DESCRIPTION
The DLR/DLO/DLG3416 is a four character 5x7 dot matrix display module
with a built-in CMOS integrated circuit. This display is a “drop-in” replace-
ment for the DL3416.
• Wide Viewing Angle: X Axis 50° Maximum,
Y Axis ±75° Maximum
• Close Vertical Row Spacing, 0.800" Centers
• Fast Access Time, 110 ns at 25°C
• Full Size Display for Stationary Equipment
• Built-in Memory
The integrated circuit contains memory, ASCII ROM decoder, multiplexing
circuitry and drivers. Data entry is asynchronous and can be random. A dis-
play system can be built using any number of DLX3416s since each charac-
ter can be addressed independently and will continue to display the
character last stored until replaced by another.
• Built-in Character Generator
• Built-in Multiplex and LED Drive Circuitry
• Each Character Independently Accessed
System interconnection is very straightforward. The least significant two
address bits (A0, A1) are normally connected to the like-named inputs of all
displays in the system. With four chip enables, four displays (16 characters)
can easily be interconnected without a decoder.
• TTL Compatible, 5 Volt Power, V =2.0 V,
IH
V =0.8 V
IL
• Independent Cursor Function
• Memory Clear Function
Data lines are connected to all DLX3416s directly and in parallel, as is the
write line (WR). The display will then behave as a write-only memory.
• Display Blank Function for Blinking and Dim-
ming
• End-Stackable, 4-character Package
• Intensity Coded for Display Uniformity
• Extended Operating Temperature Range:
–40°C to +85°C
The cursor function causes all dots of a character position to illuminate at
half brightness. The cursor is not a character, and when removed the previ-
ously displayed character will reappear.
The DLX3416 has several features superior to competitive devices. True
“blanking” allows the designer to dim the display for more flexibility of dis-
play presentation. Finally the CLR clear function will clear the cursor RAM
and the ASCII character RAM simultaneously.
• Wave Solderable
See Appnotes 18, 19, 22, and 23 for additional
information.
The character set consists of 128 special ASCII characters for English, Ger-
man, Italian, Swedish, Danish, and Norwegian.
All products are subjected to out-going AQL’s of 0.25% for brightness match-
ing, visual alignment and dimensions, 0.065% for electrical and functional.

Setting the chip enables (CE1, CE2, CE3, CE4) and
cursor select (CU) to their true state will enable cursor
loading. A write (WR) pulse will now store or remove a
cursor into the digit location addressed by A0, A1, as
defined in data entry. A cursor will be stored if D0=1
and will removed if D0=0. The cursor (CU) pulse width
should not be less than the write (WR) pulse or errone-
ous data may appear in the display.

If the cursor is not required, the cursor enable signal
(CUE) may be tied low to disable the cursor function.
For a flashing cursor, simply pulse CUE. If the cursor
has been loaded to any or all positions in the display,
then CUE will control whether the cursor(s) or the
characters will appear. CUE does not affect the con-
tents of cursor memory.

Display Blanking
The display can be dimmed by pulsing (BL) line at a frequency
sufficiently fast to not interfere with the internal clock. The dim-
ming signal frequency should be 2.5 KHz or higher. Dimming
the display also reduces power consumption.
Blank the display by loading a blank or space into each digit of
the display or by using the (BL) display blank input.
Setting the (BL) input low does not affect the contents of either
data or cursor memory. A flashing display can be achieved by
pulsing (BL). A flashing circuit can be constructed using a 555
a stable multivibrator. Figure 3 illustrates a circuit in which vary-
ing R2 (100K~10K) will have a flash rate of 1 Hz~10 Hz.
An example of a simple dimming circuit using a 556 is illus-
trated in Figure 4. Adjusting potentiometer R3 will dim the dis-
play by changing the blanking pulse duty cycle.

Design Considerations
Chemical, Midland, MI; E.I. DuPont de Nemours & Co., Wilm-
ington, DE.
For details on design and applications of the DLX3416 using
standard bus configurations in multiple display systems, or par-
allel I/O devices, such as the 8255 with an 8080 or memory
mapped addressing on processors such as the 8080, Z80,
6502, or 6800, refer to Appnote 15 in the current Siemens Opto-
electronics Data Book.
For further information refer to Siemens Appnotes 18 and 19.
An alternative to soldering and cleaning the display modules is
to use sockets. Standard pin DIP sockets .600" wide with
0.100" centers work well for single displays. Multiple display
assemblies are best handled by longer SIP sockets or DIP
sockets when available for uniform package alignment. Socket
manufacturers are Aries Electronics, Inc., Frenchtown, NJ;
Garry Manufacturing, New Brunswich, NJ; Robinson-Nugent,
New Albany, IN; and Samtec Electronic Hardware, New Albany,
IN.
Electrical and Mechanical Considerations
Voltage Transient Suppression
We recommend that the same power supply be used for the
display and the components that interface with the display to
avoid logic inputs higher than V . Additionally, the LEDs may
cause transients in the power supply line while they change dis-
play states. The common practice is to place .01 mF capacitors
CC
For further information refer to Siemens Appnote 22.
Optical Considerations
close to the displays across V and GND, one for each dis-
CC
The 0.270" high characters of the DLX3416 gives readability up
to eight feet. Proper filter selection enhances readability over
this distance.
play, and one 10 mF capacitor for every second display.
ESD Protection
Filters enhance the contrast ratio between a lit LED and the
character background intensifying the discrimination of differ-
ent characters. The only limitation is cost. Take into consider-
ation the ambient lighting environment for the best cost/benefit
ratio for filters.
The silicon gate CMOS IC of the DLX3416 is quite resistant to
ESD damage and capable of withstanding discharges greater
than 2 KV. However, take all the standard precautions, normal
for CMOS components. These include properly grounding per-
sonnel, tools, tables, and transport carriers that come in contact
with unshielded parts. If these conditions are not, or cannot be
met, keep the leads of the device shorted together or the parts
in anti-static packaging.
Incandescent (with almost no green) or fluorescent (with almost
no red) lights do not have the flat spectral response of sunlight.
Plastic band-pass filters are an inexpensive and effective way
to strengthen contrast ratios.
Soldering Considerations
The DLR3416 is a standard red display and should be matched
with long wavelength pass filter in the 600 nm to 620 nm range.
The DLO3416 is a high efficiency red display and should be
matched with a long wavelength pass filter in the 470 nm to 590
range. The DLG3416 should be matched with a yellow-green
band-pass filter that peaks at 565 nm. For displays of multiple
colors, neutral density gray filters offer the best compromise.
The DLX3416 can be hand soldered with SN63 solder using a
grounded iron set to 260°C.
Wave soldering is also possible following these conditions: Pre-
heat that does not exceed 93°C on the solder side of the PC
board or a package surface temperature of 85°C. Water soluble
organic acid flux (except carboxylic acid) or resin-based RMA
flux without alcohol can be used.
Additional contrast enhancement is gained by shading the dis-
plays. Plastic band-pass filters with built-in louvers offer the
next step up in contrast improvement. Plastic filters can be
improved further with anti-reflective coatings to reduce glare.
The trade-off is fuzzy characters. Mounting the filters close to
the display reduces this effect. Take care not to overheat the
plastic filter by allowing for proper air flow.
Wave temperature of 245°C ±5°C with a dwell between 1.5 sec.
to 3.0 sec. Exposure to the wave should not exceed tempera-
tures above 260°C for five seconds at 0.063" below the seating
plane. The packages should not be immersed in the wave.
Post Solder Cleaning Procedures
Optimal filter enhancements are gained by using circular polar-
ized, anti-reflective, band-pass filters. Circular polarizing further
enhances contrast by reducing the light that travels through the
filter and relfects back off the display to less than 1%.
The least offensive cleaning solution is hot D.I. water (60°C) for
less than 15 minutes. Addition of mild saponifiers is acceptable.
Do not use commercial dishwasher detergents.
For faster cleaning, solvents may be used. Carefully select any
solvent as some may chemically attack the nylon package.
Maximum exposure should not exceed two minutes at elevated
temperatures. Acceptable solvents are TF (trichorotribluore-
thane), TA, 111 Trichloroethane, and unheated acetone.
Several filter manufacturers supply quality filter materials.
Some of them are: Panelgraphic Corporation, W. Caldwell, NJ;
SGL Homalite, Wilmington, DE; 3M Company, Visual Products
Division, St. Paul, MN; Polaroid Corporation, Polarizer Division,
Cambridge, MA; Marks Polarized Corporation, Deer Park, NY,
Hoya Optics, Inc., Fremont, CA.
Note: Acceptable commercial solvents are: Basic TF, Arklone,
P. Genesolv, D. Genesolv DA, Blaco-Tron TF, Blaco-Tron TA, and
Freon TA.
One last note on mounting filters: recessing displays and bezel
assemblies is an inexpensive way to provide a shading effect in
overhead lighting situations. Several Bezel manufacturers are:
R.M.F. Products, Batavia, IL; Nobex Components, Griffith Plas-
tic Corp., Burlingame, CA; Photo Chemical Products of Califor-
nia, Santa Monica, CA; .E.E.-Atlas, Van Nuys, CA.
