Isithuba esincinci sokubonisa isikrini se-LED, akukho maxhala malunga nomgangatho kunye nokusebenza kakuhle

Ngawaphi amanqaku aphambili ekufuneka abasebenzisi banikele ingqalelo kuwo xa ngokwenene bethenga isiboniso esincinci se-LED?

1. "Ukukhanya okuphantsi kunye nengwevu ephezulu" yinto yokuqala

Njengesixhobo sokubonisa, indawo encinci ye-LED egcwele umbala ogcweleyo kufuneka iqinisekise kuqala ukonwaba kokubukela.Ngoko ke, xa kuthengwa, eyona nto iphambili ixhalabisayo kukukhanya.Uphando olufanelekileyo lubonisa ukuba, ngokumalunga nobuntununtunu bamehlo omntu, i-LED, njengomthombo wokukhanya osebenzayo, ukukhanya kwayo kuphindwe kabini kumthombo wokukhanya we-passive (iprojekthi kunye ne-LCD).Ukuqinisekisa ukuthuthuzeleka kwamehlo abantu, uluhlu olukhanyayo lwendawo encinci enombala ogcweleyo wesiboniso se-LED singaba phakathi kwe-100 cd/㎡ kunye ne-300 cd/㎡.Nangona kunjalo, kwitekhnoloji yokubonisa i-LED egcwele umbala ogcweleyo, ukunciphisa ukukhanya kwesikrini kuya kubangela ukulahleka kwegrey, kwaye ukulahleka kwesikali esingwevu kuya kuchaphazela ngqo umgangatho wesithombe.Ke ngoko, umgangatho wokugweba obalulekileyo wobunjani obuphezulu bendawo encinci enombala ogcweleyo we-LED kukufezekisa isalathiso sobugcisa "sokukhanya okuphantsi kunye negrey ephezulu".Ekuthengeni kwangempela, abasebenzisi banokulandela umgaqo othi "amanqanaba okukhanya ngakumbi anokuthi aqatshelwe ngeso lomntu, ngcono".Inqanaba lokukhanya libhekiselele kwinqanaba lokukhanya komfanekiso ukusuka kumnyama ukuya kumhlophe onokuhlukaniswa ngeliso lomntu.Okukhona imigangatho yokuqaqamba eqondwayo, kokukhona sikhulu isithuba segamut yesikrini sokubonisa, kunye nokuba nkulu ukubakho kokubonisa imibala etyebileyo.

2. Xa ukhetha isithuba seendawo, nikela ingqalelo ekulinganiseni "isiphumo kunye neteknoloji"

Xa kuthelekiswa nescreen se-LED semveli, eyona nto ibalaseleyo yesithuba esincinci esinombala ogcweleyo wescreen se-LED sisithuba esincinci samachaphaza.Kwizinto ezenziwayo ezisebenzayo, okukhona kuncinci isithuba sendawo, kokukhona ubuninzi bepixel buphezulu, kwaye umthamo wolwazi oluninzi kwindawo nganye yeyunithi unokuboniswa ngexesha elinye, ngokukhona umgama ofanelekileyo ukujongwa ukufutshane.Ngokuchasene noko, ukude umgama ofanelekileyo wokujongwa.Abasebenzisi abaninzi ngokwendalo bacinga ukuba okukhona kuncinci isithuba phakathi kwamanqaku emveliso, kokukhona kungcono.Nangona kunjalo, oku akunjalo.Izikrini ze-LED eziqhelekileyo zifuna ukufezekisa iziphumo ezingcono zokubonwa kwaye zibe nomgama ongcono wokujonga, kwaye yenza njalo izikrini ze-LED ezinombala ogcweleyo.Abasebenzisi bangenza izibalo ezilula ngomgama ongcono wokujonga=isithuba sendawo/0.3~0.8.Umzekelo, umgama ongcono wokujonga weP2 isithuba esincinci sesikrini se-LED simalunga neemitha ezi-6 kude.Siyazi ukuba okukhona kuncinci isithuba samachaphaza, kokukhona liphezulu ixabiso lesithuba esincinci esinombala ogcweleyo wesiboniso se-LED.Ngoko ke, ekuthengeni okwenyani, abasebenzisi kufuneka baqwalasele iindleko zabo, imfuno, uluhlu lwesicelo kunye nezinye izinto.

3. Xa ukhetha isisombululo, nikela ingqalelo kungqamaniso kunye "nezixhobo zokuhambisa uphawu lwangaphambili"

Okukhona kuncinci isithuba samachaphaza esibonisiwe se-LED esinombala ogcweleyo, kokukhona siphezulu isisombululo, kunye nokuphezulu kwengcaciso yomfanekiso.Kumsebenzi osebenzayo, ukuba abasebenzisi bafuna ukwakha isixokelelwano esingcono sokubonisa i-LED kunye nesithuba esincinci, kufuneka baqwalasele indibaniselwano yesikrini kunye neemveliso zokuhambisa uphawu lwangaphambili ngelixa benikela ingqalelo kwisisombululo sesikrini ngokwaso.Umzekelo, kwisicelo sokubeka iliso sokhuseleko, inkqubo yokubeka iliso yesiphelo sangaphambili ngokubanzi ibandakanya i-D1, H.264, 720P, 1080I, 1080P kunye nezinye iifomati zeempawu zevidiyo.Nangona kunjalo, ayizizo zonke iziboniso ze-LED ezinendawo encinci ezinombala ogcweleyo kwimarike ezinokuxhasa ezi fomati zeempawu zevidiyo.Ke ngoko, ukuze kuthintelwe inkcitho yemithombo, abasebenzisi kufuneka bakhethe ngokweemfuno zabo xa bethenga iziboniso ze-LED ezinombala ogcweleyo kwindawo encinci, kwaye akufuneki balandele ngokumfamekileyo umkhwa.
