Kusankhidwa kwa malo owonetsera ma LED kumagwirizana ndi zinthu ziwiri:
Choyamba, mtunda wowonera wa chiwonetsero cha LED
Kodi chinsalu chowonetsera chimayikidwa pati, komanso momwe anthu amaimirira kuti azichiyang'ana, ndizofunikira kwambiri pozindikira madontho posankha chophimba cha LED.
Nthawi zambiri, pali njira yowonera mtunda woyenera = dot pitch/(0.3~0.8), womwe ndi pafupifupi mulingo.Mwachitsanzo, pachiwonetsero chokhala ndi pixel pitch ya 16mm, mtunda wabwino kwambiri wowonera ndi 20 ~ 54 metres.Ngati mtunda wa siteshoni uli pafupi ndi mtunda wocheperako, mutha kusiyanitsa ma pixel a skrini yowonetsera.The graininess ndi wamphamvu, ndipo inu mukhoza kuima patali.Tsopano, diso la munthu silingathe kusiyanitsa mbali za mwatsatanetsatane.(Timayang'ana masomphenya abwinobwino, kupatula myopia ndi hyperopia).M'malo mwake, ichi ndi chithunzi chovuta.
Kwa zowonetsera zakunja za LED, P10 kapena P12 nthawi zambiri amagwiritsidwa ntchito mtunda waufupi, P16 kapena P20 kwa otalikirapo, ndi P4~P6 zowonetsera zamkati, ndi P7.62 kapena P10 zakutali.
Chachiwiri, chiwerengero chonse cha ma pixel a chiwonetsero cha LED
Pakanema, mawonekedwe oyambira ndi VCD yokhala ndi malingaliro a 352288, ndipo mtundu wa DVD ndi 768576. Choncho, pazithunzi za kanema, timalimbikitsa kuti chigamulo chochepa sichichepera 352 * 288, kotero kuti zotsatira zowonetsera ndizokwanira.Ngati ili m'munsi, ikhoza kuwonetsedwa, koma sichidzapindula bwino.
Pazowonetsera zamtundu umodzi komanso wapawiri wamtundu wa LED womwe umawonetsa kwambiri zolemba ndi zithunzi, zofunikira sizokwera.Kutengera kukula kwenikweni, mawonekedwe ochepera a font 9 amatha kutsimikiziridwa molingana ndi kuchuluka kwa mawu anu.
Chifukwa chake, nthawi zambiri sankhani chiwonetsero cha LED, kuchepera kwa kadontho, kumakhala bwinoko, mawonekedwe ake amakhala apamwamba, ndipo chiwonetserocho chizikhala chomveka.Komabe, zinthu monga mtengo, kufunikira, ndi kuchuluka kwa ntchito ziyeneranso kuganiziridwa mozama.
