Uhlalutyo lweTekhnoloji yokuBonisa i-COB ye-LED kunye neZibonelelo zeSicelo

I-COB (i-Chip kwiBhodi) Iziboniso ze-LED zibuchwephesha obuphezulu bokubonisa obufikelela ukuhlanganiswa okuphezulu kunye nokusebenza okuphezulu ngokupakisha ngokuthe ngqo ii-chips ze-LED kwiibhodi zeesekethe. Xa kuthelekiswa ne-SMD yendabuko (i-Surface Mount Device) iziboniso ze-LED, itekhnoloji ye-COB ibonelela ngeenzuzo ezibalulekileyo ekuthembekeni, ukufana okufanayo, kunye namava okubukela. Kwiminyaka yakutshanje, ibisetyenziswa kakhulu kwimiboniso yentengiso, kwimidlalo yeqonga, kunye -nokuhlolwa okuphezulu.

Ukusuka kumbono wobugcisa, eyona nto iphambili yeCOB LED iziboniso ilele kwipakethe yazo. I-chip igxininiswe ngokuthe ngqo kwi-substrate kwaye ikhuselwe nge-epoxy resin okanye i-silicone, inciphisa kakhulu inani lamalungu e-solder kwaye ngaloo ndlela izinga lokungaphumeleli. Olu luyilo aluphuculi kuphela ukungcangcazela kwemveliso kunye nokuchasana kwempembelelo kodwa kwakhona kusombulula ngempumelelo ingxaki "yokukhanya okufileyo" eqhelekileyo kwizikrini zemveli ze-LED. Ngaphaya koko, itekhnoloji ye-COB ibonelela ngombala omncinci we-pixel, ovumela ukusonjululwa okuphezulu kunye nemifanekiso eneenkcukacha ezininzi, ecacileyo, iyenze ilungele ukujongwa ngokusondeleyo{3}.

Ngokumalunga nomgangatho wokubonisa, iziboniso zeCOB ze-LED zinika umahluko obalaseleyo kunye nokuveliswa kombala. Ngenxa yokuba umaleko wokupakisha wenza okuchanekileyo ngakumbi ukusetyenzwa kwe-optical yesibini kumthombo wokukhanya, ukuhanjiswa kokukhanya kufana kakhulu, kuthintelwa isiphumo "sobunkonkoni" esiqhelekileyo kwizikrini zemveli. Ngaphaya koko, izinga eliphezulu lokuhlaziya kunye nokusetyenziswa kwamandla aphantsi kuyenza ibe lolona khetho lubalaseleyo lokubonisa umfanekiso oguqukayo kunye nokugcinwa kwamandla.

Okwangoku, iziboniso ze-COB ze-LED ziye zangena kancinci kancinci-kwiimarike zokugqibela ezifana namaziko omyalelo,{1}}ukuthengisa okuphakamileyo, kunye nenyani yokufota. Ngokudityaniswa kobuchwephesha obuncinci/buncinci be-LED, iziboniso zeCOB zilindeleke ukuba zinciphise ngakumbi ubungakanani, ziphucule ukuqaqamba, kwaye zandise ukusebenza kakuhle kwamandla, zibe lukhokelo lophuhliso oluphambili-kwimarike yokubonisa isikrini. Nangona iindleko zayo zokuvelisa zihlala ziphezulu kunezisombululo zemveli, ukukhuphisana kwe-COB LED kwimarike kuya kuqhubeka nokukhula njengoko iteknoloji ikhula kwaye ikhula.
