Xyuas kom meej meej nyob rau hauv lub hnub ncaj qha. Tshawb nrhiav cov qib nit xav tau thiab tiv thaiv -glare nta rau sab nraum zoov LED zaub screen.
Daim phiajcim digital sab nraum zoov tsis muaj txiaj ntsig yog tias cov neeg tuaj saib lub hom phiaj tsis tuaj yeem nyeem cov ntsiab lus kom meej thaum nruab hnub nruab hnub. Ambient tshav ntuj tuaj yeem ntxuav tawm cov qauv hauv hluav taws xob, tig qhov kev tshaj tawm zoo nkauj rau hauv qhov tsis txaus ntseeg, nyeem tsis tau. Cov lus qhia no qhia txog yuav ua li cas los txiav txim siab qhov tseeb qhov ci thiab pom kev teeb tsa rau lub vijtsam sab nraum zoov LED.
Lub tswv yim ntawm Nit Levels thiab Luminance
Txhawm rau sib tw nrog lub hnub, cov duab sab nraum zoov yuav tsum emit lub teeb ntim siab. Hauv kev lag luam zaub kev lag luam, qhov ci ntsa iab yog ntsuas hauvnits(ib metric unit ntawm luminance sib npaug rau ib lub candela ib square meter, $1\\text{nit}=1\\text{cd/m}^2$).
Thaum cov neeg siv khoom hauv tsev TV feem ntau tso tawm ib ncig ntawm 250 txog 400 nits, ib qhosab nraum zoov LED zaub screenyuav tsum ua haujlwm ntawm ntau txhiab tus nits kom nyob twj ywm hauv qab ntuj qhib. Yog hais tias ib qho zaub tsis txaus nit tso zis, ambient nruab hnub nrig yuav overpower lub screen qhov sib piv, ua rau cov ntawv nyeem thiab cov duab tshwm faded.
Application Scenarios thiab Orientation
Qhov tsim nyog brightness tso zis ntau nyob ntawm lub cev orientation ntawm lub vaj huam sib luag zaub thiab tus nqi ntawm cov duab ntxoov ntxoo txhua hnub nws tau txais.
Sab Hnub Tuaj/South-Face Displays:Cov ntxaij vab tshaus no tau ntsej muag ncaj qha, tsis muaj hnub ci rau lub sijhawm ntev thiab yuav tsum muaj cov txiaj ntsig zoo tshaj plaws los tawm tsam qhov ci ntsa iab loj.
Sab qaum teb -Face Displays:Vim tias lawv fim deb ntawm lub hnub ci ncaj qha nyob rau sab qaum teb hemisphere, cov teeb tsa no tuaj yeem ua haujlwm tau zoo nrog me ntsis brightness profiles.
Hauv qab -Canopy lossis Shaded Plazas:Muab tso rau hauv kev tsim vaj tse overhangs, cov lus qhia no fim tsawg ncaj qha glare thiab tuaj yeem siv kev txuag hluav taws xob thiab qib ci.
Cov Ntsiab Lus Pom Zoo thiab Kev Ua Haujlwm
Ua kom pom kev pom zoo nyob rau nruab hnub muaj ntau dua li tsuas yog khiav lub vijtsam ntawm lub zog siab tshaj plaws; nws yuav tsum muaj kev tswj kev ci ntsa iab thiab kev tswj qhov sib txawv ntawm cov qauv.
Tsis Siv Neeg Brightness Dimming
Kev ua haujlwm ntawm lub vijtsam ntawm qhov ci siab tshaj plaws thaum hmo ntuj ua rau pom kev tsis xis nyob rau cov neeg tsav tsheb thiab ua txhaum txoj cai teeb pom kev zoo hauv zos. Txhim khu kev qha systems feature automated brightness tswj siv ambient lub teeb sensors. Cov sensors no nyeem cov teeb pom kev nyob ib puag ncig thiab kho kom zoo ntawm cov khoom tso tawm txhua hnub.
| Lub Sijhawm Hnub / Xwm Txheej | Hom Lub Teeb Nruab Nruab Nruab Nrab | Pom zoo Screen tso zis |
| Nruab Hnub Direct Sunlight | Siab heev | 5,500 – 7,{3}} Nit |
| Overcast / Cloudy Day | Nruab nrab | 2,500 – 4,000 Nits |
| Dusk / Twilight | Tsawg | 1,000-1,500 Nuj |
| Kev ua haujlwm hmo ntuj | Tsawg kawg | 500-800 Nws |
Contrast Enhancement thiab Anti-Glare
Luminance tsuas yog ib nrab ntawm qhov pom kev sib npaug; qhov sib piv piv yog qhov tseem ceeb sib npaug. Sab nraum zoov modules siv lub cev ntxoov ntxoo los yog "louvers" (me me, matte-black yas brims positioned ncaj qha saum toj ntawm txhua kab LED) los cam microscopic ntxoov ntxoo ntawm lub ntsej muag zaub. Qhov kev tsim qauv no ua rau cov qib dub tiag tiag thiab txhim kho kev nyeem tag nrho hauv qhov siab - glare ib puag ncig.
Cov ntsiab lus thiab cov lus pom zoo
Thaum nrhiav qhov screen LED sab nraum zoov, xyuas kom meej tias qhov ci ntsa iab haum rau koj qhov chaw teeb tsa tshwj xeeb. Tsis txhob yuav ib qho qis - lub vaj huam sib luag ci ntsa iab kom txuag tau ntawm cov khoom siv thawj zaug yog tias lub vijtsam yuav muab tso rau hauv qhov ncaj, tsis muaj hnub ci. Nco ntsoov xyuas kom lub kaw lus suav nrog cov khoom siv tsis siv neeg sensor los tiv thaiv cov khoom siv los ntawm kev laus ntxov ntxov thiab ua raws li cov cai hauv cheeb tsam teeb pom kev zoo.
Cov lus nug nquag nug (FAQ)
Kuv xav tau pes tsawg nits rau lub vijtsam hauv lub hnub ncaj qha?
Rau cov lus qhia raug ncaj qha, tsis muaj qhov ntxoov ntxoo thaum tav su, kev lag luam kev paub qhia tau hais tias tsawg kawg ntawm 5,500 nits yuav tsum tau ua kom yooj yim, nrog 7,000 nits lossis siab dua nyiam rau siab - cuam tshuam kev lag luam tshaj tawm.
Puas yog khiav lub vijtsam ntawm qhov ci siab dua ua rau nws lub neej luv?
Yog lawm, khiav diodes ntawm lub peev xwm siab tshaj plaws tsis tu ncua ua kom muaj cua sov ntau ntxiv thiab ua kom lub ntuj degradation ntawm semi-conductors. Siv cov yam ntxwv tsis siv neeg dimming pab txuas ntxiv lub neej los ntawm kev txo cov zis thaum tsaus ntuj.
Qhov txawv ntawm lumen thiab nits yog dab tsi?
Lumens ntsuas tag nrho cov teeb pom kev zoo los ntawm lub teeb ci hauv txhua qhov kev qhia (feem ntau siv rau cov projectors lossis cov teeb pom kev zoo). Nits ntsuas qhov ci ntsa iab tawm ntawm thaj chaw tshwj xeeb hauv ib qho kev taw qhia, ua rau nws qhov kev ntsuas tsim nyog rau cov pav ca - vaj huam sib luag.
High -cov ntxaij vab tshaus sab nraum zoov puas tuaj yeem ua rau muaj kev phom sij rau kev tsheb?
Yog tias sab laug nyob rau nruab hnub ci ntsa iab thaum hmo ntuj, cov ntxaij vab tshaus sab nraum zoov tuaj yeem ua rau tus neeg tsav tsheb dig muag thiab ua rau muaj kev nyab xeeb. Qhov no yog vim li cas lub nroog feem ntau tswj hwm nruj hmo ntuj nit txwv, uas yog tswj tau los ntawm lub teeb sensor controllers.
