Luv qhia txog TFT-LCD

Mar 22, 2017

Luv qhia txog TFT-LCD txheej txheem kev siv tshuab thiab cov txheej txheem ua lag luam (tiag tiag AUO fab)

Txoj kev xaus

TFT (Thin Film Transistor) LCD thin zaj duab xis field effect transistor (LCD) yog ib hom roj ntsha siv ua kua (AM-LCD). Cov kua siv ua kua teeb pom kev zoo, tshwj xeeb tshaj yog TFT-LCD, tam sim no tsuas yog thiab tso ntau dua CRT tag nrog cov kev kawm ntawm ci ntsa iab, qhov sib piv, lub zog, lub neej, qhov loj me thiab qhov hnyav, nws qhov kev ua tau zoo, Cov khoom, cov ntaub ntawv nyoos, cov khoom nyhav, cov nqi qis, qhov chaw dav dav rau kev loj hlob, yuav yog cov ntsiab lus ntawm lub xyoo tshiab, nws yog ib qho tseem ceeb ntawm lub xyoo pua nees-nkaum thoob ntiajteb.

Ntsiab Ntaus

TFT qhia txog kev siv ntawm "rov qab los" - qhov uas txoj kev xav hauv lub teeb duab tsis zoo li TN LCD txij saum toj mus rau hauv qab, tab sis txij qab qis. Qhov kev qhia no yog teeb nyob rau sab nraum qab ntawm cov kua siv lead ua cov yeeb nkab tshwj xeeb, lub teeb pom kev thaum thaum raug lub teeb los ntawm lub ncov qaum. Qhov electrode hauv kev sib tw hauv FET electrode thiab cov electrode, cov FET electrode tau ua, qhov kev ua tau ntawm cov kua siv lead ua kua hloov yuav hloov, ua teeb thiab shading kom ua tiav lub hom phiaj ntawm qhov qhia tau tias, lub sijhawm teb tau nce mus txog 80ms . Vim nws siab dua TN-LCD zoo ib yam thiab ntau dua cov yeeb yuj, kev tshuaj ntsuam ceev dua, lub TFT hu ua "true color".

Piv nrog DSTN, lub ntsiab feature ntawm TFT-LCD yog siv lub teeb nruab nrab ntawm cov twj siv hluav taws xob rau txhua lub pixel. Vim txhua pixel tau ncaj qha tswj tau los ntawm cov txiaj ntsig pa. Yog li txhua txoj ntawm kuj ywj siab thiab tswj tau tsis tu ncua. Txoj kev tsim qauv no tsis yog ua rau kev txhim kho kom ceev cov lus teb, tab sis tseem muaj peev xwm tswj tau cov yeeb yam ntawm grey, uas yog vim li cas qhov TFT xim muaj tseeb tshaj DSTN.

Qhov zoo tshaj plaws

Nrog rau kev loj hlob ntawm TFT technology nyob rau hauv 90s thaum ntxov, kev loj hlob ntawm xim LCD tiaj tus vaj huam sib luag zaub, tsawg tshaj li 10 xyoo, kev loj hlob sai ntawm TFT-LCD mus rau hauv lub ntsiab zaub, uas muaj nws qhov zoo yog inseparable. Cov nta tseem ceeb yog:

(1) kev siv cov kev pab zoo

Tsab ntawv teev npe ntawm qhov tsis tshua muaj hluav taws xob, tsis tshua tsav tsheb, muaj kev ruaj ntseg thiab muaj kev ruaj ntseg zoo tuaj; Ca, thiab nyias, txuag ntau ntau cov ntaub ntawv raw thiab siv qhov chaw; Tsis muaj hwj chim ntau, kev siv zog yog hais txog CRT zaub 1/10, sab laug thiab ib feem pua qhia TFT-LCD txawm tsuas yog CRT, txuag ntau zog thiab cov khoom siv TFT-LCD; Specification, me me series, ntau yam, yooj ywm thiab yooj yim mus use, txij nkawm, hloov tshiab, yooj yim rau kev hloov, lub neej ntev kev ua haujlwm thiab ntau lwm yam nta. Teeb pom kev sib txawv ntawm 1 ntiv mus txog 40 nti tawm tag nrho cov ntawv thov dav thiab dav dav dav dav dav dav dav dav dav dav dav dav dav; zaub zoo los ntawm cov feem ntau si mple monochromatic cim graphics rau siab daws teeb meem, siab xim fidelity, siab brightness, siab zoo, siab teb kev ceev ntawm lub video zaub los ntawm ntau yam specifications; Zaub muaj ib hom ncaj nraim ntawm hom kev xav, qhov kev xam pom, thiab hom kev xav.

(2) qhov chaw tiv thaiv zoo

Tsis muaj hluav taws xob, tsis muaj teeb meem, tsis ua mob rau cov neeg mob. Hauv particular, cov tsos ntawm TFT-LCD hauv phau ntawv thiab thev naus laus zis, yuav coj tib neeg mus rau hauv qhov chaw ua haujlwm tsis muaj ntawv, tsis muaj daim ntawv luam tawm, ua rau tib neeg kawm, nthuav tawm thiab cov ntaub ntawv ntawm kev sib haum xeeb ntawm kev ncaj ncees.

(3) dav dav ntawm daim ntawv thov

Nws tuaj yeem siv rau feem ntau hauv qhov kub ntawm thaj tsam ntawm -20 DEG C txog +50 DEG C, thiab ua haujlwm kub ntawm TFT-LCD yuav raug txo kom txog 80 degrees hauv qab xoom. Tus qauv siv hluav taws xob tsis yog siv tau los ua ib qho khoom dav hlau mobile, tab sis kuj siv tau ua ib qho loj screen projection tv.

(4) kev kawm siab ntawm automation hauv kev siv tshuab

Loj nplai muaj cov cwj pwm txawv txav. TFT-LCD kev lag luam mature technology, loj teev qhov khoom tiav lawm 90% lossis ntau dua.

(5) TFT-LCD yog yooj yim mus integrate thiab hloov tshiab

Nws yog qhov sib xyaw kom zoo ntawm cov nplai loj ntawm cov khoom siv hluav taws xob thiab cov teeb pom kev zoo siv tshuab. Tam sim no, muaj amorphous, polycrystalline thiab monocrystalline silicon TFT-LCD, yuav muaj lwm yam khoom yav tom ntej TFT, ob qho tib si iav substrate thiab yas substrate.

Cov txheej txheem TFT (thin film transistor process)

1, Cov txheej txheem Array (array process)

Nyob rau hauv cov ntaub ntawv ntawm AUO, TFT-LCD vaj huam sib luag tsim txoj kev tiag tiag Hoobkas

Tsuas yog muab tso rau, TFT-LCD panels yuav tsum tau ua rau ob daim iav substrate sandwiched ntawm cov kua siv lead ua kua, lub iav iav substrate nrog xim lim (xim Lim), thaum lub iav qis yog inlaid hauv lub transistor sab sauv. Thaum hloov tam sim no hauv hluav taws xob los ntawm lub transistor, kua siv lead ua kua molecules ua rau deflection ntawm lub teeb nyob rau hauv thiaj li yuav hloov lub bias polarity, ces siv Polaroid kev txiav txim siab pixels (Pixel) thiab tsaus xeev. Tsis tas li ntawd, vim hais tias lub iav thiab xim lim lamination daim ntawv txhua pixel (Pixel) txhua yam muaj peb xim xiav ntsuab ntsuab, uas tawm xim ntsuab xiav thiab ntsuab xim muab cov duab pixel ntawm lub vijtsam vaj huam sib luag.

Lub ntsiab ntawm 3 lub ntsiab ntawm TFT-LCD:

Anterior ntu Array

Cov txheej txheem ua ntej thiab cov txheej txheem kev tsim hluav taws xob zoo ib yam yog zoo li, tab sis qhov txawv yog qhov nyias zaj duab xis transistors fabricated rau iav, tsis txhob silicon wafer.

Nruab Nrab Lub Cev

Qhov nruab nrab ntawm Cell, yog pawg lus dhau los: Array iav ua cov substrate, thiab xim lim iav substrate, thiab nruab nrab ntawm ob iav substrate rau cov kua siv lead ua kua (LC).

Ncej Module Sib Dhos (Module Assembly)

Tom qab cov txheej txheem sib dhos haum yog txheej txheem tom qab lub khob iav thiab lwm tus xws li kev teeb pom kev zoo, lub voj voos, thiab lwm yam khoom sib txuam ua ke.

TFT-LCD: qauv nyuaj

Cov dej ua kua siv ua kua dej ua kua, cov kua siv xuab zeb ua ke ntawm ob lub iav substrates, ob lub iav substrate yog TFT Array iav thiab xim xim. TFT Array iav saum ib lub priels ntawm pixels (pixel) txheej txheem, xim xim yog lub hauv paus ntawm kev tshuaj ntsuam xim, lub LCD yuav tsum ntawm cov npoo TFT thiab Array xim. Thaum qhov voltage tau thov TFT (transistor), kua siv lead ua kua, ces lub teeb dhau kis los ntawm cov kua siv ua kua ua kua los tsim ib lub pixel, thiab lub teeb qhov chaw module yog lub luag haujlwm los muab cov teeb ci ntsa iab. Lub sij hawm no, cov xim xim ntawm txhua lub pixel muab ib qho xim. Nrog ib tug txawv xim rau txhua pixel ntawm daim duab ntawm lub vaj huam sib luag pem hauv ntej yog.

TFT-LCD: qauv nyuaj

Tom qab ntau tshaj 300 kev

Lub TFT-LCD yuav tsum tau tsim nyob rau hauv chav tu huv, nrog ntau tshaj 300 kev ua haujlwm. Huv huv chav huv, theem siab txog "10", uas yog, hauv chav tsev huv, txhua lub cubic cub xwb 10 hmoov av.

TFT-LCD Hoobkas - cim thiab me me

Lub TFT-LCD cog tau hloov zuj zus los ntawm cov dhau los ntawm 1 tiam mus rau tam sim no tiam ntawm lub cim 7.5. Qhov txawv ntawm cov tiam no yog qhov loj ntawm lub khob substrate. Qhov loj dua lub iav substrate, qhov loj qhov loj ntawm lub vaj huam sib luag yuav txiav. Piv txwv li, ib lub cim ntawm iav 7.5 xyoo loj me me mus txog 195 cm X 225 cm, qhov loj ntawm ntau tshaj ob lub txaj kom nce, nws tuaj yeem txiav mus rau hauv yim daim ntawm 42 nti vaj huam sib luag, los yog 6 pieces ntawm 46 nti vaj huam sib luag.

TFT-LCD Ntej-kawg txheej txheem - Array

Tus txheej txheem tsim ntawm TFT-LCD yuav muab faib ua peb theem: ua ntej Array, nruab nrab Cell, thiab rooj sib tham module. Cov txheej txheem Array zoo ib yam li cov txheej txheem ntawm semiconductor, tab sis qhov txawv yog hais tias nyias zaj duab xis transistors rau iav, ntau ntawm silicon wafers.

TFT-LCD Ntej-kawg txheej txheem - Array

TFT-LCD-txheej txheem - Array

Qhov nruab nrab ntawm Cell, yog yav dhau los ntawm pawg TFT Array iav raws li lub substrate, thiab xim lim iav substrate, thiab ob daim iav substrate ntawm cov kua siv lead ua rau lub substrate, thiab muab txiav rau hauv lub iav loj loj.

TFT-LCD txheej txheem ntawm tes

TFT-LCD ncej txheej txheem - module sib dhos

Tom qab qhov kev sib sau ua ke, yog lub xov tooj ntawm tes nrog iav tom qab txiav, thiab lwm yam khoom xws li lub rooj tsavxwm Circuit Court, backlight, ncej thiab lwm yam khoom sib xyaw ua ke.
