Nrog kev txhim kho cov thev naus laus zis thev naus laus zis, LEDs tau siv ntau thiab ntau dua hauv cov xwm txheej loj hauv TV studios thiab tshaj tawm hauv TV. Raws li cov txheej xwm keeb kwm yav dhau phab ntsa, nws muab ntau yam ntawm cov duab tom qab zoo nkauj thiab ntxim nyiam thiab muaj kev sib tham ntau dua. Lub vijtsam tom qab kuj tseem txav mus thiab zoo li qub, kev ua tau zoo thiab keeb kwm yav dhau los tau ua ke, thiab huab cua ntawm qhov chaw thiab qhov haujlwm tau ua tiav zoo kawg nkaus, thiab kev ua haujlwm thiab kev cuam tshuam uas lwm yam khoom siv kos duab nyuaj nyuaj kom ua tiav. Txawm li cas los xij, yog tias koj xav ua kom tau zoo dua ntawm cov zaub LED, koj yuav tsum xyuam xim rau cov hauv qab no hauv kev xaiv thiab siv cov txheej txheem:
1. Qhov kev tua yuav tsum tsim nyog
Raws li tau hais hauv qhov kev sib tham yav dhau los hais txog dot suab thiab qhov ua kom puv, LED cov ntxaij vab tshaus nrog cov suab sib txawv thiab qhov sib txawv ntawm qhov ua kom muaj qhov sib txawv ntawm kev tua. Coj lub teeb pom kev zoo nrog qhov pom ntawm 2.5 mm thiab qhov ua tiav ntawm 60% ua piv txwv. Qhov nrug ntawm tus neeg raug yees duab thiab lub vijtsam yog 4-10 meters, yog li koj tuaj yeem tau txais daim duab keeb kwm yav dhau zoo dua thaum tua tib neeg. Yog tias tus neeg nyob ze rau ntawm lub vijtsam, thaum txhaj tshuaj tiv thaiv kab mob tom qab, cov keeb kwm yav dhau yuav tshwm sim me me, thiab nws yooj yim los tsim kev cuam tshuam ntawm moiré.
2. Dot spacing yuav tsum me me li sai tau
Lub suab teev yog qhov nrug nruab nrab ntawm cov ntsiab lus nruab nrab ntawm cov pixels uas nyob ib sab ntawm lub vijtsam LED. Qhov me me ntawm lub suab, ntau lub pixels hauv ib cheeb tsam, qhov kev daws teeb meem siab dua, ze dua qhov kev ncua deb tuaj yeem ua tau, thiab tau kawg nws kim dua. Tam sim no, dot suab ntawm cov ntxaij vab tshaus LED siv hauv TV hauv tsev studios feem ntau yog 1.2-4 hli. Nws yog qhov yuav tsum tau ua tib zoo kawm txog kev sib raug zoo ntawm qhov kev daws teeb meem ntawm lub teeb liab thiab lub suab teev, thiab siv zog ua kom tau qhov kev daws teeb meem tib yam kom ua tiav cov ntsiab lus-rau-taw qhia, thiaj li ua tiav qhov txiaj ntsig zoo tshaj plaws.
3. Kev hloov xim kub
Thaum lub studio siv lub vijtsam LED ua keeb kwm yav dhau, nws qhov kub thiab txias xim yuav tsum zoo ib yam nrog cov xim kub ntawm lub teeb hauv chav ua yeeb yaj kiab, yog li ntawd qhov tseeb luam tawm xim tuaj yeem tau txais thaum tua. Raws li qhov xav tau ntawm txoj haujlwm, lub teeb pom kev zoo qee zaum siv 3200K cov xim kub tsis muaj xim, qee zaum 5600K cov xim kub kub, thiab cov duab LED xav tau hloov kho kom haum rau cov xim kub kom tau txais cov txiaj ntsig kev tua.
4. Ua kom muaj chaw siv tau zoo
Lub neej thiab kev nyab xeeb ntawm lub vijtsam LED cuam tshuam nrog kev ua haujlwm kub. Yog tias qhov kub ua haujlwm tiag tiag tshaj qhov tau teev tseg siv ntau ntawm cov khoom, tsis tsuas yog nws lub neej yuav luv dua, tab sis cov khoom nws tus kheej kuj tseem yuav raug mob hnyav. Ib qho ntxiv, qhov kev hem thawj ntawm hmoov av tsis tuaj yeem tsis quav ntsej. Cov hmoov av ntau dhau yuav ua rau lub thermal thermal ruaj khov ntawm lub vijtsam coj los yog txawm tias ua rau lub qhov hluav taws xob tuaj, uas tuaj yeem ua rau kub hnyiab thaum raug mob hnyav; hmoov av tseem yuav nqus cov dej noo, uas yuav ua rau hluav taws xob hluav taws xob tawg thiab ua rau qee qhov teeb meem luv luv uas tsis yooj yim rau teeb meem. Yog li ua tib zoo saib xyuas kom lub studio huv.
Lub vijtsam LED tsis muaj nqaws, uas tuaj yeem ua rau daim duab zoo dua; nws muaj qis zog noj, tsawg dua cua sov, txuag hluav taws xob thiab tiv thaiv ib puag ncig; nws muaj qhov sib xws zoo, tuaj yeem ua kom pom qhov tsis sib txawv ntawm cov duab; lub txee me me yog qhov me me, uas yooj yim rau lub vijtsam tom qab los ua lub ntsej muag du Cov xim gamut kev pab them nqi siab dua li ntawm lwm cov khoom lag luam; nws muaj qhov zoo ntawm qhov ua kom muaj zog zoo dua qub, thiab muaj kev ntseeg siab rau kev ua haujlwm thiab tus nqi qis ntawm kev ua haujlwm thiab kev saib xyuas.
