Ib qho ntawm cov lus nug uas nquag nug txog LED cov ntxaij vab tshaus yog seb lawv puas xav tau lub teeb rov qab. Kev nkag siab txog qhov sib txawv ntawm cov thev naus laus zis thev naus laus zis yog qhov tseem ceeb rau kev teb cov lus nug no, raws li ntau yam ntawm cov ntxaij vab tshaus, xws li LED thiab LCD, ua haujlwm ntawm cov qauv sib txawv. Hauv qhov blog no, peb yuav tshawb txog lub luag haujlwm ntawm kev teeb pom kev zoo hauv ntau yam duab, thiab tshwj xeeb yog tias cov ntxaij vab tshaus LED xav tau nws.
1. Dab tsi yog Backlighting hauv Displays?
Backlighting yog hais txog lub teeb ci siv tom qab lub vaj huam sib luag tso saib kom pom cov duab lossis cov ntsiab lus tau tshwm sim. Feem ntau, qhov teeb pom kev zoo no yog qhov tsim nyog los ua kom pom qhov screen, vim nws muab qhov tsim nyog ci ntsa iab rau cov pixels kom pom cov xim thiab cov duab kom meej.
Piv txwv li, hauv LCD (Liquid Crystal Display) cov ntxaij vab tshaus, cov kua siv lead ua kua lawv tus kheej tsis tawm lub teeb. Hloov chaw, lawv cia siab rau lub teeb rov qab (ib txwm muaj fluorescent, tab sis tam sim no feem ntau LED) kom pom cov pixels tom qab, tso cai rau lawv tso saib duab.
2. Qhov txawv ntawm LED thiab LCD npo
Ua ntej hais txog seb cov ntxaij vab tshaus LED xav tau lub teeb nraub qaum, nws yog qhov tseem ceeb kom paub meej qhov sib txawv ntawm LCD thiab LED cov ntxaij vab tshaus:
Cov ntxaij vab tshaus LCD: LCD thev naus laus zis tso siab rau lub teeb rov qab vim tias cov kua siv lead ua kua siv hauv cov duab no tsis tsim lawv lub teeb. Niaj hnub nimno LCD cov ntxaij vab tshaus feem ntau siv LED backlights, uas ua rau lub sij hawm "LED-LCD" los yog "LED-backlit LCD." Hauv qhov no, "LED" yog hais txog lub teeb ci, tsis yog cov cuab yeej tso saib nws tus kheej.
LED Cov ntxaij vab tshaus (Tseeb LED): Hauv qhov tseeb LED qhia, txhua pixel yog ib tus neeg lub teeb-emitting diode (LED). Qhov no txhais tau hais tias txhua lub LED tsim nws tus kheej lub teeb, thiab tsis tas yuav muaj teeb pom kev zoo. Cov ntxaij vab tshaus no feem ntau pom muaj nyob rau sab nraum zoov, cov ntawv tshaj tawm digital, thiab LED video phab ntsa.
3. Puas LED Cov ntxaij vab tshaus xav tau lub teeb rov qab?
Cov lus teb yooj yim yog tsis yog-qhov tseeb LED cov ntxaij vab tshaus tsis xav tau lub teeb rov qab. Nov yog vim li cas:
Self-Illuminating Pixels: Hauv LED zaub, txhua pixel muaj lub teeb me me-emitting diode uas tsim lub teeb ncaj qha. Txij li txhua pixel tsim nws tus kheej lub teeb, tsis tas yuav muaj lub teeb ci ntxiv tom qab lub vijtsam.
Zoo sib xws thiab sib sib zog nqus dub: Vim hais tias cov ntxaij vab tshaus LED tsis cia siab rau lub backlight, lawv muab qhov zoo sib piv piv thiab tob dub. Hauv LCD zaub nrog backlighting, nws tuaj yeem nyuaj rau kev ua tiav cov xim dub tiag tiag vim tias lub teeb rov qab tsis tuaj yeem raug kaw tag nrho hauv qee qhov chaw. Nrog cov ntxaij vab tshaus LED, ib tus neeg pixels tuaj yeem tua tag nrho, ua rau muaj tseeb dub thiab txhim kho qhov sib txawv.
4. Kev siv ntau yam ntawm cov ntxaij vab tshaus LED
Muaj tseeb LED cov ntxaij vab tshaus feem ntau yog siv nyob rau hauv ntau yam kev ua tau zoo thiab cov ntawv loj loj uas qhov ci, qhov sib piv, thiab cov xim tiag tiag yog qhov tseem ceeb:
Sab nraum zoov LED Billboards: Loj LED cov ntxaij vab tshaus rau kev tshaj tawm thiab digital signage yog nrov vim lawv qhov ci ntsa iab thiab pom, txawm tias nyob hauv tshav ntuj ncaj qha.
Cov Kev Ua Si Arenas thiab Concerts: LED cov ntxaij vab tshaus yog siv dav hauv cov chaw ntau pob thiab cov chaw ua yeeb yam los tso saib cov ntsiab lus dynamic nrog cov xim zoo dua thiab pom kev deb.
Sab Hauv Tsev LED Phab Ntsa: Cov no feem ntau pom hauv chav tswj, tshaj tawm cov studios, thiab cov chaw muag khoom, muab cov lus pom zoo nrog qhov zoo sib xws.
5. Puas muaj cov ntxaij vab tshaus LED uas siv Backlighting?
Technically, qee cov khoom lag luam sau tias "LED cov ntxaij vab tshaus" siv cov teeb pom kev zoo, tab sis cov no yog LED-backlit LCD zaub. Cov ntxaij vab tshaus no siv lub LCD vaj huam sib luag nrog LED backlight tom qab nws los txhim kho qhov ci thiab lub zog ua haujlwm. Txawm li cas los xij, cov no tsis yog qhov tseeb LED zaub.
Nyob rau hauv qhov tseeb LED cov ntxaij vab tshaus, tsis muaj backlight yuav tsum, raws li lub teeb-emitting diodes yog lub hauv paus ntawm ob lub teeb thiab xim.
6. Cov txiaj ntsig ntawm True LED Screens
Qhov tseeb LED cov ntxaij vab tshaus muaj ntau qhov zoo dua li cov thev naus laus zis thev naus laus zis:
Higher Brightness: Txij li txhua pixel emits nws tus kheej lub teeb, LED cov ntxaij vab tshaus tuaj yeem ua tiav qhov ci ntsa iab ntau dua, ua rau lawv zoo tagnrho rau kev siv sab hauv tsev thiab sab nraum zoov.
Txhim kho qhov sib piv: Nrog lub peev xwm los tua ib tus pixels, LED cov ntxaij vab tshaus muab qhov sib piv zoo dua thiab cov xim dub tob dua, txhim kho cov duab zoo.
Zog Efficiency: LED zaub tuaj yeem ua kom muaj zog ntau dua li backlit LCD cov ntxaij vab tshaus, vim lawv tsuas yog siv lub zog qhov xav tau lub teeb, es tsis ua kom pom tag nrho lub vijtsam.
Lub neej ntev: LEDs feem ntau muaj lub neej ntev, feem ntau tshaj 50,000 mus rau 100,000 teev, uas txhais tau hais tias cov ntxaij vab tshaus LED tuaj yeem nyob tau ntau xyoo nrog kev txo qis hauv qhov ci thiab xim ua haujlwm.
Xaus
Hauv cov ntsiab lus, qhov tseeb LED cov ntxaij vab tshaus tsis xav tau lub teeb rov qab. Txhua pixel hauv ib qho screen LED tsim nws tus kheej lub teeb, ua rau cov zaub inherently nws tus kheej-illuminating. Cov thev naus laus zis no muaj ntau qhov zoo, suav nrog qhov sib txawv zoo dua, cov xim dub tob dua, thiab qhov ci dua. Txawm li cas los xij, nws yog ib qho tseem ceeb rau kev sib txawv ntawm qhov tseeb LED cov lus qhia thiab LED-backlit LCDs, vim tias tom kawg xav tau lub teeb rov qab.
Yog tias koj tab tom nrhiav rau cov zaub nrog cov duab zoo, kev ua haujlwm ntev, thiab lub zog ua haujlwm, qhov tseeb LED screen yog qhov kev xaiv zoo tshaj plaws - tsis muaj teeb pom kev zoo!
