Paub txog RGB teeb ntawm lubDaim tawv nqaij Analyzer
RGB yog tsim los ntawm lub hauv paus ntsiab lus ntawm cov xim luminescence. Nyob rau hauv layman cov ntsiab lus, nws cov xim sib tov yog zoo li liab, ntsuab, thiab xiav teeb. Thaum lawv lub teeb sib tshooj sib xyaw, cov xim sib xyaw, tab sis qhov ci ntsa iab yog sib npaug ntawm qhov sib npaug ntawm qhov ci ntawm ob, qhov sib xyaw ntau dua qhov ci ntsa iab, uas yog, kev sib xyaw ntxiv.
Rau lub superposition ntawm liab, ntsuab thiab xiav teeb, lub brightest superposition cheeb tsam ntawm lub hauv paus peb xim yog dawb, thiab cov yam ntxwv ntawm additive mixing: qhov ntau superposition, lub brighter.
Txhua ntawm peb cov xim raws, liab, ntsuab, thiab xiav, muab faib ua 256 qib ntawm qhov ci. Ntawm 0, "lub teeb" yog qhov tsis muaj zog tshaj plaws - nws raug tua, thiab ntawm 255, "lub teeb" yog qhov ci tshaj plaws. Thaum qhov peb-xim greyscale qhov tseem ceeb yog tib yam, grey tones nrog txawv grayscale qhov tseem ceeb yog generated, uas yog, thaum peb-xim greyscale yog tag nrho cov 0, nws yog lub darkest dub tone; thaum peb-xim grey nplai yog 255, nws yog lub suab nrov tshaj plaws.
RGB xim yog hu ua cov xim ntxiv vim tias koj tsim dawb los ntawm kev ntxiv R, G, thiab B ua ke (uas yog, tag nrho cov teeb pom kev rov qab rau lub qhov muag). Cov xim ntxiv yog siv rau hauv teeb pom kev zoo, TV thiab computer saib. Piv txwv li, cov duab tsim cov xim los ntawm emitting lub teeb liab, ntsuab, thiab xiav phosphors. Feem ntau ntawm cov pom spectrum tuaj yeem sawv cev raws li kev sib xyaw ntawm liab, ntsuab, thiab xiav (RGB) lub teeb nyob rau hauv ntau qhov sib txawv thiab siv. Thaum cov xim no sib tshooj, xiav, magenta, thiab daj raug tsim.
RGB teeb yog tsim los ntawm peb lub ntsiab xim ua ke los tsim cov duab. Tsis tas li ntawd, tseem muaj xiav LEDs nrog daj phosphors, thiab ultraviolet LEDs nrog RGB phosphors. Feem ntau hais lus, lawv ob leeg muaj lawv cov qauv kev kos duab.
Ob lub teeb dawb LED thiab RGB LED muaj tib lub hom phiaj, thiab ob qho tib si cia siab kom ua tiav cov txiaj ntsig ntawm lub teeb dawb, tab sis ib qho tau nthuav tawm ncaj qha raws li lub teeb dawb, thiab lwm qhov yog tsim los ntawm kev sib xyaw xim liab, ntsuab thiab xiav.
