Yiyiphi i-DLP Technology
I-DLP imele i-Digital Light Processing, eyiyo ubugcisa beprojekthi ye-video, eyenziwa yiTexas Instruments.
I-tech ye-DLP ingasetyenziselwa kwiindidi zeziboniso zevidiyo, kodwa zisetyenziswa kakhulu kwiiprojekti zevidiyo. Kwakhona kubalulekile ukuqaphela ukuba kwixesha elidlulileyo, iteknoloji ye-DLP yayisetyenziswe kwiiTV ezisekelwe emva zangaphambili (iiTV ezibonakalayo zangasemva azikho).
Uninzi lweeprojekti zevidiyo zokusetyenziswa kwabathengi abasebenzisa imifanekiso yeprojekthi ye-teknoloji ye-DLP kwisikrini usebenzisa inkqubo elandelayo:
Isibane sidlula ngokukhanya kwinqwelo ejikelezayo, leyo leyo inokuthi ikhuphe ngaphandle kwenkqubo eyodwa (ebizwa ngokuba yi-DMD chip) ene-mirror-sized mirror-mirror. Iipateni zokukhanya ezibonisiweyo zigqithise nge-lens, kwaye kwi-skrini.
I-DMD Chip
Kwinqanaba leprojekthi yevidiyo yeDLP yi-DMD (i-Digital Micromirror Device). Olu luhlobo lwe-chip olulungelelaniso ukuze yonke i-pixel ibone isibuko. Oku kuthetha naphi na ukuya kwesinye ukuya kwii-miliyri ye-micromirror kwi-DMD nganye, kuxhomekeke kwisisombululo esibonakalisiweyo kunye nendlela i-mirror ishayela ngayo isantya.
Njengoko umthombo wesithombe somfanekiso uboniswa kwi-Chip DMD. I-micromirror kwi-chip (khumbula: nganye i-micromirror imele i-pixel enye) uze ujike ngokukhawuleza njengoko umfanekiso uguquka.
Le nkqubo ikhiqiza isiseko se-grayscale yomfanekiso. Emva koko, umbala uyongezwa njengoko ukukhanya kudlulela kwivili elijikelezayo eliphezulu lokujikeleza isondo kwaye kubonakaliswa kweminye micromirrors kwi-chip ye-DLP njengoko ijikeleza ngokukhawuleza okanye isuka kwimibala yesondo kunye nomthombo wokukhanya.
Iqondo lokutshintsha kwe-micromirror nganye kunye nevili elijikelezayo ngokukhawuleza libonisa isakhiwo sombala wesithombe esicetywayo. Njengoko ukukhanya okwenziwe ngokugqithiseleyo kubonkcoza kwi-micromirrors, ithunyelwa kwi-lens kwaye iyakucelwa kwisikrini esikhulu esifanelekileyo sokusetyenziswa kwesekhaya.
3-Chip DLP
Enye indlela i-DLP iphunyezwa ngayo (kwindawo yokuzonwabisa yasekhaya eliphezulu okanye usetyenziso lwe-cinema yokuthengisa) kukusebenzisa i-Chip DLP eyahlukileyo kumbala ngamnye oyintloko. Olu hlobo loyilo luphelisa isidingo sokujikeleza kwesondo.
Esikhundleni sothutho lombala, ukukhanya okuvela kumthombo omnye kudluliselwa kwi-prism, edala imithombo ekhanyayo ebomvu, eluhlaza, kunye nohlaza. Imithombo yokukhanya ekwahlukanayo iboniswa nganye kwiipipi ezikhethiweyo kumbala ngamnye oyintloko, kwaye ukusuka apho, iprojekthi kwisikrini. Lolu hlelo lubiza kakhulu, xa kuthelekiswa nendlela yokwenza umbane, oko kutheni kungabonakali kubakho abathengi.
I-LED kunye neLaser
Nangona iteknoloji ye-Chip DLP ye-3 iyabiza kakhulu ukuphumeza, ezinye ezimbini, iindlela ezingabizi ngaphantsi ziye zasetyenziswa ngokuphumelelayo (kunye nangaphezulu) ukuphelisa isidingo sokujikelezwa kwesondo.
Enye indlela kukusebenzisa umbane wokukhanya kwe-LED. Unokuba ne-LED eyahlukileyo kumbala ngamnye oyintloko, okanye i-LED emhlophe ihlukaniswe ngemibala ephambili usebenzisa i-prism okanye i-filters. Ezi zikhetho azigcini nje ukuphelisa imfuno yesondo lombala, kodwa zivelisa ubushushu obuncinci, kwaye zithatha amandla angaphantsi kwesibane senkcubeko. Ukusetyenziswa okongeziweyo kwalolu khetho kuye kwavelisa uluhlu lwemveliso ebizwa ngokuba yiProo Projectors.
Enye indlela yokusebenzisa imithombo yeLaer okanye iLerer / LED ye-Hybrid imithombo yemithombo, efana nesisombululo se-LED kuphela, ayinakususa kuphela isondo sombala, ivelise ukushisa okuncinane, kwaye idonsa amandla angaphantsi, kodwa iyakwenza ukuphucula umbala kunye nokukhanya. Nangona kunjalo, indlela ye-laser iyabiza ngaphezu kwe-LED eqondekileyo okanye i-Lamp / Color Wheel ongakhetha (kodwa isabibiza ngaphaya kohlobo lwe-3-chip).
DLP Iintsilelo
Nangona "i-chip-one-wheel color" inguqulelo yeTheknoloji ye-DLP ifikeleleke kakhulu, kwaye ivelise iziphumo ezilungileyo kakhulu ngokwemibala kunye nokuphambene, kukho izinto ezimbini ezingenakwenzeka.
Enye impendulo yomlinganiselo ngumlinganiselo wokukhanya kombala (ukukhanya kombala) akukona kwinqanaba elifanayo njengemveliso yokukhanya emhlophe - ukuze ufumane iinkcukacha ezingakumbi funda i-athikili yam: Iiprojekithi zeVidiyo kunye nokuBhanya kweMbala .
I-backback yesibili kumaprojekti evidiyo ye-DLP yekhompyutha ikhona "I-Rainbow Effect".
Umphumo wempuphu yi-artifact eyazibonakalisa njengombala omfutshane wembala phakathi kwesikrini kunye namehlo xa umbukeli ejonga ngokukhawuleza ukusuka kwicala ukuya ecaleni kwesikrini okanye ekhangele ngokukhawuleza esuka kwesikrini ukuya kwicala legumbi. Le mibala yemibala ibonakala njengeemvula ezincinci.
Ngethamsanqa, esi siphumo asikho rhoqo, kwaye abantu abaninzi abanalo uvakalelo kule nxalenye nhlobo. Nangona kunjalo, ukuba uyayiqonda le nto, kunokuphazamisa. Ukuthinteka kwakho kwimpembelelo yemvula kufuneka kuthathelwe ingqalelo xa uthenga iprojekti yevidiyo ye-DLP.
Kwakhona, iiprojekti zevidiyo ze-DLP ezisebenzisa i-LED okanye umthombo wokukhanya weLaser azincinci ukubonisa umonakalo we-rainbow, njengokuba isondo lombala okhethiweyo alikho.
Iinkcukacha ezithe vetshe
Ukujonga ngakumbi ubugcisa obunzulu ngendlela i-DLP iteknoloji kunye ne-DMD esebenzayo, khangela ividiyo esuka kwi-Applied Science.
