1. Intshayelelo
Njengoko izicelo zesikrini sokubonisa i-LED zisasazeka ngakumbi, iimfuno zomgangatho wemveliso kunye nokusebenza kokubonisa ziye zanda. Itekhnoloji ye-SMD yesiNtu ayisakwazi ukuhlangabezana neemfuno zezinye izicelo. Ke ngoko, abanye abavelisi batshintshela kwiindlela ezintsha zokugquma njengetekhnoloji yeCOB, ngelixa abanye bephucula itekhnoloji ye-SMD. Itekhnoloji ye-GOB kukuphindwa kwenkqubo ephuculweyo ye-SMD encapsulation.
Imboni yokubonisa i-LED iphuhlise iindlela ezahlukeneyo zokufaka i-encapsulation, kuquka iziboniso ze-COB ze-LED. Ukususela kwi-DIP yangaphambili (i-Direct Insertion Package) iteknoloji kwi-SMD (i-Surface-Mount Device) iteknoloji, emva koko ekuveleni kwe-COB (Chip kwiBhodi) i-encapsulation, kwaye ekugqibeleni ukufika kwe-GOB (iGlue kwiBhodi) i-encapsulation.
Ngaba itekhnoloji yeGOB inokwenza usetyenziso olubanzi lwezikrini zokubonisa i-LED? Zeziphi iindlela esinokuzilindela kuphuhliso lweemarike zexesha elizayo zeGOB? Masiqhubele phambili.
2. Yintoni i-GOB Encapsulation Technology?
2.1Umboniso we-GOB we-LEDsisibonisi sesikrini se-LED esikhusela kakhulu, esibonelela ngamanzi, ubungqina bokufuma, ukunganyangeki, uthuli, ukunqanda ukubola, ukunyathela ukukhanya okuluhlaza okwesibhakabhaka, ukunyathela ityuwa, kunye ne-anti-static. Ayichaphazeli kakubi ukutshatyalaliswa kobushushu okanye ukulahleka kokukhanya. Uvavanyo olubanzi lubonisa ukuba iglue esetyenziswe kwi-GOB inceda nasekulahlekeni kobushushu, ukunciphisa izinga lokungaphumeleli kwee-LED, ukuphucula ukuzinza kwesiboniso, kwaye ngaloo ndlela yandisa ubomi bayo.
2.2 Ngokusetyenzwa kwe-GOB, iindawo zephikseli zegranular zangaphambili kumphezulu wesikrini se-GOB LED ziguqulwa zibe ngumphezulu ogudileyo, osicaba, ophumeza inguqu ukusuka kwindawo yokukhanya ukuya kwindawo yokukhanya komphandle. Oku kwenza ukukhanya kwepaneli yesikrini se-LED kufane ngakumbi kwaye isiphumo somboniso sicace kwaye sicace ngakumbi. Iphucula kakhulu i-angle yokujonga (phantse i-180 ° ngokuthe tye kwaye ngokuthe nkqo), iphelisa ngokufanelekileyo iipateni ze-moiré, iphucula kakhulu ukuchasana kwemveliso, inciphisa i-glare kunye nemiphumo emihle, kwaye inciphisa ukukhathala okubonakalayo.
3. Yintoni i-COB Encapsulation Technology?
I-COB encapsulation ithetha ngokuthe ngqo ukubamba itshiphu kwi-PCB substrate yoqhagamshelo lombane. Yaziswa ngokuyinhloko ukusombulula ingxaki yokutshatyalaliswa kobushushu kwiindonga zevidiyo ze-LED. Xa kuthelekiswa ne-DIP kunye ne-SMD, i-COB i-encapsulation ibonakaliswe ngokugcina indawo, imisebenzi ye-encapsulation elula, kunye nolawulo olusebenzayo lwe-thermal. Okwangoku, i-COB encapsulation isetyenziswa kakhuluumboniso oqaqambileyo we-LED.
4. Ziziphi izinto eziluncedo kwi-COB LED Display?
Incinci kakhulu kwaye iKhanya:Ngokweemfuno zabathengi, iibhodi zePCB ezinobunzima obusuka kwi-0.4 ukuya kwi-1.2mm zingasetyenziswa, ukunciphisa ubunzima ukuya kuthi ga kwisinye kwisithathu seemveliso zemveli, zithobe kakhulu iindleko zezakhiwo, ezothutho kunye nezobunjineli kubathengi.
Impembelelo kunye noNyango loxinzelelo:Umboniso we-COB we-LED ufaka i-chip ye-LED ngokuthe ngqo kwindawo ye-concave yebhodi ye-PCB, emva koko uyifake kwaye uyinyange ngeglue epoxy resin. Umphezulu wendawo yokukhanya uyaphuma, uwenza ube mpuluswa kwaye unzima, awunyangeki, kwaye unganxibi.
Iengile yokuJonga eBanzi:I-COB encapsulation isebenzisa ukukhanya okungekho nzulu kokukhanya okungqukuva, kunye ne-engile yokujonga enkulu kune-175 degrees, kufutshane ne-180 degrees, kwaye ineziphumo ezibalaseleyo zokukhanya okukhanyayo.
Ukutshatyalaliswa koBubushushu obunamandla:Isikrini se-COB se-LED sifaka ukukhanya kwibhodi ye-PCB, kunye ne-foil yobhedu kwibhodi ye-PCB ngokukhawuleza iqhuba ubushushu be-core light. Ubukhulu befoyile yobhedu yebhodi yePCB ineemfuno zenkqubo engqongqo, edityaniswa neenkqubo zokubekwa kwegolide, phantse ukuphelisa ukuthomalalisa ukukhanya. Ke, zimbalwa izibane ezifileyo, ezandisa kakhulu ixesha lokuphila.
Ukunganxibi kwaye kulula ukuCoca:Izikrini ze-COB ze-LED zomgangatho wokukhanya ziphumela kwimilo engqukuva, iyenza igudileyo kwaye ilukhuni, ixhathise impembelelo kwaye inganxibi. Ukuba inqaku elibi livela, linokulungiswa kwinqanaba ngenqaku. Akukho maski, kwaye uthuli lunokucocwa ngamanzi okanye ngelaphu.
UkuGqwesa kweMozulu Yonke:Unyango lokukhuselwa kathathu lubonelela ngokugqwesileyo kokungangeni manzi, ukufuma-ubungqina, ubungqina bokuhlwa, uthuli, i-anti-static, i-oxidation, kunye nokuxhathisa kwe-UV. Iyakwazi ukusebenza ngokuqhelekileyo kwiindawo zobushushu ukusuka ku -30°C ukuya kuma-80°C.
