Cov ntsiab lus hais txog coj zaub

 

 

 

 

 

 

 

1. LED brightness
Lub ci ci ntawm lub teeb-emitting diode feem ntau qhia nyob rau hauv luminous siv, uas yog ntsuas nyob rau hauv candela cd; 1000UCD=1 mcd, 1000mcd=1 cd. Lub teeb siv ntawm ib qho LED rau sab hauv tsev feem ntau yog 500ucd-50 mcd, thaum lub teeb siv ntawm ib qho LED rau sab nraum zoov feem ntau yuav tsum yog 100 mcd-1000 mcd, lossis ntau tshaj 1000 mcd.

 

2. LED pixel module
Cov LEDs yog teem rau hauv matrices los yog cwj mem ntu thiab ua ntej ua rau hauv cov qauv me me. Cov ntxaij vab tshaus sab hauv tsev feem ntau siv yog 8 * 8 pixel modules, 8 cim thiab 7- ntu digital modules. Sab nraum zoov zaub pixel module muaj 4 * 4, 8 * 8, 8 * 16 pixels thiab lwm yam specifications. Lub pixel module rau sab nraum zoov zaub tseem hu ua header bundle module vim hais tias txhua pixel yog tsim los ntawm ntau tshaj li ob LED raj bundles.

 

 

 

3. Pixel thiab pixel txoj kab uas hla
Txhua LED lub teeb-emitting unit (point) uas tuaj yeem tswj tau tus kheej hauv cov duab LED hu ua pixel (lossis pixel). Pixel txoj kab uas hla ∮ hais txog txoj kab uas hla ntawm txhua pixel hauv millimeters.

Rau cov lus qhia sab hauv tsev, feem ntau yog ib qho LED nrog ib lub voj voog. Qhov ntau pixel kab calibration ntawm sab hauv tsev zaub screen yog ∮ 3. .0 yog ntau tshaj.

Nyob rau hauv ib puag ncig sab nraum zoov, txhawm rau txhim kho qhov ci ntsa iab thiab nce qhov pom kev deb, lub pixel muaj ntau tshaj ob pawg LEDs; Txij li ntau tshaj ob pawg LEDs feem ntau tsis yog puag ncig, lub pixel txoj kab uas hla ntawm sab nraum zoov zaub feem ntau qhia los ntawm qhov nruab nrab ntawm ob pixels: P10, P11.5, P16, P22, thiab P25.

 

4. Point nrug, pixel ceev thiab cov ntaub ntawv muaj peev xwm
Qhov nruab nrab ntawm qhov deb lossis qhov chaw ntawm ob lub pixels ntawm LED zaub; Tus naj npawb ntawm pixels ib cheeb tsam yog hu ua pixel ceev; Tus nqi ntawm cov ntsiab lus tso rau hauv ib cheeb tsam yog hu ua cov ntaub ntawv muaj peev xwm. Lub ntsiab lus ntawm peb qhov no yog los piav txog tib lub tswv yim: qhov pixel ceev yog cuam tshuam los ntawm qhov kev ncua deb ntawm ob pixels, thiab qhov sib nrug ntawm pixels thiab pixel ceev yog lub cev lub zog ntawm cov zaub; Cov ntaub ntawv muaj peev xwm yog qhov ntau ntawm cov ntaub ntawv nqa lub peev xwm ntawm pixel ceev.

Qhov me me ntawm qhov sib nrug, qhov siab dua pixel ceev, cov ntaub ntawv muaj peev xwm ntau dua, thiab qhov ze qhov pom qhov deb.
Qhov loj dua qhov sib nrug ntawm qhov sib txawv, qhov qis dua qhov pixel ceev, cov ntaub ntawv muaj peev xwm tsawg, thiab qhov deb nws tsim nyog rau kev saib.

 

 

5. Kev daws teeb meem
Tus naj npawb ntawm kab thiab kab ntawm LED zaub pixels yog hu ua kev daws teeb meem ntawm LED zaub. Kev daws teeb meem yog tag nrho cov pixels hauv ib qho zaub, uas txiav txim siab cov ntaub ntawv muaj peev xwm ntawm cov zaub.

 

6. LED Zaub (LED Vaj Huam Sib Luag)
LED pixel module tau sib sau ua ke thiab npaj rau hauv ib qho matrix raws li qhov loj me ntawm qhov xav tau, thiab tau nruab nrog lub teeb pom kev tshwj xeeb tsav tsheb, DC tswj fais fab mov, software, thav duab thiab kho kom zoo nkauj sab nrauv, thiab lwm yam, uas yog LED zaub. .

 

7. Greyscale
Greyscale yog hais txog cov degree uas lub luminescence ntawm ib pixel hloov nyob rau hauv lub teeb thiab tsaus ntuj nti, thiab greyscale ntawm ib tug thawj xim feem ntau yog nyob ntawm 8 mus rau 1024. Piv txwv li, yog hais tias lub greyscale ntawm txhua thawj xim yog 256 theem, rau ib tug dual- puag xim xim npo, cov xim zaub yog 256 × 256=64K xim, uas tseem hu ua 256- xim zaub.

 

8. Ob chav xim thawj
Niaj hnub no, feem ntau cov xim LED zaub yog dual-base xim cov ntxaij vab tshaus, uas yog, txhua pixel muaj ob LED tuag: ib tug yog ib tug liab core, thiab lwm yam yog ib tug ntsuab core. Lub pixel yog xim liab thaum lub raj tub ntxhais liab yog ci, lub pixel yog ntsuab thaum lub tube ntsuab yog ci, thiab pixel yog daj thaum liab thiab ntsuab cores ci tib lub sijhawm. Ntawm lawv, liab thiab ntsuab hu ua thawj xim.

 

9. Xim tag nrho
Liab thiab ntsuab ntxiv xiav
