P0.9 COB Mini / Micro LED Zaub yog cov khoom lag luam paub tab, uas tau tsim tawm ntau
Nyob rau hauv 2019, lub peev xwm ntau lawm ntawm cov lus qhia hauv qab P0.9 tseem yog qhov txwv.Ntawm qhov tod tes, qhov kev thov kev lag luam kuj tsis tshua muaj, thiab kev txhawb nqa ntawm cov saw hlau lag luam kuj tsis txaus.
Los ntawm 2021, nrog rau kev nce qib ntawm ntim tshuab, kev txhim kho kev ua tau zoo, thiab txo tus nqi sai ntawm LED chips, thiab lwm yam, qhov kev thov rau cov khoom qis dua P1.0 yuav maj mam dhau los ua lag luam nrov, thiab Mini LED cov khoom tseem yuav nkag mus rau cov khoom lag luam. high-end kev ua lag luam mus rau nruab nrab-rau-high-end kev ua lag luam, los ntawm kev tshaj lij kev lag luam rau cov khoom lag luam thiab tom qab ntawd mus rau pej xeem kev lag luam, nws tau hloov pauv ib kauj ruam.
Los ntawm 2022, nyob rau hauv cov nqe lus ntawm ntim daim ntawv, txawm nws yog COB, plaub-hauv-ib, los yog ob-hauv-ib, nws tsis yog ib qho teeb meem rau cov khoom siv ntawm P0.9mm diode, thiab ob qho tib si muaj peev xwm thiab yield tuaj yeem ua tau. lav.
Txawm li cas los xij, vim yog cov nqi, los ntawm kev ua lag luam me me tam sim no, cov khoom lag luam ntawm P0.9 tseem tseem muaj kev sib tham hauv qee lub rooj sib tham, kev hais kom ua thiab saib xyuas chav haujlwm ntawm tsoomfwv lossis cov tuam txhab loj hauv xeev, thiab P1.2- P1.5 tseem yog qhov tseem ceeb ntawm kev lag luam me me..
Tab sis qhov xwm txheej no tau txhim kho, thiab daim ntawv thov scenarios ntawm P0.9 Mini ncaj qha cov khoom lag luam tau nthuav dav tas li.
Lub suab nyob ib ncig ntawm P0.7 LED zaub yuav dhau los ua qhov tseem ceeb ntawm cov tiam tom ntej.
P0.7mm tuaj yeem tau txais 4K daws teeb meem rau 100-200 nti npo
Qhov loj ntawm 100-200 ntiv tes yog qhov tshiab loj loj daim ntawv thov kev lag luam rau cov lus qhia me me.
Vim tias kev ua lag luam siab dua 200 ntiv tes twb tau nyob los ntawm cov tsoos P1.2 ~ 2.5mm me me-pitch LED cov lus, thiab qhov me me me me yog feem ntau 98-nti LCD TV khoom, tam sim no tus nqi qis tshaj yog tsawg dua 3,000 USD, thiab cov zaub cov nyhuv kuj kuj zoo.Lub suab zoo LED zaub yog qhov nyuaj rau kev sib tw nrog LCD hauv 98-nti ua lag luam.
Txawm li cas los xij, qhov loj me ntawm lub vijtsam LCD yog qhov nyuaj rau kev ua txhaum ntawm 100-nti txwv.Cov kev sib tw ib txwm muaj rau 100-200-nti cov lus qhia feem ntau yog qhov kev tshaj tawm-txawm li cas los xij, zoo-pitch LED cov ntxaij vab tshaus loj muaj qhov pom kev zoo dua nyob rau hauv lub zog "lub teeb."
Feem ntau ntawm 100-200-nti kev lag luam suav nrog chav sib tham, kev lag luam, kev tshaj tawm, thiab lwm yam xwm txheej, uas yuav tsum muaj teeb pom kev zoo dua.
Thiab nyob rau hauv 100-200 nti ua lag luam, me me-pitch LED zaub kuj fim qhov yuav tsum tau los sib piv PPI daws teeb meem nrog LCD zaub.
Vim tias daim ntawv thov 100-200-nti sib haum rau qhov ze tshaj plaws saib qhov deb ntawm 3-7 meters, lossis txawm tias ze dua qhov pom kev deb.Qhov kev pom ze dua ua kom pom cov duab zoo, tab sis kuj yuav tsum tau "siab dua PPI daws teeb meem", uas yog, yuav tsum muaj qhov me me pixel suab.
Cias muab tso, 75-98-nti LCDs twb tiav 4K daws teeb meem;qhov kev daws teeb meem ntawm 100+ high-txhais LED cov ntxaij vab tshaus tsis tuaj yeem ua phem dhau.
P0.7 qhov taw qhia tuaj yeem muab 4K daws teeb meem ntawm 120-nti +, uas yog raws nraim qhov kev daws teeb meem ntawm cov kev siv suab-visual tam sim no thiab loj dua li 98-nti LCD.
Nyob rau hauv no hais txog, ib qho piv txwv yog hais tias tam sim no pixel suab ntawm mainstream LCD TVs nyob nruab nrab ntawm 0.3 thiab 0.57 hli.Nws tuaj yeem pom tau tias qhov me me-pitch LED npo qhov sib nrug ntawm P0.7 hli tuaj yeem txuas tau zoo dua rau daim ntawv thov kev paub ntawm LCD saib, thiab muab cov khoom sib txawv hauv qhov loj ntawm 100-200 ntiv tes.
Yog li ntawd, los ntawm kev ua lag luam xav tau qhov loj me thiab kev daws teeb meem, nws tuaj yeem pom tias P0.7 yuav dhau los ua cov cim tseem ceeb ntawm micro-pitch LED cov ntxaij vab tshaus.
Tab sis txoj kev loj hlob ntawm P0.7 100-200 nti zaub lag luam xav tau tus nqi zoo dua tam sim no.Hauv qhov no, me me-pitch LEDs tau nce zuj zus los ntawm kev sib sau ua ke ntawm cov kev paub dhau los thiab kev txhim kho cov khoom lag luam.Tshwj xeeb tshaj yog nyob rau hauv peb lub xyoos dhau los, P0.9 cov khoom tau ua tiav ib qho kev vam meej hauv kev ua lag luam siab, thiab tus nqi tau nqis los ntawm 30%.Cov kws tshuaj ntsuam xyuas kev lag luam ntseeg tias P0.7 cov khoom lag luam yuav tsum nyob ntawm tus nqi tib yam li cov khoom lag luam P0.9 ua ntej.
Kev lag luam cia siab tias nyob rau hauv ob xyoos tom ntej no, kev lag luam kev lag luam ntawm cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob xws li mini LED chips, thiab lwm yam, yuav tau txais kev txhim kho zoo heev, thiab qib ntawm cov khoom siv thev naus laus zis thiab cov txheej txheem tsim khoom kuj tseem yuav txhim kho tau zoo.Kev lag luam kev lag luam tab tom ntsib ib puag ncig Muaj peev xwm txo tus nqi.Qhov no kuj yog "lub sijhawm zoo" rau kev teeb tsa ntawm lub cim tshiab ntawm "P0.7 suab" cov khoom.
Daim ntawv thov 100-200-nti yog qhov "tshiab scenario" uas ntsuas kev lag luam thev naus laus zis thiab kev tswj hwm tus nqi.
Tau kawg, cov tuam txhab sib txawv kuj tseem yuav hloov kho kom pom lawv tus kheej cov khoom zoo: piv txwv li, txhawm rau txo cov nqi thiab cov teeb meem, cov tuam txhab tuaj yeem muab 136-nti 4K cov khoom lag luam nrog me ntsis loj dua pixel suab;los yog muab 4K daws teeb meem rau cov khoom me me, xws li Samsung Phab ntsa siv 0.63mm suab.
