Imaphi amaphuzu abalulekile abasebenzisi okufanele banake lapho bethenga isibonisi esincane se-LED?
1. "Ukukhanya okuphansi kanye nokumpunga okuphezulu" isisekelo
Njengetheminali yokubonisa, isikrini se-LED esinombala ogcwele esikhala esincane kufanele siqale siqinisekise ukunethezeka kokubuka.Ngakho-ke, lapho uthenga, ukukhathazeka okuyinhloko ukukhanya.Ucwaningo olufanele lubonisa ukuthi, mayelana nokuzwela kwamehlo omuntu, i-LED, njengomthombo wokukhanya osebenzayo, ukukhanya kwayo kuphindwe kabili komthombo wokukhanya we-passive (iphrojekthi ne-LCD).Ukuqinisekisa ukunethezeka kwamehlo omuntu, ububanzi bokukhanya besikhala esincane esinombala ogcwele wesibonisi se-LED singaba kuphela phakathi kuka-100 cd/㎡ no-300 cd/㎡.Kodwa-ke, kubuchwepheshe besibonisi be-LED obunemibala egcwele, ukwehlisa ukukhanya kwesikrini kuzodala ukulahleka kwesikali esimpunga, futhi ukulahlekelwa kwesikali esimpunga kuzothinta ikhwalithi yesithombe ngokuqondile.Ngakho-ke, indinganiso yokwahlulela ebalulekile yesibonisi se-LED esinemibala egcwele yekhwalithi ephezulu siwukufinyelela inkomba yobuchwepheshe "yokukhanya okuphansi nokumpunga okuphezulu".Ekuthengeni kwangempela, abasebenzisi bangalandela isimiso sokuthi "amaleveli amaningi okukhanya angabonwa ngeso lomuntu, aba ngcono".Izinga lokukhanya libhekisela ezingeni lokukhanya kwesithombe kusuka kokumnyama kuya kokumhlophe okungahlukaniswa ngeso lomuntu.Amaleveli okukhanya aqashelwa kakhulu, sikhulu isikhala se-gamut sesikrini sokubonisa, namandla okubonisa imibala ecebile.
2. Lapho ukhetha isikhala sephoyinti, naka ukulinganisa "umphumela nobuchwepheshe"
Uma kuqhathaniswa nesikrini se-LED esivamile, isici esivelele sesikrini esincane se-LED esinemibala egcwele isikhala esincane samachashazi.Ezinhlelweni ezingokoqobo, lapho isikhala sephoyinti siba sincane, kulapho ukuminyana kwamaphikseli kuba phezulu, futhi umthamo wolwazi owengeziwe endaweni yeyunithi ngayinye ungaboniswa ngesikhathi esisodwa, lisondelana nebanga elifanele ukubukwa.Ngokuphambene nalokho, ibanga elifanele ukulibuka liya kude.Abasebenzisi abaningi ngokwemvelo bacabanga ukuthi isikhala esincane phakathi kwamaphoyinti omkhiqizo, siba ngcono.Nokho, akunjalo.Izikrini ze-LED ezivamile zifuna ukuzuza imiphumela engcono yokubuka futhi zibe nebanga elingcono lokubuka, kanjalo nezikrini ze-LED ezinezikhala ezincane ezinombala ogcwele.Abasebenzisi bangenza izibalo ezilula ngokusebenzisa ibanga elingcono lokubuka=isikhala sephoyinti/0.3~0.8.Isibonelo, ibanga elingcono lokubuka lesikrini se-LED esinezikhala esincane se-P2 cishe siqhele ngamamitha angu-6.Siyazi ukuthi uma isikhala samachashazi sincane, izindleko zesikhala esincane esinemibala egcwele ye-LED yesibonisi ziba phezulu.Ngakho-ke, ekuthengeni kwangempela, abasebenzisi kufanele bacabangele izindleko zabo, isidingo, ububanzi bohlelo nezinye izici.
3. Lapho ukhetha isixazululo, qaphela ukumatanisa “nemishini yokudlulisela isignali yangaphambili”
Ukuncane kwesikhala samachashazi sesibonisi se-LED esinombala ogcwele wephimbo elincane, kuphakama ukulungiswa, kanye nencazelo yesithombe ephezulu.Ekusebenzeni okungokoqobo, uma abasebenzisi befuna ukwakha isistimu yokubonisa ye-LED engcono enezikhala ezincane, kufanele futhi bacabangele inhlanganisela yesikrini kanye nemikhiqizo yokudlulisa isignali yangaphambili ekugcineni kuyilapho benaka ukulungiswa kwesikrini ngokwaso.Isibonelo, kuhlelo lokusebenza lokuqapha ukuphepha, isistimu yokuqapha yangaphambili ngokuvamile ihlanganisa i-D1, H.264, 720P, 1080I, 1080P namanye amafomethi amasignali evidiyo.Nokho, akuzona zonke izibonisi ze-LED ezinombala ogcwele endaweni encane emakethe ezingasekela amafomethi angenhla amasignali evidiyo.Ngakho-ke, ukuze kugwenywe ukumoshakala kwezisetshenziswa, abasebenzisi kufanele bakhethe ngokuya ngezidingo zabo lapho bethenga izibonisi ze-LED ezinendawo encane enombala ogcwele, futhi akumele balandele ngokumpumputhe umkhuba.
