Chophimba cha mawaya anayi chili ndi zigawo ziwiri zotsutsa.Chigawo chimodzi chimakhala ndi basi yoyimirira kumanzere ndi kumanja kwa chinsalu, ndipo china chimakhala ndi basi yopingasa pansi ndi pamwamba pa chinsalu, monga momwe tawonetsera pa Chithunzi 1.
Chithunzi 1 The voliyumu divider amazindikirika polumikiza resistors awiri mndandanda [6]
Yezerani mbali ya X-axis, kondera basi yakumanzere kupita ku 0V, ndi basi yakumanja kupita ku VREF.Lumikizani basi pamwamba kapena pansi ku ADC, ndipo muyeso ukhoza kupangidwa pamene zigawo zapamwamba ndi zapansi zikugwirizana.
Chithunzi 2 Magawo awiri olimbana ndi mawaya anayi
Pofuna kuyeza kolowera ku Y-axis, mabasi apamwamba amakondera ku VREF ndipo basi yapansi ndiyokondera ku 0V.Lumikizani cholowera cha ADC kubasi yakumanzere kapena basi yakumanja, ndipo voteji imatha kuyeza pomwe gawo lapamwamba likhudzana ndi gawo la pansi.Chithunzi 2 chikuwonetsa chosavuta chojambula chazithunzi zolumikizira mawaya anayi pamene zigawo ziwirizo zikukhudzana.Pa zenera la mawaya anayi, njira yabwino yolumikizira ndi kulumikiza basi mokondera ku VREF kugawo lolowera ku ADC, ndikulumikiza basi yokhazikitsidwa ku 0V kugawo lolowera ku ADC.
Voltage divider imadziwika polumikiza ma resistor awiri motsatizana
Awiri resistive zigawo zinayi mawaya touch screen
Chotchinga chokhudza mawaya asanu
Sewero la mawaya asanu limagwiritsa ntchito wosanjikiza wosanjikiza ndi wosanjikiza conductive.The conductive layer imakhala ndi cholumikizira, nthawi zambiri m'mphepete mwake mbali imodzi.Pali kukhudzana pa iliyonse ya ngodya zinayi za wosanjikiza wosanjikiza.Kuti muyese momwe mungayendere X-axis, sinthani ngodya zakumanzere ndi kumanzere kupita ku VREF, ndipo ngodya zakumanja ndi zapansi kumanja zimakhazikika.Popeza ngodya za kumanzere ndi kumanja zimakhala ndi magetsi omwewo, zotsatira zake zimakhala zofanana ndi basi yomwe imagwirizanitsa kumanzere ndi kumanja, mofanana ndi njira yomwe imagwiritsidwa ntchito pazithunzi zazitsulo zinayi.Kuti muyese motsatira mzere wa Y, ngodya yakumanzere yakumanzere ndi ngodya yakumanja imatsitsidwa ku VREF, ndipo ngodya yakumanzere yakumanzere ndi ngodya yakumanja yakumanja imatsitsidwa ku 0V.Popeza ngodya zam'mwamba ndi zam'munsi zili pamagetsi omwewo, zotsatira zake zimakhala zofanana ndi basi yomwe imagwirizanitsa m'mphepete mwa pamwamba ndi pansi, mofanana ndi njira yomwe imagwiritsidwa ntchito pazithunzi zazitsulo zinayi.Ubwino wa aligorivimu muyeso ndi kuti amasunga voteji kumtunda kumanzere ndi m'munsi kumanja ngodya zosasinthika;koma ngati makonzedwe a gridi agwiritsidwa ntchito, ma ax X ndi Y ayenera kusinthidwa.Pa zenera la mawaya asanu, njira yabwino yolumikizira ndikulumikiza ngodya yakumanzere yakumanzere (yokondera ngati VREF) kugawo lolowera la ADC, ndikulumikiza ngodya yakumanzere yakumanzere (yokondera ku 0V) kunjira yolakwika. gawo la ADC.
Gawo lapansi lagalasi ndi chinthu chofunikira kwambiri popanga TFT-LCD, ndipo mtengo wake umakhala pafupifupi 15% mpaka 18% ya mtengo wonse wa TFT-LCD.Idapangidwa kuchokera pamzera woyamba (300mm × 400mm) mpaka mzere wazaka khumi (2,850mm × 3,050).mm), yangodutsa nthawi yochepa ya zaka makumi awiri.Komabe, chifukwa cha zofunikira kwambiri pakupanga mankhwala, kagwiridwe ka ntchito ndi kapangidwe ka magawo agalasi a TFT-LCD, ukadaulo wapadziko lonse lapansi wapadziko lonse lapansi wa TFT-LCD waukadaulo wopanga magalasi ndi msika wakhala akugwiritsidwa ntchito ndi Corning ku United States, Asahi Glass ndi Galasi yamagetsi, etc. Monopolized ndi makampani ochepa.Pansi pa kukwezeleza kwakukulu kwa chitukuko cha msika, dziko la dziko langa linayambanso kutenga nawo mbali mu R & D ndi kupanga magawo a galasi a TFT-LCD mu 2007. Pakalipano, mizere yambiri ya TFT-LCD yopanga magalasi a m'badwo wachisanu ndi pamwamba amangidwa ku China.Iwo akukonzekera kukhazikitsa awiri 8.5-m'badwo mkulu-m'badwo wamadzimadzi galasi galasi gawo lapansi kupanga mzere ntchito mzere mu theka lachiwiri la 2011. Izi zimapereka chitsimikizo chofunika kwa kumasulira kwa kumtunda kwa zipangizo zopangira TFT-LCD opanga kumtunda kwa dziko langa ndi yofunika kwambiri. kuchepetsa ndalama zopangira.
Seven-waya touch screen
Njira yogwiritsira ntchito mawonekedwe azithunzi zisanu ndi ziwiri ndizofanana ndi chophimba chazitsulo zisanu kupatulapo kuti mzere umodzi umawonjezedwa kumtunda kumanzere ndi kumunsi kumanja.Mukamayesa zenera, lumikizani waya wina kukona yakumanzere kumanzere ku VREF, ndipo waya wina ku terminal yolozera ya SAR ADC.Nthawi yomweyo, waya wina pakona yakumanja yakumanja amalumikizidwa ndi 0V, ndipo waya winayo amalumikizidwa ku terminal yolondolera ya SAR ADC.The conductive layer imagwiritsidwabe ntchito kuyeza voteji ya voltage divider.
Eyiti-waya touch screen
Pokhapokha kuwonjezera waya umodzi pa basi iliyonse, njira yokhazikitsira mawonekedwe a sewero la mawaya asanu ndi atatu ndi yofanana ndi mawonekedwe a mawaya anayi.Kwa basi ya VREF, waya umodzi umagwiritsidwa ntchito kulumikiza ku VREF, ndipo waya wina umagwiritsidwa ntchito ngati njira yabwino yosinthira digito-to-analogi ya SAR ADC.Pabasi ya 0V, waya umodzi umagwiritsidwa ntchito kulumikiza ku 0V, ndipo waya wina umagwiritsidwa ntchito ngati cholozera cholakwika cha chosinthira cha digito-to-analogi cha SAR ADC.Imodzi mwa mawaya anayi omwe ali pamtunda wosakondera angagwiritsidwe ntchito kuyeza voteji ya voliyumu yamagetsi.
