1. I-engeli yokubuka
I-angle yokubuka yesibonisi se-LED incike engeli lokubuka lamalambu e-LED. Okwamanje, iningiisibonisi se-LED sangaphandlefuthiizikrini zokubonisa ze-LED zangaphakathi sebenzisa ama-SMD LED ane-engeli yokubuka evundlile neqondile engu-140°. Izibonisi ze-LED zesakhiwo eside zidinga ama-engeli aphakeme wokubuka aqondile. I-engeli yokubuka nokukhanya kuyaphikisana, futhi i-engeli yokubuka enkulu nakanjani izokwehlisa ukukhanya. Ukukhethwa kwe-engeli yokubuka kudinga ukunqunywa ngokuya ngokusetshenziswa okuqondile.
2. Ukukhanya
Ukukhanya kobuhlalu besibani se-LED kuyisici esibalulekile sokukhanya kwesibonisi se-LED. Uma iphezulu ukukhanya kwe-LED, kuba mkhulu umkhawulo wamanje osetshenziswayo, okulungele ukonga ukusetshenziswa kwamandla nokugcina i-LED izinzile. Ama-LED anamanani ahlukene e-engeli. Uma ukukhanya kwe-chip kulungisiwe, i-engeli encane, i-LED ikhanya kakhulu, kodwa iba yincane i-engeli yokubuka yesibonisi. Ngokuvamile, i-LED engu-120-degree kufanele ikhethwe ukuze kuqinisekiswe i-engeli yokubuka eyanele yesibonisi. Ngezibonisi ezinamachashazi ahlukene namabanga wokubuka ahlukene, iphoyinti lebhalansi kufanele litholakale ngokukhanya, i-engeli namanani.
3. Izinga lokwehluleka
Kusukelaisibonisi se-LED esinombala ogcwele yakhiwe amashumi ezinkulungwane noma amakhulu ezinkulungwane zamaphikseli ahlanganiswe ama-LED abomvu, aluhlaza naluhlaza, ukwehluleka kwanoma yimuphi umbala we-LED kuzothinta umphumela wokubonwayo wawo wonke isibonisi se-LED. Ngokuvamile, izinga lokuhluleka kwesibonisi se-LED akufanele libe ngaphezu kuka-3/10,000 ngaphambi kokuthi isibonisi se-LED siqale ukuqoqwa futhi siguge amahora angu-72 ngaphambi kokuthunyelwa.
4. Ikhono le-Antistatic
I-LED iyisisetshenziswa se-semiconductor, ezwela kugesi omile futhi ingaholela kalula ekuhlulekeni kukagesi omile. Ngakho-ke, ikhono le-anti-static libaluleke kakhulu empilweni yesikrini sokubonisa. Ngokuvamile, i-voltage yokuhluleka yokuhlolwa kwemodi ye-electrostatic ye-LED yomzimba womuntu akufanele ibe ngaphansi kuka-2000V.
5. Ukungaguquguquki
Isikrini sokubonisa se-LED esinemibala egcwele yakhiwe ngamaphikseli akhiwe ama-LED amaningi abomvu, aluhlaza, naluhlaza. Ukuvumelana kokukhanya nobude begagasi bombala ngamunye we-LED inquma ukuvumelana kokukhanya, ukungaguquguquki kwebhalansi emhlophe, nokuvumelana kwechromaticity kwaso sonke isikrini sokubonisa.
Isibonisi se-LED esinemibala egcwele sinokuqondiswa kwe-angular, okungukuthi, ukukhanya kwaso kuzokhuphuka noma kunciphe uma sibukwa ngama-engeli ahlukene. Ngale ndlela, ukuvumelana kwe-angular kwama-LED abomvu, aluhlaza, naluhlaza kuzothinta kakhulu ukuvumelana kwebhalansi emhlophe kuma-engeli ahlukene, futhi kuthinte ngokuqondile ukuthembeka kombala wevidiyo esibonisini. Ukufeza ukuvumelana okuhambisanayo kwezinguquko zokukhanya kwama-LED abomvu, aluhlaza okwesibhakabhaka nama-engeli ahlukene, kuyadingeka ukwenza ngokuqinile ukwakheka kwesayensi ekwakhiweni kwelensi yokupakisha kanye nokukhethwa kwezinto ezingavuthiwe, okuncike ezingeni lobuchwepheshe umphakeli wokupakisha. Kungakhathaliseki ukuthi kuhle kangakanani ibhalansi emhlophe yokuqondisa okujwayelekile, uma ukuhambisana kwe-engeli ye-LED kungekuhle, umphumela webhalansi omhlophe wama-engeli ahlukene esikrini sonke uzoba mubi.
6. Izici zokunciphisa
Ngemuva kokuthi isibonisi se-LED sisebenza isikhathi eside, ukukhanya kuzokwehla futhi umbala wesibonisi uzobe ungahambisani, okubangelwa ngokuyinhloko ukuncishiswa kokukhanya kwedivayisi ye-LED. Ukuncishiswa kokukhanya kwe-LED kuzonciphisa ukukhanya kwaso sonke isikrini sesibonisi se-LED. Ukungahambisani kokuncishiswa kokukhanya kwama-LED abomvu, aluhlaza naluhlaza kuzodala ukungqubuzana kombala wesibonisi se-LED. Izibani ze-LED zekhwalithi ephezulu zingakwazi ukulawula kahle ubukhulu bokuncishiswa kokukhanya. Ngokwezinga lokukhanyisa okungu-20mA ekamelweni lokushisa amahora angu-1000, ukuncishiswa okubomvu kufanele kube ngaphansi kuka-2%, futhi ukuncishiswa okuluhlaza okwesibhakabhaka nokuluhlaza kufanele kube ngaphansi kuka-10%. Ngakho-ke, zama ukungasebenzisi i-20mA yamanje kuma-LED aluhlaza okwesibhakabhaka nokuluhlaza ekwakhiweni kwesibonisi, futhi kungcono kakhulu ukusebenzisa kuphela u-70% kuya ku-80% wamanje olinganiselwe.
Ngokungeziwe ezicini zokuthibaza ezihlobene nezici zama-LED abomvu, aluhlaza naluhlaza ngokwawo, amanje asetshenziswayo, idizayini yokukhipha ukushisa kwebhodi le-PCB, nezinga lokushisa elizungezile lesikrini sokubonisa konke kuthinta ukuncipha.
7. Usayizi
Usayizi wedivayisi ye-LED uthinta ibanga lephikseli lesibonisi se-LED, okungukuthi, ukulungiswa. Uhlobo lwe-SMD3535 LEDs lusetshenziswa kakhuluP6, P8, P10 isibonisi se-LED sangaphandle, I-SMD2121 LED isetshenziswa kakhuluP2.5,P2.6,P2.97,P3.91 isikrini sasendlini . Ngokwesisekelo sokuthi ukuphakama kwephikseli kuhlala kungashintshiwe, ubukhulu bezibani ze-LED buyanda, obungakhuphula indawo yokubonisa futhi bunciphise ubuhlalu. Kodwa-ke, ngenxa yokunciphisa indawo emnyama, umehluko uzoncishiswa. Ngokuphambene nalokho, ubukhulu be-LED buyancipha,okunciphisa indawo yokubonisa futhi kwandisa okusanhlamvu, indawo emnyama iyanda, ikhulisa izinga lokungafani.
8. Isikhathi sokuphila
Ukuphila okucatshangwayo kwesibani se-LED amahora angu-100,000, okuyinde kakhulu kunezinye izingxenye zesibonisi se-LED. Ngakho-ke, inqobo nje uma ikhwalithi yezibani ze-LED iqinisekisiwe, ukusebenza kwamanje kufanelekile, idizayini ye-PCB yokushisa ukushisa inengqondo, futhi inqubo yokukhiqiza isibonisi iqinile, izibani ze-LED zizoba izingxenye ezihlala isikhathi eside kakhulu zodonga lwevidiyo ye-LED.
Amamojula e-LED ahlanganisa u-70% yenani lezibonisi ze-LED, ngakho amamojula e-LED angakwazi ukunquma ikhwalithi yezibonisi ze-LED. Izimfuneko zobuchwepheshe obuphezulu zesikrini sokubonisa se-LED ziyithrendi yokuthuthukiswa kwesikhathi esizayo. Kusukela ekulawuleni amamojula e-LED, ukukhuthaza ukuguqulwa kweShayina ukusuka ezweni elikhulu lokukhiqiza isibonisi se-LED ukuya ezweni elinamandla lokukhiqiza isibonisi se-LED.
