Nyob rau hauv lub ntiaj teb no ntawm kev sib txuas lus pom, yeej ib txwm muaj kev sib cav txog qhov twg technology zoo dua, LED los yog LCD. Ob leeg muaj qhov zoo thiab qhov tsis zoo, thiab kev sib ntaus sib tua rau qhov chaw saum toj kawg nkaus hauv video phab ntsa lag luam txuas ntxiv mus.
Thaum nws los txog rau LED vs LCD video phab ntsa sib cav, nws yuav nyuaj rau xaiv ib sab. Los ntawm qhov sib txawv ntawm cov cuab yeej siv rau cov duab zoo.Nws muaj ob peb yam uas koj yuav tau xav txog thaum xaiv cov tshuaj twg uas haum rau koj cov kev xav tau.
Nrog lub ntiaj teb video phab ntsa lag luam teeb tsa kom loj hlob los ntawm 11% los ntawm 2026, yeej tsis tau muaj lub sijhawm zoo dua los tuav nrog cov lus qhia no.
Yuav ua li cas koj xaiv ib qho zaub nrog tag nrho cov ntaub ntawv no los xav txog ho?
Qhov txawv li cas?
Yuav pib nrog, tag nrho cov zaub LED tsuas yog LCDs xwb. Ob leeg siv Liquid Crystal Display (LCD) thev naus laus zis thiab ntau lub teeb tso rau tom qab ntawm lub vijtsam los tsim cov duab peb pom ntawm peb cov ntxaij vab tshaus. LED cov ntxaij vab tshaus siv lub teeb-emitting diodes rau backlights, thaum LCDs siv fluorescent backlights.
LEDs tseem tuaj yeem muaj teeb pom kev zoo tag nrho. Qhov no yog qhov uas cov LEDs tau muab tso sib npaug ntawm tag nrho lub vijtsam, zoo ib yam li LCD. Txawm li cas los xij, qhov sib txawv tseem ceeb yog tias LEDs tau teeb tsa thaj chaw thiab cov cheeb tsam no tuaj yeem dim. Qhov no yog hu ua lub zos dimming thiab tuaj yeem txhim kho cov duab zoo. Yog tias qee qhov ntawm lub vijtsam yuav tsum tsaus dua, thaj tsam ntawm LEDs tuaj yeem dim los tsim kom muaj qhov tseeb dua dub thiab txhim kho cov duab zoo sib xws. Cov ntxaij vab tshaus LCD tsis tuaj yeem ua qhov no vim tias lawv nyob ib puag ncig lub teeb.

Duab zoo
Cov duab zoo yog ib qho teeb meem loj tshaj plaws thaum nws los txog rau LED vs LCD video phab ntsa sib cav. LED zaub feem ntau muaj cov duab zoo dua piv rau lawv cov LCD counterparts. Los ntawm cov qib dub mus rau qhov sib piv thiab txawm tias qhov tseeb xim, cov lus qhia LED feem ntau tuaj rau saum. LED cov ntxaij vab tshaus nrog cov duab puv puv rov qab teeb muaj peev xwm ntawm lub zos dimming yuav muab cov duab zoo tshaj plaws.
Hais txog lub kaum sab xis saib, feem ntau tsis muaj qhov sib txawv ntawm LCD thiab LED video phab ntsa. Qhov no tsis yog nyob ntawm qhov zoo ntawm lub iav vaj huam sib luag siv.
Cov lus nug ntawm kev saib qhov deb tuaj yeem cog rau hauv LED thiab LCD kev sib tham. Feem ntau, tsis muaj qhov sib nrug loj ntawm ob lub thev naus laus zis. Yog tias cov neeg saib yuav tau saib los ntawm qhov kaw qhov screen xav tau qhov siab pixel ceev tsis hais seb koj lub phab ntsa video siv LED lossis LCD thev naus laus zis.
Loj
Qhov twg cov zaub yuav muab tso rau thiab qhov loj me uas xav tau yog qhov tseem ceeb hauv qhov screen uas yog rau koj.
LCD video phab ntsa feem ntau tsis ua kom loj li LED phab ntsa. Nyob ntawm qhov xav tau, lawv tuaj yeem teeb tsa txawv tab sis yuav tsis mus rau qhov loj loj LED phab ntsa tuaj yeem. LEDs tuaj yeem loj npaum li koj xav tau, ib qho loj tshaj plaws yog nyob rau hauv Beijing, uas ntsuas 250 mx 30 m (820 ft x 98 ft) rau tag nrho thaj tsam ntawm 7,500 m² (80,729 ft²). Cov zaub no yog tsim los ntawm tsib lub vijtsam LED loj heev los tsim ib daim duab txuas ntxiv.
Brightness
Qhov twg koj yuav tso saib koj cov phab ntsa video yuav qhia rau koj ntawm qhov kaj koj xav tau cov ntxaij vab tshaus kom ua.
Kev ci ntsa iab siab dua yuav xav tau hauv chav nrog lub qhov rais loj thiab ntau lub teeb. Txawm li cas los xij, hauv ntau chav tswj tau ci dhau lawm yuav zoo li qhov tsis zoo. Yog tias koj cov neeg ua haujlwm ua haujlwm nyob ib puag ncig nws ntev lawv tuaj yeem raug mob taub hau lossis qhov muag pom. Hauv qhov xwm txheej no, LCD yuav yog qhov kev xaiv zoo dua vim tias tsis tas yuav muaj qhov ci ntsa iab tshwj xeeb.
Zoo sib xws
Kev sib piv kuj yog ib yam uas yuav tsum xav txog. Qhov no yog qhov txawv ntawm qhov screen brightest thiab darkest xim. Qhov sib piv piv rau LCD zaub yog 1500: 1, thaum LEDs tuaj yeem ua tiav 5000: 1. Full-array backlit LEDs tuaj yeem muab qhov ci ntsa iab vim qhov teeb pom kev zoo tab sis kuj muaj qhov tseeb dub nrog lub zos dimming.
Cov tuam txhab ua lag luam ua lag luam tau tsis khoom nthuav lawv cov khoom lag luam los ntawm kev tsim qauv tshiab thiab kev nce qib thev naus laus zis. Raws li qhov tshwm sim, cov duab zoo tau txhim kho zoo heev, nrog Ultra High Definition (UHD) cov ntxaij vab tshaus thiab 8K daws teeb meem los ua tus qauv tshiab hauv video phab ntsa technology. Cov kev nce qib no tsim kom muaj kev pom kev pom ntau dua rau txhua tus neeg saib.
Hauv kev xaus, kev xaiv ntawm LED thiab LCD video phab ntsa yees nyob ntawm tus neeg siv daim ntawv thov thiab tus kheej nyiam. LED thev naus laus zis yog qhov zoo tshaj plaws rau kev tshaj tawm sab nraum zoov thiab pom qhov muag loj, thaum LCD thev naus laus zis zoo dua rau kev teeb tsa sab hauv tsev uas yuav tsum muaj cov duab daws teeb meem siab. Raws li ob lub thev naus laus zis no txuas ntxiv txhim kho, cov neeg siv khoom tuaj yeem cia siab tias qhov pom tau zoo dua thiab cov xim tob dua los ntawm lawv cov phab ntsa video.
