Yikuphi i-DLP Technology
I-DLP imelela i-Digital Light Processing, okuyinto ubuchwepheshe bokubukwa kwevidiyo, eyenziwe yiTexas Instruments.
I-DLP tech ingasetshenziswa ezinhlobonhlobo zamapulatifomu wokubonisa ividiyo, kodwa isetshenziswe kabanzi kumavidiyo weprojekthi. Kubalulekile ukuthi uqaphele ukuthi esikhathini esidlule, ubuchwepheshe be-DLP basetshenzisiwe kumaThelevishini athile abukela emuva (ama-TV angakabonakali ayatholakali).
Amaprosesa amaningi wevidiyo ekusetshenzisweni kwabathengi abasebenzisa izithombe zephrojekthi yeThekhnoloji ye-DLP esibukweni besebenzisa inqubo elandelayo:
Isibani sidlula ngokukhanya kwesondo elimibalazayo, elithatha isisindo esisodwa (okuthiwa yi-Chip DMD) esinezibuko ezibonakalayo ezibukwayo ezincane. Amaphethini wokukhanya abonisiwe abese edlule ngokusebenzisa i-lens, futhi afike esikrinini.
I-DMD Chip
Esemqoka kuwo wonke amavidiyo we-DLP i-DMD (i-Digital Micromirror Device). Lolu uhlobo lwe-chip oluhlelekile ukuze wonke amaphikseli abe isibuko esibonakalisayo. Lokho kusho noma kuphi kusuka kumuntu oyedwa kuya kwesigidi wamamitha ama-micromirror wezigidi ku-DMD ngayinye, kuye ngokuthi isinqumo sokuboniswa okuhloswe nokuthi isivinini sokugwedla esibukweni silawulwa kanjani.
Njengoba umthombo wesithombe wesithombe uboniswa ku-chip DMD. I-micromirror ku-chip (khumbula: i-micromirror ngayinye imelela i-pixel eyodwa) bese ihamba ngokusheshisa njengoba isithombe sishintsha.
Le nqubo ikhiqiza isisekelo se-grayscale yesithombe. Khona-ke, umbala wengezwa njengoba ukukhanya kudlula ngesondo elisha elimibalabala eliphakeme futhi liboniswa nge-micromirror kwi-chip ye-DLP njengoba ihamba kancane noma isuka kumgqa wombala nomthombo wokukhanya.
I-degree of inclination ye micromirror ngayinye ehambisana nesondo elimibalabala elimibalazayo lichaza isakhiwo sombala wesithombe esicacisiwe. Njengoba ukukhanya okukhulunywe ngokukhanyayo kukhishwa kwamakhamera-micromirror, ithunyelwa nge-lens futhi kungalinganiselwa esikrinini esikhulu esifanele ukusetshenziswa kwendawo yaseshashalazini.
I-3-Chip DLP
Enye indlela i-DLP eqaliswa ngayo (ekwakhiweni eliphezulu lokudlala ekhaya noma ukusetshenziswa kwe-cinema yezokuhweba) ukusebenzisa i-Chip DLP ehlukile kumbala ngamunye oyinhloko. Lolu hlobo lokuklama luqeda isidingo samasondo ombala ojikelezayo.
Esikhundleni samasondo ombala, ukukhanya okuvela emthonjeni owodwa kudluliselwa emgodini, okudala imithombo ekhanyayo ebomvu, eluhlaza, nohlaza okwesibhakabhaka. Imithombo yokukhanya ehlukaniswayo iboniswa kuzo zonke izinhlamvu ezikhethwe umbala ngamunye oyinhloko, futhi kusukela lapho, zifakwe esikrinini. Lolu hlelo lokusebenza lubiza kakhulu, uma kuqhathaniswa nomzila wesondo wemibala, yingakho kungavamile ukutholakala kubathengi.
I-LED ne-Laser
Nakuba i-3-Chip ye-Chip DLP iyabiza kakhulu ukusebenzisa, ezinye izindlela ezimbili ezingabizi kakhulu zisetshenzisiwe ngempumelelo (nangaphezulu kakhulu) ukuqeda isidingo samasondo ombala omibalazayo.
Enye indlela ukusebenzisa umthombo wokukhanya we-LED. Ungaba ne-LED ehlukile kumbala ngamunye oyinhloko, noma i-LED emhlophe ihlukaniswe ngemibala eyinhloko isebenzisa i-prism noma izihlungi zombala. Lezi zinketho azigcini nje kuphela isidingo samasondo ombala, kodwa ziveza ukushisa okuncane, futhi zidonsa amandla angaphansi kwesibani sendabuko. Ukusetshenziswa kakhudlwana kwalolu khetho kuye kwaphakamisa isigaba semikhiqizo ebizwa ngokuthi iProo Projectors.
Enye indlela yokusebenzisa imithombo ye- Laser noma ye-Laser / ye-LED Hybrid, efana nesisombululo se-LED kuphela, ayinqamuleli kuphela isondo lombala, ikhiqiza ukushisa okuncane, futhi idonse amandla amancane, kodwa futhi isebenza ekuthuthukiseni ukukhiqiza umbala nokukhanya. Noma kunjalo, indlela ye-laser iyabiza ngaphezu kwe-LED eqondile noma okukhethwa kukho kweLamp / Umbala we-Wheel (kodwa kusengabizi kangcono kune-3-chip option).
I-DLP Imidwebo
Nakuba "i-chip eyodwa ne-wheel wheel" inguqulo ye-DLP itheknoloji ingabizi kakhulu, futhi ingaveza imiphumela emihle kakhulu ngokwemibala nokuphambene, kunezinselelo ezimbili.
Enye impendulo yinani lomkhiqizo wokukhanya ombala (ukukhanya kombala) akusizinga elifanayo njengokukhishwa okukhanyayo okumhlophe - ukuze uthole imininingwane eyengeziwe funda isihloko sami: Ama-Projectors Video neBrightness Brightness .
Ukwehluleka okwesibili kumaphrojekti evidiyo ye-DLP abathengi kuba khona "I-Rainbow Effect".
Umphumela we-rainbow yi-artifact eyaziveza njengembala emfushane yemibala ephakathi kwesikrini namehlo lapho umbukeli ebukeka ngokushesha kusuka ngakwesokunene esibukweni noma abukeka ngokushesha kusukela kwesikrini kuya ngaphesheya kwekamelo. Le mibala yemibala ibonakala njengamabhodlela amancane okuqhuma.
Ngenhlanhla, le mphumela ayitholakali njalo, futhi abantu abaningi abanakho ukuzwela kulokhu nhlobo. Nokho, uma uzwela ngalokhu, kungaphazamisa. Ukubheka kwakho umphumela wempuphu kufanele kucatshangelwe uma uthenga iprojekti yevidiyo ye-DLP.
Futhi, ama-video we-DLP video asebenzisa i-LED noma i-Laser umthombo wokukhanya awunamathuba amancane okubonisa umphumela we-rainbow, njengoba isondo lombala elikhanyayo alikho.
