Nhanganyaya kuLTPS?

Yakadzika Tembiricha Poly-silicon (LTPS) pakutanga yaive kambani yehunyanzvi muNorth America muJapan kudzikisa kushandiswa kwesimba kweCherechedzo-PC kuratidza, Iyo tekinoroji yakagadzirirwa kugadzira Note-PC kuoneka yakatetepa uye yakareruka, Pakati pemakore ekuma1990, hunyanzvi uhu yakatanga kupinda mudanho rekuyedza · Chizvarwa chitsva che organic mwenje-inoburitsa pani OLED yakatorwa kubva kuLTPS zvakare yakapinda zviri pamutemo nhanho muna 1998, Kubatsira kwayo kukuru ndeye Ultra-yakatetepa, kurema kureruka, kushandiswa kwesimba kushoma. Inogona kupa yakajeka mivara uye yakajeka images。

Yakadzika tembiricha polysilicon

 TFT LCD inogona kukamurwa kuita polysilicon (Poly-Si TFT) uye amorphous silicon (a-Si TFT), Musiyano uripo pakati pemanyepo maviri mune hunhu hweiyo transistor .Morekuru chimiro che polysilicon chakarongedzwa zvakanaka uye nenzira yegorosi, Naizvozvo, muyero wekufamba kwema electron uri 200-300 zvakapetwa kupfuura uya weakaomeswa amorphous silicon; Iyo inowanzonzi TFT-LCD inoreva amorphous silicon, Mature tekinoroji, Ndicho chigadzirwa chikuru cheLCD .Polysilicon zvigadzirwa zvinonyanya kusanganisira yakakwira-tembiricha polysilicon (HTPS) uye yakadzika-tembiricha polysilicon (LTPS).

 Yakadzika Tembiricha Poly-nesilicon (LTPS) yakatetepa firimu transistor emvura kristaro anoratidzira ari muchirongwa chekupakata, Uchishandisa excimer laser senge inopisa sosi, Mushure mekunge laser mwenje ichipfuura neprojekti, Inoburitsa danda re laser rine yunifomu yekuparadzira simba, Yakatemerwa girazi substrate ine amorphous silicon mamiriro, Kana iyo amorphous silicon dhizaini girazi substrate inotora simba reiyo excimer laser, Ichashandura kuita polysilicon chimiro, Nekuti iyo yose yekurapa maitiro inopera pazasi pe600 ℃, Naizvozvo, girazi substrates anoshanda.

Hunhu

  LTPS-TFT LCD ine zvakanakira resolution yakakwira, kupindura nekukasira, kupenya kwakakwirira, uye kukwirisa kukwirisa .Ukuwedzera, sezvo iyo silicon kristaro kurongeka kweLTPS-TFT LCD yakanyanya kurongeka kupfuura iyo ya-Si, Ita iyo elektroni kufamba mwero yakakwira kupfuura ka100, Iyo yedenderedzwa yekutyaira wedunhu inogona kugadzirwa pane yegirazi substrate panguva imwe chete, Svika chinangwa chehurongwa hwekubatanidzwa, chengetedza nzvimbo uye kutyaira IC mutengo.

  Panguva imwecheteyo, Sezvo mutyairi IC wedunhu akagadzirwa zvakananga panhepfenyuro, Inogona kudzora nzvimbo dzekunze dzezvinhu, Wedzera kuvimbika, kugadzirisa zviri nyore, kupfupisa nguva yegungano uye kudzora hunhu hweEMI, Izvi zvinoderedza nguva yekugadzira yeiyo system yekushandisa uye inowedzera iyo dhizaina rusununguko.

  Iyo yepamusoro tekinoroji yeLTPS-TFT LCD ndeyekuwana System paPaneru, Chizvarwa chekutanga cheLTPS-TFT LCD inoshandisa yakavakirwa-mukati dhiraivha wedunhu uye epamusoro-mashandiro epikisheni mapikisheni kuti uwane kugadziriswa kwakanyanya uye kupenya kwakakwira. Yakagadzira LTPS-TFT LCD uye a-Si vane musiyano mukuru.

  Chizvarwa chechipiri cheLTPS-TFT LCD kuburikidza nekufambira mberi kwetekinoroji yedunhu, Kubva pane inoenderana neanalog interface kune dhijitari interface, Deredza kushandiswa kwesimba. Mufambiro wekutakura wechizvarwa chino cheLTPS-TFT LCD inguva zana iyo yeA-Si TFT, Iyo electrode pateni dhayamita upamhi ndeye 4μm, Hunhu hweLTPS-TFT LCD hausati hwashandiswa zvizere.

  Chizvarwa chechitatu LTPS-TFT LCD yakanyanyisa kuzara padanho rakakura rakabatanidzwa redunhu (LSI) kusangana kupfuura yechipiri-chizvarwa, Chinangwa chayo ndechekuti: (1) Iko hakuna zvikamu zvepariperi kuita kuti module ireruke uye ipfupike, Inogona zvakare kudzikamisa huwandu hwenzvimbo uye musangano man-maawa; (2) Yakareruka gadziriso yekugadzirisa inogona kudzikisira kushandiswa kwesimba; (3) Yakashongedzerwa nendangariro kudzikisa kushandiswa kwesimba.

  Nekuti LTPS-TFT LCD yemvura kristaro inoratidzira ine zvakanakira resolution yepamusoro, yakakwira color saturation, uye yakachipa mutengo, Hombe tarisiro dzinoiswa pane itsva wave maficha.Neayo akakwirira wedunhu ekubatanidza hunhu uye yakaderera mutengo zvakanakira, Iyo ine yakakwana mhedzisiro mukushandiswa kwemadhiyamu madiki uye epakati-epakati ekuratidzira Asi p-Si TFT ine matambudziko maviri, Rimwe nderekuti off-state yazvino (kureva leakage yazvino) yeTFT yakati kurei (Ioff = nuVdW / L); Chechipiri, zvinonetsa kugadzirira kwepamusoro-kufamba p-Si zvigadzirwa munzvimbo hombe pane tembiricha dzakaderera Pane mamwe matambudziko mukuita uku.

  Icho chitsva chizvarwa tekinoroji chigadzirwa chakatorwa kubva kuTFT LCD. Iyo LTPS skrini inogadzirwa nekuwedzera iyo laser yekugadzirisa maitiro kune echinyakare amorphous silicon (a-Si) TFT-LCD mapaneru. Huwandu hwezvinhu hunogona kudzikiswa ne40%, Uye iyo chinongedzo chikamu chinogona kudzikiswa ne95%, Zvakanyanya kudzikisira mukana wechigadzirwa kutadza.Ichi skrini chakavandudzika zvakanyanya maererano nekushandisa kwesimba uye kugadzikana, Dzose dzakatwasuka uye dzakamira yekuona angles dzinogona kusvika 170 degrees, Ratidza kupindura nguva kusvika ku12ms, Iyo kuratidza kupenya kunosvika mazana mashanu nits, Chiyero chinopesana chinogona kusvika 500: 1.

Pane nzira nhatu huru dzekubatanidza yakaderera-tembiricha p-Si madhiraivha:

1, Mbeu dzakauchikwa kusangana kwekutarisa uye kushandura dhata, Iyo dunhu inosanganisirwa pamwe, Iyo switch uye yekuchinja rejista inosanganisirwa mukoramu wedunhu, Multiple yekutaura madhiraivha nema amplifera zvakabatana kune yakatetepa pani kuratidza nemaakagara nhaka;

2, All nemotokari masekiti zvakazara revatema pamusoro vanoratidza chidzitiro;

3, Drive uye kudzora matunhu vari revatema pamusoro vanoratidza chidzitiro.
