Qhov Tseeb Txhim Kho Hauv PCAP Touch Screen Technology

Qhov Tseeb Txhim Kho Hauv PCAP Touch Screen Technology

Hauv qab no peb tham txog qee yam ntawm cov yam ntxwv uas ua kom cov thev naus laus zis no kov yeej cov kev cov nyom yav dhau los.

1. Kov Controller

Hauv PCAP Kov npo, muaj ob txoj kev daws teeb meem tseem ceeb rau kov npo tswj, nti ntawm lub rooj tsavxwm (COB) thiab nti ntawm FPC (COF).

Chip ntawm lub rooj tsavxwm (COB), nws yog ua kom cov nti thiab lwm yam khoom siv ncaj qha rau ntawm ib lub rooj tsavxwm PCB. Nws tso cai rau lub teeb liab kis tau los ntawm qhov kov sensor mus rau PCB los ntawm kev hloov pauv hloov pauv. Tom qab ntawd, IC firmware hloov cov ntaub ntawv capacitance rau hauv cov ntaub ntawv kov digital, thiab xa mus rau tus tswv tsev. Rau qhov loj dua, feem ntau yuav siv cov tshuaj COB.

Chip ntawm FPC (COF), nws yog ua kom cov nti thiab lwm yam khoom siv ncaj qha rau ntawm qhov hloov tau yooj yim. Nyob rau hauv cov ntaub ntawv no, lub analog capacitance teeb liab yog hloov dua siab tshiab rau digital txoj hauj lwm cov ntaub ntawv ntawm FPC, thiab serial interface yuav xa cov ntaub ntawv mus rau lub computer. Yog tias koj xav siv lub vijtsam kov me me, ces peb xav kom koj xaiv qhov kev daws teeb meem no, uas yog tus nqi zoo.

2. Suab nrov tiv thaiv

Electromagnetic cuam tshuam (EMI) suab nrov tuaj yeem cuam tshuam nrog kev tshawb pom tseeb ntawm cov xwm txheej kov hauv PCAP kov npo. Yog tias koj cov khoom siv ib puag ncig xav tau kev tiv thaiv lub suab nrov, ces thaum xaiv cov tshuaj nti, koj yuav tsum xaiv cov tshuaj uas muaj suab nrov tiv thaiv. Yog tias koj tseem xav tias qhov kev tiv thaiv suab nrov tsis zoo nyob rau theem tom ntej, koj tuaj yeem ua kom zoo dua los ntawm firmware.

3. Kev kho dej

Hauv qee cov khoom siv tshwj xeeb, tej zaum yuav muaj ib puag ncig nrog dej ntawm lub vijtsam kov, xws li los nag sab nraum zoov. Dej los nag yuav ua rau muaj teeb meem kov tsis tseeb. Txhawm rau zam cov teeb meem no, koj tuaj yeem xaiv lub nti daws teeb meem uas txhawb nqa dej kov, lossis ua rau txheej txheej tiv thaiv tus ntiv tes rau saum npoo ntawm lub vijtsam kov. Vim tias lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm dej kov yog qhov zoo ib yam li cov qauv kev ua haujlwm ntawm peb cov neeg kov lub vijtsam kov. Yog li ntawd, ua ib txheej ntawm cov tshuaj tiv thaiv tus ntiv tes rau saum npoo kuj yog ib qho teeb meem los tiv thaiv dej los ntawm kev ua yuam kev.

4. Kov nrog hnab looj tes

PCAP Touch Screen kuj tuaj yeem txhawb nqa qhov kov ntawm cov hnab looj tes sib txawv. Piv txwv li, hauv kev tswj hwm kev lag luam lossis cov khoom siv kho mob, cov khoom siv no yuav xav tau lub vijtsam kov tuaj yeem txhawb nqa nrog hnab looj tes. Yog tias koj xav txhawb kov nrog cov hnab looj tes, koj tuaj yeem ua ntej raws li cov tuab thiab cov khoom siv ntawm koj cov hnab looj tes. Peb tuaj yeem phim koj nrog cov kev daws teeb meem zoo tshaj plaws.
