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. Mukati memakore ekuma1990, tekinoroji iyi yakatanga kuiswa muchikamu chekuyedza.LTPS yakabva kuchizvarwa chitsva che organic light-emitting panel OLED yakashandiswawo zviri pamutemo muna 1998, mabhenefiti ayo makuru ndeekupedzisira-mutete, uremu hwakareruka, kushandiswa kwesimba kushoma, kunogona kupa mamwe mavara anoyevedza uye mifananidzo yakajeka.
Low tembiricha polysilicon
TFT LCDinogona kupatsanurwa kuita polycrystalline silicon (Poly-Si TFT) uye amorphous silicon (a-Si TFT), musiyano pakati pezviviri zviri mune akasiyana transistor maitiro.The molecular structure yepolysilicon yakarongedzwa zvakanaka uye yakananga muGrain, saka kufamba kwerekitironi kunokurumidza 200-300 nguva kupfuura iyo yeamorphous silicon.TFT-LCDinoreva amorphous silicon, tekinoroji yakakura, yezvigadzirwa zveLCD zvakanyanya. Iyo polysilicon inonyanya kusanganisira marudzi maviri ezvigadzirwa: tembiricha yepamusoro polysilicon (HTPS) uye yakaderera tembiricha polysilicon (LTPS).
Yakadzika Temperature Poly-silicon; Yakadzika tembiricha poly-Silicon; LTPS (yakaonda firimu transistor liquid crystal display) inoshandisa excimer laser senzvimbo yekupisa mukurongedza.Mushure meiyo laser mwenje ichipfuura nepakati chirongwa cheprojekiti, iyo laser beam ine yunifomu yekugovera simba ichagadzirwa uye inoratidzwa pagirazi substrate yeamorphous silicon chimiro. shandurwa kuita polysilicon chimiro.Nekuti iyo yese process inopedzwa pa600℃,saka general glass substrate inogona kuiswa.
Characteristic
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, nyore kugadzirisa, kupfupisa nguva yegungano uye kuderedza EMI maitiro, uyezve kuderedza iyo application system yekugadzira nguva uye kuwedzera dhizaini rusununguko.
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 kwekunakira kwayo kwepamusoro resolution, yakakwira color saturation uye yakaderera mutengo.Nezvakanakira zvekukwira kwedunhu kubatanidzwa uye kudhura kwakaderera, ine mukana wakakwana mukushandiswa kwediki uye nepakati-saizi yekuratidzira mapaneru.
Zvakadaro, pane matambudziko maviri mu p-Si TFT. Chekutanga, kudzima ikozvino (kureva kuvuza ikozvino) kweTFT kwakakura (Ioff=nuVdW/L); Chechipiri, zvakaoma kugadzirira kufamba kwepamusoro p-Si zvinhu munzvimbo huru pane tembiricha yakaderera, 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. kupenya, uye 500:1 musiyano wechiyero.
Pane nzira nhatu huru dzekubatanidza yakaderera-tembiricha p-Si vatyairi:
Yekutanga ndiyo hybrid yekubatanidza maitiro e scan uye data switch, kureva kuti, mutsara wedunhu wakabatanidzwa pamwe chete, chinja uye chinja regisheni inosanganiswa mumutsara wedunhu, uye akawanda ekutaura mutyairi uye amplifier akabatana nekunze kune flat panel inoratidzwa neyakagarwa nhaka;
Chechipiri, yese dhiraivha yekutyaira yakanyatsobatanidzwa pachiratidziro;
Chechitatu, dhiraivha uye kudzora maseketi akabatanidzwa pane yekuratidzira skrini.
