Nyias zaj duab xis transistor kua siv lead ua kua

  • Active matrix kua Crystal Display (AMLCD) yog ib qho khoom siv nrog ob lossis peb hnub ntawm txhua cov kua siv lead ua pixel, yog li ntawd cov kev tswj ntawm txhua tus pixel yog tus neeg ywj siab, thiaj li ua tau zoo duab zoo tsuas yog kev cuam tshuam ntawm pixels.

  • Raws li qhov sib txawv li ub li no, lawv muaj peev xwm raug muab faib ua peb qho kev sib tshooj dav hlau thiab ob lub tshooj dav hlau uas tsis tau sib txuas ntawm ob qho tag nrho.

  • Peb qhov davhlau ya nyob twg nquag tsav tsheb ntawm transistor suav nrog kev siv cov crystal silicon MOS thiab nyias zaj duab xis nyhuv transistor TFT.

  • Nyias zaj duab xis transistor LCD TFT-LCD yog feem ntau TN ua hauj lwm hom.

  • Iav substrates yog txawv ntawm cov quas LCD. Ntawm sab qis substrate, peb yuav tsum luam cov kab txuas thiab sab nrauv tuaj rau daim ntawv teev nyiaj, thiab ua rau TFT yam khoom siv thiab pixel electrodes ntawm lawv cov kev sib tshuam.

Lub micro LCD vaj huam sib luag yuav pom liab ntsuab xiav raws li txheej txheej ntawm kev sib tw, feem ntau yog ib pab pawg los yog ob pawg ua ke pixel.


Tus tsiaj ntawm AMLCD

l   TFT yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hauv lub tshuab ua matrix ua kua (AMLCD). Raws li cov ntaub ntawv siv hauv nws cov txheej txheem semiconductor, AMLCD yuav muab faib ua ib pob crystal silicon Si MOSFET, polycrystalline silicon p-Si, amorphous silicon a-Si thiab tsis muaj silicon khoom TFT-AMLCD.

      l   Monocrystalline silicon: muaj peev xwm ua kom siv qhov kev sib txuas ntawm lub voj voog tshuab kom ncaj nraim cov duab ntawm monocrystalline silicon chip, yooj yim kom paub meej txog kev daws teeb meem thiab cov qauv me me substrate. Txawm li cas los xij, cov kabmob loj dawb monocrystalline silicon wafers yog qhov nyuaj los npaj thiab ua cov ntawv loj loj.

       l   Cov silicon: CdSe thiab Te, qhov ruaj ntseg thiab uniformity ntawm cov ntaub ntawv yog cov neeg pluag.



TFT hom kua siv lead ua kua

l   Tus ua hauj lwm txoj cai ntawm TFT yog zoo li MOSFET, thiab qhov TFT array txheej txheem zoo li cov txheej txheem ntawm kev npaj MOSFET ntawm lub pob zeb ntim, tab sis cov ntawv yuav hloov mus rau hauv lub iav substrate, thiab cov qauv ntaus ntawv siv daim ntawv ntawm zaj duab xis.

l   Ib txheej ntawm silicon yog tso rau hauv iav substrate, thiab ib tug transistor array yog tsim los ntawm kev luam lithography. Txhua lub pixel muaj lub semiconductor hloov, uas zoo ib yam li ib qhov loj hauv kev sib tsuam. Tom qab ntawd lub TN kua siv lead ua kua dej ua rau ntawm ob daim iav.

l   Vim tias txhua pixel tuaj yeem tswj tau los ntawm tus taw tes mem tes, txhua qhov ntawm kuj ywj siab thiab tswj tau tsis tu ncua. Qhov kev tsim no tsis yog pab txhim kho cov lus teb kom ceev ceev xwb, tab sis kuj yog tswj cov theem ntawm cov xim grey, yog li cov xim ntawm TFT kua siv lead ua kua dej ntau dua.

l   Cais cov xim peb xim rau peb qhov tshwj xeeb, txhua qhov uas hloov cov grey sib txawv, thiab tom qab ntawd suav txog cov ntsiab lus teev hauv peb peb RGB li pixels.

l   TFT AM LCD yog ua los ntawm TN hom kua siv lead ua kua ntawm ob tsom iav.

l   Qhov qis substrate yog nruab nrog lub cuab yeej TFT ua ib lub pixel hloov, pixel hluav taws xob rau cov zaub, lub tshuab hluav taws xob (kab) tswj cov kab sib chaws ntawm TFT, thiab ib lub vev-xaij (kem) tswj cov TFT qhov kawg .

l   Lub qaum substrate yog siv los npaj cov xim lim zaj duab xis thiab cov zauv dub uas siv rau kev ntxoov ntxoo, thiab cov ntaub qhwv pej xeem tawm sab nraud yog npaj rau hauv substrate.

l   Cov txheej txheem nplaum yog ua hauv ob lub iav substrates kom paub cov kua siv lead ua kua tshuaj.

l   Cov kua siv lead ua kua yog sib tov ntawm ob daim iav, thiab tau sib txuas los ntawm cov txheej txheem sealing, thiab tib lub sijhawm, nws plays lub luag haujlwm. Khwv kis tau qee lub nrig rau ntawm lub substrate los ua kom tsis muaj qhov sib txawv ntawm qhov sib txawv.

l   Txhawm rau xa cov hluav taws xob hauv nruab nrab ntawm sab sauv substrate mus rau sab qis substrate thiaj li txuas nrog qhov kev sib tshuam hauv plhaus nkoos, qhov sib txuas qhov chaw (sib cuag) yog npaj ntawm ob daim iav nrog nyiaj lo hniav nyiaj.

l   Sab ob sab ntawm ob lub iav substrates yog txuas nrog rau lub ncov qaum ntuj

l   Tsis tas li ntawd, kab sib tsoo thiab teeb liab ntawm qhov teeb meem ntawm amorphous silicon TFT yuav tsum tau txuas nrog rau lwm tus neeg sab nraud thiab lub PCB Circuit Board. Qhov qis substrate yog me ntsis loj tshaj lub qis substrate, thiab ntug yog npaj nrog lub siab vuam taw tes.
