1. Isingeniso
Ngaphansi kwegagasi le-Digital Age, Ukuboniswa kwe-LED sekuyingxenye ebaluleke kakhulu yezimpilo zethu, kusuka ku-Billboard ezitolo ezinkulu kuya kwi-Smart TV ekhaya, bese kuba nenkundla yezemidlalo ye-Grand Sports, kwayo yonke indawo. Kodwa-ke, ngenkathi uthokozela lezi zithombe ezinhle kakhulu, wake wazibuza ukuthi yini ubuchwepheshe obucacile futhi izithombe zibhekane namaqiniso kangaka? Namuhla, sizokwembula ubuchwepheshe obubili obubalulekile esibonisweni se-LED: Ukungafani kombala kanye nokushisa kombala.
2. Kukuphi ukuphambuka kombala?
Ukuhanjiswa kwe-chromatic embonisweni we-LED kuyisici esibalulekile esithinta umuzwa wokubuka. Empeleni, ukufutheka kwe-chromatic kubhekisele ekuqhekekeni phakathi kwemibala ehlukene kuboniswe esikrinini. Njengoba nje ubungalindela wonke umbala wobuciko obupendiwe ngokucophelela ukuze uvezwe ngokunembile, ukulindela okufanayo kusebenza ekubonisweni kwe-LED. Noma yikuphi ukuphambuka ngombala kungathinta kakhulu ikhwalithi yesithombe ephelele.
Kunezici eziningana zifaka isandla ekuphambukeni kombala kuma-LEDs, kufaka phakathi ukonakala kwezinto ze-phosphor ezisetshenziswe kuma-chip we-LED, ukuhlukahluka kwezinqubo zokukhiqiza, kanye namathonya ezemvelo afana nokushisa kanye nomswakama. Ngokuhamba kwesikhathi, lezi zinto zingaholela ekushintsheni kokushisa kombala nokuhunyushwa kombala, okwenza imibala ebonisiwe idonswe kusuka kuma-hues awo ahlosiwe.
Ukubhekana nalezi zinselelo, i-ruttled iqasha ubuchwepheshe bokulungiswa kwe-point-by-point. Le ndlela ifaka ukulungisa kahle i-pixel ngayinye esikrinini ukuze kuqinisekiswe ukunemba kwemibala kanye nokufana. Cabanga ngalokhu njengohlelo lokulungiswa kombala olwenzelwe ngokwezifiso ku-LED LAMP Bead ngayinye, lulinganiswe ngokucophelela ukusebenza ngokuvumelana. Umphumela uba umbukiso wokubukwa ohlanganayo futhi osebenzayo, lapho i-pixel ngayinye inomthelela ekuvezeni okuhlangene futhi okunembile kwesithombe esihlosiwe.
Ngokufaka ubuchwepheshe obunjalo obunobuhlakani obunjalo,I-RTYLEDIqinisekisa ukuthi yonke imihlahlandlela ye-LED ihambisa idili elibonakalayo leqiniso, eligcina ukwethembeka kombala kanye nokwenza ngcono isipiliyoni sombukeli.
2.1 Ukulinganiswa nokuncishiswa kokungafani kombala
Umehluko wombala uhlelwa usebenzisa amamethrikhi anjengeDelta E (ΔE), ebala umehluko ocatshangelwe phakathi kwemibala emibili. Izixhumanisi ze-Chrominiance zinikeza ukumelwa kwezinombolo zesikhala sombala kanye nokwenza lula ukulinganisa okunembile. Ukulinganisa okujwayelekile ngemishini yobuchwepheshe kuqinisekisa ukukhiqizwa kabusha kombala okunembile ngokuhamba kwesikhathi futhi kugcina ikhwalithi yokubonisa.
2.2 Xazulula inkinga yakho ye-LED Screen Colour Charepancy Inkinga
Ukuze unciphise ukuhanjiswa kwe-chromatic, i-ryled isebenzisa ama-algorithms athuthukile wokulinganisa futhi isebenzisa izingxenye ezisezingeni eliphakeme. Isixazululo sesoftware sivumela ukulungiswa kwesikhathi sangempela ukuze kulungiswe ukuphambuka nokugcina ukunemba kombala okungaguquki. Ukuphathwa kombala okusebenzayo kuqinisekisa ukuthi ama-LED ekhombisa ukufeza izindinganiso zezimboni kanye nokulindelwe kwamakhasimende, ukuthuthukisa ukusebenza okubonakalayo ezinhlelweni ezahlukahlukene.
3. Kuyini izinga lokushisa lemibala?
Ukushisa kombala kuyindlela ebucayi egqamile ekubonisweni kwe-LED, echaza i-hue yesibani esikhishwe. Lo mqondo, ulinganiswe eKelvin (K), usivumela ukuthi silungise ithoni nomoya onke. Isibonelo, izinga lokushisa eliphakeme lemibala lidlulisela ithoni eluhlaza okwesibhakabhaka eluhlaza okwesibhakabhaka, kanti izinga lokushisa lombala eliphansi linikeza ukukhanya okuphuzi okuphuzi. Njengoba ukukhanya kwelanga kuguquka kuphuzi olufudumele ebusika kuye obomvu ovuthayo ehlobo, izinguquko zokushisa umbala zingavusa imizwa ehlukene kanye nomoya.
Ukukhetha izinga lokushisa lemibala elifanele kufana nokukhetha umculo ophelele wangemuva wokuhlangenwe nakho okubonakalayo. Eminyuziyamu, amazinga okushisa aphansi umbala athuthukise ubuciko bomlando wezobuciko, ngenkathi emahhovisi, amazinga okushisa aphezulu akhulisa umkhiqizo. Ubuchwepheshe obuthuthukisiwe bokuboniswa kwe-LED bunika amandla ukulungiswa kombala okunembile, okuqinisekisa imibala akunangqondo kuphela kepha futhi kuhlanganisa imizwa nezilaleli.
Kunezici eziningana ezithinta izinga lokushisa lemibala ekubonisweni kwe-LED, kufaka phakathi uhlobo lwe-phosphor olusetshenzisiwe, ukwakheka kwe-chip ye-LED, kanye nenqubo yokukhiqiza. Imvamisa, ama-LED atholakala kumazinga okushisa anemibala afana ne-2700k, 3000k, 4000k, no-5000k. Isibonelo, i-3000K ihlinzeka ngokukhanya okuphuzi okuphuzi, ukudala umuzwa wokufudumala nenduduzo, kuyilapho u-6000k enikeza ukukhanya okumhlophe okupholile, kwakha umoya omusha futhi okhanyayo.
Ngokufaka ubuchwepheshe bokulungiswa kokulungiswa kombala okuyinkimbinkimbi, ama-rttled'sUkuboniswa kwe-LEDUngazivumelanisa nezimo ezahlukahlukene, ukuqinisekisa ukuthi isethulo ngasinye sokubuka siyidili langempela lamehlo. Noma ngabe kuthuthukisa i-ambiance yomlando emnyuziyamu noma ekwandiseni ukusebenza ehhovisi, amakhono e-RTYDER wokushisa kombala okuhle kuqinisekisa isipiliyoni sokubuka esifanele.
3.1 Ngabe izinga lokushisa lemibala lithinta kanjani isipiliyoni sethu sokubukwa?
Ukukhetha nokulungiswa kwamazinga okushisa umbala kuhlobene ngqo nenduduzo yombukeli kanye neqiniso lesithombe. Lapho ubuka i-movie enkundleni yemidlalo yeshashalazi, kungenzeka ukuthi ubonile ukuthi izigcawu ezahlukahlukene zihambisana nemibala ehlukene, eyakha imimoya ehlukene nemizwa ehlukile. Lowo ngumlingo wokushisa kombala. Ngokushintsha kahle izinga lokushisa kombala, ukubonisa okuholwa ku-LED kungasilethela okuhlangenwe nakho kokubuka okugxilile.
3.2 Ukulungisa izinga lokushisa kombala ekubonisweni kwe-LED
Ukuboniswa kwe-LED Vumela abasebenzisi ukuthi balungise izinga lokushisa lemibala ngokulawulwa kwe-RGB noma izilungiselelo ezilinganayo. Ukuqhathanisa izinga lokushisa kombala kuya ezimweni zokukhanyisa ezikhona noma izidingo ezithile zokuqukethwe kugcizelela induduzo nokunemba. Ukulinganisa okunembile kuqinisekisa ukusebenza kombala okungaguquki futhi kubalulekile ukuze ulondoloze ukuthembeka ezindaweni ezibucayi zombala njengezithombe zokuthwebula izithombe noma izikhungo zokusakaza.
Ukulungisa izinga lokushisa kombala kwesibonisi se-LED kuvame ukufinyelelwa ngenketho yokushisa yombala kumenyu yokubonisa noma iphaneli yokulawula, umsebenzisi angakhetha imodi yokushisa yombala esesethiwe (umbala wemvelo, umbala opholile), noma ulungise umbala opholile), noma ulungise kabusha Iziteshi ezibomvu, eziluhlaza, eziluhlaza okwesibhakabhaka ukufeza umphumela oyifunayo.
4. Isiphetho
Kunjani lokho? Le bhulogi yethula umqondo wokushisa kombala nomehluko wombala esibonisweni se-LED, nokuthi ungayilungisa kanjani. Uma ungathanda ukufunda kabanzi ngokuboniswa kwe-LED, manjeXhumana ne-RTYLEDiqembu labachwepheshe.
