Niki COB LED Yerekana Mubyukuri?
Bitewe nuko abantu bakurikirana ultra-high ibisobanuro byerekanwe byerekanwe, pigiseli ya pigiseli ya LED yerekana ihora igabanuka.
Nkibisekuru byambere byerekana tekinoroji, gakondo ya SMD yerekanwe yarakuze cyanenyuma yimyaka irenga icumi yaiterambere.
None, niyihe nzira ya tekinike amaherezo izifuza mugihe cya micro iyobora?
Hamwe niterambere rya LED yerekana tekinoroji, inzira tekinike nka COB （Nibihe bigufi kuri Chip On Board） isohoka.
Nanone, inzira zitandukanye zo gupakira zirashobora guhuzwa nuburyo butandukanye bwa chip.
SMD, izwi nkibikoresho byashizwe hejuru, bivuga gukoresha tekinoroji yububiko bwo gupakira ibicuruzwa LED.
Irashobora gushiramo igikombe cyamatara, bracket, element ya kristu, nibindi bikoresho muburyo butandukanye bwamasaro.
Mugihe utanga icyerekezo cyerekana umwanya utandukanye wa mini LED yerekana, isaro ryamatara risudira kumuzunguruko ukoresheje imashini yihuta ya SMT hamwe nubushyuhe bwo hejuru bwo gusudira.
Urebye ingorane za tekiniki mugihe cyo gufunga, abayikora bahitamo SMD kugirango itange umwanya muto muto wa LED yerekana ecran.
SMD nubuhanga bwibanze kuri micro LED yerekana ecran ifite pigiseli iri munsi ya 10mm kumasoko.
Ku rundi ruhande, COB, ngufi kuri Chip On Board, ni tekinoroji nshya yo gupakira ikubiyemo ibyuma bya LED, aho kuba amatara ya LED, kuri PCB.
Kubwibyo, COB-LED izabohorwa mubunini bwumubiri wa SMD kugirango ikemurwe neza nka P0.9375.
Imibaremicro yerekanwe kwerekana muri P0.9375mm, P1.25mm, P1.5625 mm na P1.875 irahari hamwe na COB.
Byongeye kandi, ntawahakana ko COB ifite imiterere myiza yumubiri.
Module igizwe na COB ntabwo yoroshye gusa kurenza SMD ariko ifite nuburyo bunini bwo kureba.
Ugereranije na SMD, ibyo COB yayoboye kwerekana bishobora kukuzanira inyungu nkuko bikurikira:
1; Gukwirakwiza ubushyuhe buhebuje
Imwe mu ntego z'ikoranabuhanga ni ugukemura ikibazo cyo gukwirakwiza ubushyuhe bwa SMD na DIP.
Imiterere yoroshye itanga inyungu kurenza ubundi bwoko bubiri bwimirasire.
2; Bikwiranye na pigiseli ntoya ya LED Yerekana
Nkuko chip ihujwe neza nubuyobozi bwa PCB, intera iri hagati ya buri gice iragufi kugirango igabanye pigiseli kugirango itange abakiriya amashusho asobanutse.
3; Koroshya ibyo gupakira
Nkuko twabivuze haruguru, imiterere ya COB LED iroroshye kuruta SMD na GOB, kuburyo gupakira biroroshye, kandi.
4; Urwego rwo hejuru rutagira amazi
Hamwe na chip idasanzwe ku kibaho cya module yometse, irashobora kurinda neza LED kuri module ya LED amazi cyangwa ubuhehere.
5; Kurwanya Kurwanya
Igishushanyo cyihariye cyo gushushanya hamwe no kurwanya kugongana gushobora kugira imikorere yibikorwa, bitanga uburinzi bukabije kuri LED mu ngaruka zitandukanye.
6; Kurenga umukungugu.
Hamwe nimikorere yikimenyetso kinini cyibikoresho bishya, ecran ya COB LED ya ecran ya YONWAYTECH LED nta mukungugu urimo rwose kandi usobanutse neza kandi itanga imikorere myiza igaragara hamwe nigipimo cyinshi cyo kugarura ubuyanja.
Impamvu yo kwizerwa kwinshi nuko tekinoroji ya COB ishobora gukuraho ihuriro ryo kugenzura mugikorwa kimwe cyo gukora itara.
Byongeye kandi, ikuraho kandi itara ryamatara hejuru yuburyo bwo gusudira, kugirango ubushyuhe bwo hejuru muburyo gakondo butazagira ingaruka kuri chip ya LED n'umurongo wo gusudira.
Gukwirakwiza ubushyuhe buhebuje no kurwanya okiside nabyo bigira uruhare mu kwizerwa cyane.
Ikirenzeho, COB ikoresha tekinoroji yo hejuru yo gutwikira kugirango ikumire LED yerekanwe biterwa n'amazi, ubushuhe, UV, nibindi byangiritse.
Ifasha ibihe byose-ikirere kandi irashobora gukora mubushyuhe bukabije muri dogere -30 kugeza kuri 80.
Inzira yuzuye yo kurinda irinda kugongana cyangwa gushushanya.
Mini LED yerekana ecran irashobora no guhanagurwa nigitambaro gitose iyo cyanduye.
Hamwe namakuru yavuzwe haruguru, urashobora kubona ko tekinoroji ya COB iruta tekinoroji ya SMD muri ecran ya LED.
Niba kandi ushakaMicro LED yerekana, urashobora kwerekeza kubicuruzwa bimwe bya YONWAYTECH LED YEREKANA.
Menyesha na YONWAYTECH LED DISPLAY itsinda kugirango ubone ibisobanuro birambuye nyamuneka.
