Iyo capacitor skrini inogona kuona yakawanda-yekubata kutonga nekuwedzera ma electrodes e mutual capacitance. Muchidimbu, skrini yakakamurwa kuita mabhuroko. Boka remutual capacitance modules rakaiswa munzvimbo yega yega kuti rishande rakazvimiririra, saka iyo capacitor skrini inogona kuzvimiririra kuona kubata kubata kwenzvimbo yega yega, uye mushure mekugadzirisa, iyo yakawanda-yekubata kutonga inogona kuitika zviri nyore.
Capacity Touch Panel CTP (Capacity Touch Panel) inoshanda nekunzwa kwazvino kwemuviri wemunhu. Iyo capacitor skrini ine mana-layer composite girazi skrini. Iyo yemukati yegirazi skrini uye interlayer imwe neimwe yakafukidzwa nerumwe rukoko rweITO (nano indium tin metal oxide), uye iyo yekunze yakatsetseka ndeye silica girazi rinodzivirira layer chete 0.0015mm gobvu. Iyo interlayer ITO coating inoshandiswa senzvimbo yekushanda, uye ma electrode mana anotorwa kubva kumakona mana.
Projective capacitor panel
Iyo projective capacitive touch screen inoisa akasiyana ITO inoitisa edunhu modules pane maviri ITO inoitisa girazi rejasi. Iwo manhamba akamisikidzwa pamamodule maviri ari perpendicular kune mumwe nemumwe, uye iwe unogona kufunga nezvawo semasiraidhi anochinja achienderera muX uye Y mafambiro. Nekuti X uye Y zvimiro zviri panzvimbo dzakasiyana, capacitor node inoumbwa pamharadzano yavo. Imwe inotsvedza inogona kushandiswa semutsetse wekutyaira uye imwe yacho seyekuona mutsara. Kana ikozvino inopfuudzwa newaya imwe pamutsara wekutyaira, kana chiratidzo che capacitance shanduko chichibva kunze, chinokonzeresa shanduko mune capacitor node pane imwe waya. Capacitance shanduko inogona kuwonekwa kuburikidza neyakasanganiswa yemagetsi loop kuyerwa, uyezve kuburikidza neA/D controller inoshandurwa kuita chiratidzo chedhijitari kumakombuta kuti calculation process iwane (X, Y) axis chinzvimbo, kuitira kuti uwane chinangwa chekuisa.
Panguva yekushanda, mutongi anopa simba kune mutsara wekutyaira, achigadzira imwe nzvimbo yemagetsi pakati penode imwe neimwe uye conductor. Zvino, nekutarisa mitsetse yekunzwa imwe neimwe, capacitance shanduko pakati pemaelectrode inoyerwa kuti ione mapoinzi akawanda. Kana chigunwe kana chigunwe chepakati chichiswedera, mutongi anokurumidza kuona shanduko ye capacitance pakati penode yekubata uye waya, uye obva asimbisa nzvimbo yekubata. Imwe shaft inotyairwa nemhando yezviratidzo zve AC, uye mhinduro iri pachiratidziri chekubata inoyerwa kuburikidza nemagetsi pane imwe shaft. Vashandisi vanotaura izvi se "kutenderera" induction kana kufungidzira induction. Iyo sensor yakaputirwa neX - uye Y-axis ITO pateni. Kana chigunwe chichibata pamusoro pechiratidziro chekubata, iyo capacitance kukosha pazasi yekubatana inowedzera sezvo chinhambwe pakati pematanho ekusangana chinowedzera. Iyo inoenderera mberi scan pane sensor inoona shanduko ye capacitance values, uye iyo control chip inoverenga mapoinzi ekusangana uye inoadzosera kune processor.
