EL240.128.45 Display
The EL240.128.45 thin film electroluminescent (EL) small graphics
display utilizes Planar’s proprietary Integral Contrast
Enhancement (ICE™) technology to achieve unparalleled image
quality without the use of expensive filters. This small graphics
display excels in a wide range of ambient lighting environments
while effectively eliminating the blooming common to other highbright displays.
The display consists of an EL glass panel and control electronics
connected using elastomeric interconnects into a space-saving,
rugged package for easy mounting and includes a DC/DC
converter. The EL240.128.45 is easily interfaced using a built-in
RAiO RA8835A standard LCD controller. Each of the pixels has
an aspect ratio of 1:1 (V:H) and is individually addressable to
clearly display high information content graphics and text.
Features and Benefits
• Excellent visual performance:
High brightness and contrast
Wide viewing angle > 160°
No compensation needed
• Rapid display response < 1 ms
• Space efficient mechanical package
• Low EMI emissions
• Extremely rugged and durable
• Low power (3 W)
• Reliable, long operating life with >100,000 MTBF
• Built-in RAiO RA8835A standard LCD controller
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.
CAUTION: To prevent injury in the event of glass breakage, the use of
an impact resistant shield or a protective overlay should be used on the
viewer side of the display.

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.
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. Mounting surfaces
should be flat to within ±0.6 mm (±.025"). Use all the mounting holes
provided. Failure to do so will impair the shock and vibration resistance of
the final installation.
The EL240.128.45 is a tab mounted display. Use appropriate length
standoffs to assure that screws through the mounting tabs do not
introduce bending stresses into the display. Do not deflect the ECB out of
its normal plane. The EL240.128.45 mounting tabs were designed for a 3
mm screw.
WARNING: These products generate voltages capable of causing
personal injury (high voltage up to 230 Vac ). Do not touch the display
electronics during operation.
Cable Length
A maximum cable length of 600 mm (24 in.) is recommended. Longer
cables may cause data transfer problems between the data transmitted
and the display input connector. Excessive cable lengths can pick up
unwanted EMI.
Cleaning
As with any glass or coated surface, care should be taken to minimize
scratching. Clean the display glass with mild, water-based detergents
only. Apply the cleaner sparingly to a soft cloth, then wipe the display.
Disposable cleaning cloths are recommended to minimize the risk of
inadvertently scratching the display with particles embedded in a re-used
cloth. Particular care should be taken when cleaning displays with antiglare and anti-reflective films.
Avoiding Burn-In
As with other light emitting displays, displaying fixed patterns on the
screen can cause burn-in, where luminance variations can be noticed.
Use a screen saver or image inversion to avoid causing burn-in on the
display.
