Yakaderera Temperature Poly-silicon tekinoroji LTPS(Yakaderera Temperature poly-Silicon) yakatanga kugadzirwa neJapan neNorth America tekinoroji makambani kuitira kudzikisa kushandiswa kwesimba kweCherechedzo-PC kuratidza uye kuita kuti Cherechedzo-PC iite seyakatetepa uye yakareruka.Pakati pemakore ekuma1990, tekinoroji iyi yakatanga kuiswa muchiyedzo.LTPS yakabva kuchizvarwa chitsva cheorganic light-emitting panel OLED yakashandiswawo zviri pamutemo muna 1998, mabhenefiti ayo makuru ndeekupedzisira-mutete, kureruka, simba rakaderera. kushandiswa, kunogona kupa mamwe mavara akanaka uye mifananidzo yakajeka.
Low tembiricha polysilicon
TFT LCDinogona kupatsanurwa kuita polycrystalline silicon (Poly-Si TFT) uye amorphous silicon (a-Si TFT), mutsauko uripo pakati pezviviri izvi uri mune akasiyana transistor maitiro.Mamolecular chimiro chepolysilicon yakarongedzwa zvakanaka uye yakananga muMbeu, saka iyo Mobility yeelectron inokurumidza 200-300 times pane iya yeamorphous silicon.Inowanzozivikanwa seTFT-LCDinoreva amorphous silicon, tekinoroji yakakura, yezvigadzirwa zveLCD zvakanyanya. Iyo polysilicon inonyanya kusanganisira marudzi maviri ezvigadzirwa: tembiricha yepamusoro polysilicon (HTPS) uye yakaderera tembiricha polysilicon (LTPS).
Yakaderera Temperature Poly-silicon; Yakadzika tembiricha poly-Silicon; LTPS (yakaonda firimu transistor liquid crystal display) inoshandisa excimer laser semhepo inopisa mukurongedza. kugadzirwa uye kuratidzwa pagirazi substrate yeamorphous silicon chimiro.Mushure meiyo girazi substrate yeamorphous silicon chimiro inotora simba re excimer laser, ichashandurwa kuita polysilicon chimiro.Nekuti iyo yese inopedzwa pa600℃,saka iyo general girazi substrate inogona kuiswa.

LTPS-TFT LCD ine zvakanakira kugadziriswa kwepamusoro, kukurumidza kuita kukurumidza, kupenya kwepamusoro, kuvhurika kwakanyanya, nezvimwe. Pamusoro pezvo, nekuti silicon crystal kurongwa kweLTPS-TFT LCDiri kurongeka kupfuura a-Si, kufamba kwerekitironi kwakakwira kanopfuura ka100, uye dhiraivha yekutyaira inogona kugadzirwa pagirazi substrate panguva imwe chete.Zadzisa chinangwa chekubatanidza system, chengetedza nzvimbo uye kutyaira IC mutengo.
Panguva imwecheteyo, nekuti mutyairi IC wedunhu anogadzirwa zvakananga pane pani, inogona kuderedza kubatwa kwekunze kwechikamu, kuwedzera kuvimbika, kugadzirisa kuri nyore, kupfupisa nguva yegungano uye kuderedza EMI maitiro, uyezve kuderedza dhizaini yehurongwa hwekushandisa. nguva uye kuwedzera rusununguko rwekugadzira.
LTPS-TFT LCD ndiyo yepamusoro-soro tekinoroji yekuwana System pane Panel, chizvarwa chekutanga cheLTPS-TFT LCDkushandisa yakavakirwa-mukati mutyairi wedunhu uye yakakwirira-inoshanda mufananidzo transistor kuwana yakakwirira resolution uye yakakwirira kupenya maitiro, yaita kuti LTPS-TFT LCD uye A-Si ive nemusiyano mukuru.
Chizvarwa chechipiri cheLTPS-TFT LCD kuburikidza nekufambira mberi kwetekinoroji yedunhu, kubva kuanalog interface kuenda kudhijitari, kuderedza kushandiswa kwesimba.Kufamba-famba kwechizvarwa chino.LTPS-TFT LCDiri ka100 pane yea-Si TFT, uye upamhi hwemutsara wepateni ye electrode ingangoita 4μm, isingashandiswe zvizere kuLTPS-TFT LCD.
LTPS-TFT maLCDs ari nani akabatanidzwa muperipheral LSI pane Generation 2. Chinangwa cheLTPS-TFT LCDS ndechekuita.
1) isina mativi eparutivi kuita kuti module iite mutete uye kureruke, uye kuderedza huwandu hwezvikamu uye nguva yegungano; (2) Yakareruka masaini magadzirirwo anogona kuderedza kushandiswa kwemagetsi; (3) Yakashongedzerwa nendangariro inogona kuderedza kushandiswa kwesimba kusvika kushoma.
LTPS-TFT LCD inotarisirwa kuve rudzi rutsva rwekuratidzira nekuda kwemabhenefiti ayo epamusoro resolution, yakakwira color saturation uye yakaderera mutengo.Nezvakanakira zvekukwirira dunhu kubatanidzwa uye mutengo wakaderera, ine mukana wakakwana mukushandiswa kwediki uye. mapenera epakati nepakati.
Nekudaro, pane matambudziko maviri mu p-Si TFT. Chekutanga, iyo yekudzima-yezvino (kureva kuvuza ikozvino) yeTFT yakakura (Ioff = nuVdW / L); Chechipiri, zvakaoma kugadzirira kufamba kwakakwira p-Si zvinhu mukati nzvimbo huru pane yakaderera tembiricha, uye pane kumwe kuoma mukuita.
Icho chizvarwa chitsva cheteknolojia yakabvaTFT LCD.LTPS skrini inogadzirwa nekuwedzera laser process kune yakajairwa amorphous silicon (A-Si) TFT-LCD mapaneru, ichidzikisa huwandu hwezvikamu ne40 muzana uye kubatanidza zvikamu ne95 muzana, zvichideredza zvakanyanya mukana wekutadza kwechigadzirwa. kuvandudzwa mukushandiswa kwesimba uye kusimba, iine 170 madhigirii eyakachinjika uye yakatwasuka ekuona angles, 12ms yenguva yekupindura, 500 nits yekupenya, uye 500: 1 musiyano wechiyero.
Pane nzira nhatu huru dzekubatanidza yakaderera-tembiricha p-Si vatyairi:
