Product Profile
The EL320.256–FD7 display is a low power, rugged, electroluminescent (TFEL)
display which replaces the bulky CRT in control and instrument product
designs. It features an integrated DC/DC converter, and its compact
dimensions save space that can allow addition of features or reduction in
overall size. It is designed to function in extreme environments, and its clear
display is viewable under most lighting conditions at wide viewing angles. Its
ease of installation reduces system integration costs.
The EL320.256-FD7 is a 320 column by 256 row flat panel display. The digital
flat panel interface is designed to match the needs of most systems.
The display requires +5 Vdc and +11 to +30 Vdc (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 EL
glass panel with soldered lead frames. The result is a flat, compact, reliable and
rugged display device.

The EL320.256–FD7 display includes a light absorbing ICE ( Integrated Contrast
Enhancement) construction of the display glass. ICE construction significantly
improves the luminance contrast of the display in bright ambient. The ICE also
removes the halo around the lit pixels in dark ambient making the appearance
of each pixel extremely 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. All high voltages required
for display glass access are generated internally.
Display Features
Luminance Control
The luminance 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.
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.
Self Test
When SELFEST jumper (PS1/1) is set, the video data at VID and TVID are
displayed asynchronously without the use of any timing signals.

Optional Filter
The luminance contrast of EL320.256–FD7 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 in
high ambient luminance levels, a circular polarizing filter with anti-reflecting
coating or etch is recommended. This filter will still lower the reflections from
the display background and improve the contrast ratio. Contact Planar for
details.

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 min5 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.
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
EL320.256–FD7 should be mounted using the four M3 corner standoffs. 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.
