Ntug LED los yog Direct LED? Direct LED thiab Ntug LED: qhov twg daim duab zoo zoo

Rau hnub tim, LED-backlight rau cov revolutionary advancement nyob rau hauv lub teb ntawm TV ntau lawm nws thiaj li tig mus rau hauv ib tug ntxiv feature, uas yog feem ntau yooj yim xaiv nyob rau hauv dej siab ntawm ib tug los yog lwm ntaus ntawv, raws li nws yog tsim nyog los xav txog cov kev pab cuam ntawm txhua kev xaiv, mus coj ib tug paub kev txiav txim siab.

Tseeb, muas tau ib lub TV, koj tsis xav mus ua ib tug yuam kev nyob rau hauv lub kawg, yuav ib yam dab tsi uas ua tau nruab nrab yog nag hmo lub technology, uas ua rau tsis muaj kev nkag siab rau siv nyob rau hauv hnub no lub neej. Qhov zoo ces, tsis muaj teeb meem loj teeb meem nyob rau hauv cov teeb meem no yog ua tau tsis tau, thiab nws tseem ceeb yog heev exaggerated.

Zoo thiab tsis zoo ntawm cov LED nws tus kheej

Txhua version ntawm LED technology nws muaj nws tus kheej zoo, namely:

• Ib tug kawm ntawv siab ntawm efficiency.
• Lub peev xwm los tsim televisions nrog ib tug ncaj nyias cov ntxaij vab tshaus.
• Lub tiav tsis tuaj kawm ntawv ntawm mercury nyob rau hauv LEDs.

Cov zoo yog xam tau tias yog nyob rau hauv kev sib raug zoo mus rau lwm cov technologies ntawm backlight, uas tau siv yav tas los nyob rau hauv lwm yam TVs.

Nws yog ib nqi sau cia ib tug ob peb tsis zoo, uas yog cov yam ntxwv rau tag nrho cov hom ntawm illumination hom LED:

• Xub thawj, lub backlight ntawm no hom tsis muab paub LCD saib cov ces kaum.
• Finer qauv muaj ib tug sab illumination, tej zaum yuav raug kev txom nyem los ntawm tsis ncaj cov zaub illumination.
• LED-backlight yuav nws thiaj li ntxias undesirable zos dimming duab ntawm qhov screen.

Ntawm cov hoob kawm, xws tsis zoo ib qho kev zoo nyob rau hauv feem ntau tus neeg mob tshem tawm nyob rau hauv ntau yam qauv ntawm televisions thiab saib, raws li cov technology tsis tu ncua pab. Yog li ntawd nws yog tsim nyog los nkag siab kom raug, uas yog tsis yog tus tsuas yog ib qho teeb pom kev zoo muaj feem xyuam rau qhov zoo ntawm daim duab nyob rau TV.

High duab zoo uas tso cai rau kev soj xyuas niaj hnub TVs, yuav tshwm sim lom zem ntau vim lub fact tias cov developers tau pib siv LED backlight technology. Thaum lub sij hawm, lub rov tshwm sim ntawm LED-TVs yuav ua ib tug heev tiag tiag kiv puag ncig nyob rau hauv kev ua lag luam, vim hais tias cov tshiab teeb muab ib tug tseem ceeb kev txhim kho nyob rau hauv cov xim zoo, thiab kuj ho muaj zog lub brightness ntawm daim duab. Txawm li cas los, muaj coob tus neeg nyob ib tug tsim nyog lo lus nug txog seb nws yog ib qho zoo rau xaiv - Ntug LED los yog Direct LED. Tom qab tag nrho, txhua kev xaiv nws muaj nws tus kheej zoo thiab qhov tsis zoo uas yuav tsum raug xam tias yog nyob rau hauv kev xaiv.

Yuav ua li cas yog lawv cov ntsiab sib txawv?

Rau hnub tim, tag nrho cov uas twb muaj lawm loj TV manufacturers siv xwb ob hom illuminations - Ntug LED los yog Direct LED. Ntawm lawv tus kheej, lawv txawv nyob rau hauv tus naj npawb, li zoo raws li nyob rau hauv lub geometrical kev kho ntawm lub LEDs. Nyob ntawm seb yuav ua li cas lub xeem nyob, tej zaum yuav hloov cov yam ntxwv ntawm lub matrix, txhua illumination hom muaj nws tus kheej cov yam ntxwv thiab zoo. Nws yog vim li no, xaiv ib lub TV, nyob rau hauv txhua rooj plaub nws yog tsim nyog los luj tag nrho cov sij hawm thiab muaj kev cuam tshuam rau dab tsi yog tseem zoo dua mus xaiv - Ntug LED los yog Direct LED. Tom ntej no peb saib cov yam ntxwv ntawm txhua kev xaiv.

ntug

Kev siv cov no backlight muab faib rau cov LEDs rau lub sab ntawm lub screen. Yog li ntawd, qhov no technology yog feem ntau xa mus rau raws li sab illumination.

cov kev pab cuam Ntug

Zoo no technology muaj ib tug ob peb:

• Tsis tshua muaj neeg nyias matrix, thiab nyob rau hauv qhov ntsiab lus teb - thiab lub TV nws tus kheej.
• Lub siab kuj brightness.
• Lub taus zoo.

Lub ntsiab kom zoo dua ntawm no technology yog hais tias lub TV yuav nws thiaj li ua hyperfine uas feem ntau tshwm ib tug decisive zoo tshaj nyob rau hauv dej siab ntawm tus xaiv ntawm xws kiag li lawm. Rau hnub tim tau pom ib tug ntshiab sib mus rau hais tias, xaiv ntawm Ntug LED los yog Direct LED, feem ntau muab lawv nyiam mus rau tus thawj embodiment, rau qhov yog vim li cas hais tias niaj hnub manufacturers tsim ultra-nyias kev tshuaj ntsuam nrog xws technology.

Tsis tas li ntawd muaj nqis ntsoov teev yog qhov tseeb hais tias lub sab tis ntawm cov LEDs muab ib tug high degree ntawm lub zog efficiency.

disadvantages Ntug

Tsis tas li ntawd, technology muaj tej yam drawbacks:

• Glare ntawm cov npoo ntawm qhov screen.
• Teeb meem muaj feem xyuam rau lub uniformity ntawm illumination nyob rau hauv tej yam qauv.

Yog hais tias koj ua ib qho kev xaiv nyob rau hauv dej siab ntawm cov Ntug LED, txoj cai yuav tsum tau ceev faj txog qhov tau hais tias tus nqi ntawm cov TV yuav tsum muaj ib tug ob peb ntau, txij li thaum lawv siv tshwj xeeb paab nto yuav tsum tau rau cov tsis tshua muaj teeb tis ntawm cov illumination, raws li zoo raws li tshem tawm tej hnov brightness hloov. Yog hais tias peb tham txog dab tsi yog qhov tsis zoo ntawm no technology, peb yuav tsum tau highlight lub xub ntiag ntawm tej yam flashes ntawm qhov screen npoo, thiab thaum uas ua si, rau Piv txwv li, kaj los daus toj roob hauv pes nyob ze ntawm lub screen npoo ntawm cov daus yuav zog npaum li cas piv nrog rau cov duab nyob rau hauv lub center.

Nyob rau hauv qhov tsaus ntuj nti scenes kuj ntau heev koj yuav tau them nyiaj mloog rau cov nyhuv ntawm ib hom lit, thiab, nyob rau hauv particular, vim lub fact tias LEDs muaj nyob rau ntawm lub perimeter ntawm lub screen, thiab qhov kev ci nyob rau hauv cov cheeb tsam no yog heev zajlus kom. Nws yog ib nqi sau cia qhov tseeb hais tias txawv TVs nyob rau hauv ntau txoj kev qhia yuav taws raws li ib tug tshwm sim ntawm muaj yog ib txwm tau hais tias koj yuav tsum tau nrhiav ib tug ntaus ntawv uas muaj qhov tsawg tshaj plaws tau sib txawv cov duab. Yog hais tias, txawm li cas los, lub TV muaj ib tug feature raws li hauv zos dimming, ces nyob rau hauv cov ntaub ntawv uas koj yuav tsis nco qab zoo rau nws hais tias yog ci ntsa iab, thiab lawv yuav lwj lub mus ob peb vas ntawm tus saib ntawm tej lub sij hawm.

Direct

Backlight hom Direct LED muab rau lub tsev ntawm LEDs tshaj tag nrho cheeb tsam qab lub matrix.

Nyob rau hauv cov ntaub ntawv no, cov neeg kawm ntawv ntawm brightness ntawm tej pab pawg ntawm LEDs yog tsis tshua muaj zoo thiab muaj peev xwm yuav siv tau uas yog sufficiently zos dimming technology, thaum ib tug processor yog teem, li no ua tus zoo npaum li, thiab yog li muab ib tug tsis tshua niaj hnub illumination.

cov kev pab cuam Direct

Xav qhov zoo ntawm Direct LED technology, peb yuav tsum hais cov nram qab no:

• Uniform illumination.
• Txaus siab txog qib uas zoo.
• Qhaj ntawv ntawm npoo ci ntsa iab.
• Ib tug tau theem ntawm brightness.

disadvantages Direct

Tsis tas li ntawd lub Direct LED backlight muaj ib co drawbacks piv rau zoo xws li cov:

• Ntau dua hwj chim noj.
• Tsis xws nyias thickness ntawm lub matrix.
• Loj tawm tswv yim Lag.

Yuav ua li cas los xaiv?

Raws li hais saum toj no, yog tsis muaj leej txhais ntawm kev embodiment yog ntau yam nyob rau hauv ib tug teeb meem no xyov. Nws yog ua tau them sai sai mus rau ib tug xov tooj ntawm cov yam tseem ceeb thaum xaiv ntawm qhov kev xaiv no yog ntau pom, - Direct LED thiab Ntug LED: qhov twg daim duab zoo zoo, qhov twg ntau zog yog consumed, nyob rau hauv lub kawg, cas lub TV muaj ib tug ntau txaus nyiam tsim nyob rau hauv nws tus kheej.

Yog li, yog hais tias tus thickness ntawm tus dais rau koj tsis muaj lub luag hauj lwm, thiab txawm nyob rau hauv cov ntaub ntawv no koj muaj tsis muaj lub tswv yim siv raws li ib tug saib rau ib tug ntau yam ntawm ua si lub computer, nyob rau hauv cov ntaub ntawv no, nws yog heev haum backlight technology Direct, tab sis yog tias koj yog ib tug kiv cua uas tsis tshua muaj nyias pab kiag li lawm, ces tus Ntug - yog qhov zoo tshaj plaws kev xaiv. Nws yog zoo dua rau kev sib piv koj tus kheej mus ua hauj lwm txhua txhua teeb pom kev zoo nyob rau hauv lub khw, li ntawd, koj muaj peev xwm txiav txim siab rau koj tus kheej uas tej kev xaiv yog ntau tau. Raws li rau cov neeg siv ntawm xws TV poob lawm, nws thiaj li teeb pom kev zoo xaiv yog lom zem ntau ib tug teeb meem ntawm txhua tus neeg tsuas saj.
