N'ezie, usoro COB nwekwara "adịghị ike" ya.Nke mbụ bụ okwu ọnụ ahịa.Usoro COB na-akwụ ụgwọ karịa usoro mgbago elu.Nke a bụ n'ihi na usoro COB bụ n'ezie ọkwa mkpuchi, na elu elu bụ njikọ ọnụ.Tupu emejuputa usoro nrịgo elu, ihe irighiri kristal LED abanyelarị usoro encapsulation.Ọdịiche a emeela ka COB nwee ọnụ ụzọ itinye ego dị elu, ọnụ ahịa ọnụ ahịa, yana ọnụ ụzọ teknụzụ sitere na ihu azụmaahịa LED ihuenyo.Otú ọ dị, ọ bụrụ na "ngwugwu oriọna na ntinye ọnụ" nke usoro ntinye elu na-atụnyere usoro COB, a na-anabata mgbanwe ọnụ ahịa nke ọma, ọ na-enwekwa ọchịchọ maka ọnụ ahịa iji belata na nkwụsi ike usoro na mmepe ngwa ngwa.
Nke abụọ, nhụta anya nke ngwaahịa mkpuchi COB chọrọ mgbanwe teknụzụ n'oge.Gụnyere nkwekọ isi awọ nke gluu na-ekpuchi onwe ya na nkwụsi ike nke ọkwa nchapụta nke kristal na-egbuke egbuke, ọ na-anwale njikwa mma nke agbụ ụlọ ọrụ dum na ọkwa nke mgbanwe na-esote.Agbanyeghị, ọghọm a bụ ihe gbasara “ahụmahụ dị nro”.Site na usoro ọganihu nke nkà na ụzụ, ọtụtụ ụlọ ọrụ na ụlọ ọrụ ahụ ejirila nkà na ụzụ ndị dị mkpa maka ịnọgide na-ahụ anya nke mmepụta ihe dị ukwuu.
Nke atọ, mkpuchi COB na ngwaahịa nwere oghere pixel buru ibu na-abawanye "mgbagwoju anya mmepụta" nke ngwaahịa ahụ.N'ikwu ya n'ụzọ ọzọ, teknụzụ COB adịghị mma, ọ naghị emetụta ngwaahịa ndị nwere oghere P1.8.N'ihi na n'ebe dị anya karị, COB ga-eweta mmụba dị ịrịba ama karịa.- Nke a dị ka usoro ntinye elu enweghị ike dochie anya ngosi LED kpamkpam, n'ihi na na p5 ma ọ bụ karịa ngwaahịa, mgbagwoju anya nke usoro elu-elu na-eduga n'ịba ụba.A ga-ejikwa usoro COB n'ọdịnihu mee ihe na P1.2 na ngwaahịa dị n'okpuru.
Ọ bụ kpọmkwem n'ihi uru na ọghọm dị n'elu nke COB encapsulation obere pixel pitch LED ngosi na: 1.COB abụghị ụzọ mbụ nhọrọ maka obere pixel pitch LED ngosi.N'ihi na obere pixel pitch LED na-eji nwayọọ nwayọọ na-aga n'ihu site na ngwaahịa buru ibu, ọ ga-abụrịrị na ọ ga-eketa nkà na ụzụ tozuru okè na ikike mmepụta nke usoro elu-elu.Nke a mekwara ụkpụrụ nke taa n'elu-ndokwasa obere pixel pitch LEDs ogide ọtụtụ n'ime ahịa maka obere pixel pitch LED meziri.
2. COB bụ "omume a na-apụghị izere ezere" maka obere ihe ngosi pikselụ pikselụ LED ka ọ gaa n'ihu n'ịgbanwe na obere oghere na ngwa ime ụlọ dị elu.N'ihi na, na njupụta pikselụ dị elu, ọnụ ọgụgụ anwụ anwụ nke usoro elu-elu na-aghọ "nsogbu ntụpọ ngwaahịa agwụla."Teknụzụ COB nwere ike imeziwanye ihe ngosi oriọna nwụrụ anwụ nke obere ihe ngosi pixel pitch LED.N'otu oge ahụ, na iwu njedebe dị elu na ahịa ụlọ ọrụ nzipu ozi, isi ihe ngosi ngosi abụghị "ìhè" kama "nkasi obi na ntụkwasị obi" na-achịkwa.Nke a bụ kpọmkwem uru teknụzụ COB.
Ya mere, ebe ọ bụ na 2016, accelerated mmepe nke COB encapsulation obere pixel pitch LED ngosi nwere ike weere dị ka a Nchikota nke "obere pitch" na "elu-ọgwụgwụ ahịa".Ọrụ ahịa nke iwu a bụ na ụlọ ọrụ ihuenyo LED ndị na-adịghị etinye aka na ahịa nke iwu na ebe a na-ezigara enweghị mmasị na nkà na ụzụ COB;Companieslọ ọrụ ihuenyo LED na-elekwasị anya na ahịa nke iwu na ebe izipu nwere mmasị na mmepe nke teknụzụ COB.

Mgbanwe teknụzụ nke ngwaahịa ngosi LED enwetala usoro atọ: in-line, elu-mount, COB, na mgbanwe abụọ.Site na in-line, elu-mount, na COB pụtara ntakiri pitch na elu mkpebi.Usoro evolushọn a bụ ọganihu nke ngosi LED, ma ọ zụlitekwara ahịa ngwa ngwa dị elu karịa.Ya mere, ụdị mgbanwe teknụzụ a ga-aga n'ihu n'ọdịnihu?Azịza ya bụ ee.
Ikanam ihuenyo si inline ka elu nke mgbanwe, tumadi integrated usoro na oriọna beads ngwugwu nkọwa mgbanwe.Uru nke mgbanwe a bụ nke kachasị elu ike njikọta elu.Ihuenyo LED na obere pikselụ pipụ pikselụ, site na usoro elu-n’elu ruo na mgbanwe usoro COB, na mgbakwunye na usoro ntinye na mgbanwe ngwugwu, njikọta COB na ntinye ntinye nke encapsulation bụ usoro nke agbụ ụlọ ọrụ niile re-segmentation.N'otu oge ahụ, usoro COB ọ bụghị nanị na-eweta ikike nchịkwa dị nta, kamakwa ọ na-eweta nkasi obi dị mma na ahụmahụ ntụkwasị obi.
Ka ọ dị ugbu a, teknụzụ MicroLED aghọwo ihe ọzọ na-elekwasị anya na nyocha ihuenyo nnukwu ihuenyo LED.E jiri ya tụnyere ọgbọ gara aga COB usoro obere pixel pitch LEDs, echiche MicroLED abụghị mgbanwe na ntinye ma ọ bụ teknụzụ encapsulation, ma na-emesi ike "miniaturization" nke kristal bead oriọna.
