EL640.480-AG1 Series VGA Display
The EL640.480-AG1 series displays are 8.1" diagonal VGA products which offer
designers an affordable solution in demanding applications where superior visual
performance and environmental ruggedness are critical. Utilizing Planar’s
proprietary ICEBrite (Integrated Contrast and Brightness Enhancement)
technology, these displays excel in ambient light environments ranging from
dark to nearly sunlight-bright. This technology achieves very high contrast and
exceptionally clear images using a common 8-bit FPD-type interface compatible
with most LCD video controller chips.
The EL640.480-AG1 ET (AG ET) is the extended-temperature version of the
EL640.480-AG1 (AG) display. See temperature specifications on page 14 for more
information. The EL640.480-AG1 ET LP (AG ET LP) is the low-profile version of the
AG1 ET.
Through simple design and advanced manufacturing technologies, Planar’s new
VGA display family brings the visual performance and image quality of EL into
cost-sensitive applications that have up to now been limited by the performance
of LCD displays.
Features and Benefits
• Excellent visual performance:
High brightness and contrast
Wide viewing angle >160°
• Reliable, long operating life
• Extremely rugged and durable
• Low EMI emissions
• Rapid display response <1 ms
• Low power design
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).
A locking connector, which is standard in the AG ET version, is optional with the
AG display.

Installation and Handling
The mechanical package consists of the display panel and electronic circuit board
adhesively bonded together and mounted in a plastic bezel. The bezel supplies
the mounting ears and protects otherwise exposed leads. The display is made of
glass material and must be handled with care.
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.
Do not drop, bend or flex the display. Do not allow objects to strike the surface of
the display.
Mounting EL Displays
The AG1 display series was designed to facilitate the mounting of optical
treatments and touch screens 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") It is
imperative that any mounting scheme apply uniform pressure across the glass at
all times. Pressure applied only 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 tightened to 350 Ncm maximum, or unified #4 screws tightened to 4.7
in/lb maximum.
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.
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 230 V
ac
). Do not touch the display electronics during operation.

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

Specifications
Performance characteristics are guaranteed when measured at 25°C with rated
input voltage unless otherwise specified.
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. Required operating voltages
are provided by an integrated DC/DC converter.
Power
The supply voltages required for the displays are shown in Table 1. All internal
high voltages are generated from display supply voltage (V
H
). The logic supply
voltage (V
L
) should be present whenever video input signals or V
H
is applied. 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.

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.

Data and Power Connector
The EL640.480-AG1 display uses the Samtec STMM-110-01-T-D and the
EL640.480-AG1 ET display uses the Samtec EHT-110-01-S-D or equivalent locking
connectors. Although these connectors differ slightly, their pinouts are identical
and are shown in the table below. The mating connector for both 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. A low-
profile version display, the EL640.480-AG1 LP, uses the EHT110-01-S-D-RA right-
angle connector. Consult your Samtec representative (1-800-SAMTEC9) for the
cable/connector options.

Locking Power and Data Connector
The display may be ordered with an optional 20
pin, 2 mm through-hole locking male header,
Samtec EHT-110-01-S-D or equivalent. This
locking connector is standard on the
EL640.480-AG1 ET display. The mating
connector is in the Samtec TCSD family of cable
strips. Compatibility with
non-Samtec equivalents should be verified
before use.
Dimming Connector J2
The ET version of this display includes a J2 analog
dimming circuit which is not available on the
standard display. The J2 dimming connector is a 6-
pin, straight-locking header made by FCI, part
number 98424-G52-06A. The recommended mating
connector is an FCI 89947-306 (IDC) or FCI 77138-001
and 90311-006 (crimp-to-wire receptacle plus
housing) or equivalent.
