Ụlọ ọrụ obere/micro LED na 2024: Akụkọ nke nnukwu akụnụba dị iche n'etiti nnukwu itinye ego （3）
Ngwaahịa COB Na-aga n'ihu Na-achị Ahịa
N'ime ụlọ ọrụ ngosi asọmpi dị elu, ngwaahịa COB na-enwe ọganihu dị egwu. Obere LED, ọdịnihu ya jikọtara nke ọma na Obere LEDỌzọkwa, n'oge ọkwa etiti, COB nwekwara ike iwere ụdị MIP. Na 2024, COB apụtala dị ka ihe ngwọta dị elu - nke zuru oke - na-ebute "echiche mgbanwe" ọhụrụ.
N'otu aka, ihuenyo LED nke dabeere na COB ahụla mbelata ọnụ ahịa dị ukwuu na 2024, si otú a na-enyocha ahịa ọhụrụ na-abawanye. Data ụlọ ọrụ na-egosi na ọnụ ahịa nke ihe ndị e ji ekpuchi COB adaala site na yuan 48,000 kwa square mita (agbakọ na P1.25) na 2018 ruo yuan 9,000 kwa square mita na 2024. Na 2024, e nwere mbelata ọnụahịa kwa nkeji atọ nke pasentị 3 - 5. Mbelata ọnụahịa a emeela ka ndị ahịa gbasaa maka ngwaahịa COB dị elu, nke na-akpali uto nke nha ahịa ya.
N'aka nke ọzọ, ụdị ngwaahịa COB dị iche iche amụbaala. Mmụba nke ngwaahịa dịka COB na-abawanye. Obere LEDkristal mmiri mmiri ọkụ azụ, COB - MIPngwaahịa, COB - Obere LEDngwaahịa, na ngwaahịa COB dị na nkọwapụta P0.7/P1.5/P1.8 emeela ka ahịa ahịa gbasaa nke ukwuu. Nke a abụghị naanị na ọ gbasaara ahịa teknụzụ COB n'ime ụlọ ọrụ ngosi kamakwa ọ mụbara ụdị na nha nke ndị ahịa, na-eme ka mmepe nke COB dịkwuo ngwa ngwa.
Ka ọchịchọ maka ngwaahịa COB na-arị elu, ndị na-emepụta ihe n'ụlọ ọrụ na-amụba ikike mmepụta. Dịka ọmụmaatụ, ikike mmepụta COB nke Zhaochi Co., Ltd. erughi mita square 10,000 na 2022, mana ka ọ na-erule Ọktoba 2024, ọ mụbara ruo mita square 20,000. Ike mmepụta COB nke Unilumin Technology mụbara nke ukwuu ruo 4000KK/ọnwa na 2024. Dr. Shao Pengrui, osote onye njikwa izugbe nke Asmade Zhuoxing Semiconductor, buru amụma na ka ọ na-erule 2028, mpaghara ikike mmepụta kwa afọ nke COB ga-eru mita square 500,000, nke okpukpu 7-8 karịa nke ọkwa ugbu a.
Banyere mmepe teknụzụ nke COB, ụlọ ọrụ ahụ kwenyere na nnukwu mbufe na Obere LEDbụ teknụzụ abụọ dị mkpa na-akwado ya. Mmụba nke ahịa obere pitch na ultra-micro-pitch, yana nkwalite nke obere pitch LED nkịtị ruo na ihe achọrọ maka nkọwa dị elu na nke dị elu-dị elu, bụ isi ihe na-akpali ndị ahịa. N'ihi ọnọdụ a, ọ dịghị ihe mere a ga-eji leda teknụzụ COB anya n'oge MIP. Ọzọkwa, ngwaahịa MIP dị elu - obere - pitchnwekwara ike iji ngwọta nkwakọ ngwaahịa nke abụọ nke COB.
N'okpuru ụkpụrụ ahụ bụ "ihe kachasị elu, ihe ka mma, ma dabere na ya obere LEDsna obere ngwaọrụ ndị bụ isi, otú ahụ ka COB ga-esi na-ewu ewu", COB ga-anọgide na-abụ isi okwu na-akpali akpali na Ụlọ ọrụ LED dị obere/mikro.
