Iyini i-projektha futhi isebenza kanjani

Iprojektha iyisisetshenziswa esibonakalayo esabalalisa ukukhanya ngaphandle ukuze kwakheke isibonisi esikrinini sokuqagela. Idivayisi ekhiphayo iyakwazi ukwamukela izithombe kumthombo wangaphandle (ikhompyutha, iselula, isidlali semidiya, ikhamera, njll.) futhi izibonise endaweni enkulu. Iprojektha yesimanje yedijithali iqukethe izingxenye ezintathu ezibalulekile:

1. Umthombo wokukhanya odala ukukhanya kwesithombe. Lesi isibani sensimbi se-halide, iyunithi ye-laser diode noma iyunithi ye-LED.
2. I-chip noma ama-chips akhiqiza okuqukethwe okubukwayo ngokusekelwe kusignali yomthombo wevidiyo . Imvamisa lokhu kuyidivayisi eyodwa ye-Digital Light Projection (DLP) micromirror, amaphaneli e-LCD amathathu, ama-LCoS chips amathathu (amakristalu awuketshezi ku-silicon).
3. Ilensi , kanye nezici zayo ezihlotshaniswayo zokubona, ezisetshenziselwa ukukhiqiza umbala nokuqukethwe kwephrojekthi esikrinini.

Amaphrojektha ayinqwaba angaphatheka, afakwe usilingi, aveze isithombe emabangeni amade. Okukhethwa kukho okuphathekayo kungasetshenziswa noma kuphi lapho kukhona indawo ekhanyayo. Amadivayisi amaningi afakwe imithombo yokufaka eminingi, izimbobo ze-HDMI zemishini yesizukulwane esisha, i-VGA yamadivayisi amadala. Amanye amamodeli asekela i-Wi-Fi, i-Bluetooth.

Isimiso sokusebenza kwezinhlobo ezahlukene zamaprojektha

Yini i-digital projector? Imele umvuthwandaba wobuchwepheshe obusukela emuva ku-obscura yekhamera kanye nelambu lomlingo, amaphrosesa amaslayidi asekuqaleni kwekhulu lama-20. Kudala, amaphrojektha ayethembele efilimini kuphela ukuze enze izithombe ezinyakazayo. Ubuchwepheshe babusetshenziswa emasinema ezentengiselwano kwaze kwaba ngu-2000.

Ngawo-1950, ama-video projektha asekelwe kumashubhu e-cathode ray (CRTs) abomvu, aluhlaza okwesibhakabhaka. Abanikazi betiyetha abaningi basekhaya basakhumbula amabhokisi amakhulu, asindayo anamaqhuqhuva abomvu, aluhlaza naluhlaza “amehlo”.

Namuhla, ifilimu isithathelwe indawo ngokuphelele yizinketho zedijithali ngokusekelwe kobunye bobuchwepheshe bokucubungula izithombe ezintathu: LCD, LCoS, DLP. Bonke ubuchwepheshe bunikeza izinzuzo – usayizi omncane nesisindo, isizukulwane sokushisa esiphansi, ukusetshenziswa kahle kwamandla we-projektha. Ngamunye wabo unamandla nobuthakathaka bezinhlelo zokusebenza ezahlukene.

I-LCD (i-liquid crystal display)

Umqambi weprojektha yokuqala ye-LCD emhlabeni, eyethulwa ngo-1984, nguGene Dolgoff. Ubuchwepheshe be-LCD busekelwe ku-cubic prism ehlanganisa ubuso obuthathu, okukhona kubo amaphaneli e-LCD agxunyekiwe ezingxenyeni ezibomvu, eziluhlaza okotshani neziluhlaza okwesibhakabhaka zesiginali yevidiyo. I-prism isetshenziselwa ukuguqula imisebe yokukhanya evela kumaphaneli e-RGB ngamanye abe ugongolo olulodwa. Iphaneli ngayinye ye-LCD iqukethe izigidi zamakristalu awuketshezi angaqondaniswa endaweni evulekile, evaliwe, evalwe kancane ukuze ukukhanya kudlule.
Ikristalu ngalinye eliwuketshezi liziphatha njengesango, elimelela iphikseli ngalinye. Njengoba ukukhanya okubomvu, okuluhlaza okotshani, nokuluhlaza okwesibhakabhaka kudlula kumaphaneli e-LCD, amakristalu awuketshezi avuleka futhi avale kuye ngokuthi ungakanani umbala ngamunye odingekayo kuleyo pixel ngesikhathi esithile. Lesi senzo silungisa ukukhanya, sidale isithombe esivezwa esikrinini.
Kwamanye ama-projektha e-LCD, umthombo wokukhanya uyilaser eluhlaza okwesibhakabhaka. Kumamodeli amaningi e-laser, okunye ukukhanya okuluhlaza okwesibhakabhaka okuvela ku-laser kushaya isondo elizungezayo eline-phosphor-coated elikhipha ukukhanya okuphuzi, bese lihlukaniswa libe izingxenye ezibomvu neziluhlaza kusetshenziswa izibuko ze-dichroic. Okunye ukukhanya kwelaser okuluhlaza okwesibhakabhaka kuthunyelwa kumthwebuli wesithombe oluhlaza okwesibhakabhaka.

I-DLP (I-Digital Light Processing)

Ubuchwepheshe be-DLP budume kakhulu kuma-projektha azo zonke izinhlobo nosayizi. Yasungulwa ngo-1987 ngu-Larry Hornbeck wase-Texas Instruments, umshini wokuqala osekelwe ku-DLP wethulwa yi-Digital Projection ngo-1997. Isebenza kanjani iprojektha yokucubungula ukukhanya kwedijithali? Ngokubonisa ukukhanya okucisha amaphaneli esibuko amancane abizwa ngokuthi ama-digital micromirror devices (DMDs). Zimelela uxhaxha lwezibuko ezincane, ngasinye sazo esisebenza njengephikseli ekhanyayo eyodwa ekulungisweni kokuboniswa.
Kunezinhlobo ezimbili ze-DLP – ene-chip eyodwa nezintathu. Insimbi ihlanganisa isondo lombala (elinezihlungi ezibomvu, eziluhlaza okwesibhakabhaka) elizungezayo ukuze likhiqize imibala elandelanayo. Ekupheleni kwedivayisi kukhona umthombo wokukhanya (isibani). Ikhipha ukukhanya esondweni lombala elijikelezayo futhi idlule ku-DMD.
Isibuko ngasinye sihlotshaniswa nephuzu lokukhanya. Lapho ukukhanya kuwela ezibukweni, zihambisana nomthombo walo ngokunyakaza okugobile ukuya phambili, emuva. Qondisa ukukhanya endleleni yelensi ukuze uvule iphikseli, futhi kude nendlela yelensi ukuze uyivale.

Amanye amaphrojektha e-DLP asezingeni eliphezulu anama-chips e-DLP amathathu ahlukene, ngalinye libe namashaneli abomvu, aluhlaza, naluhlaza. Iprojektha enama-chip amathathu ibiza ngaphezulu kuka-$10,000.

Ku-DLP, umthombo wokukhanya ungaba futhi i-laser eluhlaza okwesibhakabhaka, ejabulisa isondo le-phosphor ukuze likhiphe ukukhanya okuphuzi. Ihlukaniswe yaba izingxenye ezibomvu neziluhlaza, kuyilapho okunye ukukhanya okuluhlaza okwesibhakabhaka okuvela ku-laser kusetshenziselwa ukudala ngokuqondile ingxenye eluhlaza okwesibhakabhaka yesithombe. Ezinye izixazululo zidinga ukungeza i-laser yesibili ebomvu noma usebenzise amalaser ahlukene abomvu, aluhlaza okwesibhakabhaka. Amamodeli amaningana aphinde asebenzisa ama-LED abomvu, aluhlaza naluhlaza, nakuba engakhanyi njengamalaser. Umqondo we-DLP ugqugquzelwe izibuko zomlingo zamaShayina. I-flux ekhanyayo yama-projektha e-DLP ikhanya, ifanele amakamelo anokukhanya okuzungezile (amakilasi, amakamelo enkomfa). https://cxcvb.com/texnika/proektory-i-aksessuary/lazernye.html

I-LCoS

I-LCoS (I-Liquid Crystals on Silicon) ubuchwepheshe obuhlanganisa izimiso ze-DLP ne-LCD. I-General Electric ibonise ukulungiswa kwe-LCoS enesinqumo esiphansi emuva ngeminyaka yawo-1970, kodwa kwaze kwaba ngo-1998 lapho i-JVC yethula i-SXGA+ (1400×1050) isebenzisa ubuchwepheshe be-LCoS, inkampani obubiza nge-D-ILA (Direct Drive Image Light). Ngo-2005, u-Sony wakhipha imodeli yethiyetha yasekhaya eyi-1080p yokuqala, i-VPL-VW100, esebenzisa ukuqaliswa kwayo kwe-LCoS, i-SXRD (Silicon X-tal Reflective Display), elandelwa yi-JVC DLA-RS1.
I-LCoS iwubuchwepheshe obukhanyayo obusebenzisa amakristalu awuketshezi esikhundleni sezibuko ngazinye. Zisetshenziswa ku-substrate yesibuko esikhanyayo. Njengoba amakristalu awuketshezi evuleka futhi evala, ukukhanya kuvela esibukweni esingezansi noma kuvinjiwe. Lokhu kulungisa ukukhanya futhi kwakha isithombe. Amaphrojektha asuselwa ku-LCOS ngokuvamile asebenzisa ama-chips e-LCOS amathathu, elilodwa ngalinye ukuze lilinganise ukukhanya eziteshini ezibomvu, eziluhlaza, neziluhlaza. Le sistimu kuthiwa ikhiqiza umphumela omncane wesikrini somnyango, ongenawo “umthelela wothingo” namanye ama-artifacts ahlotshaniswa nesondo lombala le-single-chip DLP. Ubuchwepheshe busetshenziswa kuma-multimedia projektha aqondiswe ezinhlelweni ezibalulekile zokubuka, kumaphrojektha wetiyetha asekhaya asezingeni eliphezulu.
