Thaum lub LED zaub muag, nws yog ib qho inevitable uas yuav muaj tails. Vim tias cov tails no yog cov khoom sib txawv ntawm cov khoom sib txawv, qhov ci ntsa iab yog qhov sib txawv, thiab cov txiaj ntsig pom tsis zoo tom qab sib dhos. Nyob rau lub sijhawm no, cov cuab yeej kho qhov taw qhia-los ntawm-qhov yuav tsum tau siv.
Kev tshem tawm qhov sib txawv. Point-by-point kho yog ib qho cuab yeej siv los txhim kho qhov ci ci sib xws thiab xim fidelity ntawm LED cov ntxaij vab tshaus. Los ntawm kev sau cov ntaub ntawv ntawm txhua pixel ntawm LED zaub, muab kev kho coefficient matrix, thiab tom qab ntawd rov qab mus rau cov zaub. Lub kaw lus tswj kom paub qhov sib txawv tsav ntawm pixels thiab txo qhov sib txawv ntawm qhov ci thiab xim.

Point-by-point kho yog ib qho cuab yeej siv los txhim kho qhov ci ci sib xws thiab xim fidelity ntawm LED cov ntxaij vab tshaus. Los ntawm cov ntaub ntawv sau los ntawm txhua pixel ntawm LED zaub, ib qho kev kho coefficient matrix yog muab, thiab tom qab ntawd rov qab mus rau cov zaub tswj qhov system, kom paub qhov txawv tsav ntawm pixels, txo qhov sib txawv ntawm qhov ci thiab xim. Cov cuab yeej no tso cai rau cov ntaub ntawv sib txawv ntawm cov ntaub ntawv sib txuas ua ke, thiab lub vijtsam tuaj yeem ua kom pom tseeb thiab muag heev, nrog cov xim tseeb thiab ntuj.
1. Raws li daim ntawv thov, qhov kev kho qhov taw qhia taw qhia tau muab faib ua ob hom:
1. Ib lub txee LED ib leeg yog calibrated taw tes los ntawm taw tes, thiab cov calibration yog nqa tawm ntawm cov kab ntau lawm kom ntseeg tau tias txhua lub txee xa los ntawm lub Hoobkas mus txog qib siab ntawm uniformity;
2, point-by-point calibration ntawm lub vijtsam loj ntawm qhov chaw, xaiv qhov chaw pom qhov tsim nyog rau ntawm qhov chaw calibration ntawm LED puv xim loj npo zaub qhov chaw, kom ntseeg tau tias lub vijtsam zaub ua tiav qib siab ntawm qhov sib xws hauv qhov chaw. thaj chaw soj ntsuam;
2. Kev kho qhov taw tes ntawm taw tes yog muab faib ua chromaticity kho thiab kho qhov ci.
1. Kev kho qhov ci ci yog kev kho ntawm LED luminous siv. Tam sim no, vim tsis muaj cov xim zoo daws teeb meem ntawm qee cov cuab yeej ntsuas ntsuas, qhov sib txawv ntawm cov spectrum no tsis tuaj yeem ntsuas qhov tseeb, yog li nws tsuas tuaj yeem ntsuas qhov luminous siv tab sis tsis yog ntsuas qhov sib txawv ntawm chromaticity.
2. Kev kho chromaticity yog hais txog kev kho lub teeb metering cov cuab yeej uas muaj peev xwm daws cov xim muaj zog, uas tuaj yeem ntsuas qhov ci thiab chromaticity ntawm LED.
Yog li ntawd, nws yog ib qho tsim nyog los ntsuas qhov ci thiab chromaticity yog tias cov khoom siv sib txawv ntawm cov iav iav LED nrog tib lub ntsiab wavelength siv. Nws tuaj yeem tsis tsuas yog xyuas kom meej tias qhov ci ntsa iab ntawm tag nrho LED cov khoom siv hluav taws xob hauv lub vijtsam zoo ib yam, tab sis kuj tseem tso saib cov xim xim ntawm lub vijtsam ib txwm. Tus nqi ntawm cov khoom lag luam tail gear feem ntau siab dua li cov khoom loj hauv khw. Los ntawm qhov taw tes-los ntawm-taw tes kho thev naus laus zis, cov khoom sib txawv ntawm tus Tsov tus tw iav tuaj yeem ua haujlwm ib txwm muaj, uas txhim kho kev siv tus nqi ntawm cov khoom siv LED thiab txuag cov neeg siv khoom. Cov nuj nqis loj.
