Ib tus neeg yuav khoom tsis ntev los no piv ob nqe lus rau tib 100 m² sab nraum daim ntawv tshaj tawm. Ib tug muab 5,500 nits; lwm tus tau cog lus 8,000. Lub vijtsam pheej yig dua zoo li pheej hmoo, tsis tau "ci" ib qho nqi 18% ntau dua. Qhov kev xaiv twg ua rau muaj kev nkag siab? Brightness yog qhov kev nkag siab tsis zoo tshaj plaws hauv kev muag khoom ntawm LED. Tsawg dhau, thiab koj lub vijtsam ntxuav tawm hauv qab tshav ntuj ncaj qha. Ntau dhau lawm, thiab koj hlawv lub zog, ua kom lub neej ntev ntawm LED, thiab nce koj cov peev nyiaj kom tsis pom qhov nce. Kab lus no piav qhia txog qhov ntsuas qhov ntsuas tiag tiag, qhov teeb pom kev zoo li cas txiav txim siab koj qhov yuav tsum tau ua, thiab tsib txoj cai siv tau uas pab koj ua kom pom kev ci ntsa iab rau koj qhov kev teeb tsa tiag tiag - tsis yog rau daim ntawv muag.
Dab tsi "Nits" Tiag tiag ntsuas
Ib tug nit sib npaug ib lub candela ib square meter (cd/m²) - lub luminance ib tug tib neeg qhov muag perceives los ntawm ib tug screen nto. Tsis zoo li lux, uas ntsuas lub teeb poob rau saum npoo, nits piav qhia lub teeb los ntawm nws. Qhov kev sib txawv ntawd tseem ceeb thaum sib piv cov lus qhia tshwj xeeb, vim tias cov zaub ntsuas ntawm 6,000 nits ncov tuaj yeem txhawb nqa qis dua hauv kev ua haujlwm tas mus li. Cov neeg muag khoom feem ntau hais qhov ci ci siab tshaj plaws; Txawm li cas los xij, tiag tiag- lub ntiaj teb kev nyeem tau nyob ntawm cov khoom tsim tawm tom qab teev cov cua sov. Raws li txoj cai ntawm tus ntiv tes xoo, cia siab tias 15-25% degradation los ntawm cov ntawv xov xwm ib zaug thermal sib npaug mus txog.
Pom zoo Brightness los ntawm Daim Ntawv Thov
Ambient teeb yog qhov kev txiav txim siab sib txawv. Hauv chav sib tham tsis pom kev, ib qho dhau - lub vijtsam ci ua rau qhov muag pom; nyob rau sab qab teb -faus rau saum ru tsev, ib qho hauv qab - ci ntsa iab ploj thaum tav su.
| Daim ntawv thov | Hom Ambient Condition | Pom zoo Brightness |
|---|---|---|
| Sab hauv chav sib tham / khw muag khoom | Tswj teeb pom kev zoo | 600-1,200 nits |
| Sab hauv tsev me me pixel suab / tswj chav | Tsawg ambient | 300-800 hli |
| Kev xauj tsev (theem, txheej xwm) | Mixed theem teeb pom kev zoo | 800-1,500 nits |
| Sab nraum zoov xauj / mobile tsheb | Hnub-rau- hmo ntuj hloov | 4,000-5,500 nits |
| Sab nraum zoov tsau, ntxoov ntxoo los yog sab qaum teb-fab | Ib nrab hnub ncaj qha | 5,000-6,500 nits |
| Sab nraum zoov tsau, tag nrho ncaj qha tshav ntuj | Hnyav ncaj qha tshav ntuj | 6,500-10,000 nits |
Nco ntsoov tias cov kab no xav tias LEDs zoo thiab tsim thermal tsim. Lub txee txias tsis zoo tuaj yeem poob qhov ci ntau dua li lub rooj nyiaj rau.
5 Txoj Cai Brightness
Txoj Cai 1: Match Ambient Light Ua ntej, Tom qab ntawd Pixel Pitch
Ntau tus neeg yuav khoom kho ntawm pixel suab ua ntej ci. Nyob rau hauv kev xyaum, ambient tej yam kev mob los ua ntej: ib tug P2.6 sab hauv tsev screen ntawm 800 nits yeej ib tug "ci" qauv uas blinds viewers nyob rau hauv ib tug dim chaw tos txais. Ntxiv mus, zoo -pitch cov khoom siv sab hauv tsev feem ntau yog tsim los rau qis luminance - thawb lawv ntau dua shortens LED lub neej.
Txoj Cai 2: Nug kom muaj kev ci ntsa iab, Tsis yog Peak
Nug cov neeg muag khoom kom qhia meej qhov ci ntawm qhov dawb, 100% ABL xiam oob qhab, tom qab 60 feeb ntawm kev ua haujlwm. Tsis tas li ntawd, thov cov kev xeem hauv kev sau ntawv. Ib tug loj chaw tsim tshuaj paus yuav teb tsis muaj hesitation; evasive teb yog lawv tus kheej cov ntaub ntawv.
Txoj Cai 3: Txheeb xyuas Auto-Brightness Sensors
Lub vijtsam sab nraum zoov khiav ntawm 7,000 nits thaum ib tag hmo nkim zog thiab ua rau cov neeg nyob ze - thiab hauv qee lub nroog, ua txhaum txoj cai teeb pom kev zoo. Tsis siv neeg brightness sensors kho cov zis rau ambient lub teeb, txiav lub zog noj los ntawm 20-40% thiab txuas ntxiv LED lub neej. Paub meej tias lub sensor ships txheem, tsis yog kev xaiv.
Txoj Cai 4: Txuas Brightness rau Greyscale
Brightness yam tsis muaj grayscale tswj ua tau ntxuav - tawm cov duab. Ob lub vijtsam tuaj yeem ntaus 6,000 nits, tab sis qhov zoo dua grey- nplai ua haujlwm (14-ntsis lossis siab dua) muab cov duab tsaus thiab duab ntxoov ntxoo zoo dua. Yog li ntawd, ib txwm ntsuas cov duab qis qis zoo thaum lub sijhawm ua yeeb yam nyob, tsis yog qhov siab tshaj plaws ntawm daim duab.
Txoj Cai 5: Tsis txhob them rau Nits uas koj tsis pom
Ntxiv ci ntsa iab dhau qhov koj ib puag ncig qhov yuav tsum tau muab xoom pom kev rov qab thaum nce lub zog kos, lub txee rau cua sov, thiab tag nrho cov nqi ntawm cov tswv cuab. Hloov chaw, nqis peev qhov sib txawv hauv LEDs zoo dua, tsim kom muaj cua txias dua, lossis kev tiv thaiv ntev dua - hloov kho koj yuav pom txhua hnub.
Common Buying yuam kev
- caum tus lej siab tshaj."Ntau nits" suab zoo, tsis tau overspecification yog qhov yuam kev kim tshaj plaws hauv kev xaiv qhov ci.
- Tsis quav ntsej calibration.Uncalibrated brightness drifts unevenly hla qhov screen hauv lub hlis, tsim thaj ua rau pom.
- Hla ntawm -site tej yam kev mob.Lub vijtsam tig mus rau sab qaum teb ua qhov txawv ntawm ib qho tig mus rau sab hnub poob mus rau yav tav su hnub - kev taw qhia hloov txhua yam.
- Tso siab rau daim ntawv qhia cov duab nkaus xwb.Thib peb-cov ntaub ntawv xeem tog lossis kev sim ua yeeb yaj kiab nyob hauv lub Hoobkas muaj nqis ntau dua li daim ntawv thov.
Kev xaus thiab cov kauj ruam tom ntej
Kev xaiv ci ntsa iab kawg los ntawm kev sib raug zoo ncaj ncees: koj qhov chaw ib puag ncig lub teeb, koj cov ntsiab lus, koj cov peev nyiaj. Qhia kom muaj kev ci ntsa iab, hais kom nws pib- dimming, thiab kho lub ncov siab ua ib qho tseem ceeb ntawm ntau yam tsis yog tus lej xov tooj. Ua raws li tsib txoj cai no, feem ntau cov neeg yuav khoom pom tias lawv xav tau qhov ci ntsa iab tsawg dua li qhov lawv xav tau - thiab tuaj yeem hloov cov peev nyiaj ntawd mus rau qhov zoo uas qhia tau hais tias.
