Isikrini sevidyo sekuyisikhathi eside sisetshenziswe njengethuluzi lesethulo ebhizinisini nasekuzijabuliseni kwezebhizinisi, kanye nakwezinye izinhlelo eziphezulu kakhulu zokudlala ekhaya. Noma kunjalo, ama- video projectors ayatholakala kakhulu futhi angabizi kumthengi ojwayelekile. Hlola amathiphu athile awusizo ngaphambi kokuthenga iphrojekthi yakho yokuqala yevidiyo .
Izinhlobo ze-Projectors Project
Kunezinhlobo ezimbili ezinkulu ze-Projectors Project ezitholakalayo: DLP ( Digital Light Processing ) ne- LCD ( Liquid Crystal Display ). Ukwengeza, ezinye izinto ezihlukahlukene zokubukwa kwevidiyo ye-LCD ezisetshenziswayo yi- LCOS (i-Liquid Crystal ku-Silicon), i- D-ILA (i-Digital Imaging Light Amplification - eyakhiwe futhi isetshenziswe yi-JVC) ne- SXRD (i-Silicon Crystal Reflective Display - ithuthukiswe futhi isetshenziswe ngu-Sony) . Ukuze uthole imininingwane eyengeziwe, kufaka phakathi izinzuzo nezindleko zohlobo ngalunye, hlola ama- Basics esihlokweni somlingani wethu we- LCD Video Projector .
Izibani, ama-LED, nama-Lasers
Ngaphandle kobuchwepheshe be-LCD noma i-DLP engase isetshenziswe kwiprojekitha yevidiyo, enye into okufanele icatshangelwe ukuthi ngabe umthombo wokukhanya osetshenziselwa iphrojekithi isibani , i-LED noma i-Laser . Zonke izinketho ezintathu zinezinzuzo nezinkinga.
Ukusetshenziswa Okuhle Kakhulu Kwephrojekthi Yevidiyo
Amaprosesa asekhaya asetshenziselwa ukubuka ama-movie, ama-DVD, noma amabhayisikobho e-Blu-ray Disc. Uma ubukela i-TV evamile, iprojekti ye-LCD / DLP ingaba inketho ebiza kakhulu yezinkampani eziningi zephrojekthi esekelwe isibani njengoba isibhamu (umthombo okhanyayo) kuzodinga ukuguqulwa ngemuva kwamahora angu-3 000 kuya ku-4,000 wokubukwa, kanti amanye amaprojekthi ayenayo manje ngaphezulu kwamahora angu-5 000 noma ngaphezulu kwe-bulb life. Qhathanisa lokho nge-LCD noma i-OLED TV engadlulela amahora angu-60,000 noma ngaphezulu, naphezu kwesayizi encane yeskrini. Futhi, qiniseka ukuthi unesayizi elifanele ekamelweni lakho leprojekthi yakho.
Enye ukusetshenziswa okukhulu kweprojekti yevidiyo ukubuka amabhayisikobho ngaphandle kwehlobo.
Ukufaneleka
Ukubaluleka kubalulekile, hhayi nje ukukuvumela ukuba uhambe noma uhambe ngeprojekti yakho, kodwa ulungise ukufaka nokusetha. Futhi kwenza kube lula ukuzama ubukhulu bezinkrini, amabanga, namakamelo ahlukene ukuze ubone ukuthi yini ehamba phambili. Uma iphrojekthi yakho iphathekayo ungafaka ngisho neshidi kudonga olungaphandle (noma umnyango wesigaraji) ngesikhathi sasehlobo futhi ujabulele ama-movie akho-ku-movie!
Ukukhanya okukhanyayo nokukhanya
Ngaphandle kokukhipha okwanele, iphrojekitha ngeke ikwazi ukubonisa isithombe esicacile. Uma ukukhishwa okukhanyayo kuphansi kakhulu isithombe sizobukeka sidaka futhi sithobekile, ngisho nasendlini emnyama. Indlela engcono kakhulu yokuthola ukuthi ngabe iphrojekithi ikhipha ukukhanya okwanele ukukhiqiza izithombe ezikhanyayo, hlola isilinganiso se-ANSI Lumens. Lokhu kuzokutshela ukuthi kungakanani ukukhanya okungahle kwenziwe iphrojekthi. Ngokukhulumisana, abaprojekthi abane-ANSI Lumens noma ngaphezulu banokukhanya okwanele kokusetshenziswa kwendawo yaseshashalazini. Isayizi yamakamelo, usayizi wesibuko / ibanga, nokuxhumana okukhanya ukukhanya okuzokwenzeka kuyoba nomthelela wesidingo sokwedlula okungaphezulu noma okumbalwa .
Ukulinganisa okuhlukile
Ukuqhathaniswa kwesilinganiso kuqeda ukukhanya. Ukuqhathanisa ukulinganisa phakathi kwamaphethelo amnyama nomhlophe wesithombe. Izilinganiso eziphambene eziphezulu ziletha abamhlophe abamhlophe nabanyama abamnyama. Iprojekti ingaba nokulinganisa okukhulu kwe-Lumens, kodwa uma isilinganiso sokuphambene siphansi, isithombe sakho sizobukeka sageza. Ekamelweni elimnyama, isilinganiso sokuhlukanisa okungenani esingu-1,500: 1 sihle, kepha u-2,000: 1 noma ngaphezulu kubhekwa njengelungile.
Ukulingana kwePixel
Ukuphakama kwe-Pixel kubalulekile. Abacwaningi be-LCD ne-DLP banenombolo ehleliwe yamaphikseli. Uma iningi lokubukela kwakho i-HDTV, thola inani eliphakeme lokubala kwe-pixel njengokwenzeka (mhlawumbe 1920x1080). Ukubalwa kwamaphikseli okuzalwa ka-1024x768 kwanele iDVD. Noma kunjalo, izimpawu ze-720p ze-HDTV zidinga isibalo se-pixel esingu-1280x720 sokuboniswa komdabu, kuyilapho isignali yokufaka i-HDTV engu-1080i idinga inani le-pixel langokwemvelo lika-1920x1080. Uma unesidlali se-Blu-ray, cabanga ngeprojekti nge-1920x1080 isinqumo se-pixel yangokwezifiso kanye nekhono lokubonisa ifomethi ye- 1080p .
Ngaphezu kwalokho, uma ufisa ukungena ku-4K, ngaphandle kwezindleko ezengeziwe, akuwona wonke ama- projectors angu- 4K ahlinzeka isinqumo se-4K sangempela. Kubalulekile ukuthi uqonde ukuthi ama-4K video projectors asebenza kanjani nokuthi abhalwe kanjani ukuze wenze ukhetho oluhle lokusetha ekhaya.
Ukukhiqizwa kombala
Umbala wokukhiqiza ungenye into. Hlola amathoni enyama yemvelo nokujula kombala. Hlola ukuthi imibala ibheka kanjani ezindaweni eziqhakazile futhi ezimnyama zesithombe. Hlola izinga lokusimama kombala kusuka ekufakweni kokufaka, nokuthi ujwayele izinhlobo zezilungiselelo zesithombe ezihlinzeka ngephrojekithi yevidiyo. Wonke umuntu unomkhawulo omncane ekuboneni kombala nalokho okubukeka kujabulisayo. Bheka ngokucophelela.
Imigomo
Qiniseka ukuthi iphrojekithi inezimpendulo ozidingayo. Wonke ama-projectors wevidiyo kulezi zinsuku, anikeze izimpendulo ze-HDMI , futhi abaningi bephrojekithi bane- VGA kanye / noma izimpendulo ze- DVI zamakhompyutha.
Kodwa-ke, uma unomthombo omdala omthombo osebenzisa uxhumano olunjenge- composite ne- S-video emithonjeni ye-analog, noma imiphumela yomsindo wevidiyo - ama-video amaningi amasha wevidiyo abangeke anikele ngalezi zinketho noma anganikeza ukhetho olulodwa lwevidyo. Ngakho-ke, lapho uthengela iphrojekithi, kubalulekile nakanjani ukuqiniseka ukuthi linokuxhumana okudingayo.
Ungalokothi ukhohlwe isikrini!
Izikrini zivela ezimfashini, ubukhulu, namanani ahlukene. Uhlobo lwesikrini olungcono kakhulu luxhomeke kuphrojekitha, i-angle yokubukwa, inani lokukhanya okukhanyayo ekamelweni, nomkhawulo weskrini kusuka kusikrini.
Okubalulekile
Ukusetha indawo yaseshashalazini ngeprojekti yevidiyo engxenyeni yayo kungakhulisa ngempela isipiliyoni sokuzijabulisa ekhaya. Kodwa-ke, ungafinyeleli esikhwameni sakho nokuthi yikuphi okukhethekile noma okusetshenzisiwe - sebenzisa amathiphu afakwe ohlwini futhi achazwe kulesi sihloko ukukuqondisa ekutholeni iphrojekthi ehamba phambili yezidingo zakho.
