Zoo-pitch LED cov ntxaij vab tshaus feem ntau yog siv hauv kev lag luam, xws li cov chav sib tham ntawm cov tuam txhab, cov thawj tswj hwm lub chaw ua haujlwm, kev sib tham hauv online video, thiab cov ntaub ntawv xav tau hauv cov tsev kawm ntawv thiab cov tsev kawm ntawv. Lawv lub siab ci ntsa iab, tsim seamless, lub teeb yuag thiab hloov tau yooj yim, thiab me me kev teeb tsa hneev taw yog txhua yam zoo nkauj. Txawm li cas los xij, ntau qhov kev tsis sib haum xeeb tseem muaj nyob hauv qhov zoo tam sim no -pitch LED zaub. Yog tias cov kev tsis sib haum xeeb no tsis raug daws kom raug, lawv yuav cuam tshuam rau cov neeg siv kev paub ntawm LED zaub. Cov piv txwv hauv qab no qhia txog qhov no:
1. Txo Brightness thiab Greyscale Poob:
Ib qho ntawm qhov sib txawv tseem ceeb tshaj plaws ntawm kev siv sab hauv tsev thiab sab nraum zoov yog qhov sib txawv ntawm lub teeb pom kev zoo. Thaum cov khoom siv LED siv sab nraum zoov, qhov siv ntawm lub hnub ci thaum nruab hnub yog siab heev, yog li cov lus qhia sab nraum zoov LED yuav tsum ci heev! Qhov tseeb, kom ua tiav cov txiaj ntsig zoo sab nraum zoov, qhov ci ntawm LED zaub yuav tsum ncav cuag 4000 cd / m² (luminous brightness ib chav tsev). Nyob sab hauv tsev, qhov ci ntsa iab ntawm tag nrho - xim LED zaub yuav tsum nyob ib puag ncig 800 cd / m² (candelas ib square meter) kom ntseeg tau tias kev ua haujlwm ib txwm muaj. Txawm li cas los xij, cov kev tshawb fawb tau pom tias qhov ci ntsa iab ntawm 120 cd / m² thiab 150 cd / m² muab kev cuam tshuam zoo ntawm kev noj qab haus huv thiab kev pom. Tsis tas li ntawd, tsis zoo li qhov chaw teeb pom kev tsis zoo, LEDs yog tus kheej - luminous zaub thev naus laus zis, thiab tib neeg lub qhov muag tau nkag siab ntau dua rau cov teeb pom kev ncaj qha, yog li yuav tsum tau qis qis rau kev pom zoo.
Yog li ntawd, thaum LED zaub tau siv nyob rau hauv tsev, lawv qhov ci ntsa iab yuav tsum tau txo kom tsim nyog kom tau raws li cov kev xav tau ntawm sab hauv tsev. Txawm li cas los xij, thaum cov duab ci ntsa iab raug txo mus rau 500 cd / m² lossis txawm tias 600 cd / m² thiab hauv qab no, cov duab pib pom pom qhov poob qis. Nrog rau kev txo qis ntxiv ntawm qhov ci, qhov grey nplai poob yuav hnyav dua (feem ntau, qhov siab dua qib grey, qhov ntau dua cov xim tso rau ntawm qhov screen, thiab cov duab zoo nkauj dua thiab zoo nkauj dua. Grayscale yog qhov txiav txim siab ntawm cov xim uas pom. Thaum qhov ci ntsa iab raug txo qis rau qis dua 200 cd / m², feem ntau cov lus pom muaj kev poob qis, thiab cov duab zoo yuav luag "tsis tuaj yeem," nrog ntau cov ntsiab lus uas ploj lawm . 2. Txhim kho duab Zoo thiab nce Pixel Defects:
Cov duab ntawm ib qho screen LED yog tsim los ntawm suav tsis txheeb me me LED hlaws dai. Yog li ntawd, lub fineness ntawm daim duab zoo yog txiav txim los ntawm lub pixel suab (los yog ceev) ntawm lub teeb hlaws dai. Qhov ntau LED teeb hlaws hlaws rau hauv ib cheeb tsam, qhov siab dua lub ntsiab lus ntawm LED npo, thiab cov zaub ntawm cov duab cov ntsiab lus ntau dua. Raws li qhov no, cov duab LED tam sim no tab tom txhim kho rau me me pixel suab thiab mini-LED cov thev naus laus zis.
Txawm li cas los xij, vim muaj kev txwv tsis pub dhau, LED cov lus pom muaj qhov cuam tshuam rau pixel tsis xws luag. Feem ntau, tus qauv rau cov pixels tuag nyob rau sab nraum zoov LED zaub yog ib txog peb ntawm kaum txhiab. Txawm li cas los xij, rau me me -pitch LEDs, qhov tsis xws luag ntawm peb ib kaum txhiab yuav luag tsis tuaj yeem siv rau txhua hnub. Noj P2.5 me me-pitch LED zaub ua piv txwv, nws muaj 160,000 lub teeb hlaws ib square meter; Yog hais tias lub suab raug txo mus rau 1 millimeter, yuav muaj 1 lab lub teeb hlaws rau ib square meter. Lub sijhawm no, yog tias tus qauv yog "tsis pub ntau tshaj 3 lub pixels tsis zoo," tus lej ntawm cov pixels tsis raug hauv ib qho me me -pitch LED zaub yuav suav tsis tau; thiab ntau qhov screen tsis xws luag yuav ua rau muaj kev tsis txaus siab saib heev.
3. Kaw-Kev Saib Xyuas Ntau Yam thiab Kev Tsim Kho Thaum Muaj Xwm Ceev:
Raws li cov khoom siv sab hauv tsev, tshwj xeeb tshaj yog rau cov khoom lag luam tso rau hauv cov chaw ua haujlwm me me thiab nruab nrab- cov chav sib tham loj, cov neeg saib feem ntau saib thiab siv lub vijtsam nyob ze. Ua ib qho kev sib tham zoo li ib qho piv txwv, lub rooj sib tham tus tswv tsev thiab cov neeg koom nrog kwv yees li 1.5-5 meters deb ntawm qhov screen.
Txawm li cas los xij, qhov luminous efficiency ntawm LED zaub yog tsawg heev. Cov kev tshawb fawb tau pom tias nyob rau hauv cov txheej txheem hloov hluav taws xob ntawm LED cov ntxaij vab tshaus, qhov ua tau zoo ntawm LEDs tsuas yog 100 lm / W, thiab lawv cov electro-kev hloov kho qhov muag tsuas yog li 20-30%. Ntawd yog, 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 yog siv los ntawm cov hluav taws xob hluav taws xob. Nyob rau hauv sib piv, cov teeb incandescent feem ntau siv nyob rau hauv yav dhau los yuav hloov yuav luag tag nrho cov input hluav taws xob lub zog rau hauv lub teeb lub zog hluav taws xob. Yog li ntawd, cov lus qhia LED ua kom muaj cua sov ntau. LED cov ntxaij vab tshaus uas tsim kom muaj cua sov ntau dhau lub sijhawm ntev tuaj yeem nce qhov kub ntawm qhov nruab nrab (txawm tias muaj cua txias thiab lwm yam cua txias, cov cua sov tawm ntawm lub vijtsam thaum lub sijhawm ua haujlwm ntev tuaj yeem ua rau tsis xis nyob). Rau cov neeg tuaj koom lub rooj sib tham, thaum lub rooj sib tham ntev li ib mus rau ob teev lossis ntev dua, cov neeg zaum ze ntawm lub vijtsam uas muaj cua sov hnyav heev yuav muaj kev tsis xis nyob, yuav luag scorching. Txawm tias cov neeg zaum nyob deb yuav pom tias nws nyuaj rau kev tswj hwm tus cwj pwm zoo tom qab ua rau lub sijhawm ntev ntawm cov cua sov, txawm tias lawv tsis tuaj yeem tawm hws zoo li ntsaum ntawm lub phaj kub.
