I-LCD imele "I-Crystal Display Display". Ubuchwepheshe be-LCD bebukhona nathi amashumi ambalwa eminyaka futhi kusetshenziselwa izinhlelo zokusebenza ezihlukahlukene zokubonisa ividiyo, kufaka phakathi izibonisi zephaneli kumadivaysi kagesi kanye namadivaysi kagesi abathengi, kanye nesignali ye-digital. Mhlawumbe ukusetshenziswa okujwayelekile kakhulu kubathengi ukusetshenziswa kwabo kuma-TV .
Emathelevishini, ama-chips e-LCD ahlelwe ngaphesheya kwesikrini futhi asebenzise i-backlight ( uhlobo oluvame kakhulu yi-LED ), ama-TV e-LCD akwazi ukubonisa izithombe. Kuye ngesinqumo sesiboniso se-TV, inani lama-chips e-LCD asetshenziselwa ukubalwa ezinkulungwaneni (i-chip LCD ngayinye imelela i-pixel).
I-LCD isebenzisa ku-Projection yevidiyo
Nokho, ngaphezu kwama-TV, i-LCD Technology isetshenziswa kumavidiyo amaningi weprojekthi. Kodwa-ke, esikhundleni senombolo enkulu ye-LCD chips efakwe ngaphesheya kwesikrini, iprojekti yevidiyo isebenzisa ama-3D e-LCD ama-specially aklanyelwe ukudala nokudweba izithombe esikrinini sangaphandle. I-chips ezintathu ze-LCD ngayinye iqukethe inombolo efanayo yamaphikseli afana nesinqumo sokubonisa sephrojekthi, ngaphandle kwamasu wokuguqula ama-pixel asetshenziswe kwamanye ama-projector video ukuze abonise isinqumo esiphakeme "isithombe esingu-4K-like" ngaphandle kokuba nenombolo edingekayo yamaphikseli .
3LCD
Uhlobo olulodwa lwe-LCD yokubukwa kwevidiyo elisetshenzisiwe lisetshenziswe njenge-3LCD (okungenakudideka ne-3D).
Kwamaprosesa amaningi e-3LCD, umthombo wokukhanyisa okhanyise isibani uthumela ukukhanya okumhlophe emhlanganweni owenziwe nge-3- Dichroic Mirror ohlukanisa ukukhanya okumhlophe ibe yizibuko ezikhanyayo ezibomvu, eziluhlaza neziluhlaza okwesibhakabhaka, okuzobe zidlule emhlanganweni we-LCD chip oqukethe of chips ezintathu (elilodwa umbala ngamunye umbala oyinhloko). Le mibala emithathu ihlanganiswa besebenzisa i-prism, idluliselwe emhlanganweni we-lens bese ilandelwa esikrinini noma odongeni.
Nakuba imithombo yokukhanyisa esekelwe isibani isetshenziswa kakhulu, amanye amaprojekitha angu-3LCD angasebenzisa umthombo wokukhanya we- Laser noma we-Laser / LED , esikhundleni sesibani, kodwa umphumela wokugcina ufana - isithombe senzelwe esikrinini noma odongeni.
3LCD Izinguquko: LCOS, SXRD, no-D-ILA
Nakuba ubuchwepheshe be-3LCD bungenye yobuchwepheshe obuvame ukusetshenziswa kakhulu kumavidiyo wephrojekithi ( kanye ne-DLP ), kunezinhlobo ezihlukahlukene ezisekelwe e-LCD. Uhlobo olufanayo lwemithombo yokukhanya (Lamp / Laser) lungasetshenziswa ngalezi zinhlobonhlobo ze-LCD.
I-LCOS (i-Crystal Crystal ku-Silicon), i- D-ILA (i-Digital Imaging Light Amplification - esetshenziswe ngu-JVC) , ne- SXRD Silicon Crystal Display Display - esetshenziswe ngu-Sony), ihlanganisa ezinye zezici zombili ubuchwepheshe be-3LCD no-DLP.
Yiziphi izinto ezihlukahlukene ezintathu ezifana ngazo ukuthi esikhundleni sokukhanya okudlula i-LCD chips ukudala izithombe njengobuchwepheshe be-3LCD, ukukhanya kukhishwa ngempela ebusweni be-LCD chips ukudala izithombe. Ngenxa yalokho, uma kuziwa endleleni yokukhanya, i-LCOS / SXRD / D-ILA ibizwa ngokuthi "ubuchwepheshe bokubukeka", kuyilapho i-3LCD ibizwa ngokuthi "ubuchwepheshe" obuthakathaka.
3LCD / LCOS Izinzuzo
Enye yezinzuzo eziyinhloko zomndeni we-LCD / LCOS wezobuchwepheshe bokuhlola ividiyo ukuthi kokubili ikhono elimhlophe nelomkhiqizo linamandla. Lokhu kuqhathanisa nobuchwepheshe be-DLP ukuthi, nakuba inamandla okukhiqiza umbala omuhle kakhulu namanki amnyama, ayikwazi ukukhipha kokubili umbala omhlophe nombala ezingeni elifanayo lapho kwenzeka khona iphrojekti isebenzisa isondo lombala.
Kwamaprosesa amaningi e-DLP (ikakhulukazi ukusetshenziswa kwekhaya) ukukhanya okumhlophe kufanele kudlule ngesondo lombala eliqukethe izingxenye ezibomvu, eziluhlaza okwesibhakabhaka nohlaza okwesibhakabhaka, okunciphisa inani lokukhanya eliphuma ngakolunye uhlangothi. Ngakolunye uhlangothi, abalingisi be-DLP abasebenzisa ubuchwepheshe bamasondo obungewona umbala (njenge-LED noma i-Laser / LED emithombo yemithombo ye-Hybrid noma amamodeli we-3-chip) angaveza izinga elifanayo lomkhiqizo omhlophe nombala. Ukuze uthole imininingwane eyengeziwe, funda isihloko sethu somngane: Ama-Projectors Video neBrightness Brightness
3LCD / LCOS Izingozi
Iprojekti ye-LCD ngokuvamile iveza lokho okubizwa ngokuthi "umphumela womnyango wesikrini". Njengoba isikrini sakhiwa ngamaphikseli athile, amaphikseli angabonakala esikrinini esikhulu, ngaleyo ndlela anike ukubukeka kokubuka isithombe ngokusebenzisa "umnyango wesikrini".
Isizathu salokhu ukuthi amaphikseli ahlukaniswa nemingcele emnyama (engabhalwa). Njengoba ukwandisa usayizi wesithombe esicacisiwe (noma wehlise isinqumo ngesayizi esikrinini esifanayo) umkhawulo ngamunye we-pixel ungase ubonakale, ngaleyo ndlela unikeze ukubukeka kokubukwa kwesithombe "ngomnyango wesikrini". Ukuqeda le mphumela, abakhiqizi basebenzisa ubuchwepheshe obuhlukahlukene ukunciphisa ukubonakala kwemingcele ye-pixel engenziwanga.
Ngakolunye uhlangothi, kuma-projectors asevidiyo ase-LCD anama-high-resolution display ( 1080p noma ngaphezulu ), lo mphumela awubonakali kusukela amaphikseli encane futhi imingcele ilula, ngaphandle uma usondelene nesibuko, futhi isikrini sikhulu kakhulu.
Enye impikiswano engase ivele (nakuba yiyinto engavamile kakhulu) ukushisa kukaPixel. Njengoba i-chip LCD ikhiwa iphaneli lamaphikseli athile, uma i-pixel eyodwa ishisa iveza idayi elimnyama noma elimhlophe elidonswayo esithombeni esicacisiwe. Amaphikseli angeke akwazi ukulungiswa, uma i-pixel eyodwa noma ngaphezulu ishisa, yonke i-chip kufanele ishintshwe.
Okubalulekile
Amaphrojekithi wevidiyo afaka ubuchwepheshe be-LCD atholakalayo, athengekayo, futhi asebenza ngokusetshenziswa okuhlukahlukene, kusuka ebhizinisini nasemfundweni kuya emidlalo yaseshashalazini, imidlalo, nokuzijabulisa ekhaya jikelele.
Izibonelo zama-video esekelwe kuma-LCD asetshenziselwa ukusetshenziswa kwendawo yaseshashalazini zihlanganisa:
- I-Epson Home Cinema 2045 Iprojekti yevidiyo ye-LCD - Thenga kusuka ku-Amazon
- Iprojector yevidiyo ye-Sony VPL-HW45ES ye-SXRD - Thenga kusuka ku-Amazon
Ukuze uthole izibonelo eziningi, hlola uhlu lwethu lwe:
- Ama-Projectors amahle kakhulu wevidiyo (afaka kokubili izinhlobo ze-DLP ne-LCD).
- Ama-Projectors aphezulu we-1080p ne-4K (afaka kokubili izinhlobo ze-DLP ne-LCD).
