Kodi Input Device ya Touch Screen ndi chiyani?

A touch panel ndichiwonetserozomwe zimazindikira kukhudza kwa wogwiritsa ntchito. Zonse ndi chipangizo cholowetsa (chokhudza) ndi chipangizo chotulutsa (chiwonetsero). Kudzera muzenera logwira, ogwiritsa ntchito amatha kulumikizana mwachindunji ndi chipangizochi popanda kufunikira kwa zida zachikhalidwe monga kiyibodi kapena mbewa. Zowonetsera zogwira zimagwiritsidwa ntchito kwambiri m'mafoni a m'manja, mapiritsi, ma laputopu ndi malo osiyanasiyana odzichitira okha.

Chipangizo chothandizira cha chophimba chokhudza ndi malo okhudza kukhudza, chigawo chachikulu chomwe ndi chosanjikiza chokhudza kukhudza. Malinga ndi matekinoloje osiyanasiyana, masensa okhudza amatha kugawidwa m'magulu awa:

1. Zowonetsera zosagwirizana ndi kukhudza

Zotchingira zotchingira zokanikiza zimakhala ndi zigawo zingapo, kuphatikiza zigawo ziwiri zowonda (nthawi zambiri filimu ya ITO) ndi spacer layer. Wogwiritsa ntchito akamakanikizira chinsalu ndi chala kapena cholembera, zigawo zoyendetsera zimalumikizana, ndikupanga dera lomwe limapangitsa kusintha kwapano. Wowongolera amasankha malo okhudza pozindikira malo omwe akusintha. Ubwino wa resistive touch screens ndi otsika mtengo ndi applicability zosiyanasiyana athandizira zipangizo; kuipa ndi kuti pamwamba mosavuta zikande ndi kutsika kufala kuwala.

2. Capacitive kukhudza chophimba

Capacitive touch screen imadalira mphamvu ya anthu kuti igwire ntchito. Pamwamba pa chinsalucho chimakutidwa ndi chingwe cha capacitive, pamene chala chikugwira chinsalu, chidzasintha kugawidwa kwa magetsi pamalopo, motero kusintha mphamvu ya capacitance. Wowongolera amasankha malo okhudza pozindikira malo akusintha kwa capacitance. Ma capacitive touchscreens ali ndi chidwi kwambiri, amathandizira kukhudza kwamitundu yambiri, amakhala ndi malo olimba komanso kutumizirana mwachangu, motero amagwiritsidwa ntchito kwambiri m'mafoni a m'manja ndi ma PC a piritsi. Komabe, kuipa kwake ndikuti kumafunikira malo ogwirira ntchito apamwamba, monga kufunikira kwa magolovesi abwino oyendetsa.

3. Infuraredi kukhudza chophimba

Infrared touch screen pazenera kumbali zonse za kuyika kwa infrared transmission and reception zida, mapangidwe a gridi ya infrared. Chala kapena chinthu chikakhudza chinsalu, chimatsekereza kuwala kwa infrared, ndipo sensa imazindikira malo omwe cheza cha infrared chatsekedwa kuti chizindikire malo okhudza. Infrared touch screen ndi yolimba komanso yosakhudzidwa ndi zokanda pamwamba, koma ndiyosalondola komanso imatha kusokonezedwa ndi kuwala kwakunja.

4. Surface Acoustic Wave (SAW) Kukhudza Screen

Zowonera pa Surface Acoustic Wave (SAW) zimagwiritsa ntchito ukadaulo wa akupanga, pomwe pamwamba pa chinsalucho chimakhala ndi zinthu zosanjikiza zomwe zimatha kutumiza mafunde amawu. Chala chikakhudza chinsalucho, chidzatenga mbali ya phokoso la phokoso, sensa imazindikira kuchepa kwa phokoso la phokoso, kuti mudziwe malo okhudzidwa. ku chikoka cha fumbi ndi dothi.

5. Optical Imaging Touch Panel

Optical imaging touch screen imagwiritsa ntchito kamera ndi emitter ya infrared kuti izindikire kukhudza. Kamera imayikidwa m'mphepete mwa chinsalu. Chala kapena chinthu chikakhudza chinsalu, kamera imagwira mthunzi kapena kuwonetsera kwa malo okhudza, ndipo wolamulira amasankha malo okhudza chithunzicho. Ubwino wa optical imaging touch screen ndikuti imatha kuzindikira zenera lalikulu, koma kulondola kwake komanso kuthamanga kwake ndizotsika.

6. Sonic Guided Touch Screens

Sonic guided touch screens amagwiritsa ntchito masensa kuti aziyang'anira kufalikira kwa mafunde apansi. Chala kapena chinthu chikakhudza chinsalu, chimasintha njira yofalitsa ya mafunde a phokoso, ndipo sensa imagwiritsa ntchito kusintha kumeneku kuti idziwe malo okhudza. Zowonetsera motsogozedwa ndi ma acoustic zimagwira ntchito bwino pakukhazikika komanso kulondola, koma ndizokwera mtengo kupanga.

Matekinoloje onse omwe ali pamwambawa ali ndi maubwino ake apadera komanso mawonekedwe ogwiritsira ntchito, kusankha komwe ukadaulo umatengera zosowa zenizeni zogwiritsiridwa ntchito komanso chilengedwe.
