Ukusebenzisa i-lasers ukukhanyisa amava akho okubukela ekhaya
Iiprojekti zevidiyo zizisa i-experience-experience experience ekhaya kunye nokukwazi ukubonisa imifanekiso eninzi kunokuba ezininzi iiTV zingabonelela. Nangona kunjalo, ukwenzela ukuba iprojekti yevidiyo isebenze ngokufanelekileyo, kufuneka inikeze umfanekiso oqhaqhawulekileyo kwaye ubonise uluhlu olubanzi lwemibala.
Ukufezekisa lo msebenzi, umthombo onamandla owakhiwe ngaphakathi ofunekayo. Kule minyaka emininzi edlulileyo, ubuchwepheshe obuvela kumbane oqhelweyo buye baqeshwa, kunye neLaser ibe yakutsha ukungena kwi-arna.
Makhe sijonge kwi-tech source source usetyenziso kwiiprojekti zevidiyo kunye nendlela iLasers eguqula ngayo umdlalo.
I-Evolution ukusuka kwi-CRTs ukuya kumaLampu
Ekuqaleni, iiprojekti zevidiyo kunye nama-TV aqikelelwe asebenzisa i-CRT iteknoloji (cinga kakhulu iibhubhu ezincinane zeTV). Iibhubhu ezintathu (obomvu, eluhlaza, eluhlaza okwesibhakabhaka) zanikezela zombini inkcazelo ebalulekileyo yokukhanya kunye nekiso.
Nganye ityhubhu iboniswe kwisikrini ngokuzimela. Ukuze ubonise uluhlu olupheleleyo lwemibala, iibhubhu zafuneka ziguquke. Oku kuthetha ukuba ukudibanisa umbala okwenziweyo kwenzeka ngqo kwesikrini kwaye kungengaphakathi kwiprojekti.
Ingxaki ngeethubhu akuyona nje isidingo sokuguqulwa ukugcina ingqibelelo yomfanekiso oqikelelweyo ukuba enye ityhubhu yaphela okanye yahluleka ngaphambi kwexesha, zonke iiphubhu ezintathu zafuneka zitshintshwe ukuze zonke zibonise umbala ngendlela efanayo. Ii-tubes nazo zafudumala kakhulu kwaye zafuneka zicolile nge "gels" ezikhethekileyo okanye "i-liquid".
Ukukhupha phezulu, iiprojekisti ze-CRT kunye neTV zibonise amandla amaninzi.
Iiprojekti ezisekelwe kwiCRT ezisetyenziswayo ngoku ziyinqabile. Izibhabhane ziye zatshintshwa izibane, zidibene nezibuko ezikhethekileyo okanye ivili lesiganeko esahlukanisa ukukhanya ebomvu, eluhlaza, kunye nohlaza okwesibhakabhaka, kunye ne "chip chip" ehlukile.
Ngokuxhomekeka kuhlobo lwe-chip imaging elisetyenziswayo ( iLCD, iLCOS , i- DLP ), ukukhanya okuvela kwisibane, izibuko, okanye ngesondo lombala, kufuneka kudlule okanye kubonakaliswe kwi-chip imaging, eyenza umfanekiso owubonayo kwisikrini .
Ingxaki NgamaLampu
I-LCD / LCOS kunye ne-DLP "i-lamp-with-chip" iphrojekithi zixhamla kwi-CRT-based predecessors, ngokukodwa kwisixa sokukhanya abakwazi ukusibeka. Nangona kunjalo, izibane zichithe amandla amaninzi okuvelisa umbane wonke, nangona kuphela imibala ephambili ebomvu, eluhlaza, kunye nobuluhlaza imfuneko.
Nangona kungenjalo kungalunganga njenge-CRTs, izibane zidla amandla amaninzi kwaye zivelise ukushisa, zifuna ukusetyenziswa komdlali onomsindo wokugcina izinto zipholile.
Kwakhona, ukusuka okokuqala uvula iprojekti yevidiyo, isibane siqala ukutshabalalisa kwaye ekugqibeleni siza kutsha okanye sitshise (ngokuqhelekileyo emva kweeyure ezingama-3 000 ukuya kuma-5,000). Nangona iiplabhu ezibonakalayo ze-CRT, zinkulu kwaye zinzima njengoko zazinjalo, zahlala ixesha elide. Ixesha elifutshane lemibane lifuna ukutshintshwa kwesoxesha ngeendleko ezongeziweyo. Imfuno yanamhlanje yemveliso eco-friendly (ezininzi izibane zeprojekti nazo ziqulethe i-Mercury), ifuna enye engenza umsebenzi ube ngcono.
I-LED kwi-Rescue?
Enye yezinye izibane: ii-LED (ii-Diode ezikhanyayo). Ii-LED zincinci kunelibane kwaye zingabelwa ukuba zikhuphe umbala omnye (obomvu, obuluhlaza, okanye obuluhlaza).
Ngobuncinane babo buncinci, iiprojekti zinokuthi zenziwe zidibanise ngakumbi-nangaphakathi kwinto encinane njenge-smartphone. Iimpawu ze-LED zisebenza ngokugqithiseleyo kunezibane, kodwa zinobuthathaka obuncinane.
- Okokuqala, ii-LED aziqhathanisi njengezibane (ukuthelekisa i-LED vs iprojekti yesibane kwinqanaba lexabiso elifanayo).
- Okwesibini, i-LED ayifaki ukukhanya ngokubambisana. Oku kuthetha ukuba njengoko iiplanga ezikhanyayo zishiya umthombo wokukhanya osuselwe kwi-LED, zikhokelela ekutshatyalaliseni, oku kuthetha ukuba, nangona zichanekile ngaphezu kwesibane, zisencinane.
Omnye umzekelo weprojekti yevidiyo eqeshe ii-LED ngokuvela kumthombo wayo wokukhanya yi-LG PF1500W.
Faka iLaser
Ukuxazulula iingxaki zezibane okanye ii-LED, umthombo wokukhanya weLasta ungasetyenziswa.
I-Laser imele i- L ight I- mplification yi- S e- timenti ye- E .
I-Lasers sele isetyenziswe ukususela ngo-1960 njengezixhobo ekutyunjeni kwezonyango (njengeLASIK), kwimfundo nakwezoshishino ngendlela ye-laser pointers kunye nokuhlola umgama, kwaye umkhosi usebenzisa ama-lasers kwizixhobo zokukhokela kunye nezixhobo ezikhoyo. Kwakhona, i-Laserdisc, i-DVD, i-Blu-ray, i-Ultra HD Blu-ray, okanye i-CD player, sebenzisa iilers ukuze ufunde imigodi kwi-disc equle umculo okanye umxholo wevidiyo.
I-Laser ihambelana neprojekthi yeprojekthi
Xa isetyenziswe njengomthombo wokukhanya kwiprojekithi yevidiyo, iiLasers zinika iingenelo ezininzi phezu kwezibane kunye nee-LED.
- I-Lasers isombulula ingxaki yokusabalalisa ngokukhanya ngokubonisa ukukhanya ngokubambisana. Njengoko ukukhanya kuphuma kwi-laser yinto enye, eqinile, i-boram, "ubukhulu" bayo bugcinwa ngaphesheya ngaphandle kokuba utshintshe ngokudlula iilensi ezingaphezulu.
- Ukusetyenziswa kwamandla aphantsi. Ngenxa yesidingo sokubonelela ukukhanya okwaneleyo kwiprojekti ukubonisa umfanekiso kwisikrini, isibane sisebenzisa amandla amaninzi. Nangona kunjalo, ekubeni iLaser nganye idinga kuphela ukuvelisa umbala omnye (ofana ne-LED), iyasebenza kakuhle.
- Uphuhliso olusanda kuveliswa ngoveliso oluthile- olubaluleke kakhulu kwi- HDR , efuna ukukhanya okukhulu ukusebenza ngokupheleleyo.
- Unika inkxaso ngenkxaso ebanzi yombala kunye nobungqina obucacileyo bombala.
- Ngokukhawuleza ku-Off / Off off-more-like like what you experience when you turn the TV off and off.
- Ubomi obuncedo obude obude-20,000 ukusebenzisa iiyure okanye ngaphezulu kufumaneke lula, ukuphelisa isidingo sokutshintshwa kweso sixhobo.
I-Mitsubishi LaserVue
I-Mitsubishi yileyokuqala ukusebenzisa i-lasers kumveliso wevidiyo womxhasi weprojekti. Ngomnyaka we-2008, bazisa i-LaserVue i-TV-projection TV. I-LaserVue isebenzise inkqubo yokucwangcisa okusekelwe kwi-DLP ngokudibanisa nomthombo wokukhanya kwelayisi. Ngelishwa, i-Mitsubishi ichithe yonke i-TV eyabonakaliswa kwangaphambili (kuquka i-LaserVue) ngasekupheleni kuka-2012.
I-LaserVue TV iqeshe iil lasers ezintathu, enye ibe yimibala ebomvu, eluhlaza kunye nohlaza okwesibhakabhaka. Iimitha ezintathu ezikhanyayo zaye zaboniswa kwi-chip DLP DMD, eyayineenkcukacha zengcaciso. Iimifanekiso eziphumo zaboniswa kwesikrini.
Iimvumi ze-LaserVue zinikezela ngamandla okuvelisa ukukhanya, ukuchaneka kombala, kunye nokwahlukana. Nangona kunjalo, babebiza kakhulu (i-65-intshi isethi yaxabiswa kwi-7,000 yeeRandi) kwaye nangona ilula ngaphezu kweeTV ezininzi ezisekudala, yayisabuninzi kuneTlasma kunye ne-LCD yeTV efumanekayo ngelo xesha.
Iprojekthi yeVidiyo ye-Laser Light Source Configuration Examples
QAPHELA: Imifanekiso engentla kunye neenkcazelo ezilandelayo ziyi-generic-ezinokuthi zibe ziintshintsho ezincinci kuxhomekeke kumenzi okanye isicelo.
Nangona ii-TV ze-LaserVue zingasatholakali, i-Lasers iye yachitshiyelwa ukuba isebenzise njengomthombo wokukhanya weprojekthi zevidiyo eziqhelekileyo kwiinkqubo ezininzi.
I-RGB Laser (DLP) - Olu luhlu lufana nelo lusetyenziswa kwi-Mitsubishi LaserVue TV. Kukho ii-lasers ezi-3, enye ebonisa ukukhanya okubomvu, enye eluhlaza, kunye nolunye oluhlaza okwesibhakabhaka. Ukukhanya okubomvu, okuluhlaza, nokuluhlaza kuhamba nge-de-speckler, "umbhobho olula" kunye ne-lens / prism / iDMD Chip, kunye neprojekti kwisikrini.
I-RGB Laser (i-LCD / LCOS) - Kanye njengoko ku-DLP, kukho i-lasers ye-3, ngaphandle kokuba kunokuba ibonakalise iipups ze-DMD, iiplanga ezintathu zokukhanya kwe-RGB zigqitywa kwii-chips ezintathu ze-LCD okanye zibonakaliswe kwi-chip LCOS ezintathu (i-chip nganye isabelwe ebomvu, eluhlaza, kunye nohlaza) ukuvelisa umfanekiso.
Nangona inkqubo ye-laser okwangoku isetyenziswa kwezinye iprojekthi zeprojekthi ze-cinema, ngenxa yeendleko zayo, ingasetyenzisiwe kwiprojekthi yeprojekthi ye-DLP okanye i-LCD / LCOS kumbane -projekthi-kodwa enye enye, iindleko ezisezantsi ezithandwa kakhulu kwiprojekti I-Laser / Phosphor system.
I-Laser / Phosphor (i-DLP) - Le nkqubo yinto encinci kancinci ngokwemiqathango efunekayo yeelensi kunye nezibuko ezifunekayo ukuze iphrojekthi ifumane umfanekiso ogqityiweyo, kodwa ngokunciphisa inani lama Lasers ukusuka kwi-3 ukuya kwi-1, indleko yokuphunyezwa iyancitshiswa kakhulu.
Kule nkqubo, enye iLaser iphuma ekukhanyeni okwesibhakabhaka. Ukukhanya okwesibhakabhaka kuyahlukana ezimbini. Inkuni enye iyaqhubeka kuyo yonke i-injini ye-DLP, ngelixa elinye lihlasela isondo elijikelezayo eliqukethe i-phosphors eluhlaza kunye nephuzi. Le mijelo yokukhanya edibeneyo, fakela i-bar light light, kwaye bonke abathathu badlula ngevili elikhulu lombala we-DLP, i-lens / prism assembly, kunye ne-DMD chip, eyongeza ulwazi lomfanekiso kumxube wombala. Umfanekiso ogqityiweyo umbala uthunyelwa ukusuka kwiprojekithi ukuya kwisikrini.
Umprojekti omnye we-DLP osebenzisa i-Laser / Phosphor inketho yi-Viewsonic LS820.
I-Laser / Phosphor (LCD / LCOS) - Kwiprojekti yeLCD / LCOS, ukubandakanya inkqubo yokukhanya ye-Laser / Phosphor ifana neye-projekthi ye-DLP, ngaphandle kokuba kunokusebenzisa i-DLP DMD chip / i-Wheel Wheel assembly, ukukhanya kungadlula Iipilisi ze-LCD ezi-3 okanye eziboniswayo kwi-3 LCOS chips (enye enye ibe ebomvu, eluhlaza, kunye nohlaza).
Nangona kunjalo, i-Epson isebenzisa ukuhlukahluka okusebenzisa ii-lasers ezi-2, zombini ezikhupha ukukhanya okwesibhakabhaka. Njengoko ukukhanya okwesibhakabhaka ukusuka kwelinye laser lidlula lonke i-injini yokukhanya, ukukhanya okwesibhakabhaka ukusuka kwenye iLaser kubetha isondo eliphuzi le-phosphor, elalikwahlula umgqomo okhanyayo obomvu kwiimitha ezibomvu neziluhlaza. Imijelo emitsha ebomvu neyeluhlaza ngokukhawuleza ke udibanise kunye ne-bridge eluhlaza ye-blue and pass through the rest of the engine.
Elinye iprojekti ye-Epson LCD esebenzisa i-laser edibeneyo kunye ne-phosphor yi-LS10500.
I-Laser / i-LED Hybrid (DLP) - Enye enye inguqu, esetyenziswa ngokuyinhloko nguCasio kwezinye zeeprojekti zabo ze-DLP, yi-Laser / LED injini yokukhanya ye-hybrid.
Kulo miselo, i-LED ivelisa ukukhanya okubomvu okufunekayo, ngelixa iLaser isetyenziselwa ukuvelisa ukukhanya okuluhlaza. Inxalenye yesibhakabhaka sokukhanya esibhakabhaka iyahlukana kwi-boramu eluhlaza emva kokushaya ivili le-phosphor.
Iimitha ezibomvu, eziluhlaza, kunye neziluhlaza zigqithise i-lens condenser kwaye zibonakalise kwi-Chip DLP DMD, ukugqiba ukudala umfanekiso, okwenziwa kwesikrini.
Iprojekti enye yeCasio eneInjini yeLayibrari yeLaer / LED yi-XJ-F210WN.
I-Bottom-To Laser okanye AkunakuLazara
Iiprojekti zeLaser zibonelela ngokubambisana ngokufanelekileyo kokukhanya okufunekayo, ukuchaneka kombala, kunye nokusebenza ngamandla kwamabhayisikobho kunye nokusetyenziswa kwetater.
Iiprojekti ezisekelwe kumaphulo ziyaqhubeka zilawulwa, kodwa ukusetyenziswa kwe-LED, iLat / Laser, okanye imithombo yokukhanya yeLaser iyanda. I-Lasers njengamanje isetyenzisiwe kwinani elinqinqiweyo leeprojekti zevidiyo, ngoko ziya kuba zibiza kakhulu (Amanani avela kwi-$ 1,500 ukuya kuma-3,000 angaphezulu kwee-3,000-kwakhona acinge ngeendleko zeskrini, kwaye kwezinye iimeko, iilensi).
Nangona kunjalo, njengoko ukufumaneka kwandisa kwaye abathengi bathenga iiyunithi ezingaphezulu, iindleko zokuvelisa ziya kuhla, ziphumela kwiiprojekti ze-Laser ezincinci-zithathele ingqalelo kwiindleko zokutshintsha izibane ngokungafanele zithathe i-lasers.
Xa ukhetha iprojekti yevidiyo -ngakhathaliseki ukuba luhlobo luni lomthombo olusebenzisayo, kufuneka ulungele indawo yokujonga indawo, uhlahlo lwabiwo-mali kunye nemifanekiso ifanele ukukholisa.
Ngaphambi kokugqiba ukuba ngaba isibane, i-LED, i-Laser, okanye i-LED / i-Laser hybrid yindlela ekhethekileyo kuwe, khangela umboniso wohlobo ngalunye.
Ukufumana okungakumbi kwimveliso yeprojekti yokukhanya kweprojekti, kunye nendlela yokwenza iprojekti yevidiyo, bhekisa kumacandelo ethu amanqaku: Iimpawu, i-Lumens, kunye noBhanya - Iiprojekti zeVVs vs VVs kunye nendlela yokumisela iprojekthi yeVideo
Inqaku lokugqibela-Njengokuba "ne-TV ye-TV" , i-laser (s) kwiprojekitha ayiyi kuvelisa iinkcukacha ngqo kumfanekiso kodwa inika umthombo wokukhanya owenza ukuba iiprojekti zibonise imifanekiso epheleleyo yemibala kwibala. Nangona kunjalo, kulula ukusebenzisa igama elithi "Laser Projector" kunokuba "iprojekti yeDLP okanye iLCD yeWindows Light Source".
