Kumenyekanisha Isi idasanzwe ya Chip-on-Board (COB) LCDs

Muri rusange, COB LCD irangwa no gushyira mu buryo butaziguye imashini imwe cyangwa nyinshi zuzuzanya (IC) - ubusanzwe umushoferi werekana - ku kirahuri cy'ikirahure cy'ikibaho cya LCD. Uku guhuza bitaziguye kugerwaho binyuze mubikorwa bizwi kwizirika insinga, aho insinga za zahabu cyangwa insinga za aluminiyumu zihuza neza amakariso kuri silicon apfa nudupapuro duhuza ikirahure. Icyakurikiyeho, ibikoresho birinda ibintu, akenshi bikoreshwa na epoxy resin, bikoreshwa mukurinda imiyoboro yoroshye hamwe ninsinga zinsinga zidahungabanya ibidukikije nkubushuhe ningaruka zumubiri. Uku kwishyira hamwe kwabashoferi bazunguruka mu kirahure bitanga uburyo bworoshye kandi bukomeye bwo kwerekana ugereranije nubundi buryo bwo guteranya.

Ingaruka ziyi paradigima yububiko ni nyinshi. Imwe mu nyungu zigaragara zikoranabuhanga rya COB nuburyo bwacyo bukora neza. Mugukuraho ibikenewe byacapwe byumuzunguruko wihariye (PCB) kugirango ube umushoferi IC, modul ya COB yerekana ibirenge byagabanutse cyane. Uku guhuzagurika ni byiza cyane mubikorwa aho umwanya uri murwego rwo hejuru, nk'ikoranabuhanga ryambarwa, ibikoresho byabigenewe, hamwe n’imodoka zimwe na zimwe. Byongeye kandi, inzira zigufi z'amashanyarazi hagati ya chip ya shoferi na LCD panel zigira uruhare mukuzamura ibimenyetso byerekana ibimenyetso no kugabanya amashanyarazi (EMI). Iterambere ryimikorere ryamashanyarazi rirashobora guhindurwa mubikorwa bihamye kandi byizewe byerekana, cyane cyane mubisabwa na electronique.

Indi mico ikomeye ya COB LCDs iri mubukomezi bwayo no kwihanganira ihungabana ryimashini no kunyeganyega. Kwizirika kuri chip kumurongo wikirahure, hamwe no kurinda kurinda, bitanga inteko yumvikana neza ugereranije nubuhanga bushingiye kumasoko yagurishijwe kuri PCB itandukanye. Uku gukomera gukomeye gutuma COB LCDs ihitamo kubisabwa bikorerwa mubikorwa bibi, nkibikoresho bigenzura inganda nibyapa byo hanze. Byongeye kandi, imicungire yubushyuhe buranga COB irashobora kuba ingirakamaro mubihe bimwe. Guhuza bitaziguye hagati ya chip na substrate yikirahure birashobora koroshya gukwirakwiza ubushyuhe, nubwo ibi biterwa cyane nigishushanyo cyihariye nibikoresho byakoreshejwe.

Ariko, nkuburyo ubwo aribwo bwose bwikoranabuhanga, COB LCDs nayo itanga ibitekerezo bimwe. Umugereka wa chip utaziguye ukenera ibikoresho byubuhanga nubuhanga kabuhariwe, birashoboka ko biganisha ku biciro byambere byo gushiraho ugereranije nubundi buryo bwo guterana. Byongeye kandi, gusubiramo cyangwa gusimbuza chip yumushoferi utari mwiza muri module ya COB birashobora kuba ibintu bigoye kandi akenshi bidashoboka. Uku kubura kwishyurwa birashobora kuba ikintu mubisabwa hamwe nibisabwa bikenewe byo kubungabunga. Byongeye kandi, igishushanyo mbonera cya modul ya COB irashobora kugabanywa ugereranije nuburyo bukoresha PCB zitandukanye, aho guhindura no guhindura ibice bishobora gushyirwa mubikorwa byoroshye.

Kugirango urusheho gusobanukirwa neza imiterere yagutse yinteko ya LCD, birakwiye ko dusuzuma ikoranabuhanga rifitanye isano,cyane Chip-on-Glass (COG). Ikibazo "Ni irihe tandukaniro riri hagati ya COB na COG?" bikunze kuvuka mubiganiro bijyanye no kwerekana module yo guhimba. Mugihe COB na COG zombi zirimo guhuza byimazeyo ibiyobora IC kubirahuri, uburyo bukoreshwa buratandukanye cyane. Muri tekinoroji ya COG, umushoferi IC ahujwe neza nikirahure akoresheje firime ya anisotropique (ACF). Iyi ACF ikubiyemo uduce duto duto dushyiraho amashanyarazi hagati ya padi kuri chip hamwe nudupapuro duhuye nikirahure, mugihe utanga amashanyarazi mumurongo utambitse. Bitandukanye na COB, COG ntabwo ikoresha guhuza insinga.

Guhindura iri tandukaniro ryibanze mu buhanga bwo guhuza ni byinshi. Module ya COG mubisanzwe irerekana umwirondoro muto ndetse nuburemere bworoshye ugereranije na COB bagenzi babo, kuko kurandura imigozi y'insinga bituma habaho igishushanyo mbonera. Byongeye kandi, muri rusange COG itanga ihuza ryiza cyane, igafasha kwerekana ibyemezo bihanitse hamwe nubunini bwa pigiseli. Ibi bituma COG ihitamo guhitamo imikorere-yerekana cyane muri terefone zigendanwa, tableti, nibindi bikoresho bya elegitoroniki bigendanwa aho guhuzagurika no kubona ibintu ari byo byingenzi.

Nyamara, tekinoroji ya COG nayo ifite uburyo bwihariye bwo gucuruza. Gahunda yo guhuza ACF irashobora kumva neza ubushyuhe nubushyuhe butandukanye ugereranije na encapsulation ikoreshwa muri COB. Byongeye kandi, ubukanishi bukomeye bwa moderi ya COG burashobora kuba munsi gato ugereranije nubwa COB mubice bimwe na bimwe bihungabana cyane. Igiciro cyo guteranya COG nacyo gishobora kuba hejuru ya COB, cyane cyane kubunini bunini bwo kwerekana no kubara pin.

Kurenga COB na COG, ubundi buhanga bujyanye no kuvuga ni Chip-on-Flex (COF). Muri COF, umushoferi IC ahujwe nuruziga rworoshye (FPC) hanyuma igahuzwa na substrate yikirahure. COF itanga impirimbanyi hagati yubukorikori bwa COG nuburyo bworoshye bwo gushushanya ibisubizo gakondo bya PCB. Bikunze gukoreshwa mubisabwa bisaba kwerekana ibishushanyo byoroshye cyangwa aho imbogamizi zumwanya zikenera guhuza kandi byoroshye.

Muri tekinoroji ya Malio, ibyo twiyemeje gutanga ibisubizo bitandukanye kandi byujuje ubuziranenge byerekana ibisubizo bigaragara mubicuruzwa byacu byuzuye. Urugero, "COB / COG / COF Module, FE ishingiye kuri Amorphous C-Cores"byerekana ubuhanga bwacu mu gukora module dukoresha tekinoroji zitandukanye za chip-on kugira ngo zuzuze ibisabwa byihariye. Muri ubwo buryo."COB / COG / COF Module, FE ishingiye kuri 1K101 Agasanduku ka Amorphous"birashimangira kandi ku buryo butandukanye mu gukoresha ubwo buhanga bwo guterana. Byongeye kandi, ubushobozi bwacu bugera no ku gice cyihariye cya LCD na LCM, nk'uko byagaragajwe n'uruhare rwacu nk'uruhare."Cage Terminal yo gupima LCD / LCM Igice cyerekana Kugaragaza."Izi ngero zerekana ubuhanga bwacu mu kudoda ibisubizo byerekana ibyifuzo byihariye by'inganda zitandukanye.

Mu gusoza, tekinoroji ya Chip-on-Board (COB) LCD yerekana uburyo bwingenzi bwo kwerekana ibihimbano, bitanga inyungu mubijyanye no guhuzagurika, gukomera, no kongera ingufu z'amashanyarazi. Mugihe itanga imbogamizi zijyanye no kwishyurwa no gushushanya ugereranije nubundi buryo nka COG na COF, imbaraga zavukamo zituma ihitamo rikomeye kubikorwa byinshi, cyane cyane bisaba kuramba no gukora neza. Gusobanukirwa nu tekinoroji ya tekinoroji ya COB, hamwe no gutandukanya tekiniki zijyanye nayo, ni ingenzi kubashakashatsi n'abashushanya bashaka guhitamo igisubizo cyiza cyo kwerekana kubyo bakeneye byihariye. Muri Tekinoroji ya Malio, dukomeje kuba ku isonga mu kwerekana udushya twerekana, duha abafatanyabikorwa bacu ubumenyi n’ibicuruzwa bikenewe kugira ngo tumurikire ejo hazaza h’ikoranabuhanga rigaragara.
