1. Isingeniso
Ngaphansi kwegagasi lenkathi yedijithali, isibonisi se-LED sesiyingxenye ebalulekile yokuphila kwethu, kusukela ebhodini lokukhangisa enxanxatheleni yezitolo kuya ku-smart TV ekhaya, bese kuya enkundleni yezemidlalo enkulu, inani lakhona likuyo yonke indawo. Nokho, ngenkathi ujabulela lezi zithombe ezikhazimulayo, ingabe wake wazibuza ukuthi yibuphi ubuchwepheshe obubenza imibala icace kangaka nezithombe zibe ngokoqobo? Namuhla, sizodalula ubuchwepheshe obubili obubalulekile kusibonisi se-LED: umehluko wombala nezinga lokushisa lombala.
2. Kuyini ukuchezuka kombala?
Ukushintshashintsha kwe-Chromatic kuzibonisi ze-LED kuyisici esibalulekile esithinta ukuzizwisa okubonakalayo. Empeleni, i-chromatic aberration isho umehluko phakathi kwemibala ehlukene eboniswa esikrinini. Njengoba nje ubungalindela ukuthi yonke imibala yomdwebo opendwe kahle imelelwe ngokunembile, kulindeleke okufanayo nasezibonisini ze-LED. Noma yikuphi ukuchezuka kombala kungathinta kakhulu ikhwalithi yesithombe sisonke.
Kunezici ezimbalwa ezinomthelela ekuphambukeni kombala kuma-LED, okuhlanganisa ukucekelwa phansi kwezinto ze-phosphor ezisetshenziswa kuma-chips e-LED, ukuhluka kwezinqubo zokukhiqiza, nemithelela yemvelo efana nezinga lokushisa nomswakama. Ngokuhamba kwesikhathi, lezi zici zingaholela ekushintsheni kwezinga lokushisa lombala kanye nokunikezwa kombala, okubangela imibala ebonisiwe ukuthi isuke kumibala ehlosiwe.
Ukuze kubhekwane nalezi zinselele, i-RTLED isebenzisa ubuchwepheshe obuthuthukisiwe bokulungisa iphuzu nephuzu. Le nqubo ihlanganisa ukulungisa kahle iphikseli ngayinye esikrinini ukuze kuqinisekiswe ukunemba kombala nokufana. Ake ucabange lokhu njengohlelo lokulungiswa kombala olwenziwe ngendlela oyifisayo ngobuhlalu belambu le-LED ngalinye, elilinganiswe ngokucophelela ukuze lisebenze ngokuvumelana. Umphumela uwukubonisa okubonakalayo okuhambisanayo nokugqamile, lapho iphikseli ngayinye inikela khona ekubonisweni okuhlangene nokunembile kwesithombe esihlosiwe.
Ngokusebenzisa ubuchwepheshe obunjalo obuyindida,I-RTLEDiqinisekisa ukuthi isibonisi ngasinye se-LED siletha idili elibonwayo langempela, ligcina ukwethembeka kombala futhi kuthuthukisa umuzwa wombukeli.
2.1 Isilinganiso kanye nenani lokungafani kombala
Umehluko wombala ulinganiswa kusetshenziswa amamethrikhi afana ne-Delta E (ΔE), ebala umehluko ocatshangelwayo phakathi kwemibala emibili. Izixhumanisi ze-Chrominance zinikeza ukumelwa kwezinombolo kwesikhala sombala futhi zenza kube lula ukulinganisa okunembile. Ukulinganisa okuvamile ngemishini yobungcweti kuqinisekisa ukuvela kabusha kombala okunembile ngokuhamba kwesikhathi futhi kugcina ikhwalithi yokubonisa.
2.2 Rarulula inkinga yakho yokungafani kombala wesikrini se-LED
Ukuze kuncishiswe ukuphuma kwe-chromatic, i-RTLED isebenzisa ama-algorithms okulinganisa athuthukile futhi isebenzisa izingxenye zekhwalithi ephezulu. Isixazululo sesofthiwe sivumela ukulungiswa kwesikhathi sangempela ukulungisa ukuchezuka nokugcina ukunemba kombala okungaguquki. Ukuphathwa kombala okuphumelelayo kuqinisekisa ukuthi izibonisi ze-LED zihlangabezana nezindinganiso zomkhakha kanye nokulindelwe ngamakhasimende, okuthuthukisa ukusebenza kokubukwayo ezinhlelweni ezihlukene.
3. Kuyini izinga lokushisa lombala?
Izinga lokushisa lombala liyipharamitha ebalulekile kuzibonisi ze-LED, echaza umbala wokukhanya okukhishwayo. Lo mqondo, olinganiswa ngo-Kelvin (K), usivumela ukuthi silungise ithoni yonke yesikrini nomkhathi. Isibonelo, izinga lokushisa lombala eliphakeme linikeza ithoni epholile eluhlaza okwesibhakabhaka, kanti izinga lokushisa eliphansi lombala linikeza ukukhanya okuphuzi okufudumele. Njengoba nje ukukhanya kwelanga kushintsha ekubeni phuzi ngokufudumele ebusika kuye kokubomvu okomlilo wedobo ehlobo, ukushintsha kwezinga lokushisa lombala kungavusa imizwelo nesimo sezulu esihlukahlukene.
Ukukhetha izinga lokushisa elilungile lombala kufana nokukhetha umculo ongemuva ophelele ozowubona. Kumamnyuziyamu, amazinga okushisa aphansi ombala athuthukisa ukukhanga komlando wemisebenzi yobuciko, kuyilapho emahhovisi, amazinga okushisa emibala aphezulu athuthukisa ukukhiqiza. Ubuchwepheshe bokuboniswa kwe-LED obuthuthukisiwe buvumela ukulungiswa kwezinga lokushisa kombala okunembayo, kuqinisekise ukuthi imibala ayigcini nje ngokunemba kodwa futhi ithinta imizwa nezethameli.
Izinto ezimbalwa ezithinta izinga lokushisa lombala kuzibonisi ze-LED, okuhlanganisa uhlobo lwe-phosphor esetshenzisiwe, idizayini ye-chip ye-LED, nenqubo yokukhiqiza. Ngokuvamile, ama-LED atholakala ngamazinga okushisa anemibala afana no-2700K, 3000K, 4000K, no-5000K. Isibonelo, i-3000K inikeza ukukhanya okuphuzi okufudumele, okwenza umuzwa wokufudumala nokunethezeka, kuyilapho i-6000K inikeza ukukhanya okumhlophe okupholile, okukhiqiza umoya omusha nokhanyayo.
Ngokusebenzisa ubuchwepheshe obuyindida bokulungisa izinga lokushisa lombala, ama-RTLED'sIzibonisi ze-LEDingakwazi ukuzivumelanisa nezimo ezihlukahlukene, iqinisekise ukuthi isethulo ngasinye esibukwayo siyidili langempela lamehlo. Kungakhathaliseki ukuthi ithuthukisa i-ambiance yomlando kumnyuziyamu noma ikhulisa ukusebenza kahle ehhovisi, ikhono le-RTLED lokushuna kahle izinga lokushisa lombala liqinisekisa ukuzizwisa okufanelekile kokubuka.
3.1 Ingabe izinga lokushisa lombala likuthinta kanjani ukubona kwethu?
Ukukhethwa nokulungiswa kwezinga lokushisa lombala kuhlobene ngokuqondile nokunethezeka kombukeli kanye neqiniso lesithombe. Uma ubuka ifilimu enkundleni yemidlalo yaseshashalazini, kungenzeka ukuthi uye waqaphela ukuthi izigcawu ezahlukene zihambisana nemibala ehlukene, edala izimo ezihlukene kanye nemizwa. Lokho umlingo wezinga lokushisa lombala. Ngokulungisa kahle izinga lokushisa lombala, isibonisi esiholayo singasilethela umuzwa wokubuka ogxile kakhulu.
3.2 Ukulungisa Izinga lokushisa Lombala Ezibonisini ze-LED
Isibonisi se-LED sivumela abasebenzisi ukuthi balungise izinga lokushisa lombala ngesilawuli se-RGB noma izilungiselelo zebhalansi emhlophe. Ukufanisa izinga lokushisa lombala nezimo zokukhanya ezizungezile noma izimfuneko ezithile zokuqukethwe kuthuthukisa ukunethezeka nokunemba kokubuka. Ukulinganisa okunembile kuqinisekisa ukusebenza kombala okungaguquki futhi kubalulekile ekugcineni ukwethembeka ezindaweni ezibaluleke kakhulu ngemibala njengezitudiyo zokuthwebula izithombe noma izindawo zokusakaza.
Ukulungisa izinga lokushisa lombala wesibonisi se-LED ngokuvamile kufinyelelwa ngenketho yezinga lokushisa lombala kumenyu yesibonisi noma iphaneli yokulawula, umsebenzisi angakhetha imodi yokushisa yombala ehlelwe ngaphambilini (njengombala ofudumele, umbala wemvelo, umbala opholile), noma alungise mathupha iziteshi ezibomvu, eziluhlaza, neziluhlaza okwesibhakabhaka ukuze kuzuzwe umphumela wethoni oyifunayo.
4. Isiphetho
Kunjani lokho? Le bhulogi yethula umqondo wezinga lokushisa lombala kanye nomehluko wombala kusibonisi se-LED, nendlela yokukulungisa. Uma ungathanda ukufunda okwengeziwe mayelana nezibonisi ze-LED, manjexhumana ne-RTLEDithimba lochwepheshe.
