Nigute ushobora guhitamo LED yerekana akadomo

Guhitamo LED yerekana umwanya ujyanye nibintu bibiri:
Ubwa mbere, kureba intera ya LED yerekana
Nihe ecran yerekana yashyizwe, nuburyo abantu bahagaze kugirango bayirebe, nikintu cyingenzi muguhitamo akadomo muguhitamo LED yerekana ecran.
Mubisanzwe, hari formulaire yo kureba neza intera = akadomo / (0.3 ~ 0.8), ni intera igereranijwe.Kurugero, kugirango yerekanwe hamwe na pigiseli ya 16mm, intera nziza yo kureba ni metero 20 ~ 54.Niba intera ihagaze hafi yintera ntoya, urashobora gutandukanya pigiseli yerekana ecran.Ingano irakomeye, kandi urashobora guhagarara kure.Noneho, ijisho ryumuntu ntirishobora gutandukanya ibiranga ibisobanuro.(Dufite intego yo kureba bisanzwe, ukuyemo myopiya na hyperopiya).Mubyukuri, iyi nayo ni ishusho itoroshye.
Kuri ecran ya LED yo hanze, P10 cyangwa P12 mubisanzwe bikoreshwa mumwanya muto, P16 cyangwa P20 kubireba kure, na P4 ~ P6 mubyerekanwe murugo, na P7.62 cyangwa P10 kubireba kure.
Icya kabiri, umubare rusange wa pigiseli ya LED yerekana
Kuri videwo, imiterere y'ibanze ni VCD ikemurwa na 352288, naho format ya DVD ni 768576. Kubwibyo, kuri ecran ya videwo, turasaba ko ibyemezo byibura bitarenze 352 * 288, kugirango ingaruka zo kwerekana zibe nziza bihagije.Niba ari hasi, irashobora kwerekanwa, ariko ntabwo izagera kubisubizo byiza.
Kubara rimwe kandi ryibiri ryibanze LED yerekana cyane cyane inyandiko n'amashusho, ibisabwa byo gukemura ntabwo biri hejuru.Ukurikije ingano nyayo, byibuze kwerekana imyandikire ya 9 birashobora kugenwa ukurikije ingano yinyandiko.
Kubwibyo, muri rusange hitamo LED yerekana, ntoya ya dot ikibanza, nibyiza, nibisubizo bizaba hejuru, kandi ibyerekanwe bizasobanuka.Ariko, ibintu nkigiciro, ibisabwa, nubunini bwikurikizwa bigomba nanone gusuzumwa neza.
