Electrical and Mechanical Considerations
Voltage Transient Suppression
For best results power the display and the components that inter-
face with the display to avoid logic inputs higher than V
CC. Addi-
tionally, the LEDs may cause transients in the power supply line
while they change display states. The common practice is to place
a parallel combination of a 0.01 F and a 22 F capacitor between
V
CC and GND for all display packages.
ESD Protection
The input protection structure of the IPD2131X provides significant
protection against ESD damage. It is capable of withstanding dis-
charges greater than 4.0 kV. Take all the standard precautions nor-
mal for CMOS components. These include properly grounding
personnel, tools, tables, and transport carriers that come in con-
tact 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 IPD213X can be hand soldered with SN63 solder using a
grounded iron set to 260°C.
Wave soldering is also possible. Use water soluble organic acid
flux or resin based RMA flux.
A wave temperature of 245°C ±5°C with a dwell between 1.5 sec.
to 3.0 sec. can be used. Exposure to the wave should not exceed
temperatures above 260°C for five seconds at 1.59 mm (0.063")
below the seating plane. The packages should not be immersed in
the wave.
Post Solder Cleaning Procedures
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. Suggested solvents
include Genesolv DE-15, Genesolv DI-15, and Genesolv DES.
An alternative to soldering and cleaning the display modules is to
use sockets. 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 Brunswick, NJ;
Robinson-Nugent, New Albany, IN; and Samtec Electronic Hard-
ward, New Albany, IN.

Optical Considerations
The 4.85 mm (0.200") high character of the IPD213X gives read-
ability up to eight feet. Proper filter selection enhances readability
over this distance.
Using filters emphasizes the contrast ratio between a lit LED and
the character background. This will increase the discrimination of
different characters. The only limitation is cost. Take into consider-
ation the ambient lighting environment for the best cost/benefit
ratio for filters.
Incandescent (with almost no green) or fluorescent (with almost no
red) lights do not have the flat spectral response of sunlight. Plas-
tic band-pass filters are an inexpensive and effective way to
strengthen contrast ratios. The high efficiency red displays should
be matched with a long wavelength pass filter in the 570 nm to
590 nm range. The IPD2133 should be matched with a yel-
low-green band-pass filter that peaks at 565 nm. For displays of
multiple colors, neutral density grey filters offer the best compro-
mise.
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.
Optimal filter enhancements are gained by using circular polarized,
anti-reflective, band-pass filters. The circular polarizing further
enhances contrast by reducing the light that travels through the filter
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 Polarized 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 Products of California,
Santa Monica, CA; I.E.E.-Atlas, Van Nuys, CA.
RoHS Compliance
The IPD2132, IPD2131, IPD2133 Intelligent Displays
TM are her-
metically sealed displays using a ceramic and glass construction.
These components are not lead (Pb) free but are RoHS Compliant
based on the RoHS Compliance Directive's Annex, paragraphs 5
and 7. These exemptions allow for lead (Pb) in glass and ceramic
electronic components. Refer to the following excerpts from the
RoHS Compliance Directive Annex:
Applications of lead, mercury, cadmium and hexavalent chromium,
which are exempted from the requirements of Article 4(1)
5. Lead in glass of cathode ray tubes, electronic components and
fluorescent tubes.
7. Lead in electronic ceramic parts (e.g. piezoelectronic devices).
