(3) Cov tuam txhab thev naus laus zis tau siv zog siv Mini LED backlight LCD
Raws li TechCrunch, xyoo 2014, Apple tau txais LuxVue Technology, lub tuam txhab micro-LED screen. Raws li tsab ntawv ceeb toom hauv Economic Daily, Apple npaj yuav nqis peev kwv yees li NT $ 10 billion (US $ 334 lab) los qhib mini-LEDs thiab micro-LEDs hauv Taiwan. Kev cog qoob loo.
Qee cov kws tshuaj ntsuam tau hais hauv lub Peb Hlis tias Apple npaj yuav tso tawm tsawg kawg rau 6 cov khoom lag luam mini-LED thaum kawg ntawm 2021, suav nrog 14-inch thiab 16-inch MacBook Pro qauv, iMac Pro, 12.{{5} }inch iPad Pro, 10.2-inch iPad thiab 7.9-inch iPad mini .
Thaum Lub Ib Hlis 2018, Samsung tau tso tawm 75-inch 4K Micro LED zaub thiab 219-inch 8K Micro-LED zaub raws li cov qauv sib txuas hauv 2019.
Sony kuj tau qhia txog cov khoom siv lead ua LED sib xws. Raws li ledinside, Huawei cov khoom TV tiam tom ntej yuav tsum tau txais Mini LED backlight technology.
(4) Kev lag luam ntu uas tuaj yeem tawg
Mini LED tau nyiam ntau yam txij li thaum nws pib, thiab nws cov ntawv sau cia tuaj yeem npog ntau thaj chaw xws li RGB cov ntxaij vab tshaus, lub teeb nraub qaum laptop, TV backlights, xov tooj ntawm tes backlights, thiab cov khoom siv tsheb.
1. Mini LED backlight kev lag luam ze rau hauv daim ntawv thov TV loj
Vim tias cov khoom lag luam loj tau txais txiaj ntsig, qhov kev daws teeb meem siab OLED TVs tau ntsib qhov teeb meem ntawm cov nqi siab ntev, thiab cov LEDs mini tuaj yeem ua tiav cov duab nkhaus thiab nqaim-ntev los ntawm qhov chaw tus nqi tsim nyog.
Thiab nws muaj cov yam ntxwv ntawm qhov dav xim gamut, qhov sib txawv siab, thiab nyias profile, yog li nws yuav tsum tau qhia nws cov kev txawj ntse hauv thaj tsam ntawm qhov loj-loj TV backlights, raws li kev txheeb cais los ntawm Aowei Cloud Network. Raws li lub Rau Hli 2018.
Qhov muag loj loj ntawm TVs yog 55 ntiv tes, 32 ntiv tes, thiab 65 ntiv tes, uas qhov loj tshaj plaws yog 65 ntiv tes. Nws tuaj yeem pom tau tias qhov nce ntxiv ntawm qhov screen loj yog qhov tseem ceeb hauv kev txhim kho TV.
Nyob rau hauv kev pom ntawm qhov tshwj xeeb kev zoo ntawm MiniLED backlight daws nyob rau hauv high-txhais cov ntxaij vab tshaus loj, peb ntseeg hais tias nws yuav twv yuav raug hu ua ib tug txawv nyob rau hauv lub teb ntawm loj-loj TVs.
① Mini LED backlight yog ib qho cuab yeej tseem ceeb rau LCD camp tiv thaiv OLED
Txawm hais tias nyob rau hauv kev sib ntaus sib tua rau lub lag luam high-end zaub, OLED ib zaug tshem tawm qee qhov ntawm LCD ua lag luam nrog nws cov ntsiab lus siab, zoo, thiab cov yam ntxwv zoo sib xws, thiab nws yog ib qho tsis muaj kawg. Txawm li cas los xij, nrog rau qhov sib ntxiv ntawm mini LED thev naus laus zis, cov nyhuv ntawm cov tshuaj LCD tsis zoo dua;
Tsis tas li ntawd, txij li thaum yug los ntawm OLED thev naus laus zis, qhov kev thuam dav dav ntawm tus nqi siab thiab cov teeb meem tsis muaj sia nyob tsis tau daws tau zoo. Qhov no tau muab lub LCD camp ib qho kev ua tau zoo hauv kev rov qab mus rau lub lag luam high-end zaub.
Tsis tas li ntawd, peb pom tias kev lag luam hauv tsev LCD thiab LED tau dhau los ua kev paub tab, thiab cov khoom lag luam tau txuas ntxiv txo qis; Yog li ntawd, muaj laj thawj ntseeg tias mini LED ntxiv rau LCD zaub daws yuav tsum ua kom muaj kev sib luag nyob rau yav tom ntej, los ntawm kev nkag siab siab rau cov pej xeem.
② Lub sijhawm ntawm "Ultra HD" zaub yog los, thiab kev txhim kho ntawm lub teeb rov qab ua rau qhov kev thov rau Mini LED
Thaum pib ntawm 2019, Ministry of Industry thiab Information Technology, Lub Xeev Kev Tswj Xyuas Xov Tooj Cua thiab TV thiab Central Xov Tooj Cua thiab TV General Chaw Nres Tsheb tau koom ua ke "Ultra HD Video Industry Development Action Plan 2019-2022).
Raws li cov kev qhia tag nrho ntawm "4K ua ntej, coj mus rau hauv tus account 8K", txhawb kev tsim kho ntawm ultra-high-txhais video kev lag luam thiab kev siv hauv cov haujlwm muaj feem xyuam.
4K thiab 8K TVs muab tso rau cov kev xav tau tshiab rau siab dynamic ntau yam (HDR), siab xim gamut, siab sib piv, siab teeb efficiency, thiab siab daws teeb meem. Yog li ntawd, kev tsim kho tshiab ntawm LED backlight technology thiab cov khoom lag luam yog qhov tseem ceeb heev.
Kev siv cov ntaub ntawv fluorescent tshiab (xws li nqaim emission spectrum phosphors, quantum dots) thiab ntim tshuab tshiab kom ua tiav cov xim gamut siab ntawm high-txhais TV. Tib lub sijhawm, HDR lossis hauv zos dimming thev naus laus zis ntawm lub teeb nraub qaum yog siv.
Kev paub txog qhov kev thov rau qhov sib txawv siab muaj kev nthuav dav dav. Los ntawm 2020, nws cia siab tias kev muag khoom ntawm 4K TV terminals uas ua tau raws li qhov yuav tsum tau muaj yuav suav txog ntau dua 40 feem pua ntawm tag nrho TV muag.
Los ntawm 2022, lub ntiaj teb nkag mus rau 4K TVs yuav ntau dua 70 feem pua, sib xws rau kev muag khoom ntawm 175 lab 4K TVs, thiab kev muag khoom ntawm 8K TV terminals yuav suav txog ntau dua 5 feem pua ntawm tag nrho TV muag.
Nyob rau tib lub sijhawm, qhov loj dua qhov loj ntawm LCD npo, qhov loj ntawm cov khoom siv LED xav tau los ntawm lub teeb pom kev zoo thiab qhov loj dua qhov loj, uas yuav tsav qhov kev thov rau LEDs ntau dua.
③Internet ntawm Txhua yam qhib qhov chaw rau kev loj hlob ultra-high-txhais zaub
Nyob rau hauv nruab nrab thiab ntev, nrog rau kev ua kom zoo ntawm tib neeg lub neej thiab kev tswj cov txheej txheem ntau lawm, kev ua lag luam yuav tsum tau ua kom pom tseeb ntxiv mus ntxiv, thiab kev nkag mus ntawm qhov me me thiab Mini LEDs tau dhau los ua ntau dua.
Nyob rau tib lub sij hawm, nyob rau hauv lub era ntawm Internet ntawm txhua yam, ntse terminals yuav qhia ib tug spurt ntawm txoj kev loj hlob, thiab yuav muaj ntau thiab ntau lub davhlau ya nyob twg tso saib lub sij hawm thiab platforms, uas yuav kuj zoo heev nthuav qhov chaw loj hlob ntawm ultra-high-txhais. tso saib.
