Low kutentha kwa polysilicon ukadaulo wa LTPS

Ukadaulo wa Low Temperature Poly-silicon LTPS(Low Temperature poly-Silicon) udapangidwa koyambirira ndi makampani aukadaulo aku Japan ndi North America kuti achepetse kugwiritsa ntchito mphamvu kwa chiwonetsero cha Note-PC ndikupanga Note-PC kuwoneka yocheperako komanso yopepuka. M'katikati mwa zaka za m'ma 1990, lusoli linayamba kuikidwa muyeso.LTPS yochokera ku gulu latsopano la organic light-emitting panel OLED inagwiritsidwanso ntchito mu 1998, ubwino wake waukulu ndi wowonda kwambiri, wopepuka, wochepa mphamvu, amatha kupereka mitundu yokongola komanso zithunzi zomveka bwino.

Kutentha kochepa kwa polysilicon

TFT LCDakhoza kugawidwa mu polycrystalline pakachitsulo (Poly-Si TFT) ndi amorphous silikoni (a-Si TFT), kusiyana pakati pa awiriwa amagona zosiyanasiyana transistor makhalidwe.The maselo a polysilicon dongosolo mwaukhondo ndi Directively mu njere, kotero kuyenda elekitironi ndi 200-300 nthawi mofulumira kuposa silicon amorphous.TFT-LCDamatanthauza silicon amorphous, luso okhwima, kwa ambiri LCD products.The polysilicon makamaka zikuphatikizapo mitundu iwiri ya mankhwala: mkulu kutentha polysilicon (HTPS) ndi otsika kutentha polysilicon (LTPS).

Low Temperature Poly-silicon; Low kutentha poly-Silicon; LTPS (woonda filimu transistor madzi kristalo anasonyeza) amagwiritsa excimer laser monga gwero kutentha mu ma CD ndondomeko. kusandulika polysilicon structure.Chifukwa ndondomeko yonseyo imatsirizidwa pa 600 ℃, kotero gawo lapansi la galasi lingagwiritsidwe ntchito.

Cwovutitsa

LTPS-TFT LCD ili ndi ubwino wa kusamvana kwakukulu, kufulumira kuchitapo kanthu, kuwala kwakukulu, kutsegulira kwakukulu, etc. Komanso, chifukwa makonzedwe a silicon crystalChithunzi cha LTPS-TFTndi molingana kuposa a-Si, kuyenda kwa ma elekitironi ndikokwera kwambiri kuposa nthawi 100, ndipo kuzungulira kozungulira kumatha kupangidwa pagawo lagalasi nthawi yomweyo. Fikirani cholinga cha kuphatikiza dongosolo, sungani malo ndikuyendetsa mtengo wa IC.

Pa nthawi yomweyo, chifukwa dalaivala IC dera mwachindunji opangidwa pa gulu, akhoza kuchepetsa kukhudzana kunja kwa chigawo chimodzi, kuonjezera kudalirika, zosavuta kukonza, kufupikitsa nthawi msonkhano ndondomeko ndi kuchepetsa makhalidwe EMI, ndiyeno kuchepetsa dongosolo ntchito kamangidwe nthawi ndi kukulitsa kamangidwe ufulu.

LTPS-TFT LCD ndiukadaulo wapamwamba kwambiri wokwaniritsa System pa Panel, m'badwo woyamba waChithunzi cha LTPS-TFTkugwiritsa ntchito madalaivala opangidwa ndi madalaivala komanso mawonekedwe apamwamba kwambiri azithunzi kuti akwaniritse kusamvana kwakukulu komanso kuwala kwambiri, kwapangitsa kuti LTPS-TFT LCD ndi A-Si zikhale ndi kusiyana kwakukulu.

M'badwo wachiwiri wa LTPS-TFT LCD kudzera mukupita patsogolo kwaukadaulo wozungulira, kuchokera ku mawonekedwe a analogi kupita ku mawonekedwe a digito, kuchepetsa kugwiritsa ntchito mphamvu.Chithunzi cha LTPS-TFTndi nthawi 100 kuposa a-Si TFT, ndipo m'lifupi mzere wa elekitirodi chitsanzo ndi pafupifupi 4μm, amene si mokwanira ntchito LTPS-TFT LCD.

LTPS-TFT maLCD amaphatikizidwa bwino mu LSI yozungulira kuposa Generation 2.Cholinga cha LTPS-TFT LCDS ndi1) alibe zigawo zotumphukira kuti gawoli likhale locheperako komanso lopepuka, komanso kuchepetsa kuchuluka kwa magawo ndi nthawi ya msonkhano; (2) Kuwongolera ma sigino osavuta kumatha kuchepetsa kugwiritsa ntchito mphamvu; (3) Kukhala ndi kukumbukira kumatha kuchepetsa kugwiritsa ntchito mphamvu pang'ono.

LTPS-TFT LCD ikuyembekezeka kukhala mtundu watsopano wowonetsera chifukwa cha zabwino zake zowoneka bwino, kukhathamiritsa kwamtundu wapamwamba komanso mtengo wotsika.Ndi zabwino zophatikizira dera komanso mtengo wotsika, ili ndi mwayi wogwiritsa ntchito mapanelo ang'onoang'ono ndi apakatikati.

Komabe, pali mavuto awiri p-Si TFT.Choyamba, kuzimitsa panopa (ie kutayikira panopa) ya TFT ndi yaikulu (Ioff = nuVdW/L); Chachiwiri, n'zovuta kukonzekera mkulu kuyenda p-Si zinthu m'dera lalikulu kutentha otsika, ndipo pali vuto linalake ndondomeko.

Ndi mbadwo watsopano wa teknoloji yochokera kuTFT LCD. LTPS zowonetsera amapangidwa ndi kuwonjezera ndondomeko laser kwa ochiritsira amorphous silicon (A-Si) TFT-LCD mapanelo, kuchepetsa chiwerengero cha zigawo zikuluzikulu ndi 40 peresenti ndi kulumikiza mbali ndi 95 peresenti, kuchepetsa kwambiri mwayi wa mankhwala failure.Szenera amapereka kusintha kwambiri mu kagwiritsidwe ntchito mphamvu ndi durability, ndi 170 madigiri yopingasa mawonedwe ngodya ndi 50 nthawi yopingasa, 170 digiri yopingasa mawonedwe ngodya ndi 50 nthawi yopingasa,2 kuwala, ndi 500: 1 kusiyana pakati.

Pali njira zitatu zazikulu zophatikizira madalaivala otsika a p-Si:

Yoyamba ndi njira yophatikizira yosakanizidwa yojambulira ndi kusintha kwa data, ndiko kuti, mzere wozungulira umalumikizidwa palimodzi, cholembera chosinthira ndi chosinthira chimaphatikizidwa mugawo la mzere, ndipo oyendetsa maadiresi angapo ndi amplifier amalumikizidwa kunja ndi chiwonetsero chazithunzi ndi gawo lotengera;

Chachiwiri, dera lonse loyendetsa galimoto likuphatikizidwa bwino pawonetsero;

Chachitatu, mabwalo oyendetsa ndi owongolera amaphatikizidwa pazenera.

Shenzhen DiziMalingaliro a kampani Display Technology Co., Ltd.Ndi bizinesi yapamwamba kwambiri yophatikiza kafukufuku ndi chitukuko, kupanga, kupanga, kugulitsa ndi ntchito. Imayang'ana pa kafukufuku ndi chitukuko ndi kupanga zowonetsera mafakitale, zowonetsera mafakitale ndi zinthu zopangira kuwala, zomwe zimagwiritsidwa ntchito kwambiri pazida zamankhwala, malo ogwiritsira ntchito m'manja, Internet of Things terminals ndi smart home.Chithunzi cha LCD, nsalu yowonetsera mafakitale, nsalu yotchinga ya mafakitale, ndi zoyenera, ndipo ndiwe mtsogoleri wa makampani owonetsera mafakitale.
