Cathode ray tube application s are increasing indiversity and sophisti ca ti on to answer th e need f or abetter m an -m ac hine interface. Rece nt monochromeand color graphic disp lays for ai rcraft cockpits, forcomputer readouts, and for reco rding have chall enged
th e ing enuity of CRT magnetics design e ngineers.

APRIL, 1982

Deflectio n yokes continue to improve to meet thesemore soph isticated requirements . A comparison of theyoke parameters of 15 years ago with t hose of today
show the steady improvement in spot growth, rapid
settlin g, and geometr ica l symmetry. Color yokes inparticular, with very tight converge nce specificatio ns,
typify th e demand for more f lexibility in t he des ign andmore precision in the control of both front and rear
mag netic fr inge fields.
Focus coils have been developed with the ability t ohandle large dynam ic changes in flux without the lag
cha racterist ic of earlier designs. The re-emergence of
perma nent magnet focus devices has resulted from theimprovement in ceramic magnetic materials.
Finally, t here is an increasing use of low power
stigmators and al ignment magnet s to correct imper f ecti ons in CRT guns .

CRT Magnetic Components A Review of Progress
Dr . Henry 0 . M arcy, Chairman of the Board
Syntronic Instrume nts, Addison, IL
Th is discussion covers recent development s in m agnetic components f or modern CRTs.

Deflection Yokes
Let us first look at deflection yokes. Of the many yoke
parameters that are of concern to the display designer,
there are thre e that affect the quality of a display. These
are: (1) spot growth; (2) rapid settling of the electron
beam; and (3) geometrical precision.

Yoke Spot Growth
Let us consider first spot growth due t o astigmatism .
Simple analysis reveals three basic causes of astigma tism . These are as fo llows:a) Non-uniformity of magnetic field ;b) Effect of electron beam convergence; andc) M isalignm ent of the incident electron beam
re lative t o th e yoke.
For deflectio n angles greater than 20 degrees, them ost important factor is control of transverse field
uniform it y throughout the !'!ntire path of th e electron
beam, including front and rear magnetic fring e fields.
The fring e fields become increasingly more importantas the yoke fi e ld length is reduced to all ow greater
deflection ang les. A useful relationship for appraising
the spot growth due to non-uniformity of transverse
fi eld i s:

is of practical value. Empirical studies using models
constructed with different core conf igurations havebeen the preferred approach . Recently, improved computer techniques offer a viable alternative. Preliminary
eva luation of innovative yoke configurations using anempirical approach is still faster and more economical.
The cathode ray tube itself is a marvelous analogue
instrument for the critical measurement of spot growthwith deflection . Sophisticated " pepper pot" CRTs withspecial gun designs greatly imp rove the empiricalapproach.

Figure 5 . Rad ial Covergence

Employing both these design techniques, variationand control of the fringe field by shaping the corematerial has made possible a considerable improve mentover the last few years. (See Figure 4). Today, improved
convergence in shadow mask color CRTs is entirely
analagous to improved spot growth in monochrome
CRTs and the same techniques apply.
Another property closely related to spot growth ofgreat recent interest is the reduction of the amount ofdynamic focus required for a given glass configuration.
The naive assumption that the cu rvature of focus field isabout the center of deflection proves entirely false . The
actual curvature of this field is consi derably greater.
Although affected by the shape of the forward magneti cfringe field, efforts to improve this property of yokes has
met with only moderate success. Recent yokes require
about three-quarters the dynamic focus voltage rangeof earlier yokes.

Radtal Convergence

Rap id settling , together with very low res idual
magnetism, is an absolute requirement of th e strokewritten displ ay popular today in avionics, computer
terminals, and typesetting mach ines. Improvement inavailable ferrite core materials has reduced the resid ual
magnetism of yokes to quite acceptable limits, often
better than 0.01 % as compared w it h typica l earlier
yokes where 0.1 % was the rule. Rapid settling on theother hand is accompl ished with higher qual ity ferrite
cores and by shield ing the stray fields of the yoke fr om
its surround ing environment. It is now common toprovide comp lete f errite sh ielding. This has resulted inyoke settl ing times to as little as 0.05% in 2 to 3
microseconds.

New Style Core

Yoke Geometry

Ferrite Shielded Yoke

Present day display geometrical accuracy req uires
greater precis ion in the co nstruction of both CRT a ndyoke, together with exce llent alignment. The trend of
the display ind ustry is toward CRT, yoke, and shieldassemblies. Alignment of these components can employ
compensation for a co mbination of CRT and yoke errors
to make the whole s uperior to the parts. Better ma nufacturing techniques have improved the yoke itself, but
credit f or improved geometrical perform ance today
must be given t o the use of assemb ly t echn iqu es where
yoke, CRT, and shield are potted together.
Finally, many other parameters are part of the yoke
design problem . Comparisons in the accompanying
chart will show some of the trends. (See Figure 7.)
Contrary t o popular be lief, the efficiency of deflection
yokes has not improved if we define efficiency as t heenergy required t o cha nge the magn etic field by a given
amou nt w ithin a volu me determined by the glass
configu ra tio n of a particular CRT. Th is energy is u2; 2joules and the deflecti on resulting is related again to the
CRT geometry and the anode pot ent ia l. With thisdefinition, yokes built in the 1950's were already 95%
efficient. The appa ren t improvement has resu lted from
improved CRT neck contours.

Figure 6 . Ferrite Shielded Yoke

Focus Components
Elect romagnetic focus devices have the advantage ofa larger lens diameter resulting in much lower sphericalaberration co mpared with electrostatic focu s CRT guns.
The disadvantage is a high energy req u ir eme nt. With
the development of bett er cerami c magnetic materials,

Trendspermanent magnet devices are now practical from both
quality and cost considera ti ons.
High energy dynamic focus coils with rapid settli ng
have been needed f or penetration phosphor CRT devices.
Th e newe r designs refocus the beam rapidly as theanode potential is cha nged to alter co lor orpersistence.
Stigmators are becoming a usef ul adjunct to CRTs
especia lly since low power permanent magnettypes are
now available.
Matched with th e improvem ent in deflection drive
transistors, modern day magnetics make possible better
CRT displays for t omorrow.

MID-ATLANTIC CHAPTER's Peter Hahn, Trea surer,
heeded your editor's plea for news of technica l meetings
and responded bri lli antly. At the January 12 meeting ,th e featured speakers were Dr. J oseph Shay of Be ll
Laboratories and Robert Giglia of American Cyanamid,
discussing advances in electronics displays. Dr. Shay
discussed th e desirable properti es of irid iu m oxide as apassive display medium . It is exceptionally st ab le andhas a fast intrinsic response above - 20° C. A prototype
seven -segment display was described. Rob~rt Gigli a
discussed performance improve ments in WO e l ~ctro ­ch romic di splays and how th e problem of WO film
degradation with su lphuric acid electrolyte was overcome by employi ng po lymeric proton conductors. Utilizing a nove l carbon paper counter -electrode, the newelectrolytes foster simple construction and long switch ing life. Device design and performance were discussed .
These speakers were introduced by Dr. Gottfried Haache,
American Cyanamid.
On February 16, a l arge audience of S ID m embers andguests heard Peter Seats, president of Thomas Electronics, discuss " Larg e Screen Electronic Displays Past, Present. and Future. " The evolution of projectiont e levision syste ms over the past 30 yea rs wa s presented
and included light va lve devices, color wheel techniques,
and other unusual designs. Thi s revi ew was followed bya system characterizati on of recentl y deve loped l arge

Transistors in Flat Panel Displays. " In flat panel displays,
where matrix display elements must be addressed,
connecti ons may be reduced and multip lexing enhanced
by use of thin -film t r ans istor (TFT) techno logy, apromising solution . TFTs are formed at th e intersectionof the vertical and horizontal bus li nes, acting as an
ON -OFF switch. The TFT matr ix ci rcuit was analyzed
and requ irements of the device characteristics described. Typically, TFTs are fabricated on glass subst rates, by evaporat ion throu gh apertu re masks or byphotolithograp hic et ching. Comm only used processes
were reviewed. TFT displays have been demonstrated
and work ing displays obtained. Their performance wasdiscussed by Dr. Luo.

Resolution Graphics Upgradedfor Easier Cursor Positioning
and Sharper Images
Two new hardware enhancements to t he DOMAIN(Distributed Operating Multi -Access Interactive Network) computer system have been introduced by Apo llo
Computer Inc., Chelmsford , MA.
Apollo's DOMAIN computer system has been enhanced with a keyless touchpad, integra l with the
keyboard, that permits an operator to position the cursor
quickly and accurately by simply moving the tip of afinger across the pad surface. In add ition, a new black
and white monitor with an extremely crisp, sharp image
produces a h ig h resolution bit-mapped display (approximately 100 dots/ inch, both horizontal and vertical).
Apollo 's DOMAIN features a 32-bit computing architecture based on a local area network of single-user work
stations or nodes. Running up to 15 programs, each up
to 9 Mbytes, simultaneously, every node incorporates
high resolution, monochromatic graphics capabil ity w ith
1 Mbit of independent di splay memory. Transparent
access to resou rces is provided via a network-wide
demand-paged virtual memory operating system at a 12
Mbit/ sec data rate .

Color is Coming!
For high performance CRT displays
Yes. Right here in America weare working hard on developing
deflection yokes for industrial/commercial and military color
CRT display applications where
quality and performance are
more important than mass
production.
Color displays are many times
more complex than
monochromatic displays
because of the critical interface
between CRT, yoke andcircuitry. And quality displays
are too demanding forconventional color TV type yokes .

With a unique blend of
teamwork between display
designer, CRT designer andour experienced deflection
yoke engineers we are meetingthe challenge of highbrightness, high resolution ,high speed and pure, accurate,
full color. Typical areas ofdevelopment are high speed
graphic terminals, flight
simulators and cockpit displays.
Syntronic is ready to team up
with your display engineers todevelop a high performancecolor yoke for your application.
Call Dave Brown at
312-543-6444 for more
information.

For several years Syntronic
Instruments, Inc. has beenworking with major international
manufacturers of full-color
shadow mask tubes to develop
high performance color yokes.
