Ngaphambi kweprojektha, i-slide yayisetshenziswa njengomkhiqizo ovelele embonini, futhi yayibonwa njengendlela ekhethekile ye-projektha. Ukubonakala komshini wama-slide kuhlehlela emuva ku-1640 AD, ngaleso sikhathi, umpristi ongumJesuit wasungula isilayidi esibizwa ngokuthi umlingo. Isibani, usebenzisa i-lens nesibuko sibonakalisa isimiso sokukhanya, uchungechunge lwezithombe eziboniswa odongeni, lwabangela ukuzwa, kodwa kungenxa yokusungulwa, wamangalelwa ngomlingo, wakhanga ukubulala, futhi wathunyelwa ku-"guillotine".
Nokho, ukufa kukaChiser akuzange kuphazamise ukuphishekela ubuchwepheshe obusha,kanye ne-German Jewish Kischal yachaza okokuqala ukusungulwa komshini wama-slide ngo-1645. Igobolondo lokuqala le-slide liyinsimbi ebhokisini eliyisikwele, phezulu kwesilinda sokukhipha intuthu esifana nesilinda, phambi kwesilinda, isilinda esine- Ilensi ye-convex eshelelayo, yakha ilensi elula, kukhona iphaneli lebanga eliguquguqukayo lokugxila phakathi kwelensi nebhokisi lensimbi, ibhokisi liqukethe umthombo wokukhanya, umthombo wokukhanya wangempela ukukhanya kwekhandlela.Uma usebenzisa, umshini wama-slide ufakwa ekamelweni elimnyama , isilayidi singene endaweni engemuva kwelensi eyi-convex, sikhanyise ikhandlela, umthombo wokukhanya ngokusebenzisa ukuhlangana kwesibuko esibukweni, ngesithombe esikhanyelayo nelensi, yakha ikholomu yokukhanya ebonakala esikrinini sodonga.
Ngo-1845, ngokudlondlobala kweNguquko yezimboni, imishini yama-slide nayo yangena enkathini yokukhiqizwa kwezimboni, imithombo yokukhanya nayo yashintsha isuka emakhandleleni yangaphambili yaba izibani zikawoyela, izibani zesimusi, futhi ekugcineni yaqala ukusetshenziswa kwemithombo yokukhanya kagesi.
Amaslayidi okuqala enziwe ngengilazi, ngokudweba ngezandla, futhi maphakathi nekhulu le-19, ngemva kokuba abaseMelika besungule ifilimu ye-celluloid, ama-slides akhiqizwa kusetshenziswa i-shift yezithombe. Kamuva, umshini wokudlala, esasiwusebenzisa kakhulu, wathuthukiswa futhi wathuthukiswa ngesisekelo somshini wama-slide wekhulu le-19.
Ngemva kweMpi Yezwe II, ukusungulwa kwamakhompiyutha, ukuvela okukhulu kwamasekhethi ahlanganisiwe kanye nokusungulwa kanye nokusetshenziswa okubanzi kobuchwepheshe obusha kwaletha iprojektha enkathini yedijithali.Iprojektha yokuqala isebenzisa ubuchwepheshe be-CRT, izibonisi zakuqala namasethi we-TV ubuchwepheshe be-CRT. ,isici sabo esiyinhloko ubukhulu obukhulu.Kamuva, kwavela ubuchwepheshe be-LCD, nokuthuthukiswa kobuchwepheshe be-LCD nakho kwenza i-CRT yaqala ukuba umlando.
Ngo-1968, u-GHHeilmeier, usosayensi wase-US e-RCA Corporation, wenza i-crystal ewuketshezi yaba i-LCD ngokuvumelana nomphumela wokuhlakazeka oshukumisayo, wenza i-prototype yemboni ye-LCD, kodwa ayizange ithengise ubuchwepheshe. kuthuthukiswe izibali namawashi ngobuchwepheshe be-LCD njengephaneli yokubonisa, futhi kwaholela abakhiqizi abaningi abafana no-Hitachi, NEC kanye no-Toshiba ukuthi bajoyine amazinga okuthuthukiswa komkhiqizo we-LCD nokukhiqiza.
Kusetshenziswe ubuchwepheshe be-LCD kudivayisi ye-projection i-Epson, esebenzisa ikristalu ewuketshezi ukuze iguqule ilungiselelo ngaphansi kwesenzo sama-electrode ukuze umthombo wokukhanya usebenzisa i-LCD chip ukwazi ukukhiqiza izithombe nge-lens.Nakuba kuwubuchwepheshe bakamuva bangaleso sikhathi, iprojektha ye-LCD yayisenokukhubazeka kokusebenza kanye nombala okusekelwe esakhiweni se-monolithic, nakho kokubili izinga lokuvula eliphansi kakhulu nesixazululo. Kwaze kwafika ngo-1995 lapho ama-projektha e-LCD anocezu olulodwa afakwa ngokusemthethweni emakethe, alandelwa obunye ubuchwepheshe be-3LCD ngo-1996. ngentuthuko ekuzinzeni nasekusebenzeni kombala.I-Sony yajoyina ukuthuthukisa ama-LCD chips, kodwa yamemezela ngo-2004 ukuthi izoyeka ukunikeza ama-chips e-LCD ukuze isetshenziswe ngaphakathi kuphela.Kuze kube manje, ubuchwepheshe be-LCD bokubukeka buphethwe yi-Epson kanye ne-Sony.
Ngo-1987, uDkt. Larry Hornbeck wasungula idivayisi yokuqala ye-DMD.Ngo-1996, ubuchwepheshe be-data optical processing be-DLP babuthengiswa ngokusemthethweni emakethe yokubonisa i-projection, kanye ne-DLP projektha yokuqala yethulwa, ngemva kweminyaka eyisikhombisa kuphela iprojektha ye-LCD.
I-chip yasekuqaleni ye-DLP yayine-prototype resolution engu-16*16, kuyilapho iprojektha yokuqala ye-DLP yayine-lumens engu-300 kuphela, okusho ukuthi yayingabonwa kuphela ezindaweni ezimnyama. Noma kunjalo, amasu amabili ahlukene emakethe obuchwepheshe be-DLP adlale indima enhle ekuqondiseni. ukuthuthukiswa kwayo kobuchwepheshe, futhi yangena ngokushesha emakethe, iletha ingcindezi enkulu kubuchwepheshe bokuqagela kwe-LCD.
Iprojektha ye-DLP emakethe yakuqala ngale nzuzo, kusukela ngo-1997 inesisindo esingamakhilogremu angu-6 kuphela i-InFocus LP420 kuya ku-2005 iprojektha ephaketheni ye-Samsung, iprojektha ye-DLP iyaqhubeka nokwethula ukuvuselela okusha komqondo "okuphathekayo", yashanela imakethe yebhizinisi ngesidingo esilangazela seselula, ngaleyo ndlela izuza. imakethe, futhi ngo-2006 emakethe yomhlaba wonke yazuza isabelo semakethe esingamaphesenti angu-20, ngobuchwepheshe be-LCD. Ngaphezu kwalokho, iprojektha ye-DLP eneziqephu ezintathu yasetshenziswa kumaphrojekthi aphezulu wobunjiniyela namasinema, akha izikhala zobuchwepheshe. ngokulungiswa okuphezulu kanye nokuzinza okuphezulu amaphrojetha e-LCD angeke akwazi ukukuxazulula esikhathini esidlule.
Nakuba ubuchwepheshe be-DLP buthuthuke kakhulu, ubuchwepheshe be-LCD buyalawuleka kakhulu ku-supply chain, izindleko, uma kuqhathaniswa ne-DLP, nobunye ubuchwepheshe obuthuthuke kakhulu, izindleko ziyalawuleka, ukusebenza okuzinzile, ububanzi bokusebenza, ikakhulukazi ngemva kobhubhane. era, izoba kabanzi impahla yabathengi be-elekthronikhi ethandwa kakhulu esikhathini esithile.
