I inzwa yokulinganisa ocingweni - kuyini? Amaselula

Isethi kwemikhiqizo yesimanje electronics ifakwe izinzwa ukuqaphela indlela bento, isib, umunwe, ikhibhodi noma endlebeni yomuntu ifoni. Lobu buchwepheshe kabanzi lisetshenziswe touch panel ezihlukahlukene, okwenza kungabi usuke imishini futhi baphile isikhathi eside yabo yenkonzo. Futhi abaningi bangase kahle ucelwe: inzwa ukusondela ocingweni - kuyini futhi asebenze kanjani? kule divayisi kuzoxoxwa ngemuva kwalokhu ngokuya kokusebenza ku ubuchwepheshe capacitive.

ukuqashelwa indlela

Recognition isilinganiselo yokuxhumana ngobuchwepheshe yashesha isicelo emkhakheni amadivayisi ephathekayo inikwa amandla yi ngokuzimela. Umsebenzi kabanzi lisetshenziswe izindlela zakamuva of Smartphones kanye amaphilisi, e abadlali umculo. Inhloso Its main iwukuba ukwandisa ukuthembeka amadivayisi bese ulondoloza amandla kagesi.

Isibonisi iyunithi uzokhishwa nje indlela itholwa isandla yomsebenzisi, it unesibopho ke kanye inzwa yokulinganisa efonini yakho. Kuyini - kuyokhanya uma sicabanga isimiso emsebenzini wayo. Uma kuziwa ukusetshenziswa kwalo buchwepheshe, lapha ke Kuyaphawuleka ukuthi esikhathini eceleni amandla imodi ukusetshenziswa ukwenza kuphela wokugaya emaphakathi. Lapho izinzwa ukusondela ukucacisa lapho kusondela entendeni noma umunwe, isibonisi esithile sisebenza esitshalweni, elibonisa ulwazi lwamanje. Konke lokhu kunciphisa isilinganiso amandla ukusetshenziswa igajethi, kube kwandziswa sokusebenza ibhethri.

Izici ukusetshenziswa kwemisebenzi amasu ahlukahlukene

I sasekhaya esienzekelayo ukutholwa kwebanga sici futhi wathola isakazeke kabanzi. Izinzwa Indawo engalapho asetshenziselwa unike amandla izibani etafuleni, valve kokuvula Washer, lapho emkhakheni wabo isinyathelo isandla womuntu; isibonisi amafriji kanye microwave Ohhavini uyobe engakwazi kwenza lutho kuze kube abayikusondela esandleni yomsebenzisi. Ziphethe lo msebenzi, futhi entsha uhlelo sasekhaya esienzekelayo. Thinta Izikrini, esetshenziswa ukulawula zasendlini kanye ukukhanyisa, usethe ukuba ngikhonze njengephayona Uhlaka isithombe sedijithali. Kodwa ngokushesha nje lapho useduze abanye abantu ngokushesha avele zokulawula. Enough ubuchwepheshe ezithakazelisayo inzwaduze efonini yakho. Lokho kuyinto kuyasiza ukuqonda incazelo ndlela ukuqashelwa senzeka.

izindlela Ukuthola i approximating

Kukhona izindlela eziningi, phakathi okuyinto exhasa, resistive, optical, capacitive, optical futhi acoustical. Ngamunye wabo kunezinzuzo ezithile kanye nobubi obuthile. Kukhethwa ubuchwepheshe incike izindleko futhi kalula ukusebenza naso. Cabanga inzwaduze ocingweni - kuyokusiza ukuba baqonde ulwazi oluthile. Ezimweni eziningi, le capacitive ukusondela izinzwa asetshenziswa. Isimiso wokusebenza ulula. Inzwa babashayeli kanye nalokho ofanele, kufihlwe ngaphansi ungqimba ekhethekile zokuzivikela. Amabili kokuqhuba isici iseduze nomunye, abe capacitance ezithile ehlangeni okuyinto kuphakama phakathi ungqimba conductive futhi isisekelo pad we inzwa uqobo. Ngokuvamile imali salo 10-300 pikafarad.

Lapho inzwa siyasondela, isibonelo, umunwe, ushintsho jikelele amandla uhlelo. Isetshenziselwa ukuthola into eduze inzwa non-contact.

Ukuthola capacitance ushintsho

Vele kanjani nalikhuluma ngemlandvo futsi letsembekile non-contact inzwa izosebenza, lithembela ngokuphelele nesilinganiso zibonise ukwethembeka besikhundla esishintshile ohlelweni. Ukuze kufezwe lokho, ke itfutfukise izindlela, kuhlanganise eyaziwa kakhulu izindlela steel icala ukudluliswa, isilinganiselo ngokulandelana nokuxhumana isitsha futhi indlela sigma-delta. Ngokuvamile asetshenziswa bobabili. Bobabili usebenzise esitshalweni capacitance wesifunda kanye yangaphandle wokulinganisa capacitor.

Indlela ziwukulinganisela ngokulandelana

Kulokhu, ukukhokhiswa wenziwa a esitshalweni capacitor wesifunda. Njengoba voltage capacitor lisetshenzisiwe comparator ngokusebenzisa ongaphakeme pass lemifanekiso, lapho eqhathaniswa inkomba voltage. Esiphikisayo, clocked ngu generator, ikhiyiwe esebenzisa isignali comparator okukhiphayo. Ukucubungula le isignali Kwenziwa ngoba isimo esithile inzwa. inombolo azinakwa izingxenye yangaphandle iyadingeka ukuze indlela ziwukulinganisela ngokulandelana. Kulokhu, ukusebenza wesifunda akuphazamisi crosstalk at supply chain.

Ngebuhle nebubi ukuqashelwa ubuchwepheshe

Inzwa i-Android, njengabanye, has izici ezithile. Izinzuzo kulokhu zimi kanje:

- ngempela indawo ukuthola;

- ngezinga eliphezulu lokutfutfukako;

- ukutholakala isihlobo ngokuya amanani, ngoba ukukhiqizwa izinzwa yizici ngempela ezishibhile - ithusi, ithini oxide ifilimu, ink indium, yangaphandle wire inzwa;

- Usayizi Small;

- sikwazi ukwenza izinto ezihlukahlukene umklamo;

- lokushisa ukuzinza;

- ikhono bahlinza ezahlukene enamathela non-conductive, isibonelo, ingilazi ugqinsi ezahlukene;

- ukuqina kanye enokwethenjelwa.

Kukhona le ndlela has bokwenza ezithile:

- element abathola ukuba conductive, khona-ke uyokwazi ukubona indlela; kodwa isandla, isibonelo, a igilavu iraba, futhi akakwazi ukuthola;

- ekutholeni eduze into conductive kungadala ukuba le ndlela recalculate capacitance yisinanakazana ukuze kubhekelelwe izinguquko ezidalwa into. Lokhu ngokuvamile kuba imbangela ukuhlatshwa komkhosi oyiphutha Nokho, esikhathini esizayo, lo Samandla inzwa yokulinganisa uzoqeda lesi inkathazo;

- capacitive ukuthola indlela usebenza ukuze uma uhla umsebenzi wakhe, kukhona sufaka uhla sinciphile.

Khiya iPhone 4 isikrini

Inzwaduze usebenza ukuze ikuvumela ukukhubaza esikrinini smartphone ngesikhathi socingo ukuze Ukuvimbela ukucindezeleka ngephutha kwezinkinobho. Kukhona izinhlelo zokusebenza ezikhethekile ezenza kungenzeka yokukhiya isikrini ngokumane ngokuswayipha phezu kwalo ngesandla. Ukuze uyinike amandla, kudingeka ucindezele inkinobho hardware.

Ukulinganiswa

Kaningi, abasebenzisi ibhekene esimweni esingajabulisi, lapho yokuvala isikrini uma ukhuluma akuyona kwenziwe. Futhi kwenzeka ukuthi isibonisi ingavuli ngemva ikholi isiqedile, yingakho ifoni akakavuli. Ngokwesibonelo, Nokia inzwa yokulinganisa ayisebenzi kahle. Ukuxazulula lenkinga, kufanele ulinganiswe. Ngokuvamile, abakhiqizi abaningi basebenzisa isofthiwe ezikhethekile le njongo, okuyinto ingalandwa ku website esemthethweni.

Izinguqulo zakamuva ze-Android 4, umsebenzi Samandla okuhlanganiswe kwimenyu. Ukuze wenze lokhu, kudingeka ungene ku izilungiselelo, funa isikrini, bese ukhetha Inzwa yokulinganisa Samandla. Ngemva kokuvala inzwa ingalo kumele ibe ewindini elivelayo, uqhebeza OK. Ngezinye izikhathi avunyelwe Samandla futhi ngaphandle Ukuvalwa inzwa.
