Yintoni ngokwenene i-COB yokubonisa i-LED?

Ngenxa yokusukelana nomntu kwinkcazo ephezulu-phezulu ye-LED, i-pixel pitch yeziboniso ze-LED zihlala zincipha.

Njengesizukulwana sokuqala setekhnoloji yokubonisa, umboniso we-SMD wendabuko ukhule kakhuluemva kweminyaka engaphezu kweshumiuphuhliso.

Ke, yeyiphi indlela yobuchwephesha eya kuthi ekugqibeleni inqwenele ukuya kwixesha le-micro led display?

Ngophuhliso lwethekhnoloji yokubonisa i-LED, iindlela zobugcisa ezifana ne-COB (Eyifutshane kwi-Chip On Board) iphuma.

Kwakhona, iindlela ezahlukeneyo zokupakisha zinokudityaniswa nezakhiwo ze-chip ezahlukeneyo.

I-SMD, eyaziwa ngokuba zizixhobo ezixhonywe phezulu, ibhekisa ekusebenziseni itekhnoloji yokubeka umphezulu ukupakisha iimveliso ze-LED.

Iyakwazi ukugquma ikomityi yesibane, isibiyeli, ikristale element, kunye nezinye izinto kwiinkcukacha ezahlukeneyo zamaso esibane.

Xa uvelisa iyunithi yokubonisa kunye nesithuba esahlukileyo kwizikrini zokubonisa i-LED encinci, i-bead yesibane idityaniswe kwibhodi yesekethe ngomatshini we-SMT okhawulezayo kunye ne-high-temperature reflow welding. 

Ukuqwalasela ubunzima bobugcisa ngexesha lokufakwa kwe-encapsulation, abavelisi bakhetha i-SMD ukuvelisa isikrini esincinci sedijithali se-LED.

I-SMD yitekhnoloji ephambili yezikrini zokubonisa ze-LED ezincinci ezinesithuba sepixel esingaphantsi kwe-10mm kwimarike.

Kwelinye icala, i-COB, imfutshane kwiChip On Board, yitekhnoloji entsha yokupakisha efaka iitshiphusi ze-LED, endaweni yezibane ze-LED, ngqo kwi-PCB.

Ngoko ke, i-COB-LED iya kukhululwa kubukhulu bomzimba we-SMD kwisisombululo esiphezulu njenge-P0.9375.

IdijithaliIzikrini ze-micro led display display in P0.9375mm, P1.25mm, P1.5625 mm kunye ne-P1.875 ziyafumaneka nge-COB.

Ngaphaya koko, alinakuphikiswa ukuba i-COB ineempawu zomzimba ezingcono.

Iimodyuli ezifakwe kwi-COB azikhaphuki nje kuphela kune-SMD kodwa zinombono omkhulu.

Xa kuthelekiswa ne-SMD, yeyiphi i-COB ekhokelela kumboniso enokuzisa inzuzo kuwe njengalapha ngezantsi:

1;Ukutshatyalaliswa kobushushu obugqwesileyo

Enye yeenjongo zale teknoloji kukujongana nengxaki yokutshatyalaliswa kobushushu be-SMD kunye ne-DIP.

Ulwakhiwo olulula lunika inzuzo ngaphezu kwezinye iindidi ezimbini zemitha yobushushu.

2;Ifanelekile kumboniso we-pixel omxinwa we-LED

Njengoko iitshiphusi ziqhagamshelwe ngokuthe ngqo kwibhodi yePCB, imigama phakathi kweyunithi nganye imxinwa ukuze kuncitshiswe iphikseli yepitch ukubonelela abathengi ngemifanekiso ecacileyo.

3;Yenza lula ukupakishwa

Njengoko sichazile ngasentla, isakhiwo se-COB LED silula kune-SMD kunye ne-GOB, ngoko ke inkqubo yokupakisha ilula, nayo.

4;Inqanaba eliphakamileyo lokungangeni manzi

Nge-chip ye-innovative ebhodini yemodyuli edibeneyo, inokukhusela kakuhle i-LED kwimodyuli ye-LED emanzini okanye kumswakama.

5;Ngcono Anti-ukungqubana

Uyilo olukhethekileyo lwemodyuli kunye negluing yokuchasana ne-anti-collision ekwaziyo ukuba nomsebenzi wobungqina bomothuko, inika ukhuseleko oluphezulu lwe-LED kwiimpembelelo ezahlukeneyo.

6;Ukugqithisa uthuli.

Ngokutywinwa okuphezulu kokusebenza kwezinto ezintsha, iphaneli yesikrini ye-COB ye-LED evela kwi-YONWAYTECH LED ayinalo uthuli ngokupheleleyo ngokucaca okugqwesileyo kwaye ibonelela ngokusebenza okubonakalayo okugqwesileyo okunezinga eliphezulu lokuhlaziya kunye nombala ofanayo.

Isizathu sokuthembeka okuphezulu kukuba iteknoloji yeCOB inokuphelisa ikhonkco lokulawula kwinkqubo yokuvelisa isibane esisodwa.

Ukongeza, iphinda isuse i-bead yesibane phezu kwenkqubo ye-welding ye-reflow, ukwenzela ukuba ukushisa okuphezulu kwindlela yendabuko akuyi kuchaphazela i-chip ye-LED kunye ne-welding line.

Ukutshatyalaliswa kobushushu obugqwesileyo kunye nokumelana ne-oxidation nako kunegalelo ekuthembekeni okuphezulu.

Ngaphezu koko, i-COB yamkela itekhnoloji yokwambathisa ekumgangatho ophezulu ukunqanda ukusilela ekuboniseni i-LED okubangelwa ngamanzi, ukufuma, i-UV, kunye nolunye umonakalo.

Ixhasa ukusebenza kwemozulu yonke kwaye isengasebenza kumaqondo obushushu agqithisileyo kwi--30 ukuya +80 degrees.

Inkqubo ebanzi yokukhusela ikhusela ukungqubana okanye imikrwelo.

Izikrini ezincinci zokubonisa i-LED zinokucocwa ngelaphu elimanzi ukuba zimdaka.

Ngolwazi olungasentla, unokuqaphela ukuba itekhnoloji ye-COB iphezulu kunetekhnoloji ye-SMD kwiscreen sokubonisa se-LED. 

Kwaye ukuba ufunaIziboniso ze-Micro LED, ungabhekisa kwezinye iimveliso ze YONWAYTECH LED DISPLAY.

Qhagamshelana neqela le-YONWAYTECH LED DISPLAY ukuze ufumane iinkcukacha ezingaphezulu nceda.
