the ~t~l~t~r illuminnte~
Bach~lound of the Invention
~ lect-ic ~witche6 are co~ o 1y provided with ~ctn~tor6
for data input ~p~lir~t;on~ such as, for eY~mrle~ a keypad on a
tell ~h~ e Typically, it i6 desil ~~le to vary the apl,eal~ce of
the ~rt~Mtor for a variety of reason6 such as ~.oduc~

~eq~l..ements and di~ ~.t ~t;nn ~ L nearby ~rt~tor~
Back li~ht;n~ and llP~i~n~tors are tr~lit;~n~1ly used to vary
the ~l",eal~ce of the ~ct~tor to satisfy most app1ic~ffon~ ~ ;
DecignPtors in~ir~te and set apart the ~rt~t~r for a
25 s~,e~ rc purpose and may be illnmin~ted for viewing under

background. Co,lvel~ely, repres~ntecl as a negative image, the
graphics appear lighter than a contrasting darker
b~cl.~,o~ld. In some negati~e image Spp~ S~tion~, the
graphics are translucent for pe.~ll,i~.g the passage of light
5 and the bac~lo~d is opaque for blorlrine the passage of light.
FIGs. 1 and 2, FIG~. 3 and 4, and FIGs. 5 snd 6 show
first, second and third prior art t~ P8, le_~,iively, to
creste a negative image graphic ~e~rE~çnt~t;~n of a t3~P~ ns~t~r
on an Slrtv~Sltor.
Generally, FIas. 1, 3 and 5 each show a cross-sect;on
view of a keypad sl~qçmhly 100 wherein a translucent
Pl~SlPtompnc keypad 101 is sand~viched beS..e~ a bezel 103 and
a eircuit board 105. The P~ r~P- ;c keypad 101 indudes
slrt~Sl~nrs 107 protrudillg through co,~ ,o~ing hole6 in the
15 bezellOS. The~S~ct~St~rs107eachhaveatleastonec~n~ rt;ve
pad 109 for pro~v~ing Plect~icSll co~ b~t~.-En
co.,~ o~ing pairs of c~n~a~ 111 on the circ~it board 105.
Light sources 119 provide back lieht;ng for the ~rl~S~to~ D 107.
Generally, FIGs. 2, 4 and 6 each show a top view of the
20 ..e~ 2~Live image ~e~.~;..S~tors as n~e~als "1, 2 and 3" on the top
of the ~rt~l~tQrs 107 protruding l~. ou~;l. the holes in the bezel
103.
Although each of the three prior art techniques
c ~.te~1 create a negative image de~Ri~n~t~r on the Pct~l~tors
25 107, di~.~llces exi8t in the cv~e.~ge area of t~e dark
CO~ .b~ii~ bacl~.oL,lld on the ~rt-l~tors 107 and the
ill.. ;-.~ :~n of the s~ctn~tQrs 107.
In the first prior art eYs~mple, as sho~m in FIGs. 1 and
2, the negative image ~leRien~tQr is p.oduced by printing
30 (otherwise known as silk-screening) a dark colored layer of
m~ter~s-l 113 over an opt;~nS~l light colored layer of translucent
~te .;al 115. The dark colored layer 113 is partially masked to
produce an opDnine 117 in the dark colored layer 113 ~.l.c.e~ a
portion of t~e Ught colored layer 115 iB e~l-o~e~l The shape of
35 the mask p.c.duces the n eE;aLve image de~ien~t~ors as
..
2~1~72~
f~rhihite~ by n~nerals ~1, 2 and 3" on the top of the actuators
107.
Light sources 119, such as light emitting diodes,
generate light that passes through the keypad 1û1 to generally
min~te the llUlllelal6 ~1, 2 and 3" as well a6 the perimeter
of the ~rt~tors 107. By po~it;t)ning a light source 119 between
two ~ Pcent ~ckl~tQrs~ one light 80urCe ec~nr~mir~lly
contributes to the illnmin~t;on of more than nne Pct~l~tor.
Since the negative image pnnting proces~ is a two
(~im~pn~ ploce3a a narrow boarder 121, void of any colored
layer, is .,.~ D;~~ at the ~.~el,er of the top of the ~ t~rs
107 to ensure that the colored layer doe not run dovrn the sides
ofthe ~ ol~ 107. II1 80me ;~ -re~, thi6 is viewed a6
llns~c;~p! ~hle, becpl-cç it is desirable to have the sides as well
as the top of the ~ ~r6 107 e~hibit the dark contra6ting
bacl~l ou~d.
In the second prior art e~mrle, a6 shown in FIGs. 3
and 4, the negative image ~e~ien~tor is p.oduced by ~ poEine
an opt;~n~l light colored layer 305 on at least the top of the
~c~ to~6 107 followed by ~ poEirg a dark colored layer 307 on
the entire top side of the keypad 101 indulh~ all side6 of the
~t~l~tQrS 107. The dark colored layer 307 is then
coll~e~ on~lly etched ~rith a laser to p.oduce sn opPnin~ 309
in the dark colored layer of 307 ~. Le~e~ the light colored layer
26 305 i8 P~08e~ Controlled laser etching ~.oduces the nc6~tive
image APcign~t~ rs as exhibited by numerals "1, 2 and 3~ on the
top side of the o~ o, ~ 107. Thus, the dark contra6ting
bacl.g.oulld for the ne~dli~O image (lP,R;~ to~ i6 created not
only on the top but also on the 6ides of the o~ t,ol~ 107.
3û A light source 119 is ~liRpo~ed s~e- :r.- ~lly b~nP~tll each
t~tor 107 to back light the numerals "1, 2 and 3~. However,
since the entire top side of the keypad 1û1 i8 CG.~.ed with the
dark colored layer, light from the light 60urce6 119 can only
pass through the keypad 101 to illllmin~te the numerals Ul, 2
and 3~ and no light i8 ~ d to ill~min~te the ~e.. e~el of
211~7~
the act~t~rs 107. Additionally, specific lighting increases
c06t, parts count, labor, culTent drain and the potential for
defects when cv~l.pared to the general lightine technique as
show and described in FIG. 1.
In the third prior art eY~mrle, as shown in FI(:~. 5 and
6, the ~e~Lve image de~ign~t~r i~ produced by a double ~hot
insert molding process. The ~l~ci~r portion of the
tll~rs 107 are molded intlpppnd~ntly of the keypad 101 then
~tt~ d to the keypad 101 a6 show~inFIG. 5. The ~ tors
107 are molded from a similar material to the keypad 101 and
moleclll~rly bonded to the keypad 101 during a secon~
molding operation. ~ ively, some ~rt~tQrs 107 are :~
molded from a di~e.~n~, m5~teriS~l firom the lceypad 101 and
adhe~ively bonded to the keypad 101. The ~ tors 107 are
1~ opaque pro~lu~ng a dark C.)nl,laE~I~g ~ack~;~vv~d on their
~ l-osed ~ e~ A light colored layer 501 i6 ~icposecl on the
top of 1 he r~ ~ ~to, ~ 107 to produce the negative image
~e~ tQr. Thus, the dark coll~sling br.~E;lo~d for the
lle~l;~ image ~eRign~tor is created not only on the top but
also on the sides of the ~ tors 107.
However, since the 5~rt~ tor is opaque, light from the -
light sources 119 only illllminS-teE the ~.;,.~ele~ of the -
s~r~ t~rs 107 and no light is pe.,.l-~Led to illllmins~te the ~ :~
l~u~c~lB~l~ 2 and 3~.
In the three prior ~rt eY5~mrle~ described hereinabove,
the actuators 107 are provided with an illllmin~ted negative -~
image ~lA~ n~tQr. In the first ey~mple~ both the graphics and -
the ~ Fte~ of the o~ ~..A~ 0- are ill-lmins-ted but the dark
conL ~~;ng bacL~l o. nd i6 not l.res_,lt on the sides of the ~ - :
30 ~ tor. In the second ~Y~mp'e the dark contrasting
b~ch~lou--d is ~JlC~_,lt on both the top and the sides of the
o~ but only the ~l..pLcs are illllmin~te~ Finally, in the
third PY~mple~ the dark contl~sL~l~ b~loul-d i8 p,esent on
both the top and the sides of the ~rtu~t,or but only the perimeter
35 ofthe ~rt~l~toris illnmin~t~

Therefore, there i~ a need for an de~ign, t~Ar having a
dark contra~ting ba~lound p,e~_,.t on both the top and the

Detailed Description of a l'le~rled ~.mho~lin~çnt
FIGs. 7 and 8 are cros6 sect;-~n~l and top views,
respectively, of a fl~cigns~or 700 hsving negative image

invention. FIG6. 9 and lO are cross sect;on~l and top views,
/,eclively, of a dPci~nntQr 900 having posiLive image
graphics 1000 and constructed in aCCOLdanCe with the present
invention.
A primary feature of the novel de~ign~tQ-s 700 and 900 i~s
that the upper sides surfaces 709 that are visible to the user are
opaque. This feature en~hleE light to travel freely through the
tors to ill~ Ate both the laphic~ 800 and 1000 on the
top surface 703 and the perimeter of the ~eRi~n~tc~r. Thus, the
15 novel des~i~n~tors 700 and 900 vv~.co",e the ~leff~n~e6 of the
aforemPnt;~nP~l prior art ~le~ tors. The present ~pp~ tinn
~;R~Cr~e6 various aspects of t~e opaque coverage area on the
~lecign~t~r6 700 and 900, the i~ min~t;-~n thereof and method
for ms~kinE~ the same to produce a unique and desirable effect
20 unlike any other.
The de~ien~tors 700 and 900 may be used in a variety of
~rrlirs~tion,. to in-lic~t,~ nd set apart user interface features
such as the keypad ~ tors and nnnn~tV~ting display
in-licP~,Qrs, for example.
The de~i~nt tQrs 700 and 900 each have a ~--hE~ lly
translucent substrate 701. A top surface of the substrate 703
ha~ a El~h6t~nti~11y translucent portion 705 and a gubstsnti~lly
opaque portion 707. Upper side ~u, ~ceR of the 6ubstrate 709
adjGillil~ the t,op surface 703 are sllhstsnti~lly opaque and
30 preferably extend bet~.een one and three millim~ters below the
top surface of the sub6trate 703. Lower side surfaces 711 of the
substrate ~dj~inin~ the upper side surfaces 709 are
8llh~t~nt;~l1y translucent.
The tr~nRlvcPnt 705 and the opaque 707 portions on the
35 top surface 703 on the deRi~ or 700 produce negative image
, ,
2~1 ~72_~
graphics 800 as 6hown by example as a white tnangle vnth a
dark bacl~lou"d. The translucent 705 .~nd the opaque 707
portion6 on the top surface 703 on the de~ign~tor 900 produce
yosiLi'vd image graphics 1000 as shown by PY~mrle as black
5 lettering "SND" with a light bacl~g,..)"l~d. Thus, the preeent
invention benQfiri-o-lly produce~ two new graphic pre6entations
wherein the ~loRtgnAtor~ 700 and 900 each have opaque side
surface6 709.
The dP~ no-tJ~rs 700 and 900 are preferably, but not
1 0 nPcee~so-rily~ formed from two parts. A first translucent part
713 having top 703, bottom and side 709 surfaces is formed. An
opaque substance, such as c(~l~v~ rnol ink, i6 ~i~pOBed on the
top surface 703 and the side ~u~faces 709 of the first formed
part 713 to l"od-lce the opaque portion 707. A second
1 5 sll~e~ont;-o-lly tr~nRlnrent part 716 having tr-o-nRlllrent top and
side 6~. f~-- e~ is formed. The fir~t 713 and second 715 parts are
preferably made from any of a vanety of elastic mater.ials
re~e~nhl;..g rubber. I~te bottom surface of the fir~t formed part
713 and the top surface o~the second formed part 715 are
20 co~rled together to form the deRi~n~to~ 700 and 900. Either
before or after the first formet part 713 and the second foImed
part 715 are coupled together, some of the opaque s~ -h~ re i8
~elecL~ ely removed fi om the top surface 703 to reveal the
translucent portion 705. Selective removal of the opaque
25 substance iB preferably ~ccompli~hed using conv~ l laser
etchir~ techniques.
A tr~nclvrPnt a-~h~'~..re 701, such as collvenl~io~lal ink,
is opt;~ nAlly rli~pssed on the translucent first part 713 before
the opaque s~lh~tsnc~ is AicposeA? Thus, the translucent
30 portion 705 having a tr~n6lvrPnt sllh~?t~?nce ~ pose~ thereon is
revealed during the laser etching process. The translucent
svh~t~nce 717 advantageou~ly provides cvl~ sl, ~epin~t the
opaque portion 707 under sllh~??tsntislly illllmin~ted ~?mhiPnt
lig.h~ine conditions such as Eunlight during the day time.
