Membrane hloov yog ib qho hluav taws xob hloov rau txoj siav ib tug Circuit Court rau hauv thiab tawm. Nws txawv los ntawm ib tug txhua yam mus, uas yog feem ntau yog ua los ntawm tooj liab thiab yas qhov chaw: ib tug membrane mus yog ib tug Circuit Court sau rau ntawm tus tsiaj los yog Ito . Tus number case siv rau kev tshuaj ntsuam luam ntawv yog feem ntau yog tooj liab / nyiaj / graphite sau thiab yog li ntawd conductive.
Membrane keyboards yog tus neeg siv-khoom interface hlauv taws xob uas tso cai rau rau kev sib txuas lus ntawm commands los ntawm cov neeg rau hluav taws xob pab kiag li lawm. Membrane keyboards yuav xav li cas txog li ib qeb ntawm interface hlauv taws xob alongside kov ntxaij, yas twj remote controls, toggle keyboards thiab ntau lwm yam kev tswj systems. Interface hlauv taws xob yuav ua tau raws li tej yam yooj yim raws li tactile keyboards rau kev tswj teeb pom kev zoo, thiab lawv muaj peev xwm ua tau li tham li membrane twj remote controls thiab hloov panels siv rau cov computers.
Lub ASTM sij ib daim nyias nyias hloov raws li "ib lub momentary hloov ntaus ntawv nyob rau hauv uas tsawg kawg yog ib hu yog nyob rau, los yog ua los ntawm, ib tug saj zawg zog substrate."
Ib tug membrane hloov feem ntau muaj 4 los yog ntau tshaj khaubncaws sab nraud povtseg. Lub sab saum toj txheej ntawm ib tug nyias nyias mus yog lub graphic interface ntawm cov neeg siv thiab cov tshuab. Cov lwm tseem ceeb heev txheej yog ib tug luam Circuit Court. Qhov no kuj yog ib tug flex Circuit Court ua los ntawm tooj liab thiab polyimide khoom. Cov khaubncaws sab nraud povtseg yog feem ntau tuaj txoos ua ke siv siab-sensitive adhesives txawm hais tias pheej yig designs yuav tsum tau muaj ua ke los ntawm lwm yam cov neeg kho tshuab txhais tau tias xws li ib tug keyboard vaj tse nyob. Tiv tauj ntawm ob ib co kua nplaum yuav ua los ntawm ib tug luam shorting ncoo los yog los ntawm ib tug hlau dome uas stands rau ob txhais ceg.
Backlighting
Muaj peb txheej txheem kev rov qab teeb pom kev zoo membrane keyboards.
Cov kev xaiv thawj yog siv lub teeb emitting diodes (LEDs) kom rov qab lub teeb. Txawm li cas los, LEDs tsim kaj me ntsis thiab yog tsis haum rau tag nrho rov qab teeb pom kev zoo ntawm ib tug vaj huam sib luag, tab sis, theej li qhia teeb. LEDs yuav yog tau nto mounted rau hauv Circuit Court txheej los yog muab tso rau hauv ib tug nyias muaj nyias ib LED txheej.
Ib tug thib ob xaiv yog kho qhov muag fiber . Nyob rau hauv ib tug raug tsim, ob los sis ntau khaubncaws sab nraud povtseg ntawm woven fiber-optic daim ntaub yog siv los tsim ib lub teeb-emitting cheeb tsam. Lub fibers los tawm ib kawg ces bundled rau hauv ib lub voj voog ferrule thiab ua ke rau ib los yog ntau tshaj LED teeb qhov chaw. Tej thaj chaw deb teeb qhov chaw muaj 10,000 100,000 teev ntawm lub neej. Kho qhov muag fibers tsis cuam tshuam los ntawm extremes nyob rau hauv av noo (0% mus rau 100%) los yog kub (-40 rau + 85 DEG C).
Qhov thib peb txuj kev xaiv no yog siv electroluminescent (EL) teeb. Lawv yog cov tsawg luv nqi piv rau fiber optics thiab muaj lwm yam kev tsim ua yooj yim. Cov xim ntawm lub teeb tawm txim liab los ntawm ib tug EL teeb yuav txawv nyob ntawm seb lub phosphors uas yog siv. Tej yam xim xiav / ntsuab thiab daj / ntsuab, dawb, xiav thiab txiv kab ntxwv. EL teeb muaj ib tug ib nrab-lub neej ntawm kwv yees li 3000-8000 teev nyob raws li qhov zoo tshaj ntawm cov phosphor. Thaum lawv ncav cuag lawv cov ib nrab-lub neej, lub ci ci pib ploj sai. EL teeb yog li tsis yog ib tug zoo xaiv yog hais tias tus teeb yog nyob rau ib ncua sij hawm ntawm lub sij hawm. Fading los yog flashing yuav ob npaug rau lub neej ntawm lub teeb.
daim ntawv sau npe
Classic daim ntaub ntawv ntawm daim nyias nyias keyboards xws li microwave cub vaj huam sib luag, huab cua txias tswj vaj huam sib luag, TV tej thaj chaw deb tswj tau lwm yam tactile tswv yim ntawm lub lag luam yuav tsum yog muab los ntawm embossing lub sab saum toj tus tsiaj txheej los yog embedding hlau snap ncaws, polyester ncaws los yog txoj kev ua rau cov duab txheej.
Cov kev pab cuam ntawm daim nyias nyias keyboards muaj xws li yooj yim tu, kev sib khi muaj peev xwm thiab lawv cov uas tsis muaj profile. Membrane hloov yuav tsum tau siv ua ke nrog rau lwm cov kev tswj systems xws li kov ntxaij, cov twj remote controls, teeb pom kev zoo, thiab lawv muaj peev xwm kuj yuav nyuab ib yam li cov daim nyias nyias twj remote controls thiab mus panels nyob rau hauv mobiles thiab computers. Lawv yog cov txhim khu kev qha, zoo, tsawg-nqi neeg siv interfaces, haum rau ib tug ntau yam ntawm cov khoom, thiab muaj nrog rau ntau cov tswv yim xaiv.
Nyob rau kev lag luam thiab daim ntawv thov, daim nyias nyias keyboards kuj raug xa mus rau raws li daim nyias nyias twj remote controls thiab daim nyias nyias keypads.
