IT House nge-17 kaJuni umbutho wophando weendaba u-Omdia usandula kukhupha ingxelo yokuba ngo-2020 i-Samsung iya kuvelisa i-polysilicon kunye ne-oxide (LTPO) ethambileyo yefilimu ye-transistor (TFT) eguquguqukayo ye-OLED kuluhlu lwe-Galaxy Note 20, kwaye inokuba yi-Apple elandelayo. unyaka.Unikezelo lwe-iPhone.Iindaba zangaphambili zathi i-iPhone 13 iya kusebenzisa isikrini seLTPO OLED.

I-Samsung Display iphuhlise i-LTPO TFT yayo ukwenzela ukuphucula ukusetyenziswa kwamandla, kunyekutshanje ithiye itekhnoloji ye-LTPO njenge-oxide edibeneyo kunye ne-polysilicon (HOP) TFT.

I-Samsung Electronics yaphehlelela i-1.2 kunye ne-1.4-intshi eguquguqukayo ye-OLED ye-Galaxy Watch Active 2 ene-LTPO TFT ngo-2019, kwaye yangqina ukuba i-LTPO TFT isixhobo esinxitywayo ubomi bebhetri bungcono kune-LTPS.Ngo-2020, i-Samsung Electronics iya kusebenzisa iteknoloji ye-LTPO ukuvelisa iziboniso ze-OLED eziguquguqukayo kuchungechunge lwayo olutsha lwe-Galaxy Note 20, okuthetha ukuba iteknoloji ye-LTPO ye-Samsung iya kusetyenziswa kwii-smartphones ze-6.x-intshi.

I-Apple iphinde yasebenzisa iteknoloji ye-LTPO TFT ukuvelisa ii-OLED eziguquguqukayo ze-Apple Watch Series 4 ngo-2018, ephucule kakhulu ubomi bebhetri.Kutshanje, i-Apple iceba ukusebenzisa iteknoloji ye-LTPO TFT ukuvelisa ii-OLED eziguquguqukayo kwii-iPhones zayo ngo-2021 kunye ne-Samsung Display, i-LG Display, i-JDI, i-BOE kunye nabanye abavelisi bokubonisa.I-LTPO TFT inokuba yitekhnoloji ephambili yokwenziwa kwe-OLED.

I-LTPO inokugcina kakhulu ukusetyenziswa kwamandla

I-LTPO TFT yindibaniselwano ye-oxide TFT kunye ne-polysilicon TFT.Ineenzuzo zetekhnoloji ezimbini ze-TFT.I-LTPS yeyona teknoloji ibalaseleyo ye-TFT yokusebenzisa iziboniso ze-OLED ezinokushukuma kwe-electron ephezulu, kodwa ikwanowona mgangatho uphezulu wokuvuza wangoku.I-Oxide yeyona teknoloji ye-TFT igqwesileyo yokusebenzisa iziboniso ze-OLED ezinokuvuza okuphantsi kwe-state, kodwa ukuhamba kwayo kwe-electron kuphantsi.

Ukuvuza okuphezulu kwangoku kwe-LTPS TFE kuya kunciphisa ukuqaqamba komfanekiso kunye nexesha, ngoko ke isakhelo ngasinye kufuneka sibhale umbane wokuqhuba.Kwelinye icala, ukuvuza okuphantsi kwangoku kwe-LTPO kufuna kuphela ukubhala amandla ombane okuqhuba kwisakhelo sokuqala xa isikrini singashukumi.Ke ngoko, i-LTPO TFT ingasetyenziswa njenge-LTPS ukubonisa umxholo weselula odinga ukutshintsha ngokukhawuleza imeko yesekethe ye-pixel, efana neemovie kunye nemidlalo.Isenokusetyenziswa njengesekethe ye-oxide ukubonisa umxholo omileyo njengemifanekiso okanye iiwotshi.Ubume bolu hlobo lomboniso wesekethe ye-pixel itshintsha kancinane.
