1. Brightness ntsuas
Nyob rau hauv kev yuav khoom ntawm LED zaub yuav tsum paub meej tias kev siv ntawm scenes ua ntej, yog ntsia rau sab nraum zoov los yog sab hauv tsev, feem ntau, sab nraum zoov teeb, LED zaub brightness yuav tsum tau siab dua, yuav tsum tau ntau tshaj 5000cd / m; thiab lub teeb sab hauv tsev tsis muaj zog, LED zaub qhov ci ci dhau lawm, tab sis ua rau pom kev qaug zog, qhov muag qaug zog thiab lwm yam kev tsis zoo, LED zaub hauv tsev scenes tsuas yog 1800cd / mm tuaj yeem ua tau.
2. White balance indicators
Cov nyhuv dawb tshuav yog ib qho tseem ceeb ntawm cov zaub, lub sij hawm dawb tshuav nyiaj li cas tsis yog tsis paub rau txhua leej txhua tus, tab sis lub hauv paus ntsiab lus tiag tiag, ntau tus neeg tsis paub ntau, tag nrho-xim LED zaub teeb hlaws pob siv peb-hauv-ib pob. , uas yog, lub teeb hlaws hauv qhov tseeb liab, ntsuab thiab xiav peb lub teeb hlaws sib xyaw ua ke, raws li peb lub ntsiab xim sib xyaw ua ke, kom ua tiav cov xim sib txawv, xim science thaum qhov piv ntawm liab, ntsuab thiab xiav thawj xim yog 1 ib: 4.6. 0.16 thaum nws yuav qhia dawb huv, qhov nyiaj tshuav dawb yog txiav txim siab los ntawm kev tswj hwm ntawm cov zaub, lub raj tub ntxhais tseem muaj kev cuam tshuam rau cov xim luam tawm.
3. Grayscale Performance index
Greyscale muaj feem xyuam rau qhov ci ntsa iab, hais txog qhov ci ntsa iab ntawm lub teeb thiab tsaus ntuj ntawm qhov kev nthuav qhia kev ua tau zoo, tseem hu ua xim nplai lossis grey nplai, qhov ntau dua qhov muab qhab nia, LED zaub yog rhiab rau kev nthuav qhia, nws yuav tsum tau siab dua. kev ua tau zoo ntawm LED thiab nti tswj rhiab heev, grayscale grading siab thiab qis feem ntau txiav txim siab qhov vividness ntawm cov xim. Feem ntau hais lus, qhov siab dua ntawm qib grey, cov xim zoo nkauj nthuav tawm los ntawm cov zaub, qhov pom tseeb dua.
4. Flatness Performance index
Flatness yog tag nrho qhov siab ntawm qhov screen undulation, thaum kov lub LED zaub, tsis muaj pob, uas yog hu ua "flatness" nyob rau hauv kev lag luam, txawm hais tias muaj coob tus neeg yooj yim tsis quav ntsej qhov taw tes no thaum yuav, tab sis lub flatness ntawm LED zaub. yog ib qho screen zoo. Feem ntau, qhov me me ntawm qhov flatness, qhov screen zaub yog du, ntau yam xim, qhov zoo dua qhov pom cov nyhuv, qhov opposite yog ib qho yooj yim rau distort daim duab, cov nyhuv tsis zoo.
5. Refresh zaus qhia
Refresh zaus yog hais txog tus naj npawb ntawm lub sij hawm lub vijtsam yog refreshed ib ob, feem ntau, qhov siab dua qhov refresh zaus ntawm LED zaub, qhov ruaj khov thiab du lub vijtsam, thiab qis refresh zaus yuav tsis tsuas muaj dej tsis zoo, kev xav ntawm cov duab ntxoov ntxoo tom qab thiab lagging, tab sis kuj cuam tshuam rau lub qhov muag, pom kev qaug zog, ua rau tib neeg tsis xis nyob. Tshwj xeeb tshaj yog ua si sib tw ua si thiab lwm yam khoom siv LED, kev hloov tshiab zaus yog qhov tseem ceeb, cuam tshuam ncaj qha rau kev paub ntawm kev ua si. Yog li hauv kev xaiv, sim xaiv qhov refresh npaum li cas siab dua 1,000Hz, yog tias qhov refresh zaus siab dua 3,000Hz, nws tuaj yeem raug hu ua qhov ua tau zoo LED zaub, cov nyhuv zoo dua.
