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 lus, nws txoj kev sib xyaw xim zoo li liab, ntsuab, thiab xiav xiav. Thaum lawv cov teeb sib tshooj sib tshooj, cov xim muaj sib xyaw, tab sis qhov ci ci yog sib npaug ntawm ob, ntau dua qhov ci dua qhov zoo dua, uas yog, ntxiv sib xyaw.
Rau cov superposition ntawm liab, ntsuab thiab xiav xiav, qhov ci ci tshaj plaws ntawm nruab nrab peb xim yog dawb, thiab cov yam ntxwv ntawm kev sib xyaw ua ntxiv: lub superposition ntau ntxiv, lub zog dua.
Txhua ntawm peb lub xim raws, liab, ntsuab, thiab xiav, tau muab faib ua 256 qib ci. Ntawm 0, lub teeb "yog qhov tsis muaj zog - nws tau muab tua, thiab ntawm 255, lub teeb" yog qhov ci ntsa iab tshaj plaws. Thaum peb-xim grayscale qhov tseem ceeb yog tib yam, grey suab nrov nrog cov xim sib txawv yog tsim, thaum peb-xim dub muag; Thaum peb-xim grayscale yog 255, nws yog lub suab nrov dawb tshaj plaws.
RGB xim yog hu ua cov xim ntxiv vim tias koj tsim R, G, thiab yog, txhua lub teeb yog xav rov qab rau lub qhov muag). Cov xim ntxiv tau siv hauv teeb pom kev zoo, TV thiab cov tsom iav. Piv txwv li, qhia tawm cov xim tsim xim los ntawm kev teeb pom kev los ntawm liab, ntsuab, thiab phosphors xiav. Feem ntau ntawm cov pom spectrum tuaj yeem sawv cev ua qhov sib xyaw ntawm cov xim liab, ntsuab, thiab xiav (RGB) lub teeb nyob rau hauv sib txawv thiab siv zog. Thaum cov xim sib tshooj sib tshooj, cyan, magenta, thiab daj yog tsim tawm.
RGB teeb tau tsim los ntawm peb thawj xim ua ke los ua ib daim duab. Ib qho ntxiv, tseem muaj xiav leds nrog daj phosphors daj, thiab ultraviolet coj nrog RGB phosphors. Feem ntau hais lus, ob leeg muaj lawv cov ntsiab cai uas xav tau.
Ob lub teeb dawb Led thiab RGB LED muaj tib lub hom phiaj, thiab ob qho tib si kev cia siab kom ua tiav lub teeb dawb, thiab lwm tus yog tsim los ntawm kev sib xyaw liab, ntsuab thiab xiav.
