EL240.128.45 Display
The EL240.128.45 thin film electroluminescent (EL) small graphics
display 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 EL240.128.45 is easily interfaced using a built-in
RAiO RA8835A standard LCD controller. 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 and Benefits
•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
•Low power (3 W)
•Reliable, long operating life with >100,000 MTBF
•Built-in RAiO RA8835A standard LCD controller
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.
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 EL240.128.45 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 EL240.128.45 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.
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, 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.

EL240.128.45 Operations Manual (020-0345-00C) 5
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 are 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.

Interface Information
This Small Graphics Display (SGD) incorporates an interface that is
compatible with the 8-bit microprocessor interfaces found in comparable
LCD displays with built-in controllers. The display incorporates a built-in
RAiO RA8835A standard LCD controller.
Table 4. Pin Settings.
Signal Functional Description
D0 to D7 Pins 13-20: Tristate input/output pins. Connect to an 8- or 16-bit µP-bus.
SEL1 Pin 21: µP-interface select. Both 8080-family and 6800-family processors are
supported. SEL1 should be tied directly to VL or GND to prevent noise.
SEL1 Interface A0 /RD /WR /CS
0 8080 family A0 /RD /WR /CS
1 6800 family A0 E R//W /CS
/RD or E Pin 8: With the 8080 interface, this signal acts as the active-LOW read strobe.
With the 6800 interface, this signal acts as the active-HIGH enable clock. Data
is read from or written to the display when this clock goes HIGH.
/WR or
R//W
Pin 7: With the 8080 interface, this signal acts as the active-LOW write strobe.
The bus data is latched on the rising edge of this signal. With the 6800
interface, this signal acts as the read/write control signal. Data is read from the
display if this signal is HIGH, and written to the display if it is LOW.
/RES Pin 6: When low resets RA8835A, must be high or unconnected in normal
operation
READY Pin 22: OUTPUT When data for Row 128 is written to display drivers this
signal goes high. While the signal is high it is possible to write data to
RA8835A memory so that it does not cause disturbances to display data. This
signal goes low at latest 3.5 µs before when loading of Row 1 data begins.
Signal READY output is CMOS with 100 Ωseries resistor.
/CS Pin 9: Chip select. This active-LOW input enables the RA8835A. It is usually
connected to the output of an address decoder device that maps the RA8835A
into the memory space of the controlling microprocessor.

Dimming
The dimming control circuitry on the display allows the user to adjust the
luminance from 5 % to 95 % of the maximum brightness.
To control the display luminance, connect a 50 kΩvariable resistor
between ground and the dimming pin (LUMA). The full resistance of 50
kΩwill result in 95 % of the maximum luminance. Reducing the
resistance will reduce the luminance, with resistance of 0 Ωyielding
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 µA for maximum
dimming from LUMA to ground. When left open, the luminance will remain
at the maximum level.
Table 7. Luminance Control.
Maximum (No resistor connected): 100 % (Default)
Maximum (50 k Ωresistor connected): 95 %
Minimum (0 Ω resistor connected): 5 % maximum
Open Circuit voltage 4 V nominal
Sink Current 250 µA max, Vin = 0 V
Luminance values are measured as a percentage of full On Luminance
(with the external resistor disconnected.)
Self-Test Mode
The display incorporates a self-test mode composed of a 1 x 1
checkerboard and full-on pattern displayed at 240 Hz. Upon power up,
the 1 x 1 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 with the all-pixels-on
pattern.
Power-up Sequence
No special power-up or video sequencing is required.

necessarily fill this area. Planar reserves the right to relocate components
within the constraints of the component envelope without prior customer
notification. For this reason, Planar 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.
