I-IT House ngoJuni 17 inhlangano yocwaningo lwezindaba i-Omdia isanda kukhipha umbiko wokuthi ngo-2020 abakwaSamsung bazokhiqiza ama-polysilicon ne-oxide (LTPO) thin-film transistor (TFT) eguquguqukayo ye-OLED displays ochungechungeni lwe-Galaxy Note 20, futhi ingase ibe yi-Apple elandelayo. unyaka.Ukunikezwa kwe-iPhone.Izindaba zangaphambilini zathi i-iPhone 13 izosebenzisa isikrini se-LTPO OLED.

I-Samsung Display isungule i-LTPO TFT yayo ukuze kuthuthukiswe ukusetshenziswa kwamandla, kanyeisanda kuqamba ubuchwepheshe bayo be-LTPO njenge-mixed oxide ne-polysilicon (HOP) TFT.

AbakwaSamsung Electronics bethule i-OLED Galaxy Active 2 eguquguqukayo engu-1.2 kanye ne-1.4-inch ene-LTPO TFT ngo-2019, futhi yafakazela ukuthi impilo yebhethri yedivayisi egqokekayo ye-LTPO TFT ingcono kune-LTPS.Ngo-2020, abakwaSamsung Electronics bazosebenzisa ubuchwepheshe be-LTPO ukukhiqiza izibonisi ze-OLED eziguqukayo zochungechunge lwayo olusha lwe-Galaxy Note 20, okusho ukuthi ubuchwepheshe be-Samsung be-LTPO buzosetshenziswa kuma-smartphones angu-6.x-inch.

I-Apple iphinde yasebenzisa ubuchwepheshe be-LTPO TFT ukukhiqiza ama-OLED aguqukayo e-Apple Watch Series 4 ngo-2018, eyathuthukisa kakhulu impilo yebhethri.Muva nje, i-Apple ihlela ukusebenzisa ubuchwepheshe be-LTPO TFT ukukhiqiza ama-OLED aguquguqukayo kuma-iPhones ayo ngo-2021 ane-Samsung Display, LG Display, JDI, BOE nabanye abakhiqizi bokubonisa.I-LTPO TFT ingase ibe ubuchwepheshe obuyinhloko bokukhiqiza kwe-OLED.

I-LTPO ingonga kakhulu ukusetshenziswa kwamandla

I-LTPO TFT iyinhlanganisela ye-oxide TFT ne-polysilicon TFT.Inezinzuzo ezimbili ze-TFT technologies.I-LTPS iwubuchwepheshe obungcono kakhulu be-TFT bokusebenzisa izibonisi ze-OLED ezinokuhamba kwama-electron aphezulu, kodwa futhi inomshini wamanje wokuvuza ophakeme kakhulu ongekho esimweni.I-Oxide ubuchwepheshe obungcono kakhulu be-TFT bokusebenzisa izibonisi ze-OLED ezinokuvuza okuphansi kwamanje, kodwa ukuhamba kwayo kwe-electron kuphansi.

Ukuvuza okuphezulu kwamanje kwe-LTPS TFE kuzonciphisa ukukhanya kwesithombe ngokuhamba kwesikhathi, ngakho uhlaka ngalunye ludinga ukubhala i-voltage yokushayela.Ngakolunye uhlangothi, ukuvuza okuphansi kwamanje kwe-LTPO kudinga kuphela ukubhala i-voltage yokushayela kuhlaka lokuqala lapho isikrini singanyakazi.Ngakho-ke, i-LTPO TFT ingasetshenziswa njenge-LTPS ukubonisa okuqukethwe kweselula okudinga ukushintsha ngokushesha isimo somjikelezo we-pixel, njengamamuvi nemidlalo.Ingasetshenziswa futhi njengesekhethi ye-oxide ukubonisa okuqukethwe okumile njengezithombe noma amawashi.Isimo salolu hlobo lwesekhethi ye-pixel yesibonisi sishintsha kancane.
