Qhov zoo ntawm LED zaub screen tuaj yeem txiav txim siab siv rau hauv qab no:
1. Kev ntsuas qhov ci
Siv tau Scenarios: Sab nraum zoov LED zaub yuav tsum tau brightness thiab yuav tsum yoog raws lub teeb muaj zog.
Standard Range: Lub brightness ntawm ib txwm sab nraum zoov tag nrho -xim tshuaj ntsuam yuav tsum mus txog 1200cd/m²-2000cd/m², uas yuav ua tau raws li cov pa chips LED.
Txoj Kev Ntsuas: Siv lub ntsuas luminance los ntsuas qhov ci ntawm qhov nruab nrab thiab plaub fab ntawm lub vijtsam kom ntseeg tau tias muaj kev sib haum xeeb; brightness tsis txaus yuav cuam tshuam rau sab nraum visibility.
2. Kev Ntsuam Xyuas Nyiaj Dawb
Lub hauv paus ntsiab lus: Qhov piv ntawm peb lub ntsiab xim -liab, ntsuab, thiab xiav- yuav tsum yog 1:4.6:0.16 kom tso saib dawb huv. Deviations nyob rau hauv qhov piv no yuav ua rau dawb tshuav distortion.
Txoj Kev Ntsuas: Ua ib daim duab dawb huv thiab saib seb lub vijtsam puas pom cov xim xiav lossis daj -ntsuab ntsuab; Cov khoom lag luam tsis zoo feem ntau ua rau cov xim tsis sib haum vim tsis sib haum xeeb tsav tsheb lossis LED nti tsis.
Qhov tseem ceeb: White balance deviation cuam tshuam rau tag nrho cov xim kev ua tau zoo, tshwj xeeb tshaj yog pom thaum pom lub teeb - cov ntsiab lus xim.
III. Kev kuaj xim luam ntawv
Lus Txhais: Qhov sib xws ntawm cov xim uas tshwm rau ntawm qhov screen thiab cov xim ntawm cov duab hauv lub hauv paus, qhia txog lub peev xwm los tsim cov duab tseeb.
Txoj Kev Xeem: Ua si daim ntawv qhia xim qauv (piv txwv li, daim duab 24-xim lossis 140-xim) thiab sib piv cov xim sib txawv ntawm qhov screen zaub thiab cov duab qub; siv kev colorimetry kom muaj nuj nqis ΔE (ib chav ntawm xim sib txawv). ΔE < 3 yog qhov zoo heev, thaum ΔE > 5 qhia qhov sib txawv xim tseem ceeb.
Daim ntawv thov Scenarios: Kev tshaj tawm, zaj duab xis thiab TV playback, thiab lwm yam kev lag luam uas yuav tsum muaj siab heev rau kev luam xim.
IV. Tuag Pixel Inspection
Lus Txhais: Ib lub pixel uas tsis tu ncua los yog dub tas li, tshwm sim los ntawm kev puas tsuaj LEDs lossis tsis zoo soldering.
Txoj Kev Ntsuas: Ua si lub vijtsam dub ntshiab thiab saib xyuas qhov ci ntsa iab (ntxhiab teeb); Ua si lub vijtsam dawb dawb thiab saib rau qhov tsaus nti (dub tas li); Siv cov kev sim software (xws li, LED Tester) txhawm rau luam theej duab tag nrho lub vijtsam rau cov lej ntawm cov pixels tuag.
Standard: Cov qauv kev lag luam tso cai rau qhov tuag pixel tsawg dua lossis sib npaug li 0.003% (piv txwv li, Tsawg dua lossis sib npaug rau 3 tuag pixels ib square meter). High -cov ntxaij vab tshaus zoo tuaj yeem ua tiav xoom tuag pixels.
V. Xim thaiv teeb meem
Txhais: Cov xim sib txawv tseem ceeb ntawm cov qauv uas nyob ib sab, nrog cov xim hloov pauv tshwm sim ntawm lub module-los ntawm-module hauv paus, tsim kom muaj "mosaic" nyhuv.
Ua rau:
Kev tswj hwm kev ua haujlwm tsis zoo, tsis tuaj yeem tswj hwm qhov greyscale ntawm txhua pixel;
Tsis txaus tshuaj ntsuam greyscale qib (xws li, tsuas yog txhawb 8-ntsis greyscale es tsis txhob 16-ntsis);
Cov xim kub tsis sib haum vim qhov sib txawv ntawm cov khoom sib txawv hauv cov modules.
Txoj Kev Tshawb Nrhiav: Ua si cov duab gradient xim (xws li, xim zaj sawv) thiab saib seb qhov kev hloov ntawm cov modules puas yog ntuj.
VI. Screen Flatness Verification
Standard: Flatness yuav tsum tau tswj nyob rau hauv ± 1mm kom tsis txhob muaj cov duab distortion los yog qhov muag tsis pom qhov muag pom cov ces kaum.
Txoj kev kuaj xyuas:
Siv qib laser los ntsuas qhov tsis sib xws ntawm qhov screen;
Ua tib zoo saib qhov khoob ntawm cov modules; rau me me -pitch screens hauv qab P3, xyuas kom seamless splicing;
Ua si dynamic dluab thiab xyuas cov kab dub los yog lub teeb me ntsis (vim los ntawm lub teeb to ntawm qhov khoob).
Kev cuam tshuam: Kev flatness ntau dhau tuaj yeem ua rau cov duab distortion, tshwj xeeb tshaj yog pom ntawm cov ntxaij vab tshaus lossis cov duab tsis xwm yeem.
Cov lus qhia ntxiv
Kev Ntsuas Kev Ntsuas: Kev ntsuam xyuas dav siv cov txheej txheem tau piav qhia saum toj no yuav tsum tau ua kom tsis txhob muaj xwm txheej uas ib qho qhia tau raws li tus qauv tab sis qhov kev ua tau zoo tag nrho tsis txaus.
Ntev - Lub Sij Hawm Stability: Saib xyuas cov teeb meem xws li qhov ci ntsa iab thiab nce cov LEDs tuag tom qab ua haujlwm tas mus li 72 teev.
Kev Tsim Nyog Muaj Peev Xwm: Ua ntej cov khoom lag luam los ntawm cov chaw tsim khoom uas tau dhau ISO9001, CE, RoHS, thiab lwm yam ntawv pov thawj kom tswj tau qhov zoo.
Kev ntsuam xyuas zoo tuaj yeem paub qhov txawv ntawm qhov siab - zoo thiab qis - cov khoom siv LED zoo, muab cov hauv paus kev tshawb fawb rau kev yuav khoom thiab kev saib xyuas.
