Description

The DLR/DLO/DLG2416 is a four digit 5 x 7 dot matrix display module with a built-in CMOS integrat ed circuit.This dis-

play is X/Y stack able.

The integrat ed circuit contains memory, ASCII ROM decoder, multiplexing circuitry and drivers. Data entry is asyn-

chronous and can be random. A display system can be built using any number of DLX2416s since each digit can be

addressed independentl y and will continue to display the character last stored until replaced by another.

System interconnection is very straightforward. The least significant two addre ss bits (A0, A1) are normally connected

to the like-named inputs of all displays in the system. With two chip enables (CE1 and CE2) four displays (16 charac-

ters) can easily be interconnected without a decoder.

Data lines are connected to all DLX2416s directly and in parallel, as is the write line (WR). The display will then

behave as a write-only memory.

The cursor function causes all dots of a digit position to i lluminate at half b rightness. The cursor is not a charact er, and

when removed the previously displayed character will reappear.

The DLX2416 has several fe atures superior to competitive devices. True ’’blanking“ allows the designer to dim the dis -

play for more flexibility of display presentation. Finally the CLR clear function will clear the cursor RAM and the ASCII

character RAM simultaneously.

The character set consists of 128 sp ec ial ASCII characters for English, German, Italian, Sw edish, Danish, and Norwe-

gian.

All products are subjected to out-goi ng AQL’s of 0.25% for brightness matching, visual alignment and dimensions,

0.065% for electrical and functional.

5 kHz Blanking Frequency

Loading Data

Setting the chip enabl e (CE1, CE2) to their true state will

enable data loading. The desired data code (D0-D6) and

digit address (A0, A1 ) must be held stable during the

write cycle for storing n ew data.

Data entry may be asynchronous and random. Digit 0 is

defined as right hand digit with A1=A2=0 .

To clear the entire in ternal four-digit memory hold the

clear (CLR) low for 1.0 µs. All illuminated dots will be

turned off within one complete display multiplex cycle,

1.0 ms minimum. The clear function will clea r bo th the

ASCII RAM and the cursor RAM .

Loading Cursor

Setting the chip enables (CE1, CE2) 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. Th e cu rsor (CU) pulse width should not be less

than the write (WR) pulse or erron eous da ta may appear

in the display.

If the cursor is not requ ired, the cursor enable signal

(CUE) may b e ti ed low to disab le 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 contents of cursor

memory.

Display Blanking

Blanking the display may be accomplished b y loading a

blank or space into each digit of the display or by using

the (BL) display blank input.

Setting the (BL) inp u t low does not affect the contents of

either data or cursor memory.

A flashin g circ u it can easily be constructed using a 555

as table multivibrator. Figure 4 illustrates a circuit in

which varying R2 (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 f ast to not interfere

with the internal clock. The dimming signal frequency

should be 2.5 kHz or hi gher. Dimming the display also

reduces power consumption.

An example of a simple dimming circuit using a 556 is

illustrated in Figure 5. Adjusting potentiometer R3 will

dim the display by changing the blanking pulse duty

cycle.

Electrical and 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 lin e while they change display

states. Th e common pr actice is to place . 01 mF capa citors clos e to

the displays across VCC and GND, one for each display, and one

10 mF capacitor for every second display.

ESD Protection

The silicon gate CMOS IC of the DLX2416 is quite resistant to

ESD damage and capable of withstanding discharges greater than

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 DLX2416 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 n ot e xceed 93°C on t he solder side of t he PC boar d

or a package surface temperature of 85°C. Water soluble organic

acid flux (except carboxylic acid) or rosin-based RMA flux without

alcohol can be used.

Wa v e temperature of 245°C ±5°C with a dwell between 1.5 sec. to

3.0 sec. Exposure to the wave should not exceed temperatures

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

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 detergents.

For f aster cleaning , solv ents ma y be used. Carefully select an y sol-

vent as some may chemic ally atta c k the n ylon pa c kag e . Maximum

exposure should not exceed two minutes at elevated tempera-

tures. Accep table solvents are TF (trich orot ribl uore thane ), 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 conta in alco hol, meth anol , methylene chlo-

ride, ethanol, TP35, TC M, TMC, TM S+, TE, or TES. Si nce many com-

mercial mixtures exist, cont act a so lvent v en dor for chemical

composition inf ormation. 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 Chemical , Midl and, MI ;

E.I. DuP ont de Nemours & Co., Wilmington, DE.

For further information ref er to Appnotes 18 and 19 at

www.osram-os.com.

An alternative to soldering and cleaning the displa y 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 b y lon ger S IP socke ts or DIP soc k e ts wh en a vailable fo r uni-

form pac kage alignment. Soc ket man ufa cturers are Aries Electronics ,

Inc., F renchtown, NJ; Garry Manufacturing, New Brunswich, NJ; Rob-

inson-Nugent, Ne w Alb an y, IN; and Samtec Elect roni c Ha rdw are ,

Optical Considerations

The 0.200" high characters of the DLX2416 gives readability up to

eight feet. Proper filter selection enhances readability over this dis-

tance.

Filters enhance the contrast ratio between a lit LED and the char-

acter background intensifying the discrimination of different char-

acters. The only limitation is cost. Take into consideration the

ambient lighting environment for the best cost/benefit ratio for fil-

ters.

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 wa y to

strengthen contra st r at ios.

The DLR2416 is a stand ar d re d di splay and should be matched

with long wavelength pass filter in the 600 nm to 620 nm range.

The DLO2416 is a high efficiency red display and should be

matched with a long wavelength pass filter in the 470 nm to 590

nm range. The DLG2416 should be matched with a yellow-green

band-pass filter that peaks at 565 nm. For displays of multiple col-

ors, neutral density gray filters offer 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 not to ov erheat the plastic filter by allo wing for

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 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 Prod ucts of Califor nia,

Santa Monica, CA; .E.E.-Atlas, Van Nuys, CA.
