LED Zaub Kev Paub Txog Cov Ntsiab Lus
What are the brightness requirements for the screen based on ambient brightness? General brightness requirements are as follows: (1) Indoor: >800 CD/M2 (2) Semi-indoor: >2000 CD/M2 (3) Outdoor (facing south): >4000 CD/M2 (4) Outdoor (facing north): >8000 CD / M2
Yam dab tsi yuav tsum tau txiav txim siab txog qhov screen cheeb tsam tso cai los ntawm tus neeg siv lub xaib? (1) Kev sib raug zoo ntawm kev pom qhov deb thiab qhov loj ntawm qhov chaw; (2) Pixel loj thiab daws teeb meem; (3) Kev kwv yees cheeb tsam raws li chav tsev loj; (4) Screen mechanical installation thiab txij nkawm chaw; (5) Qhov cuam tshuam ntawm lub vijtsam qaij lub kaum sab xis ntawm qhov deb.
Dab tsi playback cuam tshuam tus neeg siv yuav tsum tau? (1) Cov ntawv nyeem: Nyob ntawm cov ntawv loj thiab cov kev xav tau daws teeb meem; (2) Standard video zaub: 320 × 240 pixel matrix; (3) Digital standard DVD zaub: Ntau dua lossis sib npaug rau 640 × 480 pixel matrix; (4) Tag nrho lub computer video: ntau dua lossis sib npaug rau 800 × 600 pixel matrix;
Dab tsi yog qhov ci ntsa iab rau xim liab, ntsuab, thiab xiav hauv cov xim dawb? Kev koom tes ntawm liab, ntsuab, thiab xiav rau xim dawb yog txawv. Qhov laj thawj tseem ceeb yog tias tib neeg retina pom lub teeb ntawm qhov sib txawv wavelength sib txawv. Raws li kev soj ntsuam xyuas dav dav, cov piv txwv hauv qab no tau muab rau kev siv: Yooj yim liab-ntsuab-xiav qhov sib piv: 3: 6: 1 Cov xim liab -ntsuab- xiav ci piv: 3.0: 5.9: 1.1
Vim li cas thiaj siab -kawg puv- xim zaub siv cov xim ntsuab ntshiab?
Nyob rau hauv qhov tseeb LED zaub ntau lawm, siab -efficiency LED raj uas muaj peev xwm ua tau nplua nuj thiab tiag tiag xim yuav tsum raug xaiv, kom thaj tsam ntawm daim duab peb sab xim nyob rau hauv daim duab chromaticity yog loj npaum li sai tau thiab ze rau tus nplaig -zoo li tus spectral xim nkhaus, kom tau raws li cov kev cai ntawm cov xim nplua nuj thiab txaus brightness. Lub ncov ntawm tus nplaig-zoo li tus nkhaus yog nyob ntawm lub wavelength ntawm 515nm, yog li siab -kawg LED qhia siv ntshiab ntsuab LED raj nrog lub wavelength ze rau 515nm, xws li LED raj nrog wavelengths ntawm 520nm, 525nm, los yog 530nm. Raws li cov kev cai tshwj xeeb rau kev ci ntsa iab thiab pixel ceev, yuav ua li cas los xam qhov ci ntawm ib qho LED?
Cov txheej txheem suav yog raws li hauv qab no: (Nqa ob lub liab, ib qho ntsuab, thiab ib qho xiav LEDs ua piv txwv)
Liab LED brightness: Brightness (CD) / M2 ÷ Tus naj npawb ntawm pixels / M2 × 0.3 ÷ 2
Ntsuab LED brightness: Brightness (CD) / M2 ÷ Tus naj npawb ntawm pixels / M2 × 0.6
Blue LED brightness: Brightness (CD) / M2 ÷ Tus naj npawb ntawm pixels / M2 × 0.1
Piv txwv li: Nrog ib tug pixel ceev ntawm 2500 pixels ib square meter, 2R1G1B configuration, thiab ib tug yuav tsum brightness ntawm 5000 CD / M2 ib square meter, ces:
Liab LED ci ci: 5000 ÷ 2500 × 0.3 ÷ 2=0.3
Ntsuab LED brightness: 5000 ÷ 2500 × 0.6=1.2
Blue LED brightness: 5000 ÷ 2500 × 0.1=0.2
Lub brightness ib pixel yog: 0.3 × 2 + 1.2 + 0.2=2.0 CD
Vim li cas thiaj xaiv DVI zaub interface tus qauv?
(1) DVI graphics card interface yog ib qho screen interface uas ua raws li cov qauv hauv computer thoob ntiaj teb;
(2) Ib qho yooj yim installation yam tsis qhib lub computer rooj;
(3) High video nco thiab muaj zog dynamic duab zaub peev xwm;
(4) Muaj zog hardware thiab software compatibility;
(5) Txhawb tag nrho cov kev khiav hauj lwm systems thiab daim ntawv thov software, muab saj zawg zog thiab yooj yim zaub;
(6) Kev tsim khoom loj, tus nqi qis, thiab kev saib xyuas yooj yim.
