Kodi pali zowonera zamtundu wanji?

Malinga ndi mtundu wa sensa, touchscreen imagawidwa m'mitundu inayi: mtundu wa infrared, resistive mtundu, mawonekedwe amtundu wamayimbidwe am'mwamba ndi chophimba cha capacitive.
Ubwino ndi kuipa kwa zowonera zinayi zogwira:
1.The infrared technology touch screen ndi yotsika mtengo, koma chimango chake chakunja ndi chosalimba, chosavuta kutulutsa kusokoneza kwa kuwala, ndipo chimasokonekera pakakhala malo opindika;
2.The capacitive luso kukhudza chophimba ali wololera kamangidwe lingaliro, koma fano kupotoza vuto ndi zovuta kwenikweni kuthetsa;
3.Kuyika kwa chophimba chokhudza ukadaulo wotsutsa ndikolondola, koma mtengo wake ndi wokwera kwambiri, ndipo ukuwopa kukanda ndikuwonongeka;
4.Pamwamba pa ma acoustic wave touch screen amathetsa zolakwika zosiyanasiyana zomwe zidachitika kale.Ndizomveka komanso zosavuta kuonongeka.Ndi oyenera nthawi zosiyanasiyana.
Chojambula chojambula cha infrared chili ndi chimango cha boardboard kutsogolo kwa chiwonetserocho, ndipo bolodi yozungulira imakonzedwa ndi machubu otulutsa ma infrared ndi machubu olandila ma infrared mbali zinayi za chinsalu, ndikupanga masanjidwe opingasa komanso ofukula a infrared mu gawo limodzi. -makalata amodzi.

Wogwiritsa ntchito akakhudza chinsalu, chala chidzatsekereza kuwala kopingasa komanso kowongoka komwe kumadutsa pamalowo, kotero kuti malo okhudza pazenera angadziwike.

Chilichonse chokhudza chimatha kusintha cheza cha infrared pa touch point kuti izindikire kugwira ntchito kwa skrini.

Chotchinga cha infrared touchcho sichimakhudzidwa ndi magetsi apano, ma voliyumu ndi ma static, ndipo ndi oyenera pazovuta zina zachilengedwe.

Ubwino wake waukulu ndi mtengo wotsika, kukhazikitsa kosavuta, palibe makhadi kapena owongolera ena, ndipo angagwiritsidwe ntchito pamakompyuta amitundu yosiyanasiyana.

Kuonjezera apo, popeza palibe capacitor kulipiritsa ndi kutulutsa ndondomeko, liwiro la yankho liri mofulumira kuposa la capacitive capacitive, koma chisankhocho ndi chochepa.

Mbali yakunja ya chophimba chotsutsa nthawi zambiri imakhala chophimba chofewa, ndipo zolumikizira zamkati zimalumikizidwa mmwamba ndi pansi ndikukanikiza.Wosanjikiza wamkati amakhala ndi zitsulo zakuthupi za oxide oxide, ndiye kuti, N-mtundu wa oxide semiconductor - indium tin oxide (Indium Tin Oxides, ITO), yomwe imatchedwanso indium oxide, yokhala ndi kuwala kwa 80%.ITO ndiye chinthu chachikulu chomwe chimagwiritsidwa ntchito pazowonera zonse za resistive touch ndi capacitive touch screen.Malo awo ogwirira ntchito ndi zokutira za ITO.Akanikizire wosanjikiza akunja ndi nsonga zala kapena chinthu chilichonse, kuti pamwamba filimu ndi concavely olumala, kotero kuti zigawo ziwiri zamkati za ITO kugundana ndi kuchititsa magetsi udindo.Kwa ma coordinates a pokanikizira kuti muzindikire kuwongolera.Malinga ndi kuchuluka kwa mizere yotsogolera pazenera, pali 4-waya, 5-waya ndi mawaya angapo, malire ndi otsika, mtengo wake ndi wotsika mtengo, ndipo mwayi ndikuti sukhudzidwa ndi fumbi, kutentha ndi chinyezi.Kuipa kulinso koonekeratu.Kanema wakunja amakanda mosavuta, ndipo zinthu zakuthwa sizingagwiritsidwe ntchito kukhudza chophimba.Nthawi zambiri, kukhudza kosiyanasiyana sikutheka, ndiko kuti, mfundo imodzi yokha ndiyomwe imathandizidwa.Ngati olumikizana awiri kapena kupitilira apo akanikizidwa nthawi imodzi, zolumikizira zolondola sizingadziwike ndikupezeka.Kuti mukulitse chithunzi pa zenera loletsa, mutha kungodina "+" kangapo kuti mukulitse chithunzicho.Iyi ndiye mfundo yoyambira yaukadaulo ya chophimba chotsutsa.

Kuwongolera pogwiritsa ntchito kupanikizika kwa mphamvu.Chala chikakhudza chinsalu, zigawo ziwiri za conductive zimagwirizana pa touch point, ndipo kukana kumasintha.

Zizindikiro zimapangidwa munjira zonse za X ndi Y kenako zimatumizidwa ku chowongolera chophimba.

Woyang'anira amazindikira kulumikizidwa uku ndikuwerengera malo (X, Y), ndiyeno amachita mogwirizanag ku njira yofananira ndi mbewa.

The resistive touch screen siwopa fumbi, madzi ndi dothi, ndipo imatha kugwira ntchito m'malo ovuta.

Komabe, chifukwa chakuti mawonekedwe akunja a filimu yophatikizika amapangidwa ndi zinthu zapulasitiki, kukana kuphulika kumakhala kosauka, ndipo moyo wautumiki umakhudzidwa pamlingo wina.

The resistive touch screen imayang'aniridwa ndi kukakamizidwa.Pamwamba pake ndi pulasitiki, ndipo pansi pake ndi galasi, lomwe lingathe kupirira kusokonezeka kwa zinthu zoopsa za chilengedwe, koma limakhala ndi vuto losamva bwino lamanja komanso kufalitsa kuwala.Ndikoyenera kuvala magolovesi ndi omwe sangathe kukhudza mwachindunji ndi manjachochitika.

Surface acoustic mafunde ndi mafunde opangidwa ndi makina omwe amafalikira pamwamba pa sing'anga.

M'ngodya za kukhudza chophimba ali okonzeka ndi akupanga transducers.

Phokoso lamphamvu kwambiri limatha kutumizidwa padziko lonse lapansi.Chala chikakhudza chinsalu, phokoso la phokoso pa malo okhudzidwa limatsekedwa, potero limazindikira malo ogwirizanitsa.

Pamwamba pamayimbidwe amawonekedwe touch screen samakhudzidwa ndi zinthu zachilengedwe monga kutentha ndi chinyezi.Ili ndi kusamvana kwakukulu, kukana zikande, moyo wautali, kufalikira kwapamwamba, ndipo imatha kukhalabe ndi chithunzi chowoneka bwino komanso chowala.Ndizoyenera kwambiri kugwiritsidwa ntchito m'malo opezeka anthu ambiri.

Komabe, fumbi, madzi ndi dothi zidzakhudza kwambiri ntchito yake ndipo zimafunika kukonza pafupipafupi kuti chinsalu chikhale choyera.

4.Capacitive touch screen
Mtundu uwu wa touch screen umagwiritsa ntchito kulowetsedwa kwa thupi la munthu kuti agwire ntchito.A wosanjikiza mandala zitsulo conductive zakuthupi amaikidwa pa galasi pamwamba.Pamene chinthu conductive kukhudza, capacitance wa kukhudzana adzasinthidwa, kotero kuti malo kukhudza akhoza wapezeka.
Koma palibe kuyankha pamene kukhudzidwa ndi dzanja la gloves kapena kugwira chinthu chosayendetsa chifukwa cha kuwonjezera kwa sing'anga yowonjezera.
Capacitive touch screen imatha kuzindikira kuwala komanso kukhudza mwachangu, anti-scratch, osawopa fumbi, madzi ndi dothi, zoyenera kugwiritsidwa ntchito m'malo ovuta.
Komabe, popeza capacitance imasiyanasiyana ndi kutentha, chinyezi kapena malo amagetsi achilengedwe, imakhala yosakhazikika, yosasunthika, ndipo ndiyosavuta kusuntha.
