Isikrini se-capacitor sinokuqonda ulawulo lwe-touch multi-touch ngokunyusa i-electrodes ye-capacitance efanayo.Ngamafutshane, isikrini sahlulwe saba ziibhloko.Iqela leemodyuli ze-capacitance ezihambelanayo zisekwe kwindawo nganye ukuba isebenze ngokuzimeleyo, ngoko isikrini se-capacitor sinokuzibona ngokuzimeleyo ulawulo lokuthintela kwindawo nganye, kwaye emva kokucutshungulwa, ulawulo lwe-touch-touch lunokuphunyezwa ngokulula.
Iphaneli yeCapacity Touch Panel CTP (Iphaneli yeCapacity Touch) isebenza ngemvakalelo yangoku yomzimba womntu.Isikrini se-capacitor sisikrini seglasi esinemigangatho emine.Umphezulu ongaphakathi kwesikrini seglasi kunye ne-interlayer nganye ifakwe kunye ne-ITO enye (i-nano indium tin metal oxide), kunye nomgangatho ongaphandle yi-silica glass layer protective kuphela yi-0.0015mm ubukhulu.I-interlayer ITO coating isetyenziswe njengendawo yokusebenza, kwaye i-electrodes ezine zitsalwa kwiikona ezine.
Iphaneli yeprojekthi ye-capacitor
I-projective capacitive touch screen ibamba i-ITO eyahlukileyo eqhuba iimodyuli zesekethe kwii-ITO ezimbini eziqhuba iglasi.Amanani axhonywe kwiimodyuli ezimbini zi-perpendicular enye kwenye, kwaye unokucinga ngazo njengezilayidi ezitshintsha ngokuqhubekayo kwi-X kunye ne-Y.Ngenxa yokuba izakhiwo ze-X kunye ne-Y zikwindawo ehlukeneyo, i-node ye-capacitor yenziwe kwindawo yabo yokuhlangana.Esinye isilayidi sinokusetyenziswa njengomgca wokuqhuba kwaye enye njengomgca wokufumanisa.Xa i-current idluliswa ngocingo olunye kumgca wokuqhuba, ukuba umqondiso wenguqu ye-capacitance uvela ngaphandle, uya kubangela utshintsho kwi-node ye-capacitor kwenye ucingo.Utshintsho lwe-Capacitance lunokubonwa ngomlinganiselo odibeneyo we-loop ye-elektroniki, kwaye emva koko ngokusebenzisa umlawuli we-A / D uguqulelwe kwisignali yedijithali kwikhompyutheni ye-calculation processing ukufumana (X, Y) indawo ye-axis, ukuze ufezekise injongo yokubeka.
Ngethuba lokusebenza, umlawuli unika amandla kumgca wokuqhuba ngokulandelelana, okwenza indawo ethile yombane phakathi kwe-node nganye kunye nomqhubi.Emva koko, ngokuskena iilayini zezivamvo nganye nganye, utshintsho lwamandla phakathi kwee-electrode luyalinganiswa ukuze kuqatshelwe ukumiselwa kwamanqaku amaninzi.Xa umnwe okanye umnxeba we-touch medium usondela, umlawuli ufumanisa ngokukhawuleza utshintsho lwe-capacitance phakathi kwe-node yokuthintela kunye nocingo, kwaye emva koko uqinisekisa indawo yokuthintela.I-shaft enye iqhutywa luluhlu lweempawu ze-AC, kwaye impendulo kwisikrini sokuchukumisa ilinganiswa nge-electrodes kwenye i-shaft.Abasebenzisi babhekisa koku njengokuthi "traversal" induction okanye iprojection induction.Inzwa ifakwe i-X - kunye ne-Y-axis iphethini ye-ITO.Xa umnwe uchukumisa umphezulu wesikrini sokuchukumisa, ixabiso le-capacitance ngaphantsi koqhagamshelwano landa njengoko umgama phakathi kwamanqaku oqhagamshelwano ukhula.I-scan eqhubekayo kwi-sensor ibona utshintsho kwixabiso le-capacitance, kwaye i-chip yokulawula ibala amanqaku oqhagamshelwano kwaye iwabuyisele kwiprosesa.
