The HDSP-553x/-3900 and
HDSP-4030/-4130/-5730/-4200
are 7.6 mm, 10.9 mm/14.2 mm/
20.3 mm high efficiency red and
yellow displays designed for use
in high light ambient condition.
The four sizes of displays allow
for viewing distances at 3, 6, 7,
and 10 meters. These seven
segment displays utilize large
junction high efficiency LED
chips made from GaAsP on a
transparent GaP substrate. Due
to the large junction area, these
displays can be driven at high
peak current levels needed for
high ambient conditions or many
character multiplexed operation.
These displays have industry
standard packages, and pin
configurations and ± 1 overflow
display are available in all four
sizes. These numeric displays are
ideal for applications such as
Automotive and Avionic
Instrumentation, Point of Sale
Terminals, and Gas Pump.

10. The digits are categorized for luminous intensity with the intensity category designated by a letter on the side of the package.
11. The dominant wavelength, λd, is derived from the CIE chromaticity diagram and is that single wavelength which defines the color of the
device.

Electrical
These display devices are
composed of eight light emitting
diodes, with light from each LED
optically stretched to form
individual segments and a
decimal point.
The devices utilize LED chips
which are made from GaAsP on a
transparent GaP substrate.
Figure 5. Relative Luminous Intensity
vs. DC Forward Current.
These display devices are
designed for strobed operation.
The typical forward voltage
values, scaled from Figure 4,
should be used for calculating the
current limiting resistor value and
typical power dissipation.
Figure 4. Peak Forward Segment
Current vs. Peak Forward Voltage.
Expected maximum VF values, for
the purpose of driver circuit
design and maximum power
dissipation, may be calculated
using the following VF MAX
models:
VF MAX = 2.15 V + IPEAK (13.5 Ω)
For: IF ≥ 30 mA
VF MAX = 1.9 V + IDC (21.8 Ω)
For: 10 mA ≤ IF ≤ 30 mA
Temperature derated strobed
operating conditions are obtained
from Figures 1 and 2. Figure 1
relates pulse duration (tp), refresh
rate (f), and the ratio of maximum peak current to maximum
dc current (IPEAK MAX/IDC MAX).
Figure 2 presents the maximum
allowed dc current vs. ambient
temperature. Figure 1 is based on
the principle that the peak junction temperature for pulsed
operation at a specified peak
current, pulse duration and
refresh rate should be the same
as the junction temperature at
maximum DC operation. Refresh
rates of 1 kHz or faster minimize
the pulsed junction heating effect
of the device resulting in the
maximum possible time average
luminous intensity.
Mechanical
Contrast Enhancement
These devices are constructed
utilizing a lead frame in a
standard DIP package. The LED
dice are attached directly to the
lead frame. Therefore, the
cathode leads are the direct
thermal and mechanical stress
paths to the LED dice. The
absolute maximum allowed
junction temperature, TJ MAX, is
105°C. The maximum power
ratings have been established so
that the worst case VF device does
not exceed this limit.
The objective of contrast enhancement is to optimize display
readability. Adequate contrast
enhancement can be achieved in
indoor applications through
luminous contrast techniques.
Luminous contrast is the
observed brightness of the
illuminated segment compared to
the brightness of the surround.
Appropriate wavelength filters
maximize luminous contrast by
reducing the amount of light
reflected from the area around
the display while transmitting
most of the light emitted by the
segment. These filters are
described further in Application
Note 1015.
The time average luminous intensity can be calculated knowing
the average forward current and
relative efficiency characteristic,
η |PEAK, of Figure 3. Time average
luminous intensity for a device
case temperature of 25°C, I V
(25°C), is calculated as follows:
Worst case thermal resistance
pin-to-ambient is 400°C/W/Seg
when these devices are soldered
into minimum trace width PC
boards. When installed in a PC
board that provides RθPIN-A less
than 400°C/W/Seg these displays
may be operated at higher
average currents as shown in
Figure 2.

For DF = 1/5:

The radiation pattern for these
devices is approximately Lambertian. The luminous sterance
may be calculated using one of
the two following formulas.
IV(cd)
LV (cd/m2) = ––––––
A(m2)
= 4.5 mcd/segment
The time average luminous intensity may be adjusted for operating junction temperature by the
following exponential equation:
IV (TJ) = IV (25°C) e[k(TJ + 25°C)]
where T J = TA + PD • RθJ-A

Chrominance contrast can further
improve display readability.
Chrominance contrast refers to
the color difference between the
illuminated segment and the
surrounding area. These displays
are assembled with a gray package
and untinted encapsulating epoxy
in the segments to improve
chrominance contrast of the ON
segments. Additional contrast
enhancement in bright ambients
may be achieved by using a
neutral density gray filter such as
Panelgraphic Chromafilter Gray
10, or 3M Light Control Film
(louvered film).
