Capacitive touch screens ziwa ekitangaala ekisinga obulungi obutambuzibwa n’okutegeera okusinga 4-Wire resistive screens, era mazima ddala si nnungi nga surface acoustic ne five-ssirini za waya eziziyiza.
Ekisenge kya capacitive kirina okufumiitiriza okw’amaanyi. Ate era, tekinologiya ow’ekimpatiira (capacitive technology) ya ssirini ennya (four-layer composite touch screen) tekwatagana mu buweerero bw’ekitangaala obwa buli wavelength, era waliwo ekizibu ky’okukyusakyusa langi. Olw’okuba ekitangaala kyeyolekera wakati wa layers, ekifaananyi ky’abantu kijja kuba kifuuse kifuuse.
Current: Enkola ya capacitive screen eri nti omubiri gw’omuntu gukozesa electrode nga electrode element. Kondakita bw’aba kumpi ne ffeesi y’omuguwa (interlayer iTo working face) ne capacitance emala eyongerwako, okukulukuta kw’amasannyalaze kumala okuleeta ekikolwa ekikyamu eky’olutimbe lwa capacitive.
Newankubadde nga capacitance egerageranya mu ngeri ey’ekifuulannenge n’ebanga wakati w’ebikondo, egerageranye n’ekitundu ekikwatagana era nayo ekwatagana n’omugerageranyo gwa dielectric.
N’olwekyo, bwe kiba nti ennukuta ennene-ekitundu oba kondakita ow’omu ngalo eri kumpi n’olutimbe lwa capacitive era nga tesobola kukwatibwako, kijja kuleeta ekikolwa ekikyamu eky’olutimbe lwa capacitive. Mu mbeera y’obudde erimu obunnyogovu, embeera eno ya maanyi nnyo. Fuselage y’okulaga mu ngalo, ng’engalo eri kumpi ne monitor sentimita 7 oba okumpi ne monitor 15 cm, eyinza okuleeta ekikolwa ekikyamu eky’olutimbe lwa capacitive.
Ekizibu ekirala ekiri mu ssirini za capacitive kwe kuba nti tezikola nga zikwatibwako oba nga zikwatibwa omukono ogulina ggalavu olw’ekintu ekiziyiza okugatta.
Drift: Ekizibu ekikulu ekiri mu ssirini ya capacitor ye Drift: Ebbugumu ly’obutonde, obunnyogovu n’amasannyalaze bwe bikyuka, kijja kuleeta okuwuguka kwa ssirini ya capacitor, ekivaako obutatuukirira.
Okugeza, ebbugumu lya monitor lijja kulinnya oluvannyuma lwa boot okujja okuleeta okuwuguka: omukozesa akwata ku screen, ate omukono omulala okumpi ne monitor oba oludda lw’omubiri gujja kuwuguka;
Ebintu ebinene mu kitundu ekiriraanye capacitive touch screen bijja kuwuguka, era singa omukozesa abikwatako era omuntu ali okumpi n’alaba, era kijja kuleeta okuwuguka.
Capacitive Screen Drift ye nfumo y'ebyekikugu, .
Wadde ng’ebitundu ebiyinza okubaawo (nga mw’otwalidde n’omubiri gw’omukozesa) biri wala nnyo okuva ku ssirini ya capacitive touch screen, biba binene nnyo okusinga ekitundu ky’engalo, era bikosa butereevu okupima ekifo ky’okukwata.
Many others: in addition, the theory should be A linear relationship is actually nonlinear, such as different weight or wet finger levels of total power flow is different, and the change of the total current and the change of the four independent flow is nonlinear relationship, in the corners of the custom pole coordinate system is used in capacitive touch screen without origin of coordinates, drift controller cannot be detected and recovered, 4, after the completion of A/d calculation process of the x, Y coordinates of four points to Omuwendo gw’ensonga z’okukwatako mu nkola ya Cartesian coordinate guzibu.
Olw’okuba tewali nsibuko, capacitive screen drift ekuŋŋaanyizibwa era etera okwetaaga okupimibwa ku kifo ky’emirimu.
Endabirwamu ezikuuma silicon dioxide ku ludda olw’ebweru olwa capacitive touch screen erina okuziyiza okulungi ennyo, naye etya emisumaali oba ebintu ebikalu, ekiyinza okwonoona sandwich ya ITO. Ka kibeere nga kifunye obuvune era nga kikoleddwa mu laminated, oba nga kisiiga layeri ya ITO ku ngulu w’omunda mu kiseera ky’okussaako n’okutambuza, ekisenge kya capacitive tekijja kukola bulungi.
