Qhov txawv ntawm Resistive thiab Capacitive Touchscreens yog dab tsi?

Qhov projected-capacitance technology feem ntau dominates touchscreen ntug, thiab ua inroads mus rau hauv lub resistive touchscreen realm ntawm tus nqi qis apps nrog cov ntxaij vab tshaus loj.

Smartphones thiab ntsiav tshuaj tau ua kom kov-enabled interfaces ib feem tseem ceeb ntawm peb lub neej, nrog kov sai heev los ua tus neeg siv interface ntawm kev xaiv thoob plaws ntau daim ntawv thov thiab kev lag luam. Ib qho yooj yim kov-raws li interface tsis yog ib qho tseem ceeb sib txawv feature rau high-end daim ntaub ntawv, tab sis, thiab nce kev sib tw ntawm OEMs yog tus nqi qis. Touchscreen systems sawv cev rau ib qho ntawm cov nqi kim dua hauv cov ntawv thov nqa tau yooj yim, thiab lawv yuav tsum tau tsim los ntawm tus nqi qis dua thaum tseem muab kev ua haujlwm siab.

Feem ntau cov touchscreens siv cov khoom siv hluav taws xob los yog qhov projected-capacitance touch technology. Resistive touchscreens, uas tso cai rau ob tus ntiv tes thiab tsis yog ntiv tes tawm tswv yim (piv txwv li, hnab looj tes, stylus), yog siv rau hauv cov xov tooj feature, lub ntiaj teb no positioning systems (GPS), printers, digital cameras, thiab cov zaub loj dua. Lawv feem ntau txhawb nqa ib tus ntiv tes kov thiab taw qhia yooj yim, thiab raug nqi tsawg dua los tsim.

Ntawm qhov tod tes, projected-capacitance touchscreens, muaj kev ua tau zoo ntawm ntau qhov kov, ua haujlwm ntev, thiab pom qhov pom tseeb, feem ntau yog siv rau hauv smartphones thiab ntsiav tshuaj. Txawm li cas los xij, qhov projected-capacitance touchscsreens tam sim no tau hloov pauv qhov kov ntawm cov khoom siv me me thiab nruab nrab, ib yam nkaus. Ntxiv mus, nce innovation nyob rau hauv qhov projected-capacitance kov, xws li kev sib koom ua ke-ups, tau tso cai rau nws ua tus nqi sib tw ntau dua thaum muaj kev sib tw tiv thaiv kev ua haujlwm.

Tus nqi lag luam

Lub ntsiab lus tseem ceeb ntawm kev tiv thaiv touchscreens yog tias lawv tsis tshua muaj nqi los tsim khoom. Txawm hais tias qhov kev ua tau zoo-kov feem ntau txwv rau qhov yooj yim-ntiv tes kov thiab taw, nws tseem ua haujlwm rau cov neeg siv dav dav. Resistive touchscreens tuaj yeem pom nyob rau hauv tsheb, kho mob, thiab cov cuab yeej siv khoom lag luam, thiab tau kawg, point-of-male (POS) terminals.

Resistive touchscreens tseem tseem ua tus thawj tswj hwm cov ntawv thov uas xav tau touchscreens ntau dua 10 ntiv tes, txij li cov nqi rau cov cuab yeej siv hluav taws xob tau nce exponentially nrog lub vijtsam loj. Tsis tas li ntawd, qee cov tuam txhab tsim khoom qub (OEMs) txuas ntxiv siv cov tshuaj tiv thaiv tiv thaiv hauv cov xov tooj, GPS, cov koob yees duab tseem ceeb, thiab cov tshuab luam ntawv nrog lub hom phiaj kom tus nqi qis hauv kev lag luam uas muaj kev sib tw loj heev.

Nyob rau hauv sib piv, projected-capacitance touchscreens muaj kev ua tau zoo nyob rau hauv qhov tseeb, lub zog noj, thiab refresh npaum li cas. Lawv kuj muaj qhov zoo tshaj plaws optical transmissivity (ntau dua 90 feem pua), uas ua rau cov duab ci dua, pom meej dua. Tsis zoo li cov tshuaj tiv thaiv tiv thaiv, qhov kev ua kom muaj peev xwm ua tau ntev, khawb-tiv taus, tsis muaj cov tsos mob laus, thiab tsis xav tau kev ntsuas.

Qhov projected capacitance tuaj yeem txhawb nqa ntau tus ntiv tes kov cov tswv yim thiab taw qhia, ua kom muaj kev txhim kho tseem ceeb rau cov neeg siv interface. Nrov gestures xws li ob tus ntiv tes pinch thiab zoom cia cov neeg siv zoom hauv lossis tawm ntawm daim duab. Nrog rau kev kov ntau, OEMs muaj peev xwm los tsim kev cai gestures, uas ntxiv tus nqi rau cov neeg siv kawg thiab tuaj yeem txhawb nqa raws li cov khoom sib txawv.
