Yize kungabizi njengokubonisa noma iphaneli yesikrini sokuthinta, ukukhethwa kwesilawuli se-touchsscreen kunomthelela omkhulu ngokuya ngokusebenza kohlelo lwe-TouchScreen. Isilawuli se-TouchScreen sifaka izinzwa ze-capacitive kanye nobuchwepheshe bokuxazulula ukuxazulula ukuthinta komunwe kanye nokuthinta ngokubika indawo yabo nokuziphatha kwabo ku-processor yomgcini.
Lapho umunwe ufakwa kwisikrini sokuthinta esilinganiselwe, isilawuli sesikrini sokuthinta sithola ushintsho ku-capacitance futhi siguqule ukuthi imininingwane ibe ngamanani edijithali. Lokhu kuguqulwa kwedijithali kusetshenzwe futhi kusetshenziswa ama-algorithms we-Touch Resolution algorithms afakiwe ngaphakathi kwesilawuli sokuthintana ngaphambi kokudlula kwizixhumanisi zokuthinta kanye neminye imininingwane efanele kwiprosesa yokubamba.
Amasiginali abucayi bemisindo ayinselelo enkulu yezobuchwepheshe yama-touchscreens. Abalawuli abaqasha ama-analog asezingeni eliphakeme ngaphambili, amakhono okuphatha ngomsindo owakhelwe ngaphakathi, kanye nama-algorithms we-algorithms afakiwe aphoqelekile. Ngokuthinta iba isikhombimsebenzisi somsebenzisi sokuzikhethela kumadivayisi amaningi we-elekthronikhi yabathengi, ikhwalithi yabalawuli besikrini sokuthinta bazoba nomthelela ngqo ekuboneni komsebenzisi wokugcina. Ukukhetha isilawuli sokuthinta esilungile sokuthinta kubalulekile ekufezekiseni ukusebenza kanye nezinzuzo zezindleko.
Isilawuli esinikeza isilinganiso esiphakeme se-Signal-to-umsindo (i-SNR) nokuphathwa komsindo okusebenzayo kuzokwazi ukunxephezela ukonakaliswa kwamandla wesiginali okuvela kwimithombo yomsindo, njenge-PMMA accom lens noma isibonisi esishibhile se-accom. Ukusiza ukwenzekela ukusebenza kwezinsizwa ezibiza kakhulu neziningi, izilawuli zokuthinta kufanele zinikeze ama-algorithms ahambisanayo. Ngaphezu kwalokho, izinzuzo zezindleko ze-single-ungqimba FPC umzila zingabonakala kuphela uma i-touchscreen controller pilout ivumela ukwakheka komzila oguqukayo.
Izilawuli ze-Touchscreen zinganciphisa nezindleko zohlelo ngokusebenzisa ezinye zezici ezithuthukile abazisekelayo. Isibonelo, abalawuli abaningi bokuthinta bahumusha amanzi esikrinini sokuthinta njengokuthinta umunwe ngoba amasiginesha we-mutual capcacitance wamanzi nomunwe afanayo. Ukuxazulula le nkinga, abathengisi be-TouchScreen Panel bangangeza ungqimba olubizayo lwe-hydrophobic coating kwilensi yesembozo.
Lapho amaconsi omhlaba wamanzi ku-lens yesembozo, ukumboza kusiza ukuwaphula ngamaconsi amancane ukuze angabe esabhalisa ngokuthinta. Konke okufanayo, isilawuli se-TouchScreen esivumela ukwenqatshwa kwamanzi Ngokudabukisayo ngokusebenzisa izici zehadi yalo kanye nezimpawu ze-firmware kungabona futhi wenqabe amanzi ku-algorithms eyakhelwe ngaphakathi futhi angagcina izindleko ezengeziwe ze-coating.
