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-HB mounting tabs were designed for a 3 mm screw. Mounting
surfaces should be flat to within ±0.6 mm (±0.025"). Use all the mounting holes
provided. Failure to do so will impair the shock and vibration resistance of the
final installation.
CAUTION: 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.

Internal Frame Buffer
This display includes an internal frame buffer. The display frame rate and the
display brightness are independent of user-supplied input data timing. The
display frame rate can be controlled through the digital dimming feature as
described below.
CAUTION: The display includes an internal frame buffer. In order to blank the
display image in the event of system malfunction, pull down the VS signal.
Dimming
There are two standard methods for dimming the EL320.240.36-HB display.
Analog dimming using the J2 dimming connector described on page 7 of this
manual allows for manual dimming from 100% to approximately 5% of the full
brightness. To perform analog dimming, connect a 50 k ohm variable resistor
between LUMA and GND. Alternatively, an external voltage or current mode
D/A converter may be used to facilitate dimming by sinking a maximum of 250
µA (for maximum dimming) from LUMA to GND on the input connector. Open
circuit voltage is 4 V nominal.
The internal scan frequency can be controlled via the LUMC and LUMD inputs.
When LUMC and LUMD are left open, the scan rate is determined by the SCAN
signal (pin 4) on the data input connector. With the combination of LUMC and
LUMD, the following and luminance levels are obtained:

Self-Test Mode
The display incorporates a self-test mode composed of two patterns displayed
at maximum frame rate for approximately 30 seconds each, and then
repeated. The patterns are as follows: 50/50 Checkerboard and Full On. The
self-test mode is entered by leaving pin 3 on J1 unconnected or pulled high.
This pin has an internal pull-up. Connect pin 3 on J1 to Ground for normal
display operation.
