Kungani Amasonto Engeziwe EfakaI-LED Video Wall?
Kule minyaka engamashumi amabili edlule, amasonto abehlanganyela ekukhulekeleni ngokwengeza izinto ezibonakalayo phakathi nezinkonzo.Uma sekugxile kakhulu ekuthululeni amehlo ehubo sekuyinsakavukela umchilo wesidwaba ukuthi okuqukethwe okufakwe odongeni kubheke phezulu.
Muva nje, amasonto amaningi anqume ukuqhubekela phambili nalesi sinyathelo ngokufaka izindonga zevidiyo ezinama-lead ezindaweni zawo ezingcwele.Lezi zibonisi zezindonga zevidiyo zivumela abaholi besonto ukuthi babelane ngamavidiyo enziwe ngokwezifiso, izithombe kanye nombhalo (njengamazwi okukhulekela noma umbhalo), kanye nokunye okuqukethwe.
Isizathu #1 - Sinengqondo Kakhulu
Izindleko ze- udonga lwevidiyo oluholelekile kwehla kakhulu ngezindleko zangaphambili kuphela ngo-15-20% ngaphezulu kokuqagela.Ngaphezu kwalokho, lapho isibani seprojektha noma yonke iprojektha ihluleka, izindleko zokushintshwa zingaba izinkulungwane zamaRandi isikhathi ngasinye.
Amaphaneli odonga lwevidiyo ayi-modular, ngakho iphaneli noma isibani singashintshwa ngenani eliphansi kakhulu.Umphumela uba ukuthi iphoyinti le-break-even ku-projection enamaledi kuthatha unyaka owodwa kuya kwemibili kuphela.
Ebhodini lodonga eliholwa yi-hd, umugqa wokuhlukanisa izindleko ungamayintshi angu-110.Ngodonga lwevidiyo lwamayintshi angu-110, intengo yodonga lwevidiyo ekhonjiwe iqhathaniswa nesibonisi se-lcd.Futhi kunoma yiluphi udonga lwevidiyo olukhulu kuno-180 amayintshi, intengo yevidiyo yephaneli yodonga eholwayo ingcono nakanjani kunanoma ibuphi obunye ubuchwepheshe bokubonisa obumile.
Isizathu sesi-2 - Ukusetshenziswa Kagesi Okuphansi
Isamba sezindleko ze-engeli yobunikazi kusukela kumpilo yesistimu, udonga oluholwa isibonisi luphakeme kune-projektha nezibonisi ze-lcd futhi lunegalelo ekutshalweni kwezimali okuhlakaniphile kwebandla.
Okokugcina, ama-led adla amandla angaphansi kuka-40-50% kunamaphrojektha.Naphezu kwalokhu, zingaphinde zikhiphe amanani abalulekile okushisa.
Lapho ukhetha isistimu yokuqagela, ngokuvamile uzogxila ezindlekweni ezingaphambili.Nokho, amasonto amaningi achitha izinkulungwane zamaRandi ngenyanga ethenga ugesi.Ukonga okukhulu kutholwa inyanga ngayinye ngo-isibonisi sevidiyo esiholayoisikrini singabuyiselwa ngokuqondile kusabelomali sebandla lakini.
Isizathu #3 – Ngokugqama Okuphezulu kanye Nesilinganiso Sokugqama Okuphakeme
Ukuqagela okuvamile kungase kuntule ukukhanya ukuze ufundeke kalula futhi uhlanganyele esikhaleni sakho. Nakuba ukukhanya kwe-projection ngokuvamile kunqunywa i-lux (ukukhanya okuveziwe noma okubonisiwe), ukukhanya kweledi, okukalwa ngama-nits, ubukhulu bokukhanya okusuka ngqo ku-diode ezikhiphayo.I-Nits eyodwa ilingana ne-3.426 lux.
Ngenkathi ukufakwa kahle kuqala kuma-lumens angu-300 ngokukhanya kwe-modular video wall, kungahamba futhi kuze kufike ku-800 nits, ngakho-ke akudingi igumbi elimnyama futhi kusebenza kahle ezinhlelweni zokusebenza ngisho nangaphansi kwezimo zokukhanya ezizungezile.
Uma indawo yakho yokukhulekela inokukhanya okuzungezile ngezikhathi ezithile zosuku, udonga lwevidiyo yesonto olune-led lungaba yisixazululo esihle kakhulu.Ungathuthukisa ukugqama ngokukhuphula izinga elimnyama lengemuva noma ngokwandisa ukugqama kwabamhlophe, ividiyo eholayo. izindonga zingakwenza kokubili.
Udonga lwevidiyo lunokukhanya okuphezulu kunomklamo, ngakho okumhlophe kuyagqama, kanye nesikrini sodonga esiholwa yividiyo ngokwaso simnyama ngoba sisebenzisa amaledi amnyama, kuyilapho i-projection ingokwemvelo enengemuva elimhlophe.
Ngokuvamile, udonga lokubonisa olunephimbo elihle lungaba nesilinganiso sokungafani esingu-6000:1 uma kuqhathaniswa no-2000:1 kuprojektha.Esinye isibalo esiyinhloko yi-grayscale ezimeni zokukhanya okuphansi.Izindonga ze-LED manje zingakwazi ukuphatha ukujula kombala we-16-bit futhi zigcine amazinga aphezulu ampunga ngaphandle kokwehlisa ikhwalithi yesithombe ngisho nasezimeni eziphansi zokukhanya.
Izithombe ezihlongozwayo, uma zingaphansi kwezimo zokukhanya okuphansi, zingafiphalisa noma zibonakale zigezeke lapho isibani sishiswe kakhulu.Ebandleni lakini, bangafunda amazwi, imibhalo, futhi bajabulele kangcono izithombe ngazoizindonga zevidiyo zesonto.
Isizathu #4 - Isikhathi Sokuphila Eside I-TV Wall
Izindonga ze-LEDube nesikhathi sokuphila esibekwe kabili noma kathathu kunesibikezelo.Amaphrojektha ngokuvamile anesikhathi sokuphila seminyaka emi-3 - 5, futhi ubude bempilo bawo ngokuvamile budingeka ukuze kushintshwe ama-bulb ezikhathi ezithile nezinjini zokukhanyisa.
Izindonga zevidiyo yesonto le-LED zinesikhathi sokuphila samahora angu-100,000 noma iminyaka engu-11.5.Lokhu kungenxa yokuthi iprojektha inomthombo owodwa wokukhanyisa, okusho ukuthi inesibani esisodwa sako konke ukukhanya komfanekiso.
Nakuba izindonga zesikrini sevidiyo zinezigidi zemithombo yokukhanya evela ku-luminescence, ukufana kwazo kushisa ngesivinini esifana neyunifomu.
Ngenxa yalezi zizathu ezi-4 ezingenhla, ayanda amasonto afaka izindonga zevidiyo esikhundleni sama-projektha angaphambilini.Eyethuizibonisi ezilungisiwe zasendlinibaye bathandwa amasonto amaningi, ikakhulukazi i-p2.5 eshibhile eholwa udonga , ethatha cishe u-60% wokukhiqiza ngenxa yokufaka nokulungisa kalula, amanani okuncintisana nemiphumela ephelele.uma unombono, ngicela ungithinte.
