Eminyakeni yamuva, izikrini ze-LED zithole ukuthandwa okukhulu, zithola indawo yazo hhayi kuphela ezinhlelweni zezohwebo kodwa nasekusetshenzisweni komuntu siqu. Asetshenziswa kuzilungiselelo ezahlukahlukene, kusukela kumakhonsathi nemicimbi yezinkampani ukuya emidlalweni yezemidlalo, imibukiso yezohwebo, nezitolo zezitolo. Kodwa-ke, intengo yazo ibanzi impela, isuka ku-$5,000 iye ku-$100,000 nangaphezulu, futhi izici ezithonya izindleko zabo zokugcina zihlukahlukene.
Omunye wemibuzo evame kakhulu abatshalizimali ababa nayo uma kukhulunywa ngawoIzikrini zokubonisa ze-LED uthi, “Ingabe izobiza? Ngingakwazi ukubuyisa izindleko futhi ngenze inzuzo?” Kulokhu okuthunyelwe kwebhulogi, sizocubungula izici ezinquma intengo yezikrini ze-LED nokuthi yini okufanele uyicabangele ngaphambi kokuthenga.
Izindleko Zokuboniswa Kwezindonga Ze-LED
Kunezici eziningi ezithonya intengo yezikrini zokubonisa ze-LED, futhi lezi zici zingahluka kuye ngomkhiqizi kanye nokucaciswa kwesikrini. Izinto ezibaluleke kakhulu zihlanganisa usayizi wesikrini, ukulungiswa, izinga lokuvuselela, ukuphakama kwe-pixel, nekhwalithi yama-LED asetshenzisiwe.
Usayizi Wesikrini Sokubonisa i-LED
Usayizi wesikrini sokubonisa i-LED ungenye yezinqumo ezibaluleke kakhulu zezindleko zaso. Ngokuvamile, izintengo zesikrini se-LED zibalwa imitha-skwele ngayinye, okusho ukuthi isikrini sikhulu, inani lentengo likhuphuka.
Ukukhetha isikrini se-LED sosayizi olungile kubalulekile ukuze uqinisekise ukuthi okuqukethwe kwakho kuyabonakala futhi kusebenza ngempumelelo. Izinto ezifana nebanga lokubuka, okuqukethwe nenjongo, kanye nesabelomali sakho, kuzoba nomthelela ekukhetheni kwakho usayizi wesikrini se-LED. Ngokucabangela lezi zici, ungenza isinqumo esihlakaniphile futhi ukhethe isikrini esizifanela kangcono izidingo zakho.
Ukulungiswa Kwesikrini se-LED
Ukulungiswa kubhekisela enanini lamaphikseli esikrinini. Ukulungiswa okuphezulu kusho amaphikseli engeziwe, okuholela ezithombeni ezibukhali. Ukukhetha ukulungiswa okulungile kubalulekile ukuze uqinisekise umuzwa obonakalayo wekhwalithi ephezulu.
Uma uhlela ukubeka isikrini ezindaweni lapho izibukeli zikude kakhulu, njengezinkundla zemidlalo noma izindawo zekhonsathi, into yokuqala okufanele icatshangelwe lapho ukhetha ukulungiswa kwesikrini ibanga lokubuka. Izinqumo eziphansi zingase zanele ezimweni ezinjalo. Kodwa-ke, uma ubeka isikrini endaweni encane njengegumbi lenkomfa noma isitolo sokudayisa, uzodinga isikrini esinokucaca okuphezulu ukuze uqinisekise ukucaca nemininingwane.
Isici sesibili okufanele sicatshangelwe uhlobo lokuqukethwe oluboniswa esikrinini. Uma uhlela ukukhombisa izithombe zekhwalithi ephezulu noma amavidiyo, isikrini sokucaca okuphezulu sizohlinzeka ngemininingwane edingekayo kanye nokucaca. Ngakolunye uhlangothi, uma ubonisa umbhalo olula noma izithombe, isikrini esinokulungiswa okuphansi singase sanele.
Isilinganiso sokuvuselela isikrini se-LED
Izinga lokuvuselela libonisa ukuthi izikhathi ezingakiUdonga lwe-LED ibuyekeza isithombe esibonisiwe ngomzuzwana ngamunye, silinganiswa nge-Hertz (Hz). Isibonelo, isilinganiso sokuvuselela esingu-60Hz sisho ukuthi isithombe sibuyekezwa izikhathi ezingama-60 ngomzuzwana. Izinga lokuvuselela eliphezulu liphumela ekunyakazeni okushelelayo odongeni lwe-LED.
Izinga lokuvuselela elidingekayo lodonga lwe-LED lincike ekusebenzeni kwalo. Ngezinjongo eziningi ezifana nemicimbi yebhizinisi, imibukiso yezohwebo, nezifundo, izinga lokuvuselela elingu-1920Hz lanele. Nokho, uma usebenzisa udonga lwe-LED ukuze ubuke okuqukethwe okuhamba ngokushesha njengezemidlalo noma amakhonsathi,I-Xr ebonakalayo amahlumela, uzodinga izinga eliphezulu lokuvuselela, ngokuvamile elinconyiwe ku-120Hz noma ngaphezulu. Lokhu kuqinisekisa ukuthi ukunyakaza kubonakala kushelela futhi kungenayo i-artifact ebonakalayo.
Ikhwalithi yama-LED Chips, ICs, Power Supplies, namaKhabhinethi
Ama-chips e-LED ayingxenye ebalulekile yezikrini zokubonisa ze-LED, ezinquma ukukhanya kwazo, ukunemba kombala, neminyaka yokuphila. Izikrini ze-LED ezinama-chips ekhwalithi ephezulu zivame ukubonisa ukukhanya okungcono, ukunemba kombala, nokuphila okude, kodwa futhi ziza ngentengo ephezulu. Usayizi nenombolo yama-chips kuzophinde kuthinte izindleko zesikrini, ngama-chips amakhulu nama-chips engeziwe anikela ezindlekweni eziphakeme. Ukwengeza, ikhwalithi yamasekhethi ahlanganisiwe (ama-IC) nezinto zikagesi zidlala indima ebalulekile ekuzinzeni nasekusebenzeni kahle kwesikrini sokubonisa se-LED. Ama-IC wekhwalithi ephezulu nezinto ezinikezwa amandla zithuthukisa ukuzinza kodwa zingase zenyuse izindleko zesikrini. Ngokuphambene, ama-IC wekhwalithi ephansi nezinto ezinikezwa amandla zingaholela ekuhlulekeni kwesikrini noma ukungasebenzi kahle, okuholela ezindlekweni eziphakeme zokukhanda noma zokushintshwa.
Amakhebula namaKhabhinethi
Izinga lezintambo lithinta ukuzinza kokudluliswa kwesignali, kuyilapho amakhabethe ahlinzeka ngokuvikeleka kwesikrini se-LED. Amakhebuli namakhabethe ekhwalithi ephezulu avamise ukukhuphula intengo yesibonisi sesikrini se-LED kodwa futhi aqinisekise ukuzinza kwaso nokuphila isikhathi eside.
Izindleko Zokuthumela kanye Nezindleko Zokupakisha
Usayizi nesisindo sezikrini zokubonisa ze-LED kuzothonya izindleko zokuthumela. Ukukhethwa kwendlela yokuthumela, ibanga eliphakathi kwendawo okuvela kuyo nendawo oya kuyo, kanye nohlobo lwempahla yokupakisha konke kunendima ekunqumeni izindleko zokuthumela. Izinto zokuthutha olwandle ngokuvamile zibiza kakhulu kunezokuthutha zasemoyeni, ikakhulukazi lapho zithutha inqwaba yezimpahla. Ukwengeza, ukukhethwa kwezinto zokupakisha kuthinta izindleko zokupakisha. Amakhreyithi okhuni ahlala isikhathi eside kodwa ayabiza, amabhokisi ekhadibhodi ayasebenziseka kalula kodwa awahlali isikhathi eside, futhi amakhreyithi okuthutha ngendiza anomsebenzi kodwa ayabiza. Kunconywa ukuthi ucabangele lezi zici ngokucophelela ngaphambi kokuthenga, njengoba zizokusiza ukuthi unqume izinketho ezingcono kakhulu zezidingo zakho.
Ngaphambi kokuthenga isikrini sokubonisa se-LED, qiniseka ukuthi uyaziqonda lezi zici futhi wenze izinqumo ezinolwazi ngokusekelwe kuzimfuneko zakho nesabelomali. Ukwengeza, kuwumkhuba omuhle uku-oda amasampula ukuze uqinisekise ikhwalithi noma usebenzise izinsiza ze-courier njenge-DHL, i-UPS, i-FedEx, noma ezinye lapho uthenga izisekeli ezingasindi njengezintambo, amakhadi e-IC, nezinto zikagesi. Le ndlela ithuthukisa ukunethezeka nokusebenza kahle kokuhlangenwe nakho kwakho kokuthenga. Ukutshala imali ku-LIsikrini sokubonisa se-EDkuyisinqumo esibalulekile, ngakho-ke ukucabangela ngokucophelela zonke lezi zici kubalulekile ekuthengeni okuyimpumelelo.
