Muri rusange, tekinoroji ya COB, nkuko ikoreshwa kuri LCDs, ikubiyemo kwomeka mu buryo butaziguye umuzenguruko uhuriweho (IC) ugenga imikorere yerekana ku kibaho cyacapwe (PCB), hanyuma kigahuzwa na LCD panel ubwayo. Ibi bihabanye cyane nuburyo bwa gakondo bwo gupakira, akenshi bikenera ibinini binini, bigoye cyane. Ubuhanga bwa COB buri mubushobozi bwayo bwo koroshya inteko, guteza imbere module yerekana kandi yoroheje. Silicon yambaye ubusa ipfa, ubwonko bwo kwerekana, ihujwe neza na PCB, hanyuma igashyirwa hamwe na resin ikingira. Uku kwishyira hamwe ntigukomeza gusa umutungo wimitungo utimukanwa gusa ahubwo binashimangira imiyoboro yamashanyarazi, biganisha ku kwizerwa no kuramba kuramba.
Ibyiza bitangwa na COB LCDs ni byinshi kandi birakomeye. Ubwa mbere, ibyabobyongerewe ubwizerweni ingaruka zitaziguye zishushanyije. Mugabanye ibice bitandukanijwe hamwe nu nsinga zo hanze, ibyoroshye kunanirwa guhuza biragabanuka cyane. Uku gukomera gukomeye gutuma COB LCDs ikwiranye cyane na porogaramu isaba imikorere idahwitse mubidukikije bigoye, nkibikoresho bikoresha ibinyabiziga cyangwa sisitemu yo kugenzura inganda zikomeye. Umugereka utaziguye ugabanya intege nke akenshi zijyanye no guhuza kwinshi, bitanga igisubizo cyerekana gishobora kwihanganira ibintu byinshi bihindagurika hamwe nubushyuhe bwumuriro.
Icya kabiri,umwanya mwizani ikiranga tekinoroji ya COB. Mubihe ibikoresho bya elegitoronike bigenda bigabanuka, milimetero zose zifite agaciro. COB LCDs, hamwe nibirenge byayo byagabanutse, yemerera gukora ibicuruzwa byoroshye, byoroheje bitabangamiye imikorere. Ubu bwitonzi bworoshya inzira yo guterana, bugira uruhare mukugabanya inganda zinganda kandi, mugihe cyagutse, ibiciro byumusaruro. Kwishyira hamwe bibohora abashushanya imbogamizi za bulkier zisanzwe modules, gufungura vista nshya yo gushushanya ibicuruzwa no gutwara ibintu. Kurugero, Malio, vanguard mugaragaza ibisubizo, itanga aCOB LCD Module(P / N MLCG-2164). Iyi module yihariye irerekana umwanya-wo kubika ibiranga COB, itanga amakuru yuzuye yo kureba ahantu hagaragara muburyo bufatika, bukwiranye nuburyo bugari bwibisabwa bisaba ibishushanyo mbonera byerekana imiterere.
Byongeye kandi, COB LCDs yerekana ibintu bigaragaragukoresha ingufu. Ibikoresho bya chip byashyizwe ahagaragara kandi bigabanya ingufu z'amashanyarazi zigaragara mubishushanyo byazo bigira uruhare mu gukoresha ingufu nke, ikintu gikomeye kubikoresho bikoreshwa na bateri na sisitemu ziharanira gukora birambye. Gucunga neza amashyuza nibindi byiza byimbere. Igishushanyo cyorohereza ikwirakwizwa ryubushyuhe butangwa mugihe gikora murwego rwo hejuru, akenshi byongerwaho nubushyuhe bwuzuye, bityo bikongerera igihe cyo kwerekana no kwirinda kwangirika kwubushyuhe. Ubu buhanga bwitondewe bwemeza ko no mubikorwa bikomeza, kwerekana kwerekana imikorere myiza utiriwe utwarwa nubushyuhe buterwa nubushyuhe.
Ubwinshi bwa COB LCDs bugaragazwa no kwakirwa kwabo mubice bitandukanye. Mu rwego rwibikorwa byubwenge, MalioIgice LCD Yerekana COB Module kubipimo by'amashanyaraziihagaze nkurugero rwibanze. Izi modules zakozwe muburyo bwihariye kugirango zisobanuke, zirata ikigereranyo kinini cyerekana itandukaniro ryemeza ko byemewe nubwo haba hari izuba ryinshi - ikintu cyingenzi muburyo bwo gupima hanze cyangwa igice cyo hanze. Gukoresha ingufu nke hamwe no kuramba kwabo birashimangira ko bikwiranye nibikoresho remezo-bikomeye. Usibye ibikorwa byingirakamaro, COB LCDs isanga métier yabo mubikoresho byubuvuzi, nka oximeter hamwe nibikoresho bya X-ray, aho kwizerwa kutajegajega no kubona amakuru neza bidashoboka. Porogaramu zikoresha ibinyabiziga nazo zikoresha COB kuri disikuru yerekana na sisitemu ya infotainment, byunguka imbaraga zabo kandi bigaragara neza. Ndetse no mumashini yinganda, aho kwerekana bihanganira imikorere mibi, COB LCDs itanga ibitekerezo byizewe.
COB na COG: Ihuriro rya Filozofiya Yashushanyije
Gusobanukirwa neza kubijyanye no kwerekana tekinoroji akenshi bisaba gushushanya itandukaniro hagati yuburyo busa. Muri disikuru yo kwerekana kwishyira hamwe, amagambo abiri ahinnye aravuka: COB (Chip-on-Board) naCOG (Chip-on-Glass). Mugihe byombi bigamije kugabanya no kuzamura imikorere yerekana, ibyubatswe byubatswe byubaka biganisha ku nyungu zitandukanye hamwe nibisabwa.
Itandukaniro ryibanze riri muri substrate umushoferi IC yashizwemo. Nkuko byasobanuwe, tekinoroji ya COB yinjiza IC kuri PCB, hanyuma igahuza na LCD. Ibinyuranye, tekinoroji ya COG irenga PCB gakondo yose, igashiraho umushoferi IC kumurongo wikirahure cyumwanya wa LCD. Uku guhuza bitaziguye na IC kubirahuri bivamo ndetse birushijeho kuba byoroshye kandi byoroshye, bigatuma COG ihitamo cyane kubikoresho aho ubunini bukabije nuburemere buke aribwo bwambere, nka terefone zigendanwa, amasaha yubwenge, nibindi bikoresho bya elegitoroniki byoroshye.
Uhereye ku gishushanyo n'ubunini, COG LCDs isanzwe ifite umwirondoro woroshye kubera kubura PCB itandukanye. Ihuriro ritaziguye ryerekana ubujyakuzimu bwa module, byorohereza ibicuruzwa byoroshye. COB, nubwo ikiri nto cyane ugereranije nikoranabuhanga rya kera, igumana ubworoherane butangwa na PCB, itanga uburyo bukomeye kandi bwihariye. Ibi birashobora kubamo gushyiramo ibice byongeweho cyangwa uruziga rugoye kurubaho, bishobora kuba byiza kubisabwa byihariye bisaba ubwenge bunini bwo mu bwato cyangwa kwishyira hamwe.
Kubireba imikorere nigihe kirekire, tekinoroji zombi zitanga kwizerwa cyane. Nyamara, COG LCDs, bitewe no kugira aho uhurira (IC ku kirahure), rimwe na rimwe irashobora kwerekana umurongo uramba mugihe cyubwoko bumwe na bumwe bwo guhangayika. Ibinyuranye, COB LCDs, hamwe na IC yashyizwe neza kuri PCB ihamye kandi ikomatanyirijwe hamwe, akenshi itanga urubuga rukomeye rwo gukora sisitemu rusange, cyane cyane aho kurwanya ibinyeganyega cyangwa ingaruka ari ikibazo cyibanze. Igice cyo gusana nacyo kiratandukanye; mugihe moderi ya COG izwiho gusana bitewe nubusabane butaziguye ku kirahure, modul ya COB, hamwe na IC kuri PCB itandukanye, irashobora gutanga inzira yoroshye yo gusana no guhindura inzira.
Ibiciro byigiciro nabyo birerekana dicotomy. Kubyinshi cyane mubyakozwe muburyo busanzwe, tekinoroji ya COG irashobora kwerekana ko ihenze cyane kubera uburyo bworoshye bwo guterana no kugabanya imikoreshereze yibikoresho mugihe kirekire. Nyamara, kubisabwa bisaba kwihindura cyangwa kugabanuka kwijwi, tekinoroji ya COB akenshi itanga imbaraga zubukungu, kuko ikiguzi cyibikoresho byabigenewe bya COG birashobora kubuzwa. Ubuhanga bwa Malio bugera noLCD / LCM Igice cyerekana Kugereranya, gutanga ubwinshi bwamahitamo yihariye arimo ubwoko bwa LCD, ibara ryinyuma, uburyo bwo kwerekana, hamwe nubushyuhe bwo gukora. Uku guhindagurika muburyo bwo kudoda ibisubizo byerekana uburyo bwo guhuza n'ikoranabuhanga nka COB muguhuza ibisabwa bespoke, aho ubushobozi bwo guhindura igishushanyo cya PCB ari ntagereranywa.
Guhitamo hagati ya COB na COG amaherezo bishingiye kubikorwa byihariye bya porogaramu. Kubishushanyo bishyira imbere kunanuka kwinshi hamwe nubunini buke bwa elegitoroniki, COG akenshi ifata umwanya wambere. Nyamara, kubisabwa bisaba kuringaniza imikorere ikomeye, gushushanya byoroshye, kandi akenshi birenze ubushobozi bwa electronique, COB ikomeza guhitamo bidasanzwe. Ubushobozi bwayo bwo gushyigikira uruziga rugoye kuri PCB ihuriweho bituma itagira agaciro kubikoresho byinganda, ibinyabiziga, nibikoresho byihariye.
Ibihe bizaza byerekanwe hamwe
Ubwihindurize bwa tekinoroji yerekana ni ugukurikirana bidasubirwaho ibisubizo binini, byongeweho gusobanuka, no kugabanya ibintu bifatika. Tekinoroji ya COB LCD, hamwe nibyiza byayo, yiteguye gukomeza kuba umukinnyi wingenzi muri iri terambere rikomeje. Iterambere rihoraho mubikoresho bya ensapsulation, tekinike yo guhuza, hamwe na IC miniaturisation bizarushaho kunonosora modul ya COB, bigasunika imipaka y'ibishoboka muguhuza kwerekanwa.
Ubushobozi bwo gupakira ibice byinshi, bikavamo "ultra-micro pitch" kwerekana, bizatanga ecran hamwe nubushishozi butagereranywa bwo kubona no kutagira ikinyabupfura. Ubu bucucike kandi bugira uruhare mu kugereranya itandukaniro, kuko kutagira ibintu bisanzwe bipakira bigabanya urumuri kandi bikongerera ubujyakuzimu bwabirabura. Ikigeretse kuri ibyo, kuramba kuramba no gucunga neza amashyanyarazi yububiko bwa COB bituma baba abakandida beza kubigaragaza byerekana porogaramu, harimo guhinduka ndetse no kwerekana mu mucyo, aho uburyo gakondo burwanira guhaza ibyifuzo byumubiri.
Malio, hamwe nubushake bwayo bwo kwerekana ibisubizo bigezweho, ihora ishakisha iterambere. Urutonde rwibicuruzwa bya COB, kuva murwego rwohejuru rwerekana ibishushanyo mbonera kugeza kubice byihariye byerekana ibikoresho bikomeye, bishimangira ubuhanga bwabo mugukoresha ubwo buryo bwikoranabuhanga. Nta gushidikanya ko ejo hazaza hazaba COB LCDs ku isonga mu gushushanya ibicuruzwa bishya, byorohereza imiterere igaragara, iramba, kandi ikoresha ingufu mu mashusho mu nganda.
