Dab tsi yog cov txheej txheem tsim khoom ntawm LCD npo:
1, array manufacturing txheej txheem
1) Ib daim iav nrog lub ntsej muag du thiab tsis muaj impurities yog cov khoom siv tseem ceeb tshaj plaws rau kev ua TFT iav substrates. Ua ntej kev tsim khoom, nws yog ib qho tsim nyog yuav tsum tau ntxuav lub khob nrog cov tshuaj ntxuav tshwj xeeb, tom qab ntawd lub cev qhuav dej thiab tig kom qhuav.
2) Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm txheej txheej txheej yuav raug tsim. Hlau zaj duab xis thiab.
3) Tom qab cov yeeb yaj kiab hlau yog plated, peb kuj yuav tsum tau phaj cov txheej txheem uas tsis yog-conductive thiab semi-conductive txheej. Nyob rau hauv lub tshuab nqus tsev chamber, lub iav phaj yog rhuab ua ntej, thiab ces ib tug tshwj xeeb roj yog sprayed los ntawm high-voltage sprayer kom cov electrons thiab cov roj Plasma yog generated, thiab tom qab ib tug tshuaj tiv thaiv, ib tug uas tsis yog-conductive txheej thiab ib tug semiconductor. txheej yog tsim rau ntawm iav.
LCD
4) Tom qab cov zaj duab xis tsim, peb yuav tsum tau ua ib tug qauv ntawm transistors ntawm lub iav. Ua ntej, nkag mus rau hauv lub teeb daj daj thiab tshuaj tsuag lub photoresist nrog lub zog photosensitive, tom qab ntawd muab tso rau hauv lub photomask kom irradiate xiav-violet lub teeb rau raug, thiab thaum kawg xa tus tsim tawm mus rau qhov chaw tsim tshuaj tsuag tus tsim tawm, uas tuaj yeem tshem tawm cov photoresist. tom qab lub teeb thiab cia lub teeb Lub resist txheej yog zoo li tus.
5) Tom qab lub photoresist zoo li tus, peb tuaj yeem ua ntub dej etching kom nthuav tawm cov yeeb yaj kiab tsis muaj txiaj ntsig, lossis qhuav etching nrog cov tshuaj tiv thaiv ntawm plasma. Tom qab etching, qhov seem photoresist raug tshem tawm nrog kua, thiab thaum kawg Tsim cov qauv Circuit Court uas xav tau rau lub transistor.
6) Txhawm rau tsim ib qho siv tau nyias-zaj duab xis transistor, nws yuav tsum rov ua cov txheej txheem ntawm kev ntxuav, txheej, photoresist, raug, kev loj hlob, etching, thiab tshem tawm photoresist. Feem ntau hais lus, los tsim TFT-LCD, nws yuav tsum tau rov ua dua 5 mus rau 7 zaug.
2, txheej txheem sib dhos
1) Tom qab ua tiav cov yeeb yaj kiab nyias nyias cov iav substrate, peb yuav mus rau kev sib xyaw ua ke ntawm cov kua siv lead ua kua. Lub vaj huam sib luag ua kua yog tsim los ntawm transistor iav substrate thiab cov xim lim. Ua ntej, peb yuav tsum ntxuav lub khob ua ntej ua haujlwm. Ib kauj ruam. Tag nrho cov txheej txheem tsim khoom ntawm TFT-LCD yuav tsum nyob hauv chav huv, thiaj li yuav tsis muaj impurities hauv cov zaub.
2) Cov xim lim dej yog cov txheej txheem tshuaj pleev xim rau xim liab, ntsuab, thiab xiav ntawm lub khob, thiab tom qab ntawd nws ua tiav los ntawm kev npog nws nrog cov yeeb yaj kiab.
3) Nyob rau hauv tag nrho cov txheej txheem los ua ke, ua ntej peb yuav tsum tau coated ib txheej ntawm cov tshuaj zaj duab xis ntawm lub iav thiab xim lim npog nrog transistors, thiab tom qab ntawd ua raws li qhov kev txiav txim.
4) Ua ntej muab ob daim iav iav, peb yuav tsum xub muab qhov sib npaug ntawm qhov sib npaug zoo li qhov khoob ntawm lub sijhawm ruaj khov los tiv thaiv ob daim iav los ntawm kev nkhaus sab hauv tom qab cov kua siv lead ua kua ua ke. Feem ntau, thaum lub vaj huam sib luag ua kua siv lead ua tau sib sau ua ke, ib lossis ob qhov khoob tau tso tseg kom yooj yim rau cov khoom siv tom ntej ntawm cov kua siv lead ua kua, thiab tom qab ntawd lub ntug ntawm ob daim iav yog muab khi nrog cov sealant thiab conductive kua nplaum, yog li ua tiav cov iav sib dhos.
5) Tom qab kaw lub thav duab, muab lub LCD vaj huam sib luag nyob rau hauv lub tshuab nqus tsev chamber, thiab ntws cov huab cua los ntawm lub LCD vaj huam sib luag los ntawm qhov sib txawv cia li tseg, thiab ces ncuav lub kua siv lead ua kua nrog kev pab los ntawm atmospheric siab, thiab ces kaw qhov sib txawv. Cov kua siv lead ua kua yog ib hom Cov khoom sib xyaw ntawm cov khoom thiab cov kua muaj cov yam ntxwv ntawm kev sib xyaw molecular.
6) Thaum kawg, muab ob lub polarizers ntsug, thiab tag nrho LCD vaj huam sib luag tiav.
3, module manufacturing txheej txheem
1) Tom qab lub polarizer txuas, peb pib mount DRIVE IC ntawm ob sab ntawm lub LCD vaj huam sib luag. DRIVE IC yog ib qho tseem ceeb ntawm kev tsav tsheb, uas yog siv los tswj cov xim thiab qhov ci ntawm LCD.
2) Tom qab ntawd txuas cov tswv yim kawg ntawm DRIVE IC mus rau lub rooj tsav xwm hauv Circuit Court los ntawm kev sib txuas. Nyob rau hauv txoj kev no, lub teeb liab tuaj yeem raug xa tawm kom zoo, thiab tom qab ntawd cov duab ntawm lub vaj huam sib luag tau npaj txhij.
3) Lub teeb ntawm lub vaj huam sib luag LCD yog tawm ntawm lub teeb rov qab. Ua ntej sib dhos lub teeb nraub qaum, peb yuav xub xyuas seb lub vaj huam sib luag LCD puas zoo tag nrho, thiab tom qab ntawd sib sau lub teeb rov qab. Lub backlight yog lub hauv paus ntawm lub teeb tom qab lub LCD vaj huam sib luag.
4) Thaum kawg, xauv lub CELL thiab cov ncej hlau nrog screws.
5) Thaum peb rov qab los, peb yuav nkag mus rau cov txheej txheem xeem tseem ceeb kawg. Cov modules sib sau ua ke tau raug kuaj kev laus, thiab cov khoom tsis zoo raug tshuaj xyuas hauv lub xeev ntawm hluav taws xob thiab kub kub.
6) Cov khoom zoo tshaj plaws tuaj yeem ntim thiab xa tawm.
Nyob rau hauv txoj kev no, lub LCD vaj huam sib luag tau dhau los ua ntau yam kev soj ntsuam thiab kuaj cov txheej txheem kom xa cov khoom zoo tshaj plaws rau cov neeg siv khoom, thiab qhov no yog qhov ua tiav tiag tiag ntawm tag nrho cov txheej txheem ntawm LCD.
