Waliwo ebika bya tekinologiya wa touch screen bisatu:
Resistive: Ekipande kya touch screen ekiziyiza kisiigibwako ekyuma ekigonvu eky’amasannyalaze ekitambuza amasannyalaze n’ekiziyiza ekivaako enkyukakyuka mu masanyalaze agawandiisibwa ng’ekintu ekikwata ku kukwata era ne kisindikibwa eri ekifuga okulongoosebwa. Resistive touch screen panels okutwalira awamu zibeera za bbeeyi naye ziwa 75% zokka okutegeera era layer esobola okwonooneka ebintu ebisongovu. Resistive touch screen panels tezikosebwa bintu bya bweru nga enfuufu oba amazzi.
Surface Wave: Tekinologiya w’amayengo ag’okungulu akozesa amayengo ga ultrasonic agayita ku kipande kya touch screen. Ekipande bwe kikwatibwako, ekitundu ky’amayengo kinywezebwa. Enkyukakyuka eno mu ultrasonic waves ewandiisa ekifo ky’ekintu ekikwata ku kukwata era esindika amawulire gano eri controller okukola. Surface Wave touch screen panels ze zisinga okubeera ez’omulembe mu bika ebisatu, naye zisobola okwonooneka olw’ebintu eby’ebweru.
Capacitive: Ekipande kya capacitive touch screen kisiigibwako ekintu ekitereka amasannyalaze. Ekipande bwe kikwatibwako, akasannyalazo akatono kakubwa okutuuka ku ssa ly’okukwatagana. Circuits ezisangibwa ku buli nsonda ya panel zipima charge era ziweereza amawulire eri controller okukola. Capacitive touch screen panels zirina okukwatibwako n’engalo okwawukana ku resistive ne surface wave panels ezisobola okukozesa engalo ne .Stylus .. Capacitive touch screens tezikosebwa bintu bya bweru era zirina okutegeera okungi.
