Isikrini se-capacitor singakwazi ukulawula ukuthinta okuningi ngokwandisa ama-electrodes of capacitance mutual. Ngamafuphi, isikrini sihlukaniswe ngamabhulokhi. Iqembu lamamojula we-mutual capacitance asethwe endaweni ngayinye ukuze asebenze ngokuzimela, ngakho-ke isikrini se-capacitor singakwazi ukubona ngokuzimela ukulawulwa kokuthinta kwendawo ngayinye, futhi ngemva kokucubungula, ukulawula okuthinta okuningi kungenziwa kalula.
I-Capacity Touch Panel CTP (Capacity Touch Panel) isebenza ngokuzwa kwamanje komzimba womuntu. Isikrini se-capacitor siyingilazi enezingqimba ezine eziyinhlanganisela yesikrini. Indawo engaphakathi yesikrini sengilazi kanye ne-interlayer ngayinye imbozwe ngongqimba olulodwa lwe-ITO (i-nano indium tin metal oxide), kanti ungqimba olungaphandle luwugqinsi lwengilazi ye-silica evikelayo kuphela engu-0.0015mm. I-interlayer ITO coating isetshenziswa njengendawo yokusebenza, futhi ama-electrode amane adonswa emagumbini amane.
Iphaneli ye-projective capacitor
Isikrini sokuthinta esibonakalayo se-capacitive sihlanganisa amamojula we-ITO ahlukene aqhuba isekethe kuma-ITO amabili aqhuba izingilazi zengilazi. Izibalo eziqoshwe kumamojula amabili zincikene, futhi ungacabanga ngazo njengezilayidi ezishintsha ngokuqhubekayo ku-X no-Y. Ngenxa yokuthi izakhiwo ze-X kanye no-Y zisendaweni ehlukene, kwakheka i-capacitor node ezimpambanweni zazo. Isilayidi esisodwa singasetshenziswa njengomugqa wedrayivu kanti esinye njengolayini wokuthola. Uma i-current idluliswa ngocingo olulodwa emgqeni wokushayela, uma isignali yokuguqulwa kwe-capacitance ivela ngaphandle, izobangela ushintsho ku-node ye-capacitor kwenye intambo. Izinguquko zamandla zingatholwa ngesilinganiso se-loop ye-elekthronikhi exhunyiwe, bese ngesilawuli se-A/D siguqulelwe kusignali yedijithali kukhompuyutha ukuze kucutshungulwe izibalo ukuze kutholwe (X, Y) indawo ye-eksisi, ukuze kufezwe injongo yokuma.
Ngesikhathi sokusebenza, isilawuli sinikeza amandla kumugqa wokushayela ngokushintshana, sakha inkambu ethile kagesi phakathi kwe-node ngayinye kanye nomqhubi. Bese, ngokuskena imigqa yezinzwa ngayinye ngayinye, izinguquko ze-capacitance phakathi kwama-electrode ziyalinganiswa ukuze kubonakale ukuma kwamaphuzu amaningi. Lapho umunwe noma i-touch medium isondela, isilawuli sibona ngokushesha ushintsho lwe-capacitance phakathi kwenodi yokuthinta nocingo, bese siqinisekisa indawo yokuthinta. I-shaft eyodwa ishayelwa amasiginali e-AC, futhi impendulo kusikrini sokuthinta ikalwa ngama-electrode kwenye shaft. Abasebenzisi babiza lokhu njengokuthi "traversal" induction noma ukuqaliswa kokuqagela. Inzwa ihlanganiswe nephethini ye-ITO engu-X - kanye ne-Y-axis. Lapho umunwe uthinta ubuso besikrini esithintwayo, inani le-capacitance ngaphansi kokuxhumana liyakhula njengoba ibanga phakathi kwamaphoyinti okuxhumana likhula. Ukuskena okuqhubekayo kunzwa kuthola izinguquko kumanani we-capacitance, futhi isilawuli chip sibala amaphoyinti okuxhumana futhi iwabuyisele kumprosesa.
