Pamberi pepurojekita, masiraidhi aishandiswa sechigadzirwa chikuru muindastiri, uye aionekwa semhando yepurojekita. rambi, kushandisa lens uye girazi kuratidza chiedza musimboti, nhevedzano yemifananidzo yakaratidzwa pamadziro, yakakonzera manzwiro, asi imhaka yezvakagadzirwa, akapomerwa zvemashiripiti, akakwezva mhondi, uye akatumirwa ku "guillotine".
Kufa kwaChiser, zvisinei, hakuna kukanganisa kutsvaga tekinoroji nyowani,uye German Jewish Kischal yakatanga kutsanangura kugadzirwa kwemasiraidhi muna 1645. Goko rekutanga resiraidhi isimbi mubhokisi mativi mana, pamusoro peutsi inobudisa humburu yakafanana necylinder, pamberi pehumburumbira, silinda ine inotsvedza convex lens, gadzira lens iri nyore, pane pani yeinogadziriswa yakatarisa kureba pakati pelens nebhokisi resimbi, bhokisi rine mwenje sosi, yekutanga mwenje sosi mwenje mwenje. Kana uchishandisa, siraidhi muchina unoiswa mukamuri dema. , slide ichipinda muslot kuseri kweconvex lens, yakabatidza kenduru, mwenje sosi kuburikidza negirazi rekuratidzira convergence, kuburikidza neyakajeka mufananidzo uye lens, gadzira mwenje mbiru inoratidzwa pamadziro skrini.
Muna 1845, nekukura kweChimurenga cheindasitiri, masiraidhi makina akapindawo munguva yekugadzirwa kwemaindasitiri, zvitubu zvemwenje zvakachinjawo kubva kumakenduru apfuura kuenda kumarambi emafuta, marambi echipfunga, uye pakupedzisira akatanga kushandiswa kwemagetsi emagetsi.
Masiraidhi epakutanga-tanga akagadzirwa negirazi, nependi yemaoko, uye pakati pezana remakore rechi19, mushure mekunge vanhu vekuAmerica vagadzira firimu recelluloid, masiraidhi akagadzirwa pachishandiswa mafoto shift. pahwaro hwezana ramakore rechi 19 muchina wemasiraidhi.
Mushure meHondo Yenyika II, kugadzirwa kwemakomputa, kubuda kukuru kwemaseketi akabatanidzwa uye kugadzirwa uye kushandiswa kwakawanda kwemichina mitsva kwakaunza purojekita munguva yedhijitari. Iyo yekutanga purojekita inoshandisa tekinoroji yeCRT, yekutanga kuratidzwa uye seti yeTV tekinoroji yeCRT. ,chinhu chazvo chikuru kukura kukuru.Gare gare, teknolojia yeLCD yakaonekwa, uye kugadzirwa kweLCD teknolojia yakaitawo CRT yakatanga kuva nhoroondo.
Muna 1968, GHHeilmeier, nyanzvi yesainzi yekuUS kuRCA Corporation, yakagadzira kristaro yemvura kuita LCD zvinoenderana neiyo simba yekuparadzira mhedzisiro, ichiita prototype yeindasitiri yeLCD, asi haina kumbobvira yatengesa tekinoroji. yakagadzira macalculator nemawachi ane LCD tekinoroji sedhizaini yekuratidzira, uye yakatungamira vagadziri vazhinji vakaita saHitachi, NEC naToshiba kuti vabatane neLCD kugadzirwa kwechigadzirwa uye mazinga ekugadzira.
Yakaisa tekinoroji yeLCD kune mudziyo wekufungidzira iEpson, inoshandisa iyo crystal yemvura kushandura marongero pasi pechiito chemagetsi kuitira kuti sosi yemwenje kuburikidza neLCD chip inogona kugadzira mifananidzo kuburikidza nelenzi.Kunyangwe iri tekinoroji yazvino yenguva iyoyo, LCD projector ichiri kuita uye kukanganiswa kwemavara kwakavakirwa pachimiro chemonolithic, iine ese ari maviri akanyanya kuderera kuvhura mwero uye resolution. Yakanga isati yasvika 1995 iyo imwe-chimedu LCD mapurojekita akaiswa zviri pamutemo mumusika, ichiteverwa neimwe 3LCD tekinoroji muna 1996. nekubudirira mukugadzikana uye kuita kweruvara.Sony yakabatana nekugadzira maLCD machipisi, asi yakazivisa muna 2004 kuti yaizomira kupa maLCD machipisi ayo ekushandisa mukati chete.Kusvika parizvino, tekinoroji yeLCD inodzorwa neEpson neSony.
Muna 1987, Dr. Larry Hornbeck vakagadzira yekutanga DMD mudziyo.Pakazosvika 1996, data optical processing DLP tekinoroji yakatengeswa zviri pamutemo kumusika wekuratidzira, uye yekutanga DLP purojekita yakatangwa, makore manomwe chete mushure meLCD projekita.
Iyo yekutanga DLP chip yaive neprototype resolution ye16*16, nepo yekutanga DLP projekita yaingova ne300 lumens, zvichireva kuti yaingoonekwa munzvimbo dzine rima.Zvisinei, nzira mbiri dzemusika dzakasiyana dzeDLP tekinoroji dzakaita basa rakanaka mukutungamirira. kuvandudza kwayo tekinoroji, uye nekukurumidza kutora pamusika, zvichiunza kumanikidza kwakawanda kuLCD projection tekinoroji.
DLP purojekita mumusika wekutanga nemukana uyu, kubva 1997 inorema 6 pondo InFocus LP420 kusvika 2005 Samsung's pocket projector, DLP purojekita inoenderera mberi nekutanga kuzorodza pfungwa ye "inotakurika", yakatsvaira musika webhizinesi nechido chekuda mbozhanhare, nekudaro kuwana. kutsika mumusika, uye muna 2006 mumusika wepasi rose wakahwina pamusoro pe20% musika wekugovanisa, neLCD tekinoroji.Mukuwedzera, matatu-chidimbu DLP purojekita akaiswa kune yakakwirira-yekupedzisira engineering uye cinema mapurojekiti, achigadzira mapeji ehunyanzvi. mukugadziriswa kwepamusoro uye kugadzikana kwepamusoro izvo LCD mapurojekita haagone kugadzirisa munguva yakapfuura.
Kunyangwe tekinoroji yeDLP ichinyanya kufambira mberi, tekinoroji yeLCD inonyanya kudzoreka mucheni yekugovera, mutengo, uchienzaniswa neDLP, uye imwe tekinoroji yepamusoro, mutengo unodzoreka, kuita kwakadzikama, chiyero chekushandisa, kunyanya mushure medenda. era, ichave yakawedzera kuve yakakurumbira zvinhu zvemagetsi zvevatengi mune imwe nguva.
