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 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 kexternal 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 could be placed at each of the four signal line outputs of the  
transmitter in order to lower signal reflections.
