1EL160.80.50-ET SPI display
The EL160.80.50-ET SPI thin film electroluminescent (TFEL) display is a low cost, high
performance alternative to small LCDs, LEDs or VFDs. The EL160.80.50-ET SPI utilizes
Lumineq®Displays’ proprietary Integral Contrast Enhancement (ICEBrite™) 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 a TFEL glass panel and control electronics assembled into a space-
saving, rugged package for easy mounting. The EL160.80.50-ET SPI is easily interfaced using
the Serial Peripheral Interface (SPI) bus. Each of the 12,800 pixels is individually addressable
to clearly display high information content graphics and text. The display is equivalent to a 10
x 26-character display in text mode (assuming 5 x 7 characters).
1.1 Features and benefits
•Excellent visual performance:
▪High brightness and contrast
▪Wide viewing angle > 179°
•Rapid display response < 1 ms
•Space efficient mechanical package
•Low EMI emissions
•Extremely rugged and durable
•Reliable, long operating life
•SPI interface
2Installation 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.
2.1 Mounting
Properly mounted, TFEL displays can withstand high shock loads as well as severe vibration
found in demanding applications. However, the glass panel used in a TFEL 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. Mounting surfaces

should be flat to within ±0.6 mm (±0.25"). Use all the mounting holes provided; failure to do
so will impair the shock and vibration resistance of the final installation.
The EL160.80.50-ET SPI 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 circuit board out of its normal plane.
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 230 VAC). Do not touch the display electronics during operation.
2.2 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.
2.3 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, and 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.
Care should be taken when cleaning displays with anti-glare and anti-reflective films.
2.4 Avoiding burn-in
As with other light emitting displays, displaying fixed patterns on the screen for extended
periods of time can cause burn-in, where luminance variations can be noticed. Use a
screensaver or image inversion to avoid causing burn-in on the display.
3Specifications
Performance characteristics are guaranteed when measured at 25 °C with rated input voltage
unless otherwise specified.
3.1 Control basics
The TFEL 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.

3.2 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 VHis applied. The minimum and maximum specifications in this manual
should be met, without exception, to ensure the long-term reliability of the display. Beneq
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. Beneq 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.

3.3 Connectors
3.3.1 Standard data and power connector
The 160.80.50-ET SPI displays use the Samtec locking connector EHT-110-01-T-D or
equivalent connector. The suitable mating connector can be found from the Samtec TCSD
family of cable strips. For proper mating connector/cable options consult your Samtec
representative. Compatibility with non-Samtec equivalents should be verified before use.

3.3.2 Dimming connector J2
The dimming connector is a Leoco part number 2011P02V000, which is a 2-pin, 2 mm,
header. The recommended mate is a Leoco part number 2010S020000 (housing) with Leoco
part number 2O33TPB0000 (contact).
For more information on the dimming feature, refer to the 3.8 Dimming.
3.4 Interface information
Beneq EL160.80.50-ET SPI Small Graphics Display (SGD) incorporates a SPI interface that is
like many LCD modules. This SPI video interface provides a low-cost, flexible method for
controlling display brightness and power consumption. Designers should select the chip set or
embedded board that best suits their architecture.
3.4.1 Video input signals
The SPI is driven with the rising edge of SCLK. A falling edge on SS signal indicates the
beginning of an access on the SPI, the rising edge of SS signal ends an access on SPI. An
access must consist of exactly 8 bits or multiple of 8 bits for a write operation. A longer
command can be split to several SPI accesses if needed. The SPI interface Clock polarity
(CPOL) and clock phase (CPHA) are 0. At CPOL=0 the base value of the clock is zero for
CPHA=0 and data are captured on the clock's rising edge (low to high transition) and data is
propagated on a falling edge (high to low clock transition).
