LED cov ntxaij vab tshaus yuav inevitably tsim tails thaum lawv muag. Tail cov khoom yog cov khoom sib txawv ntawm cov khoom sib txawv, nws yog ib qho tsim nyog yuav tsum tsis txhob muaj qhov ci ntsa iab yuav txawv, thiab cov nyhuv tso saib yuav tsis zoo tom qab sib dhos. Nyob rau hauv cov ntaub ntawv no, qhov no technology yuav tsum tau kho los ntawm taw tes.
Kev tshem tawm qhov sib txawv ntawm qhov taw tes yog cov thev naus laus zis los txhim kho qhov sib xws thiab xim fidelity ntawm LED hluav taws xob screen zaub. Los ntawm kev sau cov ntaub ntawv ntawm txhua pixel ntawm LED zaub, ib tug matrix ntawm kev kho coefficients yog muab, uas yog pub rov qab mus rau lub tswj system kom paub qhov txawv ntawm pixels, thiab thaum kawg tsis muaj zog brightness thiab xim txawv taw tes kho yuav txuas nrog rau cov tails. ntawm cov khoom sib txawv, qhov screen zaub yog ntshiab thiab muag heev, thiab xim yog tiag tiag thiab ntuj.
LED zaub
Raws li daim ntawv thov, qhov kev kho qhov taw tes ntawm qhov taw tes tau muab faib ua ob hom.
1. Ib lub thawv LED yog calibrated taw tes los ntawm taw tes, thiab nws yog calibrated lub thawv los ntawm lub thawv thaum lub sij hawm tsim khoom los xyuas kom meej tias txhua lub thawv muaj ib tug uniform qhov siab tom qab ntau lawm.
2. On-site loj-screen calibration point los ntawm taw tes, tag nrho-xim LED loj-screen zaub, xaiv qhov tsim nyog soj ntsuam txoj hauj lwm rau on-site calibration, kom ntseeg tau tias cov zaub qhov siab yog uniform ntawm txoj hauj lwm soj ntsuam.
Kho chroma thiab brightness me ntsis.
1. Kev kho chromaticity yog hais txog kev kho lub teeb pom kev zoo nrog lub peev xwm paub cov xim muaj zog, uas tuaj yeem ntsuas qhov ci thiab chromaticity tus nqi ntawm LED zaub screen.
2. Kev kho qhov ci ci yog kev kho ntawm LED luminous siv. Qee cov khoom siv calibration tsis muaj peev xwm paub cov xim zoo thiab tsis tuaj yeem ntsuas qhov sib txawv spectral kom raug. Lawv tsuas tuaj yeem ntsuas qhov luminous siv, tab sis tsis tuaj yeem ntsuas qhov chromaticity sib txawv.
Thaum siv cov khoom sib txawv ntawm LED cov ntxaij vab tshaus nrog tib lub zog wavelength, qhov ci ntsa iab thiab chromaticity yuav tsum tau kho. Qhov no tsis tsuas yog ua kom ntseeg tau tias tag nrho cov ci ci ntawm LED hluav taws xob cov khoom siv tau zoo ib yam, tab sis kuj tseem muaj cov xim zoo nkauj ntawm cov zaub ib txwm muaj. Cov khoom muag kawg feem ntau muaj cov nqi zoo. Los ntawm kev kho cov thev naus laus zis no me ntsis, tus Tsov tus tw kawg ntawm cov khoom sib txawv no tuaj yeem ua haujlwm ib txwm ua, txhim kho kev siv tus nqi ntawm LED zaub, thiab txuag cov neeg siv khoom cov nqi.
