Kev saib ntawm HTPS LCD panel tshuab

Nrog cov koob npe ntawm DVD laser disc tshuab thiab cov digital broadcasting system, ntau cov duab siab cov duab muaj ntau zuj zus. Lub lag luam ntawm cov projector hauv ntej, lub vijtsam loj saib HDTV LCD projection TV thiab lwm lub tsev lag luam hauv tsev lag luam tau nthuav cov lag luam ntawm cov digital projector. Txoj kev loj hlob no kuj txhawb cov neeg xav tau kev pab rau peb daim LCD projector. Tsab xov xwm no yuav soj ntsuam HTPS LCD vaj huam sib luag hauv peb daim LCD projector, thiab qhia nws cov yam ntxwv.
Qhov kev thov rau HTPS vaj huam sib luag ntawm cov lag luam tawm tau txuas ntxiv nrog rau qhov kev lag luam nce ntxiv rau kev lag luam kev nthuav dav thiab cov kev siv tshuab raj tshiab uas tau nce hauv kev kawm ntawv. Tib lub sijhawm, qhov chaw ntawm DVD qhov projectors thiab digital broadcasting kuj tau tsa kev loj hlob sai ntawm cov neeg tuaj thov kev pabcuam Pem Hauv Ntej projectors thiab lub vijtsam loj LCD LCD TV projection TV (Loj TV ntsuas TV).
HTPS LCD tshuab tau ua rau peb nti LCD projection system los ua cov lag luam hauv lub lag luam mus ntev, thaum nyob hauv cov khw muag khoom siv lub teeb ntsev ntawm lub teeb ntsev (kua-crystal teeb valve), HTPS LCD tshuab raws le LCD projection system muaj ze li ntawm 55% thoob ntiaj teb kev lag luam. Qhov no yog vim muaj ntau tshaj li cov kua siv lead ua kua thiab siab qhib cov tshuab kom muaj hluav taws xob tsawg HTPS cov khoom uas muaj teeb pom kev zoo, kev ua kom pom ci ntsa iab, thiab nplua nuj xim, thiab tsis ua kev puas tsuaj rau lub qhov muag los yog ib puag ncig.


HTPS yog dab tsi?
HTPS yog lub npe ntawm Kev Kub Siab Poly-Silicon, txhais ua lus Suav yog "siab kub polysilicon" lub ntsiab lus, feem ntau hu ua kub iav. Nws yog ib qho ntawm LCD cov tsev neeg thiab muaj nyob rau hauv lub qhov taw tes kub matrix LCD (Active Matrix LCD). Yog li ntawd, HTPS kuj yog ib qho ntawm TFT (Thin Film Transistor; thin film transistors).
HTPS LCD yog ib qho ntawm cov khoom yees ntawm polycrystalline silicon TFT LCD. Yog vim li cas nws yog hu ua kub kub yog vim hais tias nyob rau hauv kev tsim cov txheej txheem ntawm lub vaj huam sib luag, muaj Laser Anneal (laser annealing) txheej txheem, uas yog ntau tshaj 1000 degrees Celsius. Nyob rau thaum ntxov ntawm txoj kev loj hlob ntawm cov txheej txheem polysilicon, thiaj li hloov cov amorphous silicon qauv ntawm iav substrate rau hauv polysilicon qauv, high oxidation tshuab ntawm ntau tshaj 1000 degrees Celsius yog tsim nyog los hloov lub amorphous silicon qauv rau hauv polysilicon qauv. Vim tias iav tsis tuaj yeem kho tau qhov kub siab, tsuas yog lub iav ntawm cov iav tuaj yeem kho tau ntau npaum li cas, nws cov nqi kim dua thiab me me loj, yog li thaum ntxov ntawm txoj haujlwm polysilicon, qhov chaw tsim tshuaj paus coj cov ciaj ciam hlaus raws li raug txiav txim siab.
Tsis tas li ntawd, muaj lwm LTPS LCD uas muaj TFT LCD (Kub Tshaj Tawm Poly-Silicon; Kub tsis muaj Polysilicon). LTPS LCD yog hu ua low temperature vim tias nws txoj kev ntsuas kub tsis siab li, nws tsuas yog li 500 ~ 600 degrees Celsius, thiab nws txawv me ntsis raws li cov txheej txheem tsim ntawm txhua lub khw. Cov txheej txheem kub hnyav ua rau siv lub laser excimer raws li qhov chaw tshav kub. Tom qab lub teeb ntawm lub laser kis tau los ntawm qhov projecting, lub teeb meem ntawm lub laser yuav tsim ib qho kev faib tawm ntawm lub zog, uas yog cia rau hauv iav substrate ntawm amorphous silicon tructure.

Thaum twg cov pob yeeb iav los ntawm cov amorphous iav substrate absorbs lub zog ntawm lub laser excimer, nws yuav tig mus rau hauv ib lub qauv polysilicon. Tag nrho cov txheej txheem ua tiav hauv qab 600 degrees Celsius, li ntawd cov iav dav hlau substrate yuav raug siv. Qhov tseem ceeb ntawm cov qauv siv tshuab polysilicon uas tsis tshua muaj siab yog hloov cov kua siv lead ua kua los txhim khu kev ua haujlwm ntawm cov tshuaj uas siv cov tshuaj ua kua silicon kua dej ua kua thiab txo cov nqi tsim. Vim tias cov tshuab LTPS tuaj yeem txhim kho qhov hluav taws xob ntawm 200 (cm2 / V-sec), nws yog qhov txiaj ntsim rau lub miniaturization ntawm TFT cheeb tsam thiab ua kom qhib qhov qhib ntawm lub vaj huam sib luag kom qhov ci ntsa iab ntawm cov duab nce thiab lub zog noj yog txo. Dhau li ntawd, cov txheej txheem uas tsis tshua muaj kev kub ntxhov yog kev siv cov iav substrates, thiab tuaj yeem txo cov nqi tsim nqi. Lub ntsiab ntawm HTPS thiab LTPS sib txawv.


HTPS LCD daim teb daim ntawv thov
HTPS qhov chaw thov feem ntau yog siv ua khoom loj. Piv txwv li, kua siv lead ua kua projector, rov qab saib TV, thiab lwm yam. Feem ntau hais lus, tus npo LCD ntawm lub xov tooj ntawm tes los yog lub computer yog qhov ncaj qha, qhov ntawd yog, tus neeg siv tau ncaj qha mus saib qhov screen thiab nyeem cov ntaub ntawv. Txawm hais tias HTPS tseem yog hom TFT, nws yuav siv tsis tau ncaj qha rau cov xov tooj ntawm tes lossis lub computer.
Daim ntawv thov HTPS LCD tau muab sib cais ua ke rau hauv peb yam nram qab no: OHD (Hla Lub Hau Zaub), Helmet thiab LV (Lub Teeb Valve). Cov kev siv loj yog raws li nram no:
OHD: lub taub hau kom pom, kev xav ntawm lub iav los (los yog iav pob), siv nyob rau hauv ib lub tsheb los yog dav hlau, nyob rau hauv ntau cov cua daj cua dub tau pom hauv lub ntsej muag;
Kws ua kaus mom hlau: Qhov no yog hais txog qhov kev siv lub tshuab muaj koob muaj npe ntawm Virtual Kev Siv Hlau.
LV: tuaj yeem muab txhais ua ib lub teeb nyob hauv lub plhaub. Thaum HTPS tsiv hauv cov kua siv lead ua kua, raws li tag nrho lub teeb kis tau los ntawm HTPS thiab txiav txim siab qhov teeb meem ntawm lub teeb los ntawm HTPS, nws yog hu ua "lub teeb valve".
HTPS LCD vaj huam sib luag nta
HTPS LCD muaj qhov zoo ntawm lub me ntim, kev siab siab thiab kev nkag siab siab, yog li nws yog qhov tsim tshwj xeeb rau peb daim yas penetrative LCD projector. Thiab kev siv ntawm HTPS LCD peb tho pob luj LCD projector, nrog peb nta, muab tus neeg pom lub ci, mos thiab xim tseeb ntuj pom kev.
Ntuj xim (Cov dluab qub)
Qhov peb daim LCD projection system tuaj yeem tswj peb xim ntawm R, G thiab B thiab tsim cov pixel ntawm daim duab, yog li ntawd daim duab yuav ua tau ntau dua qub thiab tiag tiag.
Nyiam lub zeem muag (Hlis ntawm qhov muag)
Cov duab txav ceev ceev thiab cov duab yuav tsis tshwm sim xim txawv, xws li cov duab zaj sawv.
Txaus siab tshaj (Bright Images)
Vim tias HTPS LCD yuav siv sij hawm puv hnub ntawm peb lub teeb xim, nws qhov kev kho qhov muag zoo siab heev, thiab cov neeg siv tau pom cov duab qaim thiab pom tseeb.
Tam sim no, HTPS LCD manufacturers, tag nrho ntawm Epson thiab Sony ob manufacturers, thiab ntau tshaj li ntawm Epson, qhov pib ntawm 1987 ntau lawm, rau lub Xya Hli Ntuj 2004 tau ua tag nrho 20 lab, tam sim no Epson muaj peb HTPS factories, yog lub ntiaj teb coob HTPS LCD chaw tsim tshuaj paus.
epilogue
Nrog rau cov koob laser disc tshuab thiab digital broadcasting systems, ntau cov duab siab zog tuaj zuj zus tuaj, thiab lub tshuab ua ntej, lub vijtsam loj HDTV LCD TV, thiab lwm yam khoom siv hauv tsev lub lag luam kuj tau nthuav dav sai. Lub lag luam rau digital projectors tseem nthuav, qhov kev thov rau kev lag luam muaj kev nthuav lus nce ntxiv, thiab kev thov rau kev siv computerisation ntawm cov chav kawm ua rau kev loj hlob ntawm kev lag luam. Txoj kev loj hlob no kuj txhawb cov neeg xav tau kev pab rau tsev neeg pem hauv ntej thiab cov vijtsam loj HDTV LCD projectors featuring peb nti LCD tsim yees uas cia cov neeg siv cov ntaub ntawv xov xwm hauv cov npo loj loj.
Cov neeg lag luam ntawm HTPS LCD yuav ua hauj lwm los ua cov qauv qhib, ci zog, thiab cov khoom siv me me kom tsim kom muaj zog, me dua, ntau lub hauv paus sab nrauv thiab ib qho screen loj loj HDTV LCD TV, thiab muaj nqi competitiveness tib lub sijhawm. Tam sim no muaj ntau HTPS TFT LCD panels tsim rau tsev ua yeeb yam hauv tsev, xws li 1.8cm 720p wide screen hom khoom, thiab 1.4cm 480p dav tshuaj ntsuam khoom. Los ntawm kev ruaj siab tag nrho cov kev tshawb fawb thiab kev txhim kho ntawm cov khoom siv kho tshiab cov khoom, qhov kev lag luam tom qab yuav tsum muaj kev sib tw, thiab kev lom zem ntau qhov kev zoo nkauj yuav ua rau cov neeg tau txais kev pabcuam cov neeg ua haujlwm coob tshaj plaws.
