I-GOB vs. COB 3 Mins Quick Guide 2024

1. Isingeniso

Njengoba izinhlelo zokusebenza zesikrini sokubonisa i-LED zisakazeka kakhulu, izimfuno zekhwalithi yomkhiqizo nokusebenza kwesibonisi ziye zanda. Ubuchwepheshe bendabuko be-SMD abusakwazi ukuhlangabezana nezidingo zezinye izinhlelo zokusebenza. Ngakho-ke, abanye abakhiqizi bashintshela ezindleleni ezintsha zokuhlanganisa njengobuchwepheshe be-COB, kuyilapho abanye bethuthuka kubuchwepheshe be-SMD. Ubuchwepheshe be-GOB buyimpinda yenqubo ye-encapsulation ye-SMD ethuthukisiwe.

Imboni yokubonisa i-LED ithuthukise izindlela ezihlukahlukene zokuhlanganisa, kuhlanganise nezibonisi ze-COB LED. Kusukela kubuchwepheshe bangaphambili be-DIP (Direct Insertion Package) kuya kubuchwepheshe be-SMD (Surface-Mount Device), bese kuya ekuveleni kwe-COB (Chip on Board) encapsulation, futhi ekugcineni ukuvela kwe-GOB (Glue on Board) encapsulation.

Ingabe ubuchwepheshe be-GOB bungakwazi ukunika amandla izinhlelo zokusebenza ezibanzi zezikrini zokubonisa ze-LED? Yimaphi amathrendi esingawalindela ekuthuthukisweni kwemakethe ye-GOB yesikhathi esizayo? Asiqhubeke.

2. Iyini i-GOB Encapsulation Technology?

2.1Isibonisi se-GOB LEDiyisikrini sokubonisa se-LED esivikela kakhulu, esinikeza amandla angangeni manzi, angenwa umswakama, amelana nokushayisana, angangenwa uthuli, ukumelana nokugqwala, ukumelana nokukhanya okuluhlaza okwesibhakabhaka, ukumelana nosawoti, namandla e-anti-static. Akuthinti kabi ukukhishwa kokushisa noma ukulahlekelwa ukukhanya. Ukuhlola okubanzi kubonisa ukuthi ingcina esetshenziswa ku-GOB isiza ngisho nasekulahlekeni kokushisa, yehlise izinga lokuhluleka kwama-LED, ithuthukise ukuqina kwesibonisi, kanjalo nokwelula ubude baso bempilo.

2.2 Ngokucutshungulwa kwe-GOB, amaphoyinti ephikseli angaphambili ayimbudumbudu endaweni yesikrini se-GOB LED aguqulwa abe indawo ebushelelezi, eyisicaba, afinyelele uguquko ukusuka emthonjeni wokukhanya wephoyinti ukuya emthonjeni wokukhanya ongaphezulu. Lokhu kwenza ukukhanya kwephaneli yesikrini se-LED kufane kakhudlwana futhi umphumela wokubonisa ucace futhi ubonakale kakhudlwana. Ithuthukisa kakhulu i-engeli yokubuka (cishe ngo-180° ngokuvundlile futhi mpo), iqeda ngempumelelo amaphethini e-moiré, ithuthukisa kakhulu ukugqama komkhiqizo, inciphisa ukuxhopha nemiphumela ekhazimulayo, futhi idambise ukukhathala okubukwayo.

3. Iyini i-COB Encapsulation Technology?

I-COB encapsulation isho ukunamathisela ngokuqondile i-chip ku-substrate ye-PCB ukuze ixhunywe ugesi. Yethulwe ngokuyinhloko ukuxazulula inkinga yokukhishwa kokushisa kwezindonga zevidiyo ye-LED. Uma kuqhathaniswa ne-DIP ne-SMD, i-COB encapsulation ibonakala ngokulondoloza isikhala, imisebenzi ye-encapsulation eyenziwe lula, nokuphatha okushisayo okusebenzayo. Njengamanje, i-COB encapsulation isetshenziswa kakhulu kuisibonisi esihle se-LED.

4. Yiziphi Izinzuzo Zokuboniswa kwe-COB LED?

Izacile kakhulu futhi ilula:Ngokwezidingo zamakhasimende, amabhodi e-PCB anogqinsi olusukela ku-0.4 kuya ku-1.2mm angasetshenziswa, ehlise isisindo sibe kancane njengengxenye eyodwa kwezintathu yemikhiqizo yendabuko, ehlisa kakhulu izindleko zesakhiwo, ezokuthutha, nezobunjiniyela kumakhasimende.

Umthelela Nokumelana Nokucindezela:Isibonisi se-COB se-LED simboza i-chip ye-LED ngokuqondile endaweni eyi-concave yebhodi le-PCB, bese ihlanganisa futhi ikwelapha nge-epoxy resin glue. Ingaphezulu lephoyinti lokukhanya liyaphumela, lilenze libe bushelelezi futhi libe lukhuni, limelane nomthelela, futhi likwazi ukuguga.

I-engeli yokubuka ebanzi:I-COB encapsulation isebenzisa ukukhanya okungashoni kahle okuyisiyingi, okune-engeli yokubuka enkulu kuno-175 degrees, eduze nama-degree angu-180, futhi kunemiphumela emihle kakhulu yokukhanya okuhlukanisiwe.

Ukukhipha Ukushisa Okunamandla:Isikrini se-COB LED sihlanganisa ukukhanya ebhodini le-PCB, futhi i-foil yethusi ebhodini le-PCB iqhuba ngokushesha ukushisa kwenkambo yokukhanya. Ugqinsi lwe-foil yethusi lwebhodi le-PCB lunezidingo eziqinile zenqubo, ezihambisana nezinqubo zokucwenga igolide, ezicishe ziqede ukuncisha ukukhanya okukhulu. Ngakho-ke, zimbalwa izibani ezifile, ezinweba kakhulu isikhathi sokuphila.

Ingagugi futhi Kulula ukuyihlanza:Izikrini ze-COB ze-LED zephoyinti lokukhanya ziphuma zibe yindilinga, ziyenze ibe bushelelezi futhi ibe lukhuni, imelane nomthelela futhi imelane nokugqokwa. Uma iphuzu elibi livela, lingalungiswa iphuzu ngephuzu. Ayikho imaski, futhi uthuli lungahlanzwa ngamanzi noma ngendwangu.

Ubuhle Besimo Sezulu Sonke:Ukwelashwa kokuvikela kathathu kunikeza okungangeni manzi okuvelele, umswakama-umswakama, ukuvikela ukugqwala, ukuvikela uthuli, i-anti-static, i-oxidation, nokumelana ne-UV. Ingasebenza ngokujwayelekile ezindaweni zokushisa ezisukela ku -30°C kuya ku-80°C.

5. Uyini Umehluko Phakathi Kwe-COB ne-GOB?

Umehluko omkhulu phakathi kwe-COB ne-GOB ukule nqubo. Nakuba i-COB encapsulation inendawo ebushelelezi futhi ivikeleke kangcono kunokwejwayelekile kwe-SMD encapsulation, i-GOB encapsulation yengeza inqubo yokufaka iglue endaweni yesikrini, ithuthukisa ukuqina kwezibani ze-LED futhi kunciphisa kakhulu amathuba okuwa kokukhanya, okuyenza izinze kakhudlwana.

6. Yikuphi Okunenzuzo Kakhulu, i-COB noma i-GOB?

Ayikho impendulo eqondile yokuthi iyiphi engcono, i-COB LED display noma i-GOB LED display, njengoba ikhwalithi yobuchwepheshe be-encapsulation incike ezintweni ezihlukahlukene. Ukucatshangelwa okubalulekile ukuthi ingabe ukubeka phambili ukusebenza kahle kwezibani ze-LED noma ukuvikelwa okunikezwayo. Ubuchwepheshe be-encapsulation ngamunye bunezinzuzo zabo futhi abukwazi ukwahlulelwa emhlabeni wonke.

Uma ukhetha phakathi kwe-COB ne-GOB encapsulation, kubalulekile ukucabangela indawo yokufaka nesikhathi sokusebenza. Lezi zici zithinta ukulawulwa kwezindleko kanye nomehluko ekusebenzeni kwesibonisi.

7. isiphetho

Kokubili ubuchwepheshe be-GOB ne-COB encapsulation bunikeza izinzuzo ezihlukile zokuboniswa kwe-LED. I-GOB encapsulation ithuthukisa ukuvikeleka nokuzinza kwamalambu e-LED, ihlinzeka ngezakhiwo ezinhle kakhulu zokungangeni kwamanzi, ezingangenwa uthuli, nezingashayisani, kuyilapho ithuthukisa ukunqanyulwa kokushisa nokusebenza okubonakalayo. Ngakolunye uhlangothi, i-COB encapsulation ihamba phambili ekongeni isikhala, ukuphatha ukushisa okusebenzayo, kanye nokuhlinzeka ngesisombululo esingasindi, esimelana nomthelela. Ukukhetha phakathi kwe-COB ne-GOB encapsulation kuncike ezidingweni ezithile nezinto ezibalulekile endaweni yokufaka, njengokuqina, ukulawulwa kwezindleko, nekhwalithi yokubonisa. Ubuchwepheshe ngabunye bunamandla abo, futhi isinqumo kufanele senziwe ngokusekelwe ekuhlolweni okuphelele kwalezi zici.

Uma usadidekile nganoma yisiphi isici,xhumana nathi namuhla.I-RTLEDuzibophezele ekunikezeni izixazululo ezinhle kakhulu zokubonisa i-LED.
