LED yeelen: Yeelen-diode (LED) yeelen bɛ jira caman na ni yeelen fanga ye, o bɛ suman ni kandela (cd). 1000 μCd (microcandela)=1 mcd (milikandela), 1000 mcd=1 cd ye. So kɔnɔ LED kelen yeelen fanga bɛ kɛ 500 μCd - 50 mcd ye, ka sɔrɔ kɛnɛma LED kelen yeelen fanga bɛ kɛ 100 mcd - 1000 mcd ye, walima hali ka tɛmɛ 1000 mcd kan.
LED Pixel Modules: LEDw labɛnna matiriyali walima segin-ka-bɔnyew kɔnɔ ani u dilannen don ka kɔn ka kɛ modulu hakɛ dantigɛlenw ye-. So kɔnɔ jiralan modulu minnu bɛ sɔrɔ tuma caman na, olu ye 8x8 pixel modulew ye ani 7-segment digital modules. Kɛnɛma jiralan pixel modules bɛ sɔrɔ 4x4, 8x8 ani 8x16 pixel specifications la. Ikomi kɛnɛma-jiralan kɔnɔ pixel kelen-kelen bɛɛ bɛ Kɛ ni LED kulu fla walima u caman ye, u bɛ Weele fana ko modulu dalajɛlenw.
Pixel ani Pixel Diameter: LED yeelen-bɔlan (dot) kelen-kelen minnu bɛ se ka kɔrɔsi, olu kelen-kelen bɛɛ bɛ LED jiralan kɔnɔ, o bɛ wele ko pixel (walima pixel cell). Pixel diameter (∮) bɛ pixel kelen-kelen bɛɛ cɛmancɛ jira, min bɛ suman milimɛtɛrɛ kɔnɔ.
So kɔnɔ jiralanw kama, a ka c’a la, LED kelen de bɛ kɛ, wa a cogoya ye sɛrɛkili ye. Pixel cɛmancɛ minnu bɛ sɔrɔ so kɔnɔ jiralanw na olu ye ∮3.0, ∮3.75, ∮5.0 ani ∮8.0 ye, ∮3.75 ani ∮5.0 de ka ca kosɛbɛ.
Kɛnɛma sigidaw la, walasa ka yeelen bonya ani ka dɔ fara filɛli yɔrɔ kan, pixel kelen kɔnɔ, LED kulu fila walima u caman bɛ sɔrɔ. Ikomi a ka c’a la, LED kuluw tɛ sɛrɛkili ye, a ka c’a la, kɛnɛma jiralanw pixel cɛmancɛ bɛ jira iko pixel fila ni ɲɔgɔn cɛ janya cɛmancɛ: □10, □11.5, □16, □22, □25.
Dot pitch, pixel density, ani information capacity: Pixel fila cɛmancɛ-ka taa{1}}cɛmancɛ janya walima dot pitch LED jiralan kan; pixel hakɛ min bɛ yɔrɔ kelen na, o bɛ wele ko pixel density; kɔnɔkow jiralen hakɛ min bɛ yɔrɔ kelen na, o bɛ wele ko kunnafoni seko. Nin daɲɛ saba ninnu bɛ hakilina kelen ɲɛfɔ tigitigi: pixel pitch bɛ pixel density jira i n’a fɔ pixel fila o fila ni ɲɔgɔn cɛ janya; pixel pitch ani pixel density ye jiralan ɛkran farikolomafɛnw ye. Kunnafoni seko ye kunnafoni ta seko hakɛlama ye min bɛ pixel density (pixel density) la.
Ni pixel (piksɛl) hakɛ ka dɔgɔn, pixel (pixel) hakɛ bɛ caya, kunnafoni-di-se bɛ bonya, wa, filɛli yɔrɔ bɛnnen bɛ surunya.
Ni pixel (piksɛl) hakɛ ka bon, pixel (piksɛl) hakɛ bɛ dɔgɔya, kunnafoni-falen-falen-se bɛ dɔgɔya, wa, filɛli yɔrɔ bɛnnen bɛ taa yɔrɔ jan.
Ɲɛfɔli: Pixel (piksɛl) kuluw ni kuluw hakɛ min bɛ LED jiralan kan, o bɛ wele ko resolution. Resolution ye pixel hakɛ bɛɛ ye min bɛ ɛkran kan, o min bɛ jiralan dɔ ka kunnafoni seko dantigɛ.
LED jiralan ɛkran jɔcogo: LED jiralan ɛkran bɛ dilan ni LED pixel moduluw lajɛli ye ka kɛ matirili ye ka kɛɲɛ ni mago lakikaw ye, ka fara jiralan bolibaga ciriw kɛrɛnkɛrɛnnenw kan, DC regulated power supplys, software, frames, ani kɛnɛma masirifɛnw.
Grayscale: Grayscale bɛ tali kɛ pixel (piksɛl) ka yeelen caman ɲɔgɔnna hakɛ la. A ka c’a la, kulɛri fɔlɔ bɛ kɛ ni 8 fo 12 ye. Misali la, ni kulɛri fɔlɔ kelen-kelen bɛɛ ye nivo 256 ye, kulɛri ɛkran fila-kɔrɔlen- bɛ se ka kulɛri 256 × 256=64k jira, wa a bɛ wele fana ko kulɛri 256 jiralan.
