Kutheyiphu eguqukayo njalo yobuchwepheshe bokubonisa, izibonisi ze-liquid crystal (LCDs) zimi njengabo balindi abatholakala yonke indawo, zikhanyisa yonke into kusukela kumadivayisi ethu aphathwayo kuya kuzimpawu zedijithali ezimangalisayo. Ngaphakathi kwalo mhlaba ohlukahlukene, indlela yokwenza okuthile, eyaziwa ngokuthi i-Chip-on-Board (COB), ibambe isikhundla esibalulekile, nakuba ngokuvamile sibukelwa phansi. Kwa-Malio Technology, sihlala silwela ukucacisa ubunkimbinkimbi bobuchwepheshe bokubonisa, sinikeza amakhasimende ethu amandla okuqonda okujulile kwezingxenye ezisekela ukusungulwa kwawo. Lokhu kuveza kuhlolisisa izimiso eziyisisekelo ze-COB LCDs, ihlola ukwakheka kwayo, izinzuzo zayo, kanye nokwehlukaniswa kobuchwepheshe obuhlobene.
Ngomqondo wayo oyisisekelo, i-COB LCD ibonakala ngokunamathiselwa okuqondile kwe-chip eyodwa noma amaningi wesekethe ehlanganisiwe (IC) - ngokuvamile umshayeli wesibonisi - ku-substrate yengilazi yephaneli ye-LCD. Lokhu kubopha okuqondile kufinyelelwa ngenqubo eyaziwa ngokuthi i-wire bonding, lapho izintambo ezincane zegolide noma ze-aluminium zixhuma ngokucophelela amaphedi ku-silicon die namaphedi ahambisanayo engilazini. Kamuva, i-encapsulant evikelayo, ngokuvamile eyi-epoxy resin, isetshenziswa ukuze kuvikelwe i-chip entekenteke nezibopho zezintambo ezicindezelweni zemvelo ezinjengomswakama nomthelela womzimba. Lokhu kuhlanganiswa kokujikeleza komshayeli ngqo engilazini kuveza imojuli yokubonisa ehlangene futhi eqinile uma kuqhathaniswa nezinye izindlela zokuhlanganisa.
Imithelela yale paradigm yezakhiwo miningi. Enye yezinzuzo ezibaluleke kakhulu zobuchwepheshe be-COB ukusebenza kahle kwayo kwesikhala. Ngokuqeda isidingo sebhodi lesifunda eliphrintiwe elihlukile (PCB) ukuze lifake ama-ICs omshayeli, amamojula e-COB abonisa unyawo oluncishiswe kakhulu. Lokhu kubumbana kunenzuzo ikakhulukazi ezinhlelweni lapho isikhala siphezulu kakhulu, njengobuchwepheshe obugqokekayo, amathuluzi aphathwayo, nezibonisi ezithile zezimoto. Ngaphezu kwalokho, izindlela zikagesi ezifushanisiwe phakathi kwe-chip yomshayeli nephaneli ye-LCD zinomthelela ekuthuthukisweni kobuqotho besignali kanye nokunciphisa ukuphazamiseka kwe-electromagnetic (EMI). Lokhu kusebenza kukagesi okuthuthukisiwe kungahumushela ekusebenzeni kwesibonisi okuzinzile futhi okuthembekile, ikakhulukazi ezindaweni ezidinga uzibuthe kagesi.
Esinye isici esiphoqelelayo sama-COB LCDs sisekuqineni kwawo nasekuqineni kokushaqeka kwemishini nokudlidliza. Ukunamathiselwa okuqondile kwe-chip ku-substrate yengilazi, kuhlanganiswe ne-encapsulation yokuvikela, kunikeza umhlangano ozwakalayo wesakhiwo uma kuqhathaniswa namasu ancike ekuxhumekeni okudayisiwe ku-PCB ehlukile. Lobu bunzima bemvelo benza i-COB LCDs ibe inketho ekhethwayo yezinhlelo zokusebenza ezingaphansi kwezimo zokusebenza ezinzima, njengamaphaneli okulawula ezimbonini nezimpawu zangaphandle. Ngaphezu kwalokho, izici zokuphatha ezishisayo ze-COB zingaba wusizo ezimeni ezithile. Ukuxhumana okuqondile phakathi kwe-chip ne-substrate yengilazi kungenza kube lula ukuchithwa kokushisa, nakuba lokhu kuncike kakhulu kumklamo othize nezinto ezisetshenziswayo.
Kodwa-ke, njenganoma iyiphi indlela yobuchwepheshe, ama-COB LCDs nawo aveza ukucatshangelwa okuthile. Ukunamathiselwe kwe-chip eqondile kudinga amathuluzi okukhiqiza akhethekile nobungcweti, okungase kuholele ezindlekweni zokusetha eziphakeme uma kuqhathaniswa nezinye izindlela zokuhlanganisa. Ngaphezu kwalokho, ukulungisa kabusha noma ukushintshwa kwe-chip yomshayeli enephutha kumojula ye-COB kungaba umsebenzi oyinkimbinkimbi futhi ovame ukungenzeki. Lokhu kuntuleka kokulungiseka kungaba isici kuzinhlelo zokusebenza ezinezidingo eziqinile zokunakekela. Ukwengeza, ukuguquguquka kokuklama kwamamojula we-COB kungabambezeleka ngandlela thize uma kuqhathaniswa nezindlela ezisebenzisa ama-PCB ahlukene, lapho ukuguqulwa noshintsho lwengxenye kungenziwa kalula.
Ukuze uthole ukuqonda okubanzi kwendawo ebanzi yomhlangano wemojula ye-LCD, kubalulekile ukucabangela ubuchwepheshe obuhlobene,ikakhulukazi i-Chip-on-Glass (COG). Umbuzo othi "Uyini umehluko phakathi kwe-COB ne-COG?" kuvame ukuvela ezingxoxweni eziphathelene nokwakhiwa kwemojula yesibonisi. Nakuba kokubili i-COB ne-COG kuhilela ukunamathiselwa okuqondile kwama-ICs omshayeli ku-substrate yengilazi, indlela yokusebenza esetshenziswayo ihluka kakhulu. Kubuchwepheshe be-COG, umshayeli we-IC uboshelwe ngqo engilazini esebenzisa ifilimu ye-anisotropic conductive (ACF). Le ACF iqukethe izinhlayiya eziqhubayo ezisungula ukuxhumana kukagesi phakathi kwamaphedi ku-chip namaphedi ahambisanayo engilazini, kuyilapho ihlinzeka ngokufakwa kukagesi endizeni evundlile. Ngokungafani ne-COB, i-COG ayisebenzisi i-wire bonding.
Imiphumela yalo mehluko oyisisekelo kubuchwepheshe bokubambisana mikhulu. Amamojula e-COG ngokuvamile abonisa iphrofayela encane nakakhulu nesisindo esilula uma kuqhathaniswa nozakwabo be-COB, njengoba ukuqedwa kwamabhondi ezintambo kuvumela idizayini ehleleke kakhudlwana. Ngaphezu kwalokho, i-COG ngokuvamile inikezela ngoxhumano lwephimbo elingcono, okuvumela ukulungiswa okuphezulu kwesibonisi kanye nokuminyana kwamaphikseli okukhulu. Lokhu kwenza i-COG ibe inketho ekhethwayo yezibonisi ezisebenza kahle kakhulu kuma-smartphone, amathebulethi, nezinye izinto zikagesi eziphathwayo lapho ukubumbana nokuhlakanipha kokubukwa kubaluleke kakhulu.
Kodwa-ke, ubuchwepheshe be-COG nabo bunesethi yabo yokuhwebelana. Inqubo yokuhlanganisa i-ACF ingazwela kakhulu ekuhlukeni kwezinga lokushisa nokuswakama uma kuqhathaniswa ne-encapsulation esetshenziswa ku-COB. Ukwengeza, ukuqina kwemishini kwamamojula we-COG kungase kube ngaphansi kancane kunamamojula e-COB ezindaweni ezithile ezithuthumela kakhulu. Izindleko zokuhlanganisa i-COG nazo zingaba phezulu kune-COB, ikakhulukazi osayizi abakhulu bokuboniswa nokubala kwamaphinikhodi aphezulu.
Ngale kwe-COB ne-COG, obunye ubuchwepheshe obuhlobene okufanele bubalulwe yi-Chip-on-Flex (COF). Ku-COF, i-IC yomshayeli iboshelwa kusekethe ephrintiwe eguquguqukayo (FPC) ebese ixhunywa ku-substrate yengilazi. I-COF inikeza ibhalansi phakathi kokubumbana kwe-COG kanye nokuguquguquka kwedizayini yezixazululo zendabuko ezifakwe ku-PCB. Ivamise ukusetshenziswa ezinhlelweni ezidinga imiklamo yesibonisi evumelana nezimo noma lapho izithiyo zesikhala zidinge ukuxhuma okuncanyana nokugobekayo.
Kwa-Malio Technology, ukuzibophezela kwethu ekunikezeni izixazululo zokubonisa ezihlukahlukene nezisezingeni eliphezulu kubonakala kuphothifoliyo yethu yomkhiqizo obanzi. Ngokwesibonelo, yethu "I-COB/COG/COF Module, i-FE-based Amorphous C-Cores"isibonelo sobuchwepheshe bethu bokwenza amamojula asebenzisa ubuchwepheshe obuhlukahlukene ukuze kuhlangatshezwane nezidingo ezithile zohlelo lokusebenza. Ngokufanayo, "Imojula ye-COB/COG/COF, i-FE-based 1K101 Amorphous Ribbon" igcizelela futhi ukuguquguquka kwethu ekusebenziseni lezi zindlela zokuhlanganisa ezithuthukisiwe. Ngaphezu kwalokho, amandla ethu adlulela kuzibonisi zengxenye ze-LCD neze-LCM ezenziwe ngezifiso, njengoba kugqanyiswe indima yethu "Itheminali Yekheji Yokukala Ukubonisa Ngokwezifiso Ingxenye Ye-LCD/LCM Yokulinganisa."Lezi zibonelo zibonisa ubungcweti bethu bokwenza izixazululo zokubonisa ezidingweni ezihlukile zezimboni ezahlukahlukene.
Sengiphetha, ubuchwepheshe be-LCD be-Chip-on-Board (COB) bumele indlela ebalulekile yokubonisa ukwenziwa kwemojuli, enikeza izinzuzo mayelana nokubumbana, ukuqina, kanye nokusebenza kukagesi okungenzeka kuthuthukiswe. Nakuba yethula imikhawulo ethile mayelana nokulungiseka futhi nokuguquguquka komklamo uma kuqhathaniswa nezinye izindlela ezifana ne-COG ne-COF, amandla ayo emvelo ayenza ibe ukukhetha okuphoqelelayo kuhlu olubanzi lwezinhlelo zokusebenza, ikakhulukazi lezo ezidinga ukuqina nokusebenza kahle kwendawo. Ukuqonda ama-nuances wobuchwepheshe be-COB, kanye nokwehluka kwawo kumasu ahlobene, kubalulekile konjiniyela nabaklami abafuna ukukhetha isixazululo esifanelekile sokubonisa ngezidingo zabo ezithile. Kwa-Malio Technology, sihlala sihamba phambili ekuboniseni izinto ezintsha, sinikeza ozakwethu ulwazi nemikhiqizo edingekayo ukuze sikhanyisele ikusasa lobuchwepheshe obubonakalayo.
