Ubushyuhe buke polysilicon tekinoroji LTPS itangiza

Ubushyuhe buke bwa tekinoroji ya Poly-silicon LTPS (Ubushyuhe buke bwa poly-Silicon) bwakozwe bwa mbere n’amasosiyete y’ikoranabuhanga y’Ubuyapani n’amajyaruguru ya Amerika hagamijwe kugabanya ingufu zikoreshwa mu kwerekana Note-PC no gutuma Note-PC igaragara neza kandi yoroshye. Mu myaka ya za 90 rwagati, iryo koranabuhanga ryatangiye gushyirwa mu cyiciro cy’ibigeragezo.LTPS ikomoka ku gisekuru gishya cy’ibikoresho bitanga urumuri kama OLED nayo yakoreshejwe ku mugaragaro mu 1998, ibyiza byayo ni ultra-thin, uburemere bworoshye, gukoresha ingufu nke, irashobora gutanga amabara meza cyane n'amashusho asobanutse.

Ubushyuhe buke polysilicon

TFT LCDirashobora kugabanywa muri silicon polycrystalline (Poly-Si TFT) na silicon amorphous (a-Si TFT), itandukaniro riri hagati yibi byombi mubiranga transistor itandukanye. Imiterere ya molekuline ya polysilicon itunganijwe neza kandi itaziguye mu ngano, bityo moteri ya electron ikubye inshuro 200-300 kurenza iya silicon amorphous.TFT-LCDbivuga amorphous silicon, tekinoroji ikuze, kubicuruzwa bikuru bya LCD. Polysilicon ikubiyemo ubwoko bubiri bwibicuruzwa: ubushyuhe bwinshi bwa polysilicon (HTPS) hamwe nubushyuhe buke bwa polysilicon (LTPS).

Ubushyuhe buke bwa Poly-silikoni; Ubushyuhe buke bwa poly-Silicon; LTPS (thin film transistor fluid fluid crystall display) ikoresha lazeri ya excimer nkisoko yubushyuhe mugikorwa cyo gupakira.Nyuma yumucyo wa lazeri unyuze muri sisitemu ya projection, urumuri rwa lazeri hamwe nogukwirakwiza ingufu zingana bizakorwa kandi byerekanwe kumirahuri yikirahure yububiko bwa amorphous silicon bizaba byahinduye amikoro ya silicon amimusi ya amorphous silicon. imiterere.Kuberako inzira yose yarangiye kuri 600 ℃, bityo substrate rusange yikirahure irashobora gukoreshwa.

Characteristic

LTPS-TFT LCD ifite ibyiza byo gukemura cyane, umuvuduko wihuse, umuvuduko mwinshi, umuvuduko mwinshi wo gufungura, nibindi.LTPS-TFT LCDni murutonde kuruta a-Si, moteri ya elegitoronike irenga inshuro 100 hejuru, kandi umuzenguruko wa peripheri urashobora guhimbwa kuri substrate yikirahure icyarimwe. Kugera ku ntego yo guhuza sisitemu, kubika umwanya no gutwara ibiciro bya IC.

Muri icyo gihe, kubera ko umushoferi IC umuzunguruko ukorerwa ku buryo butaziguye ku kibaho, birashobora kugabanya itumanaho ryo hanze ry’ibigize, kongera ubwizerwe, kubungabunga byoroshye, kugabanya igihe cyo guterana no kugabanya ibiranga EMI, hanyuma bikagabanya igihe cyo gushushanya sisitemu yo gusaba no kwagura ubwisanzure bwo gushushanya.

LTPS-TFT LCD nubuhanga buhanitse bwo kugera kuri Sisitemu kuri Panel, igisekuru cya mbere cyaLTPS-TFT LCDukoresheje ibinyabiziga byubatswe hamwe na transistor-yerekana amashusho menshi kugirango ugere kumurongo wo hejuru kandi urumuri rwinshi, byatumye LTPS-TFT LCD na A-Si bifite itandukaniro rinini.

Igisekuru cya kabiri cya LTPS-TFT LCD binyuze mumajyambere yikoranabuhanga ryumuzunguruko, kuva muburyo bugereranywa no muburyo bwa digitale, bigabanya ingufu zikoreshwa.LTPS-TFT LCDni inshuro 100 zijyanye na a-Si TFT, kandi ubugari bwumurongo wuburyo bwa electrode bugera kuri 4μm, budakoreshwa neza kuri LTPS-TFT LCD.

LTPS-TFT LCDS yinjijwe neza muri LSI ya peripheri kuruta Igisekuru 2.Intego ya LTPS-TFT LCDS ni1) kutagira ibice bya periferi kugirango module yorohe kandi yoroshye, kandi igabanye umubare wibice nigihe cyo guterana; (2) Gutunganya ibimenyetso byoroheje bishobora kugabanya gukoresha ingufu;

LTPS-TFT LCD iteganijwe guhinduka ubwoko bushya bwo kwerekana kubera ibyiza byayo byo gukemura cyane, kwiyuzuza amabara menshi hamwe nigiciro gito. Hamwe ninyungu zo guhuza imiyoboro myinshi hamwe nigiciro gito, ifite inyungu zuzuye mugushira mubikorwa bito n'ibiciriritse byerekana.

Ariko, hariho ibibazo bibiri muri p-Si TFT.Bwa mbere, kuzimya umuriro (ni ukuvuga umuyoboro wa leakage) wa TFT nini (Ioff = nuVdW / L); Icya kabiri, biragoye gutegura ibikoresho byimuka p-Si ahantu hanini mubushyuhe buke, kandi hariho ingorane runaka mubikorwa.

Nibisekuru bishya byikoranabuhanga bikomokaTFT LCD. Ibice bya LTPS bikozwe mugushyiramo lazeri muburyo busanzwe bwa amorphous silicon (A-Si) TFT-LCD, kugabanya umubare wibigize 40% no guhuza ibice 95%, bikagabanya cyane amahirwe yo gutsindwa nibicuruzwa. Mugaragaza itanga iterambere ryinshi mugukoresha amashanyarazi no kuramba, hamwe na dogere 170 zumwanya utambitse kandi uhagaritse, 12m zumucyo, hamwe na 500: 1.

Hariho uburyo butatu bwingenzi bwo guhuza ubushyuhe buke p-Si abashoferi:

Iya mbere ni uburyo bwo guhuza uburyo bwo gusikana no guhinduranya amakuru, ni ukuvuga ko umurongo uzunguruka wahujwe hamwe, kwandikirana no guhinduranya byinjijwe mu murongo w’umurongo, kandi abashoferi benshi ba adresse hamwe na amplifier bahujwe hanze na tekinike igaragara hamwe n'umuzunguruko uzungurwa;

Icya kabiri, ibinyabiziga byose bigenda byuzuzanya byuzuye;

Icya gatatu, gutwara no kugenzura imiyoboro ihuriweho kuri ecran yerekana.
