1ELT160.60.100-07NC display
The ELT160.60.100-07NC from Lumineq®Displays is a transparent thin film
electroluminescent TASEL® display without cover glass (=NC) for transparent TFEL
technology with a substrate thickness of 0.7 mm. The display is primarily for in-glass
laminated applications.
The display consists of a TFEL glass panel and control electronics that are connected to TFEL
glass with a flexible flat cable (aka. flexible printed circuit, FPC).
The display has 160 x 60 = 9,600 pixels. Each of the 9,600 pixels is individually addressable
to clearly display high information content graphics and text. The display is equivalent to a 7
(rows) x 26 (columns) character display in text mode (assuming 5 (pixel width) x 7 (pixel
height) characters with one pixel separation in row and col direction).
Product name: ELT160.60.100-07NC
Product number: EL00045100
Document number: ED001129C

•Very good photopic transparency
•Rapid display response < 1 ms
•SPI (“serial peripheral interface”) interface, protocol FPGA programmable at display
controller electronics
•Dimming capability (for the whole display area, not for separate pixels)
•Dark Row Skipping feature enabling increased brightness
•MTBF: when properly laminated, 50,000 h based on historical references
1.2 Parts included
The display consists of a
•Transparent TFEL (TASEL) glass panel
•Control electronics connected to TFEL glass (PCB)
•Flexible flat cable(s) (flexible printed circuit, FPC) connecting the control electronics
and display panel (connector at control electronics end, fixed to the glass panel end).
There are four FPCs in the display, two for segment electrodes and two for row
electrodes.
1.3 Note
All TBD items are to be specified later by Beneq Oy.

2Installation and handling
Do not drop, bend, or flex the display. Do not allow objects to touch the surface of the
display without cover glass. Additional handling instructions will be provided separately.
CAUTION: The display uses CMOS and power MOS-FET devices. These
components are electrostatic sensitive. Unpack, assemble, and examine this
assembly in an ESD controlled area only.
2.1 Mounting
Properly laminated into a larger glass and 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; improper mounting could cause the glass to break.
Avoid causing stress to the display flex cable connection. Extensive stress to the cable
connection could damage the cable connection.
Avoid bending sharp edges to the display flex cable as this could break the FPC internally.
The display comes with no cover glass. This makes the top side (electrode side) of the glass
very sensitive to any touch. Touch the display only by the sides and avoid any sharp contact
to the top surface.
WARNING: These products generate voltages capable of causing personal injury (high
voltage up to 235 Vac). Do not touch the display electronics during operation.
2.2 Cleaning
As the display is delivered with no encapsulation (cover glass) and delivered clean, there
should be no need for cleaning the display panel. Virtually any abrasive or wet wiping of the
display area from the electrode side will damage the display.
Dust particles may be blown away with ionized dry air.
Installation in clean room environment is recommended.

2.3 Interface cable length
A maximum cable length of 600mm (24 in.) is recommended between the customer’s
electronics and display electronics. Longer cables may cause data transfer problems between
the data transmitted and the display input connector. Excessive cable lengths can pick up
unwanted EMI.
2.4 Glass Handling
For important safety information and tips in handling of the display glass, please consult
www.beneq.com/glasshandling.
2.5 Avoiding latent image
As with all light emitting displays, displaying fixed patterns on the screen for extended
periods of time can cause so-called latent image (aka. burn-in), where permanent luminance
variations can be noticed in the display. If possible, turn the screen off from time to time, or
use a screen saver or image inversion to avoid this.

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(row)-at-a-time
data addressing scheme.
The display has no grayscale capability, but does have a dimming (overall brightness control)
capability.
3.2 Power
The power consumption of the display (and display electronics) will depend on the overall
brightness target. Estimated typical power consumption of the display device is 20 W.
The supply voltages are shown in Table 1. All internal high voltages are generated from the
display supply voltage (VH). 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.
Any combination or sequencing in the application or removal of VL, VH, or video signals will
not result in abnormal display operation or display catastrophic failure.

3.4 Interface information and Protocol
Beneq EL160.60.100-07NC display incorporates an SPI interface that is similar to 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 particular 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 for write operation.
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).
The timing restrictions on SPI are defined in figure 2 and table 4:

3.6 Self-test mode
The display incorporates a self-test mode composed of two patterns displayed for
approximately one minute each, and then repeated. The patterns are as follows: Full On and
1 x 1 Checkerboard.
The self-test mode is started at power-on until the first command to the display is detected.
For no self-test at display startup, the SELFTEST pin must be connected to ground.
3.7 Material
Display material is soda lime glass with thin films of the display (DSD stack) and its electrical
structure (ITO traces). ITO thickness is 600 nm.
3.8 Optical
The Display emits a yellow light with peak emission at approximately 582 nm. The luminance

3.9 Dimming
Dimming of the display is handled through the communications protocol of the display
(“digital dimming”), or through the LUMA pin (pin #10; analog dimming).
Analog dimming allows for manually adjustable dimming from 100% to approximately 5% of
the full brightness. To perform analog dimming, connect a 50 kΩ variable resistor between
LUMA and GND. Alternatively, an external voltage or current mode D/A converter may be
used to facilitate dimming by sinking a maximum of 250 μA (for maximum dimming) from
LUMA to GND on the input connector. Open circuit voltage of the LUMA pin is 4 V nominal.
