Hais txog kov npo

Lub vijtsam kov, tseem hu ua "kov screen" lossis "kov vaj huam sib luag", yog ib qho inductive kua siv lead ua cov khoom siv uas tuaj yeem tau txais cov tswv yim tawm tswv yim xws li kev sib cuag. Thaum kov cov duab khawm ntawm lub vijtsam, lub tactile cov lus tawm tswv yim ntawm lub vijtsam tuaj yeem tsav ntau yam kev sib txuas ntawm cov khoom siv raws li cov kev pab cuam ua ntej, uas tuaj yeem hloov kho cov khawm khawm panels thiab tsim cov suab nrov thiab cov yeeb yaj kiab los ntawm cov kua siv lead ua kua.
Txij li thaum qhov tshwm sim ntawm lub ntiaj teb no qhov ntxov tshaj plaws resistive kov screen nyob rau hauv 1974, nrog rau txoj kev loj hlob ntawm technology thiab kev loj hlob ntawm daim ntawv thov, ntau yam kov technologies tau tshwm sim los hloov mus rau ntau yam lag luam thiab theem ntawm kev siv. Niaj hnub no, kev lag luam kov npo thev naus laus zis tau tshwm sim, suav nrog cov ntxaij vab tshaus kov, capacitive kov cov ntxaij vab tshaus, infrared kov cov ntxaij vab tshaus, nto acoustic yoj (SAW) kov cov ntxaij vab tshaus, thiab lwm yam, thiab tau siv dav hauv ntau lub teb xws li xov tooj ntawm tes, ntsiav tshuaj, khw muag khoom. kev lag luam, pej xeem cov ntaub ntawv nug, multimedia cov ntaub ntawv systems, khoom kho mob, industrial automation tswj, kev lom zem thiab catering kev lag luam, tsis siv neeg ticketing system, kev kawm ntawv, thiab lwm yam.
