Low Temperature Poly-silicon technology LTPS (Low Temperature poly-Silicon) yog thawj zaug tsim los ntawm Nyiv thiab North American cov tuam txhab thev naus laus zis txhawm rau txo qis kev siv hluav taws xob ntawm Note-PC zaub thiab ua rau Note-PC zoo li nyias thiab sib dua. Nyob rau hauv nruab nrab xyoo 1990, cov thev naus laus zis no tau pib muab tso rau hauv kev sim theem.LTPS tau los ntawm cov tiam tshiab ntawm cov organic teeb-emitting vaj huam sib luag OLED kuj raug muab tso rau hauv xyoo 1998, nws qhov zoo tshaj plaws yog ultra-nyias, lub teeb yuag, tsis muaj zog noj, tuaj yeem muab cov xim zoo nkauj dua thiab pom tseeb dua.
Tsawg kub polysilicon
TFT LCDtuaj yeem muab faib ua polycrystalline silicon (Poly-Si TFT) thiab amorphous silicon (a-Si TFT), qhov sib txawv ntawm ob qhov lus dag nyob rau hauv cov yam ntxwv sib txawv ntawm cov transistor.Cov qauv molecular ntawm polysilicon yog npaj kom huv si thiab ncaj qha hauv cov nplej, yog li cov khoom siv hluav taws xob yog 200-300 zaug sai dua li ntawm silicon.TFT-LCDhais txog amorphous silicon, mature technology, rau mainstream LCD cov khoom.Lub polysilicon feem ntau muaj xws li ob yam khoom: kub kub polysilicon (HTPS) thiab tsis kub polysilicon (LTPS).
Tsawg kub Poly-silicon; Tsawg kub poly-Silicon; LTPS (nyias zaj duab xis transistor kua siv lead ua zaub) siv excimer laser li tshav kub qhov chaw nyob rau hauv lub ntim txheej txheem. laser, nws yuav hloov mus rau hauv ib tug polysilicon qauv.Vim tag nrho cov txheej txheem yog ua tiav ntawm 600 ℃, yog li cov iav substrate dav siv tau.
Characteristic
LTPS-TFT LCD muaj qhov zoo ntawm cov kev daws teeb meem siab, cov tshuaj tiv thaiv ceev ceev, siab ci ntsa iab, siab qhib tus nqi, thiab lwm yam. Tsis tas li ntawd, vim tias cov khoom siv lead ua silicon.LTPS-TFT LCD npoyog nyob rau hauv kev txiav txim dua li a-Si, lub electron txav tau ntau dua 100 npaug siab dua, thiab lub peripheral tsav Circuit Court tuaj yeem tsim rau ntawm iav substrate tib lub sijhawm. Ua tiav lub hom phiaj ntawm kev sib koom ua ke, txuag chaw thiab tsav IC nqi.
Nyob rau tib lub sijhawm, vim hais tias tus tsav tsheb IC Circuit Court tau tsim ncaj qha rau ntawm lub vaj huam sib luag, nws tuaj yeem txo qhov kev sib cuag sab nraud ntawm cov khoom, ua kom muaj kev ntseeg siab, kev saib xyuas yooj yim dua, txo cov sijhawm sib dhos thiab txo cov yam ntxwv ntawm EMI, thiab tom qab ntawd txo qhov kev siv lub sijhawm tsim thiab nthuav dav tsim kev ywj pheej.
LTPS-TFT LCD yog lub tshuab siab tshaj plaws kom ua tiav System ntawm Vaj Huam Sib Luag, thawj tiam ntawmLTPS-TFT LCD nposiv built-in tsav tsheb Circuit Court thiab high-performance duab transistor kom ua tiav cov kev daws teeb meem siab thiab siab brightness nyhuv, tau ua LTPS-TFT LCD thiab A-Si muaj qhov sib txawv zoo.
Lub cim thib ob ntawm LTPS-TFT LCD los ntawm kev nce qib ntawm kev siv tshuab hluav taws xob, los ntawm kev sib txuas lus analog rau hauv digital interface, txo kev siv hluav taws xob.LTPS-TFT LCD npoyog 100 npaug ntawm a-Si TFT, thiab kab dav ntawm cov qauv electrode yog li 4μm, uas tsis yog tag nrho siv rau LTPS-TFT LCD.
LTPS-TFT LCDS tau zoo dua ua ke rau hauv peripheral LSI dua li tiam 2.Lub hom phiaj ntawm LTPS-TFT LCDS yog
1) tsis muaj cov khoom siv peripheral los ua kom lub module nyias thiab sib zog, thiab txo cov naj npawb ntawm cov khoom thiab lub sij hawm sib dhos; (2) Kev ua haujlwm yooj yim tuaj yeem txo qis kev siv hluav taws xob; (3) Nruab nrog lub cim xeeb tuaj yeem txo lub zog noj kom tsawg.
LTPS-TFT LCD cia siab tias yuav dhau los ua hom tshiab ntawm cov zaub vim nws qhov zoo ntawm kev daws teeb meem siab, siab xim saturation thiab tus nqi qis. Nrog rau qhov zoo ntawm kev sib koom ua ke siab thiab tus nqi qis, nws muaj qhov zoo tshaj plaws hauv daim ntawv thov ntawm cov khoom me me thiab nruab nrab cov khoom siv.
Txawm li cas los xij, muaj ob qhov teeb meem hauv p-Si TFT.First, qhov tig-tawm tam sim no (xws li xau tam sim no) ntawm TFT yog loj (Ioff = nuVdW / L); Thib ob, nws yog ib qho nyuaj rau kev npaj cov khoom muaj zog p-Si nyob rau hauv qhov chaw loj ntawm qhov kub thiab txias, thiab muaj qee yam nyuaj hauv cov txheej txheem.
Nws yog ib tiam tshiab ntawm technology muab los ntawmTFT LCD. LTPS cov ntxaij vab tshaus yog tsim los ntawm kev ntxiv cov txheej txheem laser rau cov pa amorphous silicon (A-Si) TFT-LCD panels, txo tus naj npawb ntawm cov khoom los ntawm 40 feem pua thiab cov khoom sib txuas los ntawm 95 feem pua, txo qhov feem ntawm cov khoom tsis ua hauj lwm.Qhov screen muaj kev txhim kho tseem ceeb hauv kev siv hluav taws xob thiab kav ntev, nrog 170 degrees ntawm vertical 20 lub sij hawm saib, 10 horizontal lub sij hawm. nits ntawm brightness, thiab 500: 1 contrast ratio.
Muaj peb txoj hauv kev tseem ceeb los ua ke nrog cov tsav tsheb qis p-Si:
Thawj yog hybrid kev koom ua ke hom kev luam theej duab thiab cov ntaub ntawv hloov, uas yog, kab hluav taws xob sib txuas ua ke, kev hloov pauv thiab hloov pauv kev sau npe tau koom ua ke hauv kab hluav taws xob, thiab ntau tus neeg tsav tsheb thiab lub tshuab hluav taws xob yog sab nraud txuas nrog lub vaj huam sib luag vaj huam sib luag nrog cov khoom qub;
Qhov thib ob, tag nrho cov tsav tsheb Circuit Court yog tag nrho ntawm cov zaub;
Thib peb, kev tsav tsheb thiab kev tswj xyuas Circuit Court yog kev koom ua ke ntawm lub vijtsam zaub.
Shenzhen DyogDisplay Technology Co., Ltd.yog ib lub tuam txhab high-tech integrating kev tshawb fawb thiab kev tsim kho, tsim, tsim, muag thiab kev pabcuam.Nws tsom rau kev tshawb fawb thiab kev tsim kho thiab tsim cov ntxaij vab tshaus kev lag luam, kev lag luam kov cov ntxaij vab tshaus thiab cov khoom siv kho qhov muag, uas tau siv dav hauv cov cuab yeej siv kho mob, kev lag luam handheld terminals, Internet ntawm yam terminals thiab ntse tsev.LCD npo, kev lag luam zaub screen, kev lag luam kov npo, thiab tag nrho haum, thiab koom nrog cov thawj coj hauv kev lag luam.
