Uma ubuka imuvi, uhlela izithombe, noma udlala igeyimu, ukukhanya okuzungezile kwesikrini sakho kushintsha buthule okubonayo. Amehlo akho ajwayelana nombala walokho kukhanya, futhi uma kunganembile, isikrini sakho ngeke sibukeke ngendlela okufanele sibukeke ngayo.

Imigqa eminingi ye-LED namalambu athengiswa njengokuthi “6500K” ayizilinganiso nje ezinzima. Angase abukeke amhlophe, kodwa ngokuvamile ancike kakhulu eluhlaza okwesibhakabhaka noma eluhlaza kakhulu. Lokho kushintsha okucashile kwenza amehlo akho abone i-TV yakho noma imibala yokuqapha ngokungalungile. Okumhlophe akubukeki kungathathi hlangothi, izithunzi zilahlekelwa imininingwane, futhi amathoni esikhumba ayanyakaza.

I-D65 ayilona nje izinga lokushisa lombala. Kuyindinganiso yasemini echazwe kahle esetshenziswa imboni yefilimu nokusakaza. Kuyisethenjwa esifanayo esisetshenziswa izikali zochwepheshe nezitudiyo ukuqinisekisa ukuthi wonke umbala kusikrini sakho ufana nenjongo yomdali. Uma ukukhanya kwakho kufana ne-D65, okubonayo yilokho abakubonile.

Siklama yonke i-LED ukuze ihambisane ne-D65 reference spectrum 95-99 CRI fidelity (kuya ngemodeli) futhi ukusebenza okungacwayizi. Kungakho ukukhanya kwe-MediaLight okuchemile kwethenjwa ama-studio, ama-calibrator, nabathandi emhlabeni wonke. Uma ukukhanya kwakho kulungile, isikrini sakho sibukeka silungile. Kulula kanjalo.

Imichilo ye-RGB yakhelwe kwemizwa, hhayi ukunemba. Ngenxa yokuthi basebenza kanjani, I-RGB ayikwazi nje ukukhiqiza okumhlophe kweqiniso. Ngokwencazelo, ama-LED abomvu, aluhlaza, naluhlaza nje axutshwa ukukhanya kuwo cishe It.

Ngisho nezinhlelo ze-“RGBW” azikuxazululi umkhawulo oyisisekelo. Zisasekelwe ekwakhiweni okufanayo okuhlanganisa okungeziwe kwe-RGB, okune-emitter emhlophe eyengeziwe ukuze kunwetshwe ububanzi obuguquguqukayo noma kukhulise ukukhanya. Izinhlobonhlobo ezifana ne-“RGBCW/WW” zikhona, kodwa zabelana ngesiphambeko esifanayo: ukusatshalaliswa kwamandla okubonwayo okungajwayelekile (SPD) okuneziqongo ezingapheli kanye nezikhala. Ngamanye amazwi, "okumhlophe" okukhishiwe kunokufana okuncane kwe-spectral nezikhanyisi ezijwayelekile ezifana ne-D65.

Abanye abantu bazama "ukushuna" ukukhanya kwabo okuchemile ukuze kufane nombala wabo odongeni - isibonelo, ukusebenzisa ukukhanya okufudumele ukuze basuse upende onethoni epholile. Kodwa lokho akudali ukungathathi hlangothi; ihlanganisa iphutha nje. Uma uhlanganisa imibala ehambisanayo, awubi mpunga - uba mnyama. Ngobuchwepheshe, lokho ukungabikho kokukhanya okubonisiwe. Ngakho-ke uma ubona ukukhanya, awuboni nhlobo okumpunga - ubona i-tint ezwa sengathi ingathathi hlangothi ngoba amehlo akho ajwayelene nayo. Udonga lungase lubukeke lulinganisele, kodwa manje igumbi lonke - okuhlanganisa isibonisi sakho - lisusiwe ku-eksisi. Izibonisi azilinganiswa umbala wodonga lwakho. Okuwukuphela kwendlela yokuhlala unembile ukuqala kunkomba eyaziwayo ye-D65 futhi unamathele kuyo.

Kufana noku-oda ukudla kwamaShayina endaweni yokudlela — ungathola okuthile okubizwa Inkukhu kaGeneral Tzo, kodwa cishe akufani nento yangempela. Bese futhi, Inkukhu kaGeneral Tzo akukaze kube yi-cuisine yamaShayina eyiqiniso ekuqaleni. Kulingisa ukulingisa — indalo ekhona kuphela ngoba othile okude nomthombo unqume ukulinganisa eyokuqala. Okufanayo kuya ku-RGB-based "white": iresiphi esungulwe ukulingisa into engakaze yakhelwe ukuthi iphinde ikhiqize.

Asilona uhlobo lwabantu abathi awukwazi ukuzijabulisa ngokusetha kwakho. Izingane ezincane ziyakuthanda ukubuka Frozen namalambu aluhlaza okwesibhakabhaka, futhi ngizovuma ukuthi ngibukele The Little Mermaid namadodakazi ami ngenkathi siveza amagagasi ophahleni. Ngisho nezibani ezishibhile ze-RGB zinokucisha—futhi yilokho okubalulekile. Okumangalisayo ngokukhanya okuhle ukuthi kusishintsha kanjani ngokuphelele isikhala. Uma isikrini sakho sizungezwe ukukhanya okungathathi hlangothi, okunembile, sizizwa silungile. Yonke into ibonakala ingokwemvelo, i-cinematic kakhudlwana, iphila kakhudlwana.

Uma kukhulunywa ngokukhanya okunembile kwe-D65, awukwazi ukukhohlisa. Kungakho yonke iMediaLight yakhiwe ngama-phosphor LED enziwe ngokwezifiso ukuze afane ne-D65. Awekho amagimmikhi, azikho izinqamuleli.

Uma ukukhanya kwendawo okuzungezile kunembile, isikrini sakho sibukeka ngendlela ebesihloselwe ngayo: silinganisele, singathathi hlangothi, futhi siyiqiniso empilweni.
