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 cuab yeej no tau pib muab tso rau hauv lub sijhawm sim.LTPS tau los ntawm lub cim tshiab ntawm cov organic teeb-emitting vaj huam sib luag OLED kuj raug muab tso rau hauv kev siv 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 cov duab meej 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 teem kom zoo thiab ncaj qha hauv cov nplej, yog li lub electron mobility yog 200-300 zaug sai dua li ntawm amorphous 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 ua cua sov qhov chaw nyob rau hauv lub ntim txheej txheem. Tom qab cov iav substrate ntawm amorphous silicon qauv absorbs lub zog ntawm excimer laser, nws yuav hloov mus rau hauv ib tug polysilicon qauv.Vim hais tias tag nrho cov txheej txheem yog tiav ntawm 600 ℃, yog li cov dav iav substrate tuaj yeem 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 yog tsim ncaj qha rau ntawm lub vaj huam sib luag, nws tuaj yeem txo qhov kev sib cuag sab nraud ntawm cov khoom siv, ua kom muaj kev ntseeg siab, kev saib xyuas yooj yim dua, ua kom lub sijhawm sib dhos thiab txo cov yam ntxwv ntawm EMI, thiab tom qab ntawd txo cov ntawv thov tsim. lub sij hawm thiab nthuav txoj kev ywj pheej tsim.
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 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 ua rau lub module nyias thiab sib zog, thiab txo cov naj npawb ntawm cov khoom thiab lub sijhawm sib dhos; (2) Kev ua haujlwm yooj yim tuaj yeem txo lub zog noj; (3) Nruab nrog lub cim xeeb tuaj yeem txo qis kev siv hluav taws xob 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 me me thiab nruab nrab-loj zaub panels.
Txawm li cas los xij, muaj ob qhov teeb meem hauv p-Si TFT.First, lub tig-tawm tam sim no (ie to 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 hauv thaj chaw loj ntawm qhov kub thiab txias, thiab muaj qee qhov 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 cov khoom lag luam tsis ua haujlwm. Kev txhim kho hauv kev siv hluav taws xob thiab ua haujlwm ntev, nrog 170 degrees ntawm kab rov tav thiab ntsug saib cov ces kaum, 12ms ntawm lub sijhawm teb, 500 nits ntawm qhov ci, thiab 500: 1 qhov sib piv.
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 suab nrov yog sab nraud txuas nrog lub vaj huam sib luag. nrog rau cov khoom qub txeeg qub teg;
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 koom nrog 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 khoom lag luam cov ntxaij vab tshaus, kev lag luam kov cov ntxaij vab tshaus thiab cov khoom siv kho qhov muag, uas tau siv dav hauv cov khoom siv kho mob, kev lag luam. handheld terminals, Internet ntawm Tej yam terminals thiab ntse tsev.Peb muaj nplua nuj R & D thiab manufacturing kev nyob rau hauv tftLCD 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.
