EL320.240.36-HB Quarter-VGA Display

The EL320.240.36-HB thin film electroluminescent (EL) display is a high­performance alternative to quarter-VGA LCDs and is the ideal solution in
demanding applications where superior visual performance and
environmental ruggedness are critical. The EL320.240.36-HB 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 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 EL320.240.36­HB is easily interfaced using standard 4-bit LCD control signals. Each of the
76,800 pixels 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

• Frame Buffer

• Space efficient mechanical package

• Low EMI emissions

• Extremely rugged and durable

• Reliable, long operating life

• 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.

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.

Cable Length

A maximum cable length of 0.6 m (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. Particular
care should be taken when cleaning displays with anti-glare and anti-reflective
films.

Avoiding Burn-In

As with other light emitting displays, use a screen saver or image inversion to
avoid causing burn-in on the display. Displaying fixed patterns on the screen
can cause burn-in, where luminance variations can be noticed.
