Chii DLP Technology Is
DLP inomiririra Digital Light Processing, iyo inofanirwa kujekesa mavhidhiyo, yakagadzirwa neTexas Instruments.
DLP tech inogona kushandiswa mune zvakasiyana-siyana zvevhidhiyo kuratidza mapurisa, asi inonyanya kushandiswa mumavhidhiyo emagetsi. Zvakakoshawo kuziva kuti munguva yakapfuura, teknolojia yeDLP yakashandiswa mune dzimwe terevhizheni (TV-projection) hazvisisipo).
Zvizhinji zvevhidhiyo mapurojekiti ekushandiswa kwevatengi vanoshandisa DLP purogiramu yekombiki yemifananidzo pachikona vachishandisa nzira inotevera:
Chiedza chinopenya chiedza kuburikidza negumbo rinotenderera, iro rinobva rabuda kubva kune imwe chip (inonzi DMD Chip) ine nzvimbo yakavharwa nezviratidzo zviduku zvakakura. Zviratidzo zvinoratidzika uye zvinozopfuura nepakati nepamusoro, uye pahwindo.
DMD Chip
Pakati pezvose DLP video projector ndiDMD (Digital Micromirror Device). Ichi chimiro che chip chinogadzirirwa kuitira kuti pixel yese igone kuratidza. Izvozvo zvinoreva kupi zvako kubva kune imwe kusvika kune miriyoni miviri micromirror pane DMD imwe neimwe, zvichienderana nechinangwa chekuratidzwa kwezviratidzo uye kuti girazi rinokurumidza kufamba rinodzorwa sei.
Sezvo vhidhiyo yemufananidzo inoratidzwa paDMD Chip. I-micromirror in the chip (yeuka: imwe neimwe micromirror inomiririra imwe pixel) uye inofambisa zvikuru nokukurumidza sezvo chifananidzo chinoshanduka.
Izvi zvinogadzira nheyo yakasimba yemufananidzo. Zvadaro, ruvara rwunowedzerwa sezvo chiedza chinopfuurira nepamusoro-kuruka chinotenderera gumbo uye rinoratidzirwa pane micromirrors paDLP chip sezvo ichikurumidza kuenda kumunhu kana kure nemuvara weguru uye chiedza chinobva.
Dhigirii rwemagromirror imwe neimwe pamwe chete negivha rinotenderera rinotarisa rinotarisa mararamiro emufananidzo wemufananidzo wakafananidzirwa. Sezvo chiedza chinosimudzirwa chinoputika kubva pamagetsi, inotumirwa kuburikidza ne-lens uye inogona kuratidzwa pane skrini huru yakakodzera yekushandiswa kwemitambo yemusha.
3-Chip DLP
Imwe nzira iyo DLP inoshandiswa (mumugwagwa wepamusoro wemusha kana kushandiswa kwema cinema) ndoshandisa imwe DLP chip yakasiyana yemuvara wega wega wekutanga. Rudzi urwu rwekugadzirisa runopedza kukosha kwemavara anofema.
Panzvimbo yehutachiona, chiedza chinobva kune rimwe chete chinyorwa chinopfurikidza nejeri, iro rinoumba zvakasvibirira zvitsvuku, zvitubu, uye bhuruu zvitsva. Iko kupatsanurwa kwemitsara inowanzoonekwa pane imwe neimwe yezvipi zvakasarudzwa kumusana wega wega wega, uye kubva ipapo, inoratidzwa pachikona. Iri shanduro inodhura zvikuru, kana ichienzaniswa nemuvara weguruji nzira, ndicho chikonzero nei isingawanzowaniki kune vatengi.
LED uye Laser
Kunyange zvazvo 3-Chip DLP yekombiyuta inodhura zvikuru kuita, dzimwe nzira mbiri, dzisina mari dzakashandiswa dzakashandiswa kubudirira (uye zvisingakwanisi) kuti ibvise chidimbu chekutsvaira gumbo.
Imwe nzira ndeyokushandisa chiedza che LED chiedza. Iwe unogona kuva neIndaneti yakasiyana yega yega yega ruvara rwekutanga, kana chichena che LED chinoparadzaniswa kuva mavara ekutanga achishandisa prism kana mafaira evara. Izvo zvinosarudzwa zvinongogumisa chete kudikanwa kweguruji, asi kunounza kupisa kwakanyanya, uye kunokonzera simba shoma kupfuura mwenje wechigarire. Kushandiswa kwekuwedzera kwechisarudzo ichi kwakakwira kune rimwe boka rezvinhu zvinonzi Pico Projectors.
Imwe nzira ndeyekushandisa Laser kana Laser / LED Hybrid chiedza chitubu, icho, se, chinonzi LED-sarudzo chete, haisi kungobvisa marara girasi, inoita kuti usanyanya kupisa, uye inotora simba shoma, asi inoshandawo kuvandudza ruvara rwekuberekwa nekupenya. Zvisinei, nzira ye laser inodhura kupfuura yakananga LED kana kuti Lamp / Color Wheel sarudzo (asi ichiri kudhura kudarika ye 3-chip option).
DLP Drawbacks
Kunyange zvazvo "imwe-chip uye ine magirasi" yeDLP yekombiyuta inogona kutengesa, uye inogona kubudisa migumisiro yakanaka kwazvo maererano nemirairo uye kusiyana, kune zvipingamupinyi zviviri.
Chimwe chinokanganisa chiyero chemuvara chiedza chinobuda (ruvara ruchenekera) hausi muzinga rimwechete semuchena chiedza chinobuda - kuti uwane mamwe mashoko verenga nyaya yangu: Video Projectors uye Color Brightness .
Yechipiri kukanganiswa kwevashandi veDLP video projection ndekuvapo kwe "The Rainbow Effect".
Mufaro wegoverwa igadziri inozviratidza sechidimbu chemavara pakati pekona nemeso apo muoni anotarisa nokukurumidza kubva kune rumwe rutivi kune rumwe ruvara pahwindo kana anotarisa nokukurumidza kubva pahwindo kusvika kune rumwe rutivi rwekamuri. Aya mavara mavara anotarisa semvura inoputika.
Nenzira yakanaka, izvi hazvisi kuitika nguva dzose, uye vanhu vazhinji havana tsitsi kune izvi zvachose. Zvisinei, kana iwe uchiziva izvi, zvinogona kukanganisa. Zvaunogona kuita kuti uve nemuorivhi zvinogadziriswa zvinofanira kutorwa paunenge watenga DLP video projector.
Uyezve, DLP vhidhiyo vhidhiyo vanoshandisa LED kana Laser chiedza chemvura hazvikwanisi kuratidzira mhepo yemvura, sezvo shandara yemavara haisipo.
