Kupenya kwe LED: Kupenya kwechiedza-emitting diode (LED) kazhinji inoratidzwa mukupenya kwakanyanya, kuyerwa necandela (cd). 1000 μCd (microcandela)=1 mcd (millicandela), 1000 mcd=1 cd. Kupenya kwechiedza che LED imwe yemukati kunowanzoita 500 μCd - 50 mcd, ukuwo kupenya kwe LED imwe yekunze kwekunze kunowanzoita 100 mcd - 1000 mcd, kana kutopfuura 1000 mcd.
LED Pixel Modules: MaLED akarongwa mumatrices kana masegmenti uye akagadzirwa kare kuva-saizi modules. Yakajairika indoor kuratidza modules inosanganisira 8x8 pixel modules uye 7-segment dijitari modules. Kunze kwekuratidzira pixel modules anowanikwa mune 4x4, 8x8, uye 8x16 pixel tsanangudzo. Nekuti pixel yega yega muchiratidziro chekunze ine maviri kana anopfuura mabhuru e LED, anonziwo mabundled module.
Pixels nePixel Diameter: Imwe neimwe inodzoreka mwenje we LED-emitting unit (dot) muLED display inonzi pixel (kana pixel cell). Pixel dhayamita (∮) inoreva dhayamita yepixel yega yega, yakayerwa mumamirimita.
Kune zvemukati zviratidziro, LED imwe chete inowanzo shandiswa, uye ine denderedzwa muchimiro. Mapixel madhayamita akajairwa ezviratidziro zvemukati anosanganisira ∮3.0, ∮3.75, ∮5.0, uye ∮8.0, ine ∮3.75 uye ∮5.0 ndiyo inonyanya kuzivikanwa.
Munzvimbo dzekunze, kuvandudza kupenya uye kuwedzera chinhambwe chekutarisa, pixel ine maviri kana anopfuura akabatana maLED. Sezvo ma-clustered LEDs asingawanzo kutenderera, dhayamita yepixel yezviratidziro zvekunze inowanzoratidzwa seavhareji yepakati pakati pemapikisi maviri: □10, □11.5, □16, □22, □25.
Dot pitch, pixel density, uye huwandu hweruzivo: Pakati-ku{1}}pakati pechinhambwe kana kuti dot pitch yemapikisi maviri pachiratidziro cheLED; nhamba yemapikisi pachikamu chimwe chete inonzi pixel density; huwandu hwezvinhu zvakaratidzwa pane imwe nzvimbo inonzi ruzivo ruzivo. Aya mazwi matatu anonyanya kutsanangura pfungwa imwechete: pixel pitch inoratidza pixel density sechinhambwe chiri pakati pepixels mbiri; pixel pitch uye pixel density zvinhu zvemuviri zvechiratidziro. Ruzivo rwehuwandu ndiyo huwandu hwehuwandu hweruzivo hutakura huwandu hwepixel density.
Iyo idiki yepikisi pitch, iyo yakakwira pixel density, iyo yakakura ruzivo ruzivo, uye inoswedera pedyo neakakodzera chinhambwe chekutarisa.
Kukura kwepixel pitch, kuderera kwepixel density, kushomeka kwehuwandu hweruzivo, uye kureba kwakakodzera chinhambwe chekutarisa.
Resolution: Huwandu hwemitsara nemakoramu emapikseli pachiratidzo che LED chinodaidzwa kuti resolution. Resolution ndiyo nhamba yese yepixels pachiratidziro, iyo inotaridza huwandu hweruzivo rwechiratidziro.
Chiratidziro che LED Chiratidziro: Chiratidziro che LED chinogadzirwa nekuunganidza LED pixel modules mune matrix zvinoenderana nezvinodiwa chaizvo, pamwe neakazvitsaurira dhiraivha maseketi, DC inodzorwa magetsi emagetsi, software, mafuremu, uye kunze kwekushongedza.
Grayscale: Grayscale inoreva kupenya kwekusiyana kwepixel. Rudzi rwekutanga kazhinji rune 8 kusvika 12 grayscale mazinga. Semuyenzaniso, kana ruvara rwekutanga rwuine 256 gireyi mazinga, maviri-yeprimary-ruvara sikirini inogona kuratidza 256 × 256=64k mavara, uye inonziwo 256-mavara ekuratidza sikirini.
