EL480.240-PR2 Display

The EL480.240-PR2 thin film electroluminescent (EL) display is a low
cost, high performance alternative to industry-standard quarter-VGA
LCDs. The EL480.240-PR2 utilizes Planar’s proprietary Integral Contrast

and Brightness Enhancement (ICEBrite™) 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 high-bright displays.

The display consists of an EL glass panel and control electronics
assembled into a space-saving, rugged package for easy mounting.
The EL480.240-PR2 is easily interfaced using standard 4-bit LCD control
signals. Each of the 115,200 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°

• Rapid display response < 1 ms

• Space efficient mechanical package

• Low EMI emissions

• Extremely rugged and durable

• Reliable, long operating life with > 100,000 MTBF

• 4-bit LCD-type interface

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
(±0.25"). Use all the mounting holes provided. Failure to do so will impair the
shock and vibration resistance of the final installation.

The EL480.240-PR2 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
EL480.240-PR2 mounting tabs were designed for a 3 mm screw.

WARNING: These products generate voltages capable of causing personal
injury (high voltage up to 230Vac ). 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.
There are third party products which allow this maximum cable length to be
exceeded. Contact Planar Application Engineering for more information.

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.

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.
