Hauv kev sib txuas lus ntawm kev sib txuas lus, muaj ib txwm muaj kev sib cav txog cov cuab yeej no zoo dua, tau coj lossis LCD. Ob qho tib si muaj qhov zoo thiab qhov tsis zoo, thiab kev sib ntaus sib tua rau qhov chaw sab saum toj hauv kev ua lag luam phab ntsa.
Thaum nws los txog rau tus LED thiab LCD video kev sib cav tswv yim, nws tuaj yeem nyuaj rau kev xaiv ib sab. Los ntawm qhov sib txawv hauv technology rau daim duab zoo.Qhov ntau yam uas koj yuav tsum xav txog qhov kev daws teeb meem twg yog qhov haum rau koj cov kev xav tau.
Nrog rau lub ntiaj teb video kev ua lag luam teeb tsa los ntawm 11% los ntawm 2026, yeej tsis tau muaj lub sijhawm zoo dua tau txais mus rau grips nrog cov lus no.
Koj yuav xaiv cov zaub nrog tag nrho cov ntaub ntawv no los txiav txim siab ho?
Qhov txawv yog dab tsi?
Txhawm rau pib nrog, txhua qhov coj tawm tsuas yog LCDs xwb. Ob leeg siv cov kua siv lead ua kua (LCD) thev naus laus zis tso rau sab nraum qab ntawm lub vijtsam kom tsim cov duab peb pom ntawm peb cov ntxaij vab tshaus. LED Screens Siv lub teeb pom kev zoo rau cov Backlights, Thaum LCDs siv cov bluorescent backlights.
LEDs kuj tseem tuaj yeem muaj tag nrho cov teeb pom kev zoo tag nrho. Nov yog qhov uas LEDs tau muab tusyees hla lub vijtsam tag nrho, hauv txoj kev zoo sib xws rau LCD. Txawm li cas los xij, qhov sib txawv tseem ceeb yog tias cov LEDs tau teeb tsa ib cheeb tsam thiab cov chaw no tuaj yeem ua tau ntev. Qhov no yog lub npe hu ua lub zos dimming thiab tuaj yeem txhim kho daim duab zoo. Yog hais tias ib feem ntawm qhov screen xav tau tsaus ntuj, thaj tsam ntawm LEDs tuaj yeem tsim kev nyab xeeb los tsim cov xim dub thiab kev txhim kho cov duab sib txawv. LCD cov ntxaij tsis muaj peev xwm ua qhov no raws li lawv tau tas li ntawm lub taub hau.
LCD video phab ntsa hauv thaj chaw tos txais
Daim duab zoo
Cov duab zoo yog ib qho ntawm cov teeb meem kev nkag siab tshaj plaws thaum nws los txog ntawm LED thiab LCD video sib cav tswv yim. LED cov lus qhia feem ntau muaj daim duab zoo dua piv rau lawv LCD counterparts. Los ntawm cov qib dub los sib piv thiab tseem xim yog qhov tseeb, coj cov ntsiab lus feem ntau tawm ntawm sab saum toj. Cov ntxaij vab tshaus LED nrog tag nrho-array tom qab-lit cov zaub muaj peev xwm ntawm lub zos Dimming yuav muab cov duab zoo tshaj plaws.
Hais txog kev saib lub kaum sab xis, feem ntau tsis muaj qhov sib txawv ntawm LCD thiab LED video phab ntsa. Qhov no hloov nyob ntawm qhov zoo ntawm lub iav vaj huam sib luag siv.
Cov lus nug ntawm kev saib deb yuav cog qoob loo hauv LED thiab cov kev sib tham. Nyob rau hauv dav dav, muaj tsis yog qhov kev ncua deb ntawm ob lub thev naus laus zis. Yog tias cov neeg saib yuav tau saib kom ze ntawm cov vijtsam xav tau lub siab pixel siab tsis hais seb koj daim vis dis aus siv lossis LCD thev naus laus zis.
Qhov loj
Qhov twg cov zaub yuav tau muab tso thiab qhov loj me yog qhov tseem ceeb hauv lub vijtsam uas yog rau koj.
LCD Video Phab Ntsa Feem ntau tsis ua kom loj li LED phab ntsa. Nyob ntawm qhov kev xav tau, lawv tuaj yeem teeb tsa sib txawv tab sis yuav tsis mus rau qhov ntau thiab tsawg LED phab ntsa tau. LEDs tuaj yeem loj npaum li koj xav tau, ib qho loj tshaj plaws yog nyob hauv Beijing, uas ntsuas 25 mx 30 m (820 ft) rau tag nrho thaj tsam ntawm 7,500 m² (80,729 ft²). Cov zaub no yog ua los ntawm tsib lub vijtsam loj loj los tsim ib daim duab txuas ntxiv.
Ci ntsa iab
Qhov chaw koj yuav muab tso tawm koj daim video phab ntsa yuav qhia koj txog qhov ci ntsa iab uas koj xav tau cov ntxaij vab tshaus.
Ntau dua qhov ci yuav xav tau nyob rau hauv ib chav nrog cov qhov rais loj thiab ntau lub teeb. Txawm li cas los xij, nyob rau hauv ntau cov chav tswj tau qaim yog qaim yuav yuav tsis zoo. Yog tias koj cov neeg ua haujlwm tau ua haujlwm ib puag ncig nws ntev lawv yuav raug kev txom nyem los ntawm mob taub hau lossis qhov muag. Nyob rau hauv cov xwm txheej no, LCD yuav yog qhov kev xaiv zoo dua li tsis muaj kev xav tau ntawm qib siab dua.
Txawv txav
Sib piv kuj tseem yog ib yam dab tsi los xav txog. Qhov no yog qhov sib txawv ntawm qhov screen lub ci ci thiab tsaus xim. Cov kev sib piv sib piv rau LCD cov lus qhia yog 1500: 1, thaum LEDs tuaj yeem ua tiav 5000: 1. Tag nrho-array backlit LEDs tuaj yeem muab lub teeb ci siab vim yog cov backlighting tab sis kuj yog ib tug truer dub nrog lub zos dimming.
Cov coj cov chaw tsim khoom lag luam tau tibneeg hu tauj coob nthuav lawv cov khoom lag luam los ntawm kev tsim qauv tshiab thiab thev naus laus zis. Raws li qhov tshwm sim, cov zaub ua tau zoo tau txhim kho kom tau zoo heev, nrog cov ntxaij vab tshaus ultra siab (UHD) cov ntxaij vab tshaus thiab 8K daws teeb meem ua tus qauv tshiab hauv video phab ntsa thev naus laus zis. Cov kev nce qib no tsim ib qho kev pom zoo dua rau cov neeg saib xyuas.
Hauv kev xaiv, qhov kev xaiv ntawm LED thiab LCD video ntsa chant Technologies nyob ntawm tus neeg siv daim ntawv thov thiab nyiam tus kheej. LED Tshuab yog qhov zoo tshaj plaws rau kev tshaj tawm sab nraud thiab kev pom kev loj heev, thaum lub sijhawm LCD zoo dua rau cov duab hauv tsev uas yuav tsum muaj cov qauv kev daws teeb meem siab. Raws li ob thev naus laus zis txuas ntxiv txhim kho, cov neeg siv khoom tuaj yeem cia siab tias tseem muaj cov duab pom zoo dua thiab muaj xim tob dua los ntawm lawv cov phab ntsa video.
