Ama-Plasma Television Basics kanye namathiphu okuthenga
Ama-TV e-Plasma, afana ne-TV ye-LCD, luhlobo lwethebula lethebula le-flat. Kodwa-ke, nakuba ngaphandle kokubili ama-Plasma ne-LCD TV abukeka afana kakhulu, ngaphakathi, kukhona ukungqubuzana okukhulu. Ukuze uthole okuningiliziwe kwalokho okudingeka ukwazi mayelana namathelevishini e-plasma, kanye nokunye ukusikisela okuthenga, hlola umhlahlandlela olandelayo.
QAPHELA: Ngasekupheleni kuka-2014, i-Panasonic, i-Samsung ne-LG yamemezela ukuphela kokukhiqizwa kwe-Plasma TV. Kodwa-ke, ama-Plasma TV angase athengiswe nge-imvume kanye nezimakethe eziyisikhathi esithile, ngakho-ke ulwazi olulandelayo luzoqhubeka luthunyelwe kuleli sayithi ukuze libhekiswe emlandweni.
Kuyini i-Plasma TV?
Ubuchwepheshe be-TV e-Plasma bufana nobuchwepheshe obusetshenziselwa isibani sokukhanya se-fluorescent.
Isibonisi ngokwazo sakhiwa ngamaseli. Ngaphakathi kweseli ngayinye amabili amapaneli angama-glass ahlukaniswa i-gap encane lapho i-neon-xenon igesi ifakwe khona futhi ifakwe ifomu le-plasma ngesikhathi sokukhiqiza.
Igazi lisebenza ngamandla kagesi ngezikhawu ezithile uma isethi ye-Plasma isetshenziswa. Igesi elikhokhiswayo libhekene ne-phosphors ebomvu, eluhlaza, neluhlaza okwesibhakabhaka, ngaleyo ndlela yakha isithombe se-TV.
Iqembu ngalinye le-phosphors ebomvu, eluhlaza neluhlaza okwesibhakabhaka libizwa ngokuthi i-pixel (isici sezithombe).
Ubuchwepheshe be-TV yama-plasma abufani nalokho okushiwo ngaphambili, i-Cathode Ray Tube, noma i-CRT TV. I-CRT ngokuyinhloko ithubhu enkulu yokuvutha lapho igoli le-elekthronikhi, elivela ephuzu elilodwa entanyeni ye-tube, lihlola ubuso bhubhu ngokushesha, futhi likhanyisa i-phosphors ebomvu, eluhlaza, noma eluhlaza okwesibhakabhaka. indawo ye-tube ukuze udale isithombe.
Inzuzo enkulu ye-Plasma phezu kwe-CRT ubuchwepheshe ukuthi, ngokusebenzisa iseli elivalwe nge-plasma esetshenziselwa i-pixel ngayinye, isidingo sokuba nesibhamu se-electron esithwetsheni sichithwe, okushiwo ukuthi sidinga isidingo se-Cathode Ray Tube enkulu ukukhiqiza ividiyo izithombe. Yingakho ama-TV we-CRT wendabuko afana namanye amabhokisi nama-Plasma TV amancane futhi aphansi.
Hlola uHistory of Plasma Television
Kuze kube nini ama-Plasma TV agcina?
I-Plasma TVs yasekuqaleni yayinezinkathi zokuphila kwamahora angu-30 000. Nokho, ngenxa yentuthuko yobuchwepheshe eyenziwe eminyakeni yamuva, ama-plasma amaningi athola amahora angu-60 000 amahora, kanti amanye amasethi alinganisiwe amahora angama-100,000.
Ukuthi ukulinganisa isikhathi kusho ukuthi isethi yePlasma izolahlekelwa cishe ngu-50% wokukhanya kwayo phakathi nesikhathi sokuphila esilinganisiwe. Ngokusekelwe ngisho nokulinganisa okulinganiselwe kwehora elingu-30,000 ekuseni, uma i-Plasma TV enjalo ihlala amahora angu-8 ngosuku, ukuphila kwayo ingxenye engaba ngu-9 - noma, uma amahora angu-4 ngosuku, isigamu sempilo singaba ngu-18 iminyaka (Double lezi zibalo ze-60,000 ihora lokuphila).
Kodwa-ke, ngezinye izinethi manje zilinganisiwe emahoreni angu-100,000, lokhu kusho ukuthi uma ubukela i-TV amahora angu-6 ngosuku, uzoba nesipiliyoni sokubuka esamukelekayo cishe iminyaka engama-40. Ngisho emahora angu-24 ngosuku, ihora elingu-100 000 ihora lesishiyagalolunye ukuphila sekuyiminyaka engaba ngu-10.
Khumbula ukuthi, njengoba kunjalo nanoma yibuphi ubuchwepheshe be-TV, ukubonisa isikhathi sokuphila nakho kungathinteka ngokuhlukahluka kwemvelo, njengokushisa, umswakama, njll. Nokho, ezimweni eziningi, i-Plasma TV inganikeza iminyaka eminingi yokubona okugculisayo.
Khumbula ukuthi i-TV evamile ilahlekelwa ukukhanya kwayo okungama-30% ngemuva kwamahora angu-20,000. Njengoba le nqubo ihamba kancane kancane, umthengi akaqapheli ngalomphumela, ngaphandle kwesidingo sokulungisa ngezikhathi ezithile ukukhanya nokuqhathanisa izilawuli ukukhokhela. Nakuba ukusebenza kwama-Plasma TVs ngamunye kungahlukahluka, jikelele, njengesigaba somkhiqizo, i-Plasma TV ingakhipha iminyaka eminingi yokubukela okumukelekile.
Ingabe ukuvuza kwe-TV yama-Plasma?
Igesi e-TV yama-Plasma ayifuni ngendlela yokuthi igesi elingaphezulu lingaphunywa khona. Isakhi ngasinye se-pixel sisakhiwo esiqinisekisiwe ngokuphelele (okubizwa ngokuthi iseli), okuhlanganisa amaphosphor, amashayeli okushaja kanye negesi le-plasma. Uma iseli lihluleka, alikwazi ukulungiswa ngokomzimba noma "ukuvuselela" igesi. Ngamanye amazwi, uma inani elikhulu lamaseli "liba mnyama" (nganoma yisiphi isizathu), iphaneli yonke idinga ukushintshwa.
Ingabe i-TV yamaPlasma ingasebenza ezindaweni eziphakeme?
Ukunciphisa ingcindezi yomoya wangaphandle ekhona ezindaweni ezingaphezulu kungaba yinkinga yamabhayisikobho e-plasma. Njengoba izakhi ze-pixel ku-TV yama-plasma empeleni ziyi-glass housings ezinama-gasi angavamile, umoya omncane udala ukucindezeleka okukhulu emagesi ngaphakathi kwezindlu. Ama-TV amaningi e-Plasma alinganisiwe ukuze asebenze kahle lapho, noma eduze, izimo zezinga elwandle.
Njengoba izinga lokuphakama landa, ama-Plasma TVs kudingeka asebenze kanzima ukuze akhokhele umehluko emoyeni womoya wangaphandle. Ngenxa yalokho, isethi izokhiqiza ukushisa okukhulu kanye nabalandeli bayo bokupholisa (uma unayo) kuzosebenza kanzima. Lokhu kungabangela ukuthi umthengi azwe "umsindo wokubamba". Ngaphezu kwalokho, okukhulunywe ngabo 30,000 kuya ku-60,000 ihora lesigamu sempilo (kuye ngokuthi umkhiqizo / imodeli) kwesikrini se-Plasma kuzoncishiswa ngandlela-thile.
Kubathengi abaningi lokhu akuyona inkinga, noma kunjalo kunezicabango uma uhlala endaweni engaphezu kwamamitha angu-4 000 ngaphezu kolwandle lolwandle. Uma uhlala endaweni engaphezu kuka-4,000 ft hlola nomthengisi wakho ukuze ubone ukuthi kungenzeka yini kube khona inkinga. Amanye ama-TV e-Plasma ayenamandla ngokwanele ukuze asebenze kahle ezindaweni ezingaphezulu kwamamitha angu-5000 noma ngaphezulu (empeleni, kukhona izinguqulo eziphakeme eziphezulu ze-TVs ezingama-8,000 ft).
Enye indlela yokuhlola lokhu, uma uhlala endaweni ephakeme kakhulu, ukuhlola ama-Plasma TV kumthengisi wangakini. Ngesikhathi ukhona, faka isandla sakho kule unit bese uqhathanisa ukufudumala okuvela esizukulwaneni sokushisa esengeziwe futhi ulalele umsindo wokuzwakalisa umsindo. Uma kuvela ukuthi i-Plasma TV ayamukeleki endaweni yakho, ungase ucabangele i-LCD TV esikhundleni. Ngakolunye uhlangothi lwalolu daba, ama-Plasma TV aqondiswe ngokukhethekile ekusetshenzisweni kokuphakama okuphakeme manje asejwayelekile - okungenani uma nje ama-Plasma TV azotholakala.
Ingabe ama-Plasma TV adala ukushisa?
Njengoba enye yezingxenye ezinkulu ze-Plasma TV igesi elikhokhiswayo, isethi iyofudumala kulokhu okuthinta ngemuva kokusebenza okwesikhashana. Njengoba iningi lamabhayisikobho e-Plasma kukhona udonga noma ukuma okuphakanyisiwe, kunomoya ojikelezayo, isizukulwane sokushisa, ngaphansi kwezimo ezivamile, ukushisa ngokuvamile akuyona inkinga (bheka umbuzo wangaphambilini ekusetshenzisweni okuphezulu). Kodwa-ke, kanye nesizukulwane sokushisa, ama-Plasma TVs asebenzisa amandla angaphezu kwesethi ejwayelekile ye-CRT noma i-LCD.
Into esemqoka ukukhumbula ukunikeza ikamelo lakho le-Plasma TV ngokwanele ukukhipha ukushisa okwenzayo.
Iyini i-Sub-Field Drive ku-Plasma TV?
Lapho uthengisa i-Plasma Television, njengoba nje nemikhiqizo eminingi ye-electronics abathengi, abathengi babhekene nezinamba eziningi kanye nemigomo ye-tech. Enye incazelo ehlukile kwi-Plasma Television iyinani le-Sub-Field Drive, elivame ukushiwo nge-480Hz, 550Hz, 600Hz, noma inombolo efanayo.
Thola imininingwane yalokho okushiwo yi- Sub-Field Drive ku-Plasma TV
Ingabe Wonke ama-HDTV ama-Plasma TVs?
Ukuze i-TV ibekwe njenge- HDTV, noma i-HDTV ilungile , i-TV kufanele ikwazi ukubonisa okungenani amaphikseli angu-1024x768. Amanye ama-Plasma TV aqala ukubonisa kuphela ama-852x480. Lawa maqoqo abizwa ngokuthi yi-EDTVs (ama-TV anwetshiwe noma ahanjisiwe) noma i-ED-Plasmas.
Ama-EDTV ngokuvamile anezixazululo zephikseli yangokwenyama ye-852x480 noma i-1024x768. I-852x480 imelela amaphikseli angu-852 kuwo wonke (kwesobunxele kuya kwesokudla) nama-pixel angu-480 phansi (phezulu kuya phansi) emkhathini weskrini. Amaphikseli angu-480 phansi aphinde amele inani lemigqa (imigqa yamaphikseli) ukusuka phezulu kuze kube phansi kwesikrini.
Izithombe kulezi zethi zibukeka zihle, ikakhulukazi kuma-DVD kanye nekhebula ledijithali elijwayelekile, kodwa akuyona i-HDTV yangempela. I-TV yama-plasma ekwazi ukubonisa izimpawu ze-HDTV ngokunembile inezixazululo zephikseli yangokwenyama okungenani 1280x720 noma ngaphezulu.
Bonisa izinqumo ze-852x480 no-1024x768 ziphakeme kune-TV evamile, kodwa hhayi ukuxazulula i-HDTV. I-1024x768 ifika eduze, ngoba ihlangabezana nezimfuneko zomugqa wamaphikseli oqondile wesithombe esichazwa phezulu, kodwa ayihlangabezani nezidingo zegqawu elilinganiselwe le-pixel for image full definition definition.
Ngenxa yalokho, abanye abakhiqizi babhala ama-TV angu-1024x768 ama-Plasma TV njenge-EDTV noma i-ED-Plasmas, kuyilapho abanye bekubhala njenge-Plasma HDTVs. Yilapho ukubuka okucacisiwe kubalulekile. Uma ufuna i-Plasma TV ye-HD ekwazi ngempela, hlola isinqumo se-pixel yangempela ye- 1280x720 (720p), 1366x768, noma i-1920x1080 (1080p) . Lokhu kuzohlinzeka ngokubonisa okunembile kwemithombo yomthombo ophezulu wokuchaza.
Njengoba ama-Plasma TV anenombolo ephelele yamaphikseli (okubizwa ngokuthi ukukhonjiswa kwe-pixel fixed), izimpendulo zesignali ezinezinqumo eziphakeme kumele zilandelwe ukulingana nokubala kwensimu ye-pixel yesikhangiso esithile se-Plasma. Isibonelo, ifomethi ejwayelekile ye-HDTV yokufaka i-1080i idinga ukuboniswa komdabu wama-pixels angu-1920x1080 ngokubonisa isithombe esisodwa kuya kwesinye se-HDTV.
Kodwa-ke, uma i-Plasma TV yakho inomkhakha we-pixel ka-1024x768 kuphela, isignali ye-HDTV yokuqala kufanele ilandelwe ukulingana nokubalwa kwamaphikseli ka-1024x768 ku-surface Plasma screen. Ngakho-ke, noma ngabe i-Plasma TV yakho ikhangiswa njenge-HDTV, uma inesibuko se-pixel se-pixel ka-1024x768 kuphela, izimpendulo ze-HDTV zizobe zisahlelwa phansi ukuze zivumelane nendawo yamaphikseli we-Plasma TV.
Ngendlela efanayo, uma une-EDTV enesinqumo esingu-852x480, noma yiziphi izimpawu ze-HDTV kuzodingeka zenziwe phansi ukuze zivumelane nomkhakha we-pixel 852x480.
Kuzo zonke izibonelo ezingenhla, ukuxazulula kwesithombe empeleni kubukwe esikrinini akuhambisani ngaso sonke isikhathi nesinqumo sesignali yokufaka yangempela.
Ekuphetheni, uma ucabangela ukuthengwa kwe-Plasma TV, qinisekisa ukuthi uhlola ukuhlola ukuthi i-EDTV noma i-HDTV. Imidlalo eminingi ye-Plasma TVs noma i-720p noma i-1080p isinqumo sokuzalwa, kodwa kukhona okuhlukile. Izinto ezibalulekile akutholaki ukudideka ngokuhambisana nokuboniswa kwesiginali sokufaka isignali ngokubambisana nalokho okwenziwe yi-pixel yangempela yokubonisa ukubonisa ikhono.
QAPHELA: Uma ufuna i-Plasma TV enesinqumo se-pixel somdabu wase-4K, vele ubambe amahhashi akho kuphela, okwakwenziwa kuphela ama-screen units amakhulu kakhulu ekusetshenzisweni kwezohwebo kuphela.
Ingabe i-Plasma TV isebenza neVCR yami endala?
Wonke ama-TV e-plasma okwenzelwe ukusetshenziswa kwabathengi azosebenza nanoma yikuphi ingxenye yevidiyo ekhona ne- AV ejwayelekile, ividiyo yenkampani, noma imiphumela ye- HDMI . Okuwukuphela kwento yokuxwayisa mayelana nokuyisebenzisa nge-VCR ukuthi kusukela i-VHS inesinqumo esincane futhi sinokungafani kahle kombala, ngeke kubonakale kahle ku-screen enkulu ye-Plasma njengoba kwenza ku-TV encane yamasentimitha angu-27. , P> Ukuze uthole okuningi kwe-Plasma TV yakho cabanga ukusebenzisa i-Blu-ray Disc Player, ungqimba, noma i-Upscaling player ye-DVD okungenani eyodwa yemithombo yakho yokufaka.
