Thaum ntsib teeb pom kev zoo thawj zaug, ntau tus neeg siv khoom nug tib lo lus nug: muaj pes tsawg xim tuaj yeem ua tauRGB teebtsim? Puas yog kaum ob, lossis "ntau lab" feem ntau hais hauv cov khoom lag luam? Cov lus teb muaj ntau yam -xws li nti specifications, txoj kev tsav tsheb, thiab tib neeg pom kev pom- yog li nws tsis tuaj yeem piav qhia tag nrho los ntawm cov kab lus yooj yim "16 lab xim." Cia peb rhuav nws cov kauj ruam - los ntawm - kauj ruam, los ntawm cov hauv paus ntsiab lus mus rau qhov tseeb cov neeg siv.
RGB Xim Mixing Principles: Yuav Ua Li Cas Peb Cov Xim Xim Tsim Ntau txhiab qhov txawv
Hauv plawv ntawm lub teeb RGB yog peb lub teeb ci LED ywj pheej -Liab, Ntsuab, thiab Xiav- uas yog lub npe "RGB" los ntawm. Lub teeb tsis ncaj qha emit xim xws li ntshav, paj yeeb, lossis cyan; Hloov chaw, nws kho qhov ci ntsa iab ntawm txhua lub nti, tso cai rau cov kab teeb ci sib xyaw hauv huab cua thiab "synthesize" cov xim pom los ntawm tib neeg lub qhov muag.
Ntawm no yog ib qho piv txwv yooj yooj yim: yog tias cov channel liab tau teeb tsa rau qhov siab tshaj plaws thaum cov kab ntsuab thiab xiav raug muab tua, qhov tshwm sim yog liab dawb. Yog tias ob qho tib si liab thiab xiav tau teem rau nruab nrab ci thaum ntsuab tawm, qhov tshwm sim yog xim liab. Txoj kev sib xyaw no txawv ntawm cov xim ntawm cov xim uas peb tau kawm txog thaum yau; LEDs cia siab rau kev sib xyaw xim sib xyaw ua ke- txhais tau hais tias thaum tag nrho peb cov xim raug teeb tsa siab tshaj plaws, lawv sib xyaw ua lub teeb dawb es tsis yog xim dub.
Yuav ua li cas cov duab "16.7 lab xim" yog xam
Feem ntau tshaj tawm daim duab ntawm "16.7 lab xim" (tshwj xeeb tshaj yog 16,777,216) tshwm sim los ntawm qhov tseeb tias txhua qhov xim channel txhawb 256 qib ntawm kev hloov ci ntsa iab (xws li ntawm 0 txog 255, sib haum rau 8-ntsis cov ntaub ntawv). Kev suav yog ncaj nraim: 256 (Liab) × 256 (ntsuab) × 256 (Blue)=16,777,216.
Daim duab no sawv cev rau kev sib xyaw ua ke siab tshaj plaws, txiav txim siab los ntawm qhov dimming precision tus tsav tsheb IC muab rau txhua qhov channel. Yog tias ib lub nti txhawb nqa qhov tob me ntsis -xws li 6-ntsis (64 qib)-theoretical tus naj npawb ntawm cov xim poob qis mus txog 260,000. Yog li ntawd, thaum xaiv ib yam khoom los yog sib piv cov specifications, lub ntsiab tseem ceeb yuav tsum tau xav txog yog tus tsav nti lub dimming me ntsis qhov tob, es tsis yog tsuas yog tsom rau cov loj tus naj npawb teev nyob rau hauv lub lag luam cov ntaub ntawv.
Tib neeg lub qhov muag puas tuaj yeem paub qhov txawv ntau xim?
Los ntawm kev pom qhov muag pom, 16.7 lab xim sib xyaw ua ke yeej muaj tiag, tab sis tib neeg lub qhov muag qhov muaj peev xwm sib cais tiag tiag poob qis ntawm qhov loj no. Kev tshawb fawb feem ntau qhia tias tib neeg lub qhov muag noj qab haus huv tuaj yeem paub qhov txawv ntawm ob peb lab xim nyob rau hauv ib txwm teeb pom kev zoo; Txawm li cas los xij, nyob rau hauv ntau qhov chaw uas cov gradients hloov maj mam los yog xim sib txawv me me, ntau qhov sib xyaw ua ke zoo ib yam li qhov muag liab qab.
Qhov no yog vim li cas qee cov tuam txhab lag luam hais tias "ntau lab ntawm cov xim" yog ib qho kev qhia tshwj xeeb thiab kev lag luam. Dab tsi tiag tiag txiav txim siab rau cov neeg siv kev paub yog qhov smoothness ntawm cov xim hloov, qhov tseeb ntawm saturation, thiab seb cov xim distort los yog hloov nyob rau hauv qis brightness theem- cov ntsiab lus uas muaj kev cuam tshuam cov khoom qhov tseeb zoo dua li ib tug tally ntawm tag nrho cov xim.
Peb yam tseem ceeb cuam tshuam rau kev ua haujlwm xim tiag tiag
Tus lej theoretical ntawm cov xim tsuas yog qhov pib taw qhia; Cov hauv qab no yog qhov tseeb txiav txim siab seb lub teeb ua haujlwm li cas hauv tes ntawm tus neeg siv:
Xim sib xws ntawm LED chips:Yog tias muaj qhov sib txawv ntawm cov xim kub lossis lub teeb nyob rau hauv tib lub pob ntawm cov chips, cov qij sib txawv yuav pom cov xim sib txawv txawm tias thaum tau txais cov cim tswj zoo ib yam. Qhov no yog vim li cas cov tuam txhab lag luam loj feem ntau ntiav cov txheej txheem "binning" nruj heev los txheeb cov chips los ntawm xim thiab wavelength.
Tsav IC thiab PWM dimming zaus:Tsawg dhau qhov dimming zaus tuaj yeem ua rau flickering lossis strobing cuam tshuam thaum thaij duab lossis kaw video- tshwm sim uas pom tshwj xeeb tshaj yog nyob rau theem qis. Qhov no yog ib qho tseem ceeb rau kev txiav txim siab thaum ntsuas cov kev daws teeb meem tsav tsheb.
Tswj cov txheej txheem thiab app algorithms:Txawm tias muaj cov khoom siv RGB zoo ib yam, cov xim gamut ntau yam thiab qhov ua kom zoo ntawm cov xim hloov pauv muaj nyob rau hauv ib qho app tus xaiv xim tuaj yeem sib txawv heev. Cov yam no nyob ntawm ntau yam ntawm software- sab algorithm optimization es tsis yog lub teeb kho vajtse nws tus kheej.
Xim sib txawv ntawm RGB thiab RGBW / RGBWW
Txheem RGB qhov muag teev tsim lub teeb dawb los ntawm kev sib tshooj peb xim thawj; qhov tshwm sim "synthetic dawb" lub teeb feem ntau poob qis ntawm cov xim dawb LEDs nyob rau hauv cov nqe lus ntawm Xim Rendering Index (CRI) thiab dawb lub teeb purity. Yog li ntawd, ntau cov khoom lag luam suav nrog lub teeb dawb lub teeb nti nrog rau RGB cov khoom siv - ua rau muaj kev teeb tsa hu ua RGBW (ib leeg dawb channel) lossis RGBWW (dual channels rau sov dawb thiab txias dawb). Qhov kom zoo dua ntawm cov qauv no yog nyob rau hauv nws lub peev xwm los tswj cov xim tib yam - sib xyaw muaj peev xwm raws li tus qauv RGB hauv xim hom, thaum hloov mus rau lub siab dawb siab - lub teeb nti rau dawb - lub teeb hom - ua rau muaj xim zoo dua thiab siv zog ua haujlwm. Rau cov xwm txheej uas xav tau ob qho tib si ambient thiab ua haujlwm (txhua hnub) teeb pom kev zoo, RGBW lossis RGBWW teeb tsa feem ntau muab cov kev daws teeb meem ntau dua.
Qhov yuav tsum tau muaj tiag rau xim suav hla daim ntawv thov
Cov xim ntau dua tsis tas yuav zoo dua rau txhua qhov xwm txheej:
Tsev ambient teeb pom kev zoo:Qhov tseem ceeb yog muab tso rau ntawm cov xim hloov pauv thiab qhov tseeb ntawm cov xim sib xws (xws li sov dawb, sov daj, thiab xiav -violet); ib qho theoretical ntau pua pua txhiab xim feem ntau txaus.
Teeb pom kev lag luam zoo nkauj (theem, tuav, thiab lwm yam):Cov kev xav tau siab yog muab tso rau ntawm cov xim saturation thiab dynamic hloov cuam tshuam; cov kev teeb tsa no ua qhov tseem ceeb ntawm cov xim vibrancy thiab cov lus teb ceev tshaj tus naj npawb ntawm cov nqi xim.
Kev koom ua ke hauv tsev ntse:Qhov tseem ceeb ntawm cov xim suav nyob rau hauv lub nuance ntawm cov xim qhia thaum synchronized nrog suab paj nruag lossis cov ntsiab lus xov xwm; qhov no yuav tsum tau kev ntsuam xyuas nrog rau cov kev sib koom ua ke algorithms.
Cov ntsiab lus
Qhov theoretical siab tshaj plaws ntawm cov xim ib lub teeb RGB tuaj yeem pom yog txiav txim siab los ntawm qhov dimming ntsis -qhov tob ntawm nws cov tsav nti- piv txwv li, tus qauv 8-ntsis system txhawb 16.7 lab xim. Txawm li cas los xij, qhov no tsuas yog ib daim duab lej thiab tsis sib npaug ntawm cov xim sib txawv uas tus neeg siv tuaj yeem pom tau. Qhov tseeb qhov zoo ntawm cov neeg siv kev paub yog nyob ntawm qhov kev ua tau zoo ntawm cov nti sib xws, dimming zaus, thiab tswj algorithms, tsis yog ib daim duab lag luam. Rau cov xwm txheej uas xav tau lub teeb pom kev dawb, RGBW lossis RGBWW cov qauv feem ntau ua tau zoo dua li kev teeb tsa RGB ntshiab.
Yog tias koj tab tom nrhiav ib tus neeg muab kev ntseeg siab ntawm RGB / RGBW ntse qhov muag teev rau koj qhov project lossis hom, lossis xav kho cov xim tsis muaj xim thiab tswj kev daws teeb meem rau cov ntawv thov tshwj xeeb (xws li teeb pom kev zoo hauv tsev, kev lag luam décor, lossis theem teeb pom kev zoo), thov hu rau peb. Peb tuaj yeem muab cov lus qhia tshwj xeeb rau cov khoom lag luam thiab kev txhawb nqa rau cov qauv ntsuas raws li koj qhov kev xav tau tshwj xeeb.
