Iprojektha yayisisixhobo esasetyenziswa ngabantu abambalwa, ngenxa yeendleko kunye neendawo ezibaluleke kakhulu ezifunekayo, kodwa ngoku iiprojekti zanamhlanje ziye zawathoba kakhulu amaxabiso kwaye, ngenxa yesi sizathu, zinokusetyenziswa endaweni kamabonwakude kwimisebenzi emininzi. Abantu abaninzi bakhetha iprojekti endaweni yomabonwakude oqhelekileyo ukuze banandiphe i-cinema, ekubeni izikrini zikhulu, ukuya kwi-intshi ezingama-20. Iprojektha ikuvumela ukuba ujonge inkcazo ephezulu okanye umxholo wenkcazo ephezulu.
Oku kuya kufuna ukuba igumbi lonke liphelele: kunokwenzeka ukuba ufumane igumbi endlwini ongayazi ukuba lisetyenziswe njani kwaye iprojektha ngale ndlela inokuba yeyona ndlela ichanekileyo.
Ukukhetha iprojekti efanelekileyo kakhulu kwiimfuno zakho, kufuneka uqale uqonde umahluko phakathi kobuchwepheshe obuphambili bokusebenza kweeprojekti zevidiyo: i-LCD (i-Liquid Crystal Display) kunye ne-DLP (i-Digital Light Processing). Apha ungafumana uthelekiso olukhethekileyo.
Eyangaphambili isekelwe kwiprism ye-cubic eyenziwe ngobuso obuthathu apho iipaneli ze-LCD zifakwe khona. Ubuso ngamnye bunepaneli, enye eluhlaza, enye eluhlaza okwesibhakabhaka, kunye nebomvu enye.
Iiprojektha zeteknoloji ye-DLP, kwelinye icala, ziqulethe i-optical chip ebizwa ngokuba yi-DMD kwaye yenziwe ngezipili ezincinci okanye iipikseli. Njengoko i-oscillate, izibuko ezincinci zibonisa ukukhanya okukhutshwa sisibane seprojekti, esongezwa kwi-beam eyongezelelweyo yokukhanya ekhutshwe yi-chip ye-DMD. Ekugqibeleni, ivili lombala eliphakathi kwe-DMD kunye nelensi, elijikeleza ngesantya esiphezulu, lifaka imibala ngokufanelekileyo kumfanekiso ukuze ubonakale ngokuchanekileyo.
Isigqibo
Ngokuxhomekeke kwindlela oyisebenzisa ngayo, vavanya uhlobo lwesisombululo seprojektha. Unokukhetha kwizisombululo ze-SVGA zakudala ezingama-800 x 600 pixels, ezifumaneka kwiiprojektha zesizukulwana esidala.
Akhanye
Ukukhanya yenye yezona zinto zibalulekileyo njengoko ichaza amandla okukhanya ukuba iprojekti idlulisela kwisikrini. Eli xabiso lilinganiswa nge-ANSI Lumen, apho enye ilingana nokukhanya okukhutshwa likhandlela.
Ukuba ukukhanya kweprojekti kuphezulu, isixhobo siya kukwazi ukuhambisa imifanekiso ebonakalayo nakwiindawo ezingekho mnyama ngokupheleleyo.
Umahluko okhoyo
Umlinganiselo wokuthelekisa ubonisa ukukwazi kwesixhobo ukunika zombini iindawo ezimnyama nezikhanyayo, kungakhathaliseki iimeko zokukhanya.
ukulungiswa kwelitye elingundoqo
Eyaziwa ngokuba yi-keystone correction, isetyenziselwa ukuhlawulela ukuphazamiseka okubangelwa ngokubeka iprojekti kwi-angle eyahlukileyo yezehlo kune-angle eqhelekileyo yesikrini.
Ubukhulu kunye nobunzima
Kuya kufuneka uqwalasele uhlobo losetyenziso ozimisele ukulwenza ngeprojektha. Kukho ubungakanani obahlukeneyo: ukuba uya kuyisebenzisa rhoqo, cinga ukuthenga izixhobo ezincinci kwaye zilula ngobunzima.
Ingxolo
Xa ukhetha iprojektha, ingxolo ibalulekile. Iiprojektha zisebenzisa ifeni kunye nenkqubo engaphezulu okanye engaphantsi yokulahla ubushushu kunye nenkqubo yokubuyisela kwakhona.
Ingxolo idla ngokulinganiswa nge-dB (decibels) kwaye ixabiso elingaphantsi kwe-30 dB lidla ngokuba phantsi kwaye lingaphezulu kunokwamkelekileyo.
Izixhobo
Ngokuqhelekileyo, iprojektha ayixhotyiswanga ngenkqubo yomsindo. Ke ngoko, ekusebenzeni okuphezulu, kungcono ukuyidibanisa kunye nenkqubo enezithethi ezi-5 okanye ngaphezulu kunye neamplifier. Kwakhona, kuyenzeka ukuba ungeze i-tuner ukubukela amajelo e-TV emveli.
Ungalibali isikrini sokubonisa: yisisombululo kuphela esiya kukuvumela ukuba ube nemifanekiso egqibeleleyo kunye nethembekileyo, ngaphandle kokuphazamisa udonga apho iprojekti iphinda ivelise imifanekiso.
