EL640.200-SK Half-VGA Display
The EL640.200-SK thin film electroluminescent (EL) display is a high-
performance alternative to industry-standard LCDs and is the ideal solution in
demanding applications where superior visual performance and
environmental ruggedness are critical. The EL640.200-SK utilizes Planar’s
proprietary Integral Contrast Enhancement (ICE) technology to achieve
unparalleled image quality without the use of expensive filters. This 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 EL640.200-SK is easily interfaced using standard 4-bit or 8-bit LCD control
signals. Each pixel 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 provides compatibility with low-cost LCD video
controllers
• Space efficient mechanical package
• Low power
• Low EMI emissions
• Extremely rugged and durable
• Reliable, long operating life
• 4-bit buffered and 8-bit non-buffered dual-panel LCD-type interfaces

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 MOSFET 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
EL640.200-SK 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 V
ac
). 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. 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 over time.

Specifications
Performance characteristics are guaranteed when measured at 25°C with rated
input voltage unless otherwise specified. The minimum and maximum
specifications in this manual should be met, without exception, to ensure the
long-term reliability of the display. Planar does not recommend operation of
the display outside these specifications.
Control Basics
The EL panel is a matrix structure with column and row electrodes arranged in
an X-Y formation. Light is emitted when an AC voltage of sufficient amplitude
is applied at a row-column intersection. The display operation is based on the
symmetric, line-at-a-time data addressing scheme.
Power
The supply voltages are shown in Table 1. All internal high voltages are
generated from the display supply voltage (VH).

There is no overcurrent protection on either the VH or VL inputs to protect
against catastrophic faults. Planar recommends the use of a series fuse on the
12-volt supply (VH). A general guideline is to rate the fuse at 1.8 to 2 times the
display maximum current rating.

Connector
Video signals and DC power are connected to the display through a 24-contact
dual-row 2 mm square pin locking connector, Samtec EHT-112-01-S-D. The
mating connector is available through Samtec as an IDC cable assembly (Series
TCSD-12-S-XX-01-X-X). The proper connector, user-specified cable length, and
connector configuration are supplied as a single unit. Consult your Samtec
representative (1-800-SAMTEC9) for cable and connector options.
