Ndi chitukuko chofulumira chaukadaulo wowonetsa wa LED, zowonetsa za LED zikuwonetsa chitukuko chosiyanasiyana. Masiku ano zowonetsera zowonetsera za LED zimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Komabe, kwa oyamba kumene, mawu ambiri aukadaulo owonetsera a LED amagwiritsidwa ntchito. Sindikudziwa, ndiye ndi mawu ati omwe amagwiritsidwa ntchito popanga ma LED?
Kuwala kwa LED: Kuwala kwa diode yotulutsa kuwala kumawonetsedwa ndi Kuwala Kwambiri mu magawo a Candela cd; 1000ucd (micro-candela) = 1 mcd (chitunda candela), 1000mcd = 1 cd. Kukula kwamphamvu kwa LED imodzi yogwiritsa ntchito m'nyumba nthawi zambiri kumakhala 500ucd-50 mcd, pomwe kuwala kwa LED imodzi yogwiritsa ntchito panja kuyenera kukhala 100 mcd-1000 mcd kapena 1000 mcd kapena kupitilira apo.
Gawo la pixel ya LED: Ma LED amakonzedwa mu gawo la cholembera kapena cholembera, ndipo amasankhidwa kukhala ma module oyambira. Kanema wowonetsera wamkati omwe amagwiritsidwa ntchito modula 8 * 8 pixel, 8 word 7-segment module. Ma pixel owonetsa panja ali ndi mafotokozedwe monga 4 * 4, 8 * 8, 8 * 16 pixels. Module ya pixel yowonetsera panja imadziwikanso kuti gawo lamutu wamutu chifukwa pixel iliyonse imakhala ndi ma thumba awiri kapena kupitilira apo a LED.
Pixel ndi Pixel Diameter: Chowunikira chilichonse chowunikira cha LED (kadontho) kamene kamatha kuyang'aniridwa pakuwonetsera kwa LED kumatchedwa pixel (kapena pixel). Mapikiselo a pixel ∮ amatanthauza kukula kwa pixel iliyonse mamilimita.
Maonekedwe: Chiwerengero cha mizere ndi mizati yama pixels owonetsera a LED chimatchedwa chisankho cha chiwonetsero cha LED. Chisankhocho ndi chiwonetsero chonse cha ma pixels omwe akuwonetsedwa, omwe amatsimikizira kuchuluka kwazowonetsera.
Mvi yayikulu: Gulu loyera limatanthauza momwe kuwala kwa pixel kumasinthira. Mtundu wakuda wamtundu woyamba umakhala ndi magawo 8 mpaka 12. Mwachitsanzo, ngati imvi pamtundu uliwonse woyambirira ndi ma 256, pamitundu iwiri yoyang'ana utoto, mtundu wowonetsera ndi 256 × 256 = 64K mtundu, womwe umadziwikanso kuti chiwonetsero chazithunzi 256.
Mitundu yapawiri yapawiri: Mawonekedwe ambiri amtundu wa LED masiku ano ndi makanema oyambira awiri, ndiko kuti, pixel iliyonse imakhala ndi ma LED awiri omwe amafa: imodzi ya ofiira ofiira ina ndi yobiriwira yobiriwira. Mapikiselo amakhala ofiira pomwe ofiira amafiira, mtunduwo umakhala wobiriwira pomwe wobiriwirayo umawala, ndipo pixel yake imakhala yachikaso ikafa yofiira komanso yobiriwira nthawi yomweyo. Pakati pawo, ofiira ndi obiriwira amatchedwa mitundu yoyamba.
Mtundu wathunthu: utoto wofiyira komanso wobiriwira wapawiri wowonjezera kuphatikiza utoto wabuluu, mitundu itatu yoyamba imapanga utoto wonse. Popeza ukadaulo wopanga machubu amtundu wabuluu ndikufa wobiriwira wangwiro tsopano ndi wokhwima, msikawo ndiwodzaza.
SMT ndi SMD: SMT ndiye ukadaulo wapamwamba (wopitilira Surface Mounted Technology), womwe ndi ukadaulo wotchuka kwambiri pakampani yamagetsi yamagetsi; SMD ndichida chokwera pamwamba (chidule cha chipangizo chokwera pamwamba)
