Quantum dots thiab encapsulation
Raws li cov khoom tshiab nano cov khoom siv, cov quantum dots (QDS) muaj kev ua tau zoo vim nws loj. Cov duab ntawm cov khoom no yog spherical lossis quasi-spherical, thiab txoj kab uas hla ntawm nws los ntawm 2NM txog 20nm. QDS muaj ntau qhov zoo, xws li bluorescent lub neej, tshwj xeeb tshaj yog cov ntxig rau QDS tuaj yeem npog cov teeb meem tag nrho los ntawm kev hloov nws qhov loj me.
Ntawm cov haiv neeg QDScent, the ⅱ ~ ⅵ QDS suav nrog CDSE tau thov rau cov ntawv thov uas muaj nqi nrawm dua. Lub ib nrab-ncov qhov dav ntawm ⅱ ~ ⅵ QDS Ranges los ntawm 30nm mus rau 50nm, uas tuaj yeem qis dua 30nm, cov fluorescence quantees tawm ntawm lawv yuav luag nce 100%. Txawm li cas los xij, lub xub ntiag ntawm CD txwv txoj kev txhim kho ntawm QDS. Qhov ⅲ ~ ⅴ qds uas tsis muaj CD tau tsim ntau, cov fluorescence Qeas tawm los ntawm cov khoom no yog kwv yees li 70%. Ib nrab-ncov qhov dav ntawm lub teeb ntsuab inp / Zns yog 40 ~ 50 nm, thiab lub teeb liab inp / Zns yog kwv yees li 55 nm. Cov cuab yeej ntawm cov khoom no yuav tsum tau txhim kho. Tsis ntev los no, ABX3 AOVECTSKites uas tsis tas yuav npog cov plhaub qauv tau nyiam ntau yam. Lub hwj chim nthwv dej ntawm lawv tuaj yeem hloov kho hauv qhov pom pom yooj yim. Cov fluorescence Qaib cov txiaj ntsig los ntawm cov pob txha caj dab yog ntau tshaj li 90%, thiab ib nrab-ncov-siab dav dav yog kwv yees li 15nm. Vim tias cov xim gamut ntawm QDS Luminescent cov ntaub ntawv tuaj yeem mus txog 140% NTSC, hom ntaub ntawv no muaj cov ntawv siv zoo hauv cov khoom siv luminescent. Cov ntawv thov tseem ceeb muaj nrog tsis tshua muaj lub ntiaj teb phosphor rau emit teeb uas muaj ntau cov xim thiab teeb pom kev zoo hauv cov hluav taws xob nyias.
QDS qhia cov xim teeb pom kev zoo rau cov khoom siv no tuaj yeem tau txais qhov ntev ntawm cov teeb pom kev zoo, uas ib nrab dav ntawm nthwv dej ntev yog qis dua 20nm. Cov QDDS muaj ntau cov yam ntxwv, uas muaj cov xim emitting yooj yim, nqaim emission spectrum, siab fluorescence quantCum tau tawm los. Lawv tuaj yeem siv los ua kom zoo rau lub spectrum hauv LCD Backlights thiab txhim kho cov xim sib zog thiab kev twv txiaj ntawm LCD.
Cov txheej txheem encapsulation ntawm QDS yog raws li hauv qab no:
1) on-nti: cov hmoov fluorescent hmoov yog hloov los ntawm cov khoom siv lrch luminescentulation, uas yog qhov encapsulationing citectulation ntawm QDS hauv teeb pom kev zoo. Qhov zoo ntawm qhov no ntawm nti yog ob peb tus nqi, thiab qhov tsis zoo yog cov khoom yuav tsum muaj kev ruaj khov siab.
2) saum npoo: Cov qauv yog siv hauv Backlight. Lub qhov muag zaj duab xis yog ua los ntawm cov QDS, uas yog txoj cai saum LGP hauv Blu. Txawm li cas los xij, tus nqi siab ntawm thaj chaw loj ntawm kev ua yeeb yaj kiab kho qhov muag tsawg tsawg qhov kev siv ntawm cov qauv no.
3) on-ntug: QDS cov ntaub ntawv yog encapsulated rau sawb, thiab muab tso rau ntawm sab ntawm LED Sawb thiab LGP. Txoj kev no txo cov teebmeem ntawm kev kub thiab hluav taws xob kho qhov muag uas tshwm sim los ntawm xiav LED thiab QDS LAKEST cov khoom. Ntxiv mus, kev siv ntawm cov qit cov ntaub ntawv kuj tseem poob.
