Installation and Handling
Do not drop, bend, or flex the display. Do not allow objects to strike the
surface of the display.
CAUTION: The 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.
Mounting EL Displays
Properly mounted, EL displays can withstand high shock loads as well as
severe vibration found in demanding applications. However the glass panel
used in an EL display will break if subjected to bending stresses, high impact,
or excessive loads.
Avoid bending the display. Stresses are often introduced when a display is
mounted into a product. Ideally, the mounting tabs of the display should be
the only point of contact with the system. Use a spacer or boss for support;
failure to do so will bend the display and cause the glass to break. The
instrument enclosure or frame should not flex or distort in such a way that
during use the bending loads might be transferred to the display. The
EL320.240.36 mounting tabs were designed for a 3 mm screw. Mounting
surfaces should be flat to within ±0.6 mm (±0.25"). Use all the mounting holes
provided. Failure to do so will impair the shock and vibration resistance of the
final installation.
CAUTION: Properly mounted, this display can withstand high shock loads
and severe vibration in aggressive environments. However, the glass panel
used in this display will break when subjected to bending stresses, high
impact, or excessive loads.
To prevent injury in the event of glass breakage, a protective overlay should
be used on the viewer side of the display.
WARNING: These products generate voltages capable of causing personal
injury (high voltage up to 235 Vac ). Do not touch the display electronics
during operation.

Self-Test Mode
The display incorporates a self-test mode composed of two patterns displayed
for approximately 30 seconds each, and then repeated. The patterns are as
follows: Full On and 1 X 1 Checkerboard. The self-test mode is entered by
leaving pin 3 unconnected or pulled high.
Note: Pin 3 must be connected to Ground for normal display operation.

Dimming
There are two standard methods for dimming the EL320.240.36 display. Frame
rate dimming allows the brightness of the display to be lowered proportionally
by reducing the frame rate. Frame rate dimming is performed within the
application by lowering the frame rate of the video input signals. Because
brightness is proportional to frame rate, the display can be dimmed by adding
pauses between every horizontal period.
The lowest useable frame rate (brightness) is dependent on the perceived
flicker of the displayed image, but will most likely be around 60 Hz.
Dimming control circuitry is available on some models of this display. This
feature allows manual analog dimming of the brightness from 100% to
approximately 5% of the full brightness.
For models which feature analog dimming, connect a 100 kohm logarithmic
external potentiometer to the dimming port. Alternatively, an external voltage
or current mode D/A converter may be used to facilitate dimming by sinking a
