Linewidth faib ntawm ntau yam inkjet luam ntawv thev naus laus zis
Tam sim no, ob lub thev naus laus zis thev naus laus zis, cov kua siv lead ua kua (LCD) thiab cov khoom siv hluav taws xob hluav taws xob hluav taws xob (OLED), tau siv rau ze-qhov muag pom (NEDs) thiab lub taub hau-mounted zaub (HMDs).Txawm li cas los xij, kev tsim cov thev naus laus zis tshiab tau nrawm dua vim qhov tsis zoo xws li kev hloov pauv tsis zoo, xim saturation, thiab kev laus sai thiab luv luv lifespan.
Nrog zoo heev optical kev ua tau zoo thiab ntev lifespan,Micro LEDraug suav hais tias yog qhov kawg ntawm cov khoom siv thev naus laus zis tom ntej.Qhov tsawg kawg nkaus pixel loj mus txog kaum tawm microns, thiab qhov siab pixel ceev ua rau nws siv tau rau hauv AR / VR.
Nrog rau kev txhim kho sai ntawm kev txawj ntse, kev paub txog duab thiab 5G kev sib txuas lus thev naus laus zis, augmented reality (AR) thiab virtual reality (VR) thev naus laus zis tau txhim kho ntawm qhov txaus ntshai.Nyob rau hauv cov ntsiab lus ntawm tus kab mob tshiab, kev sib txuas lus thiab kev sib txuas lus ntawm cov neeg siv khoom nyob deb tau nce, thiab kev ua lag luam tau rov qab xav txog AR / VR, thiab kev nqis peev hauv kev siv thev naus laus zis tau nce ntxiv.
Raws li IDC, los ntawm 2020 txog 2024, kev lag luam loj ntawm lub ntiaj teb no AR thiab VR kev lag luam yuav loj hlob los ntawm 28 billion yuan thiab 62 billion yuan mus rau 240 billion yuan, feem.Ib qho ntawm cov laj thawj tseem ceeb rau kev ua lag luam tawg yog kev tawg ntawm cov cuab yeej tshiab nrog kev ua tau zoo.Raws li lub hauv paus ntsiab lus ntawm AR / VR, cov khoom siv yuav tsum muajultra-siab pixel ceevthiab ceev refresh ceev ntxiv rau lub teeb yuag thiab me me.
Daim ntawv no ua ntej qhia txog kev tshawb fawb txog kev ua tiav ntawm AR / VR thev naus laus zis, thiab tom qab ntawd tham txog kev tshawb fawb kev nce qib ntawm MicroLED zaubthev naus laus zis thiab nws qhov kev hloov pauv hauv AR / VR, nrog rau qhov zoo ntawm kev npaj Micro LED xim hloov txheej txheej los ntawm inkjet luam ntawv thev naus laus zis.Cov tsis-radiative zog hloov mechanism thiab cov nyhuv ntawm thickness ntawm cov xim hloov xim txheej ntawm cov xim conversion efficiency;lub superiority ntawm SIJ nyob rau hauv kev daws teeb meem piv rau lwm yam printing technologies yog qhia.
Cov ntawv thiab lub tsev kawm ntawv lub logo luam tawm los ntawm SIJ thev naus laus zis
Ntxiv rau qhov siab pixel ceev, cov xim puv kuj yog lub hauv paus tseem ceeb kom paub txog Micro LED hauv AR / VR.Ntawm lawv, cov tswv yim hloov xim yog ib txoj hauv kev zoo kom ua tiav cov xim tag nrho.Quantum dots tau tso rau xiav lossis ultraviolet Micro LED chips los ntawm inkjet luam ntawv thev naus laus zis.Peb-xim luminescence tau ua tiav, thaum zam kev hloov pauv loj heev.
Nyob rau hauv xyoo tas los no, thev naus laus zis xws li piezoelectric / thermal inkjet luam ntawv, aerosol inkjet luam ntawv, electrohydrodynamic inkjet luam ntawv, thiab super inkjet luam ntawv tau siv los tso cov xim hloov xim, uas qhia tau zoo rau kev ua tiav cov xim Micro LEDs.Tsis ntev los no, pab neeg ntawm Prof. Zhang Rong los ntawm Xiamen University, nrog kev koom tes nrog Prof. Guo Haozhong los ntawm Taiwan Chiao Tung University, tau luam tawm ib daim ntawv hu ua "Principle of Inkjet Printing Technology and Its Application in AR/VR Microdisplays" in Opto-Electronic Advances Nqe 5, 2022 "Ib tsab ntawv tshuaj xyuas.
Qhov thib ob qhia txog cov txheej txheem luam ntawv ntawm ntau yam inkjet luam ntawv thev naus laus zis, thiab ob qhov teeb meem tseem ceeb: kev ua kom zoo ntawm rheological tsis ntawm number case thiab kev daws rau lub nplhaib kas fes.
Cov kev ntsuas rheological ntawm tus number case haum rau txhua lub tshuab luam ntawv thiab kev cuam tshuam ntawm rheological tsis nyob rau hauv cov nyhuv luam ntawv tau qhia.Ob txoj kev daws teeb meem rau lub nplhaib kas fes thiab cov kev txhim kho tshwj xeeb raug tshuaj xyuas.Thaum kawg, qee qhov teeb meem muaj feem cuam tshuam nrog cov txheej txheem xim hloov pauv tau hais txog, suav nrog optical crosstalk, lub teeb xiav nqus, thiab cuam tshuam rau nws tus kheej.
Micro LED pave txoj hauv kev rau kev lag luam ntawm AR / VR, thiab kev tsim cov xim tag nrho Micro LED nrog siab pixel ceev yog ib qho ntawm cov fwj.Lub tswv yim hloov xim txheej txheej txheej txheem yog ib txoj hauv kev zoo kom paub cov xim tag nrho Micro LED, thiab kev tsim cov tshuab luam ntawv inkjet muab kev txhawb nqa rau kev npaj ntawmkev daws teeb meem siabxim hloov khaubncaws sab nraud povtseg.
