Touch Screen yog dab tsi?

Raws li cov cuab yeej tawm tswv yim tshiab, lub vijtsam kov tam sim no yog qhov yooj yim tshaj plaws, yooj yim thiab ntuj txoj hauv kev ntawm tib neeg-lub computer kev sib cuam tshuam.

Kov npo, tseem hu ua "kov vaj huam sib luag", yog ib qho inductive LCD zaub ntaus ntawv uas tuaj yeem tau txais cov cim taw qhia; Thaum kov cov graphical nyees khawm ntawm lub vijtsam, lub haptic tawm tswv yim rau ntawm lub vijtsam tuaj yeem tsav ntau yam kev sib txuas ntawm cov khoom siv raws li qhov kev pab cuam ua ntej, uas tuaj yeem siv los hloov lub vaj huam sib luag khawm khawm, thiab tsim kom muaj lub suab thiab video cuam tshuam los ntawm lub LCD zaub screen, nws lub ntsiab daim ntawv thov teb yog lub xov tooj ntawm tes, ntsiav tshuaj computers, nyiaj ntsuab registers, industrial teb, thiab lwm yam.

Muaj ntau ntau hom kov cov ntxaij vab tshaus nyob rau hauv kev ua lag luam: resistive, nto capacitive thiab inductive capacitive kov cov ntxaij vab tshaus, nto acoustic yoj, infrared, raws li zoo raws li nkhaus yoj, active digital converter thiab optical imaging touch screens. Ib qho tuaj yeem muab faib ua ob pawg, ib qho xav tau ITO, xws li thawj peb lub vijtsam kov, thiab lwm yam tsis xav tau ITO hauv cov qauv, xws li tom qab ob peb lub vijtsam. Tam sim no, kov cov ntxaij vab tshaus thiab capacitive kov cov ntxaij vab tshaus siv cov ntaub ntawv ITO yog cov khoom siv dav tshaj plaws hauv kev ua lag luam.

Cov qauv ntawm lub vijtsam kov feem ntau yog tsim los ntawm peb ntu: ob txheej ntawm cov pob tshab tiv thaiv hluav taws xob, ib txheej cais ntawm ob txheej ntawm cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob.

Resistive conductor txheej: Lub substrate sab sauv yog yas, qis substrate yog iav, thiab cov hluav taws xob conductive indium tin oxide (ITO) yog coated rau ntawm lub substrate los ua ob ITO txheej, sib cais los ntawm ib co cais fulcrum txog ib txhiab ntawm ib nti tuab.

Electrode: Kev xaiv cov khoom siv hluav taws xob zoo heev (xws li tus lej nyiaj), nws qhov kev ua tau zoo yog kwv yees li 1000 npaug ntawm ITO.

Kev rho tawm txheej: Kev siv cov yeeb yaj kiab polyester nyias nyias PET, thaum qhov saum npoo yog kov nws yuav khoov, thiab ua rau ob txheej ITO txheej hauv qab no tuaj yeem tiv tauj ib leeg, txhawm rau txuas lub voj voog, uas yog vim li cas qhov kov. screen tuaj yeem ua tiav tus yuam sij rau kov.
