Ukuboniswa kwe-LEDUkuthuthukiswa Kwezimboni kuze kube manje, kufaka phakathi ukuboniswa kwe-cob, kuqhamuke ubuchwepheshe obuhlukahlukene bokupakisha ukukhiqiza. Kusuka kwinqubo yesibani esedlule, ukunamathisela kwe-Pay Astere (SMD), ekuvezeni ubuchwepheshe bokupakisha kwe-COB, bese ekugcineni ekuqubukeni kobuchwepheshe bokupakisha kwe-GOB.
I-SMD: Amadivayisi afakiwe angaphezulu komhlaba. Amadivayisi afakwe ebusweni. Imikhiqizo ye-LED ehlanganiswe nge-SMD (Technology Technology) yizimpawu zamaLamp, zisekela, amaseli we-crystal, ukuhola, ama-epoxy resins nezinye izinto ezifakwe ezinhlokweni ezihlukile zobuhlalu bezibani. Ubuhlalu beLamp bukadelwe ebhodini lokujikeleza ngokushisa okuphezulu bukhomba i-welding ngomshini we-smt wejubane eliphezulu, futhi iyunithi lokubonisa elinezikhala ezahlukahlukene lenziwe. Kodwa-ke, ngenxa yokuba khona kweziphambeko ezinkulu, ayikwazi ukufeza isidingo samakethe samanje. I-Cob Package, ebizwa nge-chips ebhodini, ubuchwepheshe bokuxazulula inkinga yokuhlanza ukushisa okuholwa. Uma kuqhathaniswa no-in-line ne-SMD, kubonakaliswa ukulondolozwa kwesikhala, ukufakwa okwenziwe lula kanye nokuphathwa okusebenzayo okushisayo. I-GOB, isifinyezo se-glue ebhodini, kuwubuchwepheshe be-encppApption eklanyelwe ukuxazulula inkinga yokuvikelwa kokukhanya kwe-LED. Ikwamukela impahla entsha evelayo ebonakalayo yokuvumelanisa i-substrate kanye neyunithi yayo yokufaka i-LED ukwakha ukuvikelwa okusebenzayo. Izinto ezibonakalayo akuyona nje into esobala kakhulu, kepha futhi zinokuphakelayo okushisayo. I-Gob Spacesing encane ingahle ivumelane nanoma iyiphi indawo enokhahlo, ukuze ifinyelele emgqeni weqiniso woMswakama-Ubufakazi, Ukungenzi manzi, ubufakazi bothuli, umthelela olwa nama-anti, anti-UV kanye nezinye izici; Imikhiqizo yokubonisa ye-GOB ngokuvamile idala amahora angama-72 ngemuva komhlangano naphambi kwe-gluing, futhi isibani siyahlolwa. Ngemuva kokugcwala, ukuguga kwamanye amahora angama-24 ukuqinisekisa ikhwalithi yomkhiqizo futhi.
Ngokuvamile, ukufakwa kwe-COB noma kwe-GOB ukuhlanganisa izinto ezibonakalayo ezibonakalayo kumamojula we-cob noma ama-gob ngendlela yokubumba noma ekuhlolweni, ukuqedela ukuvikelwa kwemodyuli yonke, futhi kwakha indlela esobala yokukhanya. Ingaphezulu lemodyuli yonke ingumzimba osobala, ngaphandle kokugxila noma ukwelashwa kwe-astigmatism ngaphezulu kwemodyuli. Umthombo wokukhanya kwephuzu ngaphakathi komzimba wephakheji usobala, ngakho-ke kuzoba nokukhanya kwe-crosstalk phakathi komthombo wokukhanya kwephuzu. Ngaleso sikhathi, ngoba okuphakathi kokubona phakathi komzimba wephakheji esobala kanye nomoya ongaphezulu kwehlukile, inkomba eyedlulayo yomzimba wephakheji esobala inkulu kunaleyo. Ngale ndlela, kuzoba nokubonakaliswa okuphelele kokukhanya esibonakalayo phakathi komzimba wephakheji nomoya, nokukhanya okuthile kuzobuyela ngaphakathi komzimba wephakheji futhi ulahlekelwe. Ngale ndlela, ukukhuluma inkulumo kususelwa kulokho okukhanyayo okungenhla kanye nezinkinga zokubona okubuyiselwe emuva kwiphakheji kuzodala ukungcola okukhulu, futhi kuholele ekunciphiseni okukhulu kwemodyuli ye-LED COB / GOB yokubonisa imodyuli yokuphikisana. Ngaphezu kwalokho, kuzoba nomehluko wendlela ye-optical phakathi kwamamojula ngenxa yamaphutha kwinqubo yokubumba phakathi kwamamojula ahlukene kwimodi yokupakisha yokubuyisa, okuzoholela umehluko wombala ohlukile phakathi kwamamojula we-COB / GOB ahlukahlukene. Ngenxa yalokhu, ukuboniswa kwe-LED okuhlanganiswe yi-COB / GOB kuzoba nomehluko omkhulu wombala wokubuka lapho isikrini simnyama futhi sintula umehluko lapho isikrini sikhonjiswa, okuzothinta umphumela wokubonisa wesikrini sonke isikrini. Ikakhulu kwisibonisi esincane se-HD ye-HD, lokhu kusebenza okungekuhle kokubuka kube kubi kakhulu.
