1. LED Brightness: Lub ci ci ntawm lub teeb -emitting diode feem ntau qhia nyob rau hauv luminous siv, chav tsev uas yog candela (cd); 1000 ucd (microcandela)=1 mcd (millicandela), 1000 mcd=1 cd. Lub luminous siv ntawm ib qho LED rau sab hauv tsev feem ntau yog 500 ucd-50 mcd, thaum lub luminous siv ntawm ib qho LED rau sab nraum zoov siv feem ntau yuav tsum yog 100 mcd-1000 mcd, los yog ntau tshaj 1000 mcd.
2. LED Pixel Module: LEDs tau teeb tsa hauv matrix lossis ntu thiab ua ntej-fabricated rau hauv tus qauv- loj modules. Feem ntau siv modules rau sab hauv tsev muaj xws li 8 * 8 pixel modules thiab 8-seg digital modules. Sab nraum zoov zaub pixel modules muaj specifications xws li 4 * 4, 8 * 8, thiab 8 * 16 pixels. Vim hais tias txhua pixel nyob rau hauv sab nraum zoov zaub modules muaj ntau tshaj li ob LED raj, lawv kuj hu ua pawg modules.
3. Pixel thiab Pixel Diameter: Txhua tus kheej tswj tau LED teeb-emitting unit (dot) nyob rau hauv ib qho screen LED hu ua pixel. Lub pixel txoj kab uas hla ∮ hais txog txoj kab uas hla ntawm txhua pixel, nyob rau hauv millimeters.
4. Kev daws teeb meem: Tus naj npawb ntawm kab thiab kab ntawm pixels hauv ib qho LED zaub yog hu ua kev daws teeb meem ntawm LED zaub. Kev daws teeb meem yog tag nrho cov pixels hauv cov zaub, uas txiav txim siab cov ntaub ntawv muaj peev xwm ntawm lub vijtsam zaub.
5. Greyscale: Greyscale yog hais txog qib ntawm qhov ci variation ntawm pixel lub teeb emission. Greyscale ntawm ib qho xim thawj feem ntau muaj 8 txog 12 qib. Piv txwv li, yog tias qhov grey nplai ntawm txhua qhov xim thawj yog 256 qib, rau ob qho - xim xim thawj, cov xim xim yog 256 × 256=64K xim, tseem hu ua 256-xim zaub.
6. Dual Primary Colors: Feem ntau cov xim LED zaub hnub no yog dual - cov xim xim thawj, txhais tau tias txhua pixel muaj ob lub LED chips: ib qho liab thiab ib qho ntsuab. Thaum lub nti liab teeb, lub pixel yog liab; thaum lub teeb ntsuab yog ci, lub pixel yog ntsuab; thaum ob qho tib si liab thiab ntsuab chips yog ci ib txhij, lub pixel yog daj. Liab thiab ntsuab yog hu ua thawj xim . 7. Xim Xim: Cov xim puv yog ua tiav los ntawm kev sib xyaw xim liab, ntsuab, thiab xiav thawj xim. Txij li cov thev naus laus zis rau xiav thiab ntshiab ntsuab LED chips yog tam sim no paub tab, tag nrho - xim zaub yog feem ntau siv hauv khw.
