Ukusebenzisa i-lasers ukukhanyisa isipiliyoni sakho sokubukela ekhaya
Amaprosesa wevidiyo aletha umuzwa we-movie ohambayo ngekhono lokubonisa izithombe ezikhulu kakhulu kunezinkampani eziningi ze-TV ezinganikeza. Noma kunjalo, ukuze iprojector yevidiyo isebenze ngokusemandleni, kufanele inikeze isithombe esicwebezelayo futhi sibonise ububanzi bombala obanzi.
Ukuze ufeze lo msebenzi, umthombo okhanyayo owakhiwe onamandla uyadingeka. Emashumini ambalwa adlule, ubuchwepheshe obuhlukahlukene bokukhanya buye kwaqashwa, ne-Laser ibe yamuva ukungena kule ndawo.
Ake sibheke ukuvela kwemithombo yomthombo wokukhanya esetshenziswe kumavidiyo weprojekti nokuthi ama-Lasers ashintsha kanjani umdlalo.
I-Evolution kusuka ku-CRTs kuya emaLampeni
Ekuqaleni, ama-video namaprosesa asetshenziselwa ubuchwepheshe be-CRT (cabanga ngamathoyizi amancane kakhulu we-TV). Ama-tubes amathathu (obomvu, eluhlaza, okwesibhakabhaka) anikeze kokubili imininingwane edingekayo yokukhanya nesithombe.
Ithebhu ngayinye ikhonjiswe esibukweni ngokuzimela. Ukuze ubonise uhla olugcwele lwemibala, amashubhu kwakudingeka aguqulwe. Lokhu kusho ukuthi ukuxuba umbala empeleni kwenzeke ngqo esikrinini hhayi ngaphakathi kwiprojekitha.
Inkinga ngamatayipi akuyona nje isidingo sokuguqula ukugcina ubuqotho besithombe esicacisiwe uma ishubhu esisodwa siphelile noma sihlulekile ngaphambi kwesikhathi, zonke izilimo eziyizigaxa ezintathu kwakufanele zithathwe indawo ukuze zonke zihlolwe umbala ngendlela efanayo. Izilimo eziyizigaxa nazo zazifudumala kakhulu futhi kwakudingeka zikhohliwe "ama-gel" akhethekile noma "oketshezi".
Ukuze uyiqede, bobabili abaprojekthi be-CRT nama-TV abonakalayo badla amandla amaningi.
Amaprosesa asekelwe e-CRT asebenzayo manje ayedabuli kakhulu. Izibhamu zithathelwe kabusha izibani, zihlangene nezibuko ezikhethekile noma isondo elimibalabala elihlukanisa ukukhanya zibe obomvu, oluhlaza okwesibhakabhaka nohlaza okwesibhakabhaka, kanye ne "chip chip" ehlukile ehlinzeka ngemininingwane yesithombe.
Kuye ngohlobo lwe-imaging chip elisetshenziswa (i- LCD, i-LCOS , i- DLP ), ukukhanya okuvela esibani, izibuko, noma isondo lemibala, kufanele kudlule noma kubonakalise i-chip imaging, eyenza isithombe osibona esibukweni .
Inkinga Ngezibani
Abacwaningi be-LCD / LCOS kanye ne-DLP "isibani-ne-chip" basuke beqhamuka kakhulu kusuka ngaphambili kwabo base-CRT-based, ikakhulukazi ngesilinganiso sokukhanya abangakhipha. Kodwa-ke, izibani zilokhu zichitha amandla amaningi okukhipha yonke i-spectrum yokukhanya, yize kuphela imibala eyinhloko ebomvu, eluhlaza, nohlaza okwesibhakabhaka idinga ngempela.
Yize kungeyona embi njenge-CRTs, izibani ziyakudla amandla amaningi futhi zikhiqize ukushisa, okudingekile ukuthi kusetshenziswe umshayeli onomsindo wokugcina izinto zipholile.
Futhi, kusukela okokuqala uvula iprojector yevidiyo, isibani siqala ukuphela futhi ekugcineni sizocima noma sishiswe (ngokuvamile emva kwamahora angu-3 000 kuya ku-5,000). Ngisho nama-tubs ahlolwe yi-CRT, njengamahlumela amakhulu futhi ayingozi, ahlala isikhathi eside kakhulu. Ukuphila okufishane kwezibani kudinga ukushintshwa ngezikhathi ezithile ngezindleko ezengeziwe. Ukufunwa kwanamuhla kwemikhiqizo eco-friendly (izibani eziningi zeprojekti nazo ziqukethe i-Mercury), kudinga enye engenza umsebenzi ube ngcono.
I-LED eya Ekuhlanguleni?
Enye indlela yezibane: Ama-LED (ama-Diode Ekhanyayo). Ama-LED amancane kunalesi sibani futhi angabelwa ukukhipha umbala owodwa (obomvu, obuluhlaza, noma obuluhlaza).
Ngosayizi wabo omncane, amaprosesa angenziwa ahlanganiswe kakhulu - ngisho ngaphakathi into encane njenge-smartphone. Ama-LED asebenza kahle kakhulu kunezibani, kodwa asenobuthakathaka obuncane.
- Okokuqala, ama-LED awaqhathanisi njengezibani (ukuqhathanisa iphrojekthi ye-LED vs. isibani esilinganisweni samanani).
- Okwesibili, ama-LED awashicileli ngokubambisana. Lokhu kusho ukuthi njengoba izigqoko zokukhanya zishiya umthombo wokukhanyisa we-chip chip based ku-LED, zinekhono lokusabalalisa, okusho ukuthi, nakuba ziqondile kakhulu kunesikhanyiso, zisalokhu zingasebenzi kahle.
Esinye isibonelo seprojekti yevidiyo esetshenziswa ama-LED emthombo wayo wokukhanya yi-LG PF1500W.
Faka i-Laser
Ukuxazulula izinkinga zezibani noma ama-LED, umthombo wokukhanya we-laser ungasetshenziswa.
I-Laser imele i- L ight A mplification ngu- S mission e- timulated ye- R .
Ama-Lasers asetshenziswe kusukela ngo-1960 njengamathuluzi ekuhlinzekwe kwezokwelapha (njengeLASIK), emfundweni nasebhizinisini njengama-laser pointers nokuhlola ibanga, futhi amasosha asebenzisa ama-lasers ezinkambisweni zokuqondisa, kanye nezikhali ezinokwenzeka. Futhi, i-Laserdisc, i-DVD, i-Blu-ray, i-Ultra HD Blu-ray, noma i-CD player, sebenzisa i-lasers ukuze ufunde imigodi ku-disc equkethe umculo noma okuqukethwe kwevidiyo.
I-Laser ihambela iphrojekthi yevidiyo
Uma isetshenziselwa njengomthombo wokukhanya wevidiyo, i-Lasers inikeza izinzuzo eziningana ngaphezu kwezibani nama-LED.
- Ama-Lasers axazulula inkinga yokusabalalisa ukukhanya ngokukhipha ukukhanya ngokubumbene. Njengoba ukukhanya kuphuma ku-laser kuyisimo esisodwa, esiqinile, esiqinile, esine "ubukhulu" obugcinwe ngaphesheya ngaphandle uma kushintshiwe ngokudlula ngamalensi engeziwe.
- Ukusetshenziswa Kwamandla Amandla. Ngenxa yesidingo sokunikeza ukukhanya okwanele ukuze iphrojista ibonise isithombe esikrinini, isibani sidla amandla amaningi. Noma kunjalo, njengoba i-Laser ngayinye idinga ukukhiqiza umbala owodwa (ofana ne-LED), iyasebenza kakhulu.
- Ukwenyuka kokukhanya kwe-Light nge-generation encane yokushisa-okubaluleke kakhulu ku- HDR , edinga ukukhanya okukhulu ukusebenza okugcwele.
- Inikeza ukusekelwa komdlalo webala lombala obanzi kanye nokufaka umbala ocacile obala.
- Ngokushesha isikhathi se-Instant On / Off esisheshayo kufana nalokho okuzwayo lapho uvula i-TV futhi uvale.
- Ukuphila okuwusizo isikhathi eside-amahora angu-20,000 asetshenziswayo noma ngaphezulu kufinyeleleka kalula, kususa isidingo sokushintshwa kwezibani ngezikhathi ezithile.
I-Mitsubishi LaserVue
I-Mitsubishi yiyona yokuqala yokusebenzisa i-lasers kumkhiqizo womkhiqizo we-projector-based. Ngonyaka ka-2008, bafaka i-LaserVue emuva kokubukwa kwe-TV. I-LaserVue isebenzisa isimiso sokuhlola esisekelwe e-DLP ngokuhambisana nomthombo wokukhanya we-laser. Ngeshwa, i-Mitsubishi inqamule wonke ama-TV abo abheke ngemuva (kufaka phakathi i-LaserVue) ngasekupheleni kuka-2012.
I-LaserVue TV isebenze ama-lasers amathathu, eyodwa ibe yilabo abomvu, eluhlaza, nohlaza okwesibhakabhaka. Lezi zintambo ezintathu ezikhanyayo zaboniswa nge-Chip DLP DMD, eyayiqukethe imininingwane yesithombe. Izithombe ezitholakalayo zabe seziboniswa esikrinini.
I-TV ye-LaserVue inikeze kahle kakhulu ukukhishwa kwamandla okukhanya, ukunemba kombala, nokuphambene. Kodwa-ke, yayibiza kakhulu (isethi yama-65-intshi yayingenani ku-$ 7,000) futhi nakuba ilula kakhulu kunezingcingo eziningi eziseqophelweni eliphezulu, yayisenamandla kunama-TV e-Plasma ne-LCD atholakalayo ngaleso sikhathi.
Iphrojekthi yevidiyo ye-Laser Light Source Configuration Examples
QAPHELA: Izithombe ezibalwe ngenhla kanye nezincazelo ezijwayelekile zikhona-kungase kube ukuhluka okuncane kuye ngokuthi umenzi noma isicelo.
Nakuba ama-LaserVue TVs engatholakali, ama-Lasers ashintshiwe ukuze asetshenziselwe ukusetshenziswa njengomthombo wokukhanya wamaphrosesa wevidiyo wendabuko kumalungiselelo amaningana.
I-RGB Laser (DLP) - Lokhu kulungiselelwa kufana nalokhu okusetshenziswe ku-Mitsubishi LaserVue TV. Kukhona ama-lasers angu-3, okuletha ukukhanya okubomvu, okuluhlaza okwesibhakabhaka, nolunye oluhlaza okwesibhakabhaka. Ukukhanya okubomvu, okuluhlaza okwesibhakabhaka nokuhlaza okwesibhakabhaka kuhamba nge-de-speckler, "umbhobho wokukhanya" omncane nomhlangano we-lens / prism / DMD Chip, futhi ngaphandle kwiprojekitha esibukweni.
I-RGB Laser (i-LCD / LCOS) - Njengoba nje nge-DLP, kunama-lasers angu-3, ngaphandle kokuthi esikhundleni sokubukisa ama-chips e-DMD, imishayo emithathu ye-RGB idluliselwa kuma-chips amathathu e-LCD noma i-3 LCOS chips (i-chip ngayinye ibelwe obomvu, obuluhlaza, nohlaza okwesibhakabhaka) ukukhiqiza isithombe.
Nakuba uhlelo lwama-laser olu-3 okwamanje lusetshenziselwa ezinye zeprojekthi ze-cinema yezohwebo, ngenxa yezindleko zalo, okwamanje alusetshenzisiwe kubakhiqizi be-DLP noma i-LCD / LCOS abaxhasi-abathengi-kodwa kukhona okunye, okunye okuphansi kwezindleko ezithandwa kakhulu ekusetshenzisweni kwamaprosesa - uhlelo lwe-Laser / Phosphor.
I-Laser / Phosphor (DLP) - Lolu hlelo luyinkimbinkimbi kangako ngokwezinga elidingekayo lama-lens nezibuko ezidingekayo ukuze iphrojekthi ifakwe isithombe esiphelele, kodwa ngokunciphisa inani lama Lasers kusuka ku-3 kuya ku-1, izindleko zokuqalisa zinciphisa kakhulu.
Kulesi simiso, iLaser eyodwa iveza ukukhanya okwesibhakabhaka. Ukukhanya okwesibhakabhaka kuhlukaniswa kabili. Enye ibhamvu iyaqhubeka nayo yonke enye injini ye-DLP, kanti enye ishaya isondo elijikelezayo elinama-phosphors aluhlaza okwesibhakabhaka nokuphuzi, okwenza ukuthi kube nemibhoshongo emibili ehlaza okwesibhakabhaka nokuphuzi. Lezi zigaxa ezikhanyayo, zijoyina umgodi wokukhanya ohlaza okwesibhakabhaka, futhi bonke abathathu badlula ngesondo elikhulu lombala we-DLP, umhlangano we-lens / prism, futhi babonakalisa inkinobho ye-DMD, enezela ulwazi lomfanekiso kumxube wombala. Isithombe esiphelele sombala sithunyelwa kusuka kwiprojekitha kuya esibukweni.
Omunye wephrojekthi we-DLP osebenzisa i-Laser / Phosphor inketho yi-Viewsonic LS820.
I-Laser / Phosphor (i-LCD / LCOS) - Ku-projection ye-LCD / LCOS, ukufaka uhlelo lokukhanya kwe-Laser / Phosphor kufana nelobalingisi be-DLP, ngaphandle kokuthi esikhundleni sokusebenzisa i-DLP DMD chip / Umbala wama Wheel, ukukhanya kudlule Ama-chips e-LCD noma aboniswa yi-3 LCOS chips (eyodwa ngayinye ebomvu, eluhlaza, nohlaza okwesibhakabhaka).
Noma kunjalo, i-Epson isebenzisa ukuhlukahluka okusebenzisa ama-lasers amabili, omabili avela ukukhanya okwesibhakabhaka. Njengoba ukukhanya okwesibhakabhaka kusuka kwelinye laser kudlula lonke injini yokukhanya, ukukhanya okwesibhakabhaka kusuka kwenye Laser kushaya isondo yellow phosphor, okuyinto, futhi, uhlukanisa ibhande blue ukukhanya zibe obomvu kanye nemifantu ukukhanya green. Izigxobo zokukhanya ezibomvu neziluhlaza okwakusanda kudalwa bese ujoyina uphahla oluhlaza oluhlaza okwesibhakabhaka futhi udlule kulo lonke i-injini yokukhanya.
Elinye iprojekthi ye-Epson LCD esebenzisa i-laser kabili ngokuhambisana ne-phosphor yi-LS10500.
I-Laser / i-Hybrid ye-LED (i-DLP) - Okunye okunye ukuhluka, okusetshenziswe ngokuyinhloko yi-Casio kwezinye zeprojekti yabo ye-DLP, yi-Laser / LED injini yokukhanya ye-hybrid.
Kule ukucushwa, i-LED ikhiqiza ukukhanya okubomvu okudingekayo, kuyilapho iLaser isetshenziselwa ukuveza ukukhanya okwesibhakabhaka. Ingxenye yesibhakabhaka sokukhanya okuluhlaza okwesibhakabhaka ihlukaniswe ibe yi-beam eluhlaza emva kokushaya isondo lombala we-phosphor.
Izigxobo zokukhanya ezibomvu, eziluhlaza, neziluhlaza okwesibhakabhaka ziyadlula ngaphakathi kwe-lens ye-condenser bese ziboniswa nge-Chip DLP DMD, ziqedile ukudala isithombe, esivezwa kwesikrini.
Iprojekti eyodwa ye-Casio ene-Laser / LED Light Hybrid Engine iyena-XJ-F210WN.
Okubalulekile - Kuya Laser Noma Akungakabi Laser
Amaprosesa ase-Laser anikeza inhlanganisela engcono kakhulu ekukhanyeni okudingekayo, ngokucacile kombala, nokusebenza kahle kwamandla kokubili ukusetshenziswa kwe-cinema nokusetshenziswa kwendawo yaseshashalazini.
Amaprosesa asekelwe ngamabhande amanje asebusayo, kodwa ukusetshenziswa kwe-LED, i-LED / Laser, noma imithombo yokukhanya ye-Laser iyanda. Ama-Lasers okwamanje asetshenziselwa inani elilinganiselwe lamaphrojekti wevidiyo, ngakho-ke ayoba abizayo kakhulu (Amanani avela ku-$ 1,500 angaphezulu kuka-$ 3,000-futhi acabange izindleko zeskrini, futhi kwezinye izimo, amalensi).
Kodwa-ke, njengoba ukutholakala kwanda futhi abathengi bathenga amayunithi amaningi, izindleko zokukhiqiza ziyokwehla, okwenza kube namaprosesa aseLazer aphansi-futhi acabangele izindleko zokufaka izibani ngokungahambisani nama-lasers.
Uma ukhetha iphrojekitha yevidiyo- akunandaba ukuthi imuphi umthombo wokukhanya owusebenzisayo, udinga ukulingana nemvelo yakho yokubukwa kwekamelo, isabelomali sakho, nemifanekiso kuzodingeka zikujabulise.
Ngaphambi kokunquma ukuthi isibani, i-LED, Laser, noma i-LED / Laser hybrid yindlela engcono kakhulu kuwe, funa ukuboniswa kohlobo ngalunye.
Ukuze uthole okwengeziwe kokukhipha ukukhanya kwevidyo yevidiyo, nendlela yokusetha iphrojekthi yevidiyo, bheka izihloko zethu zomngane: Ama- Nits, i-Lumens, ne-Brightness - Amaphrosesa we-TV vs Isiqophi nokuthi Ungasetha kanjani iphrojekthi yevidiyo
Iphuzu elilodwa lokugcina-Njengoba nje nge "TV TV" , i-laser (ama) esakhiweni asikhiqizi imininingwane yangempela esithombeni kepha inikeza umthombo wokukhanya okwenza abaprojekthi babonise izithombe ezigcwele imibala ebalazweni esikrinini. Noma kunjalo, kulula ukusebenzisa igama elithi "Laser Projector" esikhundleni sokuthi "iprojekti yevidiyo ye-DLP noma i-LCD ne-Light Source laser".
