EL480.60.43 Display
The EL480.60.43 thin film electroluminescent (EL) small graphics
display is a low cost, high performance alternative to industry-standard
small graphics LCDs. The EL480.60.43 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
connected using elastomeric interconnects into a space-saving, rugged
package for easy mounting and includes a DC/DC converter. The
EL480.60.43 is easily interfaced using standard 4-bit LCD control
signals. Each of the pixels has an aspect ratio of 1:1 (V:H) and is
individually addressable to clearly display high information content
graphics and text.
Features
♦ Excellent visual performance:
High brightness and contrast
Wide viewing angle > 160°
No compensation needed
♦ Rapid display response < 1 ms
♦ Space-efficient mechanical package
♦ Low EMI emissions
♦ Extremely rugged and durable
♦ Reliable, long operating life with > 50,000 MTBF
♦ 4-bit STN 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 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.
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 (±.025"). Use
all the mounting holes provided. Failure to do so will impair the shock and
vibration resistance of the final installation.
The EL480.60.43 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
EL480.60.43 mounting tabs were designed for a 3 mm screw.
WARNING: These products generate voltages capable of causing
personal injury (high voltage up to 230 VAC ). 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 or anti-reflective films.
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.
Power
The supply voltages are shown in Table 1. All internal high voltages are
generated from the display supply voltage (VH). The logic supply voltage (VL)
should be present whenever video input signals or VH is applied. The minimum
and maximum specifications in this manual should be met, without exception, to
ensure the long-term reliability of the display.
Performance characteristics are guaranteed when measured at 25 °C with rated
input voltage unless otherwise specified. Planar does not recommend operation
of the display outside these specifications.

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.
The standard display has a single connector, 20-pin, 2 mm pitch. The display
uses the Samtec EHT-110-01-S-D-SM locking connector or an equivalent
connector matching the pinouts in Table 3. The mating connector is available
through Samtec as an IDC cable assembly (Series TCSD-10-S-XX.X-). Consult
your Samtec representative (1-800-SAMTEC9) for cable and connector options.

Planar EL Small Graphics Displays (SGD) incorporate an interface that is
similar to many LCD interfaces. This interface is supported by a variety of offthe shelf chip sets which take care of all display control functionality, freeing the
system processor for other tasks. Designers select the chip set that best suits their
particular architecture and price point. This 4-bit LCD-type video interface
provides a low cost, flexible method for controlling display brightness and power
consumption.
Video Input Signals
The end of the top line of a frame is marked by VS, vertical sync signal as shown
in Figure 2. The end of each row of data is marked by HS.
The VS signal may be independently set to a CMOS low level at any time for
longer than one frame period. During the time of VS inactivity the display will
be blank. Halting VS results in a standby condition which minimizes power
consumption.

Figure 3. Pixel Location versus Sequence of Data.
The dimming control circuitry on the display allows the user to adjust the
luminance from 5% to 100% of the maximum brightness.
To control the display luminance, connect a 100 K(ohm) variable logarithmic
potentiometer between ground and the dimming pin. The full resistance of 100
K(ohm) will result in 100% of the maximum luminance. Reducing the resistance
will reduce the luminance, with resistance of 0 K(ohm) yielding roughly 5% of
the maximum luminance.
Alternatively an external voltage or current-mode D/A converter may be used to
dim the display by sinking a maximum of 250 uA for maximum dimming from

pin 4 to ground. When left open, the luminance will remain at the maximum
off
level.
Self-Test Mode
The display incorporates a self-test mode composed of a 1 x 2 checkerboard and
full-on pattern displayed at 360 Hz. Upon power up, the 1 x 2 pattern is
displayed for several seconds, then the full-on pattern is displayed continuously.
The self-test mode is entered by leaving the SELFTEST pin pulled high. For
normal operation the SELFTEST pin must be pulled to a logic low. If the
SELFTEST pin is pulled high during normal operation, the display will enter the
self-test mode.

advises users to design enclosure components to be outside the component
envelope.
An air gap of at least 5 mm is recommended to dissipate heat from display
components. Device designers will need to consider their specific system
requirements to determine the necessary spacing.
