Yuav ua li cas yog LED teeb pom kev zoo? hom teeb pom kev zoo

Producers ntawm TV ntau lawm paub cov neeg siv tsis tu ncua nrog cov tshiab technologies uas txhim kho cov duab zoo ntawm kis tau tus mob. Kev mus rau lub reconciliation ntawm lub TV cov ntxaij vab tshaus thiab LED ntsiab tau ntev mastered rau lub loj tshaj plaws kev tuam txhab uas muag. Tsis ntev los no, ib qhov chaw kev kaj lug thiab mos glow kuj kis tau rau mobile qhia. Soj ntsuam seb ua hauj lwm zoo ntawm xws li ib tug kev txiav txim siab tau thiab cov neeg siv cov tshuaj teeb pom kev zoo raws li nyob rau hauv LEDs, tab sis, ntawm chav kawm, feem ntau txaus nyiam looks Backlight LED-cov ntxaij vab tshaus TVs. Qhov ntau li ntawd vim hais tias nws complements thiab lwm yam high-tech tig siv rau txoj kev loj hlob ntawm cov txheej txheem no.

Lub teeb pom kev zoo ntaus ntawv

Nyob rau hauv cov creation ntawm modules los siv rau backlight LED-arrays yog siv uas tej zaum yuav muaj xws li dawb LED ntsiab sib txawv xim los yog luminescence, xws li RGB. Lub Rooj Tswjhwm Saib yog tsim kom equip lub matrix uas tsim los integrate mus rau hauv lub ntaus ntawv cab kuj tej qauv. Feem ntau, rau sab laug ntawm lub Rooj Tswjhwm Saib connectors cov txheej txheem, yog ib tus uas muab ib lub hwj chim LED illumination, thaum lwm tus neeg yog tsim los tswj nws khiav hauj lwm configuration. Tsis tas li ntawd rau LED modules siv ib tug tshwj xeeb tsav tsheb, cov nuj nqi uas yog txuam nrog rau cov xws li.

Nyob rau hauv tas daim ntawv LED sawb muaj ib tug series ntawm tej yam me me teeb uas yog kev cob cog rua rau hauv pab pawg ntawm 3 daim. Yeej, manufacturers tsis pom zoo cuam tshuam nrog lub ntaus ntawv xws tapes, tab sis tej zaum yuav lub cev zog los yog, conversely, ua ntev ntaus ntawv yog kev kawm. Tsis tas li ntawd, lub tsev LED-backlight screen muab lub peev xwm yuav tau kho cov brightness, koom tes du pib thiab yog txawm peem rau nrog tiv thaiv tawm tsam voltage.

Classification backlight chaw hom

Muaj ob txoj kev mus rau integrate LED illumination - ncaj qha thiab qhov xaus. Tus thawj configuration yuav tsum tau hais tias tus array yuav tsum tau nyob qab lub kua siv lead ua vaj huam sib luag. Qhov thib ob xaiv tso cai rau koj los mus tsim heev nyias panels cov ntxaij vab tshaus thiab yog hu ua Ntug-LED. Nyob rau hauv cov ntaub ntawv no, qhov kev tso kawm ntawm daim kab xev ib ncig ntawm lub perimeter ntawm lub sab hauv sab ntawm cov zaub. Yog li ib tug teeb tis ntawm cov LEDs yog nqa tawm los ntawm txhais tau tias ntawm ib tug vaj huam sib luag uas yog pov tseg tom qab lub LCD - feem ntau hom backlight LED-screen yog siv nyob rau hauv txoj kev loj hlob ntawm mobile pab kiag li lawm. Adherents direct backlight qhia zoo tshwm sim ntawm luminescence, uas yog tiav los ntawm ib tug ntau dua tus naj npawb ntawm LEDs raws li hauv zos dimming los txo xim streaks.

Daim ntawv thov ntawm tus LED illuminator

Qhov nruab nrab neeg yuav nrhiav tau qhov no technology nyob rau hauv tus qauv ntawm Sony TVs, LG thiab Samsung, raws li zoo raws li Kodak khoom thiab Nokia. Ntawm cov hoob kawm, tus LEDs tau ua ntau, tab sis nws yog nyob rau hauv tus qauv ntawm cov manufacturers muaj cai zoo hloov nyob rau hauv cov kev taw qhia ntawm kev txhim kho cov neeg zoo ntawm qhov kev txiav txim. Ib tug ntawm cov ntsiab teeb meem uas nyuaj siab los ntawm designers yog los pab txhawb cov kev tshuaj ntsuam kev kawm uas muaj zoo yam ntxwv nyob rau hauv cov nqe lus ntawm ncaj qha tshav ntuj. Tsis tas li ntawd, cov LED LED-backlight twb nyuam qhuav tuaj nyob rau hauv cov nqe lus ntawm ua tus zoo. Yog hais tias peb tham txog cov kev kawm tau nyob rau hauv cov kev taw qhia ntawm qhov kev tshuaj ntsuam qauv, ces muaj teeb meem loj tawm txiav nyob rau hauv lub thickness ntawm lub panels, raws li zoo raws li compatibility nrog ib tug dav screen. Tab sis nyob twj ywm unsolved teeb meem. LEDs yog tsis muaj peev xwm siab tsim lawv muaj peev xwm nyob rau hauv tus txheej txheem ntawm displaying cov lus qhia. Txawm li cas los, qhov no tiv thaiv tsis tau LED-technology displace CCFL-teeb thiab lwv nrog tus tshiab tiam ntawm ntshav cov ntxaij vab tshaus.

nyem nyhuv

Modules raws li nyob rau hauv lub teeb-emitting diodes muaj ib tug ntau ntawm lub peev xwm los muab sib txawv los. Rau ntawm no theem ntawm kev loj hlob ntawm technology manufacturers koom siv ob Stereoscopic daws teeb meem. Tus thawj muab ib tug angular sib txawv ntawm cov tawg fluxes nrog kev pab los ntawm lub diffraction nyhuv. Tus neeg siv yuav perceive rau cov nyhuv hauv lub chav kawm ntawm saib siv tsom iav los yog tsis muaj lawv, uas yog, nyob rau hauv holography hom. Qhov thib ob nyhuv muaj xws li cov xaav ntawm lub luminous flux uas tawm teeb LED-zaub mus rau ib tug predetermined txoj kev nyob rau hauv cov kua siv lead ua khaubncaws sab nraud povtseg. Siv ntawm no technology yuav ua ke nrog 2D thiab 3D-hom tom qab uas tsim nyog hloov dua siab tshiab los yog transcoding. Txawm li cas los, hais txog ib tug ua tau ua ke nrog peb-dimensional cov dluab ntawm lub LED Backlights tsis mus ntseeg nkaws.

Tau tshaj 3D technology

Peb tsis tau hais tias cov kev tshuaj ntsuam nrog LED-backlit, muaj teeb meem loj ntawm kev sis raug zoo nrog cov 3D hom ntawv, tab sis kev pom kev xaav ntawm tus tuav xws li ib tug "daim duab" yuav tsum tau tshwj xeeb tsom iav. Ib qho ntawm feem pheej chaw ntawm no txoj kev loj hlob yog lub tso suab tsom iav. Piv txwv li, engineers nVidia tso ib tug ob peb xyoos dhau los-shutter 3D tsom-iav nrog kua siv lead ua lo ntsiab muag. Rau deflecting teeb beams LED-backlight LCD screen muab rau kev siv ntawm polarization ntxaij lim dej. Nyob rau hauv cov ntaub ntawv no, cov ntsiab lus yog nqa tawm tsis muaj ib tug tshwj xeeb ncej, nyob rau hauv daim ntawv ntawm cov kab xev. Embedded lens muaj ib tug dav array ntawm translucent LED arrays, uas paub cov ntaub ntawv nrog rau cov kev tswj ntaus ntawv.

zoo ntawm tus backlight

Piv rau lwm yam teeb pom kev zoo xaiv, LEDs ho txhim kho qhov zoo ntawm cov neeg TV cov ntxaij vab tshaus. Feem ntau zoo direct duab yam ntxwv - qhov no los tau nyob rau hauv ua tus zoo thiab xim tu tub tu kiv. Qhov siab tshaj plaws zoo xim spectrum ua muab RGB-matrix. Nyob rau hauv tas li ntawd, LED-Backlight txawv uas tsis muaj zog noj. Thiab tiav hluav taws xob noj yuav txo tau ntawm mus txog 40% nyob rau hauv tej rooj plaub. Tsis tas li ntawd muaj nqis ntsoov teev yog tau ua ultrathin cov ntxaij vab tshaus, uas nyob rau tib lub sij hawm muaj ib tug uas tsis muaj ceeb thawj.

shortcomings

Cov neeg tam sim no TVs nrog LED backlight criticized rau lawv cov teeb meem los ntawm kob xiav-violet tawg rau hauv lub qhov muag. Tsis tas li ntawd xiavlus cai nyob rau hauv lub feem ntau "duab" uas distorts lub ntuj xim tu tub tu kiv. Txawm li cas los, nyob rau hauv qhov tseeb versions ntawm TV nrog ib tug high school cov -resolution LED-backlight screen muaj yuav luag tsis muaj zoo li tsis xws luag. Tab sis muaj teeb meem nrog rau cov kev tswj ntawm brightness, nyob rau hauv uas lub muab kev koom tes mem tes dav tes taws los piav. Nyob rau hauv xws chaw, tej zaum koj yuav pom cov kev tshuaj ntsuam flicker.

xaus

Rau hnub tim, lub ya TV qauv nrog LED-technology yog nyob rau hauv nws kiag. Thaum neeg ntsuas lub sij hawm thiab muaj meej mom, uas yog tau muab ib lub tshuaj. Nws yuav tsum tau muab sau tseg tias ua hauj lwm zoo tsis zoo muaj LED LED-teeb, tsis yuam kev neeg siv raws li siab nqi. Muaj ntau cov kws txawj, qhov no zoo tshaj yog suav tias yog ib tug loj teeb meem mus rau lub popularization ntawm technology. Txawm li cas los, lub zeem muag rau LEDs tseem nyob twj ywm pheej, raws li lawv cov nqi yuav txo tau raws li kev thov nce. Parallel rau qhov no thiab lwm yam paub teeb pom kev zoo zoo, uas ntxiv tsub kom lub attractiveness ntawm qhov kev.
