Luam tawm rau Lub Yim Hli 9, 2024, thaum 15:30 EE zaus Nyiv
Ib pab pawg tshawb fawb los ntawm Nyiv Hokkaido University tau ua ke tsim ib qho "oxide nyias-zaj duab xis ntawm 78cm2 / vs zoo heev nrog Kochi University of Technology. Nws yuav muaj kev tsav cov ntxaij vab tshaus ntxiv 8k OLED TVS.
Qhov saum npoo ntawm cov txheej txheem txheej hlau nyias nyias zaj duab xis yog them nrog cov yeeb yaj kiab tiv thaiv, txhim kho ruaj khov
Nyob rau hauv Lub Yim Hli 2024, pab pawg tshawb fawb nrog rau cov xibfwb qhia ntawv, tshaj tawm kev sib koom tes nrog lub tsev kawm txuj ci hauv tshuab hluav taws xob "nrog kev sib koom tes hluav taws xob" nrog kev sib koom tes hauv tsev kawm ntawv Nws yuav muaj kev tsav cov ntxaij vab tshaus ntxiv 8k OLED TVS.
Current 4K OLED TVs use oxide-IGZO thin-film transistors (a-IGZO TFTs) to drive the screens. Lub tshuab hluav taws xob tsis muaj peev xwm ntawm lub tendentor no yog li 5 txog 10 cm2 / vs. Txawm li cas los xij, tsav lub vijtsam ntawm ib tiam tom ntej no 8k Oxide nyias-zaj duab xis trantor nrog rau hluav taws xob kev musility ntawm 70 cm2 / vs lossis ntau dua yog xav tau.
Pab xibfwb cov xibfwb Mago thiab nws pab neeg tsim lub TFT nrog kev mus ncig hauv nruab nrab ntawm 140 cm2 / vs 2022, siv ib zaj ua yeeb yaj kiab ntawmInium oxide (in2o3)rau txheej nquag. Txawm li cas los xij, nws tsis tau muab tso rau kev siv vim tias nws cov ruaj khov (kev cia siab) yog tsis zoo vim yog cov adsorption vim yog cov adsorption vim yog cov roj av hauv huab cua.
Lub sijhawm no, cov pab pawg tshawb nrhiav tau txiav txim siab los npog cov npoo nyias uas muaj cov yeeb yaj kiab tiv thaiv kom tiv thaiv roj los ntawm kev tshaj tawm hauv huab cua. Cov txiaj ntsig sim qhia tau tias tfts nrog cov yeeb yaj kiab tiv thaivyttrium oxidethiabErbium oxidenthuav tawm tsis muaj kev ruaj khov. Ntxiv mus, kev mus ncig hluav taws xob yog 78 cm2 / vs, thiab cov yam ntxwv tsis hloov txawm tias thaum muaj voltage ntawm ± 20v tau thov rau 1.5 teev, tshuav.
Ntawm qhov tod tes, ruaj khov tsis tau txhim kho hauv tfts uas siv hafnium oxide lossisTxhuas Oxideraws li cov yeeb yaj kiab tiv thaiv. Thaum lub atomic kev tswj tau pom siv lub tshuab hluav taws xob hauv tshuab hluav taws xob, nws tau pom tiasIndium oxide thiabyttrium oxide tau nruj nreem ntawm qib atomic (heterOepitaxial kev loj hlob). Nyob rau hauv kev sib piv, nws tau lees tias nyob rau hauv tfts uas nws txoj kev ruaj khov tsis tau txhim kho, lub interface ntawm indium oxide thiab cov yeeb yaj kiab tiv thaiv tau amorphous.
