DESCRIPTION
The SLR/SLO/SLG/SLY2016 is a four digit 5 x 7 dot
matrix display module with a built-in CMOS integrated
circuit. This display is X/Y stackab le.
The integrated circuit contains memory, a
128 ASCII ROM decoder, multiplexing circuitry and driv-
ers. Data entry is asynchronous. A display syste m can be
built using any number of SLR/SLO/SLG/SLY2016 since
each digit can be addressed independently and will con-
tinue to di spla y the ch aracter last stored unt il replaced b y
another.
System interconnection is very straightforward. Two
address bits (A0, A1) are normally connected to the
like-named inputs of all displa ys in the system.
Data lines are connected to all SLR/SL O/SLG/SLY2016s
directly and in parallel as is the write line (WR). The dis-
play will then behave as a write-only memory.
The SLR/SLO/SLG/SLY2016 has several features supe-
rior to competitive devices. 100% burn-in processing
insures that the SLR/SLO/ SLG/SLY2016 will function in
more stressful assembly and use environment s. True
“blanking” al lows the desi gner to dim the displa y f or more
flexibility of display presentation. Finally the CLR cl ear
function will clear the ASCII character RAM.
The character set consists of 128 special ASCII charac-
ters for English, German, Italian, Swedish, Dani sh, and
Norwegian.
All products are 100% burned-in and tested, then
subjected to out-going AQL’s of 0.25% for brightness
matching, visual alignment and dimensions, 0.065% for
electrical and functional.

Loading Data
The desired data code (D0–D6) and digit address (A0, A1) must
be held stable during the write cycle for storing new data.
Data entry may be asynchronous. Digit 0 is defined as right hand
digit with A1=A2=0.
Clearing the en tire internal f our-di git memory can be acco mplished
by holding the clear (CLR) low for 1.0 msec minimum. The clear
function will clear the ASCII RAM. Loading an illegal data code will
display a blank.

Display Blanking
Blank the display by loading a blank or space into each digit o f th e
display or by using the (BL) display blank input. Setting the (BL)
input low does not affect the contents of data memory.
A flashing circuit can easily be constructed using a 555 as table
multivibrator. Figure 3 illustrates a circuit in which varying R1
(100K~10K) will have a flash rate of 1.0 Hz~10 Hz.
The display can be dimmed by pulse width modulating the (BL) at
a frequency sufficiently fast to not interfere with the internal clock.
The dimming signal frequency should be 2.5 kHz or higher. Dim-
ming the display also reduces power consumption.
An example of a simple dimming circuit using a 556 is illustrated in
Figure 4. Adju sting pote ntiome ter R3 will d im the disp lay by chang-
ing the blanking pulse duty cycle.

Design Considerations
For details on design and applications of the SLX2016 in multiple
display systems, refer to Appnote 15 at www.osram-os.com
Electrical & Mechanical Considerations
Voltage Transient Suppression
We recommend that the same power supply be used for the dis-
play and the components that interface with the display to avoid
logic inputs highe r than VCC. Additionally, the LEDs may cause
transients in the power supply line while th ey chan ge display
states. The common practice is to place 0.01 mF capacitors close
to the displa ys across VCC and GN D, one f or each displa y, and one
10 µF capacitor for every second display.
ESD Protection
The CMOS IC of the SLX2016 is resistant to ESD damage and
capable of withstanding discharges less t han 2.0 kV. However,
take all the standard precautions, normal for CMOS components.
These include properly grounding personnel, 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.
Soldering Considerations
The SLX2016 can be hand soldered using a grounded iron set to
260°C.
The display is compatible with leadfree and tin/lead solder. Wave
soldering is also possible following these conditions. Preheat does
not exceed 93°C on the solder side of the PC board or a package
surfa ce tem pe rature of 85°C . Water soluble organic acid flux (ex-
cept carboxylic acid) or resin-based RMA flux without alcohol can
be used.
Wa ve temp erature of 245°C +/- 5°C with a dwell betw een 1.5 sec. to
3 sec. Exp osure to the wave should not exceed temperatures
above 260°C for five seconds at 0.063 inches below the seating
plane. The pa ckages should not be immersed in the wave.
Po st Solder Cl eaning Procedures
The least offensive cleaning solution is hot D.I. water (60 °C) for
less than 15 min utes. Add ition of mild saponifiers is acceptable. Do
not use commercial dishwasher detergen ts.
For f aster cleaning , solv ents ma y be used. Carefully select an y sol-
vent as some may chemically attack the n ylon pa c kag e . Maximum
exposure should not exceed two minutes at elevated tempera-
tures. Acceptable solvents are TF (trichorotrifluorethane), TA, 111
Trichloroethane, and unheated acetone.
Note:
Acceptable commercial solvents are: Basic TF, Arklone,
P. Genesolv, D. Genesolv DA, Blaco-Tron TF and
Blaco-Tron TA.
Unacceptab le solvents contain alcohol, meth anol, m ethylene chlo-
ride, ethanol, TP35, TC M, TMC, TM S+, TE, or TES. Si nce many com-
mercial mixtures exist, contact a solv en t v en dor for chemical
composition information. Some major solvent manufacturers are:
Allied Chemical Corporation, Specialty Chemical Division, Morris-
town, NJ; Baro n-Bl ak esl ee , Ch ic ago, IL; Dow Chem ical , Midl and, MI;
E.I. DuP ont de Nemours & Co., Wilmington, DE.
For further information refer to Appnotes 18 and 19 at
www.osram-os.com
An alternative to soldering a nd cleaning the disp lay modules is to
use sockets. Standard pin DIP sockets 7.62 mm (0.300") wide with
2.54 mm (0.100") centers work well for single displays. Multiple
display assemblies ar e be st han dled by longer SIP sockets or DIP
sockets when available for uniform package alignment. Socket
manufacturers are A ries Electronics, Inc., Frenchtown, NJ; Garry
Manufacturing, New Brunswick, NJ; Robinson-Nugent, New
Albany, IN; and Samtec Electronic Hardware, New Albany, IN.

Optical Considerations
The 4.72 mm (0.180") high characters of the SLX2016 gives
readability up to eight feet. Proper filter selection e nhances re ad-
ability over this distance.
Filters enhance the contrast ratio between a lit LED and the character
backg round in tensifyi ng the d iscriminati on of different characte rs.The
only limitatio n is cost. Take in to cons iderat ion t he ambie nt lighti ng en vi-
ronment f or the best cost/b enefit r atio f o r filter s.
Incandescent (wit h almost no g reen) or fluorescent (w ith almost no
red) lights do not have the flat spectral response of sunlight. Plas-
tic band-pass filter s are an in expensive and effective way to
strengthen contrast ratios.The SLR2016 is a standard red display
and should be matched with long wavelength pass filter in the
600 nm to 620 nm range.
The SLO2016 is a super-red display and should be matched with a
long wav elength pass filter in the 470 nm to 590 nm range. Th e
SLG/SLY2016 should be matched with a yellow-green band-pass fil-
ter that peaks at 565 nm. For displays of multiple colors, neutral den -
sity gray filters off er the best compromise.
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-refle ctive coatings to re duce glare . The trad e-off is
fuzzy characters. Mounting the filters close to the display reduces
this effect. Take care no t to overheat the plastic filter by allowing f or
proper air flow.
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 fil-
ter and reflects back off the display to less than 1%.
Several filter manufacturers supply quality filter materials. Some of
them are: Panelgraphic Corporation, W. Caldwell, NJ; SGL Homa-
lite, Wilmington, DE; 3M Company, Visual Products Division, St.
Paul, MN; Polaroid Corporation, Polarizer Division, Cambridge,
MA; Marks Po larized Corporation, Deer Park, NY, Hoya Optics,
Inc., Fremont, CA.
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 Plastic
Corp., Burlingame, CA; Photo Chemical Prod ucts of Califor nia,
Santa Monica, CA; I.E.E.-Atlas, Van Nuys, CA.
