Dab tsi Ua Perovskites cog lus rau Display Technology?

Perovskite, uas tau tawm ntawm qhov tsom teeb rau ntau xyoo, tam sim no tau tshwm sim los ua ib qho ntawm cov khoom saib zoo tshaj plaws nyob rau tom ntej - tiamzaub kev lag luamrau 2026.

Yav dhau los, perovskites feem ntau cuam tshuam nrog - tiam photovoltaics. Niaj hnub no, txawm li cas los xij, nrog kev ua tiav hauv cov thev naus laus zis xws li lub teeb ntsuab thiab xiav lub teeb emission, electroluminescence, thiab xim hloov, cov khoom no tau nkag mus rau hauv cov saw hlau ntawm LED, Micro LED, thiab quantum dot zaub. Los ntawm kev ua tau zoo nyob rau hauv chav kuaj mus rau kev sim- teev ntau lawm los ntawm cov tuam txhab thiab cov khoom xa tawm xa tawm, perovskites tau maj mam hloov los ntawm "lub tswv yim thev naus laus zis" mus rau theem ntawm kev siv tau zoo.

Puas yog Perovskite Display Technology Hloov ntawm R & D mus rau Kev Lag Luam?

Kev lag luam zaub tau tsom mus rau perovskites vim tias lawv muaj kev sib xyaw ua ke ntawm cov xim purity siab, tunable bandgaps, thiab qis - nqi fabrication.

• Ib txwm ua kua siv lead ua kua tso siab rau cov xim lim rau cov xim hloov, uas ua rau qee qhov tsis pom kev;
• Txawm hais tias RGB ncaj qha- saib LEDs tuaj yeem tso lub teeb ntawm nws tus kheej, cov chips liab, ntsuab, thiab xiav tseem txawv ntawm qhov ua tau zoo, lub neej ntev, thiab tus nqi.
• Perovskites muaj lwm txoj hauv kev thev naus laus zis.
•  

Tam sim no, txoj hauv kev ua tau zoo tshaj plaws rau kev lag luam yog perovskite quantum dot xim hloov tshuab: xiav lub teeb ci ua rau cov khoom siv perovskite, ua rau nws hloov mus rau siab -purity liab thiab ntsuab lub teeb, yog li ua tiav cov xim dav dua thiab cov xim zoo dua.

Qhov tseem ceeb tshaj, perovskite nyob rau hauv txoj kev no tsis tas yuav tsum muaj hluav taws xob ncaj qha rau emit lub teeb, cia nws hla txoj kev sib tw tseem ceeb ntawm kev ua neej tsis txaus ntawm LED; yog li ntawd, nws tau dhau los ua qhov tseem ceeb rau cov tuam txhab nrhiav.

3 Cov Kev Sib Tw Loj Tau Txais Perovskite Display Commercialization

Thaum perovskites tuav cov lus cog tseg zoo, qhov no tsis txhais tau tias lawv tuaj yeem hloov tam sim ntawdOLEDslos yog Micro LEDs.

• Thawj yog qhov teeb meem ntawm lifespan. Perovskites yog cov muaju ionic uas nquag ion tsiv teb tsaws thaum siv hluav taws xob tam sim no; tshwj xeeb, xiav - cov khoom siv lub teeb tseem tsis muaj kev ruaj ntseg txaus. Tam sim no, tseem muaj qhov sib txawv tseem ceeb ntawm chav kuaj- ntsuas lub neej ntev thiab qhov yuav tsum tau ua rau kev lag luam OLEDs ua haujlwm tsis tu ncua rau kaum tawm txhiab teev.
• Qhov thib ob yog qhov teeb meem ntawm txhuas. Feem ntau cov ntaub ntawv perovskite nrog kev ua tau zoo tam sim no muaj cov hmoov txhuas, tab sis cov neeg siv khoom siv hluav taws xob thiab cov khoom lag luam ntsib cov kev xav tau ntxiv rau kev tiv thaiv ib puag ncig, kev nyab xeeb, thiab cov khoom siv rov ua dua tshiab; lead- dawb perovskites tseem xav tau kev txhim kho kev ua haujlwm ntxiv.
• Qhov thib peb yog qhov kev sib tw ntawm loj -scale manufacturing. Kev ua haujlwm siab ua tiav ntawm thaj chaw me me hauv chav kuaj tsis tuaj yeem lav qhov ruaj khov ntawm cov khoom loj ntawm - loj panels. Uniform zaj duab xis deposition nyob rau hauv loj cheeb tsam, khoom stability, yield tus nqi, thiab ntev -lub sij hawm kev cia siab tseem yuav tsum tau ntxiv validation los ntawm kev sim ntau lawm kab.
•  

Yog li ntawd, nyob rau hauv lub sij hawm luv luv, xim hloov thiab quantum dot cov ntaub ntawv tej zaum yuav muaj feem ntau yuav ua tau mus ua lag luam ua ntej tshaj li ncaj electroluminescent LEDs.

Perovskites puas tuaj yeem dhau los ua cov cim tom ntej ntawm LED Zaub?

Kev txiav txim siab los ntawm kev txhim kho kev lag luam tam sim no, cov lus teb yuav tsis yog "kev hloov pauv," tab sis yog "kev koom ua ke."

Nyob rau hauv lub neej yav tom ntej, perovskite muaj feem ntau yuav ua ke ua ntej nrog cov thev naus laus zis xws li Mini LED, Micro LED, quantum dot backlighting, thiab AR cov lus qhia, hais txog qee qhov mob ntawm cov khoom uas twb muaj lawm los ntawm kev txhim kho xim gamut thiab optical efficiency.

Rau kev lag luam LED zaub, dab tsi tiag tiag ua rau perovskite noteworthy tej zaum yuav tsis yog qhov nws tau ua tiav lawm, tab sis yuav ua li cas nws tau nrawm nrawm ntawm qhov sib txawv ntawm "cov txiaj ntsig kuaj- sim- ntsuas ntsuas ntsuas - kev sib koom ua ke rau hauv cov khoom xa khoom."

Txawm li cas los xij, kom txog thaum cov teeb meem cuam tshuam txog kev ua neej nyob, ib puag ncig kev ruaj ntseg, thiab cov txheej txheem tsim khoom loj tau raug daws tiag tiag, perovskite tseem nyob rau theem tseem ceeb ntawm kev tsim khoom lag luam. Rau cov tuam txhab lag luam hauv LED, Mini / Micro LED, backlighting, thiab tom ntej - tiam cov khoom lag luam, nws tam sim no tsim nyog dua los tsom rau lawv cov phiaj xwm thev naus laus zis thiab muab cov hauv kev sib txuas ntau dua li cov ntsiab lus tsis pom kev.

Cov kev hloov kho thev naus laus zis tom ntej no yuav tsis tsuas yog cuam tshuam nrog cov chips me me ntxiv; nws kuj tseem tuaj yeem tshwm sim los ntawm kev rov txhais cov ntaub ntawv lawv tus kheej.
