Yini ukukhanya kwesikrini?
Ukukhanya kwesikrini sokubonisa esiholwa kubhekisele ekujuleni kokukhanya okukhishwe yi-LED yangaphakathi (ama-diode akhanyise amanga). Imvamisa, sisebenzisa i-CD / M² (i-Candela Per Meters) noma ama-Nits njengeyunithi ukukala ukukhanya kwesikrini se-LED. Ukwanda kwenani lokukhanya kukhombisa ukuthi isibonisi se-LED sikhipha ukukhanya okunamandla. Isibonelo, isikrini sangaphandle se-LED esinezinkulungwane ezingama-10,000 zokukhanya zigqamile kakhulu kunesikrini sangaphakathi endlini enezilwane ezingama-800 kuphela.
Ukubaluleka kokukhanya kwesikrini kwe-LED
Ukuguqulwa kwezindawo ezahlukahlukene
Ukukhanya kwesikrini se-LED kubalulekile ekuvumelaneni nezimo ezahlukene. Ukukhetha izinga lokukhanya okulungile akugcini kuqinisekisa ukuvumelana nemvelo kodwa futhi kuthuthukisa ukusebenza kahle kwezomnotho kwesikrini se-LED.
Umthelela ekusebenzeni okuphelele
Ukukhanya kuthinta kakhulu ezinye izinkomba zokusebenza kwesikrini se-LED, njengokuqhathanisa, i-greycale, kanye nemibala. Ukukhanya okunganele kunomthelela ngqo ekusebenzeni kwesikrini kulezi zindawo, okunquma kakhulu ikhwalithi ephelele yesibonisi se-LED.
I-angle yokubuka engaguquki
Ukukhanya okuphezulu kuvumela ukucaciswa kwesithombe okungaguquki ngaphesheya kwe-angle ebuka kakhulu. Lokhu kusho ukuthi noma ngabe kubukwa kusukela kuma-engeli okungewona aphakathi, isikrini esikhanyayo esiphakeme singaqinisekisa ukuboniswa kokuqukethwe okucacile, kanti isikrini sokukhanya okuphansi singalwa nokucoca ukucaca emaphethelweni.
Uhla olubanzi lwezicelo
Izikrini eziphakeme zokukhanya okuphezulu zinezinhlobonhlobo zezicelo, zilungele izindawo ezifana nezitolo zezitolo, izikhungo zezindiza, izindawo zemidlalo, kanye nezindawo zokuhamba, kanye nezindawo zokuhamba ezidinga ukubonakala okuphezulu nekhwalithi yesithombe. Ngokuphambene nalokho, izikrini eziholwa ngokukhanya okuphansi zivame ukukhawulelwa ezindaweni ezingaphakathi endlini noma ezikhanyayo.
Indlela yokunquma ukugqama kwesikrini esifanelekile
Ngenkathi ukukhanya okuphezulu kuyinzuzo enkulu yezikrini ze-LED, futhi iza nezindleko eziphakeme. Ngakho-ke, lapho uthenga isikrini se-LED, kubalulekile ukuthi ubheke izinto ezifana nendawo yokufaka kanye nohlobo lokuqukethwe okuzoboniswa ukukhulisa izindleko izindleko. Ngasikhathi sinye, gwema ukukhetha ukukhanya okukhulu ngokweqile ngaphandle kokuthi kudingekile ukuvikela izindleko ezingadingekile.
Cabanga ngemvelo yokufaka lapho ukhetha ukugqama kwesikrini se-LED
Imvamisa, ukugqama kwezikrini ze-Indoor LED kufanele zibe phakathi kwama-800 kuya kwangama-2500 nits, kuya ngamazinga okukhanya akhona wendawo yangaphakathi. Ezinye izindawo zasendlini zingahle zikhanyiswe kakhulu, kanti ezinye zingabonakala zikhanya ngenxa yokuhlunga kwelanga ngokusebenzisa izindonga zengilazi, amawindi, noma ezinye izakhiwo.
Ngezikrini zangaphandle ze-LED, izidingo zokukhanya ziyahlukahluka ngokuya ngendawo nesikhathi:
- Ezindaweni ezingaphandle okunomthunzi, ukugqama kwesikrini kwe-LED kufanele kusethwe phakathi kwama-2500 no-4000 Nits;
- Ezindaweni zangaphandle ngaphandle kokukhanya kwelanga okuqondile, ukugqama kwesikrini esifanelekile kuphakathi kwezingu-3500 no-5500 Nits;
- Ngokukhanya kwelanga okuqondile, ukugqama kwesikrini kwe-LED kudinga ukwedlula ama-nits angama-5500 ukuqinisekisa ukuthi imininingwane ibonakala kahle.
Kubalulekile ukuqaphela ukuthi la manani wokukhanya okukhazimula kuyizinkombandlela kuphela. Empeleni, ukukhanya okukhona ezindaweni ezahlukahlukene kungahluka kakhulu. Ngakho-ke, kungakuhle ukuthola ukugqama kwesikrini okuholwa kakhulu okuvela ekuhlolweni kwesayithi noma ekuhlolweni kwalawa mabanga aphakanyisiwe. Ngaphezu kwalokho, ukufuna izeluleko zochwepheshe ezivela kubahlinzeki besikrini abanolwazi be-LED noma abahlinzeki kungaba usizo.
Umthelela wesitayela sokuqukethwe ekukhazimuleni kwesikrini se-LED
Izinga lokukhanya okudingekayo kwesikrini se-LED lingahluka ngokuya ngohlobo lokuqukethwe okuboniswayo, ikakhulukazi kuzinhlelo zokusebenza zasendlini:
- Ngezikrini eziholwa ezibonisa imininingwane elula yombhalo, izinga lokukhanya kwama-nits angama-200 kuya kwangama-300 anele;
- Okokuqukethwe okujwayelekile kwevidiyo, ukukhanya kwesikrini kwe-LED kufanele kube phakathi kwama-400 kuya kwangama-600.
- Ukukhangisa, ikakhulukazi okuqukethwe kudinga ukudluliswa kwesicelo esibonakalayo sokubuka, ukugqama kwesikrini kwe-LED kukhuphuke kuya ku-600 kuye ku-1000 Nits.
Ukugcina
Sekukonke, ukugqama kuyisici esibalulekile ekuqinisekiseni ukucaciselwa kokuqukethwe kwesikrini se-LED, ukuthuthukisa ikhwalithi yesithombe, nokwakha umthelela obonakalayo. Izikrini ze-LED zinenzuzo enkulu ekukhazimuleni ngaphezu kobunye ubuchwepheshe bobukiso, ukuzenza zilungele izinhlelo eziningi zezicelo. Kodwa-ke, lapho ukhetha isikrini se-LED, kubalulekile ukucubungula izici ezahlukahlukene zokuqinisekisa ukuthi ukukhanya okukhethiwe kuhlangabezana nezidingo ezisebenzayo ngenkathi ulungiselela isilinganiso sokusebenza kwesikrini.
