I. Cov thev naus laus zis thev naus laus zis rau xim luam tawm hauv cov duab LED
1. Xim Gamut Kev Pabcuam
- Mainstream LED cov ntxaij vab tshaus txais cov qauv xim gamut dav (xws li DCI-P3 thiab Adobe RGB), ua tiav qhov kev pab them nqi ntawm 90%-98% (cov ntaub ntawv qhov chaw: TÜV Rheinland 2023 qhia). Piv txwv li, Samsung's Micro LED series muaj DCI-P3 kev pab them nqi ntawm 97%, mus txog xinesmas-qib xim qauv.
- Ordinary sRGB xim gamut tsuas yog npog li ntawm 70% ntawm cov xim pom ntawm tib neeg lub qhov muag, thaum lub ntsej muag dav xim gamut tuaj yeem tsim cov xim liab thiab ntsuab ntau dua, tsim rau cov xwm txheej xws li zaj duab xis thiab TV tshaj tawm- ntau lawm.
2. Xim Accuracy Parameter (ΔE)
- ΔE tus nqi ntsuas xim sib txawv. ΔE Tsawg dua lossis sib npaug rau 1.5 yog suav tias yog qib tshaj lij- qib (xws li Sony BVM-HX310 siv saib), thiab ΔE Tsawg dua lossis sib npaug rau 3 raws li cov qauv tsim. Cov khoom lag luam muaj siab -kawg LED cov ntxaij vab tshaus (xws li LG OLED EVO) muaj qhov nruab nrab ΔE ntawm 1.2.
- Cov neeg tsim khoom txhim kho xim raug los ntawm nti- theem calibration (xws li lub vijtsam- los ntawm -screen calibration ntawm Apple's Pro Display XDR), tab sis ntev - siv sij hawm ntev yuav ua rau ΔE nce vim LED degradation. II. Cov ntsiab lus tseem ceeb cuam tshuam rau xim luam tawm
1. Kho vajtse Configuration
- LED Chip Hom: Mini LED backlighting (xws li 12.9-nti iPad Pro) muaj 2596 dimming zones thiab qhov sib piv ntawm 1,000,000: 1, muab kev tswj xyuas meej dua ntawm qhov ci thiab tsaus dua li cov LEDs ib txwm muaj.
- Tsav IC Performance: 16-ntsis greyscale ua ICs (xws li Novatek NT72671) tuaj yeem tso saib 281 trillion xim, txo cov xim banding.
2. Ib puag ncig thiab Calibration
- Ambient Light muaj qhov cuam tshuam loj: Ntawm 500 lux illuminance, xim txawv ΔE tuaj yeem nce 2-3 (cov ntaub ntawv los ntawm: SID 2022 txoj kev tshawb fawb). Nws raug nquahu kom siv lub teeb thaiv lub teeb lossis lub teeb pom kev nyob ib puag ncig (xws li Dell UltraSharp UP3221Q).
- Qhov Tseem Ceeb ntawm Kev Ntsuas Xim Xim: Cov neeg siv khoom tshaj lij yuav tsum ntsuas txhua hli nrog lub ntsuas xim (xws li X-Rite i1Pro 3), thaum cov neeg siv khoom- cov khoom qib tau pom zoo kom ntsuas txhua rau lub hlis.
III. Kev lag luam daws teeb meem thiab yav tom ntej Trends
1. Kev tawg hauv HDR Technology
- HDR10+ thiab Dolby Vision optimize qhov ci ntsa iab / xim kub ntawm txhua tus ncej los ntawm dynamic metadata. LED cov ntxaij vab tshaus nrog lub teeb ci siab tshaj 1000 nits (xws li TCL X11G) tuaj yeem tsim cov ntsiab lus tseem ceeb xws li hnub ci cov ntsiab lus.
2. AI xim tswj
- Cov qauv zoo li Hisense U8H tau nruab nrog lub cav AI uas txheeb xyuas cov ntsiab lus (xws li cov yeeb yaj kiab / kev ua si) hauv lub sijhawm tiag tiag thiab phim cov xim gamut. Hauv sRGB hom, ΔE tuaj yeem tswj tau hauv 1.8.
3. Lub peev xwm ntawm Micro LED
- Tus kheej-emissive Micro LEDs (xws li Sony CLEDIS) tsis xav tau cov ntxaij lim dej, muab 40% xim purity siab dua, thiab muaj lub neej ntev tshaj 100,000 teev. Txawm li cas los xij, lawv cov nqi tam sim no yog 5-8 npaug ntawm cov tsoos LEDs (cov ntaub ntawv qhov chaw: DSCC 2023).
Cov ntsiab lus: Cov xim muaj peev xwm rov ua dua tshiab ntawm LED siab - cov lus txhais tau nce mus txog qib kev tshaj lij- qib yuav tsum tau ua, tab sis kev ua haujlwm kho vajtse, kev siv ib puag ncig, thiab cov nqi tu yuav tsum tau txiav txim siab. Nyob rau hauv lub neej yav tom ntej, nrog rau kev tsim khoom loj ntawm Micro LEDs thiab kev siv dav dav ntawm AI algorithms, kev tsim cov xim xim yuav raug txhim kho ntxiv.
