1. LED Brightness
Teb: LED ci ci yog hais txog lub teeb ci ntawm lub teeb -emitting diode, ntsuas hauv candela (cd). Lub luminous siv ntawm ib lub LED sab hauv tsev feem ntau yog 500 microcandela (ucd) mus rau 50 millicandela (mcd), thaum lub luminous siv ntawm ib lub LED sab nraum zoov feem ntau yog 100 mcd rau 1000 mcd, los yog ntau dua. Brightness yog ib qho ntawm cov cim tseem ceeb rau kev ntsuam xyuas qhov pom ntawm qhov screen LED.
2. LED Pixel Module
Teb: Ib qho LED pixel module hais txog ib qho module uas LEDs tau teem rau hauv matrix lossis ntu thiab prefabricated rau tus qauv loj. Feem ntau siv modules rau sab hauv tsev yog 88-pixel modules thiab 7-seg digital modules, thaum sab nraum zoov pixel modules muaj nyob rau hauv 44, 88, thiab 816 pixel specifications. Sab nraum zoov zaub pixel modules kuj hu ua bundled LED modules vim hais tias txhua pixel muaj ob los yog ntau tshaj LED bundles . 3. Pixel thiab Pixel Diameter
Teb: Nyob rau hauv ib qho LED zaub, txhua tus kheej tswj tau LED teeb -emitting unit (dot) hu ua pixel (los yog duab). Lub pixel txoj kab uas hla (∮) yog hais txog txoj kab uas hla ntawm txhua pixel, ntsuas hauv millimeters. Qhov loj ntawm pixel kab ncaj qha cuam tshuam rau qhov kev daws teeb meem thiab qhov ntse ntawm cov zaub.
4. Kev daws teeb meem
Teb: Qhov kev daws teeb meem ntawm LED zaub yog hais txog cov kab thiab kab ntawm nws cov pixels. Kev daws teeb meem yog tag nrho cov pixels ntawm cov zaub, uas txiav txim siab cov ntaub ntawv muaj peev xwm thiab cov nyhuv ntawm cov zaub. Qhov siab dua qhov kev daws teeb meem, cov ntaub ntawv ntau dua cov zaub tuaj yeem pom, thiab cov duab pom tseeb dua.
5. Greyscale
Teb: Greyscale hais txog qib ntawm qhov ci variation ntawm ib pixel. Thawj xim feem ntau muaj 8 txog 12 qib grey. Qhov siab dua qib grayscale, cov xim gradation ntawm cov zaub ntau dua, thiab cov duab zoo dua. Piv txwv li, yog tias txhua qhov xim thawj muaj 256 qib greyscale, ib qho screen dual - xim tuaj yeem tso tawm 256 × 256=64K xim, tseem hu ua 256-xim zaub. 6. Dual-Primary Xim
Teb: Lub dual -thawj- xim LED zaub yog hais txog cov zaub uas txhua pixel muaj ob lub LED chips: ib qho liab thiab ib qho ntsuab. Thaum lub nti liab teeb, lub pixel qhia liab; thaum lub nti ntsuab yog ci, lub pixel qhia ntsuab; thiab thaum ob lub chips ci ib txhij, lub pixel qhia daj. Liab thiab ntsuab yog hu ua thawj xim. Los ntawm kev kho qhov ci piv txwv ntawm liab thiab ntsuab, cov xim sib txawv tuaj yeem pom.
7. Puv -xim
Teb: Ib daim ntawv qhia tag nrho -xim LED yog hais txog cov zaub uas ntxiv xiav thawj xim rau dual-thawj- xim zaub, ua rau muaj tag nrho - xim zaub. Txij li thaum cov thev naus laus zis siv xiav thiab ntshiab ntsuab LED chips los tsim tag nrho - xim cov duab yog cov paub tab, feem ntau LED zaub hauv khw siv tag nrho - xim technology. Tag nrho- xim xim tuaj yeem tso saib cov xim nplua nuj thiab cov duab tiag tiag, sawv cev rau kev taw qhia tseem ceeb hauv kev txhim kho LED zaub technology.
