no other liability to buyer.
All warranty repairs must be performed at seller’s authorized service center using parts
approved by seller. Buyer shall pay costs of sending goods to seller on a warranty claim and
seller shall pay costs of returning goods to buyer. The turnaround time on repairs will usually
be 30 working days or less. Seller accepts no added liability for additional days for repair or
replacement.
If seller offers technical support relating to the goods, such support shall neither modify the
warranty nor create an obligation of seller. Buyer is not relying on seller’s skill or judgment to
select goods for buyer’s purposes. Seller’s software, if included with goods, is sold as is, and
this warranty is inapplicable to such software.
SELLER DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT
LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.

Beneq Oy is committed to continuous improvement. As part of this process we are fully in
support of EU directive 2011/65/EU, the Restriction of Hazardous Substances, commonly
known as RoHS II or RoHS Recast, which, compared to RoHS, keeps the restrictions on the
original six hazardous substances, including lead (Pb) in electronic equipment. It also
expands these restrictions to previously exempted categories including medical devices and
monitoring and control instruments.
Beneq part number with an “LF” suffix designation indicates RoHS compliance, as shown on
the part number label affixed to the display and on the box containing the display.
