Nyob rau hauv ib puas-evolving tapestry ntawm zaub technology, kua siv lead ua zaub (LCDs) sawv li ubiquitous sentinels, illuminating txhua yam ntawm peb handheld pab kiag li lawm rau gargantuan digital signage. Hauv cov toj roob hauv pes no, ib txoj kev tsim tshwj xeeb, hu ua Chip-on-Board (COB), tuav txoj haujlwm tseem ceeb, txawm hais tias feem ntau tsis tau hais, qhov tseem ceeb. Ntawm Malio Technology, peb pheej siv zog los piav qhia qhov tsis sib xws ntawm cov thev naus laus zis, txhawb nqa peb cov neeg siv khoom nrog kev nkag siab zoo ntawm cov khoom uas txhawb nqa lawv cov kev tsim kho tshiab. Qhov kev nthuav qhia no delves rau hauv cov ntsiab lus tseem ceeb ntawm COB LCDs, tshawb txog lawv cov architecture, qhov zoo, thiab kev sib txawv ntawm cov thev naus laus zis.
Ntawm nws cov ntsiab lus tseem ceeb, COB LCD yog tus cwj pwm los ntawm kev sib txuas ncaj qha ntawm ib lossis ntau qhov sib xyaw ua ke (IC) chips - feem ntau cov neeg tsav tsheb pom - mus rau iav substrate ntawm LCD vaj huam sib luag. Qhov kev sib txuas ncaj qha no tau ua tiav los ntawm cov txheej txheem hu ua hlau sib txuas, nyob rau hauv minuscule kub los yog txhuas cov xov hlau meticulously txuas cov ntaub qhwv ntawm silicon tuag rau cov khoom siv hluav taws xob sib txuas ntawm lub khob. Tom qab ntawd, ib qho kev tiv thaiv encapsulant, feem ntau yog epoxy resin, yog siv los tiv thaiv qhov muag nti thiab xaim daim ntawv cog lus los ntawm ib puag ncig kev ntxhov siab xws li ya raws thiab lub cev. Qhov kev sib koom ua ke ntawm tus neeg tsav tsheb circuitry ncaj qha mus rau lub iav ua rau muaj kev sib txuam ntau dua thiab muaj zog ua haujlwm zoo piv rau lwm txoj kev sib dhos.
Cov kev cuam tshuam ntawm lub architectural paradigm no yog manifold. Ib qho txiaj ntsig tseem ceeb tshaj plaws ntawm COB thev naus laus zis yog nws qhov chaw ua haujlwm tau zoo. Los ntawm kev tshem tawm qhov xav tau ntawm cov ntawv luam tawm sib cais (PCB) los ua lub tsev tsav tsheb ICs, COB modules pom qhov txo qis hneev taw. Qhov compactness no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov ntawv thov uas qhov chaw nyob ntawm tus nqi, xws li cov cuab yeej siv tau, cov cuab yeej siv tes tuav, thiab qee cov khoom siv tsheb. Tsis tas li ntawd, txoj hauv kev luv luv ntawm cov tsav tsheb nti thiab LCD vaj huam sib luag ua rau muaj kev txhim kho cov teeb liab kev ncaj ncees thiab txo cov hluav taws xob cuam tshuam (EMI). Qhov kev ua tau zoo ntawm hluav taws xob tuaj yeem txhais tau rau kev ua haujlwm ruaj khov thiab txhim khu kev qha, tshwj xeeb tshaj yog nyob rau hauv qhov xav tau ntawm qhov chaw electromagnetic.
Lwm tus cwj pwm tseem ceeb ntawm COB LCDs yog nyob rau hauv lawv cov robustness thiab resilience rau mechanical shock thiab vibration. Kev txuas ncaj qha ntawm cov nti rau cov iav substrate, ua ke nrog kev tiv thaiv encapsulation, muab lub suab sib dhos ntau dua piv rau cov tswv yim uas vam khom kev sib txuas rau ib qho PCB cais. Qhov no ruggedness ua rau COB LCDs yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas raug rau kev ua haujlwm hnyav, xws li kev lag luam tswj vaj huam sib luag thiab kos npe sab nraum zoov. Ntxiv mus, cov yam ntxwv tswj thermal ntawm COB tuaj yeem ua tau zoo hauv qee qhov xwm txheej. Kev sib cuag ncaj qha ntawm cov nti thiab cov iav substrate tuaj yeem ua kom yooj yim rau cov cua sov, txawm tias qhov no yog nyob ntawm qhov tsim tshwj xeeb thiab cov khoom siv ua haujlwm.
Txawm li cas los xij, zoo li txhua txoj hauv kev thev naus laus zis, COB LCDs kuj nthuav qhia qee yam kev xav. Kev sib txuas ncaj nraim yuav tsum muaj cov cuab yeej tsim khoom tshwj xeeb thiab kev txawj ntse, uas ua rau muaj kev teeb tsa ntau dua piv rau lwm txoj hauv kev sib dhos. Tsis tas li ntawd, rov ua dua lossis hloov cov tsav tsheb tsis zoo hauv COB module tuaj yeem yog qhov nyuaj thiab feem ntau ua haujlwm tsis zoo. Qhov tsis muaj kev rov ua dua tshiab no tuaj yeem yog qhov tseem ceeb hauv kev siv nrog kev saib xyuas nruj. Tsis tas li ntawd, kev tsim qauv yooj yim ntawm COB modules tuaj yeem raug txwv me ntsis piv rau cov txheej txheem uas siv cov PCBs cais, qhov kev hloov kho thiab cov khoom hloov pauv tuaj yeem siv tau yooj yim dua.
Txhawm rau kom nkag siab ntau dua ntawm thaj chaw dav dav ntawm LCD module sib dhos, nws yog qhov tsim nyog los txiav txim siab txog cov thev naus laus zis,Tshwj xeeb tshaj yog Chip-on-Glass (COG). Lo lus nug "Dab tsi yog qhov txawv ntawm COB thiab COG?" nquag tshwm sim nyob rau hauv kev sib tham txog kev ua zaub mov module fabrication. Thaum ob qho tib si COB thiab COG koom nrog kev sib txuas ncaj qha ntawm tus tsav ICs rau lub iav substrate, cov txheej txheem ua haujlwm txawv heev. Hauv COG thev naus laus zis, tus tsav tsheb IC tau txuas ncaj qha rau iav siv anisotropic conductive zaj duab xis (ACF). Qhov ACF no muaj cov khoom siv hluav taws xob uas tsim kom muaj kev sib txuas hluav taws xob ntawm cov ntaub qhwv ntawm cov nti thiab cov ntaub qhwv sib txuas ntawm cov iav, thaum muab hluav taws xob rwb thaiv tsev nyob rau hauv lub dav hlau kab rov tav. Tsis zoo li COB, COG tsis siv cov hlua khi.
Qhov cuam tshuam ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov cuab yeej sib txuas yog qhov tseem ceeb. COG modules feem ntau nthuav tawm ib qho profile me me thiab sib zog dua piv rau lawv cov COB counterparts, raws li kev tshem tawm cov ntawv cog lus tso cai rau kev tsim kho kom zoo dua. Tsis tas li ntawd, COG feem ntau muab cov kev sib txuas zoo dua, ua kom muaj kev daws teeb meem ntau dua thiab ntau dua pixel ntom. Qhov no ua rau COG yog qhov kev xaiv zoo tshaj plaws rau kev ua haujlwm siab hauv cov xov tooj smartphones, ntsiav tshuaj, thiab lwm yam khoom siv hluav taws xob portable uas compactness thiab pom kev pom yog qhov tseem ceeb.
Txawm li cas los xij, COG thev naus laus zis kuj tseem muaj nws cov txheej txheem kev lag luam tawm. Cov txheej txheem ACF kev sib koom ua ke tuaj yeem nkag siab ntau dua rau qhov kub thiab av noo sib txawv piv rau cov khoom siv hauv COB. Tsis tas li ntawd, cov neeg kho tshuab muaj zog ntawm COG modules yuav qis dua me ntsis ntawm COB modules hauv qee qhov chaw muaj kev poob siab. Tus nqi ntawm COG los ua ke kuj tuaj yeem siab dua COB, tshwj xeeb tshaj yog rau cov zaub loj thiab cov lej ntau dua.
Tshaj li COB thiab COG, lwm yam cuab yeej uas tsim nyog hais txog yog Chip-on-Flex (COF). Hauv COF, tus tsav tsheb IC yog sib koom ua ke rau ib qho kev hloov pauv hloov pauv (FPC) uas txuas nrog lub iav substrate. COF muaj qhov sib npaug ntawm qhov compactness ntawm COG thiab cov qauv yooj yim ntawm cov tsoos PCB-mounted daws teeb meem. Nws yog feem ntau ua hauj lwm nyob rau hauv daim ntawv thov yuav tsum tau saj zawg zog zaub designs los yog qhov chaw qhov chaw txwv yuav tsum tau ib tug nyias thiab bendable interconnect.
Ntawm Malio Technology, peb txoj kev cog lus los muab cov kev daws teeb meem sib txawv thiab ua tau zoo yog pom tseeb hauv peb cov khoom lag luam dav dav. Piv txwv li, peb "COB / COG / COF Module, FE-based Amorphous C-Cores"ua piv txwv peb cov kev txawj ntse hauv kev tsim cov qauv siv ntau yam chip-on thev naus laus zis kom ua tau raws li cov ntawv thov tshwj xeeb. Ib yam li ntawd, "COB / COG / COF Module, FE-based 1K101 Amorphous Ribbon"Ntxiv underscores peb versatility nyob rau hauv kev siv cov advanced los ua ke cov tswv yim. Ntxiv mus, peb muaj peev xwm txuas mus rau customized LCD thiab LCM ntu qhia, raws li tau hais los ntawm peb lub luag hauj lwm raws li ib tug "Cage Terminal rau Metering Customized LCD / LCM Segment Zaub rau Metering."Cov piv txwv no qhia txog peb qhov kev txawj ntse hauv kev tsim kho cov kev daws teeb meem rau cov kev xav tau tshwj xeeb ntawm ntau hom kev lag luam.
Hauv kev xaus, Chip-on-Board (COB) LCD thev naus laus zis sawv cev rau txoj hauv kev tseem ceeb los tso saib module fabrication, muab qhov zoo ntawm kev compactness, robustness, thiab muaj peev xwm txhim kho hluav taws xob kev ua tau zoo. Thaum nws nthuav tawm qee qhov kev txwv txog kev rov ua kom rov zoo dua thiab tsim kev yooj yim piv rau lwm cov txheej txheem xws li COG thiab COF, nws qhov kev ua tau zoo ua rau nws muaj kev xaiv zoo rau ntau cov ntawv thov, tshwj xeeb yog cov uas xav tau kev ua haujlwm ntev thiab qhov chaw ua haujlwm. Nkag siab txog cov nuances ntawm COB thev naus laus zis, nrog rau nws qhov sib txawv los ntawm cov txheej txheem muaj feem xyuam, yog qhov tseem ceeb rau cov kws tshaj lij thiab cov neeg tsim qauv nrhiav xaiv cov kev daws teeb meem zoo rau lawv cov kev xav tau tshwj xeeb. Ntawm Malio Technology, peb nyob twj ywm nyob rau hauv pem hauv ntej ntawm kev tsim kho tshiab, muab peb cov neeg koom tes nrog cov kev paub thiab cov khoom tsim nyog los teeb pom kev zoo rau yav tom ntej.
