Njengobuchwepheshe bokubonisa obulandelayo-, izibonisi ze-COB (Chip on Board) ze-LED ziklanyelwe ukunqoba imikhawulo yobuchwepheshe be-SMD (i-surface mount) evamile ngamaphakheji ahlanganiswe kakhulu, afinyelela{1}}ukuminyana okuphezulu, okuthembeke kakhulu, nezibonisi ezigxilisa kakhulu. Le ndlela yokuklama ayigcini ngokuchaza kabusha imingcele yokusebenza kwezibonisi ze-LED kodwa futhi inikeza isisombululo esisha-sezimo zokubonisa eziphezulu.
Ngokombono wezobuchwepheshe, idizayini ye-COB iphasela ngokuqondile i-chip ye-LED ku-substrate ye-PCB, isusa ubakaki ovamile kanye nesakhiwo sephedi, yehlisa ngokuphawulekayo ukuphakama kwephikseli futhi ivumele{0}}ukusetshenziswa okuhle kwe-pitch kwama-Mini/Micro LEDs. Le ndlela ehlanganisiwe inyusa kakhulu ukuminyana kwamaphikseli endaweni yeyunithi ngayinye, ivumela, isibonelo, -okuphezulu{3}}okuboniswa kwencazelo okungaphansi kwamaphikseli angu-1.0. Ubuchwepheshe bokupakisha be-Coplanar buphinde bunciphise ubulukhuni besikrini, bunciphise i-moiré nokucwebezela, bunikeze okuhlangenwe nakho okubushelelezi ukuze kubukwe eduze{6}}.
Ukuthembeka kuwukucatshangelwa okuyisisekelo ekwakhiweni kwe-COB. I-Chip-Ukupakishwa kwesikali kunikeza umgoqo ophathekayo weyunithi{2}}ekhiphayo ukukhanya, iyivikele ngempumelelo emswakameni, othulini, nasekudlidlizeni, kanye nokunciphisa amazinga okuhluleka ngohlelo lobukhulu uma kuqhathaniswa ne-SMD. Ngaphezu kwalokho, i-COB isebenzisa inqubo yokwemboza emnyama ngokuphelele ukuze ithuthukise ukugqama, kuyilapho indawo yayo{4}}yomthombo wokukhanya womthombo isusa ubuhlalu. Ihlanganiswe nobuchwepheshe be-High Dynamic Range (HDR), i-COB iletha ukuhlukaniswa kombala okungokoqobo kanye nemininingwane yesigcawu esimnyama.
Ezingeni lesicelo, idizayini ye-COB igxile ekuzivumelaniseni nezimo kunoma yisiphi isimo. Kungakhathaliseki ukuthi ukuboniswa kwedatha okunembile egumbini lokulawula noma ukukhanya okugxilile nesithunzi okunikezwayo esiteji setiyetha, ukungaguquguquki kwayo okuphezulu, ukusetshenziswa kwamandla okuphansi, nokuphila isikhathi eside kuhlangabezana nezimfuneko ezidingekayo. Ngokuzayo, ngokuhlangana kwe-flip-chip kanye nobuchwepheshe bokudlulisa ngobuningi, i-COB izoqhubekisela phambili ukuvela kwezibonisi ze-LED ekuhlanganiseni okungenamthungo kanye nezibonisi ezivumelana nezimo, iqhubeke nokuhola emisha embonini yokubonisa.
