Kev sib raug zoo ntawm Greyscale thiab Brightness nyob rau hauv Conference Room LED zaub
Greyscale thiab ci ntsa iab yog ob qhov tseem ceeb ntawm lub rooj sib tham hauv chav LED, thiab lawv sib koom ua ke cuam tshuam rau cov duab pom. Greyscale txiav txim siab qhov ntau ntawm qhov ci ntsa iab uas lub pixel tuaj yeem pom, thaum lub teeb ci txiav txim siab qhov kev siv lub teeb ci ntawm lub vijtsam. Ob qhov kev txwv no yog ob qho tib si sib cuam tshuam thiab sib koom ua ke, ua haujlwm ua ke los txiav txim siab qhov ua tau zoo kawg ntawm cov zaub.
I. Grayscale: Lub Pixel's "Expression Library"
Greyscale hais txog qhov ntau ntawm qhov ci ntsa iab uas txhua pixel tuaj yeem pom. Lub siab - greyscale zaub tso cai rau pixels qhia ntau lub teeb ci, los ntawm tag nrho mus rau qhov ci tshaj plaws. Qhov no zoo li tus neeg ua yeeb yam tuaj yeem piav qhia lub ntsej muag ntawm lub ntsej muag, los ntawm frowning mus rau luag; qhov siab dua qhov greyscale, qhov tseeb ntau qhov ntxoov ntxoo, plaub hau, thiab textures hauv daim duab. Thaum ua si qhov kev nthuav qhia PowerPoint hauv chav sib tham, qhov siab - cov zaub grey tuaj yeem nthuav tawm qhov sib txawv ntawm qhov ci ntsa iab hauv cov duab gradient, ua rau cov duab ntxaws dua.
II. Brightness: Qhov screen "Volume"
Brightness yog qhov luminous siv ntawm lub vijtsam zaub, ntsuas hauv nits. Lub ci ci ntawm 300-500 nits yog txaus rau kev siv niaj hnub hauv chav sib tham, tab sis nyob rau hauv qhov chaw ci ntsa iab, xws li chav sib tham nyob ze ntawm lub qhov rais, yuav tsum muaj qhov ci ntsa iab ntau dua los xyuas kom meej tias cov ntsiab lus pom meej. Txawm li cas los xij, qhov ci ci siab dua tsis yog ib txwm zoo dua; Kev ci ntsa iab ntau dhau tuaj yeem ua rau cov ntawv ntug ua rau qhov muag plooj thiab cov keeb kwm dawb ua kom zoo nkauj, cuam tshuam rau kev pom.
III. Qhov sib txawv ntawm Greyscale thiab Brightness
Kev sib raug zoo ntawm greyscale thiab ci ntsa iab zoo li ob tus neeg koom tes ntawm lub saws tes; Thaum ci ntsa iab nce ntxiv, cov qib siab me me ntawm grey-xim av tuaj yeem "diluted." Qhov no yog vim lub teeb ci LED "overwork" ntawm qhov ci ntsa iab, poob lub peev xwm los tswj qhov ci ntsa iab. Hloov pauv, qhov zoo ntawm qhov siab grey nplai kuj tseem npog qhov ci ntsa iab, vim tias lub teeb ci ntsa iab ua rau qhov sib txawv ntawm daim duab tsis muaj zog. Yog li ntawd, cov kws tshaj lij cov tuam txhab siv "kev ci ntsa iab-txoj kev nkhaus" los ntsuas cov zaub, kom ntseeg tau tias qhov kev ua haujlwm grey tseem nyob ruaj khov txawm tias qhov ci hloov pauv.
IV. Tus khub zoo tshaj plaws rau Chav Sib Tham Scenarios
Hauv cov xwm txheej hauv chav sib tham, tus yuam sij rau ntsuas qhov ntsuas grey thiab qhov ci ntsa iab yog xav txog lub teeb pom kev zoo thiab hom ntsiab lus. Ib chav sib tham uas tsaus nti tuaj yeem xaiv qhov ci qis dua thiab siab dua grayscale los nthuav qhia cov duab ntxaws; thaum lub vijtsam sib koom hauv thaj chaw qhib chaw ua haujlwm yuav tsum muaj qhov ci ntsa iab dua, thaum tsim nyog rau kev txi grey nplai raug kom ntseeg tau cov ntsiab lus pom. Tsis tas li ntawd, qib greyscale siab khaws cov ntsiab lus tsaus nti thaum ua yeeb yaj kiab, thaum lub teeb ci siab ua ke nrog cov theem nruab nrab greyscale zoo dua cov ntsiab lus tseem ceeb thaum nthuav tawm cov kab kos duab. Qee qhov siab - kawg qhia txhawb "lub zos dimming," uas ntxiv txhim kho cov duab sib piv thiab nthuav dav.
V. Zam Kev Tsis Txaus Siab: Tsis txhob dag los ntawm kev qhia tshwj xeeb
Thaum xaiv ib qho LED zaub rau chav sib tham, tsis txhob yuam kev los ntawm qhov yooj yim grayscale siab lossis siab brightness specifications. Qee cov tuam txhab lag luam tuaj yeem tshaj tawm "peak brightness," tab sis qhov kev siv tas li yuav ua rau txo qis vim muaj teeb meem kub dissipation; Lwm tus neeg thov "16-ntsis greyscale," tab sis cov kev txhawb nqa tsav tsheb tsuas tsis tuaj yeem ua qhov kev ua haujlwm siab. Yog li ntawd, thaum yuav khoom, nws yog ib qho tsim nyog yuav tau ua qhov kev ntsuam xyuas grayscale kom pom tias cov kev hloov pauv tau du; tib lub sijhawm, siv lub xov tooj ntawm tes los ntsuas qhov ci kom ntseeg tau tias cov zaub ua tau raws li koj xav tau tiag tiag.
Cov ntsiab lus
Greyscale thiab ci ntsa iab yog ob qhov tseem ceeb ntawm LED cov lus qhia rau chav sib tham, thiab lawv sib koom ua ke txiav txim siab qhov zoo ntawm cov khoom siv. Hauv kev siv tswv yim, ob qhov kev ntsuas no yuav tsum tau sib npaug raws li cov xwm txheej xws li lub teeb pom kev zoo thiab cov ntsiab lus kom ua tiav cov txiaj ntsig zoo tshaj plaws. Nyob rau tib lub sijhawm, thaum yuav khoom, nws yuav tsum tau ceev faj ntawm cov tuam txhab kev tshaj tawm cuav thiab txheeb xyuas cov khoom ua tau zoo los ntawm kev sim tiag tiag.
