Raws li thev naus laus zis hloov zuj zus mus, LED cov lus qhia tau muab lawv tus kheej tso rau hauv ntau yam ntawm peb lub neej txhua hnub. Lawv pom nyob txhua qhov chaw, los ntawm kev tshaj tawm cov ntawv tshaj tawm mus rau TV hauv tsev thiab cov ntxaij vab tshaus loj loj siv hauv chav sib tham, nthuav tawm ntau qhov kev siv dav dav.
Rau cov tib neeg uas tsis yog cov kws tshaj lij hauv kev ua haujlwm, cov lus piav qhia kev cuam tshuam nrog LED cov lus tuaj yeem nyuaj rau kev nkag siab. Tsab ntawv xov xwm no tsom mus rau demystify cov ntsiab lus, muab kev nkag siab los txhim kho koj txoj kev nkag siab thiab kev siv cov cuab yeej LED zaub.
1. Pixel
Nyob rau hauv cov ntsiab lus ntawm LED zaub, txhua tus kheej tswj tau LED lub teeb chav tsev yog hu ua pixel. Lub pixel txoj kab uas hla, denoted li ∮, yog qhov ntsuas thoob plaws txhua pixel, feem ntau qhia nyob rau hauv millimeters.
2. Pixel suab
Feem ntau hu ua dotsuab, lo lus no piav qhia qhov kev ncua deb ntawm qhov chaw ntawm ob lub pixels uas nyob ib sab.
3. Kev daws teeb meem
Qhov kev daws teeb meem ntawm LED zaub qhia txog cov kab thiab kab ntawm pixels nws muaj. Tag nrho pixel suav no txhais cov ntaub ntawv muaj peev xwm ntawm lub vijtsam. Nws tuaj yeem raug cais rau hauv module daws teeb meem, rooj daws teeb meem, thiab kev daws teeb meem tag nrho.
4. Saib lub kaum sab xis
Qhov no yog hais txog lub kaum sab xis tsim ntawm kab perpendicular mus rau lub vijtsam thiab qhov taw tes ntawm qhov ci ntsa iab txo mus rau ib nrab ntawm qhov siab tshaj plaws ci ntsa iab, vim qhov pom lub kaum sab xis hloov horizontally lossis vertically.
5. Saib nrug deb
Qhov no tuaj yeem muab faib ua peb pawg: yam tsawg kawg nkaus, pom zoo, thiab qhov pom qhov siab tshaj plaws.
6. Kev ci ntsa iab
Brightness yog txhais raws li tus nqi ntawm lub teeb emitted nyob rau hauv ib cheeb tsam nyob rau hauv ib qho kev taw qhia. Rausab hauv tsev LED zaub, qhov ci ci ntawm kwv yees li 800-1200 cd / m² yog pom zoo, thaumsab nraum zoov tso saibFeem ntau ntawm 5000-6000 cd / m².
7. Tus nqi tshiab
Tus nqi refresh qhia tias pes tsawg zaus cov zaub refreshes cov duab ib ob, ntsuas hauv Hz (Hertz). Ib siab duarefresh tus nqipab txhawb kom ruaj khov thiab tsis muaj flicker tsis pom kev. High-end LED zaub ntawm kev ua lag luam tuaj yeem ua tiav cov nqi tshiab txog 3840Hz. Nyob rau hauv sib piv, tus qauv zaj duab xis ncej tus nqi yog nyob ib ncig ntawm 24Hz, lub ntsiab lus hais tias ntawm ib tug 3840Hz npo, txhua thav duab ntawm 24Hz zaj duab xis yog refreshed 160 zaug, uas ua rau cov exceptionally du thiab meej pom.
8. Ncej tus nqi
Lo lus no qhia txog tus naj npawb ntawm cov thav duab tso tawm ib pliag hauv ib qho video. Vim lub persistence ntawm tsis pom kev, thaum lubncej tus nqimus txog ib qho chaw pib, qhov sib lawv liag ntawm cov thav duab discrete zoo li tas mus li.
9. Moire Qauv
Tus qauv moire yog ib qho kev cuam tshuam cov qauv uas tuaj yeem tshwm sim thaum qhov ntau zaus ntawm lub sensor lub pixels zoo ib yam li cov kab txaij hauv ib daim duab, uas ua rau muaj kev cuam tshuam wavy.
10. Grey Levels
Grey qib qhia tus naj npawb ntawm tonal gradations uas tuaj yeem pom ntawm qhov tsaus ntuj tshaj plaws thiab ci ntsa iab nyob rau hauv tib theem kev siv. Cov qib grey siab dua tso cai rau cov xim nplua nuj thiab cov ntsiab lus zoo dua hauv cov duab pom.
11. Contrast Ratio
Qhov nopiv ntsuas qhov sib txawv ntawm qhov ci ci ntawm qhov ci tshaj plaws dawb thiab qhov tsaus ntuj tshaj plaws hauv cov duab.
12. Xim kub
Qhov kev ntsuas no piav qhia qhov xim ntawm lub teeb ci. Hauv kev lag luam zaub, xim kub yog categorized rau hauv sov dawb, nruab nrab dawb, thiab txias dawb, nrog nruab nrab dawb teeb ntawm 6500K. Cov nqi siab dua lean ntawm cov tones txias dua, thaum cov nqi qis dua qhia cov suab nrov dua.
13. Kev Tshawb Fawb
Cov txheej txheem scanning yuav muab faib ua static thiab dynamic. Static scanning suav nrog taw tes-rau-taw tes tswj ntawm tus tsav tsheb IC tso zis thiab pixel cov ntsiab lus, thaum lub sij hawm dynamic scan siv kab ke tswj qhov system.
14. SMT thiab SMD
SMTstands rau Surface Mounted Technology, cov txheej txheem dav dav hauv kev sib dhos hluav taws xob.SMDhais txog Surface Mounted Devices.
15. Kev siv hluav taws xob
Feem ntau teev raws li qhov siab tshaj plaws thiab nruab nrab siv hluav taws xob. Kev siv hluav taws xob siab tshaj plaws yog hais txog lub zog kos thaum pom qhov siab tshaj plaws grey, thaum lub zog siv nruab nrab sib txawv raws li cov ntsiab lus video thiab feem ntau kwv yees li ib feem peb ntawm qhov siab tshaj plaws noj.
16. Synchronous thiab Asynchronous Control
Synchronous zaub txhais tau hais tias cov ntsiab lus qhia nyob rau hauvLED screen iavdab tsi tshwm sim ntawm lub computer CRT saib hauv lub sijhawm tiag tiag. Lub kaw lus tswj rau synchronous qhia muaj qhov siab tshaj plaws pixel tswj txwv ntawm 1280 x 1024 pixels. Kev tswj hwm asynchronous, ntawm qhov tod tes, suav nrog lub khoos phis tawj xa cov ntsiab lus kho ua ntej mus rau cov zaub tau txais daim npav, uas tom qab ntawd ua si cov ntsiab lus khaws tseg hauv ntu ntu thiab sijhawm. Qhov siab tshaj plaws tswj kev txwv rau asynchronous systems yog 2048 x 256 pixels rau sab hauv tsev thiab 2048 x 128 pixels rau sab nraum zoov.
Xaus
Hauv tsab xov xwm no, peb tau tshawb nrhiav cov ntsiab lus tseem ceeb tshaj lij ntsig txog LED zaub. Kev nkag siab cov ntsiab lus no tsis yog tsuas yog txhim kho koj txoj kev nkag siab ntawm LED cov lus qhia ua haujlwm li cas thiab lawv cov kev ntsuas kev ua tau zoo tab sis kuj tseem pab ua kom paub cov kev xaiv zoo thaum siv cov tswv yim.
Cailiang yog ib lub koom haum exporter ntawm LED zaub nrog peb tus kheej Hoobkas Hoobkas. Yog tias koj xav kawm ntxiv txog LED zaub, thov tsis txhob yigtiv tauj peb!
