Obutangaavu bwa LED: Obutangaavu bwa dayode efulumya ekitangaala- (LED) okutwalira awamu bulagibwa mu maanyi g’ekitangaala, nga bupimibwa mu kandela (cd). 1000 μCd (microcandela)=1 mcd (millicandela), 1000 mcd=1 cd. Amaanyi g’ekitangaala kya LED emu ey’omunda gatera kuba 500 μCd - 50 mcd, ate amaanyi g’ekitangaala kya LED emu ey’ebweru gatera kuba 100 mcd - 1000 mcd, oba wadde waggulu wa 1000 mcd.
LED Pixel Modules: LEDs zisengekebwa mu matrices oba segments era ne zikolebwa nga tezinnabaawo mu modules eza standard-sized. Module z’okulaga munda eza bulijjo mulimu modulo za 8x8 pixel ne modulo za digito ez’ebitundu 7. Module za pixel ez’okulaga ebweru zisangibwa mu 4x4, 8x8, ne 8x16 pixel specifications. Olw’okuba buli pixel mu display ey’ebweru erimu ebibumbe bya LED bibiri oba okusingawo, era biyitibwa modulo ezikuŋŋaanyiziddwa.
Pixels ne Pixel Diameter: Buli kitundu ekifulumya ekitangaala kya LED-ekifugibwa kinnoomu (dot) mu kifaananyi kya LED kiyitibwa pixel (oba pixel cell). Dyaamu ya pikseli (∮) kitegeeza dayamita ya buli ppikisi, epimiddwa mu milimita.
Ku by’okwolesebwa eby’omunda, LED emu etera okukozesebwa, era ya ngeri ya nneekulungirivu. Dyaamu za pikseli eza bulijjo ez’okwolesebwa okw’omunda mulimu ∮3.0, ∮3.75, ∮5.0, ne ∮8.0, nga ∮3.75 ne ∮5.0 ze zisinga okubeera.
Mu mbeera ez’ebweru, okulongoosa okwaka n’okwongera ku bbanga ly’okulaba, pixel erimu LED bbiri oba okusingawo ezikuŋŋaanyiziddwa. Okuva LED ezikuŋŋaanyiziddwa okutwalira awamu bwe zitali za nneekulungirivu, obuwanvu bwa pikseli obw’okulaga ebweru butera okulagibwa ng’ebanga erya wakati wakati wa ppikisi bbiri: □10, □11.5, □16, □22, □25.
Eddoboozi ly’ennyiriri, obungi bwa pikseli, n’obusobozi bw’amawulire: Ebanga wakati-okutuuka ku-amasekkati oba eddoboozi ly’ennukuta erya ppikisi bbiri ku kifaananyi kya LED; omuwendo gwa ppikisi buli yuniti y’ekitundu guyitibwa ppikisi density; omuwendo gw’ebirimu ebiragiddwa buli kitundu kya yuniti guyitibwa obusobozi bw’amawulire. Ebigambo bino ebisatu mu bukulu binnyonnyola endowooza y’emu: eddoboozi lya pikseli liraga density ya pikseli ng’ebanga wakati wa ppikisi zonna ebbiri; pixel pitch ne pixel density bye bintu ebirabika eby’olutimbe lw’okulaga. Obusobozi bw’amawulire ye yuniti y’omuwendo (quantitative unit) ey’obusobozi bw’okutwala amawulire obwa pixel density.
Eddoboozi lya pikseli gye likoma okuba entono, density ya pikseli gyekoma okuba waggulu, obusobozi bw’amawulire gye bukoma okuba obunene, era n’ebanga erisaanira ery’okulaba gye likoma okubeera okumpi.
Eddoboozi lya pixel gye likoma okuba ennene, density ya pixel gyekoma okuba wansi, obusobozi bw’amawulire gye bukoma okuba obutono, era n’ebanga erisaanira okulaba gye likoma okuba ewala.
Okusalawo: Omuwendo gw’ennyiriri n’ennyiriri za ppikisi ku ssirini y’okulaga LED guyitibwa okusalawo. Resolution gwe muwendo gwonna ogwa pixels ku screen, ogusalawo obusobozi bw’amawulire obwa screen eraga.
Enzimba ya LED Display Screen Structure: LED display screen ekolebwa nga ekuŋŋaanya modulo za LED pixel mu matrix okusinziira ku byetaago byennyini, wamu ne circuits za ddereeva display eziweereddwayo, DC regulated power supplies, software, frames, n’okuyooyoota ebweru.
Enzirugavu: Enzirugavu kitegeeza diguli y’enkyukakyuka y’okumasamasa kwa pikseli. Langi enkulu etera okuba n’emitendera egy’enzirugavu 8 ku 12. Okugeza, singa buli langi enkulu eba n'emitendera enzirugavu 256, olutimbe lwa langi bbiri-olubereberye- lusobola okulaga langi 256 × 256=64k, era era luyitibwa olutimbe lw'okulaga langi 256.
