LCD vs Direct View LED Video Ntsa: Yuav ua li cas koj yuav tsum paub
Yog hais tias koj nyob nraum nyob rau hauv kev ua lag luam rau ib tug visualization system, koj twb zaum pom tias video phab ntsa qhia tuaj nyob rau hauv ib tug bewildering ntau ntawm cov duab, ntau thiab tsawg pab, thiab technologies. Tej zaum koj kuj tau pom hais tias muaj ntau manufacturers siv cov npe txawv rau tib lub yees thiab ua kev tsis sib haum neeg pab leg ntaubntawv hais txog tej uas technology ua qhov zoo tshaj plaws.
To taub, qhov no muaj peev xwm tsim ib tug ntau ntawm tsis meej pem rau buyers. Rau ntau tus neeg, ib tug taw tes ntawm tsis meej pem yog qhov txawv ntawm ob tug nrov zaub hom: "LCD" (tej zaum hu ua "LED-LCD") thiab "LED" (tej zaum hu ua "Direct View LED"). Tab sis tej zaum lawv yuav suab zoo sib xws, LCD thiab Direct View LED yog ob cov zaub technologies nrog lawv cov cim nta thiab cov kev pab. Yog li ntawd, dab tsi yog cov neeg pab? Yuav ua li cas lawv txawv? Yog hais tias koj nyob nraum tawm tsam kom teb cov lus nug, peb nyob ntawm no los pab!
LCD
LCD (kua siv lead ua zaub) yog ib tug ca vaj huam sib luag zaub hom uas tau nrov rau xyoo nyob rau hauv ob lub video phab ntsa thiab cov neeg siv electronics ciaj uas muag. Muaj feem yuav muaj, koj twb siv LCD technology ob peb zaug ib hnub twg - nws yog cov zaub uas siv nyob rau hauv feem ntau smartphones, computer saib, thiab TV cov ntxaij vab tshaus.
LCD panels yog muaj li ntawm ib tug txheej ntawm kua siv lead ua sandwiched ntawm ob daim ntawm polarized iav. Kua siv lead ua yog ib yam khoom uas ntws zoo li ib tug kua tab sis muaj molecules uas yuav taw qhia kom paub zoo li muaju. Thaum ib tug hluav taws xob tam sim no yog thov rau cov kua muaju, cov muaju ceev, uas lub teeb kis tau los ntawm kev mus tsim ib cov duab. Kua muaju tsis tsim lawv tus kheej lub teeb, yog li Backlights cov txheej txheem ntawm qab lub khob ci ntsa iab cov zaub. LEDs (lub teeb-emitting diodes) yog cov feem ntau ntau hom backlight siv niaj hnub no, thiab ib co manufacturers market lawv cov LED-backlit LCDs li "LED-LCD."
LCDs yuav kaj lug, pheej yig, txhim khu kev qha, thiab muab zoo heev kev kawm. LCD yog ib tug tsis tshua muaj high-resolution technology, li ntawd, LCD video phab ntsa yuav tso saib ntawv nyeem, dluab, thiab video nyob rau hauv ntse nthuav dav. Cov zoo ua LCDs ib tug zoo xaiv rau ib tug ntau ntawm video phab ntsa daim ntaub ntawv, los ntawm cov tub rog tswj cov chav rau lub tsev kawm ntawv kev tshawb fawb chaw.
Thaum LCDs yog tiled ua ke los mus tsim ib tug yees duab phab ntsa, bezels (los yog nqaws) yog pom ntawm tus neeg panels. Qhov no yuav pom raws li ib tug disadvantage thaum muab piv LCD rau seamless zaub hom zoo li Direct View LED. Txawm li cas los, manufacturers yog txo bezel-dav nrog txhua tshiab tiam ntawm qhia, yog li ntawd koj mam li paub tias cov bezels rau newer LCDs muaj ntau hnov li cas.
Saib LED ncaj qha
Zoo li LCD, Direct View LED (tej zaum cia li hu ua "LED") yog ib tug ca-vaj huam sib luag zaub hom uas siv ntawm lub teeb-emitting diodes (LEDs). Txawm li cas los, Direct View LED tej hauj lwm txawv heev los ntawm LCD. Nyob rau hauv ib tug Direct View LED zaub, pua pua ntawm me me LEDs yog mounted ncaj qha rau ib tug vaj huam sib luag, thiab tsis muaj kua siv lead ua los yog polarized iav yog siv. Es tsis txhob ua ib tug backlight (xws li lawv ua nyob rau hauv LCD qhia), lub LEDs nyob rau hauv Direct View LED qhia ua dluab lawv tus kheej. Txhua LED yog yeej tseem zoo ib tug me quav qhov muag teev hais tias emits kob lub teeb thaum ib tug voltage yog thov mus rau nws. Pawg ntawm liab, ntsuab, thiab xiav LEDs yog grouped nyob rau hauv vaj huam sib luag, kev tsim cov kev full-xim pixels yuav tsum tau mus ua tus duab.
Direct View LED yog ib zaug ib tug tsawg dua-resolution zaub uas siv mas nyob rau hauv loj heev sab nraum zoov qhia, tab sis txoj kev loj hlob ntawm me me LEDs nyob rau hauv xyoo tsis ntev los tau ua ntau yuav kho tau sai tau. Cov tsis ntev los no kev kho tau Direct View LED ib exciting tshiab kev xaiv rau sab hauv tsev video phab ntsa.
Direct View LED panels tsis muaj bezels, li ntawd, lawv yuav tsum tau tiled ua ke rau daim ib tug kiag li seamless video phab ntsa . LED qhia yog kuj tsis tshua muaj kaj, txhim khu kev qha, lub zog-npaum, thiab muaj qhov zoo tshaj plaws xim raug thiab ua tshiab cov nqi ntawm tej zaub hom muaj hnub no. Cov qualities ua Direct View LED ib qho kev yoj rau cov loj-scale cov signage thiab lwm yam kev siv uas demand high-tej yam visuals.
Txawm tias tus nqi yog yuav tsum tau txo lub xyoo tom ntej, siab dua-resolution LED phab ntsa uas tam sim no ob peb lub sij hawm ntau kim tshaj LCDs, yog li no technology yog tseem tawm ntawm ncav cuag rau feem ntau cov neeg muas zaub. Nyob rau hauv tas li ntawd, txawm lub siab tshaj plaws-kev daws teeb meem LED qhia tseem tsis tau muab cov ultra-high kho tau muaj nyob rau ntawm LCD. Rau siv-tus neeg mob uas yuav tsum tau saib xyuas mus rau lub finest paub meej, LCD qhia tej zaum tseem yuav dua.
Peb cia siab tias peb twb pab los ib co teeb rau qhov sib txawv - thiab ntau cov kev pab cuam - uas LCD thiab Direct View LED video phab ntsa. Thaum kawg, neb ob leeg yeej zoo heev zaub technologies, thiab tsuas yog koj daim ntawv thov kev thiab nyiaj txiag yuav txiav txim qhov zoo tshaj plaws kev xaiv rau koj.
