LED Screen Pixel Pitch: Kev Ua Yeeb Yam Precision ntawm Pixels
Nyob rau niaj hnub no kev tsim cov cuab yeej siv hluav taws xob sai sai, LED cov lus qhia tau nthuav dav -los ntawm kev tshaj tawm loj heev ntawm lub nroog skyscrapers mus rau kev npau suav zoo li cov keeb kwm yav dhau ntawm cov theem kev hais kwv txhiaj, thiab cov ntxaij vab tshaus nthuav dav heev hauv cov chav sib tham. Lub cev tseem ceeb tshaj plaws uas txiav txim siab cov txiaj ntsig ntawm cov ntxaij vab tshaus no yog "pixel suab." Nws feem ntau yog qhia raws li "P" ua raws li tus lej (piv txwv li, P2.5), qhia qhov kev ncua deb ntawm qhov chaw nruab nrab ntawm ob lub pixels uas nyob ib sab, ntsuas hauv millimeters. Qhov tsawg dua tus lej, ntau pixels ib cheeb tsam, ua rau cov duab ntxaws dua; conversely, ib tug loj tus naj npawb ua rau ib coarser duab, tab sis yog ntau haum rau saib los ntawm ib tug deb. Lub pixel pitch ntawm LED cov ntxaij vab tshaus tsis yog kho tab sis qhov tseeb spectrum ncua ntawm millimeters mus rau micrometers, npog ntau yam xwm txheej.
Nyob sab hauv tsev LED Cov ntxaij vab tshaus: Txuas ntxiv mus rau Micro-Display nyob sab hauv tsev yuav tsum tau saib ze ze thiab pom tseeb heev, yog li ntawd, pixel pitches feem ntau me dua. Tam sim no, cov khoom lag luam nrog lub pixel suab tsawg dua 2.5 millimeters tau sau ua ke hu ua "me me-pitch LED cov ntxaij vab tshaus" thiab tau dhau los ua cov ntsiab lus tseem ceeb rau sab hauv tsev. Cov qauv muaj xws li P2.5, P2.0, P1.875, P1.56, thiab P1.25. Cov qauv nrog lub pixel loj ntawm P1.25 thiab hauv qab no yog qhov tsis paub meej txawm tias nyob deb ntawm 0.5 meters, ua rau lawv hloov pauv zoo tshaj plaws rau cov phab ntsa LCD video thiab tsim nyog rau cov ntawv thov hauv chav sib tham, cov rooj sib tham, cov chaw saib xyuas, thiab siab - cov khw muag khoom kawg. Txhawm rau ua kom tau raws li qhov xav tau sib txawv, cov tuam txhab tsim khoom kuj tau tsim cov qauv tsis zoo xws li P1.92, P1.83, P1.58, thiab P1.26. Nrog rau kev txhim kho thev naus laus zis, "micro-}pitch" LED cov ntxaij vab tshaus nrog pixel qhov ntau thiab tsawg ntawm P0.9, P0.7, thiab txawm tias P0.4 tau nkag mus rau qib siab -kawg lag luam, ncaj qha sib tw nrog siab- kawg hauv tsev TVs thiab xinesmas saib. Txawm li cas los xij, tus nqi tuaj yeem ua ob npaug rau txhua 0.1 hli txo qhov pixel suab, yog li kev xaiv sab hauv tsev yuav tsum muaj kev lag luam tawm - tawm ntawm pob nyiaj siv thiab cov duab zoo.
Sab nraum zoov LED Cov ntxaij vab tshaus: Kev sib ntaus sib tua ntawm ci ntsa iab thiab nqi ntawm qhov ntev
Cov ntxaij vab tshaus sab nraum zoov ntsib cov teeb meem xws li tshav ntuj ncaj qha, ntev - saib deb, thiab tiv thaiv dej thiab plua plav, thiab lawv cov pixel suab loj dua li cov ntxaij vab tshaus sab hauv. Cov qauv qub pib los ntawm P3, nce mus rau P4, P5, P6, P8, P10, thiab loj dua. P3 txog P6 yog cov kev xaiv tseem ceeb rau sab nraum zoov billboards, chaw ntau pob fencing cov ntxaij vab tshaus, thiab theem backdrops - lub pixelation NW nyuam qhuav pom los ntawm 3-5 meters deb, thaum tus nqi thiab hwj chim noj yog tswj. P8 thiab P10 yog siv rau siab dua -qhov chaw tshaj tawm saum ru tsev lossis cov ntawv loj loj raws txoj kev loj, feem ntau saib ntawm qhov deb tshaj 10 meters. Thaum ntxov dhau-qhov LED chips hauv P16 thiab P20 tam sim no tsis tshua muaj vim lawv cov zaub ntxhib thiab xim tsis zoo sib xws. Nws yog ib qho tsim nyog sau cia tias cov ntxaij vab tshaus sab nraum zoov xav tau qhov ci ntsa iab heev (feem ntau siab dua 5000 nits), thiab qhov muag tsis pom kev nrhiav me me pixel suab tuaj yeem ua rau cov cua sov tsis zoo thiab cov nqi nce siab. Yog li ntawd, kev lag luam adage yog "rau cov lus qhia sab nraum zoov, xaiv loj dua li cov pixel me me."
Irregularly Shaped Screens thiab Transparent Screens: Creative-Triven Customized Pitches
Raws li cov lus qhia tsis txwv rau cov duab plaub, pixel pitch designs tau hloov pauv ntau thiab ntau yam. Cov ntxaij vab tshaus LED tsis sib xws (daim duab peb sab, kheej kheej, nkhaus, cylindrical, thiab lwm yam) feem ntau siv cov qauv hloov pauv lossis tshwj xeeb splicing. Lawv cov pixel suab feem ntau yog tus qauv (piv txwv li, P2.5, P3, P4, P5), tab sis nyob rau hauv cov cheeb tsam uas muaj kev hloov pauv los yog cov npoo ntse, cov pitches me me lossis tsis yog -cov khoom sib faib yuav xav tau los tswj cov duab txuas ntxiv. Cov khoom no feem ntau pom muaj nyob rau hauv cov tsev khaws puav pheej science, kos duab kos duab, thiab cov khw muag khoom lag luam, hais txog qhov pom kev cuam tshuam tsis yog kev daws teeb meem.
Pob tshab LED cov ntxaij vab tshaus ua raws li qhov sib txawv logic. Lawv muaj xws li LED strips thiab ib tug perforated qauv. Pixel pitch feem ntau hais tias "kab rov tav pitch × ntsug pitch," xws li P2.8 × 5.6mm, P3.9 × 7.8mm, P10 × 10mm, thiab lwm yam. Kab rov tav pitch txiav txim siab meej, thaum ntsug suab cuam tshuam rau lub teeb transmittance. Thaum siv cov iav ntaub thaiv phab ntsa, yog tias nws xav tau kom tsis txhob cuam tshuam cov teeb pom kev zoo sab hauv tsev, yuav tsum xaiv cov qauv nrog lub suab ntsug loj dua (piv txwv li, P8 × 12mm) yuav tsum xaiv; Yog tias xav tau ntau dua ntawm kev nthuav dav, lub suab kab rov tav yuav tsum tau txo qis. Qhov no yog ib qho piv txwv ntawm "kev sib haum xeeb."
COB Technology: Revolutionizing Traditional Pitch Limits
Tsoos SMD (Surface Mount Device) txheej txheem solder ib tug neeg LED chips mus rau ib tug PCB board. Pitch yog txwv los ntawm lub cev qhov tseeb ntawm lub nti mounting, ua rau nws nyuaj rau kev ua tiav ib lub suab hauv qab P1.0. COB (Chip on Board) thev naus laus zis, txawm li cas los xij, ncaj qha txuas cov nti liab qab mus rau hauv lub substrate, tshem tawm cov nti casing thiab pins, yooj yim tawg los ntawm millimeter - theem pitch txwv. Tam sim no, cov khoom lag luam loj COB suav nrog COB1.58, COB1.56, COB1.26, COB1.25, thiab ntau dua COB0.97, COB0.92, COB0.79, thiab COB0.62. Cov pitches ultra{12}}cov me me no ua rau cov ntxaij vab tshaus LED kom ua tiav hauv "seamless, siab- sib piv, dav- saib-lub kaum sab xis, thiab cuam tshuam- tiv taus" kev ua tau zoo, ua rau lawv tshwj xeeb tshaj yog haum rau siab - kawg chav sib tham, chaw hais kom ua, thiab virtual photography studios. Txawm li cas los xij, COB raug kev txom nyem los ntawm qhov tsis tshua muaj txiaj ntsig, kho nyuaj, thiab tus nqi siab, thiab tam sim no tseem yog tus kws tshaj lij- daim ntawv thov qib.
Yuav Ua Li Cas Xaiv: Ib Qhov System Engineering Project
Tsis muaj qhov "zoo tshaj plaws" suab, tsuas yog lub suab "tsim" tshaj plaws. Rau cov scenes sab hauv tsev, cov qauv qhia pom "saib nrug (meters) ÷ 2 ≈ pom zoo pixel suab (millimeters)" tuaj yeem ua raws. Piv txwv li, xaiv P1.0 rau saib ntawm 2 meters. Rau cov scenes sab nraum zoov, kev kwv yees ntxhib tuaj yeem ua tau siv "qhov deb (meters) ÷ 10 ≈ suab (millimeters)," nrog P3 rau 10 meters, P5 rau 20 meters, thiab P10 rau 50 meters. Cov peev nyiaj- cov haujlwm tseem ceeb tuaj yeem ua kom lub suab zoo; COB tuaj yeem txiav txim siab yog tias qhov kawg ntawm kev xav tau thiab cov peev nyiaj txaus. Tsis tas li ntawd, nco ntsoov tias cov ntxaij vab tshaus sab hauv tsev yuav tsum tsis txhob siv sab nraum zoov (qhov ci tsis txaus thiab tsis muaj dej tsis muaj dej), thiab cov ntxaij vab tshaus sab hauv tsev yuav ua rau lub suab nrov nrov; rau cov duab tsis xwm yeem lossis pob tshab, ib txwm thov cov qauv ntawm lub cev los ntawm cov chaw tsim khoom; COB cov khoom yuav tsum raug txheeb xyuas kom tau dhau cov dej noo{16}} pov thawj thiab cuam tshuam - cov ntawv pov thawj.
Los ntawm qhov roughness ntawm P20 mus rau qhov kawg refinement ntawm P0.4, evolution ntawm LED npo pixel suab yog qhov tseem ceeb tib neeg txoj kev nrhiav tsis tu ncua ntawm "kev tsim tawm tiag tiag." Txhua millimeter txo qis sawv cev rau kev tsim kho tshiab hauv kev ntim tshuab, tsav tsheb ICs, kev tsim hluav taws xob cua sov, thiab txawm tias calibration algorithms. Thaum koj thaum kawg sawv ntawm lub ntsej muag zoo kawg nkaus COB loj loj screen, qhov koj pom tsis yog kab sib chaws ntawm pixels, tab sis lub teeb nws tus kheej -qhov no yog qhov kawg romance ntawm pixel pitch technology.
