Lub me me-pitch LED pob tshab npo yog ib yam khoom tshiab uas tau txhim kho nws cov kev daws teeb meem ntawm cov tsoos LED lub npe-tshuaj ntsuam xyuas.Yog li dab tsi ntawm qhov sib txawv peb tuaj yeem hais raws li lub vijtsam me me?Thaum LED taw tes sib nrug ntawm qhov me me-pitch pob tshab npo yog qis dua P2.5, peb tuaj yeem hais tias qhov me me-pitch LED yog pob tshab.Tam sim no, peb qhov teeb meem loj hauv qab no hauv daim ntawv thov me me-pitch LED pob tshab cov ntxaij vab tshaus ntawm kev ua lag luam yuav tsum tau txhim kho:
1. Qhov nce ntawm cov pixels tuag tshwm sim los ntawm kev txhim kho cov duab zoo
Lub me me-pitch LED pob tshab npo yog tsim los ntawm ntau lub teeb ci LED hlaws, thiab kev faib tawm yog ntom.Ntau tus naj npawb ntawm LED teeb hlaws hlaws hauv ib cheeb tsam, qhov siab dua qhov zoo ntawm lub vijtsam pob tshab, thiab ntau dua cov duab ntawm cov ntsiab lus.Txawm li cas los xij, vim muaj kev tsis xws luag, me me-pitch pob tshab cov ntxaij vab tshaus yog nquag mus rau qhov chaw tuag ntawm lub teeb hlaws.Feem ntau, tus qauv ntawm LED zaub tuag lub teeb tus nqi yog tswj tsis pub dhau 3/10,000, tab sis rau me me-pitch LED pob tshab cov ntxaij vab tshaus, qhov kev tuag ntawm 3/10,000 yog txwv.Lub teeb tus nqi tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev siv txhua hnub.Siv lub P2 me me-pitch LED pob tshab npo ua piv txwv, muaj 250,000 teeb hlaws ib square meter.Piv txwv tias thaj tsam ntawm qhov screen yog 4 square metres, tus naj npawb ntawm cov teeb tuag yuav yog 25 * 3 * 4 = 300, uas yuav ua rau pom kev tsis zoo rau lub vijtsam ib txwm muaj.
Kev daws: Lub teeb tuag feem ntau yog vim li cas rau qhov tsis muaj zog vuam ntawm lub teeb hlaws.Ntawm ib sab, cov cuab yeej tsim khoom ntawm LED pob tshab npo chaw tsim khoom tsis yog raws li tus qauv, thiab muaj teeb meem nrog kev tshuaj xyuas zoo.Ntawm chav kawm, qhov teeb meem ntawm lub teeb hlaws dai tsis raug txiav tawm.Yog li ntawd, cov tuam txhab tsim khoom yuav tsum tswj hwm qhov zoo ntawm cov khoom siv raw raws li cov txheej txheem kev tshuaj xyuas zoo, thiab tib lub sijhawm saib xyuas cov txheej txheem tsim khoom hauv qhov chaw.Ua ntej tawm hauv lub Hoobkas, nws tseem yuav tsum ua 72-teev aging test, overhaul thiab xyuas qhov teeb meem lub teeb tuag, thiab xyuas kom meej tias nws yog cov khoom tsim nyog ua ntej xa khoom.
2. Greyscale poob los ntawm kev txo qhov ci
Qhov sib txawv tseem ceeb tshaj plaws ntawm kev siv sab hauv tsev thiab sab nraum zoov yog qhov hloov pauv ntawm lub teeb ambient.Thaum lub vijtsam pob tshab LED los hauv tsev, nws yuav tsum muaj qhov ci ntsa iab, tab sis thaum lub teeb ci ntawm lub vijtsam pob tshab poob qis dua 600cd / ㎡, lub vijtsam pib pom pom pom tseeb greyscale poob.Raws li qhov ci ntsa iab ntxiv zuj zus, qhov greyscale poob kuj nce.ntau thiab hnyav dua.Peb paub tias qhov siab dua ntawm qib grey, cov xim ntau dua qhov pom ntawm lub ntsej muag pob tshab, thiab qhov muag ntau dua thiab tag nrho cov duab.
Kev daws: Lub vijtsam ci ntsa iab yog tsim rau qhov ci ntsa iab thiab tuaj yeem hloov kho tau.Tsis txhob cuam tshuam ntawm ib puag ncig uas ci dhau los lossis tsaus nti kom ntseeg tau tias cov duab zoo ib txwm muaj.Nyob rau tib lub sijhawm, lub vijtsam nrog qib grey siab tau txais yuav, thiab qib grey tam sim no tuaj yeem ncav cuag 16 ntsis.
3. Qhov teeb meem ntawm cua sov los ntawm kev saib ze
Cov kev tshawb fawb tau pom tias nyob rau hauv cov txheej txheem hloov hluav taws xob ntawm LED cov ntxaij vab tshaus, qhov kev hloov pauv hluav taws xob kho qhov muag tsuas yog kwv yees li 20 ~ 30%, uas yog hais, tsuas yog kwv yees li 20 ~ 30% ntawm cov khoom siv hluav taws xob nkag mus rau hauv lub teeb lub zog, thiab qhov seem 70 ~ 80% ntawm lub zog.Tag nrho cov tau noj nyob rau hauv daim ntawv ntawm thermal tawg, yog li ntawd, lub tshav kub ntawm LED zaub yog loj.Qhov me me-pitch LED pob tshab npo uas ua kom muaj cua sov rau lub sijhawm ntev yuav ua rau sab hauv tsev kub nce siab.Rau cov neeg ua haujlwm sab hauv tsev, nyob rau lub sijhawm ntev yuav tsis xis nyob, thiab txawm tias zaum hauv qhov chaw nyob deb, nws nyuaj rau lub sijhawm ntev.Khaws tus cwj pwm zoo hauv qab kub taub hau.
Kev daws: Kev siv cov khoom siv hluav taws xob zoo tshaj plaws tuaj yeem ua kom muaj kev hloov pauv hluav taws xob zoo li qub, yog li txo qhov cuam tshuam ntawm tshav kub.
Yog hais tias peb qhov teeb meem loj ntawm me me-pitch LED pob tshab cov ntxaij vab tshaus raug daws kom raug, nws yuav tsis cuam tshuam rau kev siv ntawm LED pob tshab cov ntxaij vab tshaus.Yog tias koj xav paub ntau ntxiv txog LED pob tshab cov ntxaij vab tshaus, thov tawm lus thiab qhia rau peb
