Product Profile
The EL320.256-F Series displays are low power, rugged, electroluminescent
(TFEL) displays which replace the bulky CRT in control and instrument product
designs. They feature integral DC/DC converter, and their compact dimensions
save space that can allow addition of features or reduction in overall size. They
are designed to function in extreme environments, and their crisp display is
viewable under most lighting conditions at wide viewing angles. Their ease of
installation reduces system integration costs.
The EL320.256-F6 and –FD6 are 320 column by 256 row flat panel displays 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-F Series displays require +5 V and +11 to +30 V (Vcc1, Vcc2)
power and four 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)
EL Technology
The display consists of an electroluminescent glass panel and two mounted
circuit boards with control electronics.
Figure 1. EL Technology.
The EL 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 aluminium; 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 ECA’s are connected to the
EL320.256-F6 and –FD6 Operations Manual (020-0352-00A)

EL 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 ICE (Integrated Contrast
Enhancement) background in the display glass. ICE background significantly
improves the luminance contrast of the display in bright ambients. ICE also
removes the halo around the lit pixels in dark ambient making the appearance
of each pixel crisp and clear.
In the EL320.256-F Series, 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.

Control basics
The EL 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.
Power Input
The input voltages needed are the +5 V input (Vcc1) for the logic and the
+11…+30V input (Vcc2) for the DC/DC converter generating all internal high
voltages.
Display Features
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 _LP jumper
(PS1/3) or temporarily with _LOWPOW control input (J2/4). The _LP jumper
overrules the control input.
Low Power Mode is selected when _LP jumper is set or _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.
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 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 jumper is open, data is input normally to VID only.
EL320256-F6 and –FD6 Operations Manual (020-0352-00A)
6
Brightness Control
The brightness of the display can be adjusted from below 10% up to full
brightness by a 50 kΩ external logarithmic potentiometer between 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 5V and 0V
respectively).
If the two inputs are left disconnected, the brightness is at its maximum level.
Self Test
The operation of the display can be easily tested using the two self test
features:
When 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 on except the leftmost half of the topmost row.

Optional Filter
The luminance contrast of EL320.256–FD6 is sufficient for operation without
any contrast enhancement. An anti-reflective coating or protecting sheet with
anti-reflective treatment is recommended. For best overall performance of the
–F6 in high ambient luminance levels, a neutral gray circular polarizing filter
with anti-reflecting coating or etch is recommended. This filter will make the
reflecting electrodes of the display darker and will improve the contrast ratio.

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 min 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.
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!
ELECTROSTATIC CAUTION: The Planar display uses CMOS and
power MOS-FET devices. These components are electrostatic sensitive.
Unpack, assemble and examine this assembly in a static-controlled area
only. When shipping use packing materials designed for protection of
electrostatic-sensitive components.

Installation 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 appr.
100 Ω could be placed at each of the four signal line outputs of the
transmitter in order to lower signal reflections.
