Lub ntsiab lus ntawm Shuyu Optoelectronics pob tshab electromagnetic kov tshuab! EMR yog cov ntawv luv ntawm Electro Magnetic Resonance thev naus laus zis, thiab cov ntxaij vab tshaus kov siv cov cuab yeej no tseem hu ua electromagnetic touch screens. Lub hauv paus ntsiab lus yog xa cov teeb liab electromagnetic los ntawm tus cwj mem hluav taws xob los cuam tshuam nrog electromagnetic induction board tom qab lub vijtsam. Thaum tus cwj mem hluav taws xob nyob ze rau ntawm lub vijtsam kov, lub rooj tsav xwm induction yuav hnov cov teeb liab electromagnetic ntawm tus cwj mem kom ua cov kab induction nyob rau hauv lub rooj tsavxwm electromagnetic induction. Qhov kev hloov pauv tshwm sim, thiab kab rov tav thiab ntsug antenna arrays tau txais cov cim. Electromagnetic cwj mem yog lub teeb liab transmitter thiab kav hlau txais xov array yog lub teeb liab receiver. X thiab Y ua haujlwm ntawm tus cwj mem yog xam los ntawm kev hloov pauv hauv cov hlau nplaum sib nqus.
1. Kev sib piv ntawm cov cuab yeej siv hluav taws xob tseem ceeb
Infrared: Muaj infrared emitting raj thiab infrared txais cov raj ntawm plaub sab ntawm lub vijtsam, sib xws rau kev tsim ntawm infrared matrix uas hla vertically thiab horizontally. Ib qho infrared detection net yog tsim nyob rau saum npoo ntawm lub vijtsam, thiab txhua yam khoom kov tuaj yeem hloov pauv lub infrared ntawm qhov chaw tiv tauj kom ua tiav kev ua haujlwm kov.
Qhov zoo: tsis cuam tshuam los ntawm qhov tam sim no, qhov hluav taws xob, hluav taws xob zoo li qub, tus nqi qis, kev teeb tsa yooj yim, kev ruaj ntseg zoo, kev ua haujlwm ntev, lub teeb xa hluav taws xob siab (txog 95%).
Qhov tsis zoo: Kev lag luam Hiav Txwv Liab muaj grooves thiab tsis zoo nkauj, tsis muaj plua plav los yog tsis muaj dej, thiab ntshai ntawm glare.
Capacitance: Plaub sab yog plated nrog ntev thiab nqaim electrodes, thiab ib tug tsawg-voltage AC teb yog tsim nyob rau hauv. Qhov screen yog them nrog pob tshab zaj duab xis txheej ntawm hlau conductive khoom. Thaum tus neeg siv kov lub vijtsam capacitive, tus ntiv tes thiab qhov chaw ua haujlwm yuav tsim ib qho kev sib txuas, yog li tus ntiv tes yuav nqus ib feem ntawm qhov tam sim no ntws tawm ntawm cov electrodes ntawm plaub fab ntawm lub vijtsam. Tus maub los tuaj yeem xam qhov chaw ntawm qhov chaw sib tiv tauj los ntawm kev suav cov lej ntawm cov proportions ntawm plaub tam sim no.
Qhov zoo: lub ntsej muag tiaj tus, tsis muaj dej tsis zoo thiab plua plav, tsis ntshai ntawm kev cuam tshuam glare; tus nqi lag luam siab.
Disadvantages: tus nqi siab; kuj teeb meem installation.
Electromagnetic: Kev cia siab rau ntawm qhov chaw sib nqus hloov pauv uas tsim los ntawm tus cwj mem hluav taws xob thiab lub ntsuas hluav taws xob thaum lub sijhawm ua haujlwm Txhais qhov chaw taw tes.
Qhov zoo: thawj phau ntawv sau, ob tus cwj mem thiab ob xim, lub teeb xa hluav taws xob siab thiab kev daws teeb meem, Z-axis sensing muaj peev xwm, kov tsis tau kov. High precision.
Disadvantages: tus nqi siab; yuav tsum tau koom tes nrog electromagnetic cwj mem.
