Ukutshintsha kwe-membrane ye-backlit kulula ukuchonga nokusebenza kwindawo emnyama.Abasebenzisi banokubona ngokucacileyo indawo kunye nesimo sokutshintsha, ukuphucula ukubonakala kwemveliso ukuba ibe yisitayile kwaye yanamhlanje.Oku kunokunyusa umtsalane obonakalayo wemveliso, ukuphucula ukusebenziseka lula, kunye nokuphucula ukuchaneka komsebenzi.Ukuguquguquka koyilo lwe-backlit membrane switch ivumela ukwenziwa ngokweemfuno zoyilo lwemveliso.Uyilo lwe-backlight lunokudibaniswa kwimbonakalo yonke yemveliso ukulungelelanisa neemfuno zeendawo ezahlukeneyo, okwenza ukuba zisetyenziswe ngokubanzi kwiimveliso ezininzi.
Ukukhanyisa emva kokutshintsha kwe-membrane kufuneka kuthathelwe ingqalelo kwezi zinto zilandelayo eziphambili
Ukukhethwa komthombo wesibane sasemva:Ukuqala, kuya kufuneka ukhethe umthombo ofanelekileyo wokukhanya ngasemva.Iinketho eziqhelekileyo ziquka ukukhanya kwe-LED kunye ne-EL backlight.Ukukhanya kwe-LED ngasemva kunika izibonelelo ezinjengokukhanya okuphezulu, ubomi obude, kunye nokusebenza kakuhle kwamandla.Kwelinye icala, i-EL backlight iyaziwa ngokuba yincinci, ithambile, kunye neempawu zokukhutshwa kokukhanya okufanayo.
Uyilo olubonakalayo:Uyilo olucatshangelwe kakuhle lwe-optical luyimfuneko ukumisela indawo, inombolo, i-layout, kunye nomgama we-backlight ukusuka kumthombo wokukhanya ukuya kwi-membrane switch kunye nezinye iiparitha.Oku kuqinisekisa ukuba i-backlight inokukhanyisa ngokulinganayo yonke iphaneli yokutshintsha kwe-membrane.
Ukusetyenziswa kweepleyiti zeSikhokelo sokuKhanya:Cinga ngokufaka ipleyiti yesikhokelo esikhanyayo (efana nepleyiti yesikhokelo esikhanyayo okanye i-fiber optic) ukuncedisa ekuqondiseni ukukhanya ngokulinganayo kunye nokuphucula isiphumo sokukhanyisa ngasemva.Qinisekisa ukubekwa ngokufanelekileyo kwepleyiti yesikhokelo sokukhanya okanye ipleyiti yesibane esikhanyayo.Ukuba ufuna uncedo ekukhanyeni okukhokelela ekukhanyeni kunye nokusabalalisa ukushisa, faka ngokuchanekileyo ezi zixhobo kwindawo yokukhanya kwe-backlight yokutshintsha kwe-membrane ukuqinisekisa umphumo oqaqambileyo wokukhanya.Uyilo olukhethekileyo lwesakhiwo se-membrane switch ivumela ukuhanjiswa okufanayo kokukhanya ukusuka kumthombo we-backlight kuwo wonke umhlaba.
Ukukhethwa kwezinto:Khetha imathiriyeli efanelekileyo yokukhanya ngokusekwe kwiimfuno zoyilo ukuze kuqinisekiswe ukuhanjiswa kokukhanya, ukukhanya, kunye nokuzinza.Ukongeza, thatha ingqalelo ukuqina, ukuqhubekeka, kunye nobuhlobo bendalo bezinto ezikhethiweyo ze-backlight.
Uyilo lweSekethe:Ngexesha lenqanaba lokuqala lenkqubo yokukhanyisa, kubalulekile ukucwangcisa kunye nokuyila ukubuyisela ukukhanya ukuze kuqinisekiswe indawo, imilo, kunye neemfuno zendawo yokukhanyisa.Ukongezelela, ukuyila uxhulumaniso lwesekethe olufanelekileyo luyimfuneko ukuze kuqinisekiswe ukuba umthombo we-backlight usebenza ngokuchanekileyo kwaye ufezekise umphumo oyifunayo.Ukuphumelela kwamandla kunye nokhuseleko kufuneka kuthathelwe ingqalelo.
Uyilo lolwakhiwo lulonke:Yila ulwakhiwo lulonke lwe-membrane iswitshi, kubandakanywa ukufakwa kwesixhobo se-backlight, indlela yokulungisa, kunye neteknoloji yokucubungula.Khetha i-backlight efanelekileyo kunye nezinto ezihambelanayo ze-encapsulation ukukhusela i-backlight ukusuka kwindawo yangaphandle, ukuqinisekisa ukuqina kunye nokuhambelana kwenkqubo yokukhanya kwe-backlight kunye ne-membrane switch.
Uvavanyo kunye nokulungiswa kweempazamo:Emva kokudibanisa amacandelo okukhanyisa kunye namanye amacandelo okutshintsha kwe-membrane, uvavanyo kunye nokulungiswa kweempazamo kuya kuqhutywa ukuze kuqinisekiswe ukuba umphumo wokukhanyisa umbane uhlangabezana neemfuno zoyilo, ezifana nokukhanya okufanayo, ukucaca, njl., kunye nokuqinisekisa ukuba umphumo wokukhanyisa kunye nomsebenzi ukusebenza ngokufanelekileyo.Ukulungiswa kokugqibela kunye nokwenza ngcono kuya kwenziwa ukuba kuyimfuneko.
La manyathelo angasentla achaza inkqubo yokukhanyisa ngokubanzi kwi-membrane switch.Inkqubo ethile yokukhanyisa ingahluka ngokuxhomekeke kuyilo lwemveliso kunye nenkqubo yokuvelisa.Ngokuphumeza inkqubo yokubuyisela umva ngokucokisekileyo kunye namanyathelo okulawula umgangatho ongqongqo, kunokwenzeka ukuba kuqinisekiswe ukuba ukutshintshwa kwe-membrane kufezekise umphumo wokubuyisela umgangatho ophezulu, kunye nokuzinza nokuthembeka.
Ukutshintsha kweMembrane kunokwenziwa ngeendlela ezahlukeneyo zokukhanyisa emva, kwaye indlela efanelekileyo ikhethwa ngokusekelwe kwiimfuno zemveliso kunye neemfuno zokusebenza.Ezi zilandelayo zezinye iindlela eziqhelekileyo zokukhanyisa emva kokutshintsha kwe-membrane
Isibane se-LED ngasemva:I-LED (i-Light Emitting Diode) ukukhanya kwe-backlight yenye yezona ndlela zisetyenziswa kakhulu emva kokukhanyisa.Ukukhanyisa kwe-LED kunika izibonelelo ezifana nokusebenza kakuhle kwamandla, ubomi obude, ukufana okuphezulu okukhanyayo, kunye nokunye.Izibane ze-LED ezinemibala eyahlukeneyo zinokusetyenziswa ukwenza iziphumo ezikhanyayo zokubuyela umva.
EL (Electroluminescent) Ukukhanyisa ngasemva:Ukukhanya kwe-Electroluminescent (EL) kuthambile, kubhityile, kwaye akukho flicker-free, kuyenza ilungele ukutshintshwa kwenwebu egobileyo.I-EL backlighting ivelisa ukukhanya okufanayo kunye nokuthambileyo, kwaye isetyenziswa rhoqo kwizicelo ezifuna ukufana okuphezulu kwe-backlight.
Isibane se-CCFL (Isibane seFluorescent esibandayo seCathode) emva kokukhanyisa:Ukukhanya kwe-CCFL ngasemva kunika izibonelelo zokuqaqamba okuphezulu kunye nokuveliswa kombala okugqwesileyo, kuyenza ilungele ukutshintshwa kwenwebu ezifuna ezi mpawu.Ngaphandle kokuncipha kokuthandwa kwayo, ukukhanya kwe-CCFL ngasemva kusafumana imakethi ye-niche kwizicelo ezithile ezikhethekileyo.
Ipleyiti yesibane ngasemva:I-backlight plate inokudibaniswa nemithombo eyahlukeneyo yokukhanya (njengezibane ze-fluorescent, ii-LED, njl.) Ukufezekisa umphumo we-backlight we-membrane switch.Ubunzima kunye nezinto eziphathekayo ze-backlight plate zingakhethwa ngokusekelwe kwiimfuno zokufezekisa ukufana kunye nokukhanya kwe-backlight.
Ukukhanyisa emva kweFiber optic:I-Fiber optic guided backlighting yiteknoloji esebenzisa i-fiber optical njengento ekhokela ukukhanya ukwazisa umthombo wokukhanya ngasemva kwipaneli yokubonisa, ukuphumeza ukukhanyisa okufanayo.Itekhnoloji yokukhanyisa umva ye-Fiber optic iqhele ukusetyenziswa kwizicelo ezifuna ukukhanya okufanayo kwakhona kwiindawo ezivaliweyo, ukwakheka okuguquguqukayo, ukusebenza kakuhle kwamandla, kunye nobuhlobo bendalo.
Ukukhanya komda:Ukukhanya kwe-Edge yindlela esetyenziselwa ukufezekisa iziphumo zokukhanyisa umva ngokufaka umthombo wokukhanya kumda we-membrane yokutshintsha kunye nokusebenzisa ukukhanya kokukhanya kunye nokucamngca.Ubuchwephesha bunokukhanyisa ngokufanayo yonke indawo ye-backlit ye-membrane switch.
Ngokuxhomekeke kwiimfuno zoyilo ezahlukeneyo kunye neemfuno zokusebenza kwemveliso, unokukhetha indlela efanelekileyo yokukhanyisa umva ukuze ufezekise isiphumo esinqwenelekayo sokukhanya sokutshintsha kwenwebu.Oku kunokwandisa isibheno esibonakalayo kunye namava omsebenzisi wemveliso, ukuhlangabezana neemfuno zemarike.
