Luv qhia txog iav substrate

1. Tus qauv ntawm iav substrate

Daim iav substrate muaj ob feem ntawm CF thiab TFT, xws li:

2. Ib qho kev taw qhia luv luv rau cov txheej txheem tsim ntawm iav substrate

  Cov txheej txheem ntawm TFT-LCD tseem muab faib ua peb theem, namely, tsim theem ntawm TFT array substrate, tsim theem ntawm TFT-LCD thiab tsim theem ntawm tus qauv LCD.

3. Qhov txheej txheem ntawm iav substrate

Lub caij tsim ntawm TFT array substrate
Tus txheej txheem ntawm TFT array yog tsuas yog ntxuav, zaj duab xis sib sau, thiab ces daj lub teeb phaj, ces etched txheej txheem tsim cov qauv Desired, thiab ces raws li tus naj npawb ntawm photomellus ua ib tug txheej txheem kev voj voog. Hauv cov txheej txheem ntawm lub voj voos, ntxuav iav substrate yog thawj xa mus rau txaws lub rooj rau plated nrog cov txheej hlau, thiab ces cov xim daj thiab etch siv los tsim lub rooj vag, lub regional qauv, iav puag tom qab lub Sui Dynasty . Lub phaj raug ntxuav los ntawm photoresist thiab tom qab ntawd ces siv thaj tsam ua haujlwm nrog cov yeeb nkim cheeb tsam hauv plasma pab tshuaj lom neeg lub cev tso dej. Tom qab muaj kev sib koom tes, TFT hauv cheeb tsam tiv thaiv txheej txheem tau tsim nyob rau hauv qhov poplar ntawm cov tshuaj vapor deposition hauv cheeb tsam yeeb yaj kiab, lub kaum sab xis tau pom, thiab txheej txheem ntawm oxide zaj duab xis (ITO) tau tawg, thiab thaj tsam daim duab kos tau tsim los ntawm cov txheej txheem daj thiab etch. Nyob rau hauv qhov txheej txheem ntawm no, etching los ntawm TFT yog cov kauj ruam tseem ceeb.
Qhov sib lawv liag ntawm TFT tus qauv nyob ntawm qhov sib lawv liag ntawm qhov dej, qhov chaw thiab poob dej, uas tuaj yeem muab faib ua plaub hom. Piv txwv, tam sim no, tus tso zis TFT feem ntau raws li rov qab qauv qauv, thiab vim nws cov qauv yog qhov yooj yim thiab cov txheej txheem yog ib qho yooj yim siv los ntawm TFT tuam ntxhab, thiab cov txheej txheem muab faib ua: 1) tom qab cov channel etching TFT, 2) tom qab TFT los yog tom qab ntawd peb txheej. Cov kauj ruam tseem ceeb ntawm kev tsim cov ntaub ntawv ntawm TFT.TFT yog N cov nyom silicon nyob rau hauv cov channel kawg tom qab etching tsim ib lub qhov rooj kaw tswj, uas feem ntau qhuav etching, uas ua rau cov leakage tam sim no, uas tej zaum yuav yooj yim muab khaws cia hauv lub cim xeeb ntawm tus mos lwj qhuav.

Lub caij ua tiav ntawm TFT-LCD

    Tom qab tiav tag nrho cov txheej txheem hauv TFT-LCD iav, iav uas yog tshuab nrog xim liab, ntsuab, thiab xiav xim, ua ntej sib luag nrog cov yeeb yaj kiab, sib phim nrog txoj kev kho mob, cov xim ntawm lub kav hlau, thiab ces ob daim iav ntawm iav, qhov txiav ntug thiab lub kaum sab xis kev qhia, ntxuav, cov kua tshuaj pleev thiab lub sealing, thiab qhov kev kuaj zaum kawg thiab kev kuaj hluav taws xob. Cov kauj ruam tseem ceeb yog raws li nram no:
1) kev saib xyuas kev sib koom tes
Tam sim no, txoj kev ua txhua yam yog txoj kev txhuam thiab kev sib tsoo, uas yog siv los ntawm cov khoom siv lead ua kua qaub rau ib qho kev taw qhia tom qab lub dov ntawm lub flannelette ntawm cov hlau hlau.
2) lub taub dej ntawm lub kav hlau
Lub hom phiaj yog kom tau txais cov khoom siv ua kua uas tsis muaj xim, nws tuaj yeem tau txais CELL GAP ntau dua yog hais tias qhov ceev tshaj plaws yog qhov siab. Yog tus spacer leaked, qhov zoo yuav txo. Tshaj ntawd, qhov qis dua qhov kev poob qis ntawm tus spacer tuaj yeem tsis tau qhov CELL GAP, thiab nws yuav cuam tshuam txog qhov zoo. Nws yog qhov yooj yim uas tswj tus ceev. Ua ntej, nchuav lub nrig rau sab saum toj, thiab khi tus ncej kom tiav qhov sib xyaw ua ke ntawm CF thiab TFT.

3) vaj huam sib luag nrog kev sib xyaw ua ke ntawm TFT thiab CF thiab ces qhov kev txiav thiab refracturing nrog lub zog nyuaj steel hlau cutter thiab refracturing. Lub tom qab Sui style, qhov loj thiab cov qauv txheej nrawm ntawm cov ncej puab, txoj kev loj hlob, lub tshuab ultra tawv tsis tau raws li qhov yuav tsum tau, tom qab laser txiav hom.

4) cov kua tshuaj pleev kom siv cov iav hauv tshuab cav nrog sab nrauv. Thaum siv txoj kev ncaj nraim los hno ua kua siv lead ua kua ua kua, peb yuav tsum tau ua tib zoo saib xyuas kom tsis txhob ua rau lub pob tawg nthe thiab lub thoob pob tawm. II xub thawj ua lub CELL nrog lub tshuab nqus tsev, thiab mam li nqos cov kua hluav taws xob ntawm CELL rau cov kua siv lead ua kua , thiab tom qab ntawd ces siv cov nitrogen ua rau lub tshuab nqus tsev, thiab sab hauv thiab sab nraud txawv qhov sib txawv thiab cov ntaub thaiv npog. Cov kua siv lead ua kua yuav raug muab coj mus rau hauv sab hauv ntawm CELL thaum kua crystal yog txhaj.

Spacer tawg: yog txhaj rau cov kua siv lead ua kua, cov kua siv lead ua kua yog cov loj loj thiab ob daim khob iav thaum lawv nias ua ke.
Spacer aggregation: Thaum cov kua siv lead ua kua yog txhaj, muaj cov loj thiab cov khoom me me hauv cov kua siv lead ua kua. Vim hais tias cov kua siv lead ua me me, nws yuav dov hauv nruab nrab zawj, thiab qee tus ntawm lawv yuav tsim ib pob txhua tus.
5) qhov muag kuaj thiab hluav taws xob ntsuas
Qhov kev tshuaj ntsuam tseem ceeb ntawm LCD CELL project yog txhuam xyuas cov tshuaj tom qab ua kua dej ntshiab, pib lub tshev kos thiab kuaj zaum kawg. Tag nrho cov kev ntsuam xyuas no ua rau pom kev.
• LCD module tsim theem
Cov txheej txheem module muaj xws li kev sib txuas ntawm txav iav substrate, qhov hluav taws xob hlawv, nias, sib tsoo, kev sib tsoo thiab kev kuaj ntawm chassis thiab qaum.


4.Cov khoom noj khoom haus

Feem ntau ntawm qhov ua rau muaj kev phem tshwm sim yog los ntawm cov txheej txheem nto iav. Feem ntau, qhov khib nyiab feem ntau yog tsis tsim nyog vim kev xav ntawm lub hauv paus substrate kom raug muab tshem tawm ntawm qhov chaw. Tab sis thaum muaj qhov hnyav hnyav txhawm rau kom tsis txhob muaj cov txheej txheem nqes, nws feem ntau tsis zoo, thiab tus txheej txheem CF yog muab los ntawm CF, lub zog ntawm cov extraction thiab cov khoom cais. Cov txheej txheem feem ntau ua rau khawb, abrasions, defects nyob rau hauv txawv teb chaws lub cev thiab substrate, los yog plhaub sinking.

Sab hauv: khawb, kos, punctate qhov txhab thiab ntab deg hauv cheeb tsam zoo ntawm CF iav qauv.
Txawv teb chaws cov khoom nyob rau hauv nws: metallic txawv teb chaws lub cev nyob rau hauv CF iav, qias tuaj, npuas, tawg iav protuberances thiab lwm lub teb chaws txawv.
Iav cev qhuav: qhov sawv los yog plaub lub kaum ntawm lub hauv paus phaj ntawm lub hauv paus phaj raug puas vim txiav los yog qwj ntses.
Cov txheej txheem iav tawg: thaum lub sij hawm tsim kev lag luam ntawm CF substrate, muaj ib lub teb chaws txawv ntawm cov txheej, uas ua rau saum npoo ntawm cov substrate tshwm protrusion.
Iav tawg: hnyav iav tawg.
Tsib. Txoj kev loj hlob
1) kev daws teeb meem
2) high brightness
3) sab nrauv
4) qis zog siv
5) tus nqi tsim khoom tsawg
