LED Braitnes: Lait bilong wanpela lait-emitting diode (LED) i save kamap long strong bilong lait, ol i save skelim long candela (cd). 1000 μCd (microcandela)=1 mcd (millicandela), 1000 mcd=1 cd. Lait bilong wanpela LED insait long haus em 500 μCd - 50 mcd, na strong bilong lait bilong wanpela LED ausait em 100 mcd - 1000 mcd, o antap long 1000 mcd.
LED Pixel Modules: Ol LED i stap long ol 'matrices' o 'segments' na ol i wokim pastaim long ol 'standard- module'. Ol komon indo displei modul i gat 8x8 piksel modul na 7-segmen dijitel modul. Ol 'outdoor display pixel modules' i stap long 4x4, 8x8, na 8x16 piksel spesifikesen. Bikos wanwan piksel insait long ausait displei i gat tupela o moa LED bandel, ol i kolim tu olsem ol bandel modul.
Piksel na Piksel Diamita: Olgeta wan wan LED lait-emiting yunit (dot) insait long LED displei ol i kolim piksel (o piksel sel). Pixel diameter (∮) i makim diamita bilong wanwan piksel, we ol i skelim long milimita.
Long ol displei insait long haus, ol i save yusim wanpela LED tasol, na em i sekol. Ol 'pixel diameters' we ol i save yusim insait long haus em ∮3.0, ∮3.75, ∮5.0, na ∮8.0, we ∮3.75 na ∮5.0 em ol i nambawan.
Long ol ples ausait, long mekim lait i kamap gutpela na lukluk i go longwe, wanpela piksel i gat tupela o moa 'clustered LED'. Long wanem ol 'clustered LED' i no save sekol, ol i save soim 'pixel diameter' bilong ol 'outdoor displays' olsem averes spes namel long tupela 'pixel': □10, □11.5, □16, □22, □25.
Dot pitch, piksel densiti, na infomesen kapasiti: Senta-i go long-senta distens o dot pitch bilong tupela piksel long wanpela LED displei; namba bilong ol piksel long wanwan yunit eria ol i kolim 'pixel density'; hamas samting i stap long wanwan yunit eria ol i kolim infomesen kapasiti. Dispela tripela tok i tok klia long wankain tingting: 'pixel pitch' i soim 'pixel density' olsem longwe namel long tupela piksel; 'pixel pitch' na 'pixel density' em ol samting bilong soim skrin. Infomesen kapasiti em i kwantitetiv yunit bilong infomesen karim kapasiti bilong piksel densiti.
Sapos 'pixel pitch' i liklik, 'pixel density' i go antap, na infomesen inap long go antap, na longwe bilong lukluk i go klostu.
Taim 'pixel pitch' i bikpela, 'pixel density' i go daun, infomesen kapasiti i go daun, na longwe bilong lukluk i go longwe.
Resolusen: Namba bilong ol lain na kolum bilong ol piksel long wanpela LED displei skrin ol i kolim resolusen. Resolusen em i namba bilong olgeta piksel long skrin, we i makim infomesen kapasiti bilong wanpela displei skrin.
LED Displei Skrin Straksa: Wanpela LED displei skrin em ol i wokim long rot bilong bungim ol LED piksel modul i go insait long wanpela matriks bihainim ol nid tru, wantaim ol dediket displei draiva seket, DC regulet pawa saplai, sofwet, freim, na ol ekstenel dekoresen.
Greiskel: Greiskel i makim mak bilong senis bilong lait bilong wanpela piksel. Wanpela namba wan kala i save gat 8 i go inap 12 greiskel level. Olsem, sapos wanwan praimeri kala i gat 256 grei level, wanpela dual-praimeri-kala skrin inap soim 256 × 256=64k kala, na ol i kolim tu olsem 256-kala displei skrin.
