Lub capacitive touch screen yog lub cuab yeej tso saib lub vijtsam uas tso siab rau cov ntiv tes siab rau kev sib cuam tshuam.Capacitive touch screen li feem ntau yog tuav, thiab txuas mus rau tes hauj lwm lossis khoos phis tawj ntawm kev tsim qauv uas txhawb nqa ntau yam khoom, suav nrog kev lag luam kov saib, POS them nyiaj tshuab, kov kiosks, satellite navigation li, ntsiav tshuaj PCs thiab xov tooj ntawm tes.
Lub capacitive kov npo yog qhib los ntawm tib neeg kov, uas ua haujlwm raws li cov khoom siv hluav taws xob siv los txhawb cov electrostatic teb ntawm lub vijtsam kov.Tsis zoo li cov tshuaj tiv thaiv tiv thaiv, qee qhov capacitive touchscreens tsis tuaj yeem siv los ntes tus ntiv tes los ntawm cov khoom siv hluav taws xob, xws li hnab looj tes.Qhov tsis zoo no tshwj xeeb tshaj yog cuam tshuam rau kev siv tau hauv cov neeg siv khoom siv hluav taws xob, xws li kov cov ntsiav tshuaj PCs thiab cov xov tooj smartphones capacitive thaum huab cua txias thaum tib neeg yuav hnav hnab looj tes.Nws tuaj yeem kov yeej nrog ib qho tshwj xeeb capacitive stylus, los yog ib lub hnab looj tes tshwj xeeb nrog rau ib qho embroidered thaj ntawm conductive xov tso cai rau hluav taws xob tiv tauj nrog tus neeg siv lub ntsis ntiv tes.
Capacitive kov cov ntxaij vab tshaus tau tsim rau hauv cov khoom siv nkag, suav nrog cov saib xyuas, txhua lub khoos phis tawj, smartphones thiab ntsiav tshuaj PCs.
Lub capacitive kov npo yog tsim nrog cov txheej txheem zoo li iav, uas yog them nrog tus neeg xyuas pib, xws li indium tin oxide (ITO).Lub ITO yog txuas rau iav daim hlau uas compress cov kua siv lead ua kua hauv lub vijtsam kov.Tus neeg siv tshuaj ntsuam ua kom tsim hluav taws xob, uas ua rau cov kua siv lead ua kua.
Capacitive touch screen hom yog raws li nram no:
Surface Capacitance: Coated ntawm ib sab nrog me me voltage conductive txheej.Nws muaj kev daws teeb meem tsawg thiab feem ntau siv hauv kiosks.
Projected Capacitive Touch (PCT): Siv etched conductive txheej nrog electrode grid qauv.Nws muaj cov qauv tsim muaj zog thiab feem ntau siv hauv kev muag khoom muag.
PCT Mutual Capacitance: Lub capacitor yog nyob ntawm txhua qhov kev sib tshuam ntawm daim phiaj siv hluav taws xob.Nws yooj yim multitouch.
PCT Self Capacitance: Cov kab thiab kab ua haujlwm ntawm tus kheej ntawm cov ntsuas tam sim no.Nws muaj lub teeb liab muaj zog dua li PCT kev sib nrig sib capacitance thiab ua haujlwm zoo nrog ib tus ntiv tes.
