Hasken LED: Hasken haske -emitting diode (LED) ana bayyana shi gabaɗaya cikin ƙarfi mai haske, ana auna shi a candela (cd){1}} μCd (microcandela)=1 mcd (millicandela), 1000 mcd=1 cd. Hasken haske na LED guda ɗaya na cikin gida shine yawanci 500 μCd - 50 mcd, yayin da ƙarfin hasken LED guda ɗaya na waje shine yawanci 100 mcd - 1000 mcd, ko ma sama da 1000 mcd.
Modulolin Pixel na LED: Ana shirya LEDs a cikin matrices ko sassa kuma an riga an ƙirƙira su zuwa daidaitattun kayayyaki masu girma -. Modulolin nuni na cikin gida gama gari sun haɗa da 8x8 pixel modules da 7-segment modules dijital. Ana samun samfuran pixel nunin waje a cikin ƙayyadaddun pixel 4x4, 8x8, da 8x16 pixel. Domin kowane pixel a cikin nunin waje ya ƙunshi nau'ikan LED guda biyu ko fiye, ana kuma kiran su da haɗaɗɗun kayayyaki.
Pixels da Diamita na Pixel: Kowace hasken LED mai iya sarrafa ɗaiɗaiku {{0}maitting unit (dot) a cikin nunin LED ana kiransa pixel (ko pixel cell). Diamita na pixel (∮) yana nufin diamita na kowane pixel, wanda aka auna a millimeters.
Don nuni na cikin gida, LED guda ɗaya ana amfani da shi yawanci, kuma yana da madauwari a siffa. Diamita na pixel gama-gari don nunin cikin gida sun haɗa da ∮3.0, ∮3.75, ∮5.0, da ∮8.0, tare da ∮3.75 da ∮5.0 waɗanda suka fi kowa.
A cikin mahalli na waje, don haɓaka haske da haɓaka nisan kallo, pixel yana ƙunshe da manyan LED guda biyu ko fiye. Tunda fitattun LEDs gabaɗaya ba madauwari bane, diamita na pixel don nunin waje yawanci ana bayyana shi azaman matsakaicin tazara tsakanin nau'ikan pixels: □10, □11.5, □16, □22, □25.
Ƙimar digo, ƙimar pixel, da ƙarfin bayanai: Tsararraki{0}zuwa{1}}tsakiya ko farar digo na pixels biyu akan nunin LED; ana kiran adadin pixels a kowane yanki na yanki; Adadin abun ciki da aka nuna a kowane yanki ana kiransa ƙarfin bayanai. Waɗannan sharuɗɗan uku da gaske suna bayyana ra'ayi iri ɗaya: ƙimar pixel yana nuna ƙimar pixel a matsayin nisa tsakanin kowane pixels biyu; pixel pitch da pixel density abubuwa ne na zahiri na allon nuni. Ƙarfin bayanai shine sashin ƙididdigewa na bayanin da ke ɗauke da ƙarfin ƙimar pixel.
Karamin farar pixel, mafi girman girman pixel, mafi girman ƙarfin bayanai, kuma mafi kusancin nisan kallo mai dacewa.
Girman farar pixel, ƙananan ƙimar pixel, ƙarancin ƙarfin bayanai, kuma mafi nisa nisan kallo mai dacewa.
Resolution: Adadin layuka da ginshiƙan pixels akan allon nunin LED ana kiran su ƙuduri. Resolution shine jimlar adadin pixels akan allon, wanda ke ƙayyade ƙarfin bayanin allon nuni.
Tsarin Allon Nuni na LED: An gina allon nunin LED ta hanyar haɗa nau'ikan pixels na LED a cikin matrix bisa ga ainihin buƙatu, tare da keɓaɓɓun keɓaɓɓun da'irorin direbobi, DC ɗin sarrafa wutar lantarki, software, firam, da adon waje.
Grayscale: Grayscale yana nufin matakin bambancin haske na pixel. Launi na farko yawanci yana da matakan launin toka 8 zuwa 12. Misali, idan kowane launi na farko yana da matakan launin toka 256, allon launi guda biyu- na farko{6} zai iya nuna launuka 256 × 256=64, kuma ana kiransa allon nuni mai launi 256.
