Lub vijtsam capacitivite kov tau yog lub cuab yeej tso tawm cov vijtsam uas muaj kev sib cuam tshuam ntawm cov ntiv tes. Capacitive kov cov khoom siv hluav taws xob feem ntau yog sib txuas, thiab cov khoos phis tawj, khawm kov ntau yam, cov ntsiav tshuaj satellite thiab xov tooj ntawm tes
Lub peev xwm kev tshuaj ntsuam kov tau tshuab los ntawm tib neeg kov, uas tau txais cov hluav taws xob siv los txhawb cov tshuab hluav taws xob ntawm lub vijtsam kov. Tsis zoo li kov yeej, qee qhov kev sib tw tsis tuaj yeem siv los kuaj cov ntiv tes los ntawm cov hnab looj tes hluav taws xob, xws li hnab looj tes. Qhov kev tsis zoo no feem ntau cuam tshuam rau kev siv tau hauv cov khoom siv hluav taws xob, xws li kov cov ntsiav tshuaj PCs thiab carthophritive hauv huab cua txias thaum tib neeg yuav hnav hnab looj tes. Nws tuaj yeem kov yeej nrog cov hnab looj tes tshwj xeeb stylus, lossis cov hnab looj tes tshwj xeeb nrog cov xov paj ntawm cov xov hluav taws xob tso cai rau cov neeg siv ntiv tes.
Peev xwm cov ntxaij vab tshaus tau ua rau hauv cov cuab yeej tawm tswv yim, suav nrog kov cov neeg molitooters, txhua-hauv-ib lub khoos phis tawj, smartphones thiab cov ntsiav tshuaj PCs.
Lub peev xwm tshuaj ntsuam tau tsim nrog insulator-zoo li iav txheej, uas yog them nrog tus neeg tshaj tawm, xws li indium tin oxide (ito). Lub ITO txuas nrog khob phaj uas compress ua kua muaju hauv lub kov npo. Tus Neeg Siv Kev Ua Haujlwm Txhaj Tshuaj Hluav Taws Xob ua kom tsim kev them nqi hluav taws xob, uas ua rau cov roj ua kua crystal.
Capacitive kov screen hom yog raws li nram no:
Deg capactance: coated ntawm ib sab nrog me volage coj ua khaubncaws sab nraud. Nws muaj kev daws teeb meem tsawg thiab feem ntau siv hauv kiosks.
Projected capacitiviting kov (PCT): siv etched conductive txheej nrog electrode cov qauv sib dhos. Nws tau muaj kev muaj zog architecture thiab feem ntau siv nyob rau hauv kev sib tw ntawm kev muag khoom.
PT Mutual Capacitance: Lub catacitor yog nyob rau txhua qhov kev sib tshuam ntawm kev thov voltage. Nws pab txhawb multitouch.
PCT tus kheej lub peev xwm: kab thiab cov kab lis haujlwm muaj tus kheej ntawm cov metres tam sim no. Nws muaj lub cim muaj zog dua pct kev sib nrig Confensance thiab cov haujlwm zoo nrog ib tus ntiv tes.
