Iphaneli yeTouch, ekwabizwa ngokuba yi "touch screen" kunye "touch panel", sisixhobo sokubonisa ikristale engamanzi esebenzayo esinokufumana imiqondiso yegalelo njengabafowunelwa.
Inkqubo yempendulo ye-haptic inokuqhuba izixhobo ezahlukeneyo zokunxibelelanisa ngokweenkqubo ezicwangciswe kwangaphambili, ezinokuthi zisetyenziswe ukutshintsha indawo yepaneli yeqhosha lomatshini, kwaye yenze iziphumo ezicacileyo zeaudio-visual nge-liquid crystal display screen.
Izinto eziluncedo kunye nokungalunganga kweZikrini ezine zokuTofa Njengesixhobo esitsha sokufaka ikhompyutha, isikrini sokuchukumisa siyindlela elula, efanelekileyo kunye neyendalo yokusebenzisana komntu nekhompyuter.
Inika imultimedia inkangeleko entsha kwaye sisixhobo esitsha esinomtsalane semultimedia.
Isetyenziswa kakhulu kumbuzo wolwazi loluntu, ulawulo lwamashishini, umyalelo womkhosi, imidlalo yevidiyo, ukufundisa ngemultimedia, njl.
Ngokohlobo lwenzwa, isikrini sokuchukumisa sahlulahlulwe ngokweendidi ezine: uhlobo lwe-infrared, uhlobo lokumelana, uhlobo lwamaza omgangatho we-acoustic kunye ne-capacitive touch screen.
Izinto ezilungileyo kunye nokungalunganga kwezikrini ezine zokuchukumisa:
1.I-infrared technology touch screen inexabiso eliphantsi, kodwa isakhelo saso sangaphandle siethe-ethe, kulula ukuvelisa ukuphazamiseka kokukhanya, kwaye sigqwethiwe kwimeko yeendawo ezigobileyo;
2.I-capacitive technology touch screen inombono woyilo olufanelekileyo, kodwa ingxaki yokuguqula umfanekiso wayo kunzima ukuyisombulula;
3.Ukubekwa kweteknoloji yokuthintela isikrini sokuchukumisa ichanekile, kodwa ixabiso layo liphezulu kakhulu, kwaye iyoyika ukukrwelwa kwaye yonakaliswe;
4.Umphezulu we-acoustic wave touch screen usombulula iziphene ezahlukeneyo zesikrini sokuchukumisa sangaphambili.Kucacile kwaye akukho lula ukonakala.Ifanelekile kwiimeko ezahlukeneyo.
Isikrini se-infrared touch screen sixhotyiswe ngesakhelo sebhodi yesekethe phambi komboniso, kwaye ibhodi yesekethe icwangciswe ngeetyhubhu zokukhutshwa kwe-infrared kunye neetyhubhu zokufumana i-infrared kumacala amane esikrini, zenza i-matrix ethe tye kunye nethe nkqo ye-infrared kwindawo enye ukuya. -enye imbalelwano.
Xa umsebenzisi echukumisa isikrini, umnwe uya kuvala imitha ye-infrared ethe tyaba kunye nethe nkqo edlula kwindawo, ngoko ke indawo yokuchukumisa isikrini inokumiselwa.
Nayiphi na into yokuchukumisa inokutshintsha imitha ye-infrared kwindawo yokucofa ukuze iqonde ukusebenza kwesikrini sokuchukumisa.
Isikrini esichukumisayo se-infrared asikhuselekanga kumbane wangoku, umbane kunye nombane omileyo, kwaye ulungele iimeko ezithile eziqatha zokusingqongileyo.
Iinzuzo zayo eziphambili lixabiso eliphantsi, ukufakwa lula, akukho makhadi okanye naziphi na ezinye izilawuli, kwaye zinokusetyenziswa kwiikhomputha zamabanga ahlukeneyo.
Ukongezelela, ekubeni akukho ntlawulo ye-capacitor kunye nenkqubo yokukhupha, isantya sokuphendula sikhawuleza kunohlobo lwe-capacitive, kodwa isisombululo siphantsi.
Umaleko ongaphandle wesikrini esichasayo ngokuqhelekileyo sisikrini esithambileyo, kwaye abafowunelwa bangaphakathi badityaniswa phezulu naphantsi ngokucinezela.Umaleko wangaphakathi uxhotyiswe ngezinto eziphathekayo ze-oxide yensimbi, oko kukuthi, i-N-type oxide semiconductor - i-indium tin oxide (i-Indium Tin Oxides, i-ITO), ebizwa ngokuba yi-indium oxide, ene-transmittance yokukhanya kwe-80%.I-ITO yeyona nto isetyenziswayo kuzo zombini izikrini zokuthintela kunye ne-capacitive touch screens.Umphezulu wabo osebenzayo yingubo ye-ITO.Cinezela umaleko wangaphandle ngeencam zeminwe okanye nayiphi na into, ukuze ifilimu yomphezulu ikhubazeke, ukuze amaleko amabini angaphakathi e-ITO angqubane kwaye aqhube umbane wokubeka indawo.Kulungelelaniso lwendawo yocinezelo ukuqonda ulawulo.Ngokwenani lemigca ekhokelayo yesikrini, kukho i-4-wire, i-5-wire kunye ne-multi-wire, i-threshold iphantsi, ixabiso lincinci, kwaye inzuzo kukuba ayichatshazelwa luthuli; ubushushu kunye nokufuma.Ingxaki nayo iyabonakala.Ifilimu yesikrini sangaphandle ikrwelwa ngokulula, kwaye izinto ezibukhali azinakusetyenziselwa ukuchukumisa umphezulu wesikrini.Ngokuqhelekileyo, i-multi-touch ayinakwenzeka, oko kukuthi, inqaku elinye kuphela elixhaswayo.Ukuba abafowunelwa ababini okanye ngaphezulu bacinezelwe ngexesha elinye, ulungelelwaniso oluchanekileyo alunakubonwa kwaye lufunyanwe.Ukwandisa umfanekiso kwiscreen esichasayo, unokucofa kuphela u-"+" amaxesha amaninzi ukwandisa umfanekiso.Lo ngumgaqo osisiseko wobugcisa wesikrini esichasayo.
Ukulawula usebenzisa i-pressure sensing.Xa umnwe uchukumisa isikrini, iileyile ezimbini zokuqhuba zidibanisa kwindawo yokuchukumisa, kwaye ukuchasana kuyatshintsha.
Iimpawu zenziwa kuzo zozibini izikhombisi ze-X kunye ne-Y kwaye emva koko zithunyelwa kwisilawuli sesikrini sokuchukumisa.
Umlawuli ubhaqa lomfowunelwa kwaye abale i (X, Y) indawo, aze aziphathe ngokungqinelanag kwindlela yokulinganisa impuku.
Isikrini sokuthintela esichasayo asiloyiki uthuli, amanzi kunye nokungcola, kwaye sinokusebenza kwiindawo ezinzima.
Nangona kunjalo, ngenxa yokuba umgca wangaphandle wefilimu edibeneyo yenziwe ngezinto zeplastiki, ukuxhatshazwa kokuqhuma kubi, kwaye ubomi benkonzo buchaphazeleka kwinqanaba elithile.
Isikrini sokuchukumisa esithintelayo silawulwa yimvakalelo yoxinzelelo.Umaleko wayo ongaphezulu ngumaleko weplastiki, kwaye umaleko ongezantsi ngumaleko weglasi, onokumelana nokuphazamiseka kwezinto ezirhabaxa zokusingqongileyo, kodwa unesandla esibi kunye nokuhanjiswa kokukhanya.Kufanelekile ukugqoka iiglavu kunye nezo zingenakuchukunyiswa ngokuthe ngqo ngezandlaithuba.
Amaza e-acoustic angaphezulu ngamaza anomatshini asasaza kumphezulu wesiphakathi.
Iikona zesikrini sokuchukumisa zixhotyiswe nge-ultrasonic transducers.
Izandi zesandi esinezandi eziphezulu zinokuthunyelwa ngaphaya komphezulu wesikrini.Xa umnwe uchukumisa isikrini, i-wave yesandi kwindawo yokuchukumisa ivaliwe, ngaloo ndlela imisela indawo yokulungelelanisa.
Umphezulu we-acoustic wave screen awuchatshazelwa yimiba yokusingqongileyo efana nobushushu kunye nokufuma.Inesisombululo esiphezulu, ukumelana nokukrweleka, ubomi obude, ukuhanjiswa kokukhanya okuphezulu, kwaye inokugcina umgangatho womfanekiso ocacileyo noqaqambileyo.Yeyona ilungele ukusetyenziswa kwiindawo zikawonke-wonke.
Nangona kunjalo, uthuli, amanzi kunye nokungcola kuya kuchaphazela kakhulu ukusebenza kwayo kwaye kufuna ukulungiswa rhoqo ukugcina isikrini sicocekile.
4.Capacitive touch screen
Olu hlobo lwesikrini sokuchukumisa lusebenzisa ukungeniswa kwangoku komzimba womntu ukuba usebenze.Umaleko ocacileyo wezinto ezikhethekileyo zetsimbi zincanyathiselwe kumphezulu weglasi.Xa into eqhubayo ichukumisa, i-capacitance yomfowunelwa iya kutshintshwa, ukwenzela ukuba indawo yokuchukumisa ingabonwa.
Kodwa akukho mpendulo xa uchukunyiswa ngesandla seglavu okanye ubambe into engekho conductive ngenxa yokongezwa kwe-insulating medium.
I-Capacitive touch screen inokubona ukukhanya kunye nokuchukumisa ngokukhawuleza kakuhle, i-anti-scratch, ingoyiki uthuli, amanzi kunye nokungcola, ilungele ukusetyenziswa kwiindawo ezinzima.
Nangona kunjalo, ekubeni i-capacitance ihluka ngeqondo lokushisa, ukufuma okanye indawo yombane yokusingqongileyo, inozinzo olubi, isisombululo esiphantsi, kwaye kulula ukukhukuliseka.
