Kov-hauv-ib lub tshuab luam ntawv yog hom kev tshaj tawm tshuab luam ntawv, uas yog siv rau hauv ntau qhov chaw, yog li koj puas paub qhov kev faib tawm ntawm kov-hauv-ib lub tshuab luam ntawv?
1. Resistive kov tag nrho-hauv-ib qhokev tshaj tawm tshuab
Siv qhov ntsuas siab los tswj.Qhov tseem ceeb ntawm lub tshuab kov kov tag nrho-hauv-ib qho yog lub vijtsam tiv thaiv zaj duab xis uas haum zoo nrog lub ntsej muag ntawm cov zaub.Qhov no yog ib tug multi-layer composite zaj duab xis.Nws siv lub iav los yog tawv yas phaj raws li lub hauv paus txheej, thiab saum npoo yog coated nrog ib txheej ntawm pob tshab oxide hlau (pob tshab Conductive resistance) conductive txheej, them nrog ib tug hardened txheej txheej, du thiab anti-scratch yas txheej, nws puab. nto kuj yog coated nrog ib txheej ntawm txheej, muaj ntau me me (tsawg dua 1/1000 nti) nruab nrab ntawm lawv Lub pob tshab cais taw tes cais ob txheej conductive rau rwb thaiv tsev.Thaum tus ntiv tes kov lub vijtsam, ob txheej txheej txheej yog nyob rau hauv kev sib cuag ntawm qhov taw tes kov, qhov kev hloov pauv, cov teeb liab raug tsim nyob rau hauv X thiab Y cov lus qhia, thiab tom qab ntawd xa mus rau qhov kov npo tswj.Tus maub los kuaj xyuas qhov kev sib cuag no thiab xam qhov chaw ntawm (X, Y), thiab tom qab ntawd ua haujlwm raws li kev simulating nas.Qhov no yog lub hauv paus ntsiab lus tseem ceeb tshaj plaws ntawm resistive technology kov cov ntxaij vab tshaus.
2. Capacitive kov tag nrho-hauv-ibkev tshaj tawm tshuab
Ua haujlwm siv qhov tam sim no induction ntawm tib neeg lub cev.Lub capacitive touch screen yog plaub-txheej txheej iav npo.Lub puab nto thiab interlayer ntawm lub iav screen yog txhua coated nrog ib txheej ntawm ITO.Cov txheej txheej sab nrauv yog txheej nyias ntawm silica iav tiv thaiv txheej.Lub interlayer ITO txheej yog siv los ua qhov chaw ua haujlwm ntawm plaub fab.Lead tawm plaub lub electrodes, txheej sab hauv ntawm ITO yog ib txheej thaiv los xyuas kom meej qhov chaw ua haujlwm zoo.Thaum tus ntiv tes kov cov txheej hlau, vim yog lub zog hluav taws xob ntawm tib neeg lub cev, lub coupling capacitor yog tsim los ntawm tus neeg siv thiab qhov chaw ntawm lub vijtsam kov.Rau high-frequency tam sim no, lub capacitor yog tus neeg xyuas pib ncaj qha, yog li tus ntiv tes rub tawm me me tam sim no los ntawm qhov chaw sib cuag.Qhov tam sim no ntws los ntawm cov electrodes ntawm plaub lub ces kaum ntawm lub vijtsam kov, thiab tam sim no ntws los ntawm plaub lub electrodes yog proportional rau qhov kev ncua deb ntawm tus ntiv tes mus rau plaub lub ces kaum.Tus maub los tau txais txoj hauj lwm ntawm qhov taw tes kov los ntawm kev xam qhov sib piv ntawm plaub qhov tam sim no.
3. Infrared kov tag nrho-hauv-ib lub tshuab
Lub tshuab hluav taws xob infrared kov npo yog tsim los ntawm infrared emitting thiab tau txais cov ntsiab lus sensing mounted rau sab nrauv ntawm lub vijtsam kov.Nyob rau saum npoo ntawm qhov screen, ib qho infrared detection net yog tsim.Txhua yam khoom kov tuaj yeem hloov cov duab hluav taws xob infrared ntawm cov neeg sib cuag kom paub txog kev ua haujlwm ntawm lub vijtsam kov.Lub hauv paus ntsiab lus ntawm infrared kov screen yog zoo ib yam li cov nto acoustic yoj kov, nws siv infrared kis thiab tau txais cov ntsiab lus sensing.
Cov ntsiab lus no tsim ib qho kev tshawb nrhiav infrared nyob rau saum npoo ntawm lub tshuab kov txhua-hauv-ib qho.Cov khoom siv kov (xws li cov ntiv tes) tuaj yeem hloov pauv cov duab hluav taws xob infrared ntawm cov hluav taws xob poob siab, uas tom qab ntawd hloov mus rau hauv qhov chaw sib koom tes ntawm qhov kov kom paub txog cov lus teb ntawm kev ua haujlwm.Ntawm lub vijtsam infrared kov, cov khoom siv hluav taws xob hauv Circuit Court tau teeb tsa ntawm plaub sab ntawm lub vijtsam muaj infrared emitting hlab thiab infrared txais cov raj, sib xws rau kev tsim cov kab rov tav thiab ntsug cross infrared matrix.
