ukadaulo wa nfrared touch screen umapangidwa ndi ma infrared emitting ndi kulandira zinthu zomverera zomwe zimayikidwa pazithunzi zakunja kwa chophimba chokhudza. Pamwamba pazenera, netiweki yozindikira infrared imapangidwa. Chilichonse chokhudza chikhoza kusintha mawonekedwe a infuraredi pamalo olumikizirana kuti azindikire kugwira ntchito kwa skrini. Mfundo yogwiritsiridwa ntchito kwa infrared touch screen ndi yofanana ndi yapamtunda wamayimbidwe kukhudza. Imagwiritsa ntchito ma infrared emitting ndi kulandira ma sensor. Zinthu izi zimapanga netiweki yozindikira ma infrared pamwamba pa chinsalu. Chinthu chogwira ntchito (monga chala) chingasinthe infuraredi ya malo okhudzana, omwe amasinthidwa kukhala malo ogwirizanitsa a kukhudza kuti azindikire kuyankha kwa ntchitoyo. Pa zenera la infrared touch screen, zida za board board zomwe zakonzedwa mbali zinayi za chinsaluzo zimakhala ndi machubu otulutsa ma infrared ndi machubu olandila ma infrared, omwe amapanga matrix opingasa komanso opindika.
Infrared touch screen ndi infrared matrix yomwe imagawidwa kwambiri munjira za X ndi Y kutsogolo kwa chinsalu. Imazindikira ndikuzindikira kukhudza kwa wogwiritsa ntchito poyang'ana mosalekeza ngati cheza cha infuraredi chatsekedwa ndi zinthu. Monga tawonera pachithunzichi "Working Principle of Infrared Touch Screen", chophimba ichi chimayikidwa ndi chimango chakunja kutsogolo kwa chiwonetserocho. Chimango chakunja chimapangidwa ndi bolodi ladera, kuti machubu otumizira ma infuraredi ndi machubu olandila amakonzedwa pambali inayi ya chinsalu, chimodzi ndi chimodzi chogwirizana kuti apange masanjidwewo opingasa ndi ofukula mtanda wa infuraredi. Pambuyo pa sikani iliyonse, ngati machubu onse a infrared alumikizidwa, kuwala kobiriwira kumayaka, kuwonetsa kuti zonse nzabwinobwino.
Pakakhala kukhudza, chala kapena chinthu china chimatsekereza kuwala kopingasa komanso koyima kwa infuraredi komwe kumadutsa pamalopo. Pamene chojambula chojambula chikayang'ana ndikupeza ndikutsimikizira kuti kuwala kwa infrared kwatsekedwa, kuwala kofiira kudzakhala kuyatsa, kusonyeza kuti cheza cha infrared chatsekedwa ndipo pangakhale kukhudza. Panthawi imodzimodziyo, idzasintha nthawi yomweyo ku mgwirizano wina ndikujambulanso. Zikapezeka kuti nsonga ina ilinso ndi cheza cha infrared chotsekedwa, kuwala kwachikasu kudzakhala kuyatsa, kusonyeza kuti kukhudza kwapezeka, ndipo malo a machubu awiri a infrared omwe apezeka kuti atsekedwa adzadziwitsidwa kwa mwiniwakeyo. Pambuyo kuwerengera, malo a touch point pa zenera anatsimikiza.
Zogulitsa za infrared touch screen zimagawidwa m'mitundu iwiri: zakunja ndi zamkati. Kuyika njira ya mtundu wakunja ndikosavuta kwambiri ndipo ndikosavuta kwambiri pakati pa zowonera zonse. Ingogwiritsani ntchito guluu kapena tepi ya mbali ziwiri kukonza chimango kutsogolo kwa chiwonetserocho. Chojambula chojambula chakunja chingathenso kukhazikitsidwa pawonetsero ndi mbedza, yomwe ili yabwino kwa disassembly popanda kusiya zizindikiro zilizonse.
Mawonekedwe aukadaulo a infrared touch screen:
1. Kukhazikika kwakukulu, osagwedezeka chifukwa cha kusintha kwa nthawi ndi chilengedwe
2. Kusinthasintha kwapamwamba, kosakhudzidwa ndi magetsi apano, magetsi ndi static, oyenera pazovuta zina za chilengedwe (zosaphulika, zowonongeka ndi fumbi)
3. Kutumiza kowala kwambiri popanda sing'anga yapakatikati, mpaka 100%
4. Moyo wautali wautumiki, kukhazikika kwakukulu, osawopa zipsera, moyo wautali wautali
5. Makhalidwe abwino ogwiritsira ntchito, palibe chifukwa chokakamiza kukhudza, palibe zofunikira zapadera za thupi lokhudza
6. Imathandizira ma point 2 oyerekeza pansi pa XP, imathandizira mfundo ziwiri zowona pansi pa WIN7,
7. Imathandizira USB ndi serial port output,
8. Kusamvana ndi 4096 (W) * 4096 (D)
9. Good opaleshoni dongosolo ngakhale Win2000/XP/98ME/NT/VISTA/X86/LINUX/Win7
10. Kukhudza m'mimba mwake ＞= 5mm
Kuchokera pamlingo wogwiritsa ntchito, chophimba chokhudza sichiyenera kukhala chida chosavuta chomwe chimasinthira kukhudza kukhala chidziwitso cholumikizana, koma chiyenera kupangidwa ngati mawonekedwe athunthu amakina amunthu. Chiwonetsero chachisanu cha m'badwo wachisanu cha infrared touch screen chimachokera pamiyezo yotereyi, ndipo chimazindikira kusintha kwa malingaliro azinthu kudzera mu mapurosesa omangidwa ndi mapulogalamu abwino oyendetsa.
Choncho, teknoloji yatsopano ya infrared touch idzakhudza kwambiri msika wapakhomo ndi wakunja.
