Kuyini ukukhanya kwesikrini se-LED?
Ukukhanya kwesikrini sesibonisi se-LED kubhekisela ekushubeni kokukhanya okukhishwa ama-LED angaphakathi (Light Emitting Diodes). Ngokuvamile, sisebenzisa i-cd/m² (i-candela imitha yesikwele) noma ama-nits njengamayunithi ukulinganisa ukukhanya kwesikrini se-LED. Ukwenyuka kwevelu yokukhanya kubonisa ukuthi isibonisi se-LED sikhipha ukukhanya okunamandla. Isibonelo, isikrini se-LED sangaphandle esinokukhanya okungu-10,000 sikhanya kakhulu kunesikrini se-LED sasendlini esinama-nits angu-800 kuphela.
Ukubaluleka Kokukhanya Kwesikrini Se-LED
Ukuzivumelanisa Nezindawo Ezihlukene
Ukukhanya kwesikrini se-LED kubalulekile ukuze uzivumelanise nezimo ezihlukahlukene. Ukukhetha izinga lokukhanya elilungile akuqinisekisi kuphela ukuvumelana nendawo ezungezile kodwa futhi kuthuthukisa ukusebenza kahle kwezomnotho kwesikrini se-LED.
Umthelela Ekusebenzeni Sekukonke
Ukukhanya kuthinta kakhulu ezinye izinkomba zokusebenza zesikrini se-LED, njengokugqama, ukumpunga, nokudlidliza kombala. Ukukhanya okunganele kuthinta ngokuqondile ukusebenza kwesikrini kulezi zindawo, okunquma kakhulu ikhwalithi iyonke yesibonisi se-LED.
I-engeli yokubuka engaguquki
Ukukhanya okuphezulu kuvumela ukucaca okungaguquguquki kwesithombe kuyo yonke i-engeli yokubuka ebanzi. Lokhu kusho ukuthi noma sibukwa ngama-engeli angewona amaphakathi, isikrini se-LED sokukhanya okuphezulu singaqinisekisa ukuboniswa kokuqukethwe okucacile, kuyilapho isikrini esinokukhanya okuphansi singase sizabalaze ukuze sigcine ukucaca kusukela emaphethelweni.
Uhla Olubanzi Lwezicelo
Izikrini ze-LED ezinokukhanya okuphezulu zinezinhlobonhlobo zezinhlelo zokusebenza, ezifanele izindawo ezifana nezitolo zezitolo, izikhumulo zezindiza, izindawo zezemidlalo, namahabhu okuthutha adinga ukubonakala okuphezulu nekhwalithi yesithombe. Ngokuphambene, izikrini ze-LED ezinokukhanya okuphansi ngokuvamile zikhawulelwe endaweni engaphakathi noma ekhanyayo.
Ungakunquma Kanjani Ukugqama Kwesikrini Se-LED Okufanele
Nakuba ukukhanya okuphezulu kuyinzuzo enkulu yezikrini ze-LED, futhi kuza nezindleko eziphezulu. Ngakho-ke, lapho uthenga isikrini se-LED, kubalulekile ukucabangela izici ezifana nendawo yokufaka kanye nohlobo lokuqukethwe okufanele kuboniswe ukuze kukhuliswe ukonga kwezindleko. Ngesikhathi esifanayo, gwema ukukhetha ukukhanya okuphezulu kakhulu ngaphandle uma kunesidingo ukuze uvimbele izindleko ezingadingekile.
Cabangela Imvelo Yokufaka Lapho Ukhetha Ukugqama Kwesikrini Se-LED
Ngokuvamile, ukukhanya kwezikrini ze-LED zasendlini kufanele kube phakathi kuka-800 no-2500 nits, kuye ngamaleveli okukhanya okuzungezile kwendawo yasendlini. Ezinye izindawo zasendlini zingase zibe nokukhanya kalufifi, kuyilapho ezinye zingase zibonakale zikhanya ngenxa yokukhanya kwelanga okusefa ezindongeni zengilazi, amafasitela, noma ezinye izakhiwo.
Kuzikrini ze-LED zangaphandle, izidingo zokukhanya ziyahlukahluka kuye ngendawo nesikhathi:
- Ezindaweni ezingaphandle ezinomthunzi, ukukhanya kwesikrini se-LED kufanele kusethwe phakathi kuka-2500 no-4000 nits;
- Ezindaweni ezingaphandle ngaphandle kwelanga eliqondile, ukukhanya kwesikrini se-LED okufanele kuphakathi kuka-3500 no-5500 nits;
- Elangeni eliqondile, ukukhanya kwesikrini se-LED kudinga ukudlula ama-nits angu-5500 ukuze kuqinisekiswe ukuthi ulwazi lubonakala ngokucacile.
Kubalulekile ukuqaphela ukuthi lawa manani okukhanya ayiziqondiso kuphela. Empeleni, ukukhanya kwe-ambient ezindaweni ezahlukene kungahluka kakhulu. Ngakho-ke, kuyatuseka ukucacisa ukukhanya kwesikrini se-LED okufanele kakhulu ngokuhlola okusendaweni noma ukuhlola ngaphakathi kwalezi zigaba eziphakanyisiwe. Ukwengeza, ukufuna iseluleko sochwepheshe kubaqhubi besikrini se-LED abanolwazi noma abahlinzeki kungaba yinzuzo.
Umthelela Wesitayela Sokuqukethwe Ekukhanyeni Kwesikrini Se-LED
Izinga lokukhanya elidingekayo lesikrini se-LED lingahluka kuye ngohlobo lokuqukethwe oluboniswayo, ikakhulukazi ezinhlelweni zokusebenza zasendlini:
- Ezikrinini ze-LED ezibonisa ulwazi lombhalo olula, izinga lokukhanya lama-nits angu-200 kuya kwangu-300 lanele;
- Ngokuqukethwe kwevidiyo evamile, ukukhanya kwesikrini se-LED kufanele kube phakathi kuka-400 no-600 nits;
- Ngokukhangisa, ikakhulukazi okuqukethwe okudinga ukukhanga okunamandla okubonakalayo, ukukhanya kwesikrini se-LED kufanele kunyuswe kube ngu-600 kuya ku-1000 nits.
Isiphetho
Sekukonke, ukukhanya kuyisici esibalulekile ekuqinisekiseni ukucaca kokuqukethwe kwesikrini se-LED, ukuthuthukisa ikhwalithi yesithombe, nokudala umthelela obonakalayo. Izikrini ze-LED zinenzuzo enkulu ekukhanyeni kunobunye ubuchwepheshe bokuboniswa, okuzenza zifanelekele uhla olubanzi lwezinhlelo zokusebenza. Kodwa-ke, lapho ukhetha isikrini se-LED, kubalulekile ukucabangela izici ezihlukahlukene ukuze uqinisekise ukuthi ukukhanya okukhethiwe kuhlangabezana nezidingo ezingokoqobo zohlelo lokusebenza kuyilapho kulungiselelwa isilinganiso sokusebenza nezindleko zesikrini se-LED.
