I-Plasma vs i-LCD vs i-LED vs i-DLP
Kungakhathaliseki ukuthi ucwaninga i-TV entsha ku-intanethi noma ubuka amamodeli amasha ezitolo , uzothola ubuchwepheshe obuningi bokuthi abakhiqizi ngokuvamile basebenzise amasethi we-HDTV anamuhla. Yonke inomgomo ofanayo - izinga elimnandi lezithombe - kodwa "iresiphi" ngayinye inezinhlamvu nezenzo. Lokhu kufanelekile ukwazi mayelana nokuthenga i-TV entsha . Phakathi nocwaningo lwakho, khumbula ukuthi yikuphi okubalulekayo, hhayi uhambo; isithombe esihle se-TV isithombe esihle se-TV kungakhathaliseki ukuthi isiphi ubuchwepheshe esetshenziswayo.
Ama-TV e-Plasma
I-Plasma yayiyi-teknoloji yokuqala ye-flat-TV engakwazi ukukhiqiza izithombe ezinhle zekhwalithi ezikrinini zasendlini zaseshashalazini ezingu-42 "nangaphezulu. Nakuba ochwepheshe abaningi be-plasma bekhiqiza isithombe esihle kunazo zonke, ama-TV ama-plasma awakhiwe ngenxa yokuncipha kwesabelo semakethe yama-TV e-LCD.
Ama-TV e-LCD
Nakuba kuthatha okwesikhashana i- LCD (i-liquid crystal display) ukuze ibambe ngokuvumelana nokwamukelwa kwemakethe kanye nemanani, lokhu manje kuyi-tekhnoloji evamile kakhulu ye-TV futhi itholakala kuluhlu lwezingqondo, ubukhulu kanye nokukhetha imodeli. Ngenxa yalolu hlu olubanzi, ikhwalithi yesithombe ingahluka kakhulu, ngezinye izikhathi ngisho naphakathi kwamamodeli ahlukene avela kumkhiqizo ofanayo.
Izinzuzo ze-LCD
Ama-TV e-LCD aklanyelwe ukuvimba ukukhanya okungaphandle, okusho ukuthi izikrini zabo zivame ukungabonakali futhi ukukhanya okuvela esikrinini kuvame ukubonakala ngokuphakeme kunamanye ubuchwepheshe. Ama-TV e-LCD nawo akhiqiza ukushisa okuncane futhi ngokuvamile adla ugesi amancane. Ama-TV e-ELCD avikelekile esikrinini "ukushisa" futhi uyakhetha kahle lapho izithombe ezimile ziyingxenye enkulu yezidingo zakho zokubuka. Ekugcineni, i-LCD izokunika ukhetho olukhulu lwamanani nobukhulu beskrini.
I-LCD Drawbacks
Ngaphezu kwamanye ubuchwepheshe be-TV, ama-TV e-LCD ahluka kakhulu ngekhwalithi yesithombe. Lokhu kuwumphumela wemvelo wenani elikhulu lamamodeli atholakalayo, kodwa futhi ngoba i-LCD ikhiqiza ukwakhiwa futhi abenzi abaningi balwela ukushaya amaphuzu amanani aphansi kakhulu, ikakhulukazi onobuhle bezinga lokungena. Inselelo enkulu yezobuchwepheshe beLCD yizithombe ezihamba ngokushesha; kwezinye izigcawu, ungabona umzila wamaphikseli noma ukubukeka "kwe-blocky" ngokunyakaza okusheshayo. Abakhiqizi bazama ukulungisa lokhu ngezithuthukisi ezihlukahlukene "zokunyakaza," ngezinye izikhathi ngempumelelo, ngezinye izikhathi ngaphansi kwalokho. Ama-TV e-LCD avamile nawo awakhiqiza umbala omnyama kanye nezinye ubuchwepheshe, okuholela emininingwaneni emincane kanye nokuphambene nalokho ongayithola kwenye indawo. Okokugcina, isithombe ku-TV eziningi ze-LCD sibonakala sihlukile uma ubuka kusukela kude kakhulu.
Ama-TV we-LED
I-LED (i-light emitting diode) Ama-TV empeleni yi-TV ye-LCD enendlela ehlukile yokukhiqiza ukukhanya. Njalo ukubonisa okusekelwe kwe-LCD kudinga ukuthi amaphikseli ayo "avuleke" ukuze akhiqize izithombe. Emasethini e-LCD avamile, isibani se-fluorescent ngemuva kwesethi sisetshenzisiwe, kepha kuma-LED amasethi, izibani ezincane ze-LED zisebenza esikhundleni salokhu. Kunezinhlobo ezimbili zamaTV we-LED. Omunye wabo ubizwa nge-LED "ukukhanya okukhawulelwe" - esikhundleni sesibani esikhulu ngemuva kwamaphikseli, izibani ezincane ze-LED ezungeze eceleni kwesikrini ziyasetshenziswa. Lena indlela ebiza kakhulu ye-LED. Ngendlela elula kakhulu (futhi ebiza kakhulu) ye-LED, "imigqa eminingana yezibani ze-LED" ibekwa ngemuva kwesikrini bese uvumela noma ukuvala amaphikseli "asendaweni" aseduze, ngokuya ngezidingo zesikhashana zohlelo ubukele. Lokhu kubangela ukungafani okungcono.
Izinzuzo ze-LED
Ngenxa yokuthi ukukhanya kwe-LED kukhanya futhi kuphumelela kakhulu kunokukhanyisa kwe-fluorescent, isithombe ku-TV ye-"pops" ye-LED okungaphezu kwesethi ye-LCD evamile, ngokungafani kahle nemininingwane, kuvame ukufinyelela ikhwalithi yesithombe yamasethi e-plasma angcono. Lokhu kuyiqiniso ikakhulukazi kumasethi we-DEL dimming local, okubizwa nangokuthi "ama-LED aphelele". Ama-LED asebenzisa ubuchwepheshe obungabonakali kakhulu bokukhanyisa ubuchwepheshe bungenziwa buncane kakhulu - ngokuvamile ngaphansi kwe-inch ebanzi. Nakuba kuhle ngezinga lokuzithokozisa, lo mphumelelo awunamthelela kukhwalithi yesithombe. Zombili izinhlobo ze-TV ze-TV zisebenza kangcono kunama-plasma noma i-LCD TV evamile, okusho ukuthi imali ephansi yegesi kanye nomndeni ovuthiwe.
Ama-Drawbacks e-LED
Ama-TV we-LED angabiza kakhulu kunezingcingo ze-LCD futhi kunokukhetha okuncane kwi-TV ye-LED; ngeke uthole okuningi kunama-brand noma ubukhulu beskrini ongakhetha kuzo. Kanti futhi, njengoba i-LED isisekelo sobuchwepheshe be-LCD, i-angle yokubuka kuyinkinga; ikhwalithi yesithombe ingahluka uma uhlala engeni eliphezulu kakhulu ku-TV.
Ama-TV we-DLP
Ngenkathi iningi lemakethe liye lashintshela kuma-TV-screen, abakhiqizi abaningana baqhubeka nokunikeza ama-TV amancane "asetshenzisiwe ngemuva" ngokusekelwe ku- Digital Light Processing (DLP) injini eyenziwe yiTexas Instruments ekuqaleni kwawo-1990. Lona ubuchwepheshe obufanayo obusetshenziselwa ukufakwa kwedijithali ezindaweni zeshashalazi ze-movie futhi usebenzisa i-chip ngezigidi zezibuko ezincane ezibonisa ukukhanya (nezithombe) esikrinini ngokusekelwe kwezidingo zesikhathi sangempela zohlelo lohlelo. Ngenkathi lawa maTV engekho flat, awekho ojulile njengama-TV anama-analog esikoleni esidala futhi afika ebangeni elimangalisayo lobukhulu bezinkrini.
Izinzuzo ze-DLP
I-DLP ubuchwepheshe obuvuthiwe obukwazi ikhwalithi yesithombe evelele. Isebenza kahle emakamelweni aqhakazile noma amnyama futhi inezici ezinhle zokubukwa kwe-off-angle. Ngaphandle kwekhwalithi yesithombe, inzuzo enkulu ye-DLP yi-bang ye-buck - ungathola isikrini esikhulu se-DLP ngemali encane kunomfanekiso wesikrini esiphathelene nosayizi ofanayo, futhi uma kwenzeka izikrini ezinkulu (amasentimitha angu-60 nangaphezulu) ngemali encane kakhulu. I-TV ye-DLP nayo iyatholakala kumamodeli we-3D.
I-DLP Imidwebo
Ama-TV e-DLP awahlali flat. Uzodinga isikhala esiningi se-shelf (noma isikhala esingaphansi) se-DLP TV, kodwa uma unekamelo lakho futhi ungacabangi ukuthi i-TV yakho ayihlali, lokhu akuyona inkinga.
