DESCRIPTION
The HDSP200XLP are four digit 5 x 7 dot matrix serial input alphanu-
meric displays. The displays are available in red, yellow, high efficiency
red, or bright green. The package is a standard twelve-pin DIP with a
flat plastic lens. The display can be stacked horizontally or vertically to
form messages of any length.
The HDSP200XLP has two fourteen-bit CMOS shift registers with
built-in row drivers. These shift registers drive twenty-eight rows and
enable the design of customized fonts. Cascading multiple displays is
possible because of the Data In and Data Out pins. Data In and Out
are easily input with the clock signal and displayed in parallel on the
row drivers. Data Out represents the output of the 7th bit of digit
number four shift register The shift register is level triggered. The like
columns of each character in a display cluster are tied to a single pin
(see Block Diagram). High true data in the shift register enables the
output current mirror driver stage associated with each row of LEDs
in the 5 x 7 diode array.

DESCRIPTION
(continued)
The TTL compatible V
B
input may either be tied to
V
CC
for max-
imum display intensity or pulse width modulated to achieve
intensity control and reduce power consumption.
In the normal mode of operation, input data for digit four, column
one is loaded into the seven on-board shift register locations one
through seven. Column one data for digits 3, 2, and 1 is shifted
into the display shift register locations. Then column one input is
enabled for an appropriate period of time, T. A similar process is
repeated for columns 2, 3, 4, and 5. If the decode time and load
data time into the shift register is t, then with five columns, each
column of the display is operating at a duty factor of:
T+t, allotted to each display column, is generally chosen to
provide the maximum duty factor consistent with the mini-
mum refresh rate necessary to achieve a flicker free display.
For most strobed display systems, each column of the display
should be refreshed (turned on) at a minimum rate of 100
times per second.
With columns to be addressed, this refresh rate then gives a value
for the time T+t of: 1/ [5 x (100)] =2.0 msec. If the device is oper-
ated at 5.0 MHz clock rate maximum, it is possible to maintain t
<
T.
For short display strings, the duty factor will then approach 20%.

Cleaning the Displays
IMPORTANT--Do not use cleaning agents containing alcohol
of any type with this display. The least offensive cleaning solu-
tion is hot D.l. water (60
C) for less than 15 minutes. Addition
of mild saponifiers is acceptable. Do not use commercial dish-
washer detergents.
For post solder cleaning use water or non-alcohol mixtures
formulated for vapor cleaning processing or non-alcohol mix-
tures formulated for room temperature cleaning. Nonalcohol
vapor cleaning processing for up to two minutes in vapors at
boiling is permissible. For suggested solvents refer to App-
note 19 at www.infineon.com/opto.

Thermal Considerations
The small alphanumeric displays are hybrid LED and CMOS
assemblies that are designed for reliable operation in commer-
cial, industrial, and military environments. Optimum reliability
and optical performance will result when the junction tempera-
ture of the LEDs and CMOS ICs are kept as low as possible.
Thermal Modeling
HDSP200XLP displays consist of two driver ICs and four 5 x 7
LED matrixes. A thermal model of the display is shown in Fig-
ure 5. It illustrates that the junction temperature of the semi-
conductor = junction self heating + the case temperature rise +
the ambient temperature. Equation 1 shows this relationship.
Figure 5. Thermal model
See Equation 1 below.
The junction rise within the LED is the product of the thermal
impedance of an individual LED (37
C/W, DF=20%, F=200 Hz),
times the forward voltage, V
F(LED),
and forward current I
F(LED),
of 1314.5 mA. This rise averages T
J(LED)
=1
C. The table below
shows the V
F(LED)
for the respective displays.
The junction rise within the LED driver IC is the combination of
the power dissipated by the IC quiescent current and the 28
row driver current sinks. The IC junction rise is given in
Equation 2.
A thermal resistance of 28
C/W results in a typical junction
rise of 6
C.

For ease of calculations the maximum allowable electrical oper-
ating condition is dependent upon the aggregate thermal resis-
tance of the LED matrixes and the two driver ICs. All of the
thermal management calculations are based upon the parallel
combination of these two networks which is 15
C/W. Maxi-
mum allowable power dissipation is given in Equation 3.

Optical Considerations
The light output of the LEDs is inversely related to the LED
