Nrog txoj kev loj hlob sai ntawm covLED zaub screenkev lag luam, LED zaub kuj nce nyiam los ntawm cov neeg.Raws li ib tug novice, yuav ua li cas paub qhov zoo ntawm LED zaub?
Brightness
Brightness yog qhov taw qhia tseem ceeb tshaj plaws ntawm LED cov ntxaij vab tshaus, uas txiav txim siab seb lub vijtsam LED puas tuaj yeem tso saib cov duab siab.Qhov siab dua qhov ci, qhov pom tseeb dua cov duab pom ntawm qhov screen.Nyob rau tib qhov kev daws teeb meem, qhov qis dua qhov ci, qhov pom qhov muag pom ntau dua qhov pom ntawm qhov screen.
Qhov ci ntsa iab ntawm LED cov ntxaij vab tshaus feem ntau yog ntsuas los ntawm cov ntsuas hauv qab no:
Hauv ib puag ncig sab hauv tsev, nws yuav tsum ncav cuag 800 cd / ㎡ lossis siab dua;
Hauv qhov chaw sab nraum zoov, nws yuav tsum ncav cuag 4000 cd / ㎡ lossis siab dua;
Nyob rau hauv cov huab cua sib txawv, lub vijtsam LED yuav tsum ua kom pom tseeb txaus thiab tuaj yeem ua haujlwm tsis tu ncua rau ntau tshaj 10 teev;
Thaum tsis muaj cua, LED zaub screen yuav tsum tsis txhob pom qhov ci tsis sib xws.
Xim
Cov xim ntawm LED cov ntxaij vab tshaus feem ntau suav nrog: xim kom muaj nuj nqis, qib greyscale, xim gamut loj, thiab lwm yam. Vim qhov sib txawv ntawm cov xim purity, txhua xim muaj nws tus kheej kom muaj nuj nqis thiab greyscale qib, thiab peb tuaj yeem xaiv cov xim sib txawv raws li qhov xav tau sib txawv.Qib greyscale kuj yog ib qho ntawm cov cim tseem ceeb uas cuam tshuam rau qhov zoo ntawm LED cov ntxaij vab tshaus.Nws sawv cev rau qhov ci ntsa iab thiab qhov tsaus ntuj uas muaj nyob hauv cov xim.Qhov siab dua ntawm qib grey, qhov xim zoo dua, thiab nws yuav hnov zoo dua thaum pom.Feem ntau, LED cov ntxaij vab tshaus tso saib grey nplai qib ntawm 16, uas tuaj yeem siv los txiav txim seb qhov zoo ntawm LED cov ntxaij vab tshaus yog qhov zoo heev.
Luminance uniformity
Lub brightness uniformity ntawm LED cov ntxaij vab tshaus yog hais txog seb qhov ci ntsa iab ntawm cov chav nyob ib sab yog sib xws thaum lub sij hawm puv xim.
Lub brightness uniformity ntawm LED cov ntxaij vab tshaus yog feem ntau txiav txim los ntawm kev soj ntsuam qhov muag pom, uas piv cov brightness qhov tseem ceeb ntawm txhua lub ntsiab lus nyob rau hauv tib chav tsev thaum lub sij hawm tag nrho-xim zaub nrog lub brightness qhov tseem ceeb ntawm txhua lub ntsiab lus nyob rau hauv tib chav tsev thaum lub sij hawm sib txawv puv xim.Cov chav nyob uas tsis zoo lossis tsis pom kev ci tsis zoo feem ntau hu ua "dub me ntsis".Cov software tshwj xeeb kuj tuaj yeem siv los ntsuas qhov ci ci ntawm cov chav sib txawv.Feem ntau, yog tias qhov sib txawv ntawm qhov ci ci ntawm chav nyob ntau dua 10%, nws suav tias yog qhov chaw tsaus.
Vim lub fact tias LED cov ntxaij vab tshaus yog tsim los ntawm ntau chav nyob, lawv brightness uniformity yog feem ntau cuam tshuam los ntawm unevenly faib ntawm brightness ntawm units.Yog li ntawd, tshwj xeeb yuav tsum tau them rau qhov teeb meem no thaum xaiv.
Saib lub kaum sab xis
Visual angle yog hais txog lub kaum sab xis siab tshaj plaws uas koj tuaj yeem pom tag nrho cov ntsiab lus ntawm lub vijtsam los ntawm ob sab ntawm lub vijtsam.Qhov loj ntawm lub kaum sab xis saib ncaj qha txiav txim siab cov neeg tuaj saib ntawm qhov screen, yog li qhov loj dua qhov zoo dua.Lub kaum sab xis pom yuav tsum siab tshaj 150 degrees.Qhov loj ntawm lub kaum sab xis saib yog txiav txim siab los ntawm txoj kev ntim ntawm lub raj tub ntxhais.
Xim luam tawm
Cov xim luam tawm yog hais txog qhov sib txawv ntawm cov xim ntawm LED cov ntxaij vab tshaus nrog cov kev hloov hauv qhov ci.Piv txwv li, LED cov ntxaij vab tshaus tso saib qhov ci ntsa iab hauv qhov tsaus ntuj thiab qhov ci ntsa iab tsawg hauv qhov chaw ci dua.Qhov no yuav tsum tau ua cov xim luam tawm los ua cov xim tso tawm ntawm LED cov ntxaij vab tshaus ze rau cov xim hauv qhov xwm txheej tiag tiag, txhawm rau ua kom muaj xim luam tawm hauv qhov tiag tiag.
Cov saum toj no yog cov kev ceev faj peb yuav tsum tau ua thaum xaiv cov ntxaij vab tshaus LED.Raws li ib tug kws tshaj lij LED zaub screen chaw tsim tshuaj paus, peb muaj kev ntseeg siab thiab muaj peev xwm muab koj cov zoo LED zaub cov ntxaij vab tshaus.Yog li, yog tias koj muaj kev xav tau kev yuav khoom, thov hu rau peb ncaj qha thiab peb yuav teb rau koj sai li sai tau.tos ntsoov yuav ua haujlwm nrog koj!
