Options
Anti-glare and conformal coating options are available on this display.
The anti-glare option adds an anti-glare film to the front of the display to
reduce specular reflections (see Application Note 135 for more information).
The conformal coating option adds a protective layer to the display for
applications in which the display may be subjected to high humidity, dust, or
salt mist (see Application Note 122 for more information).
Installation and Handling
The mechanical package consists of the display panel and electronic circuit
board bonded together, plus a protective cover carrying the display mounting
ears. The display is made of glass material and must be handled with care.
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.
Do not drop, bend, or flex the display. Do not allow objects to strike the
surface of the display.
Mounting EL Displays
The EL640.480 AM displays were designed to facilitate the mounting of optical
treatments and touchscreens on the viewing side of the display. To this end,
the glass extends in front of the mounting bezel by approximately 0.5 mm
(0.02 in.). It is imperative that any mounting scheme apply uniform pressure at
all times across the glass. Pressure applied to the corners or edge of the glass is
likely to cause breakage.
Mounting should be done using the mounting ears only. Use either metric M3
screws torqued to 350 Ncm maximum, or unified #4 screws torqued to 4.7
in/lb maximum.
CAUTION: Properly mounted, this display can withstand high shock loads
and severe vibration in aggressive environments. However, the glass panel
used in this display will break when subjected to bending stresses, high
impact, or excessive loads.
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 200 Vac ). Do not touch the display electronics
during operation.

EL640.480-AM Operations Manual (020-0351-00C) 5
Cable Length
The maximum recommended cable length is 600 mm (24 in.). Longer cables
may cause data transfer problems between the data transmitted and the
display input connector. Excessive cable lengths can pick up and source
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.
The TAB (tape-automated bonding) leads between the electronics and the
display glass are very sensitive to handling. When cleaning the edges of the
display glass, special care should be taken not to damage the leads.
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.

Specifications
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. Operating voltages required
are provided by a DC/DC converter.
Unless otherwise specified, performance characteristics are guaranteed when
measured at 25°C.
Power
The supply voltages required for the displays are shown in Table 1. All internal
high voltages are generated from display supply voltage (VH). The logic supply
voltage (VL) should be present whenever video input signals or VHis applied.

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

EL640.480-AM Operations Manual (020-0351-00C) 7
Input Voltage Selection
The AM8 displays (except AM8 ETL) feature a jumper
that allows the user to choose between 12 and 24 volt
supply voltage. The displays are shipped with the JP1
jumper in the pin 1/pin 2 position which sets the
supply voltage at 12 volts.
To select a 24 volt supply, move the JP1 jumper to the
pin2/pin3 position. Pin one is marked on the +12 V
end of JP1.
CAUTION: Providing a 24 volt supply to the display when the jumper is in the
12 volt supply position will damage the display.
The display will not function if the jumper is removed completely. Planar
recommends the use of a non-conductive adhesive to secure the jumper in
the desired position in environments where shock or vibration might loosen
the jumper.
The minimum and maximum specifications in the 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.
Connectors
AM1 Data and Power Connector
The AM1 displays use the Samtec STMM-110-01-S-D or equivalent connector,
and the AM8-IN displays use the Samtec STMM-110-01-T-D or equivalent
connector. The mating connector for both the AM1 and AM8-IN displays is in
the Samtec TCSD family of cable strips. The proper connector, user-specified
cable length, and connector configuration are supplied as a single unit.

Locking Power and Data Connector
The AM8 IN display may be ordered with an optional 20
pin, 2 mm through-hole locking male header, Samtec
EHT-110-01-S-D or equivalent. The locking connector
is standard on the AM8 ET and AM8 ETL. The locking
connector adds 2.0 mm to the display depth.
The Samtec mating connector for the non-locking
power and data connector on the AM1 and AM8 IN
will mate with the locking connector. Compatibility
with non-Samtec equivalents should be verified
before use.
Dimming Connector J2
An analog dimming circuit is standard on the AM8. The
J2 dimming connector is a Molex 2-pin, right angle
locking male, part number 22-12-2024. The
recommended mating connector is a Molex 22-01-3027
(housing) and 08-52-0123 (crimps, 2 per housing).
Additionally the crimp housing will need crimp terminals
to connect the wires, Molex 2759 or 6459 can be used.
Molex crimp terminal 41527 is recommended for applications with high
vibration requirements.
For a discussion of the dimming feature, refer to the Dimming section below,
under Optical Performance.
Interfacing
This dual scan LCD-type video interface provides a low cost, flexible method
for controlling display brightness and power consumption. Many off-the-shelf
chipsets are available for interfacing to flat panel displays. If your application
does not require chip-level integration, there are many vendors that can
supply board-level solutions for serial control, PC104, ISA, and many other
interfaces.
Planar Application Note 116 summarizes some of the interfacing options that
have been used in the past with EL VGA displays.

Input signals UD0 through UD3 contain the video data for the upper screen
and signals LD0 through LD3 contain the data for the lower screen. For
example, four pixels (UD3:1,1–UD0:1,1) are sent to row 1 at the same time as
four pixels (LD0:1,1–LD3:1,1) are sent to row 241. This results in eight pixels
sent on each cycle of video clock CP2. Pixel information is supplied from left to
right and from top to bottom. Video data for one row is latched on the fall of
CP1 (Figure 5).

Self-Test Mode
The display incorporates a self-test mode composed of a 1x2 checkerboard
pattern that inverts every few seconds. The self-test mode is entered by
applying power to the display with the Ssignal static. The display remains in
this mode until two (2) low-to-high transitions of the Ssignal are detected. The
display then enters and remains in normal (user video driven) operation as
long as power is applied. To enter self-test mode again, the display must be
reset by cycling the VHpower input.

Dimming
There are two standard methods for dimming the AM displays. Frame rate
dimming allows the brightness of the display to be lowered proportionally by
reducing the frame rate. Analog dimming allows the brightness to be reduced
with an external, user supplied potentiometer or electronic circuitry. The
brightness range for analog dimming is from 100% to nearly 5% of the full
brightness.
Frame rate dimming is performed within the application by lowering the
frame rate of the video input signals. Because brightness is proportional to
refresh rate, the display can be dimmed by adding pauses between every
horizontal period.
The lowest possible frame rate (brightness) is dependent on the perceived
flicker of the displayed image, but will most likely be around 60 Hz. For more
information on frame rate dimming please see Planar Application Note 120.
The analog dimming feature utilizes a 50k ohm logarithmic external
potentiometer, allowing manual control of the display’s brightness. Analog
dimming is standard on the AM8 IN and AM8 ET displays. The typical current
for minimum brightness is 220 µA.

EL640.480-AM Operations Manual (020-0351-00C)
14
Grayscale
Using the display’s higher frame rate frequency, combined with flat panel
controllers, it is possible to generate a wider range of usable grayscales
through frame rate control and dithering.
Frame Rate Control generates true grayscales by turning pixels on and off over
several frames of time. The user’s eye sees each individual pixel as gray. The
potential problems with this method are brightness-profile and shadowing,
especially when used to shade larger areas.
Dithering generates grayscales by patterning the area to be shaded. The
tested C&T controllers use a pattern of 4 (2x2) pixels to generate the dithered
grayscales. When the area is viewed from a distance, it appears to the user’s
eye as gray. When viewed up close, the different brightness of the individual
pixels can be observed.
Many of the grayscales that can be generated may flicker or swim. Through
careful selection however, several grayscale patterns are available for most
applications, particularly when the display is driven at its maximum frame rate
frequency. Planar Application Note 119 is available for more information on
generating grayscale images.
Reliability
The MTBF (mean time between failures) is a minimum of 50,000 hours at 25°C
ambient, except for performance characteristics with an otherwise specified
life expectancy.
