Kala na gutpela lait bilong ol LED i go wantaim ol samting na pasin ol i yusim long wokim ol. Red, grin, na blu em ol kala we planti manmeri i save yusim. Bikos ol LED displei i save wok long liklik volteji (5V tasol), ol i ken givim lait wantaim wanpela kain lait we ol i ken stretim long volteji (o karent), na ol i no inap long bagarap, ol i no inap guria, na ol i gat longpela laipspan (100,000 aua), i no gat narapela rot bilong soim ol LED displei inap long winim ol bikpela displei ikwipmen.
Wanpela displei skrin we i bungim ol retpela na grinpela LED olsem wanpela piksel tasol ol i kolim tupela-kala skrin o ful-kala skrin; wanpela displei skrin we i bungim ol retpela, grinpela, na blupela LED olsem wanpela piksel tasol ol i kolim tri-kala skrin o ful-kala skrin. Ol LED skrin insait long haus i save gat piksel sais bilong 2-20 mm, na planti taim ol i save yusim planti LED sip we i save kamapim ol narapela narapela kala we ol i putim wantaim. Ol LED skrin ausait i save gat piksel sais bilong 8-32 mm, na wan wan piksel i gat sampela wan wan monokrom LED. Ol samting we ol i save wokim pinis ol i kolim 'pixel tubes'; tupela kala piksel tiub i save gat 2-pela ret na 1 grin LED, na tripela kala piksel tiub i gat 1 ret, 1 grin, na 1 blu LED.
Maski yu yusim ol LED long wokim ol skrin we i gat wankain kala, tupela kala, o tripela kala, lait bilong wanwan LED we i kamapim wanpela piksel i mas senis long soim piksa. Gutpela bilong dispela stretim em ol i kolim 'grayscale level' bilong 'display screen'. Sapos 'grayscale level' i go antap, piksa bai kamap gutpela moa, ol kala bai kamap gutpela moa, na 'display control system' i gat planti samting long en. Planti taim, wanpela 256-level greiskel piksa i gat gutpela kala senis, na wanpela 16-level greiskel kala piksa i gat ol klia kala senis baundri. Olsem na, ol kala LED skrin bilong nau i mas gat 256 i go inap 4096 greiskel level.
Ol LED luminescent materiel we ol i yusim long ol displei i gat ol dispela kain:
Ol LED lam (o wanpela lam): Planti taim ol i gat wanpela LED sip, wanpela 'reflector', wanpela 'metal anode', na wanpela 'metal cathode', we i stap insait long wanpela 'epoxy resin shell' we i gat strong bilong bungim lait. Wanpela o moa (ol narapela narapela kala) singel lam inap long kamapim wanpela besik piksel. Bikos ol i gat bikpela lait, ol i save yusim ol long ol ausait displei.
LED dot matrix modules: Em i gat planti 'chips' we i kamapim wanpela 'luminescent matrix', na i stap insait long wanpela 'epoxy resin shell' insait long wanpela 'plastic shell'. Em i gutpela long ol 'row' na 'column scanning' draiv, em i isi long wokim ol 'high-density displays, na planti taim ol i save yusim long ol 'indoor displays'.
Ol 'surface mount LEDs' (o SMD LEDs) em ol LED insait long wanpela 'surface mount package', we i gutpela long ol ful-kala displei insait long haus, na i larim wanpela '-pela poin mentenens na i winim gut ol 'mosaic effects'.
