Muva nje, ingxenye ye-B2B yenkampani enkulu yomkhiqizo ikhiphe isizukulwane esisha sochungechunge lwemephu yenkanyezi ye-COB yesikhala esincane.Usayizi we-chip ye-LED ekhipha ukukhanya komkhiqizo ngu-70μm kuphela, futhi indawo yephikseli encane kakhulu ekhipha ukukhanya ithuthukisa ukugqama.
Eqinisweni, bonke abakhiqizi abakhulu bakhulisa i-R&D yabo kanye nokuqamba okusha kobuchwepheshe be-COB futhi babamba imakethe.Kodwa-ke, ngaphezu kokuvumelana kokuthi "i-COB iyindlela ephezulu yokugcina ephezulu yobuchwepheshe bokupakisha", kusenomehluko omkhulu kubuchwepheshe be-MiP ne-COB embonini.
Ukwahlulela kwemizila yezobuchwepheshe yesikhathi eside neyesikhashana
Njengoba i-COB inweba ifinyelela kuma-pitches amakhulu futhi i-MiP isondela ezindaweni ezincane, nakanjani kuzoba nezinga elithile lokuncintisana phakathi kwemizila emibili yobuchwepheshe.Kodwa njengamanje, akubona ubuhlobo obuhlukile bokuphila noma ukufa.Ngakho-ke, phakathi nenkathi ethile yesikhathi nangaphakathi kwebanga elithile, i-COB, i-MiP, ne-IMD zizohlala ndawonye.Lezi zonke izinqubo ezidingekayo zokuthuthukiswa kobuchwepheshe.
Ngokombono wesikhathi eside, i-COB manje isisungule inzuzo ebalulekile yokuqala, futhi izinkampani nemikhiqizo ingene ngokugcwele emakethe;ngaphezu kwalokho, i-COB inezici zemvelo zezixhumanisi zenqubo ezimfushane nezilula;lapho izinqubo zokudlulisa abantu abaningi Ngemva kokuzuza impumelelo ngokwenani nezindleko, kukhona ithuba lokunqoba amadolobha nezindawo.
Emakethe yamanje, izikrini ezinkulu ezinencazelo ephezulu zisebenzisa imikhiqizo eminingi ye-LED enezikhala ezincane (ngezansi kwe-P2.5).Ngokuzayo, izoqhubeka nokuthuthukela ekukhuleni kwamaphikseli aphezulu kanye nokuphakama kwephikseli encane, okuzokhuthaza i-COB ukuthi ibe isiqondiso esibalulekile sokuthuthukiswa nokuguqulwa kobuchwepheshe bokupakisha be-LED.
Isimo sokuthuthukiswa kwe-COB nezici
Ngokusho kwedatha evela enkampanini yolwazi egunyaziwe, engxenyeni yokuqala ka-2023, ukuthengiswa kwezibonisi ze-LED ze-pitch encane ezweni laseChina kufinyelele ku-7.33 billion, ukunyuka okuncane ngo-0.1% unyaka nonyaka;indawo yokuthunyelwa kwempahla ifinyelele ku-498,000 square metres, ukukhuphuka konyaka nonyaka ngama-20.2%.Phakathi kwazo, nakuba ubuchwepheshe be-SMD (kuhlanganise ne-IMD) buyinto evamile, isabelo sobuchwepheshe be-COB siyaqhubeka sikhula.Ngekota yesibili ka-2023, ingxenye yokuthengisa isifinyelele ku-10.7%.Isabelo semakethe sisonke engxenyeni yokuqala yonyaka senyuke cishe ngamaphesenti ama-3 uma kuqhathaniswa nesikhathi esifanayo.
Njengamanje, imakethe yomkhiqizo yobuchwepheshe be-COB ebonisa i-LED encane iveza izici ezilandelayo:
Inani: Intengo emaphakathi yawo wonke umshini yehle yaba ngaphansi kuka-50,000 yuan/㎡.Izindleko zobuchwepheshe bokupakisha be-COB zehle kakhulu, kangangokuthi intengo yemakethe emaphakathi yemikhiqizo ye-COB yokubonisa ye-LED encane nayo yehle kakhulu kunangaphambili.Engxenyeni yokuqala ka-2023, intengo yemakethe yehle ngo-28%, yafinyelela inani elimaphakathi lama-yuan/㎡ angu-45,000.
Isikhala: Gxila ku-P1.2 nangaphansi kwemikhiqizo.Uma iphuzu lephoyinti lingaphansi kwe-P1.2, ubuchwepheshe bokupakisha be-COB bunenzuzo kuzo zonke izindleko zokukhiqiza;I-COB yenza ngaphezu kuka-60% wemikhiqizo enezingqimba ze-P1.2 nangaphansi.
Isicelo: ikakhulukazi ukuqapha izimo, ezidingeka kakhulu emikhakheni yobungcweti.Isibonisi esincane se-LED sobuchwepheshe be-COB sinezici zokuminyana okuphezulu, ukukhanya okuphezulu, nokucaca okuphezulu.Ezimeni zokuqapha, ukuthunyelwa kwe-COB kubalwa ngaphezu kwama-40%;zisekelwe ikakhulukazi ezidingweni zamakhasimende emikhakheni yobungcweti, okuhlanganisa amandla edijithali, ezokuthutha, ezempi, ezezimali nezinye izimboni.
Isibikezelo: Ngo-2028, i-COB izoba ngaphezu kwama-30% ama-LED anephimbo elincane
Ukuhlaziywa okuphelele kukhombisa ukuthi njengoba ubuchwepheshe bokupakisha be-COB benza ukusebenzisana okuhle ezicini ezintathu: inqubekelaphambili yobuchwepheshe bezimboni, ukwanda kwamandla okukhiqiza kanye nokwanda kwesidingo semakethe, kancane kancane kuzoba umkhuba obalulekile wobuchwepheshe bomkhiqizo ekuthuthukisweni kwe-micro-pitch ku-LED-pitch encane. imboni yokubonisa.
Ngo-2028, ubuchwepheshe be-COB buzobala ngaphezu kwama-30% okuthengiswayo emakethe yokubonisa yaseChina ye-pitch encane (ngaphansi kwe-P2.5).
Ngokombono webhizinisi, izinkampani eziningi ezibandakanyekayo ekubonisweni kwe-LED azigxili endleleni eyodwa kuphela.Ngokuvamile benza inqubekelaphambili kuzo zombili izikhombisi-ndlela ze-COB ne-MiP.Ngaphezu kwalokho, njengenkambu yezimboni edinga ukutshalwa kwezimali kanye nezobuchwepheshe, ukuvela kwemboni yokubonisa i-LED ayilandeli ngokuphelele isimiso sokusebenza kuqala sokuthi "imali enhle ixosha imali embi".Isimo sengqondo namandla enkambu yebhizinisi kungase futhi kuthinte ikusasa ezimbili Ukuthuthukiswa kwemizila yezobuchwepheshe.
