LED zaub tau dhau los ua ib feem tseem ceeb ntawm ntau lub nroog. LED zaub tuaj yeem pom hauv cheeb tsam kev lag luam, kev sib tshuam, squares thiab lwm qhov chaw hauv ntau lub nroog. Nws ntseeg tau tias ntau thiab ntau tus neeg hauv kev lag luam paub yuav ua li cas txuag hluav taws xob hauv LED zaub. Nws tsis muaj dab tsi ntau tshaj qhov tseem ceeb ntawm LED teeb, tsav ICs, hloov cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tsim, kev siv lub zog txuag hluav taws xob thiab cov qauv tsim hluav taws xob txuag hluav taws xob. kev ua raws li cov qauv no. Nws yog qhov tseeb tias yuav ua li cas thiaj nrhiav tau qhov sib npaug zoo tshaj plaws hauv cov khoom no tuaj yeem ua tiav cov txiaj ntsig zoo tshaj plaws ntawm lub zog txuag ntawm LED zaub. YONGS LED zaub los qhia txog lub zog txuag ntawm LED zaub.
Tam sim no, qhov nrov tshaj 12000cd / m2 high-brightness LED teeb nyob rau hauv Tuam Tshoj yeej siv loj-loj LED chips. Qhov loj-loj LED nti no tau siv dav los ntawm feem ntau LED cov tuam txhab lag luam ua lub hauv paus ntawm kev ua lag luam, thiab tsis muaj cov thev naus laus zis tshiab. Raws li peb txhua tus paub, qhov ci ntsa iab ntawm LED npo yog proportional rau kev tsav tsheb tam sim no ntawm LED teeb. Lub ci ci ntawm 12000cd / m2 tsis muaj dab tsi ntau tshaj li qhov ua kom lub zog tsav tam sim no ntawm LED teeb. Txawm li cas los xij, cov yam ntxwv ntawm lub cev ntawm LED teeb yuav yog qhov kev zam: high-brightness LED teeb yuav tsum tau nrog rau siab attenuation thiab tsis tshua muaj stability yam ntxwv. Lub siab attenuation tsis yog tsuas yog ua rau kev siv mus sij hawm ntev ntawm LED zaub, tab sis kuj dhau los ua qhov tsis xws luag ntawm kev ua kom pom kev ci ntsa iab ntau dhau, thiab qhov teeb meem hauv lub cev yuav ua rau lub neej thiab cov duab ntxim nyiam ntawm LED zaub txhua lub sijhawm. thiab los ntawm cov nyhuv multiplier.
Siv lub high-brightness PH16mm zaub screen ua piv txwv, cov kev tsis tau ntawm no high-brightness LED teeb qhia tau hais tias lub brightness ntawm 12000cd/m2 yuav tsum attenuated tiag rau 8000cd/m2 nyob rau hauv 1.5-2 xyoo, thiab nws txhua xyoo attenuation tus nqi yuav ncav cuag ntau tshaj 20 feem pua. Qee cov tuam txhab lag luam tsis lees paub tias qhov ci ntsa iab tseem yuav ncav cuag ntau dua 10000cd / m2 tom qab 2 xyoos, thiab cov neeg siv khoom yuav lub vijtsam zoo li no, txawm tias qhov txo qis sai heev tom qab 2 xyoos, tab sis daim ntawv cog lus tau ua tiav, thiab tsis muaj kev tsis txaus siab. . qhov rooj. Qhov tseeb, cov neeg siv khoom tuaj yeem siv txoj hauv kev yooj yim los txheeb xyuas, uas yog, kom pom cov txiaj ntsig ntawm ntau lub teeb ci ntsa iab uas tau ua haujlwm ntau dua 2 xyoos thiab siv ntau tshaj 12 teev hauv ib hnub. Qhov loj dua yog tias tom qab qhov ci ntsa iab tau poob los ntawm 12000cd / m2 mus rau 8000cd / m2, nws qhov kev ua haujlwm siab tam sim no tsis tau hloov pauv, thiab qhov ceev ntawm nws qhov ci ntsa iab yuav raug muab faib ua ob npaug, ua rau tom qab attenuation ceev. tso saib. Ntxiv mus, nws muaj nyob rau hauv lub voj voog vicious ntawm brightness attenuation, uas tsis tuaj yeem ua tau raws li cov kev cai ntawm kev siv mus sij hawm ntev.
Txhawm rau kom tsis txhob muaj teeb meem lub teeb thiab ua tau raws li cov cai ntawm kev tiv thaiv ib puag ncig, cov qauv ci ntsa iab ntawm LED cov duab tsis yog tib hnub thiab hmo ntuj. Raws li peb txhua tus paub, txo qhov ci ntsa iab ntau dua lossis tsawg dua poob greyscale, thiab qhov ntau dua qhov kev hloov kho brightness, qhov ntau dua qhov poob ntawm greyscale. Yog li ntawd, yog tias tus nqi pib ci ntsa iab ntawm lub vijtsam LED tau teeb tsa rau 12000cd / m2 thaum nruab hnub, thaum lub teeb ci qis qis rau 800cd / m2 thaum hmo ntuj, txawm tias qhov greyscale poob qis heev, ua rau cov duab zoo thaum hmo ntuj tsis zoo; los yog qhov ci tsis tuaj yeem hloov mus rau hmo ntuj. Kev siv cov txheej txheem kev cai, thiab tsim kom muaj lub teeb hnyav.
